北京市活产儿中巨大儿的发生及影响因素分析

目的：描述2013年北京市活产儿中巨大儿的发生情况，并对部分影响因素进行了分析和探讨。方法在2013年出生的206498名新生儿中找出出生体重≥4000 g的活产儿信息，并就性别、孕周、户籍、出生地点等因素进步比较分析。结果2013年北京市活产新生儿中巨大儿发生率为8．19％；其中，男性发生率为10．11％，女性发生率为6．10％，男、女新生儿的巨大儿发生率比较差异有统计学意义（χ2＝1104．228，P＜0．001）。新生儿性别（OR＝0．538）、分娩孕周（OR＝1．637）、出生地点（OR＝1．111）及出生季节（OR＝0．971）可能是巨大儿发生的影响因素（均P＜0．05）。结论2013年北京市巨大儿发生高于全国平均水平，有必要采用行之有效的措施控制巨大儿的发生。

Incidence of fetal macrosomia and its influencing factors in Beijing

Objective To describe the incidence of macrosomia in live births in Beijing in 2013 and to analyze and discuss some influencing factors .Methods Data of all macrosomia were collected from 206 498 newborns who were born in 2013 with birth weight greater or equal to 4 000g.Further study was implemented on the possible influencing factors of macrosomia , such as gender, gestational age, residence, birth place and other factors.Results In 2013, the incidence of macrosomia was 8.19%in Beijing.And the incidence was 10. 11% in male and 6.10%in female, respectively.The incidence of macrosomia between female and male was not significantly different (χ2=1 104.228, P<0.001).Gender, gestational age, birth place and season of birth may be the influencing factors of macrosomia (OR value was 0.538, 1.637, 1.111 and 0.971, respectively, all P<0.05).Conclusion In 2013, the incidence of fetal macrosomia in Beijing is higher than the national average value .It is necessary to adopt effective measures to control the occurrence of macrosomia .
