Abstract
Background: The feasibility of precision smoking treatment in socioeconomically disadvantaged communities has not been studied.
Methods: Participants in the Southern Community Cohort Study who smoked daily were invited to join a pilot randomized controlled trial of three smoking cessation interventions: guideline-based care (GBC), GBC plus nicotine metabolism-informed care (MIC), and GBC plus counseling guided by a polygenic risk score (PRS) for lung cancer. Feasibility was assessed by rates of study enrollment, engagement, and retention, targeting > 70% for each. Using logistic regression, we also assessed whether feasibility varied by age, sex, race, income, education, and attitudes toward precision smoking treatment.
Results: Of 92 eligible individuals (79.3% Black; 68.2% with household income < $15,000), 67 (72.8%; 95% CI 63.0-80.9%) enrolled and were randomized. Of these, 58 (86.6%; 95% CI 76.4-92.8%) engaged with the intervention, and of these engaged participants, 43 (74.1%; 95% CI 61.6-83.7%) were retained at 6-month follow-up. Conditional on enrollment, older age was associated with lower engagement (OR 0.83, 95% CI 0.73-0.95, p = 0.008). Conditional on engagement, retention was significantly lower in the PRS arm than in the GBC arm (OR 0.18, 95% CI 0.03-1.00, p = 0.050). No other selection effects were observed.
Conclusions: Genetically informed precision smoking cessation interventions are feasible in socioeconomically disadvantaged communities, exhibiting high enrollment, engagement, and retention irrespective of race, sex, income, education, or attitudes toward precision smoking treatment. Future smoking cessation interventions in this population should take steps to engage older people and to sustain participation in interventions that include genetic risk counseling.

期刊介绍：
Addiction Science & Clinical Practice provides a forum for clinically relevant research and perspectives that contribute to improving the quality of care for people with unhealthy alcohol, tobacco, or other drug use and addictive behaviours across a spectrum of clinical settings.
Addiction Science & Clinical Practice accepts articles of clinical relevance related to the prevention and treatment of unhealthy alcohol, tobacco, and other drug use across the spectrum of clinical settings. Topics of interest address issues related to the following: the spectrum of unhealthy use of alcohol, tobacco, and other drugs among the range of affected persons (e.g., not limited by age, race/ethnicity, gender, or sexual orientation); the array of clinical prevention and treatment practices (from health messages, to identification and early intervention, to more extensive interventions including counseling and pharmacotherapy and other management strategies); and identification and management of medical, psychiatric, social, and other health consequences of substance use.
Addiction Science & Clinical Practice is particularly interested in articles that address how to improve the quality of care for people with unhealthy substance use and related conditions as described in the (US) Institute of Medicine report, Improving the Quality of Healthcare for Mental Health and Substance Use Conditions (Washington, DC: National Academies Press, 2006). Such articles address the quality of care and of health services. Although the journal also welcomes submissions that address these conditions in addiction speciality-treatment settings, the journal is particularly interested in including articles that address unhealthy use outside these settings, including experience with novel models of care and outcomes, and outcomes of research-practice collaborations.
Although Addiction Science & Clinical Practice is generally not an outlet for basic science research, we will accept basic science research manuscripts that have clearly described potential clinical relevance and are accessible to audiences outside a narrow laboratory research field.
