Abstract
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.
