Objectives To verify the prevalence of current posttraumatic stress disorder (PTSD) in young adults, the occurrence of comorbidities and its association with quality of life. Methods This is a cross-sectional population-based study. The targeted population consisted on individuals aged 18 to 24 years old, who lived in the urban area of Pelotas-RS, Brazil. Cluster sampling was applied. PTSD and its comorbidities were assessed using the Mini International Neuropsychiatric Interview (MINI 5.0), whereas quality of life was evaluated with the eight domains of the Medical Outcomes Survey Short-form General Health Survey (SF-36). Results A total of 1,762 young adults were selected. The prevalence of PTSD was 2.1% and current episode of depression was the most prevalent comorbidity (71.9%). The individuals with PTSD had lower scores in all domains of quality of life. Conclusion These findings indicate that PTSD is associated with other psychopathologies, especially depression, and it has a substantial impact over quality of life in a sample of young adults.

OBJECTIVE: To estimate the prevalence of depression and correlate clinical and demographic characteristics in pregnant women assisted by the public health system in the city of Pelotas, RS, Brazil. METHOD: We performed a cross-sectional study focused on pregnant women assisted by the public health service. The Edinburgh Postnatal Depression Scale (EPDS) was used to screen for depression. RESULTS: In a sample of 1,264 pregnant women aged 12-46 years, 21.1% (n = 255) presented a depressive episode during pregnancy. The presence of depression was associated with older age, lower education, lack of a cohabiting partner, not being primiparous, planned pregnancy, abortion thoughts, psychological or psychiatric treatment, smoking and alcohol consumption during pregnancy, and stressful events. CONCLUSION: Pregnant women assisted by the Brazilian public health system presented a high prevalence of depression. Psychiatric history, lack of support, and stressful events increase the probability of antenatal depression.OBJETIVO: Estimar a prevalência de depressão, bem como fatores clínicos e características demográficas associados em grávidas assistidas por meio do sistema público de saúde da cidade de Pelotas, RS, Brasil. MÉTODO: Foi realizado um estudo transversal tendo como população-alvo as grávidas assistidas pelo sistema público de saúde. Para o rastreio da depressão foi utilizada a Edinburgh Postnatal Depression Scale. RESULTADOS: Em uma amostra de 1.264 mulheres grávidas com idade de 12 a 46 anos, 21,1% (n = 255) apresentaram episodio depressivo durante a gravidez. A presença de depressão foi associada com ter mais idade, menor grau educacional, não morar com companheiro, não ser primigesta, ter planejado a gestação, idealizar o aborto, ter feito tratamento psicológico ou psiquiátrico, consumir tabaco e/ou álcool durante a gravidez e ter sofrido algum evento estressor. CONCLUSÃO: As mulheres grávidas acompanhadas pelo sistema público de saúde apresentaram alta prevalência de depressão. História psiquiátrica, baixo suporte e eventos estressores aumentam a probabilidade de depressão no período pré-parto.
