Association between food intake frequency and obesity among adolescent girls in Saudi Arabia.

The main objective of this study was to discover the association between the intake of certain foods and the occurrence of obesity among adolescent girls in Saudi Arabia. A cross-sectional multistage sampling method was conducted among girls aged 12-19 years in Jeddah, Saudi Arabia. The total sample was 512. Obesity was calculated based on the International Obesity Task Force standards. Findings revealed that obese girls were less likely to eat fruit, vegetables, meat, chicken and dairy products than non-obese girls, but the differences were not statistically significant. However, the risk of being obese was greater for those who consumed chocolates and sweets (odds ratio=1.57) and fast foods (odds ratio=1.35) more than three times a week. Thus, programs to promote a healthy lifestyle for schoolchildren should include appropriate intervention on changing dietary habits.
