Methods A total of 301 healthy women with cesarean section and a matched control group of 301 women delivered vaginally were identified at three district-level hospitals in Shanghai from May 2001 to February 2003. Two groups were matched according to their medical indications for cesarean section. Their infants were assessed at delivery, 1 month, 6 month and 1 year after birth. Results The incidence of neonatal complications and infant morbidities at all measurement occasions did not differ significantly between groups. Rehospitalization was found to be more likely among infants delivered by cesarean section in the first month after birth. However, there was no difference between two groups in the incidence of rehospitalization in the first year after birth. Cesarean section was also associated with a higher risk of infant diarrhea （adjusted relative risk=1.25, 95% CI： 1.01, 1.56）. Conclusion Infants did not have health benefits from cesarean section if the pregnancy was at low risk.展开更多

Methods Pregnant women who attended health examination at three selected district hospitals were investigated from May 2001 to February 2003. Results Among 933 puerperas, the CS rate was 37. 62%. The top four indications for CS were fetal distress （36. 5%）, social factors （35.9%）, relative cephalopelvic disproportion （18.5%） and pregnancy complications （6.3%） respectively, The result of regression analysis showed that puerperas who were overweight before pregnancy, had no confidence in vaginal delivery and had macrosomia were more likely to have CS. Conclusion At present, the CS rate in Shanghai was rather high, The main indications for CS were fetal distress and social factors. The high CS rate was associated with the psychological factor and some demographic factors such as birth weight and puerperas＇ weight before pregnancy.展开更多
