研究目标-测试可在非洲农村健康调查中易于实施的家庭财富和收入代理测量的有效性。设计数据来自四个不同的综合住户调查。本文描述了选择财富代理的基本假设，并在两种不同的设置中评估了与真实价值的相关性。开发支出代理，然后在代表同一人口的两个独立数据集中测试其可重复性。环境——马里、马拉维和科特迪瓦的农村地区（两次全国调查）。参与者：随机抽取各地区农村家庭（n=275、707、910和856）。主要结果：在马里和马拉维，财富代理与更复杂的货币价值方法高度相关（r大于等于0.74）。对于科特迪瓦的农村地区，可以生成一个仅包含10个支出项目的列表，其值与所有项目的总合高度相关（r=0.74，发展数据集，r=0.72，验证数据集）。在发展中国家，家庭总支出是可以接受的替代家庭收入的方法。结论：在非洲农村地区，估算家庭财富和支出是可行的，而不需要大幅延长主要关注健康结果的调查问卷。
Study objective-To test the validity of proxy measures of household wealth and income that can be readily implemented in health surveys in rural Africa.Design-Data are drawn from four different integrated household surveys. The assumptions underlying the choice of wealth proxy are described, and correlations with the true value are assessed in two different settings. The expenditure proxy is developed and then tested for replicability in two independent datasets representing the same population.Setting-Rural areas of Mali, Malawi, and Cote d'Ivoire (two national surveys).Participants-Random sample of rural households in each setting (n=275, 707, 910, and 856, respectively).Main results-In both Mali and Malawi, the wealth proxy correlated highly (r greater than or equal to 0.74) with the more complex monetary value method. For rural areas of Cote d'Ivoire, it was possible to generate a list of just 10 expenditure items, the values of which when summed correlated highly with expenditures on all items combined (r=0.74, development dataset, r=0.72, validation dataset). Total household expenditure is an accepted alternative to household income in developing country settings.Conclusions-It is feasible to approximate both household wealth and expenditures in rural African settings without dramatically lengthening questionnaires that have a primary focus on health outcomes.
