Values are medians; ranges in parentheses.
2
Values are hazard ratios; 95% CIs in parentheses.
3
Adjusted for waist circumference, parental history of diabetes, hypertension (≥130/85 mm Hg), low concentrations of HDL cholesterol (<1.04 mmol/L in men or <1.29 mmol/L in women), elevated concentrations of triglycerides (≥1.70 mmol/L), impaired fasting glucose (≥5.6 mmol/L), and Dietary Guidelines for Americans Adherence Index (n = 2956).
4
Adjusted as in model 1 and further adjusted for age and sex (n = 2956).
