Abstract：Objective To investigate the changing trends and influencing factors for growth retardation-related obesity in Chinese children aged 7-12 years in 2010-2020, providing a basis for formulating physical health interventions for children. Methods The data of body height and body mass index were collected from 16 289 children aged 7-12 years in the China Family Panel Studies (CFPS) in 2010-2020, and the trends of growth retardation, obesity, and growth retardation-related obesity in 2010-2020 were analyzed and compared between different sexes and between urban and rural areas. Results From 2010 to 2020, the overall rates of growth retardation and growth retardation-related obesity among children aged 7-12 years in China showed a declining trend (P<0.05). By gender and urban-rural classification, the overall obesity rate from 2010 to 2020 showed an increasing trend in all groups except for the rural male and female children groups, the rural children group, and the female children group (P<0.05). The prevalence rates of growth retardation, obesity, and growth retardation-related obesity in male children were significantly higher than those in female children, and similarly, these indicators were also significantly higher in rural children compared to urban children (P<0.05). Urban/rural residence, age, sex, and year were influencing factors for growth retardation and growth retardation-related obesity in children aged 7-12 years (P<0.05). Conclusions The prevalence of growth retardation, obesity, and growth retardation-related obesity among Chinese children aged 7-12 years shows gender and urban-rural disparities, which highlights the needs for targeted interventions for boys and children in rural areas.
