Fish Consumption and Omega-3 Polyunsaturated Fatty Acids in Relation to Depressive Episodes: A Cross-Sectional Analysis

摘要: High fish consumption and omega-3 polyunsaturated fatty acid (PUFA) intake are suggested to benefit mental well-being but the current evidence is conflicting. Our aim was evaluate whether a higher level of consumption, PUFAs, serum concentration PUFAs link lower 12-month prevalence depressive episodes.We used data from nationwide Health 2000 Survey (n = 5492) Fishermen Study on Finnish professional fishermen their family members 1265). Data were based questionnaires, interviews, health examinations, blood samples. Depressive episodes assessed with M-CIDI (the Munich version Composite International Diagnostic Interview) self-report two CIDI probe questions, respectively. Fish measured by food frequency questionnaire (g/day) independent questions (times/month). Dietary concentrations (% acids) determined. associated in men not women. The decreased 9% 5% across quartiles (p for linear trend 0.01), from17% 3% (times/month) 0.05). This association modified lifestyle; related who consumed most alcohol, occasional or former smokers, had intermediate physical activity. associations between consistent.In men, appears as surrogate underlying unidentified lifestyle factors that protect against depression.
