Area of Science:
- Reproductive Health
- Family Planning
- Maternal and Child Health
Background:
- The Lactational Amenorrhea Method (LAM) is a natural family planning method based on exclusive breastfeeding.
- Previous research indicated a need to assess LAM's acceptability, satisfaction, and utilization across varied populations.
Purpose of the Study:
- To evaluate the acceptability, satisfaction, and utilization of the Lactational Amenorrhea Method (LAM) in diverse populations.
- To confirm the efficacy of LAM, with efficacy data presented in a companion paper.
Main Methods:
- A multicenter prospective study involving 11 sites across 10 different populations.
- Data collection on LAM users, with on-site entry and cleaning, followed by centralized cleaning and analysis at the Institute for Reproductive Health (IRH).
Main Results:
- Overall user satisfaction with LAM was high at 83.6%.
- Continuation with another family planning method at 9 months postpartum was 67.6%, often exceeding prior contraceptive use.
- High knowledge and understanding of LAM at discontinuation were observed, ranging from 78.4% to 88.6%.
Conclusions:
- LAM is highly satisfactory and successful across various cultures, socioeconomic statuses, and country settings (industrial and developing).
- The findings confirm LAM's acceptability and readiness for widespread integration into maternal and child health and family planning services.
