Odds ratios (ORs) of DSM-IV nicotine dependence by body mass index (BMI) category for males and females.

	Male		Male Only	Female		Female Only	Interaction

	Overweight BMI=25.00–29.99	Obese BMI ≥ 30.00	F (df=2)	Overweight BMI=25.00–29.99	Obese BMI≥ 30.00	F (df=2)	F (df=2)
Nicotine Dependence
Lifetime, OR	0.77	0.83	11.01, p<.001	1.16	1.01	3.26, p<.05	10.48, p <.001
(95% C.I.)	(0.69–0.87)^*	(0.73–0.94)^*		(1.03–1.31)^*	(0.90–1.14)
Past Year, OR	0.71	0.74	17.28, p<.001	1.09	0.84	5.59, p<.01	9.21, p <.001
(95% C.I.)	(0.63–0.81)^*	(0.64–0.86)^*		(0.94–1.27)	(0.73–0.96)^*

Wald F values report effect of BMI on likelihood of substance use disorder within gender and effect of the interaction of BMI and gender on likelihood of substance use disorder in the total sample. Odds ratios (ORs) obtained using normal weight as reference group. Normal weight and male gender are comparators for interactions. Analyses control for age, level of education, race/ethnicity, income, marital status, region of country, urban vs. rural residence, and lifetime and past-year DSM-IV diagnoses of any mood disorder, any anxiety disorder, any personality disorder, any alcohol use disorder, and any drug use disorder.

Indicates that Wald F is significant, and OR is significantly different from 1.00 within that gender.
