Early or teenage pregnancy is a worldwide phenomenon, considered both a social problem and a public health issue. This study analyzes the risk factors and consequences for the social development of young mothers based on a bibliographical review of research studies. A bibliographical search was conducted for studies published in Scopus and Dialnet between 2015 and 2022 that deal with the social aspects of teenage pregnancy rather than exclusively health-related issues. Two hundred twenty-seven articles were identified, and after a second review, 113 articles were selected. While rates of teenage pregnancy display divergences between geographic regions, the studies reveal common risk factors and consequences. Reproductive health programs should consider the problem from an intersectional perspective and, rather than relying exclusively on health-related policies, preventing early pregnancy requires comprehensive policies that incorporate cultural factors and seek out the underlying structural causes of inequality and poverty. This research is based on the results of the study Analysis of Teenage Pregnancy from a Human Rights and Gender-based Perspective in El Salvador and Spain, undertaken by the Medicus Mundi in collaboration with the El Salvador Intersectoral Alliance for Teenagers and Young Adults and the Ministry of Health of El Salvador.
