Effects on wave 2 suicide-related outcomes (SRO) according to smoking status change as reported in NESARC wave 1 and wave 2 interviews

Smoking status in wave 1 to wave 2	n/N	Weighted percentage* (SE)	Wave 2 SRO†
			AOR‡ (95% CI)
1. Consistent never smoker (in wave 1 and wave 2)	897/3653	47.8 (0.40)	1.00
2. Long-term former smoker (in wave 1 and wave 2)	293/1185	16.4 (0.26)	1.22 (1.12 to 1.34)
3. Recent former smoker (current smoker in wave 1, former smoker in wave 2)	126/393	5.3 (0.14)	1.37 (1.16 to 1.63)
4. Persistent current smoker (in wave 1 and wave 2)	683/1824	26.3 (0.35)	1.50 (1.35 to 1.66)
5. New current smoker (never smoker in wave 1, current smoker in wave 2)	82/194	2.6 (0.10)	1.82 (1.51 to 2.19)
6. Relapser (former smoker in wave 1, current smoker in wave 2)	46/95	1.5 (0.08)	3.42 (2.85 to 4.11)
	N=7352§

^*The sampling weight variable in wave 2 was used.

^†Any of three items: want to die, suicidal ideation, suicide attempt.

^‡AORs are adjusted OR with 95% CIs based on multiple logistic regression of wave 2 SRO as a function of age, sex, race/ethnicity, marital status, income, education, unemployed status, Census region, urban residence, smoking status, Axis I and Axis II disorders (as described in text) and lifetime SRO reported in wave 1.

^§The seventh group (n=8), which consisted of persons who were never smokers in wave 1, began to smoke and then stopped smoking in wave 2, was too small for a valid assessment of risk.
