  • Cox proportional hazard models adjusted for age, gender, race/ethnicity, education, smoking, physical activity and energy intake. Separate models were developed for each dietary pattern and weight category. Dietary categories (low and high) are based on tertiles of native score. The lowest tertile is the reference group. Weight categories were based on BMI (normal: 18.5–<25 kg/m2; overweight: 25–<30 kg/m2; obese: ≥30 kg/m2).
