The prevalence rates of some of the common birth defects have been ascertained in a Black population in South Africa. The births of 29,633 infants were studied retrospectively from hospital records. The commonest defect was found to be polydactyly (10,4/1,000 births), and the other defects investigated were talipes equinovarus (1,55/1000 births), hydrocephalus (1,3/1,000 births), spina bifida and anencephaly (0,78 and 0,40/1,000 births respectively) and facial clefts (0,30/1,000 births). These rates were compared with those found in other population groups in South Africa and, in some cases, in other African countries and in Negro groups in the USA and Canada.
在南非的一个黑人种群中已确定了一些常见出生缺陷的患病率。通过回顾医院记录对29633名婴儿的出生情况进行了研究。发现最常见的缺陷是多指（每1000例出生中有10.4例），所调查的其他缺陷包括马蹄内翻足（每1000例出生中有1.55例）、脑积水（每1000例出生中有1.3例）、脊柱裂和无脑儿（分别为每1000例出生中有0.78例和0.40例）以及面部裂（每1000例出生中有0.30例）。将这些比率与在南非其他种群、某些情况下与其他非洲国家以及美国和加拿大的黑人种群中发现的比率进行了比较。
