目的:妊娠期体重增加与妊娠期糖尿病的相关性以及其对妊娠结局的影响。方法:通过对622例产检孕妇进行问卷跟踪调查,收集孕产妇的一般人口学信息、孕产史、孕期体重(孕早、中、晚3个时期)、血糖值、血压值及分娩期情况,回收有效问卷542份,按GDM诊断标准分为正常组(191例)和GDM组(351例)。结果:两组孕妇以汉族占绝大多数,分别占98.4%和96.0%。GDM组孕前BMI高于正常组(P=0.027),GDM组受教育程度高于正常组(P=0.002),子痫前期和妊娠期高血压发病率均较低。将孕前体重按正常、超重和肥胖进行分组,在孕前体重正常组中孕期前半段每周体重增加与患GDM的风险具有相关性(P<0.05),孕期增重太多会增加剖宫产率,而未发现孕期增重对婴儿出生体重有影响。结论:孕妇应合理增加体重,使妊娠期体重增加在科学范围内。
Aims: Correlation between weight gain during pregnancy and gestational diabetes mellitus and its effect on pregnancy outcome. Methods: Sixty-two pregnant women with birth control were surveyed by questionnaire, general demographic information, pregnancy history, weight during pregnancy (early, middle, late pregnancy), blood glucose, blood pressure and delivery period were collected. 542 valid questionnaires were collected and divided into normal group (n = 191) and GDM group (n = 351) according to GDM diagnostic criteria. Results: The two groups of pregnant women accounted for the vast majority of Han people, accounting for 98.4% and 96.0%. The BMI in GDM group was higher than that in normal group (P = 0.027). The education level in GDM group was higher than that in normal group (P = 0.002). The incidence of preeclampsia and gestational hypertension was lower in GDM group. Weight before pregnancy will be normal, overweight and obesity groups, normal weight group before pregnancy, weekly weight gain during the first half of the risk associated with GDM (P <0.05), too much weight during pregnancy will increase cesarean section rate , But did not find that weight gain during pregnancy had an impact on the birth weight of infants. Conclusion: Pregnant women should be reasonable to increase body weight so that pregnancy weight gain in the scientific context.
