目的 评价孕期体重增长与妊娠糠尿病(GDM)和巨大儿的关系,对孕期体重增长的合适范围提出建议。方法 选择我院产科登记的GDM孕妇73例作为研究组,以同期无并发症的孕妇73例作为对照组,定期检查至分娩。结果 孕前和分娩前平均体重,孕前超重型和肥胖型人数,孕期体重增长≥20kg的人数GDM组多于对照组,2组比较,差异有显著性(P<0.05,P<0.01);体重增长>15 kg巨大儿发生GDM组为28.57％(14/49),对照组为9.38％(3/32),2组比较,差异有显著性(P<0.05);体重增长≤15kg巨大儿发生GDM组为0,对照组为4.62％(3/65);孕期对照组平均体重增长14.44kg,GDM组平均体重增长18.20kg。结论 孕前体质指数增大与GDM发生有关;孕期的体重超增与巨大儿发生有关;孕妇的体重增长>15 kg巨大儿发生明显增加,故建议整个孕期体重增长的合适范围应控制在10～12.5kg。
Objective To evaluate the relationship between weight gain during pregnancy and gestational diabetes mellitus (GDM) and macrosomia, and to make recommendations on the appropriate range of weight gain during pregnancy. Methods 73 cases of GDM pregnant women registered in obstetrics and gynecology department of our hospital were selected as the study group. 73 pregnant women with no complications in the same period were selected as the control group, and were examined regularly until delivery. Results Before pregnancy and before delivery, the average body weight, the number of overweight and obesity before pregnancy, and the number of people with body weight gain ≥20kg during pregnancy were more in GDM group than those in control group. The difference was significant (P <0.05, P <0.01) The incidence of GDM group was 28.57% (14/49) in macrophages compared with 9.38% (3/32) in control group, and there was significant difference between the two groups (P <0.05) Group 0, control group was 4.62% (3/65); pregnant control group average body weight increased 14.44kg, GDM group average body weight increased 18.20kg. Conclusion The increase of body mass index before pregnancy is related to the occurrence of GDM. Excessive weight gain during pregnancy is related to the occurrence of macrosomia. The weight gain of pregnant women> 15 kg is obviously increased. Therefore, it is suggested that the appropriate range of weight gain during pregnancy should be controlled at 10-12.5 kg.
