  • Quitting Behaviors Among Dual Cigarette and E-Cigarette Users and Cigarette Smokers Enrolled in the Tobacco User Adult Cohort

    by Laura Sweet, Theodore M Brasky, Sarah Cooper, Nathan Doogan, Alice Hinton, Elizabeth G Klein, Haikady Nagaraja, Amanda Quisenberry, Wenna Xi, Mary Ellen Wewers

    We examined quitting behaviors among a cohort of dual users (cigarettes and electronic cigarettes [e-cigarettes]) and exclusive cigarette smokers for: (1) cigarette smoking reduction, (2) quit attempts, (3) abstinence from cigarettes, and (4) abstinence from all tobacco products. Participants enrolled in the Tobacco User Adult Cohort and categorized as “daily” user of cigarettes and “daily” or “some days per week” use of e-cigarettes (ie, dual users; n = 88) or “daily” user of cigarettes only (ie, cigarette smokers; n = 617) served as the analytic sample. Participants were interviewed face to face every 6 months, through 18 months. Data on self-reported current product(s) used, cessation interest, quit attempts and abstinence from cigarettes, and all tobacco products were collected. No difference in reduction of cigarette consumption over time was noted between groups. Rates of reporting an attempt to quit all tobacco products (≥ 24 hours of not using any tobacco in an attempt to quit) also did not differ by group. Compared to cigarette smokers, dual users were more likely to report abstinence from cigarettes at 6 months (OR = 2.54, p = .045) but not at 12 or 18 months. There was no significant difference in abstinence from all tobacco products by group at 6, 12, or 18 months. Although dual use of e-cigarettes has been cited as a potential cessation tool for cigarette smokers, our findings indicated that this association was only observed in the short term. We also found no evidence of any association between dual use and eventual abstinence from all tobacco products. Our study observed that, in the natural environment, dual users of cigarettes and e-cigarettes were more likely than cigarette smokers to quit cigarettes in the short term but no more likely to quit using cigarettes and all tobacco products over time.

    A Descriptive Report of Electronic Cigarette Use After Participation in a Community-Based Tobacco Cessation Trial

    by Elana Curry, Julianna M Nemeth, Amy Wermert, Sara Conroy, Abigail Shoben, Amy K Ferketich, Mary Ellen Wewers

    Smokers are using electronic cigarettes, also known as e-cigarettes, as a cessation aid, despite uncertainty about their efficacy. This report describes the association between use of e-cigarettes before and after cessation treatment and tobacco abstinence at 12 months. It also presents characteristics of e-cigarette users and reasons for use. A longitudinal observational secondary analysis of self-reported e-cigarette use was conducted among adult Appalachian smokers enrolled in a community-based tobacco dependence treatment trial (n = 217). Data were collected at baseline, 3, 6, and 12 months following treatment. The primary outcome measure was biochemically-confirmed 7-day point prevalence tobacco abstinence at 12 months post-treatment. One in five participants reported using e-cigarettes post-treatment. Baseline sociodemographic and tobacco-related characteristics did not differ by e-cigarette use. Primary reasons for e-cigarette use included help in quitting, help in cutting down on cigarettes, and not as bad for health. At the 12 month follow-up, tobacco abstinence was significantly lower among post-treatment e-cigarette users (4.7%) than nonusers (19.0%); (OR = 0.21 95% CI: 0.05–0.91, p = .021). Baseline use was not associated with 12-month abstinence. Among adult Appalachian smokers enrolled in community-based tobacco cessation treatment, use of e-cigarettes post-treatment was associated with lower abstinence rates at 12 months. This descriptive report of electronic cigarette use after participation in a community-based group randomized tobacco dependence treatment trial adds to the body of science examining e-cigarette use and cessation. Post-treatment e-cigarette use was associated with less success in achieving abstinence at 12 months, as compared to nonuse. At 3 months post-treatment, the majority of those who reported use of e-cigarettes did so to assist with cessation.


  • Depression, smoking, and ego-centric social network characteristics in Ohio Appalachian women.

    by Jeffrey A. Lam, Bo Lu, Nathan J. Doogan, Tiffany Thomson, Amy Ferketich, Electra D. Paskett, Mary Ellen Wewers

