1.  The association between watching television and obesity in children of school-age in Saudi Arabia 
Background:
There is little information on the association between watching Television (TV) and obesity in the Arabian Peninsula.
Aim of the Study:
The aim of this study was to explore the association between the watching of television and obesity in Saudi children of school-age.
Materials and Methods:
A case-controlled study was conducted with students between the ages of 9 and 14 years who attended the school health clinic in King Abdulaziz Housing for National Guard (Iskan), Riyadh, Saudi Arabia, during the study period (February to April 2012). During each clinic, children were selected by simple random sampling (five obese and five non-obese). For data collection, two trained physicians interviewed the participants using a 20-item Arabic questionnaire. Well-trained nurses collected the anthropometric measurements of weight and height.
Results:
The study included 397 students. Higher (body mass index) BMI was associated with a higher number of televisions at home (P < 0.001), watching TV for more than three hours per day at the weekend (P = 0.047), eating more than three snacks per day (P = 0.005), watching TV at night (P = 0.026), and siblings’ decisions on how much TV to watch (P = 0.025). The prevalence of childhood obesity was significantly lower among those whose mothers determined how much TV they could watch (P = 0.03). In logistic regression analysis, the increase in the child's age, the presence of more than one TV at home, having his or her own TV, and an increase in the number of hours of watching TV over the weekend were significantly associated with an increased risk of childhood obesity. Personal computers and the Internet were not significantly associated with an increased risk of childhood obesity.
Conclusion:
The present investigation revealed that watching TV represents an important risk factor for obesity in children of school-age.

2.  Prevalence and age-of-onset distributions of DSM IV mental disorders and their severity among school going Omani adolescents and youths: WMH-CIDI findings 
Background
There is a dearth of studies exploring the magnitude of mental disorders amongst adolescents and youths in the Arab world. To our knowledge, this phase 2 survey in Oman is the first nationally representative school-based study to determine the prevalence of DSM-IV mental disorders (lifetime and over the preceding 12 months), their age-of-onset distributions and determine their severity over the past 12 months using the World Mental Health-Composite International Diagnostic Interview, the WMH-CIDI, used for international comparison.
Methods
A total of 1,682 (91.61%) students out of 1836 students who formed the phase 2 random sub-sample of a multi-stage, stratified, random sampling design (phase 1), participated in the face-to-face structured interview using the Arabic-version of WMH-CIDI 3.0.
Results
The phase 1 results using the General Health Questionnaire (GHQ-12) and Child Depression Inventory (CDI) showed depressive symptoms to be 17% prevalent in the larger sample of 5409 adolescents and youths. Amongst the phase 2 respondents from this sample, 13.9% had at least one DSM IV diagnostic label. The lifetime prevalence of Major Depressive Disorder (MDD) was 3.0%; Bipolar Mood Disorder (BMD) was 1%, Specific phobia 5.8% and Social phobia 1.6%. The female gender was a strong predictor of a lifetime risk of MDD (OR 3.3, 95% CI 1.7-6.3, p = 0.000); Any Mood Disorders (OR 2.5, 95% CI 1.4-4.3, p = 0.002) and Specific Phobia (OR 1.5, 95% CI 1.0-2.4, p = 0.047). The severity of illness for cases diagnosed with 12 month DSM IV disorders was found to be 80% lower in females (OR 0.2, 95%CI 0.0-0.8). The estimates over the previous 12 month period when compared with the lifetime prevalence showed a 25% to 40% lower prevalence for MDD, Specific phobia, Social phobia, Any Anxiety Disorders (AAD) and Any Mood disorders (AMD) while the rate was 80% lower for Separation Anxiety Disorder/Adult Separation Anxiety (SAD/ASA). Mood disorders were significantly lower in the 14-16 age groups (70% lower) in comparison to the older age groups and AMD showed a linear increase in prevalence across increasing age groups (p = 0.035).
Conclusion
The implications of the present findings are not clear cut, however this study endorses the adult CIDI studies findings that mental disorders do begin earlier in life. The relatively lower prevalence of DSM IV depressive disorders cautions against any conclusive interpretation of the inflated results based on the exclusive study of the depressive symptoms alone in the same sample in the same time period. The female gender proved to be a strong predictor of lifetime risk of MDD, any mood disorder and specific phobia. Under-reporting by males or some other gender-specific factors may have contributed to such a discrepancy. The odds of the severity of illness for cases with 12 month DSM IV disorders were significantly lower in females.

3.  Predicting tobacco use among high school students by using the global youth tobacco survey in Riyadh, Saudi Arabia 
Annals of Thoracic Medicine  2012;7(3):122-129.
OBJECTIVE:
To identify the predictors that lead to cigarette smoking among high school students by utilizing the global youth tobacco survey in Riyadh, Kingdom of Saudi Arabia (KSA).
METHODS:
A cross-sectional study was conducted among high school students (grades 10–12) in Riyadh, KSA, between April 24, 2010, and June 16, 2010.
RESULTS:
The response rate of the students was 92.17%. The percentage of high school students who had previously smoked cigarettes, even just 1–2 puffs, was 43.3% overall. This behavior was more common among male students (56.4%) than females (31.3%). The prevalence of students who reported that they are currently smoking at least one cigarette in the past 30 days was 19.5% (31.3% and 8.9% for males and females, respectively). “Ever smoked” status was associated with male gender (OR = 2.88, confidence interval [CI]: 2.28–3.63), parent smoking (OR = 1.70, CI: 1.25–2.30) or other member of the household smoking (OR = 2.11, CI: 1.59–2.81) who smoked, closest friends who smoked (OR = 8.17, CI: 5.56–12.00), and lack of refusal to sell cigarettes (OR = 5.68, CI: 2.09–15.48).
CONCLUSION:
Several predictors of cigarette smoking among high school students were identified.

