  1. 1For unstratified analyses, the reference group for race is white and the reference group for region is "other." All models are adjusted for the following covariates: age, total energy, BMI, multivitamin use, menopausal status, hormone therapy use, income, education, marital status, smoking status, alcohol use, physical activity, television viewing, and diagnoses of disease (hypertension, hypercholesterolemia, and diabetes).
  2. 2A significant interaction between race and region was detected for trans fat (p = 0.0014), calcium (p < 0.0001), and cholesterol (p = 0.006). These analyses were stratified by region and beta coefficients represent effects for blacks (referent: white)
