From 1983 to 1988, natural family planning programs were conducted in Liberia and Zambia. In Liberia 1055 and in Zambia 2709 women used natural family planning to avoid pregnancy. These users could become pregnant, discontinue use of the method, or become autonomous users. Women who changed intention did not stop use of natural family planning and were not treated as discontinuations. In a multivariate analysis, client's age, breastfeeding status, employment, urban/rural residence, time of registration in the program, and visit intensity were significantly associated with the outcomes. The most consistent association was that women who entered the programs in the later time periods were more likely to become autonomous users and less likely to discontinue use of the method or to experience an accidental pregnancy.
1983年至1988年期间，利比里亚和赞比亚开展了自然计划生育项目。在利比里亚，有1055名妇女，在赞比亚有2709名妇女采用自然计划生育来避免怀孕。这些使用者可能会怀孕、停止使用该方法或成为自主使用者。改变意愿的妇女并未停止使用自然计划生育，也未被视为中止使用。在多变量分析中，服务对象的年龄、母乳喂养状况、就业情况、城乡居住情况、项目登记时间以及就诊频率与结果显著相关。最一致的关联是，在较晚时间段进入项目的妇女更有可能成为自主使用者，且较少可能停止使用该方法或意外怀孕。
