BACKGROUND: To determine the prevalence of overweight and obesity among a sample of middle class junior high
school students in a district of Tehran and its association with certain demographic and dietary factors this study was
carried out.
METHODS: Weight, height, waist and hip circumferences were measured and information on two-day food intake and
demographics on 398 students aged 10-15 years from district 6 in Tehran were collected.
RESULTS: Prevalence of overweight and obesity in the studied girls were 19%,6.5% and in boys were 14%, 13%, respectively.
There was an inverse relationship between numbers of siblings and BMI. Overweight/obese students,
bought snacks from school shops more frequently than other students did.
CONCLUSIONS: Findings showed that the high prevalence of overweight/obesity can be related to the household size,
including the number of siblings and the pattern of snack purchase by the students.
