目的描述舟山市2002-2015年新生儿出生体重变化,分析不良出生结局的发生率及影响因素。方法利用舟山市电子医疗数据库,收集孕产妇及新生儿的相关信息,描述新生儿出生体重和不良出生结局发生率的变化趋势,采用多元Logistic回归分析其影响因素。结果 37 141例新生儿的平均出生体重为(3 388±462)g,低出生体重儿、巨大儿、早产的发生率分别为2.34%,9.42%和3.61%;高危妊娠(OR=1.80,95%CI:1.42~2.28)是低出生体重儿的危险因素;出生季节为夏季、秋季、母亲年龄<25岁、孕前消瘦等是巨大儿的保护因素。母亲孕前超重和肥胖是巨大儿的危险因素;母亲年龄<25岁是早产发生的保护因素。母亲年龄>30岁(OR=1.38,95%CI:1.19~1.60)、冬季出生(OR=1.24,95%CI:1.06~1.45)、母亲孕前超重和肥胖、高危妊娠(OR=1.95,95%CI:1.66~2.29)等是早产的危险因素。结论舟山市2002-2015年新生儿出生体重呈下降趋势,低出生体重儿和早产儿发生率呈上升趋势。新生儿性别、出生季节,母亲年龄、孕前体质指数(body mass index,BMI)...
