Article Synopsis
  • Smokeless tobacco use is particularly high among rural and medically underserved populations, contributing to serious health issues like cancer and chronic diseases.
  • The study compared the effectiveness of #EnufSnuff.TXT, a text-based intervention, against a modified Enough Snuff program which included an education booklet and motivational texts.
  • Results showed that while #EnufSnuff.TXT was more effective in the short term at three months (29.2% quit rate vs. 19.0%), both methods had similar results by six months (23.1% vs. 20.9%), indicating a need for strategies to enhance long-term cessation success.

While firefighters currently have low smoking rates, rates of smokeless tobacco (SLT) use among this population are remarkably high and substantially greater than similar occupational groups, and the general population. This study explored determinants associated with SLT use, barriers to cessation, and motivators for SLT cessation in the fire service. Key informant interviews were conducted in 23 career firefighters who were current (n = 14) and former (n = 9) SLT users from across the U.

Introduction: The prevalence of smokeless tobacco (SLT) use among firefighters is substantially higher than the general population and similar occupational groups. Despite the significant health risks associated with SLT and its impact on occupational readiness, there are no occupationally-tailored SLT education or treatment programs for the fire service. The purpose of this study was to beta test QUIT SPIT!, a self-help SLT cessation program that is culturally tailored for the US fire service and firefighters who are interested in quitting.

Introduction: Smoking to reduce negative affect has been identified as a key motivational feature of tobacco use. Our recent work suggests that smoking very low nicotine content (VLNC) cigarettes reduces the relationship between negative affect and smoking behavior over a 6-week period. Here, we sought to extend our findings by evaluating whether a gradual or immediate approach to switching to VLNC cigarettes led to a differential reduction in the relationship between affect and smoking behavior over a longer (20-week) period.

Background: Physical therapy (PT) and other exercise-based interventions are core components of care for knee osteoarthritis (OA), but both are underutilized, and some patients have limited access to PT services. This clinical trial is examining a STepped Exercise Program for patients with Knee OsteoArthritis (STEP-KOA). This model of care can help to tailor exercise-based interventions to patient needs and also conserve higher resource services (such as PT) for patients who do not make clinically relevant improvements after receiving less costly interventions.

Introduction: Partner behaviors and attitudes can motivate or undermine a tobacco user's cessation efforts. We developed a multimedia intervention, UCare (Understanding-CAring-REspect) for women who wanted their male partner to quit smokeless tobacco (ST), based on perceived partner responsiveness-the empirically based theory that support is best received when the supporter conveys respect, understanding, and caring.

Methods: One thousand one hundred three women were randomized to receive either immediate access to the UCare website and printed booklet (Intervention; N = 552), or a Delayed Treatment control (N = 551).

Importance: The optimal temporal approach for reducing nicotine to minimally or nonaddictive levels in all cigarettes sold in the United States has not been determined.

Objectives: To determine the effects of immediate vs gradual reduction in nicotine content to very low levels and as compared with usual nicotine level cigarettes on biomarkers of toxicant exposure.

Design, Setting, And Participants: A double-blind, randomized, parallel-design study with 2 weeks of baseline smoking and 20 weeks of intervention was conducted at 10 US sites.

Background: To examine whether number of physical therapy (PT) visits or amount of use of an internet-based exercise training (IBET) program is associated with differential improvement in outcomes for participants with knee osteoarthritis (OA).

Methods: A secondary analysis was performed using data from participants in 2 arms of a randomized control trial for individuals with symptomatic knee OA: PT (N = 135) or IBET (N = 124). We examined associations of number of PT visits attended (up to 8) or number of days the IBET website was accessed during the initial 4-month study period with changes in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) total, pain and function subscales, as well as a 2-min Step Test, at 4-month and 12-month follow-up.

Objectives: We present prevalence estimates of e-cigarette use and conventional cigarette use, and their co-occurrence, among emerging adults across 2 assessments, 11 months apart, conducted in 2013 and 2014. We also report on perceptions of using e-cigarettes and motives for using e-cigarettes and, among e-cigarette users, present data reflecting order of use of conventional tobacco products and e-cigarettes.

Methods: Participants (N = 884) in a longitudinal study, the Oregon Youth Substance Use Project, completed at least one of 2 questionnaires, at average age 22.

Introduction: Although social support is correlated with successful tobacco cessation, interventions designed to optimize social support have shown mixed results. Understanding the process of providing social support for tobacco cessation may suggest new approaches to intervention. Responsiveness theory provides a new framework for classifying supportive behaviors in the context of tobacco cessation.

Introduction: The nicotine metabolite ratio (NMR) of 3'-hydroxycotinine to cotinine is a noninvasive marker of the rate of nicotine metabolism. Fast metabolism (ie, a high NMR) is associated with lower cigarette smoking abstinence rates using transdermal nicotine replacement. We evaluated whether the NMR can be used to predict self-reported nicotine lozenge use and tobacco abstinence among smokeless tobacco users treated for tobacco dependence.

Background: Use of smokeless tobacco (moist snuff and chewing tobacco) is a significant public health problem but smokeless tobacco users have few resources to help them quit. Web programs and telephone-based programs (Quitlines) have been shown to be effective for smoking cessation. We evaluate the effectiveness of a Web program, a Quitline, and the combination of the two for smokeless users recruited via the Web.

Introduction: Relatively few treatment programs have been developed specifically for smokeless tobacco (ST) users who want to quit. Their results suggest that self-help materials, telephone counseling, and nicotine lozenges are efficacious. This study provides the first direct examination of the separate and combined effects of telephone counseling and lozenges.

Background: Although beneficial effects of exercise in the management of knee osteoarthritis (OA) have been established, only 14 -18% of patients with knee OA receive an exercise from their primary care provider. Patients with knee OA cite lack of physician exercise advice as a major reason why they do not exercise to improve their condition. The purpose of this pilot study was to investigate use of a web-based Therapeutic Exercise Resource Center (TERC) as a tool to prescribe strength, flexibility and aerobic exercise as part of knee OA treatment.

The purpose of this study was to test whether an interactive, web-based training program is more effective than an existing, flat-text, e-learning program at improving oral health students' knowledge, motivation, and self-efficacy to address signs of disordered eating behaviors with patients. Eighteen oral health classes of dental and dental hygiene students were randomized to either the Intervention (interactive program; n=259) or Alternative (existing program; n=58) conditions. Hierarchical linear modeling assessed for posttest differences between groups while controlling for baseline measures.

Article Synopsis
  • Oral healthcare providers have a unique opportunity to detect disordered eating behaviors early due to their ability to observe oral and physical signs, but training in this area is limited in existing curricula.
  • A theory-driven, Web-based training program was tested to enhance the skills of oral health students in preventing disordered eating behaviors, using a structured evaluation framework.
  • Results showed significant improvements in students' attitudes, knowledge, and self-efficacy, indicating that Web-based training can effectively prepare oral healthcare providers for secondary prevention of disordered eating issues.

Long-term smokeless tobacco (ST) use is associated with cardiovascular disease and cancer, but not all ST users want to quit. Previous studies have evaluated the effectiveness of nicotine lozenges and tobacco-free snuff for reducing ST use among ST users not ready to quit, but no comparative effectiveness trials of these two products have been conducted. We conducted a multicenter, randomized clinical pilot study evaluating the comparative effectiveness of the 4-mg nicotine lozenge and tobacco-free snuff for reducing ST use and increasing tobacco abstinence among ST users with no intention of quitting in the next 30 days.