    Depression is a serious, costly, and debilitating disorder that is understudied in rural women. Studies show that depression is associated with low social integration and support, but few studies investigate the relationship between depression and social network characteristics. This study examined the associations among women from three Ohio Appalachian counties enrolled in a health study, which aimed to collect information for a future social network smoking cessation intervention. An address-based sampling method was used to randomly select and recruit 404 women. A cross-sectional survey and interview were used to collect information about demographic, psychosocial, behavioral factors, and ego-centric social network characteristics, which are variables derived from an individual (ego) and her first degree contacts (alters). The CES-D scale assessed depressive symptoms. A multivariable logistic regression analysis described the association between these factors and participants with depression (defined as CES-D≥16). Higher network density, or greater number of relationships among alters divided by the total amount of alters, reduced the risk for depression (OR = 0.84, 95% confidence interval [CI] 0.73-0.95). Additionally, women with a high percentage of smoking alters were at greater risk for depression (OR = 1.19, 95% CI 1.02-1.39). Other factors associated with risk for depression included perceived stress score (OR = 1.34, 95% CI 1.24-1.45), loneliness score (OR = 1.37, 95% CI 1.05-1.80), and days with poor physical health (OR = 1.06, 95% CI 1.02-1.11). Findings suggest that psychosocial factors and social networks should be considered when addressing depression in clinical practice.

    Effectiveness of Two Community Health Worker Models of Tobacco Dependence Treatment Among Community Residents of Ohio Appalachia

    by Mary Ellen Wewers, Abigail Shoben, Sara Conroy, Elana Curry, Amy K. Ferketich, David M. Murray, Julianna Nemeth, Amy Wermert

    Community health workers (CHW) may be effective in the delivery of tobacco dependence treatment with underserved groups. This study evaluated two evidence-based CHW models of treatment. It was hypothesized that smokers assigned to a CHW face-to-face condition would have higher abstinence at 12-month posttreatment than smokers enrolled in CHW referral to a state-sponsored quitline condition. Intrapersonal and treatment-related factors associated with abstinence at 12 months were determined. A group-randomized trial was conducted with residents of 12 Ohio Appalachian counties with counties (n = 6) randomized to either a CHW face-to-face (F2F) or CHW quitline (QL) condition. Both conditions included behavioral counseling and free nicotine replacement therapy for 8 weeks. Follow-up data were collected at 3-, 6-, and 12-month posttreatment. Biochemically validated abstinence at 12 months served as the primary outcome. Seven hundred and seven participants were enrolled (n = 353 CHWF2F; n = 354 CHWQL). Baseline sample characteristics did not differ by condition. Using an intent-to-treat analysis (85.4% retention at 12 months), 13.3% of CHWF2F participants were abstinent at 12 months, compared to 10.7% of CHWQL members (OR = 1.28; 95% confidence interval [CI] = 0.810, 2.014; p = .292). No differences in abstinence were noted at 3 or 6 months by condition. Age, marital status, and baseline levels of cigarette consumption, depressive symptoms, and self-efficacy for quitting in positive settings were associated with abstinence, as was counseling dose during treatment. This research adds to the body of science evaluating the effectiveness of CHW models of tobacco dependence treatment. Both approaches may offer promise in low-resource settings and underserved regions. This 12-county community-based group–randomized trial in Ohio Appalachia adds to the body of science evaluating the effectiveness of CHW models of tobacco dependence treatment. Both CHW approaches may offer promise in low-resource settings and underserved regions. These findings are useful to national, state, and local tobacco control agencies, as they expand delivery of preventive health care services postadoption of the Affordable Care Act in the United States.


  • Risk Perceptions of Smokeless Tobacco Among Adolescent and Adult Users and Nonusers

    by Sherry T. Liu, Julianna M. Nemeth, Elizabeth G. Klein, Amy K. Ferketich, Mei-Po Kwan, Mary Ellen Wewers

    The recent growth in smokeless tobacco (ST) consumption has raised questions about consumer risk perceptions of ST products, especially in high-risk vulnerable populations. This qualitative study examined risk perceptions of ST among adolescent and adult users and nonusers in Ohio Appalachia. Focus groups and interviews were held with adolescents (n = 53; M age = 17 years) and adults (n = 63; M age = 34 years) from four Ohio Appalachian counties. Participants were asked about their perceptions of ST-related health risks, ST safety, and the relative safety of ST compared with cigarettes. Transcriptions were coded independently by two individuals. Overall, participants were knowledgeable about health problems from ST use (e.g., oral cancers, periodontal disease). Nearly all participants stated that ST use is not safe; however, there was disagreement about its relative safety. Some perceived all tobacco products as equally harmful; others believed that ST is safer than cigarettes for either the user or those around the user. Disagreements about ST relative safety may reflect mixed public health messages concerning the safety of ST. Comprehensive consumer messages about the relative safety of ST compared with cigarettes are needed. Messages should address the effect of ST on the health of the user as well as those exposed to the user.

