Factors associated with modern contraceptives use in Nigerian women: a systematic review of quantitative studies

Background Contraceptive use is essential for promoting sexual and reproductive health, directly impacting publichealth and national development through effective fertility management. In Nigeria, however, the adoption of moderncontraceptive methods remains consistently low, contributing to high maternal mortality rates despite a broad awarenessof contraceptive options among women of reproductive age. The systematic review synthesised key factors associatedwith the utilisation of modern contraceptives among Nigerian women of reproductive age, identifying specific influenceson contraceptive uptake to guide future health interventions.Method A comprehensive search was conducted across three databases, MEDLINE, Scopus, and Web of Science, toidentify studies examining the determinants of modern contraceptive use among Nigerian women. Eligible studies wereassessed and manually extracted, and findings were consolidated in a narrative review format.Results From the literature search, ten studies met the criteria for inclusion. The synthesis highlighted a generally highlevel of awareness regarding contraceptive methods among Nigerian women, although modern contraceptive preva-lence remains significantly low. The male condom emerged as the most known and utilised contraceptive method, whileimplants and injectables were mostly used by women.Key factors influencing contraceptive uptake were categorised into sociodemographic, economic, cultural, and religiousdomains. Barriers to modern contraceptive use included a strong desire for additional children, concerns about sideeffects, spousal opposition, limited access to contraceptive services, and a lack of comprehensive knowledge.Conclusion Collaborative efforts between health agencies, community leaders, and advocacy groups should priori-tise raising awareness, particularly through culturally sensitive education, to help mitigate sociocultural and economicobstacles. Additionally, it is crucial to involve male partners in these initiatives, as their support and understanding cansignificantly influence contraceptive decisions, helping to overcome some of the barriers to use. Strengthened advocacyefforts and inclusive educational programs are imperative to improving contraceptive uptake and ultimately enhancingreproductive health outcomes in Nigeria.
