The prevalence of low birthweight in many African countries is higher than in developed countries. This is largely because of the greater number of babies who are light for gestational age. In general, mean birthweights of African babies at various gestational ages are lower than those of developed countries. This is due mainly to environmental factors, but an increased prevalence of twinning is one genetic factor. When babies of mothers in optimum health were studied, birthweights for gestational age were similar to Caucasian babies.
许多非洲国家低体重儿的患病率高于发达国家。这主要是因为孕周小于胎龄的婴儿数量更多。一般来说，非洲婴儿在不同孕周的平均出生体重低于发达国家。这主要是环境因素导致的，但双胞胎出生率上升是一个遗传因素。当对健康状况最佳的母亲所生的婴儿进行研究时，其孕周别出生体重与白人婴儿相似。
