Multimorbidity prevalence and patterns at the baseline of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).

Background: To identify multimorbidity patterns, by sex, according to sociodemographic and lifestyle in ELSA-Brasil.

Methods: Cross-sectional study with 14,516 participants from ELSA-Brasil (2008-2010). Fuzzy c-means was used to identify multimorbidity patterns of 2+ chronic morbidities, where the consequent morbidity had to occur in at least 5% of all cases.

Depression is a risk factor for metabolic syndrome: Results from the ELSA-Brasil cohort study.

Introduction: Metabolic Syndrome (MetS) and depression comorbidity has been recognized, but its directionality is still uncertain. The aims of this study was to assess the association between depression (diagnosis and severity) and MetS (components, diagnosis and trajectory) in the baseline and over a 4-year follow-up period.

Material And Methods: Baseline and follow-up data from 13,883 participants of the Brazilian Longitudinal Study of Adult Health were analyzed.

Comparing machine learning algorithms for multimorbidity prediction: An example from the Elsa-Brasil study.

Background: Multimorbidity is a worldwide concern related to greater disability, worse quality of life, and mortality. The early prediction is crucial for preventive strategies design and integrative medical practice. However, knowledge about how to predict multimorbidity is limited, possibly due to the complexity involved in predicting multiple chronic diseases.

Consumption of Omega-3 and Maintenance and Incidence of Depressive Episodes: The ELSA-Brasil Study.

Depression affects 264 million persons in the world, accounting for some 4.3% of the global burden of disease. Current studies indicate that the decrease in the consumption of omega-3 food sources is associated with the increasing incidence of depression.

Associations of depression and intake of antioxidants and vitamin B complex: Results of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).

Background: Optimum functioning of the central nervous system is dependent on a wide range of nutrients, so mental illness can be impacted by diet via several mechanisms. We aimed to investigate the associations of antioxidants (vitamin A, C and E, and selenium and zinc) and vitamin B complex (B6, folate and B12) intake with depression in 14,737 subjects of the Brazilian Longitudinal Study of Adult Health.

Methods: Baseline cross-sectional data was analyzed.

Dimensional structure of the demand control support questionnaire: a Brazilian context.

Unlabelled: According to Karasek, job strain results from an interaction between high demands and low decision latitude.

Purpose: To reassess the dimensional structure and evaluate the internal consistency of demand control support questionnaire (DCSQ), a shortened version of job content questionnaire that was not sufficiently evaluated in validation studies.

Methods: The study investigated 825 workers who completed the DCSQ in Rio de Janeiro, Brazil; to 399 workers, the questionnaire was self-administered at a hospital (2004-2005), and 426 workers were interviewed at nine restaurants (2006-2007).
