Abstract

Uptake and continuation of long acting reversible contraceptives (LARC) such as subdermal levonorgestrel implants are pivotal to the achievement of some sustainable development goals (SDG). We evaluated Jadelle uptake and factors affecting its discontinuation in the first three years of initiation at the Family Planning Clinic of the College of Medicine, University of Lagos (CMUL), Nigeria. A retrospective cohort study was conducted among 517 consecutive new Jadelle acceptors, at the family planning clinic of CMUL, between 1 October 2007 and 30 September 2010, who were followed up till 30 September 2011. Survival life table analysis, Kaplan-Meier plots and multivariable Cox proportional hazard regression were conducted to evaluate factors affecting time to Jadelle discontinuation. Stata version 13 statistical software (StataCorp USA) was used for analysis. The mean age of Jadelle acceptors was 32.9 (S.D: ±5.4) years and uptake rate of Jadelle was 61.8%. The overall discontinuation rate was 19 per 100 women-years while the 1-year, 2-year and 3-year Jadelle discontinuation rates were 7.1%; 27.0% and 58.1% respectively. Increased age, (P=0.047) and previous contraceptive use (P <0.001) were independent predictors of Jadelle discontinuation. Menstrual irregularity (51.4%) and intention to get pregnant (40.3%) were the commonest reasons for discontinuation. The failure rate was low at 0.27 per 100 women-years. This study showed that Jadelle had a high uptake rate complimented by a low failure rate; and is quite suitable for postpartum childbirth spacing as well as ongoing long term contraception.
