Depression and health-related quality of life (HRQoL) are closely interrelated among hemodialysis (HD) patients and associated with negative impacts on patients' clinical outcomes. Considering previous reports on clinical benefits of omega-3 fatty acids in major depression and HRQoL in other patient populations, this study examined effects of omega-3 fatty acids on depression and HRQoL in chronic HD patients. In this randomized placebo-controlled trial, 40 adult patients with a Beck Depression Inventory (BDI) score of ≥16 and HD vintage of at least 3 months were randomized to ingest 6 soft-gel capsules of either omega-3 fatty acids (180 mg eicosapentaenoic acid and 120 mg docosahexaenoic acid in each capsule) or corresponding placebo, daily for 4 months. At baseline and after 4 months, 2 questionnaires of BDI and the Medical Outcome Study 36-Item Short-Form Health Survey were completed by each patient. Although baseline BDI score was comparable between the 2 groups, it was significantly lower in the omega-3 group compared with the placebo group at the end of the study (P = 0.008). Except for mental health, social functioning, and general health, other domains of HRQoL showed significant improvement in the omega-3 group compared with the placebo group at month 4 of the study (P < 0.05 for all). Regression analysis revealed that ameliorated BDI score by omega-3 treatment had considerable role in the improvement of overall HRQoL score, physical and mental component dimensions, a...
