1.  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.

2.  Knowledge, attitude and practice of tobacco smoking by medical students in Riyadh, Saudi Arabia 
Annals of Thoracic Medicine  2010;5(3):145-148.
BACKGROUND:
Tobacco consumption is associated with considerable negative impact on health. Health professionals, including future doctors, should have a leading role in combating smoking in the community.
OBJECTIVES:
The aims of the study were to assess the prevalence of smoking among medical students of newly established medical colleges in Riyadh city, the capital of Saudi Arabia, as well as to assess students' attitude, practice and their knowledge on the risk factors of tobacco consumption.
METHODS:
A cross-sectional, questionnaire-based study of students from two medical colleges in Riyadh, Saudi Arabia was carried out. The questionnaire used was anonymous, self-administered and developed mainly from Global Adult Tobacco Survey (GATS).
RESULTS:
A total of 215 students participated in this study. Forty students (19%) indicated that they smoke tobacco at the time of the study. All of them were males, which raise the prevalence among male students to 24%. Tobacco smoking was practiced by males more than females (P value <0.0001) and by senior more than junior students (<0.0001). About 94% of the study sample indicated that smoking could cause serious illnesses. About 90% of the students indicated that they would advice their patients to quit smoking in the future and 88% thought that smoking should be banned in public areas. Forty-four students (20%) thought that smoking has some beneficial effects, mainly as a coping strategy for stress alleviation.
CONCLUSION:
Despite good knowledge about the hazards of tobacco consumption, about 25% of the medical students in this study continue to smoke. The main reported reasons should be addressed urgently by policy-makers. Special efforts should be taken to educate medical students on the effective strategies in managing stress during their study as they thought that tobacco smoking could be used as a coping strategy to face such a stress.

3.  Smoking behaviour and attitudes among adult Saudi nationals in Riyadh City, Saudi Arabia 
Tobacco Control  1996;5(3):215-219.
OBJECTIVE: To measure the smoking behaviour and attitudes among Saudi adults residing in Riyadh City, the capital of the Kingdom of Saudi Arabia. DESIGN: Cross-sectional survey. SETTING AND SUBJECTS: Primary health care centres (PHCCs) in Riyadh City were selected by stratified random sampling. Subjects resident in each PHCC catchment area were selected by systematic sampling from their records in the PHCCs; 1534 adults aged 15 years and older were interviewed during January to April 1994. MAIN OUTCOME MEASURES: Self-reported smoking prevalence; age of smoking initiation; daily cigarette consumption; duration of smoking; reasons for smoking, not smoking, and quitting smoking; intentions to smoke in the future; and attitudes toward various tobacco control measures. RESULTS: 25.3% of respondents were current smokers, 10.2% were ex-smokers, and 64.5% had never smoked. About 79% of all smokers started smoking between the ages of 15 and 30 years, and 19.5% before age 15. Significantly higher smoking prevalence and daily cigarette consumption were associated with being male, single, and being more highly educated. Relief of psychological tension, boredom, and imitating others were the most important reasons for smoking, whereas health and religious considerations were the most important reasons for not smoking among never-smokers, for quitting among ex-smokers, and for attempting to quit or thinking about quitting among current smokers. About 90% of all subjects thought that they would not smoke in the future. Physicians and religious men were identified as the most effective anti-smoking advocates by a much higher proportion of respondents (44%) than nurses, health educators, and teachers (each less than 5%). Health and religious education were generally cited as more effective in deterring smoking than tobacco control laws and policies. CONCLUSIONS: Cigarette smoking is prevalent among Saudi adults in Riyadh, particularly males, most of whom begin to smoke rather early in life and continue for many years. Health and religious education should be the cornerstone for any organised tobacco control activities, which are urgently needed to combat the expected future epidemic of smoking-related health problems.

4.  Predictors of smoking among male junior secondary school students in Riyadh, Saudi Arabia 
Tobacco Control  1996;5(1):26-29.
OBJECTIVE: To determine the prevalence and determinants of cigarette smoking among intermediate (junior secondary) schoolboys in Riyadh, Saudi Arabia. PARTICIPANTS: A sample of 1382 students (ages 12-19 years) in 45 classes randomly selected from 15 schools, using a two- stage stratified cluster sampling scheme. DESIGN: Students in the selected classes were requested to complete an anonymous questionnaire, under the supervision of trained interviewers. Univariate and multivariate statistical analyses of potential risk factors were performed. SETTING: Intermediate schools in Riyadh, Saudi Arabia. MAIN OUTCOME MEASURES: Association between current smoking and socio- demographic variables, history of smoking, age of smoking initiation, smoking behaviour among family members, knowledge of the harmful effects of smoking, and whether smoking is allowed in the presence of relatives and acquaintances. RESULTS: The prevalence of current smokers was 13.2% overall, ranging from 3.2% in those 12-13 years old to 31.1% in those aged 18-19. Some of the variables (nationality, father's education, and smoking allowed in the presence of parents or teachers) found to be associated with current smoking in a univariate analysis were no longer significantly associated with smoking in the multivariate analysis. By multivariate analysis, knowledge of the harmful effects of smoking, age, smoking allowed in the presence of friends or brothers, and previous smoking were statistically significant determinants of current smoking. CONCLUSIONS: Current health education activities against smoking should be continued and extended to the young population to further reduce the prevalence of smoking and its health consequences. Religious antipathy toward smoking should be emphasised in any local anti-smoking campaigns.

