THOMAZINI, Isabela Fleury Skaf et al. Risk factors related to premature labor in pregnant adolescents: an integrative literature review. []. , 15, 44, pp.416-427. ISSN 1695-6141.

Introduction: Premature labor is one of the main complications in pregnancy and an important cause of neonatal morbidity and mortality. It is difficult to diagnose and there may be a variety of causes. The literature indicates that teenage pregnancy is a risk factor and may be considered on its own or in combination with others. Objective: Study the evidence in the literature on the subject: premature labor, relationship with teenage pregnancy and risk factors. Material and method: Integrative literature review based on the databases LILACS; MEDLINE, SciELO and PubMed. The search was performed in August 2015 with the following inclusion criteria: articles published in Portuguese, English and Spanish, from 2009 to 2014, which meet the review objective. Only studies with primary data were used and review studies were excluded. The search yielded 511 articles, of which the following were excluded: 339 studies because they were published outside the stipulated time period; 155 because they did not comply with the objectives; and 6 after they were fully read. The final sample consisted of 11 articles. Results: Analysis of the selected publications resulted in the identification of four thematic categories: access to and frequency of prenatal care; birth control and family planning education for adolescents; social, demographic and economic aspects vs. biological immaturity and social network support. Conclusion: The present study found that there is a relationship between teenage pregnancy and premature labor, although multiple risk factors are involved. Therefore, it is suggested that more studies be carried out on this topic.
