Objective To grasp the prevalence of overweight and obesity among children in a downtown area in Shanghai in the recent 5 years and provide the basis for further intervention. Methods In 2006, a total of 22 226 school-aged children were enrolled in the survey. In 2007-2009, a random cluster sampling method was used to establish monitoring points based on the survey of not less than 50% of the number of school-age students in the district. In 2010 A total of 1 771 school-age children (12.24% of the total number of school-age children) were measured by stratified random sampling. Results The overweight rates of boys in 2006-2010 were 14.85%, 14.20%, 14.25%, 14.43% and 17.91% respectively. The obesity rates were 22.11%, 20.63%, 21.75%, 19.16% and 29.73% respectively. The overweight rates of girls were 10.13% , 11.75%, 12.83%, 12.31% and 13.59%. The obesity rates were 9.95%, 10.68%, 12.44%, 11.06% and 15.53% respectively. The total overweight rates of males and females were 13.02%, 13.05%, 13.57% and 13.45% 15.75%, obesity rates were 15.87%, 15.97%, 17.35%, 15.43%, 22.64%.
