Childhood obesity strongly increased in the 1990's. The systematic school medical and developmental examination of the 5-6-year-old children is an opportunity to study its prevalence. This cross-sectional study included a representative sample of 1,008 children living in the French Haute-Savoie area in 2008. The prevalence of obesity (grades 1 and 2 of the international standards) is 9.7%. The prevalence is 15.2% among children in disadvantaged areas vs 9.1% among the others, representing a relative risk of 1.7. Obesity prevalence does not differ according to the gender. Severe thinness (grades 2 and 3) affects only 1.0% of children. In multivariate analysis, only three factors are linked to obesity: having both parents originating from other countries than metropolitan France and Switzerland, bringing a snack at school for afternoon break, having a family history of overweight. Socioeconomic characteristics, lifestyle, nutrition and well-being at school do not appear to be linked to obesity in our study. The comparison with a first departmental study made in 2003 among children in seventh grade (12-year old), shows a stabilization of the prevalence of obesity among the 5-6-year-old Haute-Savoie children between 1998 and 2008, which is consistent with recent national studies.
