Mean ± SE values were determined by using linear regression with robust variance estimators and adjusted for age (y), sex, race-ethnicity (white, black, Hispanic, Chinese), education (<high school, high school, some college, college graduate), field center (6 sites), smoking status (never, former, current), prevalent diabetes (yes, no), alcohol use (drinks/wk), physical activity (metabolic equivalent min/wk), BMI (kg/m2), and waist circumference (cm). To convert LDL cholesterol and HDL cholesterol from mg/dL to mmol/L, divide by 38.67. To convert triglycerides from mg/dL to mmol/L, divide by 88.57. To convert glucose from mg/dL to mmol/L, divide by 18.0. MESA, Multi-Ethnic Study of Atherosclerosis.
The numbers of participants with available measures for each biomarker are shown.
Tests for trend (monotonic dose-response) across quintiles were performed by assigning each participant the median fatty acid value in his or her quintile and modeling this variable as a continuous term.
Values are medians; ranges in parentheses.
