Filter by:The 2-year research plan will test the Put It Out Project (POP) in a pilot randomized trial (N=120) compared to TSP and two historical control conditions. Participants will be young adults who smoke, identify as sexual or gender minorities, and use Facebook. The primary outcome will be biochemically verified 7-day abstinence from smoking at 3 and 6 months. Secondary outcomes will be a quit attempt (y/n), stage of change, and thoughts about tobacco abstinence at 3 and 6 mos.
The current study aimed to test a culturally tailored program designed to help Pacific Islanders (PIs) between the ages of 18 and 30 quit smoking cigarettes by using a randomized controlled trial design with one intervention group and one control group.
The study aims to (1) evaluate the effectiveness of the recent renewal of tobacco health warnings (HWs) on noticing and anti-smoking responses, and (2) assess the effect of exposure to point-of-sale (POS) tobacco displays and smoking hotspots on nicotine-craving intensity and smoking-related behaviors. The study will use time-based system-triggered ecological momentary assessments to collect real-time data about exposures to smoking-related cues and behaviors. With a smartphone app installed in the mobile phones of the participants, they will each day complete at least 3 pairs of EMA prompted randomly for only 2 days (a working and a nonworking day). Outcomes include exposure and responses to tobacco HWs, exposure to POS tobacco displays, exposure to smoking hotspots and smoking and quitting outcomes.
Nicotine mediates smoking's addictive effects in the brain. The ratio of 3-hydroxycotinine to cotinine, known as the nicotine metabolite ratio, or NMR, is a genetically- informed biomarker reflecting hepatic CYP2A6 activity and the rate of nicotine metabolism. In light of a recent randomized controlled trial (RCT) in humans in Lancet Respiratory Medicine, which found that the NMR can be used to individualize treatment for smokers, our pilot study aims to determine the feasibility of using NMR to guide selection of pharmacotherapy in clinical populations of daily smokers.
The purpose of this study is to compare intensive telephone counseling (ITC) plus the nicotine patch vs. standard telephone counseling plus the nicotine patch (Usual Care; UC) among current smokers undergoing lung cancer screening. Smoking-related outcomes will be examined at three, six and twelve months post-randomization.
While the military has taken steps to reduce tobacco use over the past two decades, over a quarter of new military recruits report regular tobacco use prior to enlistment. This rate is higher than the national prevalence of 21.3% of US adults. Brief health prevention programs may be particularly effective for Airmen in Technical Training, given that all Airmen have been tobacco free for 11 ½ weeks and nearly 2/3rds are confident that they won't return to tobacco. We have developed and validated a Brief Tobacco Intervention (BTI) that is currently being implemented as part of Technical Training. We found that a motivational interviewing based, 40 minute BTI was efficacious in increasing perceived harm and decreasing intentions to use tobacco in a sample of 1055 Air Force trainees. Although we obtained significant positive changes in latent cognitive constructs for tobacco behavior that are highly predictive of future tobacco use in youth and young adults, the Little et al study did not obtain measures of actual tobacco resumption following the ban on tobacco in Air Force training. Given that 69.8% of all tobacco resumption/initiation occurs in Technical Training, a study that evaluates the short-term impact of our BTI on actual tobacco use is necessary prior to conducting the full scale R01 that would evaluate the long term efficacy of the BTI intervention. Thus, we propose the following Specific Aims: (1) To recruit approximately 2,000 Air Force trainees at the beginning of Technical Training at Joint Base San Antonio-Lackland Air Force in San Antonio, Texas during the 11 ½ week involuntary cessation ban; (2) To randomize participants to either (a) receive our cigarette smoking military tailored pamphlet (HL095758), The Airmen's Guide to Remaining Tobacco Free (Airmen's Guide; which has been disseminated and is now the standard of care in the Air Force) or (b) the Airmen's Guide + Brief Tobacco Intervention (BTI); (3) To determine the short-term (3 month, end of Technical Training) efficacy of the intervention on tobacco abstinence. Our primary outcome is tobacco abstinence at the end of Technical Training to determine an estimated effect size as well as establish the requisite preliminary work for a subsequent R01. Given that over 220,000 new recruits enter the military annually in one of the service branches, the public health implications of an effective brief tobacco intervention targeting the most commonly used tobacco for military personnel in Technical Training is considerable. If the BTI is proven efficacious it can be easily disseminated to other service branches that have similar tobacco bans during Technical Training.
Using a 2x2 randomized factorial design, we will conduct a statewide field trial in Missouri to compare the relative and combined effects of these two strategies for augmenting an existing, evidence-based tobacco quitline program. Among 2000 low-income smokers, half will receive standard Missouri quitline services and half will receive new Specialized Quitline services targeted to this group. In each of these groups, half also will receive calls from a trained navigator to help them address unmet Basic Needs and the accompanying psychological distress that act as barriers to smoking cessation.
This study will evaluate exposure to tobacco constituents from two moist snuff products, and provide a basis for comparing mouth-level exposure (MLE) in moist snuff users after use of each of the two moist snuff products.

This is a European study which is part of a larger research project (The TackSHS project) funded by the European Union's Horizon 2020 Research and Innovation Programme (Grant Agreement No 681040) and led by the Catalan Institute of Oncology. This study will examine the efficacy of using personalised air quality measurements in homes of smokers to encourage behaviour-change towards having a smoke-free home environment. Building on recent quantitative and qualitative work showing that feedback of second-hand smoke (SHS) measurement information can help motivate smokers to change their behaviour. This study will develop a targeted intervention for use with socio-economically deprived smokers in four countries (Scotland, Spain, Greece, Italy) across the EU. Two-hundred smokers (50 in each country) will be recruited and offered low-cost, simple to operate particle counting instruments to measure and log SHS levels in their home for a period of 30 days. During this time near real-time, personalised feedback will be provided to, and discussed with, the smoker along with target-setting and exploration of suitable methods of behaviour-change. Feedback will be given via text message to mobile phones, emails and personal voice calls. A final visit will gather data on changes made while a proportion of participants (10-20%) in each country will take part in a further qualitative interview by phone to gather data on their experience of the intervention. Study outcomes will include quantitative measures such as changes in average and maximum fine particulate matter (PM2.5) concentrations and self-declared household smoking rules, while qualitative data will be gathered using questionnaire and interview to explore what elements of the intervention were useful/unhelpful, particularly well/poorly understood, and what were the barriers for those who did not make changes. This WP will provide a comprehensive database of baseline measurements of SHS concentrations in home settings from across the EU with the potential to generate over 8 million minutes of measurements of household air quality. Analysis of the differences by country and possible determinants of exposure will be carried out.
