The lactational amenorrhoea method (LAM) is an effective contraceptive option in developing countries. Post-partum, of the women who accept to apply LAM, many never do. Our aim was to determine the actual use of LAM.
A group of 326 post-partum women who accepted LAM use were recruited. After 6 months, they were asked if they actually had applied the method or not. In a logistic regression analysis, nine socio-demographic and clinical variables were studied as predictors of actual LAM use. An alpha level was set at 0.05.
Overall, of the 326 women, only 61 (18.7%) actually applied LAM. The mean duration of LAM use was 4.3 +/- 0.2 months. The main reason for not applying LAM was that women thought the method was ineffective (66.0%). The variable time of menses resumption emerged as a predictor of LAM use (p = 0.001).
Despite post-partum acceptance, most women did not actually apply LAM. In our setting as well as in other developing countries, regular contacts with a health care provider could improve LAM use.
哺乳期闭经法（LAM）在发展中国家是一种有效的避孕方法。产后，许多接受采用LAM的女性从未实际使用过该方法。我们的目的是确定LAM的实际使用情况。
招募了一组326名接受使用LAM的产后女性。6个月后，询问她们是否实际采用了该方法。在逻辑回归分析中，研究了9个社会人口统计学和临床变量作为LAM实际使用情况的预测因素。设定α水平为0.05。
总体而言，在这326名女性中，只有61名（18.7%）实际采用了LAM。LAM的平均使用时长为4.3±0.2个月。未采用LAM的主要原因是女性认为该方法无效（66.0%）。月经恢复时间这一变量成为LAM使用情况的预测因素（p = 0.001）。
尽管产后接受了LAM，但大多数女性并未实际采用该方法。在我们的研究环境以及其他发展中国家，与医疗服务提供者定期接触可能会提高LAM的使用率。
