目的 了解上海市闵行区常住居民足月新生儿出生体重的现况及其相关因素,为提高新生儿出生人口体质提供参考依据。 方法 收集2006年1月-2011年11月上海市闵行区居民健康档案系统中登记建卡的新生儿出生体重及相关信息进行研究。 结果 共有206 165例新生儿纳入本研究,出生体重均数及中位数分别为3 343 g、3 320 g。男女低体重儿比例分别为0.6%、0.9%;巨大儿比例分别为9.0%、5.1%。低体重比例、巨大儿比例、出生体重均数、孕周和母亲怀孕年龄在男女间差异有统计学意义(P<0.05)。性别、出生年份、孕周、母亲怀孕年龄、分娩方式、户口类型、母亲健康状况均对出生体重均数有影响(P<0.05)。 结论 新生儿出生体重影响因素众多,应有针对性的采取不同的措施加以改善和控制。
