The birth weight of 996 singleton infants was recorded soon after delivery and analysed. The mean birth weight was higher in males 3203 +/- 350g. than in females 3186 +/- 338g. The difference in mean birth weight between male and female infants was not significant (P greater than 0.5). There was no definite relationship between parity and the mean birth weight of both male and female infants but there was a significant difference between the mean weight of the various parity groups for both male and female infants. The birth weight rose with increasing maternal age for both sexes of infants. The differences in mean birth weight in the various maternal age groups however, were not significant. The incidence of low birth weight in this series was 12.2%; being lower in males which comprised 46.2% of the total as compared to 53.8% for the female infants. Our results were compared with those in studies from other parts of Nigeria as well as from other countries.
996名单胎婴儿出生后不久记录其出生体重并进行分析。男婴平均出生体重为3203±350克，高于女婴的3186±338克。男、女婴儿平均出生体重的差异不显著（P＞0.5）。胎次与男、女婴儿的平均出生体重之间没有明确关系，但不同胎次组的男、女婴儿平均体重之间存在显著差异。婴儿出生体重随母亲年龄增加而上升。然而，不同母亲年龄组的平均出生体重差异不显著。本系列中低出生体重的发生率为12.2%；男婴发生率较低，占总数的46.2%，而女婴为53.8%。我们将结果与尼日利亚其他地区以及其他国家的研究结果进行了比较。
