Overweight and obesity trends in Copenhagen schoolchildren from 2002 to 2007.
OBJECTIVE
The purpose of this study is to monitor the prevalence trend in overweight and obesity among Copenhagen schoolchildren from the school years 2002 to 2007.


METHODS
Copenhagen community health service doctors conducted routine examinations at school entry (ages 5-8 years) and exit (ages 14-16 years). Body mass index (kg/m²) of 33,245 schoolchildren was calculated. The prevalence of overweight (including obesity) and obesity was classified using the International Obesity Task Force definitions.


RESULTS
From 2002 to 2007, although the prevalence of overweight (including obesity) in young girls decreased from 17.8 to 15.9%, the trend was non-significant. In young boys, the trend slightly decreased, and the prevalence fell from 14.0 to 11.6%. In adolescent girls, the prevalence varied considerably and increased from 22.7 to 25.4% without a discernable trend. In adolescent boys, the trend slightly increased, and the prevalence rose from 15.8 to 18.9%. There were no significant changes in the prevalence of obesity.


CONCLUSIONS
In contrast to the preceding decades, we identified a potential stagnation in the obesity epidemic among children but a continuing increase among adolescents. It remains critical to continue monitoring and to increase preventive measures to reduce the prevalence of overweight and obesity.
