Abstract: Objective To investigate the prevalence of overweight and obesity among children aged 6-12 in Yichang City and analyze its influencing factors. Methods From 2021 to 2023,stratified sampling was used to select 6-12 year old children from 5 schools in Yichang City,District,and Township. A self-made general information questionnaire was used for the survey,and single factor and multiple factor logistic regression analysis were used to analyze the factors affecting overweight and obesity in children aged 6-12 years. Results A total of 750 survey questionnaires were issued in this study,and 731 were effectively collected,with an effective rate of 97.47%. Among them,96 people were overweight（13.13%） and 62 people were obese（8.48%）. There were statistically significant differences in the rates of overweight and obesity among children aged 6-12 years old with different gender,sleep time,exercise time,eating speed,weekly consumption of desserts,fried foods,beverages,number of vegetables and fruits consumption,and number of bedtime meals（all P<0.05）. Multivariate logistic regression analysis showed that male,insufficient sleep time,exercise time <1 hour/week,eating speed <8 minutes,consumption of desserts,fried foods,and beverages ≥3 times/week, consumption of fruits and vegetables <3 days/week,and bedtime meals ≥3 days/week were all risk factors for overweight and obesity in children aged 6-12（all P<0.05）. Conclusion The situation of overweight and obesity in children aged 6-12 in Yichang City is relatively severe. Gender,sleep time,exercise time,and dietary habits are risk factors that affect overweight and obesity in children aged 6-12 in Yichang City. Timely measures should be taken to urge children to exercise,improve dietary habits,and reduce the rate of overweight and obesity.