5.  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.

6.  The Global School Personnel Survey: a cross‐country overview 
Tobacco Control  2006;15(Suppl 2):ii20-ii30.
Teachers and administrators are role models for students, conveyors of tobacco prevention curricula, and key opinion leaders for school tobacco control policies. School teachers and administrators have daily interaction with students and thus represent an influential group for tobacco control. Data collected by the Global School Personnel Survey between 2000 and 2005 have shown that an alarming proportion of school personnel smoke cigarettes and use other forms of tobacco. At the regional level, current cigarette smoking is between 15% and 19% among school personnel included in this report around the world. The scarcity of tobacco‐free schools and the high level of smoking on school grounds by school personnel reported in this study indicate how seriously school practice and staff actions undermine the educational messages and other prevention efforts to reduce adolescent smoking prevalence. However, the majority of school personnel in most sites strongly agreed that they should receive specific training to help students avoid or stop using tobacco.

7.  Evaluation of factors influencing intention to quit smokeless and cigarette tobacco use among Nigerian adolescents 
Background:
Smokeless and cigarette tobacco use is becoming increasingly popular among Nigerian adolescents. This study aimed to evaluate predictors of intention to quit tobacco use among adolescents that currently use tobacco products in Nigeria.
Materials and Methods:
A total of 536 male and female high school students in senior classes in Benue State, Nigeria were enrolled into the cross-sectional study. The survey instrument was adapted from the Global Youth Tobacco Survey (GYTS) questionnaire.
Results:
Among adolescents with tobacco habits, 80.5% of smokeless tobacco users and 82.8% of cigarette smokers intended to quit tobacco use within 12 months. After adjustment, significant predictors of intention to quit cigarette smoking were parents’ smoking status (P<0.01), peers’ smokeless use status (P<0.01) and perception that smoking made one comfortable at social events (P<0.01). For intention to quit smokeless tobacco use, significant predictors after adjustment were parents’ smokeless use status, (P=0.03) perception that smokeless tobacco use made one more comfortable at social events (P=0.04) and perception of harm from smokeless use (P=0.02).
Conclusion:
This study demonstrates that the intention to quit smokeless and cigarette tobacco use is significantly predicted by perception about the societal acceptance of tobacco use at social events, parents and peers’ tobacco use status as well as the perception of harm from use of tobacco products. Providing social support may increase quit attempts among youth smokers.

8.  Prevalence and social environment of cigarette smoking in Cyprus youth 
BMC Public Health  2008;8:190.
Background
Tobacco use is the single most preventable cause of morbidity and mortality in humans. Limited data exist regarding the extent of the problem among Cyprus youth. We use the Global Youth Tobacco Survey to assess the prevalence of cigarette smoking among middle and high school students as well as the social environment in which this is taking place.
Methods
The survey was conducted by the Cyprus International Institute for the Environment and Public Health in association with Harvard School of Public Health. A two-stage cluster sample design was used to select a representative sample of students from middle and high schools registered with the Republic of Cyprus in 2005–2006. The study questionnaire consisted of 99 questions and participation in the survey was voluntary. Statistical analyses were performed taking into consideration the specific design of the study and the sample weights associated with each completed questionnaire.
Results
The prevalence of current smoking, defined as having smoked cigarettes on one or more days of the past 30 days, is 13% among boys and 7% among girls in middle schools, and 36% among boys and 23% among girls in high schools. Furthermore, 16% of middle school students and more than 24% of high school students that had never smoked indicated that they are likely to initiate smoking within the next year. Exposure to environmental tobacco smoke is also very high with 91% of students reporting being exposed to smoke in places outside home. In addition, more than 95% of current smokers reported that they had bought cigarettes in a store during the past month and were not refused cigarettes because of their age.
Conclusion
Smoking prevalence among Cyprus middle and high school students is high and there are indications of an increase in the prevalence of smoking among girls over the last few years. Susceptibility rates, exposure to second-hand smoke, and access to and availability of cigarettes to youth are also high and concerning. The present survey indicates that the problem of cigarette smoking among youth in Cyprus is significant and requires collective action immediately.

