目的:总结目前该院正常产前检查(产检)的不同体重指数孕妇妊娠期体重增长的情况,并对其妊娠结局进行分析,指出根据不同体重指数进行正确体重增长指导的重要性。方法:对2009年1月～2010年1月在该院检查及分娩的2 557例孕妇进行分析,按孕妇孕前体重指数(BMI)进行分组,计算出不同组别的孕期体重增长值,并与2009年Institute of Medicine(IOM)体重增长指南进行比较,得出超出指南建议体重的比率,并随访妊娠结局。结果:四组孕妇体重超出指南建议的比率分别为38.36%、40.77%、65.36%、63.64%。这些孕妇与正常孕妇相比,剖宫产率、妊娠期糖尿病(GDM)、妊娠期高血压疾病(HDCP)、产后出血的发生率均升高,差异存在统计学意义(P<0.05)。结论:妊娠期提供正确的体重增长指导有着重要的意义,可以减少不良的妊娠结局,并可以减少妇女及后代肥胖症的发生。
OBJECTIVE: To summarize the status of weight gain of pregnant women with different BMI during normal prenatal examination (birth control) and to analyze their pregnancy outcome. The importance of guiding correct weight gain according to different body mass index is pointed out. Methods: A total of 2 557 pregnant women examined and delivered in our hospital from January 2009 to January 2010 were analyzed and grouped according to body mass index (BMI) before pregnancy to calculate the weight gain values of different groups during pregnancy. The 2009 Institute of Medicine (IOM) guidelines for weight gain were compared to guide the recommended body weight ratio and follow-up pregnancy outcomes. Results: The recommended rates for pregnant women exceeding the guidelines in the four groups were 38.36%, 40.77%, 65.36% and 63.64% respectively. Compared with normal pregnant women, these pregnant women had higher rates of cesarean section, gestational diabetes mellitus (GDM), gestational hypertension (HDCP) and postpartum hemorrhage, with statistical significance (P <0.05). CONCLUSION: Guidance for providing correct weight gain during pregnancy is of great importance to reduce adverse pregnancy outcomes and to reduce the incidence of obesity among women and future generations.
