This paper describes a new indirect technique for deriving population-based estimates of maternal mortality. The technique, called the "sisterhood method," is relevant to developing countries where the alternative data sources and approaches to estimation are often inadequate and inappropriate. The sisterhood method uses the proportions of adult sisters dying during pregnancy, childbirth, or the puerperium reported by adults during a census or survey, to derive a variety of indicators of maternal mortality. The first field trial of the method was carried out in the North Bank Division of The Gambia, West Africa, in 1987. The results indicate a lifetime risk of maternal mortality of 0.0584, or 1 in 17, approximating a maternal mortality ratio of 1,005 per 100,000 live births, which is consistent with previous estimates for this region.
本文介绍了一种新的间接方法，用于得出基于人群的孕产妇死亡率估计值。该方法称为“姐妹法”，适用于发展中国家，在这些国家，用于估计的替代数据来源和方法往往不足且不适用。姐妹法利用人口普查或调查中成年人报告的成年姐妹在孕期、分娩期或产褥期死亡的比例，得出各种孕产妇死亡率指标。该方法的首次现场试验于1987年在西非冈比亚的北岸分区进行。结果表明，孕产妇终身死亡风险为0.0584，即17分之一，近似于每10万例活产中有1005例孕产妇死亡的死亡率，这与该地区先前的估计一致。