9.  Smoking pattern among female college students in Dammam, Saudi Arabia 
Background:
Smoking is the most important avoidable cause of premature morbidity and mortality in the world. The estimated annual death rate of 4.9 million people in 1999 is expected to rise to 10 million by the 2020s and 2030s, 7 million of which will occur in developing countries.
Aim:
The aim of the present study was to estimate the prevalence of smoking and assess its pattern among non-medical female college students in Dammam, Saudi Arabia.
Materials and Methods:
A cross-sectional study was conducted of 1020 female students selected from the literature and science colleges by multi-stage stratified random sampling technique with proportional allocation. Data were collected using a self-administered modified WHO Global Youth Tobacco Survey questionnaire.
Results:
Results revealed that occurrence of smoking among female college students was 8.6%. It was significantly higher among literature college students (12.1%) than among Science College students (3.4%). The mean age at which smoking started was 16 ± 2.4 years, with a minimum of 11 years. More than half of the students who smoked were cigarette smokers, while 43.2% were shisha smokers. There was a strong relationship between parents who smoked and daughters who smoked. The main motive for smoking was curiosity (44.3%), followed by relief of tension (26.1%).
Conclusions:
It may be concluded that smoking is increasing among female college students in Saudi Arabia. Accordingly, it is recommended that a preventive comprehensive health education program on smoking be initiated for females in middle schools, that stricter tobacco control measures be adopted by the government, and that anti-smoking clinics be established in colleges.

10.  Prevalence and correlates of tobacco use amongst junior collegiates in twin cities of western Nepal: A cross-sectional, questionnaire-based survey 
BMC Public Health  2008;8:97.
Background
College students are vulnerable to tobacco addiction. Tobacco industries often target college students for marketing. Studies about prevalence of tobacco use and its correlates among college students in Nepal are lacking.
Methods
A cross-sectional survey was carried out in two cities of western Nepal during January-March, 2007. A pre-tested, anonymous, self-administered questionnaire (in Nepali) adapted from Global Youth Tobacco Survey (GYTS) and a World Bank study was administered to a representative sample of 1600 students selected from 13 junior colleges by two-stage stratified random sampling.
Results
Overall prevalence of 'ever users' of tobacco products was 13.9%. Prevalence among boys and girls was 20.5% and 2.9% respectively. Prevalence of 'current users' was 10.2% (cigarette smoking: 9.4%, smokeless products: 6.5%, and both forms: 5.7%). Median age at initiation of cigarette smoking and chewable tobacco was 16 and 15 years respectively. Among the current cigarette smokers, 58.7% (88/150) were smoking at least one cigarette per day. Most (67.8%) 'Current users' purchased tobacco products by themselves from stores or got them from friends. Most of them (66.7%) smoked in tea stalls or restaurants followed by other public places (13.2%). The average daily expenditure was 20 Nepalese rupees (~0.3 USD) and most (59%) students reported of having adequate money to buy tobacco products. Majority (82%) of the students were exposed to tobacco advertisements through magazines/newspapers, and advertising hoardings during a period of 30 days prior to survey. The correlates of tobacco use were: age, gender, household asset score and knowledge about health risks, family members, teachers and friends using tobacco products, and purchasing tobacco products for family members.
Conclusion
School/college-based interventions like counseling to promote cessation among current users and tobacco education to prevent initiation are necessary. Enforcement of legislations to decrease availability, accessibility and affordability of tobacco products and policies to change social norms of tobacco use among parents and teachers are necessary to curb the tobacco use among college students.

11.  Perceived Enforcement of School Tobacco Policy and Adolescents’ Cigarette Smoking 
Preventive medicine  2009;48(6):562-566.
Objectives
School tobacco use policies are part of a comprehensive strategy for preventing or reducing adolescent cigarette smoking. This study examines the relationship between perceived tobacco policy enforcement at the school level and smoking behaviors among students.
Methods
21,281 middle and high school students of 255 schools in the 2006 Oregon Health Teens Survey. Multilevel logistic regression was conducted, using a school-level policy enforcement measure based on aggregated student reports, and individual-level characteristics (e.g., age, gender, cigarette smoking before age 12, personal beliefs about smoking) as predictors of past-30-day cigarette smoking behaviors (e.g., any smoking, daily smoking, heavy episodic smoking, smoking on school property).
Results
Higher levels of perceived enforcement of anti-smoking policy at the school level were inversely associated with the prevalence of past-30-day smoking behaviors, independent of individual-level predictors.
Conclusions
Stricter enforcement of school policies against tobacco use may help prevent or reduce adolescents’ cigarette smoking on and outside of school property.

