Least-squares means and 95%CI were adjusted for age, sex, total energy intake, obesity, physical activity, smoking status, fasting status, total serum cholesterol, measurement year, alcohol intake, and prevalent diabetes.
Intake ranges: EPA (mg/d; Q1:0.0-8.3, Q3:28.7-50.9, Q5:85.6-692.0); DHA (mg/d; Q1:0.1-23.4, Q3:51.3-84.3, Q5:134.5-1061.6); ALA (g/d; Q1:0.19-0.63, Q3:0.83-1.07, Q5:1.46-3.89); LA (en%; Q1:1.2-3.8, Q3: 4.8-5.9, Q5:7.2-19.3).
P-for-trend <0.001 for EPA, DHA, and LA, and 0.80 for ALA.
ALA, alpha-linolenic acid; DHA, docosahexaenoic acid; EPA, eicosapentaenoic acid; FA, fatty acids; LA, linoleic acid.
