Objective: To explore the relationship between overweight, obesity and development of children aged 3 ~ 18 years in Jiangxi Province From 2017 to 2020, a cross-sectional survey was conducted among 36,009 children aged 3-18 years in Jiangxi Province, and the possible influencing factors of obesity and precocious puberty were studied by single factor Logistic regression with SPSS 26.0 software According to the development of BMIS, the correlation between BMI and development level was regressed by Logistic regression results 1. Among the multiple factors of obesity, gender, mother's educational level, one-child family with obesity, parents with diabetes, mother's menarche, birth weight, time spent eating out and exercising electronic products are the independent influencing factors of childhood obesity (P < 0.05) Among the multiple factors of PP, sex, obesity, mother's menarche, family's annual income, breastfeeding exercise are the independent influencing factors of children's PP (P < 0.05) 2. In the correlation between BMI and development of children of different ages, the OR values of PP in overweight and obese girls aged 3 ~ < 6 years and 6 ~ < 10 years were 1.545 (95% Cl: 0.588-4.062) 17.713 (95% Cl: 10.201-30.757) 2.263 (95% Cl: 1.568-3.265) 4.488 (95% Cl: 3.168-6.357), respectively. The OR values of PP in overweight and obese boys aged 3 ~ < 6 years and 6 ~ < 10 years were 0.724 (95% Cl: 0.372-1.410) 3.450 (95% Cl: 2.259-5.2) 0.964 (95% Cl: 0.568-1.587) 2.840 (95% Cl: 1.956-4.125), respectively The OR values of overweight and obese boys aged 10 ~ < 15 years and 15 ~ < 18 years were 0.981 (95% Cl: 0.372-2.586) 1.203 (95% Cl: 0.360-4.022) 0.254 (95% Cl: 0.061-1.054) 0.224 (95% Cl: 0.031-1.634), respectively 3. In the correlation between BMI and different developmental stages, the correlation between obesity and sexual maturation (B2-B5/G2-G4) increased to some extent in children aged 6 ~ < 10 years, and the risk was B5 (G4) respectively (P < 0.05)

Conclusion: (1) The prevalence of childhood obesity and PP was affected by living habits, family situation, diet structure and other factors (2) The risk of PP in children with obesity is more obvious in girls; There is no significant correlation between overweight or obesity and delayed sexual development in boys (3) Obesity is a risk factor of sexual development in children aged 6 ~ < 10 years.
