Objective: The aim of this study was to analyze whether omega-3 supplementation improves cardiometabolic profile in individuals with cardiovascular risk factors and to determine the effect of adiponectin levels on these changes. Methods: In this double-blind, placebo-controlled, 2-mo clinical trial, we randomized 80 individuals of both sexes (mean age 52 y) with at least one cardiovascular risk factor (excess weight, hypertension, dyslipidemia, diabetes, or smoking) into two groups: omega-3 (supplemented with 3 g/d of fish oil containing 37% eicosapentaenoic acid and 23% docosahexaenoic acid) and placebo (3 g/d of sunflower oil containing 65% linoleic acid). At baseline and after the intervention, we evaluated serum adiponectin, leptin, lipid profile, apolipoproteins (apo), electronegative low-density lipoprotein (LDL{[}-]), and glucose metabolism (glucose and insulin). Results: After supplementation, the omega-3 group showed an increase in serum adiponectin. After stratifying the omega-3 group by adiponectin concentration at baseline, participants with lower adiponectin concentration showed a higher reduction of total cholesterol, LDL, LDL/high-density lipoprotein ratio, LDL/apo B, and LDL(-). Individuals with a higher variation of adiponectin concentration after omega-3 supplementation presented with reduced blood glucose. The variation of serum adiponectin induced by omega-3 supplementation was negatively correlated with the Framingham and Adult Treatment Panel IV scores (r = -0.4 and P < 0.05 for both). Conclusions: Adiponectin is shown as one of the mechanisms by which omega-3 improves cardiometabolic profile in persons with cardiovascular risk. Moreover, the benefit varies according to the adiponectin basal level and adiponectin variation after supplementation. (C) 2016 Elsevier Inc. All rights reserved. (AU) | |
