    “Tobacco Dependence Among Intermittent Smokers”

    • Shiffman, Saul;Ferguson, Stuart G.;Dunbar, Michael S.;Scholl, Sarah M.

    Introduction: Intermittent smokers (ITS) are an increasingly prevalent segment of smokers, yet it is unknown whether or how dependence severity may vary across ITS.Methods: Participants were 217 ITS (70 never daily ITS [NITS], 138 converted ITS [CITS], and 9 unknown), who smoked 4–27 days per month, and 197 daily smokers (DS), recruited for a study on smoking patterns. Participants completed questionnaires on dependence (time to first cigarette after waking, Fagerström Test of Nicotine Dependence [FTND], Nicotine Dependence Syndrome Scale [NDSS], Wisconsin Inventory of Smoking Dependence Motives [WISDM], and Hooked on Nicotine Checklist [HONC]) and recorded each cigarette in real time over 3 weeks using Ecological Momentary Assessment. Logistic regression assessed differences in dependence between groups (DS vs. ITS; CITS vs. NITS), and least squares regression examined associations between dependence and smoking behavior (mean, maximum cigarettes per day; proportion of days ...

    “Bidirectional Influences Between Parents and Children in Smoking Behavior: A Longitudinal Full-Family Model”

    • Schuck, Kathrin;Otten, Roy;Engels, Rutger C. M. E.;Barker, Edward D.;Kleinjan, Marloes

    Background: The present study investigated longitudinal associations and bidirectional influences between family members in smoking behavior using a longitudinal full-family design. Family systems provide a powerful social context in which modeling and imitation take place. In current literature, however, bidirectional associations between parents and children in smoking behavior are seldom considered. Methods : Participants were 426 families, including mothers, fathers, and 2 adolescent children. Associations were assessed over 5 waves with yearly intervals using a cross-lagged model in structural equation modeling.Results: Findings demonstrate that families resemble an interactive system affording smoking contagion across family members. Results suggest that associations between parents and children are bidirectional, that is, parental smoking behavior influences adolescent smoking behavior and adolescent smoking behavior influences parental smoking behavior. There is insufficient ...

    Introduction: Despite the high prevalence of smoking in the former Soviet Union (fSU), particularly among men, there is very little information on nicotine dependence in the region. The study aim was to describe the prevalence of nicotine dependence in 9 countries of the fSU and to examine the psychosocial factors associated with nicotine dependence.Methods: Cross-sectional, nationally representative surveys using multistage random sampling were conducted in 2010 with men and women aged 18 years and over in Armenia, Azerbaijan, Belarus, Georgia, Kazakhstan, Kyrgyzstan, Moldova, Russia, and Ukraine. The main outcome of interest was nicotine dependence using the Fagerström Test for Nicotine Dependence. Multivariate regression analysis was then used to explore the influence of a range of psychosocial factors on higher nicotine dependence.Results: Mean nicotine dependence among men in the region as a whole was 3.96, with high dependence ranging from 17% in Belarus to 40% in Georgia. ...

    “An Internet Survey of Use, Opinions and Preferences for Smoking Cessation Medications: Nicotine, Varenicline, and Bupropion”

    • Etter, Jean-François;Schneider, Nina G.

    Introduction : We assessed use, compliance and preferences among smoking cessation medications in a “real world” sample of current and former smokers. Methods : Internet survey on a smoking cessation website (French/English, 2008–2010) to assess use of nicotine replacement therapies (NRT), varenicline, and bupropion. Results : There were 885 participants (39% current smokers, 61% former smokers), the majority of the sample (70%) was female. The most frequently used medications were, in order: patches (40%), varenicline (23%), nicotine gum (16%), nicotine lozenge/tablet (10%), bupropion (8%), and inhaler (3%). Satisfaction, perceived relief of craving/withdrawal and effectiveness were best for varenicline and lowest for gum. In current users, duration of use was longest for gum (121 days), lozenge/tablet (152 days) and shortest for patch (25 days). Daily use was good for lozenge (9 pieces/day) but less than recommended for gum (6 pieces/day) and inhaler (2 plugs/day). People who ...

