1.  Parental perceptions of weight status of their children 
ARYA Atherosclerosis  2013;9(1):61-69.
Understanding the knowledge, attitudes, and beliefs of parents is important for planning appropriately to control their children’s weight. We aimed to study these variables in parents of normal, underweight, overweight, and obese children.
This cross-sectional study targeted the parents of normal, underweight, overweight, and obese children, who were selected using multistage random sampling method. The parents’ knowledge, attitudes, beliefs, and behaviors about the weight status of their children, weight management, obesity, diet, lifestyle, and related psychosocial factors were evaluated using a validated questionnaire. The questionnaire, which had been validated, consisted of 12 demographic, 8 knowledge, 19 attitude and beliefs, and 25 behavior questions. Mean knowledge, attitude and beliefs, and behavior scores were compared across three subgroups of parents. Student’s independent t-test, ANOVA, and Kruskal-Wallis test were used to study the correlation between different demographic and socioeconomic factors, and the studied variables.
90% of parents were aware that obesity is a disease, and 92% knew that eating too much fast food would lead to obesity in children. Only 5% assumed that obese children are healthier than non-obese children. The mean scores of the three subgroups showed no significant difference in knowledge, attitude and beliefs, and behavior. Families with fathers, whose education level was higher than high school diploma, rated their children’s weight status as overweight or obese significantly less than families with fathers, whose education level was high school diploma or lower (8.5% vs. 16.5%, respectively, P = 0.014). Only 12% of parents tried to help their children lose weight at least once, and only 6% arranged sport activities for the family members. In 57% and 41% of families, the child, respectively, decided how much time was enough to watch TV, and how much chocolates and sweets to eat. 46% of children watched TV for more than 2 hours/day, and 49% of children watched TV while eating meals. The mean total score of boys’ parents was significantly lower than that of girls’ parents (P < 0.05). Families with low income, with no medical insurance, or not owning a house thought that the cost of registration in sport activities for children was too high (P < 0.03).
Some parents unreasonably rated the weight status of their children as overweight/obese. It is suggested that further studies be carried out to evaluate and improve parents’ knowledge, attitudes, and behaviors regarding their children’s weight.

2.  Is there any Relationship Between C-Reactive Protein Level and Complex Coronary Plaques in Patients with Unstable Angina? 
ARYA Atherosclerosis  2010;6(1):31-34.
Coronary artery disease is a leading cause of death in developed countries. On the other hand, increased level of CRP has been seen in atherosclerosis. According to this finding, we decided to conduct this study to assess the relationship between CRP and complex lesions of coronary arteries in patients with unstable angina.
In this analytical cross sectional study which was conducted in 2007 in Chamran hospital, samples were collected using simple sampling and included 80 patients who referred to the hospital due to angina pectoris, had the diagnosis of unstable angina and were candidates of angiography. At first, a questionnaire was filled for each patient including demographic factors and their medical history. Then a blood sample was taken to assess level of CRP, FBS, and lipid profiles. The results of angiographic studies were considered by three cardiologists and abnormal patients were classified into simple and complex groups according to Ambrose criteria. Data was analyzed using SPSS version 15, t-student and chi-square tests.
Mean age of samples was 58.27 ± 6.23 years old. Considering the risk factors, most simple and complex lesions happened in obese patients however the only significant difference was observed in BMI between two groups (P < 0.05). Mean level of CRP in the population under study was 6.05 ± 4 mg/dl which was 1.37 ± 2 and 8.01 ± 6 in simple and complex groups respectively (P < 0.05). CRP mean was significantly higher in the group with complex lesions, less than 1 mg/dl in simple lesion and more than 4 mg/dl in complex lesions.
According to our findings, there is a significant difference considering CRP level in unstable angina patients who have complex lesions compared with simples ones. As complex plaques are more susceptible to develop coronary events, patients with a higher probability of complicated lesions can be screened.
