The objective of this work is to analyze the correlation between signs, symptoms and complications and the presence of stress in pregnant adolescents in health facilities in Maceio, Alagoas, Brazil. Quantitative, cross-sectional data were collected through questionnaire survey and tests of applied stress in adolescents treated in prenatal care. Data were analyzed by Epi Info version 3.5, using the odds as a statistical measure. The survey involved 140 pregnant girls, aged from 10 to 19 years. Results show that 80.7% of them had some degree of stress, 57.1% being in the resistance phase and 18.6% at the stage of exhaustion. Statistical association was found between stress and some symptoms. The results indicate the presence of stress in adolescence and the need for special attention to the mental health of these women.
