目的:探讨孕前体重指数与孕期体重增长对妊娠结局影响。方法:回顾性分析2006年1月~2008年12月住院分娩的800例足月单胎初产妇的临床资料。结果:①孕前体重:孕前肥胖组、超重组的妊娠期高血压、子痫前期、子痫发生率、剖宫产率、阴道助产率、巨大儿发生率、高危新生儿发生率均高于正常体重组及消瘦组(P<0.05);GDM发生率孕前肥胖组高于正常体重组及消瘦组(P<0.05),孕前超重组高于消瘦组(P<0.05);产后出血率孕前肥胖组高于正常体重组及消瘦组(P<0.05);低体重儿发生率孕前消瘦组高于体重正常组(P<0.05)。②孕期BM I增幅:妊娠期高血压、子痫前期、子痫发生率、GDM发生率、剖宫产率、阴道助产率、巨大儿发生率孕期BM I增幅>6者高于增幅为4~6及<4者(P<0.05),增幅4~6者剖宫产率高于增幅<4者(P<0.05);增幅<4者的低体重儿发生率高于增幅4~6者及>6者,增幅4~6者高于增幅>6者(P<0.05)。增幅>6者的产后出血及高危新生儿发生率高于增幅4~6者(P<0.05)。结论:合理的孕前体重指数及孕期体重增幅利于优化妊娠结局。
Objective: To investigate the effect of pre-pregnancy body mass index and pregnancy weight gain on pregnancy outcome. Methods: The clinical data of 800 full-term single-born primiparae who were hospitalized for delivery from January 2006 to December 2008 were retrospectively analyzed. Results: ① Pre-pregnancy body weight: pre-pregnancy obesity group, overweight group of gestational hypertension, preeclampsia, eclampsia, cesarean section rate, vaginal delivery rate, the incidence of macrosomia, the incidence of high-risk neonates were higher than (P <0.05). The incidence of GDM in pre-pregnancy obesity group was higher than that in normal body weight group and emaciation group (P <0.05), and pre-pregnancy overweight group was higher than emaciation group (P <0.05) (P <0.05). The incidence of low birth weight children was significantly higher than that of normal weight group before pregnancy (P <0.05). Pregnancy BM I increase: gestational hypertension, preeclampsia, eclampsia, the incidence of GDM, cesarean section rate, vaginal delivery rate, the incidence of macrosomia during pregnancy BM I increase> 6 were higher than the increase of 4 (P <0.05). The rate of cesarean section increase of 4 ~ 6 was higher than that of the increase of 4 (P <0.05). The incidence of low birth weight infants <4 was higher than that of the increase of 4 ~ 6 And> 6, an increase of 4 to 6 were higher than the increase of> 6 (P <0.05). The incidence of postpartum hemorrhage and high-risk neonates with an increase of> 6 were higher than those with an increase of 4 ~ 6 (P <0.05). Conclusion: The reasonable pre-pregnancy body mass index and weight gain during pregnancy are conducive to optimizing the pregnancy outcome.
