Abstract:
Objective:To investigate the associations between early life factors and the incidence of overweight and obesity and to provide a reference for childhood overweight and obesity prevention.
Methods:A total of 5 172 children aged 6-11 years from 5 primary schools in Guangzhou were enrolled using stratified random cluster sampling method. After two years follow up, 3 315 children were included in the final analysis. Questionnaire was used to collect children s early life factors. Height and weight were measured objectively at baseline and follow up.
Results:The incidence of overweight and obesity was 8.7% in children. After adjustment for confounders, results from the Logistic regression analysis showed that maternal pre pregnancy underweight was negatively associated with the incidence of childhood overweight and obesity( OR=0.54, 95%CI =0.38-0.76)( P <0.05). While excessive gestational weight gain during pregnancy( OR=1.55, 95%CI =1.14-2.10) and caesarean section ( OR=1.30, 95%CI =1.00-1.68) were positively associated with the incidence of childhood overweight and obesity( P <0.05).
Conclusion:Both excess gestational weight gain and caesarean section would increase the risk of the overweight and obesity of their offspring, while maternal pre pregnancy underweight would reduce the risk of childhood overweight and obesity.
