Note. OR = odds ratio; CI = confidence interval. Model 1: Odds ratios for physical activity were adjusted for age, sex, and current smoking. Odds ratios for medication nonadherence and smoking were adjusted for age and sex. Model 2: Includes additional adjustment for depression. Model 3: Includes additional adjustment for annual income <$20,000.

^aSmoking status (current vs. former vs. never smoker) was entered into an ordinal logistic regression model.

^bThese values represent β values, not odds ratios.

^*p < .05.

^**p < .01.