4.  Sexual behaviour of adolescents in Nigeria: cross sectional survey of secondary school students 
BMJ : British Medical Journal  2003;326(7379):15.
Objectives
To determine whether family structure (polygamous or monogamous) is associated with sexual activity among school students in Nigeria.
Design
Cross sectional school survey with a two stage, clustered sampling design.
Participants
4218 students aged 12-21 years attending 39 schools in Plateau state, Nigeria. Responses from 2705 students were included in the analysis.
Main outcome measure
Report of ever having had sexual intercourse. Variables of interest included sexual history, age, sex, religion, family polygamy, educational level of parents, having a dead parent, and sense of connectedness to parents and school.
Results
Overall 909 students (34%) reported ever having had sexual intercourse, and 1119 (41%) reported a polygamous family structure. Sexual activity was more common among students from polygamous families (42% of students) than monogamous families (28%) (χ2=64.23; P<0.0001). Variables independently associated with sexual activity were male sex (adjusted odds ratio 2.52 (95% confidence interval 2.05 to 3.12)), older age (1.62 (1.24 to 2.14)), lower sense of connectedness with parents (1.87 (1.48 to 2.38)), having a dead parent (1.59 (1.27 to 2.00)), family polygamy (1.58 (1.29 to 1.92)), lower sense of connectedness with school (1.25 (1.09 to 1.44)), and lower educational level of parents (1.14 (1.05 to 1.24)). Multistep logistic regression analysis showed that the effect of polygamy on sexual activity was reduced by 27% by whether students were married and 22% by a history of forced sex.
Conclusions
Secondary school students in Nigeria from a polygamous family structure are more likely to have engaged in sexual activity than students from a monogamous family structure. This effect is partly explained by a higher likelihood of marriage during adolescence and forced sex. Students' sense of connectedness to their parents and school, regardless of family structure, decreases the likelihood of sexual activity, and fostering this sense may help reduce risky sexual behaviour among Nigerian youth.
What is already known on this topicIn 2000 Nigeria developed a national health policy aimed at preventing behaviour among adolescents leading to sexually transmitted infections (including HIV), pregnancy, and dropout from schoolEffective interventions in Nigeria have been hampered by inadequate information on contextual factors associated with sexual behaviour of adolescentsIn Western countries adolescents' sense of connectedness to their parents and to school is inversely associated with risky sexual behaviour, but these effects may differ in countries where polygamy is prevalent and where school attendance is lowWhat this paper addsA polygamous family structure is associated with early sexual activity among adolescents, an effect partly explained by a higher likelihood of marriage and history of forced sexual intercourseA greater sense of connectedness to parents and school decreases the likelihood of sexual activity, regardless of family structure

5.  Surveillance of Middle and High School Mental Health Risk by Student Self-Report Screener 
Introduction:
A 2009 National Academies of Sciences report on child mental health prevention and treatment concluded that screening for mental health risk is an essential component of service delivery. To date, however, there are few practical assessments available or practices in place that measure individual child risk, or risk aggregated at the school or community level. This study examined the utility of a 30-item paper and pencil student self-report screener of behavioral and emotional risk (BER) for surveying community risk among 7 schools.
Methods:
In 2010, 2,222 students in 3 middle and 4 high schools in a medium-sized school district in Georgia were administered the Behavioral and Emotional Screening System Self-Report Child/Adolescent form (BESS Student). The BESS is designed to measure 4 sub-syndromal BER factors for developing mental health disorders: inattention/hyperactivity, internalizing, school problems, and personal adjustment. Analysis of Variance and Chi Square analyses were used to assess the association between adolescent self-reported BER as an indicator of school BER, grade level, child ethnic identification and gender, socioeconomic status, and special education placement status.
Results:
BESS scores differentiated well between schools for overall BER and special education status, as well as between grade levels, ethnicity, and gender groups. One high school, known by the school administration to have numerous incidents of student behavior problems, had the most deviant 4 BER domain scores of all 7 schools. Girls rated themselves as having a higher prevalence of BER (14%) than boys (12%); middle school students reported fewer difficulties than high school students.
Conclusion:
Middle and high school students were capable of identifying significant differences in their own BER across schools, suggesting that universal mental health risk screening via student self-report is potentially useful for identifying aggregated community risk in a given school that may warrant differential deployment of mental health prevention and intervention strategies. BESS results reliably identified individual mental health risk associated with special education placement, which is documented to lead to poor school outcomes such as school dropout and lack of enrollment in post-secondary education.

6.  Prevalence of psychological symptoms in Saudi Secondary School girls in Abha, Saudi Arabia 
Annals of Saudi Medicine  2009;29(4):275-279.
BACKGROUND AND OBJECTIVES:
Adolescence is characterized by rapid physiological, social and cognititive changes. Aim of the present work is to study mental health of Saudi adolescent secondary school girls in Abha city, Aseer region, Saudi Arabia.
METHODS:
A cross-sectional study was conducted in 10 secondary schools for girls using the Arabic version of the symptom-revised checklist 90 (SCL 90-R), a mental health questionnaire that was administered to the girls by fourth-year female medical students.
RESULTS:
The most prevalent mental symptoms in the 545 female students were phobic anxiety (16.4%), psychoticism (14.8%), anxiety (14.3%), and somatization (14.2%). The prevalence of depression, paranoid ideation and interpersonal sensitivity amounted to 13.9%, 13.8% and 13.8%, respectively. The least prevalent mental symptoms were hostility (12.8%) and obsessive-compulsive behavior (12.3%). Overall, psychological symptoms (in terms of a positive global severity index) were found in 16.3% of the girls. In a multivariate logistic regression analysis, no significant relationship was found with sociodemographic factors.
CONCLUSION:
Psychological symptoms and disorders are prevalent in secondary school girls and health professionals need to be able to recognize, manage and follow-up mental health problems in young people. Further research is needed to explore the magnitude of the problem at the national level.

