Abstract

ABSTRACT Objective To assess the effect of omega-3 supplementation on smokers' high density lipoprotein subfractions. Methods This randomized, double-blind clinical trial included 33 male and female smokers aged 30 to 60 years. The sample took omega-3 fatty acids (n=17) or placebo (omega-6 fatty acids, n=16) for two months. The Lipoprint system analyzed the high density lipoprotein subfractions. The statistical tests were performed by the software Statistical Package for the Social Sciences, version 20.0. Results The mean age of the sample was 49 years, and most individuals were white. After the intervention, the lipid profile and high density lipoprotein subfractions of the omega-3 group improved. In the tested linear regression models, the percentage of plasma docosahexaenoic acid was negatively associated with the percentage of small high density lipoprotein. Conclusion Omega-3 supplementation is associated with a favorable change in the distribution of high density lipoprotein subfractions, increasing the large and reducing the small high density lipoproteins. This finding reinforces the importance of omega-3 fatty acids for smokers' cardiovascular health. (AU)
