RR (95% CI) adjusted for age, race/ethnicity, total energy intake.
RR (95% CI) adjusted for age, race/ethnicity, total energy intake, income, education, smoking, alcohol intake, family history of diabetes, use of postmenopausal hormone therapy, systolic blood pressure, diastolic blood pressure, BMI, and physical activity.
Linear trends were tested by using the median value of each category as an ordinal variable.
