Abstract:
Objective To explore the association between cesarean section and obesity in child and adolescent.Methods In this study,a total number of 42 758 primary and middle school students aged between 6 and 17 were selected,using the stratified cluster sampling method in 93 primary and middle schools in Hunan,Ningxia,Tianjin,Chongqing,Liaoning,Shanghai and Guangdong provinces and autonomous regions.Log-Binomial regression model was used to analyze the association between cesarean section and obesity in childhood or adolescent.Results Mean age of the subjects was (10.5±3.2) years.The overall rate of cesarean section among subjects attending primary or secondary schools was 42.3％,with 55.9％ in boys and,40.6％ in girls respectively and with difference statistically significant (P＜0.001).The rate on obesity among those that received cesarean section (17.6％) was significantly higher than those who experienced vaginal delivery (10.2％) (P＜0.001).Results from the log-binomial regression model showed that cesarean section significantly increased the risk of obesity in child and adolescent (OR=1.72,95％CI:1.63-1.82;P＜0.001).After adjusting for factors as sex,residential areas (urban or rural),feeding patterns,frequencies of milk-feeding,eating high-energy foods,eating fried foods and the levels of parental education,family income,parental obesity,physical activity levels,gestational age and birth weight etc.,the differences were still statistically significant (OR=1.48,95％ CI:1.39-1.57;P＜0.001).Conclusion The rate of cesarean section among pregnant women in China appeared high which may significantly increase the risk of obesity in child or adolescent.
