This is a prospective investigation

This is a prospective investigation of a Chinese birth cohort involving 181 380 children, who were born during 1993-1996 to mothers registered in a perinatal care surveillance system and whose weight and height were measured in 2000. Information on delivery mode and covariates was obtained from the surveillance system. Overweight was defined according to the International Obesity Task Force body mass index (BMI) cutoffs. Multivariable logistic regression was used to estimate adjusted odds ratios. Stratified analyses were done to test whether the association between caesarean section and overweight persisted across subgroups. The adjusted odds ratio of overweight for children born by caesarean compared with vaginal delivery was 1.13 [95% confidence interval {CI}: 1.08, 1.18]. The association persisted in subgroups stratified by gender, maternal education, maternal BMI, weight gain during pregnancy and child birthweight (all P values for interaction test ≥0.30). The adjusted odds ratio of overweight for children born by non-medically indicated caesarean delivery compared with vaginal delivery was 1.18 (95% CI: 1.00, 1.41). CONCLUSION: Caesarean delivery including non-medically indicated maternal request caesarean delivery compared with vaginal delivery modestly increases childhood overweight risk.

This is a prospective birth 380 children cohort study involved in 181, who is born mother in 1993 to 1996 register in a perinatal health monitoring system of the weight and height measurements in 2000. The information transfer mode and covariates are obtained from the monitoring system. Overweight is defined according to the lower limit of the body mass index (BMI) of the International Obesity Task group. Multivariate Logistic regression was used to estimate adjusted risk ratios. Analysis was made in the stratified is to test whether the Caesarean association between the parts and the persisted overweight in the subgroup. The adjusted risk ratio of overweight was (1.08 confidence interval (CI):, 1.18) compared with caesarean's vaginal delivery was 1.13 (95% confidence interval). The association in subgroups persisted by maternal education stratified, maternal gender, BMI, body weight gain in pregnancy and childhood birthweight (all P values for interaction testing is more than or equal to 0.30). Adjusted risk ratios of overweight were born in children compared to non medically representing Caesarean with delivery of vaginal delivery was 1.18 (95% confidence interval: 1, 1.41). Conclusions: the delivery of caesarean including non medically indicated a request for delivery with an increased risk of caesarean maternal vaginal delivery to overweight for a mild childhood.
