Este fen\u00f3meno contribui para mortalidade materna e neonatal e pode ter diversas consequ\u00eancias econ\u00f3micas e psicol\u00f3gicas. O conhecimento dos seus determinantes pode ajudar os decisores pol\u00edticos no desenho de pol\u00edticas locais de sa\u00fade sexual e reprodutiva. O presente estudo teve como objetivo analisar os fatores determinantes da gravidez na adolesc\u00eancia no munic\u00edpio de Malanje, em Angola.M\u00e9todos: Um estudo de caso-controlo realizado entre agosto e outubro de 2022. Uma amostra de 411 mulheres adolescentes (137 gestantes e 274 n\u00e3o gestantes) foi comparada quanto a fatores sociodemogr\u00e1ficos, comportamentais, familiares e extrafamiliares. Foram aplicadas estat\u00edstica descritiva e an\u00e1lises por regress\u00e3o log\u00edstica bin\u00e1ria univariada e multivariada, com signific\u00e2ncia estat\u00edstica quando p \u2264 0,05.Resultados: A an\u00e1lise multivariada demostrou que para as mulheres de 15 - 17 anos de idade, um risco mais elevado de gravidez na adolesc\u00eancia estava associada a estados civis de uni\u00e3o de facto ou casada (ORA = 10,37; 95% IC = 1,05 - 102,83), ter 0 - 4 (ORA = 7,40; 95% IC = 1,25 - 43,77) ou 5 - 8 anos de escolaridade (ORA = 5,21; 95% IC = 1,25 - 21,77), enquanto um risco mais baixo estava relacionado com hist\u00f3ria familiar de gravidez na adolesc\u00eancia (ORA = 0,30; 95% IC = 0,11 - 0,80). Para as mulheres entre 18 - 19 anos de idade, um risco mais elevado de gravidez estava associado a in\u00edcio precoce da atividade sexual (ORA = 3,75; 95% IC = 1,05 - 13,43), m\u00faltiplos parceiros sexuais (ORA = 3,02; 95% IC = 1,23 - 7,44), enquanto um risco mais baixo estava associado a press\u00e3o dos pares (ORA = 0,35; 95% IC = 0,15 - 0,82). Em ambos os grupos, a probabilidade de engravidar foi significativamente aumentada para uso irregular ou n\u00e3o uso de contracetivos.Conclus\u00e3o: Em Malanje, a gravidez na adolesc\u00eancia \u00e9 um fen\u00f3meno multifatorial e as estrat\u00e9gias preventivas devem ter em conta idade das adolescentes. Nas adolescentes com idades entre os 15 e 17 anos \u00e9 importante reduzir o casamento precoce, atrav\u00e9s da promo\u00e7\u00e3o da educa\u00e7\u00e3o e da cria\u00e7\u00e3o de leis espec\u00edficas. Nas adolescentes mais velhas, as estrat\u00e9gias preventivas devem estar focadas nos comportamentos de risco, como o in\u00edcio precoce da atividade sexual e m\u00faltiplos parceiros. Deve ser promovida a educa\u00e7\u00e3o sexual incluindo conhecimentos sobre m\u00e9todos contracetivos.<\/jats:p>","DOI":"10.20344\/amp.22407","type":"journal-article","created":{"date-parts":[[2025,2,3]],"date-time":"2025-02-03T11:50:12Z","timestamp":1738583412000},"page":"88-98","source":"Crossref","is-referenced-by-count":0,"title":["Determinantes da Gravidez na Adolesc\u00eancia no Munic\u00edpio de Malanje, em Angola: Um Estudo Caso-Controlo"],"prefix":"10.20344","volume":"38","author":[{"given":"Kalonesse","family":"Arag\u00e3o","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Euclides","family":"Sacomboio","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cristina","family":"Teixeira","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joaquim","family":"Van-D\u00fanem","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paulo","family":"Campos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"8464","published-online":{"date-parts":[[2025,2,3]]},"reference":[{"key":"7981","unstructured":"World Health Organization.
