Filter by: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.
Participants will complete a phone screen and then one laboratory session. After completing in-person screening assessments, eligible participants will complete additional questionnaires. Participants will then choose an e-liquid flavor to use for the rest of the session. Participants will then sample two e-liquids that vary in nicotine content from little or no nicotine to a moderate level of nicotine, and questionnaires evaluating the subjective effects of each one. Participants will then complete a preference assessment where they choose between the two e-liquids. Participants will be blind to the nicotine contents.
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.
This pilot clinical trial studies how well provider training works in increasing patient tobacco cessation counseling and referrals for patients with cancer undergoing radiation therapy. Health care provider training in motivational interviewing techniques and utilizing tobacco cessation resources may help doctors understand how health care providers can effectively increase their confidence in talking to patients about tobacco cessation counseling.
This one-year pilot study of 30 non-treatment seeking young adult e-cigarette/combustible tobacco product dual users (15 males/15 females) will use smartphone-based ecological momentary assessment (EMA) to gather real-time data of e-cigarette and combustible tobacco product behaviors during a 1-week cigarette/e-cigarette dual use period .(1) Participants will respond to daily random prompts assessing in-the-moment use of e-cigarettes/cigarettes and the subjective factors (ratings of satisfaction and withdrawal) and contextual factors (location, activity, social cues) associated with each episode of use. Participants will also complete daily electronic diaries to document e-cigarette use episodes/day, and satisfaction with the e-cigarette experience during the study.
This pilot study will investigate within-person changes in smoking behavior when current adult smokers are systematically switched from smoking menthol cigarettes to non-menthol cigarettes.
This pilot project examined the feasibility of an multilingual interactive video education intervention "an interactive Mobile Doctor intervention (iMD)" to promote patient-provider discussion on tobacco use for Korean- and Vietnamese-speaking male patients at primary care settings.