12.  ACCEPTANCE OF PREMARITAL HEALTH COUNSELING IN RIYADH CITY, 1417H 
Background:
Health counseling before marriage can be a most worthwhile and satisfying aspect of preventive medicine. It is important in genetic diagnosis and the prevention of hereditary, sexually transmitted and other infectious diseases.
Objectives:
To determine the acceptance of the concept of Premarital Health Counseling (PMHC), and to identify some factors, which may efect this acceptance among Saudis who attend Primary Health Care Center in Riyadh, Kingdom of Saudi Arabia (KSA), 1417H.
Methods:
The present study is a cross-sectional one with a selected sample of Saudis who attended the Primary Health Care Centers in Riyadh during the year 1417H. A multistage sampling and equal allocation stratified sampling within was used to select 484 persons comprising an equal number of males and females, married and single above the age of 18 years. A pre-designed pre-tested questionnaire sheet was used to collect the required data, which were then tabulated and statistically analyzed.
Results:
The study indicated that 364 (75.2%) of the study population accepted the concept of Premarital Health Counseling. PMHC was positively affected by the advancing age, experience of marriage, educational level and well-understood Islamic-health related issues. Out f those who accepted the concept, 273 (75%) agreed on the exchange of PMHC certificates between couples to be married and 152 (42%) agreed on the implementation of legislation on PMHC. Also, 298 (82%) of them wanted PMHC to be confidential and 168 (46%) agreed to the concept despite its cost. As regards the location of PMHC, most of participants who agreed to PMHC would prefer it to be given at governmental establishments.
Recommendations:
The study recommended the implementation of PMHC in Saudi Arabia, since it was accepted by the study population. However, further studies should be carried out to determine the details to be incorporated in the PMHC, their implementation and legislation on demographic basis of the Saudi community. Also, a community health education program for PMHC has to be devised in collaboration with Islamic leaders.

13.  State-Level Tobacco Control Policies and Youth Smoking Cessation Measures 
Objective
Research on the effects of state-level tobacco control policies targeted at youth has been mixed, with little on the effects of these policies and youth smoking cessation. This study explored the association between state-level tobacco control policies and youth smoking cessation behaviors from 1991–2006.
Methods
The study design was a population-based, nested survey of students within states. Study participants were 8th, 10th, and 12th graders who reported smoking “regularly in the past” or “regularly now” from the Monitoring the Future study. Main cessation outcome measures were: any quit attempt; want to quit; non-continuation of smoking; and discontinuation of smoking.
Results
Results showed that cigarette price was positively associated with a majority of cessation-related measures among high school smokers. Strength of sales to minors’ laws was also associated with adolescent non-continuation of smoking among 10th and 12th graders.
Conclusions
Findings suggest that increasing cigarette price can encourage cessation-related behaviors among high school smokers. Evidence-based policy, such as tax increases on tobacco products, should be included as an important part of comprehensive tobacco control policy, which can have a positive effect on decreasing smoking prevalence and increasing smoking cessation among youth.

14.  Prevalence of and Susceptibility to Cigarette Smoking Among Female Students Aged 13 to 15 Years in Vietnam, 2007 
Preventing Chronic Disease  2009;7(1):A11.
Introduction
Recent reports show a sharp increase in smoking rates among girls. We describe prevalence of cigarette smoking and susceptibility to cigarette smoking among female students aged 13 to 15 years in Vietnam and examine the associated factors.
Methods
We used data from female secondary school students aged 13 to 15 years (grades 8-10) from the 2007 Global Youth Tobacco Survey that was conducted in 9 provinces in Vietnam. We used multivariate logistic regression analysis to determine associations between independent variables with smoking status and susceptibility to smoking.
Results
Prevalence of cigarette smoking among girls was 1.2% (95% confidence interval [CI], 0.9-1.5), and 1.5% (95% CI, 1.2-1.9) of girls were susceptible to smoking. Having friends who smoke was the strongest predictor of both smoking status and susceptibility to smoking. Attendance at school classes that described the harmful effects of smoking had significant effects in reducing cigarette smoking. Girls who were exposed to billboard cigarette advertising were more likely to be susceptible to smoking than were those who had not seen advertisements.
Conclusion
Our findings highlight the need for pursuing school-based intervention programs in Vietnam and for countering tobacco advertising and marketing practices that target young women.

