绵竹市巨大儿危险因素的回顾性队列研究

A retrospective cohort study on risk factors of giant children in Mianzhu City

目的:调查绵竹市巨大儿发生情况及其危险因素。方法:通过孕妇保健手册、医院HIS系统电子病历收集2017年在绵竹市人民医院分娩的绵竹市籍孕妇及其新生儿资料,分析巨大儿(出生体重≥4000 g)的发生情况,并分析巨大儿发生的危险因素。结果:共纳入孕妇1113例,巨大儿发生率为4.32%。单因素分析结果显示,孕妇孕前体质指数(BMI)、体重、孕期增重超标、新生儿性别、孕周是巨大儿发生的危险因素。进一步采用Logistic回归分析结果显示,孕期增重超标、新生儿性别(男性)、孕周≥40周是巨大儿发生的危险因素。结论:加强孕期体重管理,控制孕期体重增长是进一步降低巨大儿发生率的重要举措。
