Abstract
Objective: to discuss epidemiological and demographic factors related to teenage pregnancy. Methods: this integrative literature review was based on a bibliographic search about teenage pregnancy. The stages of construction of this review were: selecting the theme, searching for articles published between 2011 and 2021 in digital databases, establishing criteria for inclusion/exclusion and discussion of articles, being selected at the end 16 articles. Results: The population fertility rate has been falling. Adolescents between 15 and 19 years old are 23% of the national fertility because of the socioeconomic vulnerability level at which these women are exposed. Regarding the risks, it is observed that the probability of deaths childbirth/pregnancy in this age group are twice higher as 20+ aged women. Furthermore, the main consequences of teenage pregnancy are dropping out of school, depression, emotional disturbances and suicidal ideation. Final considerations: The prevalence and increase in the proportion of teenage pregnancy over the years is worrying, being considered a case of public calamity in Brazil, thus needing interventions with regard, mainly, to health promotion.