7.  Physical activity, sedentary behaviors and dietary habits among Saudi adolescents relative to age, gender and region 
Background
Few lifestyle factors have been simultaneously studied and reported for Saudi adolescents. Therefore, the purpose of the present study was to report on the prevalence of physical activity, sedentary behaviors and dietary habits among Saudi adolescents and to examine the interrelationships among these factors using representative samples drawn from three major cities in Saudi Arabia.
Methods
This school-based cross-sectional study was conducted during the years 2009-2010 in three cities: Al-Khobar, Jeddah and Riyadh. The participants were 2908 secondary-school males (1401) and females (1507) aged 14-19 years, randomly selected using a multistage stratified sampling technique. Measurements included weight, height, sedentary behaviors (TV viewing, playing video games and computer use), physical activity using a validated questionnaire and dietary habits.
Results
A very high proportion (84% for males and 91.2% for females) of Saudi adolescents spent more than 2 hours on screen time daily and almost half of the males and three-quarters of the females did not meet daily physical activity guidelines. The majority of adolescents did not have a daily intake of breakfast, fruit, vegetables and milk. Females were significantly (p < 0.05) more sedentary, much less physically active, especially with vigorous physical activity, and there were fewer days per week when they consumed breakfast, fruit, milk and diary products, sugar-sweetened drinks, fast foods and energy drinks than did males. However, the females' intake of French fries and potato chips, cakes and donuts, and candy and chocolate was significantly (p < 0.05) higher than the males'. Screen time was significantly (p < 0.05) correlated inversely with the intake of breakfast, vegetables and fruit. Physical activity had a significant (p < 0.05) positive relationship with fruit and vegetable intake but not with sedentary behaviors.
Conclusions
The high prevalence of sedentary behaviors, physical inactivity and unhealthy dietary habits among Saudi adolescents is a major public health concern. There is an urgent need for national policy promoting active living and healthy eating and reducing sedentary behaviors among children and adolescents in Saudi Arabia.

8.  Cross-sectional study on the relationship between life events and mental health of secondary school students in Shanghai, China 
Shanghai Archives of Psychiatry  2012;24(3):162-171.
Background
The relationship of demographic factors and negative life events to the mental health of mainland Chinese school students has not been fully explored.
Aim
Assess the prevalence of different types of life stressors among secondary school students and identify the demographic characteristics and types of life events that are most closely associated with perceived psychological difficulties in these students.
Methods
This cross-sectional study administered two self-completion questionnaires to a stratified random cluster sample of 1818 students from four secondary schools in two districts of Shanghai: the Strengths and Difficulties Questionnaire (SDQ) and an abbreviated version of the Adolescent Self-rating Life Events Checklist (ASLEC) that assesses 11 negative life events.
Results
Academic stress (74%), criticism from others (66%), family conflict (29%) and peer bullying & discrimination or interpersonal conflict (26%) were the most frequently reported negative life events, but their prevalence varied significantly by gender, type of school and urban versus rural residence. Similarly the level of reported psychological stress associated with life events, the total perceived psychological difficulty, and the level of pro-social behavior in the students varied significantly between different groups of students. Multivariate linear regression analysis identified the following independent predictors of high perceived psychological difficulty in the prior 6 months (in order of importance): high total stress score from negative life events in the prior year, experiencing peer bullying & discrimination or interpersonal conflict, not experiencing the death of a family member, male gender, attending a school in a rural district, and not suffering from a major disease or physical impairment. The independent predictors of a high level of pro-social behavior were high total stress score from negative life events, attending an urban school, female gender, attending a regular-tier school (vs. a high-tier school), experiencing peer bullying & discrimination or interpersonal conflict, not experiencing the death of a family member, and attending a middle school (vs. a high school).
Conclusion
Negative life events are one of many factors associated with perceived stress and level of pro-social behavior in secondary school students. Prospective studies are needed to clarify the causal pathways that connect stress with negative life events in students and to develop and test cohort-specific interventions aimed at decreasing stress and increasing pro-social behaviors.

9.  The Global Youth Tobacco Survey: 2001–2002 in Riyadh region, the Kingdom of Saudi Arabia 
Background
Tobacco use is a major public health problem, and its prevalence is globally increasing, especially among children and adolescents.
Objective
The Global Youth Tobacco Survey aimed to explore the epidemiological trends and risk factors of tobacco smoking among intermediate school boys in Riyadh region of the Kingdom of Saudi Arabia.
Method
A two-stage cluster sample design was used to produce a representative sample of male students from selected schools. The participants (n = 1830) self recorded their responses on the Global Youth Tobacco Survey questionnaire.
Results
Lifetime prevalence of cigarette smoking was 35%, while 13% of students currently used other tobacco products. About 16% of students currently smoked at home, and 84% of students bought cigarettes without any refusal from storekeepers. Thirty-one percent and 39% of students were exposed to secondhand tobacco smoke inside and outside the house, respectively, which was definitely or probably harmful to health as opined by 87% of participants, and 74% voiced to ban smoking from public places. Among current smokers, 69% intended (without attempt) to quit and 63% attempted (but failed) to quit during the past year. Almost an equal number of students saw antismoking and prosmoking media messages in the last month, and 28% of students were offered free cigarettes by a tobacco company representative. In schools, more than 50% of students were taught about the dangers of cigarette smoking in the last year. Smoking by parents, older brothers, and close friends, watching prosmoking cigarette advertisements, free offer of cigarettes by tobacco company representatives, perception of smoking being not harmful, and continuing smoking which can be easily quit significantly increased the odds of smoking by students.
Conclusion
The common use of tobacco in school populations needs to be addressed by, among other tobacco control measures, a strict ban on cigarette selling to minors and intensive regular tobacco control campaigns involving health and religious messages.

