This study assesses the quality of Demographic and Health Survey (DHS) data regarding self-reported current use of the lactational amenorrhea method (LAM). LAM is an important modern contraceptive method that, when practiced correctly, has a 98 percent effectiveness rate six-months postpartum. The objectives of this study are to examine the accuracy of self-reported LAM use, compared with the constructed correct-practice variable, and to explore differentials in accuracy measures by characteristics at the individual and survey level by analyzing data from 73 DHSs conducted in 45 countries between 1998 and 2011. Findings reveal that only 26 percent of reported LAM users meet the criteria for correct LAM practice. We discuss the implications for future DHS data collection and for family planning and maternal and child health programming.
本研究评估了人口与健康调查（DHS）数据中关于自我报告的哺乳期闭经方法（LAM）当前使用情况的数据质量。LAM 是一种重要的现代避孕方法，正确使用时，产后六个月的有效率为 98%。本研究的目的是检验自我报告的 LAM 使用情况与构建的正确实践变量的准确性，并通过分析 1998 年至 2011 年间在 45 个国家进行的 73 项 DHS 数据，探讨个人和调查水平特征对准确性衡量的差异。研究结果表明，只有 26%的报告 LAM 用户符合正确 LAM 实践的标准。我们讨论了对未来 DHS 数据收集以及计划生育和母婴健康规划的影响。
