Abstract：Objective The aim of this study is to investigate the epidemic trends in overweight and obesity amongst children and adolescents in Qingdao City, and to analyze the age, period and cohort effects on the overweight and obesity rates. Methods In this study, we collected the students' physical examination data in Qingdao City from 2012 to 2021. The annual percentage change rate and average annual percentage change rate were calculated by using Joinpoint regression analysis. The impacts of age, period and cohort effects on the overweight and obesity rates were estimated by an age-period-cohort model. Results The average annual overweight and obesity rates in the children and adolescents from 2012 to 2021 were 16.46% and 19.18% respectively. Joinpoint regression analysis revealed that the overweight and obesity rates in the children and adolescentsshowed overall upward trends, with the average annual percentage change rates of 1.4% and 4.8% respectively, moreover, the overweight and obesity rates increased faster and faster with the increasing age. The age-period-cohort model displayed that overall the children and adolescents' overweight rate increased with the increasing age, while overall their obesity rate decreased with the increasing age. The period effect revealed that the risks of overweight and obesity showed fluctuating upward trends with time passing by. The RR value of overweight risk increased from 0.99 in 2012 to 1.14 in 2021, and the RR value of obesity risk increased from 0.94 in 2012 to 1.50 in 2021. The cohort effect manifested that the risk of overweight and obesity in the children and adolescents firstly increased rapidly, but the risk of overweight (RR=1.02) in the birth cohort in 2009 and the risk of obesity (RR=1.24) in the birth cohort in 2013 decreased slowly after reaching the peaks. Conclusion From 2012 to 2021, the overweight and obesity rates in the children and adolescents in Qingdao City showed overall upward trends, and the risks of overweight and obesity in the young birth cohort were at high levels, but there were slowly declining trends. We should pay attention to the management of high-risk groups and formulate corresponding public health policies so as to curb the growing trends of overweight and obesity among the children and adolescents.
