目的分析母体孕前体质量指数(BMI)及孕期体质量增长与新生儿出生体质量的关系。方法回顾性分析单胎初产孕足月(孕周≥37周且≤42周)、无合并内科疾病的母体共1754例,其孕前体质量指数及孕期体质量增长与新生儿出生体质量进行比较分析。结果孕前BMI≥25 kg/m2及孕期体重增长≥14.9 kg分娩巨大儿发生率明显增高,差异有统计学意义(P<0.05)。结论母体孕前体质量指数及孕期体质量增长与新生儿出生体质量有关,应加强孕妇孕前及孕期体质量控制,以避免巨大儿的发生。
Objective To analyze the relationship between the body mass index (BMI) of pregnant women and the weight gain during pregnancy and the newborn birth weight. Methods Retrospective analysis of full-term single-fetus pregnancy (gestational age ≥37 weeks and ≤ 42 weeks), no complications of medical maternal total of 1754 cases of pre-pregnancy body mass index and pregnancy weight gain and birth weight of newborns comparative analysis. Results Pre-pregnancy BMI ≥ 25 kg / m2 and pregnancy weight gain ≥ 14.9 kg The incidence of maternal children was significantly increased, the difference was statistically significant (P <0.05). Conclusions The body mass index of maternal pregnancy and body mass gain during pregnancy are related to birth weight. Neonatal pregnancy weight should be strengthened to avoid the occurrence of macrosomia in pregnant women.
