[Overweight and dietary habits among adolescent: schoolchildren study in the department of Hauts-de-Seine]

Abstract

Several epidemiologic studies show in a concordant way that the prevalence of the overweight and that of obesity increase in France. Obesity is an important risk factor in public health. The main aim of the National Program of Nutrition and Health is to stop the increasing prevalence of childhood obesity. In this framework, we conducted a prevalence study among 1507 schoolchildren (boys: 51,6%; girls: 48,4%) aged from 11 to 17 years old. A self-questionnaire was used to collect information concerning the weight, height and diet. The findings show that 17,6% of collegians are either over weighted or obese, 7,7% of the girls and 10,0% of the boys are in overweight; 5,5% of the girls and 11,7% of the boys are obese, according to the French charts of body mass index (BMI). This study shows a decreasing frequency of the overweight with the age in both males and females: 28,9% at the 11 years old and 13,2% at the 17 years old. Preventive actions are needed at early stages to try to stop and, if possible, to reverse the present increase of overweight. In this context, the itinerant forum of health promotion carried out in the Hauts-de-Seine department with school doctors can play a determining part.
