a
A linear trend was tested across the dietary tertiles using the median score of each tertile modeled as a continuous variable.
b
Difference in z score compared with the first tertile.
c
Model 1 adjusted for age, age squared, sex, education, race–field center, total energy intake, and income.
d
Model 2 adjusted for model 1 and apolipoprotein E ε4 status, alcohol use history, smoking history, activity level, body mass index, total cholesterol, prevalent coronary heart disease, and history of hypertension, diabetes, and stroke.