10.  Prevalence of Smoking and its Related Behaviors and Beliefs Among Secondary School Students in Riyadh, Saudi Arabia 
Objective:
To estimate the prevalence of smoking among secondary school students in National Guard area of Riyadh, and explore the reasons for the smoking and the attitude of non-smoker toward smoking habit.
Design:
A cross-sectional study was conducted in June 2009. By random sampling technique 255 students were enrolled from secondary school of National Guard area, Riyadh, Saudi Arabia. A self-administered questionnaire was used for data collection.
Results:
Current smokers represented 28.6% of the students. The most common reasons for smoking were: having free time (81.6%), for the relief of stress (63.2%) and seeing some of their teachers smoking (61.8%).
Most of the smokers started the habit before the age of 15 years old (89%). 84% of non-smokers suggested to ban smoking in public places. 42.2% of students were planning to start smoking in future.
Religion was the most important reason for not smoking among non smokers.
Conclusion:
The prevalence of smoking is big enough a problem to be considered as a warning for an impending epidemic Health education provision should have a greater role in schools Governmental commitment and social support are vital if health education and awareness and especially quit smoking programs are to be implemented and sustained.

11.  Determinants of sexual health knowledge in adolescent girls in schools of Riyadh-Saudi Arabia: a cross sectional study 
BMC Women's Health  2013;13:19.
Background
There are many social and cultural factors affecting the sexual knowledge of adolescents. This study measured the sexual health knowledge level of adolescents and identified its association with role of parents, friends and school environment in adolescent girls in Riyadh, Saudi Arabia.
Methods
Four hundred and nineteen Saudi female students belonging to intermediate and secondary grades were randomly selected from four public and private girl schools. 255 (69.8%) students were ≤15 years and 164 (39.2%) were >15 years. A self-administered structured questionnaire comprising of socio-demographic information, role of parents and teachers, availability of school curriculum on sexual health was used. Sexual health knowledge was assessed through questions on identification of physical changes during puberty for ≤15 years and separate questions on sexually transmitted infections for >15 years.
Results
54% of ≤15years and 70.7% of >15 years had poor sexual health knowledge. Multivariate analysis found determinants for poor sexual health education in ≤15years are: lower education level of both parents (OR 10.87; 95% CI 2.44–48.38), second birth order or more (OR 2.32; 95% CI 1.24–4.33) and absence of school curriculum on sexual health (OR 0.56; 95% CI 0.33–0.95). Determinants for >15 years of age are : mothers with low literacy (OR 3.08, 95% CI 1.42–6.71), as for sources of poor sexual knowledge : parents (OR 10.10; 95% CI 2.70–37.74), schools (OR 6.95; 95% CI 1.95–24.78) maids (OR 4.57; 95% CI 1.26–16.59) and media (OR 5.12; 95% CI 1.29–20.07) were statistically significant factors.
Conclusion
Government agencies with collaboration of all stake holders should develop policies and programs for implementing and evaluating integrated and comprehensive sexual educational programs for adolescents in Saudi Arabia.

12.  Prevalence of Addiction to the Internet, Computer Games, DVD, and Video and Its Relationship to Anxiety and Depression in a Sample of Iranian High School Students 
Objective: The objective of this study was to assess the prevalence of addiction to the Internet, computer games, DVD, and video and its relationship to anxiety and depression in a sample of Iranian high school students.
Methods: In this cross-sectional study 1020 high school students (males and females) were selected randomly from different areas of Shiraz city in southern Iran. They were interviewed according to the Diagnostic and Statistical Manual of Mental Disorders, 4th ed (DSM-IV) criteria.
Results: About 50% of the students were females, 277 students (27.2%) were studying in the first year of high school, 242 (23.7%) were in the second year, and others in the third year. The prevalence of anxiety was significantly higher in females than in males (p < 0.05). The prevalence of anxiety was lower among students of the third year (p < 0.05). The prevalence of depression was significantly higher in students with lower economic status defined as family monthly income. Internet dependence was seen only in 5 students. The prevalence of anxiety was significantly higher in the students who used internet for chatting, amusement, and reading news (p < 0.05). The prevalence of anxiety was significantly higher in students who were DVD or video CD dependents (p < 0.05). The students who used especial drugs or had especial diseases had higher rates of depression and anxiety (p < 0.05).
Conclusion: Internet addiction may cause depression and anxiety in high school students. It seems necessary to develop an Internet addiction prevention program for adolescents taking into account the psychological factors such as depression and Internet use habits.

13.  School difficulties in immigrant adolescent students and roles of socioeconomic factors, unhealthy behaviours, and physical and mental health 
BMC Public Health  2012;12:453.
Background
School is a multi-cultural setting where students need social, material, physical, and mental resources to attain school achievement. But they are often lacking, especially for immigrant students. In an early adolescence context, this study assessed risk for school difficulties among European and non-European immigrants and the roles of socioeconomic characteristics, physical health, psychological health, social relationships, living environment, and unhealthy behaviours.
Methods
This cross-sectional study included 1,559 middle-school adolescents from north-eastern France, who completed a self-administered questionnaire including socioeconomic characteristics (gender, age, family structure, father’s occupation, and family income), WHO-Quality of life (measuring the four dimensions physical health, psychological health, social relationships, and living environment), unhealthy behaviours (last-30-day uses of tobacco, alcohol, cannabis, and other illicit drugs and no regular sports/physical activities), grade repetition, low school performance (<10/20), and school dropout ideation at 16 years. Data were analyzed using logistic models.
Results
Grade repetition affected 14.8% of students, low school performance 8.2%, and school dropout ideation 3.9%. European immigrants had a higher risk for grade repetition only with a gender-age-adjusted odds ratio (OR) of 2.44, vs. French students. This odds ratio decreased to 1.76 (contribution 47%) with further adjustment for all confounders (family structure, father’s occupation, family income, physical health, psychological health, social relationships, living environment, and unhealthy behaviours). Non-European immigrants had a statistically higher risk for all grade repetition, low school performance, and school dropout ideation with ORs of 3.29, 3.02, and 3.42, respectively vs. French students. These odds ratios decreased to 1.76, 1.54, and 1.54, respectively (contributions 66%, 73%, and 78%) with further adjustment for all confounders.
Conclusions
Compared with French students, European immigrant students were more affected only by grade repetition while non-European immigrant students by all grade repetition, low school performance, and school dropout ideation. The contribution of socioeconomic characteristics, physical health, psychological health, social relationships, living environment, and unhealthy behaviours was very high and much higher for non-European than for European immigrant students. Public policy should focus on these factors and services to reduce school difficulties.

