孕期体质量增长与新生儿出生体质量的相关性研究

Correlation analysis between body mass increase during pregnancy and neonatal body mass

目的分析孕期体质量的增加与新生儿出生体质量、分娩方式及并发症的关系。方法选取2013年6月-2014年10月医院足月单胎妊娠孕妇（37-41周）730例。根据孕期体质量增加程度分为低体质量组（A组）210例、正常体质量组（B组）302例和超体质量组（C组）218例。收集孕妇临床资料,包括姓名、年龄、孕前身高、体质量、月经史、孕产史等,并对3组资料进行比较。结果新生儿体质量与孕妇孕前体质量指数、孕期体质量增加呈正相关（r=0.352、0.315,P〈0.05）。3组各指标间比较差异均有统计学意义（P〈0.05）。结论孕期体质量增加和新生儿出生体质量有关,根据个体差异不同应合理进行营养补充,减少剖宫产率和巨大儿出生率。

Objective To analyze the correlation between body mass increase during pregnancy and neonatal body mass,the mode of delivery and complications. Methods From June 2013 to October 2014,730 cases of full-term （37 - 41 weeks） normal singleton mothers in our hospital were selected. According to the increase degree of pregnant body mass, they were divided into low weight group （group A） with 210 cases, normal weight group （group B） with 302 cases, super weight group （group C） with 218 cases. The clinical data of pregnant women were collected, including name, age, pre-pregnancy body mass,height,menstrual history,pregnancy history,and compared between the 3 groups. Results The neonatal body mass were positively correlated with pre-pregnancy body mass index（ BMI）, body weight gain during pregnancy （r = 0. 352,0. 315, P 〈 0. 05）. The differences of 3 groups were statistically significant differences （ P 〈 0.05 ）. Conclusion The pregnancy weight gain is related to neonatal birth weight. So the pregnant woman should be reasonable nutritional supplements according to the individual differences, in order to reduce the cesarean section rate and huge birth rate.
