Background: Few studies have examined the associations of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) with biomarkers of chronic disease risk in populations with high intakes. Objective: We examined the associations of red blood cell (RBC) EPA and DHA, as percentages of total fatty acids, with biomarkers of chronic disease risk across a wide range of EPA and DHA intakes. Design: In a cross-sectional study of 357 Yup'ik Eskimos, generalized additive models were used to plot covariate-adjusted associations of EPA and DHA with chronic disease biomarkers. Linear regression models were used to test for the statistical significance of these associations. Results: Means (5th–95th percentiles) for RBC EPA and DHA were 2.8% (0.5–5.9%) and 6.8% (3.3–9.0%), respectively. Associations of EPA and DHA were inverse and linear for triglycerides (ß ± SE = –0.10 ± 0.01 and –0.05 ± 0.01, respectively) and positive and linear for HDL cholesterol (ß ± SE = 2.0 ± 0.5 and 0.9 ± 0.6, respectively) and apolipoprotein A-I (ß ± SE = 2.6 ± 0.8 and 1.7 ± 0.8, respectively). Positive linear associations of DHA with LDL and total cholesterol (ß ± SE = 7.5 ± 1.4 and 6.80 ± 1.57, respectively) were observed; for EPA, these associations were nonlinear and restricted to concentrations <5% of total fatty acids. Associations of EPA and DHA with C-reactive protein were inverse and nonlinear: for EPA, the association appeared stronger at concentrations >3% of total fatty acids; for DHA, it was observed only at concentrations >7% of total fatty acids. Conclusion: Increasing EPA and DHA intakes to amounts well above those consumed by the general US population may have strong beneficial effects on chronic disease risk.
