Impact of Peer and Parental Smoking on the Relationship of Perceived Accessibility and Smoking

	Smoking Events, Hazard Ratio (95% CI)
Characteristics	Initiation (n=1,027)	Regular Smoking (n=1,195)	Progression Among Initiatorsa (n=345)
Perceived accessibility alone	2.06 (1.51–2.81)	4.62 (3.10–6.89)	1.59 (1.07–2.35)
Adjusted for parental smoking only	1.79 (1.31–2.45)	3.76 (2.47–5.73)	1.53 (1.03–2.27)
Adjusted for peer smoking only	1.59 (1.15–2.20)	2.54 (1.68–3.82)	1.26 (0.86–1.86)
Adjusted for both parental and peer smoking	1.44 (1.04–1.99)	2.25 (1.48–3.43)	1.20 (0.81–1.78)

CI = confidence interval.

^a Estimates for this outcome were derived from analyses on initiators, including those who had previously initiated but not progressed to weekly smoking at the date of the baseline interview.
