This population-based study focused on the validity of the Patient Health Questionnaire-9 (PHQ-9) for screening major depressive episodes in the general population in Pelotas, Rio Grande do Sul State, Brazil. Households were selected by multi-stage sampling, and adults (> 20 years) were invited to participate. The gold standard was the structured diagnostic Mini International Neuropsychiatric Interview (MINI), applied by psychiatrists and psychologists. Both the PHQ-9 and the MINI were applied in the subjects' homes. In a total of 447 participants (191 men and 256 women), the continuous analysis identified > 9 as the cutoff point with the highest sensitivity (77.5%; 61.5-89.2) and specificity (86.7%; 83.0- 89.9). Use of the test's algorithm decreased the sensitivity to 42.5% (27.0-59.1), while the specificity increased to 95.3% (92.8-97.2). The PHQ-9 proved appropriate for screening major depressive episodes. For greater sensitivity, the continuously scored PHQ-9 proved more adequate than the algorithm for screening major depressive episodes in the community.

ObjectivesThe study aims to evaluate the magnitude of multimorbidity in Brazilian adults, as well to measure their association with individual and contextual factors stratified by Brazilian states and regions.MethodsA national-based cross-sectional study was carried out in 2013 with Brazilian adults. Multimorbidity was evaluated by a list of 22 physical and mental morbidities (based on self-reported medical diagnosis and Patient Health Questionnaire-9 for depression). The outcome was analysed taking ≥2 and ≥3 diseases as cut-off points. Factor analysis (FA) was used to identify disease patterns and multilevel models were used to test association with individual and contextual variables.ResultsThe sample comprised 60 202 individuals. Multimorbidity frequency was 22.2% (95% CI 21.5 to 22.9) for ≥2 morbidities and 10.2% (95% CI 9.7 to 10.7) for ≥3 morbidities. In the multilevel adjusted models, females, older people, those living with a partner and having less schooling presented more multiple diseases. No linear association was found according to wealth index but greater outcome frequency was found in individuals with midrange wealth index. Living in states with higher levels of education and wealthier states was associated with greater multimorbidity. Two patterns of morbidities (cardiometabolic problems and respiratory/mental/muscle–skeletal disorders) explained 92% of total variance. The relationship of disease patterns with individual and contextual variables was similar to the overall multimorbidity, with differences among Brazilian regions.ConclusionsIn Brazil, at least 19 million adults had multimorbidity. Frequency is similar to that found in other Low and and Middle Income Countries. Contextual and individual social inequalities were observed.

ABSTRACT:Objective: To identify the prevalence of depressive symptoms and associated factors in elderly. Methods: Cross-sectional study of population-based sample of 1,593 individuals aged 60 years or more in the urban area of Bagé, Rio Grande do Sul, Brazil, in 2008. Data were collected in household interviews. The prevalence of depressive symptoms was assessed using the Geriatric Depression Scale. The analysis was performed using Poisson regression with robust variance estimation. Results: The prevalence of depressive symptoms was 18.0%, with the 95% confidence interval 16.1 -19.9. The majority of the sample consisted of women (62.8%). The mean age was 70 years, with a 8.24 standard deviation (SD); 25.1% of seniors aged 60 to 64 years and 31.2% were 75 years or older. In the adjusted analysis, depressive symptoms were significantly associated (p value < 0.05) with the elderly female, yellow, brown or indigenous descendancy, lower economic status, retired, with history of heart problems, incapacity to basic and instrumental activities of daily living, worse self-rated health and dissatisfaction with life in general. Age, marital status, education, self-reported hypertension and diabetes were not associated with depressive symptoms after adjusting for confounders. Conclusion: The high prevalence of depressive symptoms in the population requires investment in preventive actions, noting the need for practices that promote active aging with the maintenance of functional activity, improving self-rated health and life satisfaction.

BackgroundStandardized questionnaires designed for the identification of depression are useful for monitoring individual as well as population mental health. The Edinburgh Postnatal Depression Scale (EPDS) has originally been developed to assist primary care health professionals to detect postnatal depression, but several authors recommend its use outside of the postpartum period. In Brazil, the use of the EPDS for screening depression outside the postpartum period and among non-selected populations has not been validated. The present study aimed to assess the validity of the EPDS as a screening instrument for major depressive episode (MDE) among adults from the general population.MethodsThis is a validation study that used a population-based sampling technique to select the participants. The study was conducted in the city of Pelotas, Brazil. Households were randomly selected by two stage conglomerates with probability proportional to size. EPDS was administered to 447 adults (≥20 years). Approximately 17 days later, participants were reinterviewed by psychiatrics and psychologists using a structured diagnostic interview (Mini International Neuropsychiatric Interview, MINI). We calculated the sensitivity and specificity of each cutoff point of EPDS, and values were plotted as a receiver operator characteristic curve.ResultsThe best cutoff point for screening depression was ≥8, with 80.0% (64.4 - 90.9%) sensitivity and 87.0% (83.3 - 90.1%) specificity. Among women the best cutoff point was ≥8 too with values of sensitivity and specificity of 84.4% (67.2 – 94.7%) and 81.3% (75.5 – 86.1%), respectively. Among men, the best cutoff point was ≥7 (75% sensitivity and 89% specificity).ConclusionsThe EPDS was shown to be suitable for screening MDE among adults in the community.

Multimorbidity was common in the studied population. The observed patterns may be used to generate and improve Brazilian diseases guidelines.
