  • Total n = 9,296. The poverty index was determined by the poverty income ratio, which is the total household income in the numerator and a multiple of the total income necessary to maintain a family with a given characteristic on a nutritionally adequate food plan in the denominator.

    * Model 1: crude; model 2: adjusted for age, sex, race, education, and smoking status; model 3: model 2 + BMI, subscapular skinfold, and physical activity level; model 4: model 3 + hypertension and total cholesterol; model 5: model 4 + total caloric intake, total protein, total carbohydrates, and total fat (n = 36 excluded because of missing diet data); model 6: model 4 + poverty index (n = 339 excluded because of missing poverty index data); model 7: model 4 + white blood cell count.
