Aim: To assess time trends in overweight and obesity prevalence among 5-6-year-old children of Bordeaux city (France) over seven school years from 2004-2005 to 2010-2011.

Methods: For each year, all 5-6-year-old children from 63 of the 69 schools of Bordeaux were included: 2005, 2100, 2010, 1952, 2040, 2017 and 2111 subjects, respectively. Weight and height were collected by school doctors, and weight status was defined according to the age- and sex-specific body mass index cut-off points of the International Obesity Task Force (IOTF) for obesity and to the French age- and gender-specific child cut-off (close to the IOTF cut-off) for overweight including obesity.

Results: From 2004-2005 to 2010-2011, an overall decrease was observed in overweight including obesity (from 8.9% to 5.2%, p < 0.001) and obesity prevalences (from 2.8% to 1.4%, p = 0.046). Similar results were observed in non-low socio-economic status (SES) areas (p < 0.001), whereas the prevalence did not vary significantly in low-SES areas (p > 0.05).

Conclusion: Overweight prevalence has decreased between 2004 and 2011 in 5-6-year-old children from Bordeaux. However, the gap between low and non-low-SES areas has persisted during these years.
