Insights
Childhood obesity prevalence in France has stabilized between 2000 and 2007. The National Nutrition and Health Program (PNNS) may have contributed to this positive trend in 7-9-year-old children.
Area of Science:
- Pediatric Endocrinology
- Public Health Nutrition
- Epidemiology
Background:
- Global rise in childhood obesity necessitates effective public health interventions.
- The French National Nutrition and Health Program (PNNS) was launched in 2001 to combat this trend.
- Monitoring childhood overweight and obesity is crucial for evaluating public health strategies.
Purpose of the Study:
- To assess changes in overweight and obesity prevalence among 7-9-year-old French children.
- To evaluate the impact of the PNNS on childhood body mass status.
- To compare prevalence data from 2000 and 2007.
Main Methods:
- Cross-sectional study utilizing a 2007 protocol comparable to 2000 data.
- Random selection of primary schools and classes across 11 French school districts.
- Standardized measurement of height and weight, with parental lifestyle questionnaires; data analyzed using International Obesity Task Force cut-offs and direct standardization.
Main Results:
- Overweight prevalence was 15.8% (2.8% obesity) in 2007, versus 18.1% (3.8% obesity) in 2000.
- The observed differences in prevalence between 2000 and 2007 were not statistically significant.
- Children of higher socioeconomic status (manager/white collar) had a significantly lower risk of overweight or obesity.
Conclusions:
- The study indicates a stabilization of overweight and obesity rates in 7-9-year-old French children from 2000 to 2007.
- The PNNS may have played a role in achieving this stabilization.
- Socioeconomic factors continue to be associated with childhood body mass status.
Objective:
Over the past several decades, the prevalence of childhood obesity has increased worldwide. In France, the National Nutrition and Health Program (PNNS), implemented in 2001, was aimed at stopping this increase. The purpose of our study was to monitor changes in prevalence of overweight and obesity in 7-9-year-old children in France since the PNNS was set up.
Methods:
A cross-sectional study was conducted in 2007 in France based on a comparable protocol used in 2000. Primary schools were randomly selected in 11 out of 26 administrative school districts. In each of these schools, two classes were randomly selected. All children from these classes were included. Weight and height were measured by nurses or physicians belonging to the French educational system. A lifestyle self-administered questionnaire was completed by the parents. International Obesity Task Force cut-offs were used to define body mass status. Direct standardization was used to enable a comparison between 2000 and 2007.
Results:
In 2007, the prevalence of overweight was 15.8%, including 2.8% obesity, compared with 18.1% and 3.8%, respectively, in 2000. Differences between 2000 and 2007 did not reach statistical significance. In both years, the risk of being overweight or obese was significantly lower for children whose parents' occupation was that of manager or white collar rather than the other, less-privileged occupational categories.
Conclusion:
Our study demonstrates stabilization of the prevalence of overweight and obesity in 7-9-year-old children in France between 2000 and 2007. It is possible that the PNNS may be partly responsible for this stabilization.
