Abstract

Background n-3 Fatty acids lower blood pressure, improve lipids, and benefit other cardiovascular disease risk factors. Effects on glycemia in patients with type 2 diabetes are uncertain.Objective We determined whether purified eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have differential effects on glycemic control, including insulin sensitivity and stimulated insulin secretion; 24-h ambulatory blood pressure; and serum lipids in type 2 diabetic patients with treated hypertension.Design In a double-blind, placebo-controlled trial of parallel design, 59 subjects were randomly assigned to consume 4 g EPA, DHA, or olive oil/d for 6 wk while continuing to consume their usual diet.Results Thirty-nine men and 12 postmenopausal women with a mean (+/- SE) age of 61.2 +/- 1.2 y completed the study. In comparison with the change from baseline in fasting glucose in the olive oil group, fasting glucose in the EPA and DHA groups increased 1.40 +/- 0.29 mmol/L (P = 0.002) and 0.98 +/- 0.29 mmol/L (P = 0.002), respectively. Neither EPA nor DHA had significant effects on glycated hemoglobin, fasting insulin or C-peptide, insulin sensitivity or secretion, or blood pressure. Serum triacylglycerols in the EPA and DHA groups decreased 19% (P = 0.022) and 15% (P = 0.022), respectively. There were no significant changes in serum total, LDL, or HDL cholesterol, although HDL(2) cholesterol in the EPA and DHA groups increased 16% (P = 0.026) and 12% (P = 0.05), respectively. HDL(3) cholesterol decreased 11% (P = 0.026) with EPA supplementation.Conclusions EPA and DHA had similar benefits on lipids but adverse effects on short-term glycemic control in hypertensive diabetic patients. The overall implications for cardiovascular disease require long-term evaluation.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
