Abstract
Objective To estimate the sex ratios at birth(SR B) forlivebirths 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.关键词
