A case-control study of 82 urban Dominican women with a malnourished child and 82 women with a well-nourished child of the same age, sex, and neighborhood of residence revealed that the women of the control group had significantly lower parity and also had fewer living children. More women in the case group had used contraception at one time. Nevertheless, the prevalence of current contraceptive use was identical in the two groups. More women in the control group had undergone one or more spontaneous or induced abortions. Although the women in both groups were selected from the same neighborhoods, there is evidence to suggest that the the women in the control group may have had higher family incomes. The higher incomes could well account, at least in part, for the difference in parity between the two groups as well as for the difference in nutritional status in the preschool children of the mothers of these groups.
一项病例对照研究对82名居住在城市的多米尼加妇女进行了调查，这些妇女的孩子营养不良，同时选取了82名孩子营养良好的妇女作为对照，这些对照妇女与病例组妇女年龄、性别相同，且居住在同一社区。结果显示，对照组妇女的生育胎次显著更低，存活子女数量也更少。病例组中曾使用过避孕措施的妇女更多。然而，两组当前的避孕措施使用率相同。对照组中经历过一次或多次自然流产或人工流产的妇女更多。尽管两组妇女均选自同一社区，但有证据表明，对照组妇女的家庭收入可能更高。较高的收入至少可以部分解释两组在生育胎次上的差异，以及两组母亲学前儿童营养状况的差异。