14.  Prevalence and characteristics of cigarette smoking among 16 to 18 years old boys and girls in Saudi Arabia 
Annals of Thoracic Medicine  2011;6(3):137-140.
OBJECTIVE:
To study the prevalence and characteristics of cigarette smoking among secondary school students (16- to 18-year-old boys and girls) in Riyadh city, Saudi Arabia.
METHODS:
We applied a standard two-stage, cross-sectional study design. Secondary schools for both boys and girls in Riyadh city were randomly selected using a cluster sampling method. We used the global youth tobacco survey (GYTS) tool to achieve our objectives.
RESULTS:
Among 1272 students (606 boys and 666 girls), the prevalence of those ever smoked cigarettes was 42.8% (55.6% of boys and 31.4% of girls). The prevalence of current smoking was 19.5% (31.2% of boys and 8.9% of girls). Despite the fact that the majority of students think smoking is harmful, most do not wish to stop smoking, and they had not tried to stop in the past year. Cigarette smoking is significantly associated with the male gender, having friends who smoke, and having parents who smoke, but is not significantly associated with the type of school attended.
CONCLUSION:
Smoking prevalence among secondary schools students in Saudi Arabia is high and alarming. There is a need to implement an education program about the risks of smoking and to include parents and friends as healthy models to prevent students from beginning to smoke.

15.  Students’ attitude toward use of over the counter medicines during exams in Saudi Arabia 
Purpose
To explore the use of over the counter (OTC) medicines among students during exams in Riyadh City, Kingdom of Saudi Arabia.
Method
A cross-sectional study was designed; using a self-administered twenty-two item online questionnaire for the students’ convenience and easy response disclosure. Data were analyzed using Statistical Package for Social Science (SPSS) version 13®.
Results
A total of N = 1596 students participated in this survey, of whom 829 (51.9%) were university students and 767 (48.1%) were high school students. Overall, 80.0% of the respondents disclosed the use of OTC non-steroidal anti-inflammatory drugs for headache and pain relief. In addition, other substances used during the exams were Energy Drinks (5.0%), Flu Medication (5.0%), Vitamins (5.0%) and Antibiotics (5.0%). Female students were found to be more knowledgeable about safety issues concerning the use of OTC medicines (5.11 ± 1.27, p = <0.001) than male students. Ease in access to OTC medicine, availability of pharmacist consultation and advertisement in print and electronic media were the main factors disclosed by the respondents that may result in an increase in the use of OTC products. The use of OTC medicines was generally higher among female students (p = 0.001).
Conclusion
The use of OTC medication during exams was more among high school and university students. Gender, age and educational institution were found significantly affecting the use of OTC medicines during exams.

16.  Prevalence of PTSD and Depression among Junior Middle School Students in a Rural Town Far from the Epicenter of the Wenchuan Earthquake in China 
PLoS ONE  2012;7(7):e41665.
Context
On May12th 2008, a devastating earthquake measuring 8.0 on the Richter scale, struck Wenchuan county and surrounding areas in China. The prevalence of mental illness among children and adolescents in a rural town far from the earthquake epicenter is unknown.
Objective
To assess the prevalence of posttraumatic stress disorder (PTSD) and depression among junior middle school students in a rural town Ningqiang county, 327 km from the earthquake epicenter.
Design, Setting, and Participants
A population-based mental health survey was conducted in March, 2009.
Main Outcome Measure
Survey Self-designed General Condition Survey Scale, Children's Revised Impact of Event Scale (CRIES-13), and the Depression Self-rating Scale for Children (DSRSC) were used to sample 1,841 junior middle school students in Ningqiang county, ten months after the Wenchuan earthquake.
Results
The prevalence rate of a high-risk for PTSD was 28.4%, with 32.7% among females, 23.8% among males (female vs. male, p<0.001), 38.6% in the severe exposure group and 24.3% in the mild exposure group (severe vs. mild exposure, p<0.001). For depressive symptoms, the overall prevalence was 19.5%, with 24.0% among females, 14.7% among males, 24.5% in the severe exposure group and 17.5% in the mild exposure group (female vs. male, p<0.001; severe vs. mild exposure, p<0.001, respectively). In multivariate analysis, factors such as “having felt despair”, or “danger” and “having own house destroyed or damaged” were significantly associated with PTSD symptoms. Female gender and delayed evacuation in females, and earthquake related experiences in males were significantly associated with depression.
Conclusion
Traumatic events experienced during the earthquake were significantly associated with symptoms of PTSD and depression in children and adolescents, ten months after the Wenchuan earthquake. These data highlight a need for mental health services for children and adolescents in rural areas, far from earthquake epicenters.

