Stratified analyses were adjusted for age, sex, race, education, PIR, BMI, waist circumference, smoking status, alcohol intake, diabetes mellitus, hypertension, stroke, CHD, and depression scores. BMI, body mass index; CHD, coronary heart disease; PIR, family income-to-poverty ratio; VLSFAs, very long-chain saturated fatty acids
