Objective To explore epidemiological characteristics and risk factors of overweight/obesity among preschool children in Shunyi district, and to provide scientific basis of prevention and clinical intervention for obesity in children. Methods A total of 1 238 preschool children aged 3~7 were selected as participants from 5 kindergartens in Shunyi district via clustered-random sampling from September to November 2017. Weight and height of subjects were measured. A self-designed questionnaire was used to investigate risk factors of obesity in children, and related risk factors were analyzed by multivariate Logistic regression. Results Overweight and obesity rates of preschool children in Shunyi district were 13.3% and 15.2%,respectively.Multivariate Logisitic regression analysis showed that cesarean birth(OR=1.333, 95%CI:1.032~1.722),father overweight/obesity ((OR=1.723, 95%CI:1.293~2.295)), mother overweight/obesity (OR=1.617, 95%CI:1.234~2.119), fast eating (OR=1.403, 95%CI:1.125~1.748) were independent risk factors of overweight/obesity in preschool children. Average outdoor activity time more than 2 hours was protective factor for children overweight/obesity (OR=0.649, 95%CI:0.549~0.771). Conclusion Overweight/obesity in preschool children is caused by multiple factors. Comprehensive prevention and control measures with parents joined should be developed to reduce the incidence of overweight/obesity in preschool children.