17.  Association between binge drinking, type of friends and gender: A cross-sectional study among Brazilian adolescents 
BMC Public Health  2012;12:257.
Background
Hazardous drinking among adolescents is a major public health concern. The purpose of this study was to examine the prevalence of binge drinking/alcohol consumption and its association with different types of friendship networks, gender and socioeconomic status among students in Belo Horizonte, Minas Gerais, Brazil.
Methods
We conducted a cross-sectional study on a representative random sample of 891 adolescents (41% male, aged 15–19 years) from public and private schools in 2009–2010. Information on friendship networks and binge drinking was collected using two validated self-administered questionnaires: the Integrated Questionnaire for the Measurement of Social Capital and the first 3 items in the Alcohol Use Disorders Identification Test (AUDIT C). We used the area-based Social Vulnerability Index (SVI), mother and father’s educational background, and the type of school to assess socioeconomic status. The chi-squared test was used to examine the associations between sample characteristics or the type of friends and binge drinking (p-values <0.05 were considered statistically significant). Ordinal logistic regression was used to estimate the association between binge drinking and the independent variables.
Results
A total of 321 (36%) adolescents reported binge drinking (5 or more drinks in one occasion), and among them, 233 (26.2%) adolescents reported binge drinking less than monthly to monthly, and 88 (9.9%) weekly to daily. Binge drinking was associated with being male (OR = 1.52, 95% CI 1.01–2.28) and with living in a low vulnerability area (having the best housing conditions, schooling, income, jobs, legal assistance and health) (OR = 1.66, 95% CI 1.05–2.62). Students who reported that their closest friends were from school (as opposed to friends from church) had an increased risk of binge drinking (OR = 3.55, 95% CI 1.91–5.87). In analyses stratified by gender, the association was significant only among the female students.
Conclusions
The prevalence of binge drinking was high in this sample of Brazilian adolescents, and gender, low social vulnerability and friendship network were associated with binge drinking.

18.  Symptoms of anxiety and depression in adolescent students; a perspective from Sri Lanka 
Background
Sri Lanka recorded an extraordinary high suicide rate for adolescents aged 15 - 19 in the early 1990s (46.5/100,000). With this in perspective, the Ministry of Health in Sri Lanka recommends school programmes for adolescents by mental health units of local hospitals.
Methods
We conducted cross sectional surveys to screen for symptoms of anxiety and depression among students aged 14 - 18 during school mental health programmes. Two schools were randomly selected within the Ratnapura municipality (urban population of approx. 50,000), Sri Lanka and all students aged 14-18 were assessed with self administered (pre tested, Sinhalese translations) questionnaires [Center for epidemiologic studies depression scale, Anxiety screening test of suicide and mental health association international].
Results
A total of 445 students were assessed (male-54.4%, female 45.6%). Thirty six percent screened positive for depression (mild depression-17%, severe depression-19%) and 28% screened positive for severe anxiety. Females screened positive for depression and anxiety significantly more than the males (p = 0.0001, 0.005 respectively). Students in classes facing barrier examinations at the end of the year had the highest positivity rates. Examination related issues (36%) were the most commonly cited problem.
Recommendations
It is recommended that:
1. School mental health development programmes in Sri Lanka concentrate more on reducing examination related stress, and in particular focus on the female students
2. Policy decisions are made to reduce competition for higher education
3. A nationally coordinated survey on mental health of adolescent students is carried out utilizing the island-wide network of medical officers of mental health.

19.  PERCEPTION AND SATISFACTION OF SECONDARY SCHOOL STUDENTS WITH THE DERMATOLOGICAL SERVICES IN RIYADH CITY 
Background:
Health care that meets patient's expectations inevitably leads to a high level of patient satisfaction and in turn to an improved compliance of the patient with the prescribed management. Accordingly, health care services are more likely to improve. Numerous factors have been associated with patient satisfaction and studies have been done to investigate this relationship. However, not much work has been done in the field of dermatological service.
Objective:
This study was designed to investigate the experience, satisfaction and expectations of adolescents of the dermatological services provided in the outpatient ambulatory facilities.
Methods:
A cross-sectional study was conducted on 700 male and female secondary school students in Riyadh in Saudi Arabia. A self-administered questionnaire was used to collect data from the students. Data were related to the perception, expectation and satisfaction of a specific group of students. The overall and different items of satisfaction with the dermatological service including satisfaction with the physician providing the service, and satisfaction with the setting of the care were estimated.
Results:
The age range was 15-29 years with a mean of 18.1 ± 1.8 years. Of the 517 (74%) respondents, 267 (51.6%) males and 250 (48.4%) females, 457 (88.4%) were Saudis. With regard to expectation and preference, 385 (73.9%) would like to have dermatologists at each PHC center; 310 (59.5%) preferred a government setting for treatment. Statistically significant gender preference was observed (p<0.001); males preferred male dermatologist and females preferred female dermatologist, 142 (52.8 %) and 167 (66.5%), respectively. Only 14 (2.7 %) had no preference. As far as the experience with dermatological service was concerned, 273 (52.4%) had had one or more consultations, 225 (82.4%) had used the services for curative purpose, 91 (33.3%), 104 (38.1%) and 78 (28.6%) had used governmental, private and both facilities, respectively. Overall, 188 (68.9%) patients were satisfied, but of those who had availed themselves of the government services, 36 (42.3%) were not satisfied and 68 (24.9%) considered the waiting time too long.
Conclusion:
Dermatological services at the governmental facilities do not meet the expectations of the adolescent. Well-designed operational research studies on the appropriate sample, focusing on patients’ expectation and satisfaction with appropriate sample is required. Such studies will facilitate the work of the policy makers and service implementers and help them to develop appropriate human and other resources in order to tailor dermatologic services to the clients’ expectations.

