Abstract
Results: The standardized prevalence of overweight significantly increased from 12.75 to 14.2% (p < 0.01), and the prevalence of obesity significantly increased from 3.35 to 3.94% (p < 0.01) during the study period. In contrast to data from developed countries, the prevalence of obesity decreased with age in both boys and girls. The prevalence of obesity and overweight in boys was significantly higher than that in girls (p < 0.01). Interestingly, the prevalence of overweight and obesity in the urban area was also significantly higher than that in suburb area (p < 0.01). Conclusion: Over a 5-yr period, there was a significant increase in the prevalence of obesity in children and adolescents in Shanghai. The high percentage of overweight and obesity in the young age groups is of particular concern. Urbanization might be a causative factor for the increase in obesity prevalence in Chinese children in the Shanghai area.
