孕妇妊娠早期体质量指数对产程及新生儿体质量的影响

Influence of Body Mass Index in Early Pregnant Women on Labor Abnormalities and Neonatal Weights

目的探讨妊娠早期孕妇体质量指数对产程及新生儿体质量的影响。方法回顾性分析2010年1月～2012年6月在我院进行产前保健检查,最后住院分娩的256例单胎妊娠妇女,记录孕妇妊娠早期(孕10w)体质量、身高,计算该孕周的体质量指数,确定产程异常的判断标准。结果 256例产妇中,肥胖者72例,其中16例产程异常,15例巨大胎儿;非肥胖者184例,其中21例产程异常,12例巨大胎儿。比较两组在产程异常及巨大胎儿的发生率,差异有统计学意义(P<0.05)。结论孕妇早期肥胖是一种产程异常的高危因素,继而影响新生儿体质量。

Objective To investigate the influence of body mass index in early pregnancy women on labor abnormalities and neonatal weights. Methods 256 cases of singleton pregnant women were recuited in January 2010 to June 2012 in our hospital and were retrospectively analyzed. All of the cases were carried out prenatal heath care and hospital parturition. Body weight and height of pregnant women in early pregnancy （10 weeks pregnant） wererecorded to calculate body mass index , and to determine the criteria of labor abnormalities. Results of 256 cases of maternal, there were 72 cases （28. 12%） of obesity and 184 cases （71. 86%） of non-obesity. 16 cases of labor abnormalities and 15 cases of fetal macrosomia in the 72 cases of obesity, while 21 cases of labor abnormalities and 12 cases of fetal macrosomia in the 184 cases of non-obesity. Statistically differences are evident when Comparing the two groups in labor abnormalities （X^2 =4. 890,P=0.02） and the incidence of fetal macrosomia （X^2 =11. 235,P=0. 001）. Conclusion Early obesity of pregnant woman is one of the risk factors, which can affect labor process and neonatal weights.
