306例巨大儿的影响因素分析

目的：探讨新疆医科大学第二附属医院南湖分院近五年巨大儿的影响因素,为控制巨大儿的发生提供依据.方法：将从2008年1月1日至2012年12月31日在新疆医科大学第二附属医院南湖分院分娩的出生体重≥4000 g的活产新生儿306例为巨大儿组,出生体重2500～3999 g的活产新生儿306例为正常体重新生儿组进行回归分析.结果：①孕前BMI、孕期体重增加、孕妇年龄及孕周与巨大儿的发生有关（P＜0.01）.②多元逐步Logistic回归分析得出：孕妇年龄、孕周、孕期体重增加、孕妇分娩次数是巨大儿发生的危险因素,胎儿性别为女性是巨大儿的保护因素.结论：孕前BMI与巨大儿的发生有关.孕期体重增加、孕妇年龄、孕妇分娩次数、孕周是巨大儿发生的危险因素等的增加值的逐渐变大,巨大儿发生的危险性是逐渐增加,胎儿性别女性为保护因素.