20.  Psychosocial risk and protective factors of secondary school dropout in Luxembourg: the protocol of an exploratory case-control study 
BMC Public Health  2011;11:555.
Background
In Luxembourg, the extensive phenomenon of school dropout is a prime policy concern in the light of individual, social and economic consequences. Although the authorities report an overall decrease of the national dropout rate, the proportion of early school leavers who remain without any specific occupation is still alarming. Therefore, this study intends a shift of focus from system-inherent to individual factors, including mental health and family correlates, to provide a more comprehensive analysis of the dropout phenomenon.
Methods/Design
The objectives of this study are to investigate the type and prevalence of psychiatric disorders among school dropouts and to compare the findings with those by a matched control group of regularly enrolled students. Furthermore, family variables and socioeconomic status will be analysed, as they are factors likely to interfere with both educational attainment and mental health. A trained psychologist will use structured interviews and self-report forms to investigate for mental health issues, information on schooling, socioeconomic situation and family life. Controls will be matched for gender, age, school type and educational grade.
Discussion
As school dropouts face a serious risk of long term professional and social marginalization, there is an evident need for action. Identifying psychosocial risk and protective factors of school dropout will deliver solid insight on how to conceive public health strategies for young people who may need a more customized support to carry out their academic potential.

21.  Effort-Reward Imbalance at School and Depressive Symptoms in Chinese Adolescents: The Role of Family Socioeconomic Status 
Depression is a major mental health problem during adolescence. This study, using a sample of Chinese adolescents, examined the separate and combined effects of perceived school-related stress and of family socioeconomic status (SES) on the prevalence of depressive symptoms. A total of 1774 Chinese students from Grades 7–12 were recruited into our questionnaire survey. School-related stress was measured by the Effort-Reward Imbalance Questionnaire-School Version, family SES was assessed by a standardized question, and depressive symptoms were evaluated by the Center for Epidemiological Studies Depression Scale for Children. Multivariate logistic regression was applied, adjusting for age, gender, grade, smoking, alcohol drinking and physical activity. It was found that high school-related stress and low family SES were associated with elevated odds of depressive symptoms, respectively. The effect of school-related stress was particularly strong in low SES group. In adolescents with both high stress at school and low SES, the odds ratio was 9.18 (95% confidence interval = 6.53–12.89) compared to the reference group (low stress at school and high SES). A significant synergistic interaction effect was observed (synergy index = 2.28, 95% confidence interval = 1.56–3.32). The findings indicated that perceived school-related stress, in terms of effort-reward imbalance, was related to depressive symptoms in this sample of Chinese adolescents. The strong interaction with family SES suggests that health promoting efforts in school settings should be targeted specifically at these socially deprived groups.

22.  Nationwide Report on the Findings of Integrated School Health Screening Program in Iran 
Background:
Screening of students’ health problems could lead to timely prevention and control of many health disorders. This study aimed to determine the nationwide prevalence of common disorders through school health screening program in Iran
Methods:
This cross-sectional national screening program was conducted in 2007–2008 among first- and third-grade-students in primary schools, first-grade-students of middle and high schools of all provinces in Iran.
Results:
Data were obtained from 3,124,021 (81.9%) students reported from the whole country classified into 33 geographical zones. Of total students studied, 12.48% had weight abnormalities, 4.77% had visual disorders, 3.95 % had head lice, 2.24% had behavioral disorders, and 0.6% had hearing disorders. Among students studied, 0.4%, 0.7%, 0.4% and0.8% had endocrine, psychological, neurological and genitourinary disorders, respectively. In addition, 2.1%, 1.9%, 1.8%, 0.8%0.5%, 0.3% and 0.3% of students had ear, nose & pharynx disorder, anemia, skin & hair, cardiac, abdominal, vertebral and lung problems, respectively. In elementary schools, 57.6% of first-grade-students with at least one disorder were managed in outpatient settings and 6% of them were hospitalized for more investigation. Among third-grade-students of elementary schools, these values corresponded to 13.2% and 1.1%, respectively. Among first grade students of middle and high schools, this prevalence was 58.5% and 44.6% and 1.2% and 0.3% of students were hospitalized for more investigation.
Conclusion:
This integrated school screening program revealed a considerably high prevalence of health disorders among school students. These results might help health policy makers to design future health promoting programs.

23.  Race and Academic Achievement in Racially Diverse High Schools: Opportunity and Stratification 
Teachers College record (1970)  2010;112(4):1038-1063.
Background/Context
Brown v Board of Education fundamentally changed our nation's schools, yet we know surprisingly little about how and whether they provide equality of educational opportunity. Although substantial evidence suggests that African American and Latino students who attend these schools face fewer learning opportunities than their White counterparts, until now, it has been impossible to examine this using a representative sample because of lack of data.
Purpose/Objective/Research Question/Focus of Study
This study uses newly available data to investigate whether racially diverse high schools offer equality of educational opportunity to students from different racial and ethnic groups. This is examined by measuring the relative representation of minority students in advanced math classes at the beginning of high school and estimating whether and how this opportunity structure limits the level of achievement attained by African American and Latino students by the end of high school.
Setting
This study uses data from the Adolescent Health and Academic Achievement Study (AHAA) and its partner study, the National Longitudinal Study of Adolescent Health (Add Health), a stratified, nationally representative study of students in U.S. high schools first surveyed in 1994–1995.
Population/Participants/Subjects
Two samples of racially diverse high schools were used in the analysis: one with African Americans, Whites, and Asians (26 schools with 3,149 students), and the other with Latinos, Whites, and Asians (22 schools with 2,775 students).
Research Design
Quantitative analyses first assess how high schools vary in the extent to which minority students are underrepresented in advanced sophomore math classes. Hierarchical multilevel modeling is then used to estimate whether racial-ethnic differences in representation in advanced math have an impact on African American and Latino students’ achievement by the end of high school, relative to the Whites and Asians in the school. Specifically, we estimate the effects of Whites’ and Asians’ overrepresentation in sophomore-year math (or Latino or African American underrepresentation) within the school on students’ senior-year grades and their postsecondary enrollment.
Findings/Results
Findings show that schools vary in the extent to which African American and Latino students are underrepresented in advanced sophomore math classes. This pattern of racial inequality in schools is associated with lower minority senior-year grades and enrollment in 4-year postsecondary institutions, net of students’ own background.
Conclusions/Recommendations
Evidence consistently suggests that schools can play an active role in the provision of opportunities for social mobility or in the exacerbation of social inequality, depending on how they are structured. It is important to consider racial stratification within schools as a mechanism of inequality of educational opportunity.

