OBJECTIVE: We compared 12-month continuation rates, menstrual bleeding patterns and other aspects of acceptability between users of Cyclofem and users of Depo-Provera.
METHODS: The life-table method was used to calculate quarterly continuation rates. In all, 360 Kenyan women were randomly assigned to one of the two contraceptives. User-satisfaction questionnaires were administered at 6 and 12 months or at discontinuation, whichever occurred first.
RESULTS: The 1-year continuation rate was 75.4% for Depo-Provera users versus 56.5% for Cyclofem users (p<.001). Main reasons for discontinuation included difficulty making clinic visits (45.1% for Cyclofem vs. 40% for Depo-Provera), menstrual changes (14.1% vs. 12.5%) and nonmenstrual problems (15.5% vs. 12.5%). None of the Depo-Provera users and 8.5% of the Cyclofem users claimed frequency of visits as the main reason for discontinuation. In all, 70.6% of the Depo-Provera users were amenorrheic after 12 months, as were 20.8% of the Cyclofem users.
CONCLUSIONS: The 1-year continuation rate was higher for Depo-Provera than for Cyclofem. There was no important difference in discontinuation rates because of menstrual problems; the difference mainly reflected the frequency of visits required.
