Results The detection rate of overweight and obesity among students was 14.90%,and 18.00% in 2017 which was higher in boys than that in girls.In 5 years,the two relevance ratios were higher in urban areas than those in rural areas,boys than girls,and the average growth rate of overweight and obesity were higher in rural areas than those in urban areas.The detection rate of overweight in middle and high schools was higher than that in primary schools,and the detection rate of obesity in middle and primary schools was higher than that in high schools.The average growth rate of overweight and obesity in high school was the fastest,1.99% and 5.23% respectively.Using time series analysis,it was predicted that the detection rate of overweight and obesity among students in this district was 14.42% and 14.07% in 2022. Conclusion The detection rate of overweight and obesity among adolescents is on the rise in Tongzhou district,especially in 2016-2017.And the two relevance ratios were significantly higher than those in the past four years.Measures should be taken to reduce the two relevance ratios and control the average growth rate.