24.  Factors contributing to school failure among school children in very fast developing Arabian Society 
Oman Medical Journal  2009;24(3):212-217.
Objectives
Education is one of the main foundations for the child’s development and also for national human resource development. Failure at school and grade retention is a serious concern among children, and their parents. The characteristics of school failure in Qatar have not been studied earlier. The aim of this study is to assess the presence of social, psychological, health and school related factors that cause school failure.
Methods
All students who had failed their grades and had to be retained and repeat the year from 35 randomly selected schools of all grades elementary, intermediate and high school were included in this study for academic years from 2003 to 2008. Each student was individually interviewed by a well-trained school social worker.
Results
The study was performed on a total 699 children who were classified as school failures. Social reasons include living with one parent 26.9%, parental divorce (27%) parents showing no interest in their child’s education and school system (41.6%), low income (19.3%), and smoking (19.6%). Frequent absence from school was a result in 33.3%; incomplete homework (45.9%) and teachers identified 63.7% of students to be hyperactive, inattentive and disruptive in classroom. Most frequent psychological disorders include examination phobia (68.8%), anxiety (49.4%), anger (32.5%), fear (43.2%) and learning disability (37.9%). The most prevalent health disorders included visual disorders (23.5%), asthma (14.9%), anemia (15.2%), and hearing deficiency (8.2%).
Conclusion
Psychological and health related factors were found to be more prevalent in students who failed a grade in school. The primary care pediatrician can play a key role by identifying students at high risk and providing early intervention.

25.  The Prevalence of Mental Disorders among the Homeless in Western Countries: Systematic Review and Meta-Regression Analysis 
PLoS Medicine  2008;5(12):e225.
Background
There are well over a million homeless people in Western Europe and North America, but reliable estimates of the prevalence of major mental disorders among this population are lacking. We undertook a systematic review of surveys of such disorders in homeless people.
Methods and Findings
We searched for surveys of the prevalence of psychotic illness, major depression, alcohol and drug dependence, and personality disorder that were based on interviews of samples of unselected homeless people. We searched bibliographic indexes, scanned reference lists, and corresponded with authors. We explored potential sources of any observed heterogeneity in the estimates by meta-regression analysis, including geographical region, sample size, and diagnostic method. Twenty-nine eligible surveys provided estimates obtained from 5,684 homeless individuals from seven countries. Substantial heterogeneity was observed in prevalence estimates for mental disorders among the studies (all Cochran's χ2 significant at p < 0.001 and all I2 > 85%). The most common mental disorders were alcohol dependence, which ranged from 8.1% to 58.5%, and drug dependence, which ranged from 4.5% to 54.2%. For psychotic illness, the prevalence ranged from 2.8% to 42.3%, with similar findings for major depression. The prevalence of alcohol dependence was found to have increased over recent decades.
Conclusions
Homeless people in Western countries are substantially more likely to have alcohol and drug dependence than the age-matched general population in those countries, and the prevalences of psychotic illnesses and personality disorders are higher. Models of psychiatric and social care that can best meet these mental health needs requires further investigation.
Seena Fazel and colleagues show, through a systematic review and meta-regression analysis, that homeless people in Western countries have a higher prevalence of alcohol and drug dependence and mental disorders.
Editors' Summary
Background.
In 2007, it was estimated that there were more than 1 million homeless people worldwide. The true magnitude of the problem is difficult to estimate with no internationally agreed definition for homelessness and with the different approaches taken by countries and organizations in counting homeless people.
What we do know is that this is a diverse group of people who have poorer physical and mental health than the general population, leading to premature death. We also know that addressing barriers to health care and behavioral interventions for alcohol and drug dependence and mental health problems in this population can lead to lasting health gains.
Why Was This Study Done?
Health care for the homeless is a major public health challenge. Public policy and health service development depend on reliable estimates of the prevalence (how common a particular characteristic, e.g., a disease, is in a specific group of people or a specific population) of illnesses. By using statistical methods, the researchers aimed to provide a quantitative synthesis of the available evidence on mental health problems in this population and explore reasons for the differences in reported prevalence rates of serious mental disorders between studies, neither which have been done previously.
What Did the Researchers Do and Find?
The researchers systematically searched for surveys that estimated the prevalence of mental disorders in homeless people. Their final sample of 29 studies included a total of 5,684 homeless individuals based in the US, UK, mainland Europe, and Australia. Their main finding was that the prevalences of serious mental disorders were raised compared with expected rates in the general population, and many orders of magnitude higher than age-matched community estimates for psychosis, alcohol dependence, and drug dependence. In addition, the analysis found that alcohol and drug dependence is the most common mental disorder in the homeless (compared to psychosis, depression, and personality disorder). Also, the prevalence estimates of psychosis were found to be as high as those for depression. This latter finding contrasts with community estimates and other “at risk” populations such as prisoners and refugees, where depression is more common. The authors found substantial variation in the prevalence rates for these various disorders, and demonstrated that participation rates were associated with these variations for psychosis, depression, and personality disorder and that studies conducted more recently reported higher rates of alcohol dependence.
What Do These Findings Mean?
This review raises a number of implications for health services for the homeless and research for this population. First, traditional models of service delivery, which focus on those with severe mental illness, may not meet the mental health needs of most homeless people who suffer from alcohol and drug dependence and personality disorder. Second, an integrated approach to treatment may be beneficial and should take into account mental health, alcohol and drug abuse, welfare, and housing needs. Finally, future research should include studies that follow a group over time to help us better understand the risks and pathways into (and out of) homelessness, particularly in non-Western populations where there appears to be a paucity of information.
