Tobacco use is the leading cause of cancer death in the U.S. Because smokers who quit by age 30 have cancer death risk similar to non-smokers, promoting cessation early in life is critical. U.S. colleges/universities, enrolling >14 million students/year (40% of those aged 18 to 24), are an important venue to reach young adult smokers. While daily tobacco use in the U.S. has declined to 18.1%, nondaily smoking (smoking on some days but not every day) is increasing, particularly among young adults and African Americans. Moreover, young smokers and nondaily smokers (half of young adult smokers), respectively, are less likely to seek help in quitting; thus, innovative strategies are needed to assist cessation early in life, particularly among those who may not be motivated to quit or seek help. Unfortunately, no research has focused on developing a cessation intervention that addresses a broad range of smoking patterns (nondaily to daily smoking) or diverse campus settings among ethnically diverse student populations. Web-based interventions offer promise in helping college students to quit, given high rates of Internet use and web capacity to provide tailored cessation messages. A novel approach to delivering cessation information via the web might be to address broader lifestyle issues and apply market research strategies to identify market segments of smokers (groups of people with similar interests, goals, values) in order to target and engage these groups more effectively. Applying this strategy to an online cessation intervention should enhance both intervention use and processing of intervention messages, leading to greater abstinence rates. The investigators aim to: (1) develop and refine a tailored web-based intervention for smoking cessation targeting college students with a range of smoking levels; (2) test the usability, acceptability, and feasibility of the intervention among college student smokers; and (3) determine the potential effect of the intervention on smoking cessation, smoking level, quit attempts, and contextual factors.
The purpose of this study is to determine whether resistance training can aid smoking cessation.
The goal of this research study is to enhance smoking cessation rates for homeless smokers. The original study design proposed to test the effects of 1) an Intensive Smoking Intervention, and 2) integrating alcohol abuse treatment with smoking cessation We will utilize a 3-group randomized design to test study hypotheses. The three study conditions are 1) Integrated Intensive Smoking plus Alcohol intervention using cognitive behavioral therapy (CBT), CBT-(IS+A); 2) Intensive Smoking Intervention using CBT-(IS); or 3) Usual Care (brief smoking cessation and brief alcohol counseling both based on the United States Public Health Service's Guidelines)-(UC). Due to low enrollment because of the addition of an alcohol use screening criteria, the study was changed to a two arm study and the study time frame changed. The two study conditions are 1) Integrated Intensive Smoking plus Alcohol intervention using cognitive behavioral therapy (CBT), CBT-(IS+A) and 2) Usual Care (brief smoking cessation and brief alcohol counseling both based on the United States Public Health Service's Guidelines)-(UC). The study length is reduced to 26 weeks from 52 weeks. All participants will receive 12-week treatment with nicotine patch plus nicotine gum/lozenge. Counseling will follows the protocol used in a recent study of alcohol dependent smokers and will include weekly individual sessions for 3 months followed by study data collection visits 3 months. Both study conditions will have equal number of study contacts. Study staff will make retention contacts with participants in the community during weeks that do not have study visits scheduled. Primary smoking outcome is cotinine-verified 7-day smoking abstinence at week 26 follow-up while secondary outcome is prolonged smoking abstinence at weeks 12, 16, and 26. Secondary alcohol outcome will be self-reported continuous alcohol abstinence for 90 days at week 26. Recruitment and retention will be enhanced by use of gift cards, bus passes, other non-monetary incentives, attractive intervention materials, collaboration with homeless shelters, and advice from a Community Advisory Board. Participants will be enrolled from homeless shelters and facilities in the 7-county greater Minneapolis/St. Paul metro area. Our power calculation indicates that a sample size of 215 per study condition is needed to detect proposed treatment effects.
This study was conducted to develop biomarkers of tobacco effect that would indicate potential harm related to tobacco consumption. To gain a better understanding of chronic effects of tobacco consumption, this cross-sectional clinical study enrolled generally healthy, adult male consumers of cigarettes (SMK), moist snuff (MSC), and no tobacco products (NTC).
Background: - Researchers want to see how well the QuitTXT text-message program helps smokers ages 18 29 stop smoking. This is part of a larger online stop-smoking program by the National Cancer Institute. The QuitTXT program is a 2-week countdown to the smoker s quit date with 6 weeks of follow-up messages. Program participants will receive texts on their cell phones, including tips, information, and motivational messages, and then fill out surveys. Objectives: - To study how well the QuitTXT program helps smokers ages 18 29 stop smoking. Eligibility: - Adults ages 18 29 who have smoked on at least 5 of the past 30 days and who want to stop smoking in the next 30 days. Design: - Participants will receive a certain number of text messages during the 8-week study. They will receive between 0 to 5 messages per day (or up to a total of 130 messages). - Participants will first fill out a survey about their smoking and quitting experiences. Then they will choose a date to quit smoking (a quit date ) between 2 and 3 weeks after this survey. - Participants will take four other surveys online, one during the program and three more after they ve completed the program. Each survey will take about 10 20 minutes and asks about their smoking habits and views on smoking and quitting. Each survey will be sent by email, with reminders sent by email or telephone. - Participants will receive an iTunes or Amazon gift card for completing each survey honestly.
