Chronic disease and recent addiction treatment utilization among alcohol and drug dependent adults

Table 4 Summary of Other Secondary Multivariate Regression Models, with alternate key independent variables (N = 498)

	Model 1	Model 2	Model 3
	Any Addiction Treatment	Outpatient Days	Residential Nights
Key Independent Variable	AOR (95% CI)	IRR (95% CI)	IRR (95% CI)
Asthma	1.05 (0.74, 1.49)	1.03 (0.52, 2.03)	1.03 (0.50, 2.12)
Self-reported health status
Excellent/Very Good/Good	Referent	Referent	Referent
Fair/Poor	0.67 (0.48, 0.94)*	0.40 (0.20, 0.80)**	0.61 (0.31, 1.21)
Physical Component Score (per 1 point increase)	1.01 (0.99, 1.03)	1.00 (0.97, 1.04)	1.01 (0.97, 1.04)

Model 1 used logistic regression; Models 2 and 3 used Poisson regression. Models duplicate those in Table 3 (controlling for age, gender, race, substance dependence, recruitment from detox, criminal justice involvement, homeless, unemployed, health insurance, smoker, anxiety), solely replacing the chronic disease variable with the secondary variables above.
