Abstract:Abstract: OBJECTIVE To understand the current prevalence of overweight/obesity among children aged 6~12 and explore the economic indicators influencing overweight/obesity during this period, in order to provide a theoretical basis for research on childhood obesity prevention measures. METHODS 3 685 children aged 6~12 from the 2020 China Family Panel Studies (CFPS) survey were selected for this study. Height, weight, BMI data were used along with family and economic questionnaires to analyze the factors influencing overweight/obesity among 6~12 years old children using binary logistic regression. RESULTS The prevalence of overweight/obesity among the 3 685 children in this study was 32.4% , with 37.4% in boys and 26.6% in girls. Significant differences in gender, age, father ’ s education level, mother ’ s education level, monthly food expenses, family food expenditures, and children ’ s education expenses were found between overweight/obese and non-overweight/obese children (χ 2 =48.531, 11.193, 32.659, 9.050, 9.016, 15.293, P<0.05). Logistic regression analysis indicated that gender, mother ’ s education level, monthly food expenses, and children ’ s education expenses were significant factors associated with overweight/obesity in children. CONCLUSION The prevalence of overweight/obesity among Chinese children aged 6~12 is 32.4% , with boys higher than girls. Gender, mother ’ s education level, monthly food expenses, and children ’ s education expenses are factors related to overweight/obesity in children.
