摘　　要：目的　了解住院分娩婴儿的出生性别比。方法　采用 1987～ 1992年全国出生缺陷监测网监测的住院分娩的围产儿资料 ,计算活产婴儿的出生性别比。结果　 1987～ 1992年全国多数省 (市、自治区 )住院分娩婴儿的出生性别比偏高 ,且有上升趋势。城镇妇女住院分娩婴儿的出生性别比 1987～ 1989年基本正常 ,而 1990～1991年略有上升 ;乡村妇女住院分娩婴儿的出生性别比偏高 ,且呈逐年上升趋势。年龄 2 0岁以下、文化程度低的母亲分娩的婴儿出生性别比偏高 ,第二孩及以上的婴儿的出生性别比也较高。结论　我国婴儿的出生性别比偏高 ,可能与性别偏好有关。Objective To estimate the sex ratios at birth(SR B) for livebirths in hospitals in China. Methods Data were c ollected by the birth defects monitoring network. The livebirths with gestation of 2 8 weeks or over delivered in hospitals of 30 provinces, municipalities and auton omous regions all over the country from 1987 to 1992 were analyzed and used for calculating the SRB.Results The high male bias in SRB was obser ved in the data from most areas, and there was an upward trend of SR B, especially in rural areas. Th e SRB for livebirths in the hospitals of urban areas was no rmal from 1987 to 1989, and rose to 108.9 in 1992. The SRB for rural areas was high and was 109.9 in 1987, and rose to 111.8 in 1992. The SRB for livebirths gi ven by the mothers under 20 years of age and coming from lower educational backg round was highe r than that for others. The SRB for higher parities was even higher. Co nclusion The SRB in China is high; this is possibly related to sex preference. Under reporting of female neonates and *missing females* are not the main causes of the rising SRB.
