Among these methods, the Implant has gained popularity in sub-Saharan Africa, whereas the utilization of Intrauterine Devices (IUDs) has remained comparatively low, particularly in Burkina Faso. This study aims to evaluate the shifts in IUD and Implant usage from 2010 to 2020 and to pinpoint the factors influencing the choice of IUDs among LARCs users in Burkina Faso. Data and Methods: We conducted an analysis using data from Burkina Faso, drawn from the 2010 Demographic and Health Survey (DHS) and the 2020 PMA Phase 1 data. The 2010 DHS garnered responses from 17,087 women aged 15 - 49, achieving a response rate of 98.4%. The 2020 PMA data collected responses from 6590 women aged 15 - 49, with a response rate of 95.8%. The final sample of Long-Acting Reversible Contraceptives (LARCs) users consisted of 1502 women, including 576 women from the 2010 survey and 926 women from the 2020 survey. Results: The study demonstrates an expansion of IUD usage to include socioeconomically disadvantaged segments among LARC users. However, higher levels of education, older age, and decisions influenced by healthcare providers are correlated with the preference for IUDs over Implants. The choice of IUDs is also connected to a comprehensive understanding of contraceptive methods, suggesting potential biases in the counseling process. Conclusion: Facilitating the broader adoption of IUDs among disadvantaged groups could be achieved by improving the accessibility of IUD products and services in rural areas. Nevertheless, there should be focused initiatives to enhance access to removal services, as this factor could dissuade specific users. Further efforts are required to train healthcare providers, aiming to mitigate biases in delivering Long-Acting Reversible Contraceptives (LARCs). Providers should provide impartial counseling, irrespective of the selected type of LARC.展开更多
