Abstract
Objective:To investigate the relationship between pre-pregnancy body mass index(BMI) and gestational weight gain(GWG) to pregnancy complications and adverse out-comes. Method:A total of 3541 singleton pregnant women received routine antenatal care in the Obstetrics and Gynecology Hospital of Fudan University from Feb. to Nov. according to BMI and different GWG. Multivariate Logistic regression was used to estimate the odds ratio and 95%confidence intervals ( CI ) . Result:The average weight of 3541 pregnant women increased by (16. 0±4. 9)kg,the average birth weight of newborns was (3341. 6±425. 9)g,the low and ex-cess birth weight accounted for 2. 1% and 5. 1% respectively. According to IOM recommended weight gain during pregnancy grouping, GWG is too low, too many groups of pregnant women and normal pregnant women is relatively large,cesarean section,premature birth rate difference was statistically significant(P<0. 05). Pregnancy overweight and obesity raised the risk of ges-tational diabetes mellitus (OR=2. 7,2. 3),gestational hypertension(OR=5. 4,7. 7),increased the number of giant newborns (OR=1. 6,8. 9 ),and the occurance of cesarean section(OR=1. 4,1. 7). GWG at too high will aslo contribute to the incidence of cesarean section(OR=1. 4, 1 . 7 ) . Conclusion:Overweight and obese women not only increase the risk of pregnancy com-plications,while increasing the risk of adverse outcomes. In obstetric care management,special attention should be paid to prenatal education and physical examination,it is recommended that women meet the appropriate body mass index after pregnancy. Pregnancy weight managementcan refer to IOM recommended weight gain for pregnant women weight control,the possible risk factors for appropriate intervention,in order to reduce the incidence of pregnancy complications, improve maternal and child outcomes. It is suggested to study large data and formulate guideline for Chinese women.关键词
