Analysis of unmarried adolescents and modern contraceptives initiation in Nigeria: Evidence from 2018 NDHS. Social Sciences, 11(7), 282. https://doi.org/10.3390/socsci110702822076-0760https://doi.org/10.3390/socsci11070282http://hdl.handle.net/10566/7774Nigeria 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.enUnmarried adolescentsContraceptiveNigeriaDemographic and Health Survey (NDHS)Population studiesArticle
