High fish consumption decreased the likelihood of depressive symptoms in community-living older people: a randomized-controlled trial
Background and aims. This study was an attempt to examine the interventional relationship between regular
fish consumption and depression among the elderly, Mashhad, Iran.
Methods. A total of 96 adults who aged 60 years or over was recruited and then divided into groups A and
B. The subjects’ initial eligibility was tested using Beck Depression Inventory (BDI). Group A received fish four
times a week whereas their peers in group B consumed fish two or fewer times per week. The outcome measures
were 12-item general health questionnaire (GHQ-12) and 15-item Geriatric Depression scale (GDS-15).
Results. The results indicated that GHQ and GDS scores decreased non-considerably following three-month
intervention. Fish consumption was associated with a lower likelihood of depression (dichotomized GDS:
OR[odds ratio] = 0.73, 95% CI[confidence interval] = 0.28-1.87, p = 0.618; dichotomized GHQ: OR = 0.67,
95% CI = 0.26-1.73; p = 0.334).
Conclusions. It could be concluded that diet supplementation of the elderly with fish decreased the likelihood
of depressive symptoms. However, this improvement was not statistically significant.
