The use of contraceptives among students is influenced by various socio-economic factors, including age, awareness, and income, the cost of contraceptives, partner contributions, and access to contraceptives on the student's campus. This study evaluated the impact of these factors on contraceptive use and identified the most commonly used contraceptives among students at Sokoine University in Morogoro. The study employed a cross-sectional design and was conducted from May to June 2024 among 384 undergraduate students from the Edward Moringe and Solomon Mahlangu campuses. Participants were selected through random sampling, and data was collected using a pre-tested structured questionnaire that included both open and closed-ended questions. The data were analyzed using descriptive statistics and logistic regression. The factors influencing contraceptive utilization were assessed using logistic regression analysis. A P-value of less than 0.05 was considered statistically significant. This study showed that the partner’s contribution(P<0.04), religion(P<0.05), contraceptive use with partner approval(P<0.03), and contraceptive costs (P< 0.03) are significant predictors of the utilization of modern family planning methods among students at Sokoine University of Agriculture. The common method used more by male (72%) students than females (28%) followed by hormonal pills which is more common in females (76%) than in male (24%) students. The findings of this study suggest that socio-economic factors play an important role in influencing students’ decisions about using contraceptives. Interventions that target these factors, such as providing educational programs and increasing access to modern family planning methods, could help improve contraceptive utilization among students and reduce unintended pregnancies.
