The analysis of the data from this study, though not complete, has shown the following: 1) High rates of plural births may be expected in Ghanaian populations (3.21% for twins, 0.05% for triplets). 2) Hellin's law relating to the incidence of multiple births has been found to apply to a Ghanaian population. 3) Our data show that maternal age and parity have considerable effect on twinning. 4) Multiple pregnancies may not, in themselves, constitute a risk to the mother. On the other hand, the birthweight of the babies may be the cause of hazard at childbirth.
本研究的数据虽未完整分析，但已显示如下结果：1）加纳人群中多胎出生率可能较高（双胞胎为3.21%，三胞胎为0.05%）。2）已发现与多胎发生率相关的赫林定律适用于加纳人群。3）我们的数据表明，母亲年龄和产次对双胞胎的发生有相当大的影响。4）多胎妊娠本身可能不会对母亲构成风险。另一方面，婴儿的出生体重可能是分娩时危险的原因。