  • Adolescent and adult perceptions of traditional and novel smokeless tobacco products and packaging in rural Ohio

    by Sherry T Liu, Julianna M Nemeth, Elizabeth G Klein, Amy K Ferketich, Mei-Po Kwan, Mary Ellen Wewers

    Objective As smokeless tobacco (ST) marketing increases and new products emerge on the market, very little is known about consumer perceptions of ST products. To inform development of future ST counter-marketing approaches, this qualitative study examined consumer perceptions of traditional and novel ST products and packaging. Methods Focus groups and qualitative interviews were held with adolescent (n=23; mean age of 17 years) and adult (n=38; mean age of 29 years) male ST users from rural Ohio counties. Participants were shown a variety of traditional (eg, Copenhagen, Timber Wolf) and novel (eg, Camel Snus, Orbs) ST products and asked about perceptions of these products and their packaging. Transcriptions were coded independently for common themes by two individuals. Findings Adolescents and adults generally had similar beliefs and reactions about ST products. While participants were familiar with a variety of traditional ST products, Copenhagen was the most frequently used product. Perceptions of quality and price of traditional products were closely tied to product taste and packaging material. Colours, design and size of ST packaging appealed to participants and influenced decisions to purchase. Adults believed novel ST products had a weak taste and were targeted at untraditional ST users. While the vast majority was unfamiliar with dissolvable tobacco, adolescents noted that they would be more convenient to use during school than traditional ST. Conclusions Packaging has a significant role in shaping perceptions of ST and consumer behaviour. Regulation of product packaging such as shape, size and images should be part of comprehensive tobacco control.


  • Risk Factors for Smoking in Rural Women

    by Mary Ellen Wewers, Pamela J. Salsberry, Amy K. Ferketich, Karen L. Ahijevych, Nancy E. Hood, Electra D. Paskett

    This study examined the association between social, demographic, and psychologic factors and smoking status among Appalachian Ohio women. A secondary aim examined whether specific factors could be identified and segmented for future tailored treatment of tobacco dependence. A cross-sectional survey (n=570) obtained information about social, demographic, and psychologic factors and smoking. Logistic regression described associations between these characteristics and smoking status. Chi-square automatic interaction detection (CHAID) analyses identified subgroups at risk for smoking. Fifty-two percent never smoked, with 20.5% and 27.5% categorized as former and current smokers, respectively. Women with low adult socioeconomic position (SEP) were more likely to smoke (odds ratio [OR] 3.05, 95% confidence interval [CI] 1.74-5.34) compared to high SEP women. Other factors associated with current smoking included age 31-50 (OR 2.30, 95% CI 1.22-4.33), age 18-30 (OR 3.29, 95% CI 1.72-5.34), Center for Epidemiologic Studies Depression scale (CES-D) score≥16 (OR 1.99, 95% CI 1.31-3.05), and first pregnancy at age<20 (OR 1.74, 95% CI 1.14-2.66). The prevalence of smoking was 50% among those with four or more risk factors compared to 10% for those reporting no risk factors. CHAID analyses identified low adult SEP and depressive symptoms as the combination of risk factors most strongly associated with smoking; 49.3% of women in this subgroup currently smoked. Low SEP in adulthood, maternal circumstances, and depressive symptoms are associated with current smoking. Tailored cessation interventions that address these risk factors should be developed and further evaluated in an attempt to reduce disparities in smoking prevalence among this vulnerable group of women.


  • Factors Influencing Smokeless Tobacco Use in Rural Ohio Appalachia

    by Julianna M. Nemeth, Sherry T. Liu, Elizabeth G. Klein, Amy K. Ferketich, Mei-Po Kwan, Mary Ellen Wewers

    The burden of smokeless tobacco (ST) use disproportionally impacts males in rural Ohio Appalachia. The purpose of this study was to describe the cultural factors contributing to this disparity and to articulate the way in which culture, through interpersonal factors (i.e. social norms and social networks) and community factors (i.e. marketing and availability), impacts ST initiation and use of ST among boys and men in Ohio Appalachia. Fifteen focus groups and 23 individual qualitative interviews were conducted with adult (n = 63) and adolescent (n = 53) residents in Ohio Appalachian counties to ascertain factors associated with ST use and the impact of ST marketing. Transcriptions were independently coded according to questions and themes. ST use appears to be a rite of passage in the development of masculine identity in Ohio Appalachian culture. Interpersonal factors had the greatest influence on initiation and continued use of ST. Ohio Appalachian boys either emulated current ST users or were actively encouraged to use ST through male family and peer networks. Users perceived their acceptance into the male social network as predicated on ST use. Community factors, including ST advertisement and access to ST, reinforced and normalized underlying cultural values. In addition to policy aimed at reducing tobacco marketing and access, interventions designed to reduce ST use in Ohio Appalachia should incorporate efforts to (1) shift the perception of cultural norms regarding ST use and (2) address male social networks as vehicles in ST initiation.
