Brief Summary

Tobacco use remains a significant public health problem and is increasingly prevalent among vulnerable groups. Appalachians have a high prevalence of tobacco use and are at increased risk for tobacco-attributable diseases. The efficacy of a scientifically valid tobacco cessation treatment delivered to Appalachian smokers remains untested. Also, little is known about the association of social-contextual factors that may modify or mediate the success of an intervention. These factors may be of particular relevance among disadvantaged smokers. Geographical patterns of tobacco exposure may also influence one's ability to quit, especially in pro- tobacco regions like Appalachia. The purposes of this application are to: 1) evaluate the efficacy of a lay-led (LL) intervention in promoting long term abstinence from tobacco; and 2) examine the association between 12 month abstinence and selected individual, interpersonal, organizational, neighborhood and community, and societal factors among adult Appalachian tobacco users exposed to a tobacco cessation intervention. A third aim is exploratory and includes the characterization of activity patterns using space-time measures among adult Appalachian tobacco users exposed to a tobacco cessation intervention. Using a group randomized trial design, 707 Appalachian residents from 6 intervention and 6 control counties will be randomly assigned by county to receive the LL intervention or a control condition which includes proactive telephone counseling via the Ohio Quit Line. LL group participants will receive face-to-face counseling, supervised by a county health department nurse, and delivered by a trained lay educator. A county Extension agent will assist with recruitment and retention efforts in this project. Social-contextual factors will be assessed at a baseline interview administered to all participants. Space-time activity geographical patterns of pro- and anti-tobacco exposures, or features, will be described among selected participants in four counties during weeks 1, 6 and 12 of treatment. At end of treatment and 6 and 12 months, LL and control group participants will be reassessed for tobacco use via self-report and cotinine-validation. Secondary analyses will explore differential trends over time between the two arms of the study. In a subset of the sample, pro- and anti-tobacco exposures will be estimated during weeks 1, 6 and 12 of treatment.

Study Groups

Lay-led tobacco abstinence

Each intervention visit, which lasts an average of 30 minutes, will be delivered face-to-face in a mutually agreed upon convenient location (e.g. participant's home, county extension office). All behavioral and pharmacological intervention strategies will be delivered by the lay educator, with supervision by the county nurse (assigned by county with no overlap between conditions). As recommended by the USPHS guideline, all participants will set a 'quit date' and receive identical behavioral and pharmacological treatment throughout the intervention.

Group Type: OTHER

Lay-led tobacco abstinence

Intervention Type: BEHAVIORAL

Lay-led tobacco abstinence: Each intervention visit, which lasts an average of 30 minutes, will be delivered face-to-face in a mutually agreed upon convenient location (e.g. participant's home, county extension office). All behavioral and pharmacological intervention strategies will be delivered by the lay educator, with supervision by the county nurse (assigned by county with no overlap between conditions). As recommended by the USPHS guideline, all participants will set a 'quit date' and receive identical behavioral and pharmacological treatment throughout the intervention.

Lay-led promotion of Ohio Quit Line

Each participant will be given print information about the Ohio Tobacco QUIT LINE (1-800-QUIT-NOW) and encouraged to call for proactive telephone counseling and free NRT. Proactive telephone counseling and NRT administration will be provided by a QUIT LINE counselor, using their standard protocol.

Group Type: OTHER

Lay-led promotion of Ohio Quit Line

Intervention Type: BEHAVIORAL

Lay-led promotion of Ohio Quit Line (control condition): Each participant will be given print information about the Ohio Tobacco QUIT LINE (1-800-QUIT-NOW) and encouraged to call for proactive telephone counseling and free NRT. Proactive telephone counseling and NRT administration will be provided by a QUIT LINE counselor, using their standard protocol.
