The study employed the ecological systems theory as its framework to investigate the influence of religion, education, wealth index, and geographical area on teenage pregnancy. The ICF provided the secondary data from the 2018 Nigeria Demographic Health Survey. The study utilised data collected from a sample of women aged 15-49 residing in 40,427 households. The data were examined using percentages, a Binary Logistic Regression model, and the Pearson Chi-Square Statistic. The study findings indicate that both educational attainment and wealth index exert a substantial influence on the occurrence of adolescent pregnancy in Nigeria. The study also demonstrated that geopolitical zones have minimal impact on teenage pregnancy. Nevertheless, religion has no discernible influence on teenage pregnancy. The study demonstrates the influence of education and economic empowerment on decreasing rates of adolescent pregnancy. It emphasises the significance of developing intervention programmes tailored to individual regions, taking into account cultural subtleties. The study proposed the adoption of a multifaceted approach, encompassing comprehensive sex education, economic empowerment programmes, culturally sensitive interventions, and community-based efforts that engage healthcare practitioners and religious leaders. This study provides valuable insights into the complex nature of adolescent pregnancy and offers ways to address reproductive health issues among teenagers in Nigeria. As a result, it contributes to policy making, education, and the growth of healthcare in the country.
