Correlation analysis of the relationship between maternal weight gain,infant feeding style and childhood obesity

Objective To analyze the relationship between maternal weight gain during pregnancy and infant feeding methods and childhood obesity,and to provide reference for the development of measures to reduce childhood obesity.Methods A total of 951 children and their parents in the four kindergartens in our district were selected as subjects. The questionnaires were used to investigate the status of children and the pregnancy status of their mothers. The contents of the survey include: children's height,weight,infant feeding methods,etc. The contents of the survey included: children's height and weight and infant feeding methods,etc. Univariate analysis and multivariate logistic regression were used to analyze the relationship between childhood obesity and maternal weight gain and infant feeding patterns.Results A total of 951 questionnaires were distributed,and 940 valid questionnaires were returned. The recovery rate of the questionnaire was 98. 84%. The incidence of obesity among the children interviewed was 10. 00% (94/940). The results of univariate analysis showed that the incidence of obesity in children whose mothers had a weight gain of more than 15 kg during pregnancy was significantly higher than that in children whose mothers did not exceed 15 kg during pregnancy (P< 0. 05). The obesity rate of infants who were exclusively breastfed within 6 months of age was significantly lower than that of children without exclusively breastfeeding (P< 0. 05). The results of logistic regression analysis showed that maternal weight gain during pregnancy was greater than 15 kg,which was a risk factor for childhood obesity (P< 0. 05). Infants who were exclusively breastfed within 6 months of age were protective factors for childhood obesity (P< 0. 05).Conclusion The maternal weight gain more than 15 kg and the infant's exclusive breastfeeding within 6 months are the influencing factors of childhood obesity. It is necessary to guide pregnant women to properly control their weight gain and encourage the mother to adopt exclusive breastfeeding infant feeding methods,which is beneficial to reduce childhood obesity rate.
