Abstract: Nigeria is one of Africa’s most populous countries. Nigeria’s population is expected to exceed 400 million by 2050, putting it among the top five most populous countries in the world. High birth rates, limited contraception use, and early marriage are the main causes of this rapid increase. In Nigeria, adolescents play a substantial role in these issues, with 117 births per 1000 girls aged 15–19 years. Data for this article comes from the 2018 Nigerian Demographic and Health Survey (NDHS). Our sample consisted of 1014 sexually active unmarried adolescents aged 15–19 years. Kaplan Meier’s curve, Log Rank Test, and Cox proportional hazards model were modeled to estimate the parameters at p > 0.05. Findings show that the average time to the first use of modern contraceptives after sexual initiation is two years. Initiating sex at age 15 or later, belonging to the richest household wealth quintile, and use of the internet is associated with the early initiation of modern contraceptive methods, while residing in the northwest region and being older are associated with a low incidence of modern contraceptive use. Results indicate a deferred initiation of modern contraceptives after first sexual encounter. It has become imperative for tailored interventions to improve the time of initiation of contraceptives, so as to reduce the associated burdens and consequences.
