Long acting reversible contraceptive utilization and its associated factors among modern contraceptive users in high fertility sub-Saharan Africa countries: a multi-level analysis of recent demographic and health surveys

Background Long-acting reversible contraceptives (LARC) have been hailed as one of the safest and most effective methods of contraception. However, the use of LARC is low in the world, including Sub Saharan Africa; therefore, the aim of this study was to assess LARC utilization and associated factors among modern contraceptive users in high fertility SSA countries. Methods Data for this study was obtained from the most recent Demographic and Health Surveys. A total weighted sample of 14,828 reproductive age women was included. A multilevel mixed-effect binary logistic regression model was fitted to identify the significant associated factors of long acting reversible contraception utilization. Finally, the Adjusted Odds Ratio (AOR) with 95% confidence interval was used to declare as statistical significance. Results Overall prevalence of LARC utilization was observed to be 20.1% (19.45, 20.74). The factors significantly associated with the utilization were women’s age ≥ 35 years (AOR = 1.42; 95% CI: 1.19,1.68), having media exposure (AOR = 1.13; 95% CI: 1.05, 1.28), number of alive children: 1–2 (AOR = 2.35; 95% CI: 1.38, 4.01), 3–4 (AOR = 2.98; 95% CI: 1.74, 5.10), $$\ge$$ 5 (AOR = 2.82; 95% CI:1.63, 4.86), have no history of abortion (AOR = 1.33; 95% CI: 1.17,1.51) and who have no big problem with distance to the health facility (AOR = 1.29; 95% CI: 1.16, 1.43). Conclusion The use of long acting reversible contraception in this study was relatively low. To improve the utilization of long acting reversible contraceptives governments, policymakers, and stakeholders should implement health promotion strategies through media and improve accessibilities of health facilities.
