Filter by:Tobacco use is a risk factor for at least 20 types of cancer and remains the leading preventable cause of cancer in Canada. Smoking cessation is an important cancer prevention strategy for the close to 2 million Canadian women who currently smoke. However, findings from controlled trials and real-world clinical settings indicate that women have greater difficulty achieving abstinence following a quit attempt than men. There is some evidence that hormonal levels and fluctuations throughout the menstrual cycle (MC) may contribute to the greater difficulty women experience when trying to quit smoking. In this study, the start of a quit attempt using nicotine replacement therapy (NRT) will be targeted to specific phases of MC. It was hypothesized that starting a quit attempt during the first half of MC (follicular phase) will result in increased quit success compared to starting during the second half of MC (luteal phase) or the usual practice of not targeting quit start date to MC phase.
Tobacco use disorder is a chronic, relapsing health condition that necessitates a chronic care approach. However, traditional smoking cessation treatment programs allocate nearly all their resources only to those smokers who are willing to set a quit date. This is problematic because few smokers are ready to set a quit date at any given time, and a smoker's stated intention to quit can change rapidly. One novel potential treatment strategy is to foster practice quitting (PQ), defined as attempting to not smoke for a few hours or days, without pressure or expectation to permanently quit. Although a growing body of evidence supports the role of practice quitting in fostering permanent quit attempts and cessation, there is a significant knowledge gap regarding which treatment strategies should be used to engage smokers in practice quitting. The proposed study will test the role of PQ counseling vs. Motivational Interviewing (MI) counseling, and NRT sampling (four-week supply of nicotine lozenges and patches) vs. none.
Recent findings regarding why Chinese male smokers are reluctant to quit have offered insight for a possible new solution. Consistent with the Cognitive Dissonance Theory, "smoking rationalization beliefs" are a set of beliefs by smokers to rationalize their smoking behavior and avoid quitting. These beliefs have been well studied by global researchers, and a "smoking rationalization beliefs" scale was recently developed and validated for Chinese male smokers. The six dimensions of these beliefs are: smoking functional beliefs, risk generalization beliefs, social acceptability beliefs, safe smoking beliefs, self-exempting beliefs, and quitting is harmful beliefs. Studies on smoking rationalization in China have primarily been observational. Investigators propose to develop a Community-Centered eHealth Smoking Cessation Intervention (CCeSCI). The trinity of CCeSCI are the triangular unity of "smoking rationalization beliefs" framework, the non-physician community workers, and the eHealth technologies. The latter two were previously proven effective in interventional studies (including three conducted by the PI) but not yet widely used in smoking cessation. With the adoption of smoking rationalization beliefs framework aiming to address the cognitive causes of phycological addition to smoking and supported by the community-based behavioral interventions and the use of eHealth, CCeSCI is designed to overcome previous challenges with the principles of people-centeredness, convenience, and personalization.
The purpose of this research study is to evaluate an electronic visit (e-visit) for smoking cessation. Participants will be randomly assigned to receive either the smoking cessation e-visit or not. The e-visit will look similar to an online questionnaire asking about smoking history, motivation to quit, and preferences for medications for quitting smoking. Participants may receive a prescription for a smoking cessation medication as an outcome of the e-visit, if randomized to the e-visit group, but there is no requirement to take any medication. This study consists of questionnaires and breath samples provided at 4 separate time points throughout the study. Participation in this study will take about 24 weeks.
The purpose of this study is to examine racial differences in smoking behaviors and stress responses between African American and white male smokers.
Randomized, controlled, two-armed, single-blinded, superiority trial with 1:1 allocation ratio Nicotine Replacement Therapy(NRT)
The purpose of this study is to describe the relapse rate and characteristics of expectant fathers who quit smoking during their wives' pregnancy, to explore the influencing factors and triggering mechanisms,and describe their experience.
This study is examining different messages to motivate older smokers to quit smoking. Participants will be current smokers, between the ages of 50-80 years old, who do not have a history of cognitive impairment or dementia. Participants can expect to take part in a one-time 30 minute online survey.
A 12-week study for patients who are being treated for Hepatitis C and would like to quit smoking. During the 12 weeks of Hepatitis C treatment, the research team will have counseling sessions with the participants to discuss challenges related to Hepatitis C and smoking.
The study was a non-randomized controlled trial of 12-months' follow-up with 182 Spanish community pharmacists. Intervention community pharmacists received the CESAR training to improve their smoking cessation services, consisting of an initial interview and follow-up visits to identify obstacles and reinforce behaviours. The control group received the usual care. Data were self-reported and collected in a computerized health registration system. Outcomes were smoking cessation and quality of life (EuroQOL-5D) collected at baseline, 6 months', and 12 months' follow-up. Cost data were collected for the study period and included direct health costs, sick leave, and intervention costs. Smoking cessation was analysed through logistic regression models. Generalized linear models were carried out for quality-adjusted life year costs. Incremental cost-effectiveness ratios (ICERs) and cost-utility ratios (RCUI) were calculated. Sensitivity analyses were performed.