This randomized controlled trial compares the effectiveness for both smoking cessation and weight control of two alternative combined interventions offered via telephone quitline, as compared to standard of care quitline treatment addressing cessation alone. The interventions to be compared are cessation treatment alone versus cessation treatment combined with weight control treatment added either simultaneously or sequentially.
Innovative strategies to reduce adult smoking prevalence include using genetic information to motivate cessation and, ultimately, to tailor cessation pharmacotherapy. Success of these interventions depends, in part, on smokers' interest and participation in genetic testing related to cessation and their understanding and use of the results (i.e., their genetic literacy). The recent availability of genetic risk testing for a nicotinic acetylcholine receptor gene (CHRNA3) variant (rs105173) associated with nicotine dependence makes it highly feasible to investigate smokers' interest in and use of genetic information about nicotine dependence. Therefore, the primary purpose of this study is to determine the impact of an intervention that provides smokers with an educational session about genetic contributions to smoking and nicotine dependence plus their genotype results for rs1051730 on smoking cessation outcomes compared to those who receive only the educational session. Secondary purposes are to determine: (a) the impact of genetic education and knowing personal genotype results on genetic literacy outcomes and (b) the feasibility of recruitment and retention methods in a study addressing genotyping for nicotine dependence. Primary outcomes are cessation-related behaviors and cognitions indicating abstinence. Secondary outcomes are cognitions and emotions indicating genetic literacy. Knowledge gained from this study has the potential for clinical translation so that as genotyping becomes part of smoking cessation, health-care providers can understand and address factors influencing smokers' adaptation to genetically-informed cessation treatment. The study will use a longitudinal, repeated measures design (experimental, control; N=90; 45/group). All participants will receive a 90-minute educational session about genetic contributions for smoking and nicotine dependence and will donate a buccal swab sample for genotyping. The investigators will then randomize participants to two groups: those who receive genotyping results in a genetic counseling session (experimental) and those who do not (control). Follow-up data will be collected from both groups at baseline and weeks 2, 6, 10 after the experimental group receives genotyping results, with a brief follow-up and study termination occurring at week 12. Control group participants will be offered their genotyping results at the end of the study.
Smoking cessation services are an unmet need among the homeless, who smoke at rates more than 3 times the national estimate; successful interventions in this underserved population have the potential for improving individual and public health. Contingency management (CM) is a behavioral intervention with efficacy in a number of substance use disorder populations, including smokers. However, no known studies have evaluated the effect of CM in homeless smokers. The investigators plan to examine smoking-related outcomes in homeless treatment-seeking smokers (N = 70) randomized to standard care smoking cessation (transdermal nicotine replacement therapy [NRT] + standard counseling + carbon monoxide [CO] monitoring) or standard care plus CM (NRT + standard counseling + CO monitoring + CM) conditions. Standard counseling and CO monitoring will occur for the first 4 weeks, with NRT use continuing through week 8. Participants in both conditions will meet with study staff up to twice daily on weekdays for biochemical verification of smoking status. Participants in the CM condition will have the opportunity to earn prizes for negative breath samples (CO ≤ 4 ppm) up to twice daily on weekdays. CO breath samples will be collected at all visits. The investigators expect that participants randomized to CM will have better outcomes compared to those in standard care.
Cigarette smoking is the leading preventable cause of death in the U.S. The 2008 US Public Health Service Smoking Cessation Guideline recommends offering effective treatment to smokers in all health care settings, including hospitals. Nearly 4 million smokers are hospitalized each year, and hospital admission offers a "teachable moment" for intervention. Hospital-initiated smoking cessation intervention is effective, but only if contact continues for more than 1 month after discharge. The challenge is to translate this research into clinical practice by identifying an evidence-based cost-effective model that U.S. hospitals can adopt. The major barrier is sustaining contact after discharge. This project tests an innovative strategy to streamline the delivery and maximize the uptake of post-discharge smoking interventions. Specific Aim: To test the effectiveness of an innovative strategy to maximize smokers' use of evidence-based tobacco treatment (counseling and medication) after hospital discharge, thereby increasing the proportion of smokers who achieve long-term (6-month) tobacco abstinence. Study Design: A multi-site randomized controlled comparative effectiveness trial will enroll 1350 adult smokers admitted to 3 acute care hospitals in Massachusetts and Pennsylvania. All subjects will receive a brief in-hospital smoking intervention and be randomly assigned at discharge to either Standard Care (passive referral to their state quitline) or Extended Care, a 3-month program consisting of (1) Free Medication: A 30-day supply of FDA-approved medication (nicotine replacement, bupropion, or varenicline) given at hospital discharge and refillable for a total of 90 days to encourage medication use and adherence; (2) Interactive Voice Response (IVR) Triage to Telephone Counseling from a national quitline provider. IVR aims to encourage medication adherence and enhance counseling efficiency by identifying smokers who need post-discharge support. Immediate transfer of a patient from automated IVR call to live telephone counselor will facilitate a successful connection to counseling. Outcomes, assessed at 1, 3, and 6 months after hospital discharge, are: (1) intervention effectiveness (cotinine-validated 7-day point-prevalence tobacco abstinence rate at 6 month follow-up [primary outcome] and other tobacco abstinence measures); (2) treatment utilization, and (3) cost-effectiveness (cost per quit). Exploratory analyses will examine the intervention's effect on hospital readmissions and mortality in the 6 months after discharge.
