Abstract: | Few studies have evaluated the association between diet and mental disorders, and it has been established that omega-3 (n-3) fatty acids may have a beneficial effect for sufferers of anxiety disorders. This study is part of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)-a population-based cohort study on diet and mental health-and searched for associations between anxiety disorders and consumption of n-3 polyunsaturated fatty acids (PUFA). The study had a cross-sectional design, with a total sample of 12,268 adults. Dietary exposure was measured by a quantitative food-frequency questionnaire, and mental diagnoses were assessed by the Clinical Interview Schedule-Revised Version and diagnosed according to the International Classification of Diseases (ICD-10). Logistic regression models were built using quintiles of n-3, omega 6 (n-6), n-6/n-3 ratio, and PUFA, using the 1st quintile as reference. Anxiety disorders were identified in 15.4% of the sample. After adjusting for sociodemographic variables, cardiovascular risk factors, diet variables, and depression, intakes in the 5th quintile were inversely associated with anxiety disorders for EPA (OR = 0.82, 95% CI = 0.69-0.98), DHA (OR = 0.83, 95% CI = 0.69-0.98), and DPA (OR = 0.82, 95% CI = 0.69-0.98). Participants in the fifth quintile of n-6/n-3 ratio had a positive association with anxiety disorders. Although results suggest a possible protective effect of n-3 fatty acids against anxiety, all associations lost significance after adjustment for multiple comparisons. |
