Table 4.

Predictors of latent class membership for past 12-months any nonmedical use of prescription medications (NUPM) class.

	Any NUPM Class (16%)
	OR (95% CI)	AOR (95% CI)
Gender
Female	2.0* (1.6–2.3)	2.2* (1.8–2.7)
Male	—	—
Race/Ethnicity
Caucasian	0.9 (0.7–1.1)	0.9 (0.7–1.2)
Non-Caucasian	—	—
School District
District A	0.9 (0.7–1.02)	0.7 (0.6–0.9)*
District B	—	—
DAST-10 Score	2.0* (1.8–2.2)	1.6* (1.4–1.8)
Any past 12-months alcohol use	3.7* (3.0–4.4)	1.8* (1.4–2.3)
Any past 12-months tobacco use	3.8* (3.2–4.6)	1.3 (0.9–1.7)
Any past 12-months marijuana use	4.0* (3.4–4.9)	1.0 (0.7–1.3)
Any past 12-months illicit drug use	8.9* (6.8–11.6)	2.8* (2.0–4.0)

Note: OR: odds ratio from bivariate logistic regression analysis; AOR: adjusted odds ratio from multiple logistic regression analyses.

The AOR is the multiplicative effect of a predictor variable on the odds of being in the “any NUPM” class when all other variables in Table 4 were statistically controlled.

CI: confidence interval; DAST: Drug Abuse Screening Test.

— = reference group.
