Abstract

A Natural Family Planning service was evaluated at the end of a 30-month developmental phase. There were 444 women taught and 322 method acceptor of which 248 intended to avoid pregnancy. NFP clients were older (mean age 26.9 vs 22.4 and 23.7 for comparison groups), and a larger percentage were married (83.1 per cent vs 23.0 per cent for the comparison group). After one year of use, the unplanned pregnancy rate was 14.4 per cent and the total dropout rate was 37.6 per cent by life table analysis.