15.  Comparison of Cigarette and Water-Pipe Smoking By Arab and Non–Arab-American Youth 
Background
Water-pipe smoking is a rapidly growing form of tobacco use worldwide. Building on an earlier report of experimentation with cigarette and water-pipe smoking in a U.S. community sample of Arab-American youth aged 14–18 years, this article examines water-pipe smoking in more detail (e.g., smoking history, belief in harmfulness compared to cigarettes, family members in home who smoke water pipes) and compares the water-pipe–smoking behaviors of Arab-American youth with non–Arab-American youth in the same community.
Methods
A convenience sample of 1872 Arab-American and non–Arab-American high school students from the Midwest completed a 24-item tobacco survey. Data were collected in 2004–2005 and analyzed in 2007–2008.
Results
Arab-American youth reported lower percentages of ever cigarette smoking (20% vs 39%); current cigarette smoking (7% vs 22%); and regular cigarette smoking (3% vs 15%) than non–Arab-American youth. In contrast, Arab-American youth reported significantly higher percentages of ever water-pipe smoking (38% vs 21%) and current water-pipe smoking (17% vs 11%) than non–Arab-American youth. Seventy-seven percent perceived water-pipe smoking to be as harmful as or more harmful than cigarette smoking. Logistic regression showed that youth were 11.0 times more likely to be currently smoking cigarettes if they currently smoked water pipes. Youth were also 11.0 times more likely to be current water-pipe smokers if they currently smoked cigarettes. If one or more family members smoked water pipes in the home, youth were 6.3 times more likely to be current water-pipe smokers. The effects of ethnicity were reduced as a result of the explanatory value of family smoking.
Conclusions
Further research is needed to determine the percentages, patterns, and health risks of water-pipe smoking and its relationship to cigarette smoking among all youth. Additionally, youth tobacco prevention/cessation programs need to focus attention on water-pipe smoking in order to further dispel the myth that water-pipe smoking is a safe alternative to cigarette smoking.

16.  Changes in Exposure to Secondhand Smoke Among Youth in Nebraska, 2002–2006 
Preventing Chronic Disease  2008;5(3):A84.
Introduction
Secondhand smoke is a major cause of morbidity and mortality. It has been associated with serious health problems in both children and adults. Efforts to reduce exposure to secondhand smoke in Nebraska have included programs to prevent tobacco use among young people and campaigns for smoke-free workplaces and homes. Despite these interventions, young people continue to be exposed to secondhand smoke at an unacceptably high rate. The objective of this study was to examine the extent to which Nebraska public middle and high school students were exposed to secondhand smoke in 2002 and 2006, to evaluate factors associated with this exposure, and to propose interventions.
Methods
The Nebraska Youth Tobacco Survey was administered in 2002 and 2006 to a representative sample of students from public middle and high schools. All students who chose to participate completed an anonymous, self-administered survey that included questions on demographics, tobacco use, tobacco-related knowledge and attitudes, and exposure to secondhand smoke. Data were weighted to account for nonresponses at both student and school levels and to ensure generalizability of the estimates for public school students in Nebraska according to their grade, sex, and race/ethnicity. This study analyzed a subset of responses on secondhand smoke exposure, which was defined as being in a room or vehicle during the previous 7 days with someone who was smoking cigarettes.
Results
Secondhand smoke exposure in a room, a vehicle, or both declined significantly among all students from 2002 (69.0%) to 2006 (61.3%). In both 2002 and 2006, students were significantly more likely to be exposed to secondhand smoke in a room than in a vehicle (64.4% vs 48.2% in 2002 and 56.9% vs 40.2% in 2006). Among racial and ethnic groups, only white students experienced a significant decline in exposure from 2002 (70.0%) to 2006 (61.4%). Girls were significantly more likely to be exposed to secondhand smoke in 2006 than were boys, and only boys experienced a significant overall decline in exposure from 2002 (69.3%) to 2006 (57.7%). Smoking behaviors and attitudes continued to influence secondhand smoke exposure from 2002 to 2006, although students experienced significant declines whether they were smokers or nonsmokers, and whether they lived with a smoker or not. Those with close friends who smoked and those who did not perceive secondhand smoke as harmful, however, did not benefit.
Conclusion
These data indicate reductions in exposure to secondhand smoke among Nebraska's middle and high school students, but exposure remains a problem, particularly in rooms. Adoption of a comprehensive statewide smoke-free policy will contribute to significantly reduced exposure to secondhand smoke among young people in public places, but other measures to address exposure in the home and private vehicles are needed or should be strengthened. These include physician counseling based on behavioral change theory to encourage cessation and home-based no-smoking rules, in addition to interventions that target minorities, who are disproportionately affected by secondhand smoke exposure. Evaluation of existing measures, such as programs to prevent tobacco use among young people and campaigns to collect pledges for smoke-free homes, will be required to determine their effectiveness in reducing exposure to secondhand smoke among youth in Nebraska.

