Overall: inactive	3.0	[1.4–6.4]**	0.71	[0.38–1.3]
Light exercise: inactive	2.5	[1.2–5.4]*	0.68	[0.34–1.4]
Moderate exercise: inactive	2.0	[0.91–4.2]	0.87	[0.47–1.5]
Heavy exercise: inactive	1.1	[0.38–3.3]	1.1	[0.47–2.5]
Compared to others: inactive	1.5	[0.69–3.4]	1.2	[0.64–2.2]

Mean smoking pack years	β = 8.9b	[1.9–15.9]**	β = 8.9b	[1.9–15.9]**

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 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.
