Abstract: Objective To analyze the prevalence of overweight and obesity in infants and young children aged 6~23 months in poor areas of Hubei Province,and to explore the impacts of birth-related factors and early feeding types on overweight and obesity,in order to provide basis for prevention and control of overweight and obesity. Methods Multi-staged PPS sampling was adopted in 6 counties in Hubei Province,and caregivers of infants and young children were surveyed.Overweight and obesity were defined by the WHO sex-age based body mass index.Chi-square and multivariate Logistic regression were used to analyze the data. Results A total of 2 667 infants and young children were investigated,including 1 438 boys (53.92%) and 1 229 girls (46.08%).And 209(7.84%) were overweight and 151(5.66%) were obese.Infants and young children with birth weight over 4 000 g had higher prevalence of overweight,and boys had higher prevalence of obesity than girls (P<0.05).Cesarean delivery and early feeding types were associated with obesity (all P<0.05). Conclusion Overweight and obesity in infants and young children in poor areas of Hubei Province should not be overlooked.Boys and children who were cesarean deliveried or without breastfeeding in the first 6 months have higher prevalence of obesity and need positive attention and effective measures to prevent and control obesity.
