Background Despite efforts to improve its uptake, contraceptive use in Nigeria remains low. Understanding regional
disparities and sociodemographic determinants of contraceptive intention is crucial for developing effective family
planning strategies. This study aimed to investigate these factors in women of reproductive age in Nigeria.
Methods This cross-sectional study analysed data from 36,179 women aged 15–49 participating in the 2018 Nigerian
Demographic and Health Survey (NDHS). Bivariate and multivariable logistic regression analyses were conducted to
assess the association between sociodemographic factors and contraceptive use intention.
Results The overall prevalence of contraceptive intentions was 39.18%, with significant regional variation. South East
had the highest intention at 44.85%, while North East had the lowest intention at 34.76%. Education was a strong
predictor, with those with higher education showing 2.657 times greater odds of using contraception (AOR: 2.657,
95% CI: 2.339–3.019, p<0.001). Muslim women and rural residents exhibited lower odds of intention, while women
aged 20–24 years had the highest odds (AOR: 1.305, 95% CI: 1.187–1.435, p<0.001).
Conclusion There were significant regional disparities and complex sociodemographic patterns in contraceptive
intention among Nigerian women. Tailored interventions addressing educational, religious, economic, and
geographical barriers are required to increase contraceptive uptake and improve reproductive health outcomes
