PRIMARY outcome

Timeframe: 6 months

Population: The difference in the "overall number of participants analyzed, "from the "number analyzed," in the ANBL arm, is due to missing data.

The primary outcome of the study was salivary cotinine-verified 7-day point prevalence smoking abstinence at 6 months (Have you smoked at least part of a cigarette in the past 7 days?) using responders-only analyses.

Measure
Experimental 1: All Nations Breath of Life Program (ANBL)
n=243 participants at risk
All participants in the proposed study will be offered pharmacotherapy (e.g. Varenicline, Bupropion, or NRT) then randomized into either the culturally-tailored "All Nations Breath of Life" program (ANBL) or Nontailored program (NT). Experimental 1: All Nations Breath of Life program (ANBL): ANBL consists of in-person group sessions and individual telephone calls. We have successfully conducted a pilot study of ANBL and have found very promising results. At six months and 12 months post baseline, all participants will be assessed for smoking status and smoking abstinence. Pharmacotherapy (e.g. Varenicline or Bupropion or NRT): Pharmacotherapy (e.g. Varenicline or Bupropion or NRT)
Experimental 2: Nontailored Program (NT)
n=220 participants at risk
All participants in the proposed study will be offered pharmacotherapy (e.g. Varenicline, Bupropion, or NRT) then randomized into either the culturally-tailored "All Nations Breath of Life" program (ANBL) or Nontailored program (NT). Experimental 2: Nontailored program (NT): The nontailored intervention includes the medicines listed above to all participants and targeted counseling delivered by non-American Indian counselors who have worked closely with the American Indian communities and respect the cultures, values, and traditions of the Indian people. Therefore, our intervention includes the current "best practice" recommendations for smoking cessation. At six months and 12 months post baseline, all participants will be assessed for smoking status and smoking abstinence. Pharmacotherapy (e.g. Varenicline or Bupropion or NRT): Pharmacotherapy (e.g. Varenicline or Bupropion or NRT)
