Multivariate model 1 adjusted for age, sex, dialect, and year of interview; multivariate model 2 further adjusted for educational level, BMI, physical activity, smoking duration, cigarette smoking per day, alcohol use, baseline history of self-reported diabetes, hypertension, coronary heart disease, stroke, and total energy intake; multivariate model 3 further adjusted for dietary fiber, SFAs, MUFAs, ω-3 PUFAs, and ω-6 PUFAs.
Linear trend was tested by treating the quartile as a continuous variable.