17.  A Longitudinal Study of Exposure to Retail Cigarette Advertising and Smoking Initiation 
Pediatrics  2010;126(2):232-238.
OBJECTIVES
Accumulating evidence suggests that widespread advertising for cigarettes at the point of sale encourages adolescents to smoke; however, no longitudinal study of exposure to retail tobacco advertising and smoking behavior has been reported.
METHODS
A school-based survey included 1681 adolescents (aged 11–14 years) who had never smoked. One measure of exposure assessed the frequency of visiting types of stores that contain the most cigarette advertising. A more detailed measure combined data about visiting stores near school with observations of cigarette advertisements and pack displays in those stores. Follow-up surveys 12 and 30 months after baseline (retention rate: 81%) documented the transition from never to ever smoking, even just a puff.
RESULTS
After 12 months, 18% of adolescents initiated smoking, but the incidence was 29% among students who visited convenience, liquor, or small grocery stores at least twice per week and 9% among those who reported the lowest visit frequency (less than twice per month). Adjusting for multiple risk factors, the odds of initiation remained significantly higher (odds ratio: 1.64 [95% confidence interval: 1.06–2.55]) for adolescents who reported moderate visit frequency (0.5–1.9 visits per week), and the odds of initiation more than doubled for those who visited ≥2 times per week (odds ratio: 2.58 [95% confidence interval: 1.68–3.97]). Similar associations were observed for the more detailed exposure measure and persisted at 30 months.
CONCLUSIONS
Exposure to retail cigarette advertising is a risk factor for smoking initiation. Policies and parenting practices that limit adolescents’ exposure to retail cigarette advertising could improve smoking prevention efforts.

18.  Tobacco control policy and adolescent cigarette smoking status in the United States 
Nicotine & Tobacco Research  2009;11(7):875-885.
Introduction:
Tobacco policies that limit the sale of cigarettes to minors and restrict smoking in public places are important strategies to deter youth from accessing and consuming cigarettes.
Methods:
We examined the relationship of youth cigarette smoking status to state-level youth access and clean indoor air laws, controlling for sociodemographic characteristics and cigarette price. Data were analyzed from the 2001 to 2002 U.S. Health Behavior in School-Aged Children survey, a cross-sectional survey conducted with a nationally representative sample of 13,339 students in the United States.
Results:
Compared with students living in states with strict regulations, those living in states with no or minimal restrictions, particularly high school students, were more likely to be daily smokers. These effects were somewhat reduced when logistic regressions were adjusted for sociodemographic characteristics and cigarette price, suggesting that higher cigarette prices may discourage youth to access and consume cigarettes independent of other tobacco control measures.
Discussion:
Strict tobacco control legislation could decrease the potential of youth experimenting with cigarettes or becoming daily smokers. The findings are consistent with the hypothesis that smoking policies, particularly clean indoor air provisions, reduce smoking prevalence among high school students.

19.  Current iodine nutrition status and progress toward elimination of iodine deficiency disorders in Jazan, Saudi Arabia 
BMC Public Health  2012;12:1006.
Background
The term iodine deficiency disorders (IDD) refers to all the effects of iodine deficiency on growth and development in human and animal populations that can be prevented by correction of the iodine deficiency. The objective of this paper was to determine the iodine nutrition status among schoolchildren in the Jazan Region of the Kingdom of Saudi Arabia (KSA), by measuring urinary iodine concentrations and by clinical assessments of goiter rate.
Methods
A school-based cross-sectional survey was conducted in the Jazan region of southwestern KSA from May to November 2010. A total of 311 children, aged 6–13 years, drawn from 12 schools, were selected by a three-stage cluster random sampling method. Data on sociodemographic characteristics were collected using a structured questionnaire. Urine samples were collected and physical examinations were conducted to determine the presence or absence of goiter. Data were analyzed using SPSS version 17.0. Chi square and independent t-tests were used for proportions and mean comparisons between groups.
Results
Out of 360 selected children, 311 were examined. There were 131 males (42%) and 180 females (58%). The median urinary iodine concentration (UIC) of the study group was 421 μg/L. The study population proportion with UIC > 300 μg/L was 74% with a higher proportion among males and urban populations. The proportion of children with UIC of 100–300 μg/L was only 21% and was significantly higher among females compared with males (p < 0.001). Only about 3% of the children had a median UIC less than 50 μg/L. The prevalence of total goiter rate (TGR) among the sample of schoolchildren in Jazan was 11%, with significant variations between rural and urban populations and by gender.
Conclusions
The present study demonstrates a remarkable achievement in Universal Salt Iodization (USI) and IDD elimination goals in the Jazan area. However, UIC levels reflect excessive iodine intake and may put the population at risk of adverse health consequences like iodine-induced hyperthyroidism and autoimmune thyroid diseases.

