Eating habits appears to be an important determinant of dietary intake and may consequently influence overweight and obesity. Understanding the relationship between the nutritional status and eating habits is necessary for effective prophylaxis and intervention of overweight/obesity in adolescents. The purpose of this study is to analyze the association of some eating habits with overweight and obesity among adolescents at the age of 11-14 from 9 junior high schools in Hanoi city to help design a model for predicting overweight and obesity from eating habits. A case-control study was conducted on 222 overweight/obese adolescents and 616 normal-weight adolescents (according to International Obesity Taskforce standards, IOTF). Research results indicated that protective factors of overweight and obesity include snacking; snacking at least 2 hours before or after a main meal; consumption of milk and dairy products in snacks; sensory liking for fruit. Risk factors include sensory liking for fat, sensory liking for sweet, sensory liking for fast food, sensory liking for carbonated soft drinks, skipping breakfast, and snacking before bed. The best predictive model of overweight and obesity s built from logistic regression analysis including 8 of the above eating habits with AUC (Area Under the Curve) value of 0.931. Thus, eating habits are closely related to overweight and obesity among 11-14 year-old adolescents in Hanoi.