    “Determinants of the intention of post-secondary students to eat at least five servings of vegetables and fruit daily”

    • Boucher, D.;Gagné, C.;Côté, F.

    Background Vegetable and fruit consumption helps reduce the occurrence of overweight, obesity, and other chronic diseases. However, only 50% of young adults eat at least five servings of these foods daily. Based on the construct of the Theory of planned behaviour of Ajzen (1991) to which other constructs were added (descriptive norm, perceived regularity of the behaviour and past behaviour), this study aims at identifying the determinants in the intention of young adults in postsecondary education institutions to eat at least five servings of vegetables and fruit daily during the next three months. Methods A sample of 385 students in two CEGEP (junior college institutions) in the Quebec City area participated in this correlation study on a volunteer basis. While attending class, they completed a self-administered questionnaire. Results Hierarchical regression analyses showed that perceived behavioural controls and the perceived weight of facilitating factors and barriers to the ...

    ABSTRACT Propranolol bears antioxidant anti-inflammatory ,anti-angiogenic properties and anti-tumoral effects and therefore is potentially active in the prevention of hepatocellular carcinoma (HCC) .We retrospectively assessed the impact of propranolol treatment on HCC occurrence in a cohort of 291 patients with compensated viral C (HCV) cirrhosis, prospectively screened for HCC. Among them, 93 (50 male, mean age 59.5 ± 12, platelet count:111 ± 53 ) developed esophageal varices (OV) or had OV at inclusion and 198 ( 111 male, mean age 55.8 ± 13, platelet count :137 ± 59) did not. Among patients with OV, 50 received treatment with propranolol. During a median follow-up of 54 months (32, 82), 61 patients developed a HCC. The 3 and 5-year HCC incidence was 4% - 4% and 10%-20% in patients treated and non-treated with propranolol respectively (Gray test p=0.03). In multivariate analysis, propranolol treatment was associated with a low risk of HCC occurrence (HR=0.25 CI 0.09-0.65, ...

    “Aspirin and cancer risk: a quantitative review to 2011”

    • Bosetti, C.;Rosato, V.;Gallus, S.;Cuzick, J.;La Vecchia, C.

    Background: Aspirin has been associated to a reduced risk of colorectal and possibly of a few other common cancers.Methods: To provide an up-to-date quantification of this association, we conducted a meta-analysis of all observational studies on aspirin and 12 selected cancer sites published up to September 2011.Results: Regular aspirin is associated with a statistically significant reduced risk of colorectal cancer [summary relative risk (RR) from random effects models = 0.73, 95% confidence interval (CI) 0.67–0.79], and of other digestive tract cancers (RR = 0.61, 95% CI = 0.50–0.76, for squamous cell esophageal cancer; RR = 0.64, 95% CI = 0.52–0.78, for esophageal and gastric cardia adenocarcinoma; and RR = 0.67, 95% CI = 0.54–0.83, for gastric cancer), with somewhat stronger reductions in risk in case–control than in cohort studies. Modest inverse associations were also observed for breast (RR = 0.90, 95% CI = 0.85–0.95) and prostate cancer (RR = 0.90, 95% CI = ...

    “Preventing Smoking Relapse Using Text Messages: Analysis of Data From the txt2stop Trial”

    • Devries, Karen M.;Kenward, Michael G.;Free, Caroline J.

    Introduction: Interactive text message-based technologies which operate in real time have the potential to be especially effective for delivery of relapse prevention interventions. We examined of a text message system for providing support for lapses and cravings, describe the natural history of requests for support, and predictors of time to requests for support.Methods: Data were collected prospectively from participants in the intervention arm of txt2stop, a large randomized controlled trial of an automated, text message-based smoking cessation intervention. Txt2stop included 2,915 men and women aged 16–78, recruited from London, United Kingdom from 2009 to 2010. Participants could text “crave” or “lapse” when they experienced either; an automated system registered the time of the text message to the nearest second.Results: One thousand one hundred and twenty one (38.5%) participants sent a lapse or crave message to request support. Women were more likely to lapse at ...