20.  Tobacco use, exposure to secondhand smoke, and cessation counseling among medical students: cross-country data from the Global Health Professions Student Survey (GHPSS), 2005-2008 
BMC Public Health  2011;11:72.
Background
GHPSS is a school-based survey that collects self-administered data from students in regular classroom settings. GHPSS produces representative data at the national or city level in each country. This study aims to investigate the prevalence of tobacco use, exposure to secondhand smoke, and cessation counseling among medical students using the GHPSS data.
Methods
The Global Health Professions Student Survey (GHPSS) was conducted among 3rd year medical students in 47 countries and the Gaza Strip/West Bank from 2005-2008 to determine the prevalence of tobacco use and amount of formal training in cessation counseling.
Results
In 26 of the 48 sites, over 20% of the students currently smoked cigarettes, with males having higher rates than females in 37 sites. Over 70% of students reported having been exposed to secondhand smoke in public places in 29 of 48 sites. The majority of students recognized that they are role models in society (over 80% in 42 of 48 sites), believed they should receive training on counseling patients to quit using tobacco (over 80% in 41 of 48 sites), but few reported receiving formal training (less than 40% in 46 of 48 sites).
Conclusion
Tobacco control efforts must discourage tobacco use among health professionals, promote smoke free workplaces, and implement programs that train medical students in effective cessation-counseling techniques.

21.  How do medical students in their clinical years perceive basic sciences courses at King Saud University? 
Annals of Saudi Medicine  2011;31(1):58-61.
BACKGROUND AND OBJECTIVES:
The inclusion of detailed basic science courses in medical school curricula has been a concern of students. The main objective of this study was to explore the attitudes of medical students towards basic sciences courses taught to them in the preclinical years and the applicability of these courses to current clinical practice.
DESIGN AND SETTING:
A cross-sectional survey was conducted during 2008-2009 among medical students in their clinical years at King Saud University, Riyadh, Saudi Arabia.
METHODS:
Thirty percent of all students (n=314) were randomly selected to receive a questionnaire designed to evaluate their opinions about course load, ability to recall information, value of practical sessions, availability of references and course guidelines, and the applicability of individual courses to clinical practice.
RESULTS:
Students identified anatomy and pathology as the courses most overloaded with content (76% and 70%, respectively). Half of the students felt they retained the most knowledge of physiology (50%), while less than a quarter of students (19%) felt they retained the most information from biochemistry coursework. The role of practical sessions in facilitating theoretical understanding was more evident in anatomy (69%). Physiology was perceived as the subject with the highest applicability to clinical practice (66%), while pathology (29%) was identified as the subject with the least practical application. Students became increasingly negative in their opinions about basic science courses as they progressed through their medical education.
CONCLUSION:
Current attitudes of medical students towards their basic science courses indicate a need to reform the curricula so as to maximize the benefit of these courses.

22.  Social, Psychological, and Environmental-Structural Factors Associated with Tobacco Experimentation among Adolescents in Shanghai, China  
Objective: To estimate the prevalence and social, psychological and environmental-structural determinants of tobacco experimentation among adolescents in Shanghai, China. Methods: We conducted a cross-sectional study based on a two-stage cluster sample design by using the Chinese version of the Global Youth Tobacco Survey (GYTS) to investigate smoking behavior among 19,117 students from 41 junior and senior high schools in Shanghai, China. The association between potential factors and tobacco experimentation were assessed using complex samples procedure logistic regression. Results: Of the 19,117 respondents, 10.5% (15.3% boys and 6.2% girls) reported the tobacco experimentation. The main social, psychological, and environmental-structural factors associated with tobacco experimentation were having close friends who smoke (AOR = 8.21; 95% CI: 6.49–10.39); one or both parents smoking (AOR 1.57; CI: 1.39–1.77); a poor school tobacco control environment (AOR 1.53; CI: 1.37–1.83); a high acceptance level of tobacco use (AOR 1.44; CI: 1.28–1.82); and a high level of media tobacco exposure (AOR 1.23; CI: 1.10–1.37). Peer smoking might contribute to smoking experimentation among girls (AOR 8.93; CI: 5.84–13.66) more so than among boys (AOR 7.79; CI: 5.97–9.94) and media tobacco exposure had no association with tobacco experimentation among female students. Conclusions: Social, psychological, and environmental factors are closely associated with tobacco experimentation among adolescents. Prevention programs aimed at reducing teen tobacco experimentation should be conducted at home and school with support by parents, peers and teachers. Our findings should prove useful for future development of intervention strategies among adolescents in Shanghai, China.

