Factors associated with adolescent pregnancy and public health interventions to address in Nigeria: a scoping review

Abstract

BackgroundAdolescent pregnancy is a global public health and social problem that affects both developed and developing countries. Reducing adolescent pregnancy is central to achieving sustainable development goals. In 2021 Nigeria’s Adolescent pregnancy was 106 per 1000 and showed an increasing rate. This study, therefore, aims to explore the literature to map the risk factors and interventions against adolescent pregnancy in Nigeria.MethodA scoping review of studies published between January 2007 and December 2022 using PubMed, Web of Science and Africa Journals Online were searched using the keywords' adolescent pregnancy' AND 'Nigeria'. Studies were screened using the eligibility criteria.ResultsA total of 241 articles, of which 229 were identified through the databases and 12 were identified through hand search. After the full-text review, 28 studies met the inclusion criteria and were included in the final review. In Nigeria, the prevalence of adolescent pregnancy is between 7.5 and 49.5%. Associated factors for adolescent pregnancy in Nigeria are multifactorial, including individual, community, societal, school, family, and peer factors. Policies on adolescent sexual and reproductive health exist in Nigeria. Still, the policies need more sponsorship, implementation, and monitoring, while only some interventions on adolescent pregnancy majorly based on contraceptives and education of health providers are available in Nigeria.ConclusionAssociated factors for adolescent Pregnancy in Nigeria are multidimensional, with educational attainment and wealth index being the highest associated factor. Intervention strategies aimed at the educational level have been identified as a critical factor in curbing adolescent pregnancy. Thus, policies on sexual, reproductive, and mental health development specifically targeting adolescents to reduce the cycle of societal dependence by empowering this group economically and educationally are justifiably warranted.
