Regression results for AL and 25(OH)D concentration.

For logistic regression AL, allostatic load, was included as a binary variable (high or low). For Poisson regression AL, allostatic load, was included as count of the numbers of biomarkers at risk; 25(OH)D, serum 25-hydroxyvitamin D concentration. AL was the only variable considered for the basic, unadjusted model. As „biological”factors age, sex and race/ethnicity were included, “socioeconomic” variables comprised education, census region, urbanization, marital status, poverty-income ratio, “lifestyle” factors alcohol consumption, smoking status, physical activity, diet. Additionally, self-reported general health was added to the full model. Regression results for AL and 25(OH)D concentration.