23.  Prevalence and Determinants of Waterpipe Tobacco Use among Adolescents in Oman 
Objective:
To assess the prevalence and determinants of waterpipe use among school-going adolescents in Oman.
Methods:
A cross-sectional, school-based study was conducted in 2003 involving 9 regions of Oman, as part of the Global Youth Tobacco Survey. Participants were requested to complete an anonymous questionnaire containing demographic characteristics, current and previous use of waterpipe tobacco, attitudes towards cigarette smoking, parents’ and friends’ cigarette smoking habits. Proportions were used to calculate prevalence rates and logistic regression analysis to obtain odds ratio (OR) and 95% confidence interval (CI).
Results:
1,962 students participated of whom 1,005 (51.2%) were males. Eighty-eight percent were between 13 and 16 years of age. Five hundred and twenty-two (26.6%) reported ever smoking waterpipe tobacco while 189 (9.6%) were current users. Among males, 155 (15.5%) were current users while among females only 24 (2.6%) smoked currently. Study participants were more likely to use waterpipe if they had a parent or friend who smoked cigarettes. Adolescents were, however, less likely to use waterpipe tobacco if they believed that cigarette smoking was harmful to health. Students who were receiving 500 Baisas (US$ 1.3) or more per day pocket money were more likely to use waterpipe tobacco compared to those receiving less (OR 3.3, 95% CI 2.3 to 4.6). In multivariate analysis, the OR for males being a smoker of waterpipe tobacco compared to females was 4.46 (95% CI, 2.38 to 8.35); while the OR for most or all friends smoking cigarettes compared to non-smoking was OR 5.65 (95% CI 2.87 to 11.13). Study participants who perceived smoking as harmful to health were less likely to use waterpipe tobacco compared to those who did not believe smoking was harmful (OR 0.31, 95% CI 0.29 to 0.92) and those receiving 500 Baisas or more (OR 2.2, 95% CI 1.5 to 3.2).
Conclusion:
Waterpipe smoking among Omani adolescents is an emerging public health concern. Efforts to prevent adolescent smoking should be designed with knowledge of associated factors of such behaviour and should include all forms of tobacco.

24.  Students' perception of community disapproval, perceived enforcement of school antismoking policies, personal beliefs, and their cigarette smoking behaviors: Results from a structural equation modeling analysis 
Nicotine & Tobacco Research  2009;11(5):531-539.
Introduction:
School tobacco use policies are often considered to be part of a comprehensive approach to preventing or reducing adolescent cigarette smoking. However, little is known about the relationships between such policies and adolescents’ smoking behaviors or the mechanisms by which any such influence may occur. The present study tested a conceptual model that specifies possible direct and indirect relationships among community norms, school antismoking policies, adolescents’ personal smoking beliefs, and cigarette smoking behaviors.
Methods:
This study used data from 17,256 middle and high school students who participated in the 2006 Oregon Health Teens Survey.
Results:
Structural equation modeling indicated that perceived enforcement of school policy was directly and positively related to perceived community norms. In addition, adolescents’ personal beliefs appeared to mediate the relationship between perceived enforcement of school antismoking policies and past-30-day cigarette smoking. School policies, in turn, partially mediated the relationship between community norms and smoking beliefs.
Discussion:
The results of this study provide a better understanding of how community norms and school antismoking policies may affect adolescents’ cigarette smoking.

25.  Water-Pipe Tobacco Smoking Among Middle and High School Students in Arizona 
Pediatrics  2009;123(2):e282-e288.
BACKGROUND
Using a water pipe to smoke tobacco is increasing in prevalence among US college students, and it may also be common among younger adolescents. The purpose of this study of Arizona middle and high school students was to examine the prevalence of water-pipe tobacco smoking, compare water-pipe tobacco smoking with other forms of tobacco use, and determine associations between sociodemographic variables and water-pipe tobacco smoking in this population.
METHODS
We added items assessing water-pipe tobacco smoking to Arizona’s 2005 Youth Tobacco Survey and used them to estimate statewide water-pipe tobacco smoking prevalence among various demographic groups by using survey weights. We also used multiple logistic regression to determine which demographic characteristics had independent relationships with each of 2 outcomes: ever use of water-pipe to smoke tobacco and water-pipe tobacco smoking in the previous 30 days.
RESULTS
Median age of the sample was 14. Accounting for survey weights, among middle school students, 2.1% had ever smoked water-pipe tobacco and 1.4% had done so within the previous 30 days. Among those in high school, 10.3% had ever smoked from a water pipe and 5.4% had done so in the previous 30 days, making water-pipe tobacco smoking more common than use of smokeless tobacco, pipes, bidis, and kreteks (clove cigarettes). In multivariate analyses that controlled for covariates, ever smoking of water-pipe tobacco was associated with older age, Asian race, white race, charter school attendance, and lack of plans to attend college.
CONCLUSIONS
Among Arizona youth, water pipe is the third most common source of tobacco after cigarettes and cigars. Increased national surveillance and additional research will be important for addressing this threat to public health.
