Contraceptive continuation and its determinants in Benin

To understand better the rates of continuation of different contraceptive methods, a study in 12 family planning centers in Cotonou and Porto Novo, the two largest cities in Benin, was conducted. From January 1 to December 31, 1993, 944 questionnaires completed by new women acceptors of one of three methods of contraception (oral contraceptive, injection, or IUD) were analyzed. For all methods of contraception, the average length of follow-up was 9.5 months. From the start of the analysis, 44.4% (n = 419) of the women were regularly followed, 49.5% (n = 467) were not regularly followed, and 6.1% (n = 58) reported discontinuation of the method. One year after beginning the use of contraception, the cumulative proportion of women at risk of becoming pregnant, for all the methods together, was 42.0% (38.6-45.4%). Age was associated with the probability of abandoning oral contraception (p = 0.01). Three months after the start, the cumulative proportion of drop-out women having chosen oral contraceptive was 37.2% (22.8-51.6%) of the less than 20-year-olds, 19.0% (14.3-23.7%) of the 20- to 30-year-olds, and 23.4% (15.6-31.2%) of the over 30-year-olds. In contrast, drop-out was not associated with age for women using injection (p = 0.96) or the IUD (p = 0.47). Our results indicate a relatively high and rapid rate of discontinuation for modern contraceptive methods, particularly for young women having chosen oral contraceptive. This finding should incite the family planning educators to give more emphasis to the counseling programs, especially during the first three months.
