目的:分析不同体重管理模式对妊娠结局的影响,为孕期保健提供依据。方法:对2009年3月以来门诊就医的1640例孕妇分为按体重增幅管理组716例(A组)和按体重指数管理组924组(B组),前瞻性研究两组体重管理模式对妊娠结局的影响。结果:两组孕妇在年龄、孕前体重、孕次、身高及产检次数上差异均无统计学意义(P>0.05)。两组早产发生率A组为10.20%,B组为6.49%,差异有统计学意义(P<0.01);足月低体重儿A组为4.61%,B组发生率为1.30%,差异有统计学意义(P<0.05);糖代谢异常率A组为17.32%,B组为13.10%,差异有统计学意义(P<0.01);两组巨大儿发生率A组为5.59%,B组为3.90%,差异有统计学意义(P<0.05);两组产后抑郁症A组为9.22%,B组为5.19%,差异有统计学意义(P<0.01);两组妊娠期高血压疾病、产后出血发生率的差异均无统计学意义(P>0.05)。结论:与按体重增幅管理相比,按体重指数管理可以减少早产、足月低体重儿、巨大儿、糖代谢异常和产后抑郁的发生。
OBJECTIVE: To analyze the effect of different weight management modes on pregnancy outcomes and provide the basis for health care during pregnancy. Methods: A total of 1640 pregnant women who were outpatient medical treatment since March 2009 were divided into 716 cases (group A) and 924 groups according to body mass index management group (group B). The prospective study on weight management of pregnant women The impact of the outcome. Results: The two groups of pregnant women in age, pre-pregnancy weight, pregnancy time, height and number of births was no significant difference (P> 0.05). The incidence of preterm birth in both groups was 10.20% in A group and 6.49% in B group, with a significant difference (P <0.01). The full-term low birth weight children in group A were 4.61% in group A and 1.30% in group B, with statistical differences (P <0.05). The abnormal rate of glucose metabolism was 17.32% in group A and 13.10% in group B, the difference was statistically significant (P <0.01). The incidence of macrosomia in group A was 5.59% in group A and 3.90%, the difference was statistically significant (P <0.05); two postpartum depression group A was 9.22%, B group was 5.19%, the difference was statistically significant (P <0.01); two groups of hypertensive disorders of pregnancy, There was no significant difference in the incidence of postpartum hemorrhage (P> 0.05). CONCLUSIONS: BMI-based management can reduce the incidence of preterm birth, term low birth weight infants, macrosomia, glycometabolism, and postpartum depression compared with weight gain management.
