Abstract
Objective
To study the prevalence of overweight and obesity among Iranian schoolgirls and to identify risk factors which lead to obesity.
Method
This cross-sectional study was conducted in 2002 and a sample of 1800 female students between 7–12 years old was obtained using a multistage cluster sampling method from Tehran. Height and weight were measured and related socioeconomic information was collected.
Results
The overall percent of overweight and obesity was 13.3% and 7.7% respectively. BMI (Body Mass Index) was directly and significantly (r=+0.28, P<0.001) correlated with increasing age. Physical activity was significantly different between obese and non-obese children. (P=0.03) Also, economical factors such as the type of school (private& public) were different in these children. (P=0.03) The statistical analysis of the data revealed a significant and inverse correlation (r=-0.03, P=0.04) between maternal education and occurrence of overweight and obesity in children.
Conclusion
The prevalence of overweight and obesity in young Iranian girls was high. Advanced age, lack of physical inactivity, low economical factors and maternal educational status could be risk factors for obesity in children.
