Associations Between E-Cigarette Type, Frequency of Use, and Quitting Smoking: Findings From a Longitudinal Online Panel Survey in Great Britain

Hitchman, Sara C. ; Brose, Leonie S. ; Brown, Jamie ; Robson, Debbie ; McNeill, Ann

Introduction : E-cigarettes can be categorized into two basic types, (1) cigalikes, that are disposable or use pre-filled cartridges and (2) tanks, that can be refilled with liquids. The aims of this study were to examine: (1) predictors of using the two e-cigarette types, and (2) the association between type used, frequency of use (daily vs. non-daily vs. no use), and quitting. Methods : Online longitudinal survey of smokers in Great Britain was first conducted in November 2012. Of 4064 [...]

Menée aux Etats-Unis à partir d'une enquête réalisée en 2012 auprès de 24 658 collégiens ou lycéens, cette étude évalue l'association entre le fait d'avoir reçu des bons de réduction pour acheter des cigarettes et leurs perceptions vis-à-vis du tabagisme ainsi que leur intention de fumer ou d'arrêter le tabagisme

The associations between exposure to tobacco coupons and predictors of smoking behaviours among US youth

Choi, Kelvin

Introduction : A recent report showed that 13.1% of US middle and high school students were exposed to tobacco coupons in the past 30 days in 2012. The current study reanalysed data from the National Youth Tobacco Survey 2012 to examine the associations between exposure to tobacco coupons in the past 30 days and predictors of smoking among US youth, by smoking status. Methods : 24 658 middle and high school students were asked if and where they had received tobacco coupons in the past 30 days. [...]

Menée en Californie à partir d'une enquête auprès de 1 000 fumeurs, cette étude évalue l'effet de l'utilisation de la cigarette électronique sur la consommation de cigarettes et l'arrêt du tabagisme

E-Cigarette Use in the Past and Quitting Behavior in the Future: A Population-Based Study

Al-Delaimy, Wael K. ; Myers, Mark G. ; Leas, Eric C. ; Strong, David R. ; Hofstetter, C. Richard

Objectives : We examined whether smokers who used e-cigarettes are more likely to quit after 1 year than smokers who had never used e-cigarettes. Methods : We surveyed California smokers (n = 1000) at 2 time points 1 year apart. We conducted logistic regression analyses to determine whether history of e-cigarette use at baseline predicted quitting behavior at follow-up, adjusting for demographics and smoking behavior at baseline. We limited analyses to smokers who reported consistent [...]

Menée à partir de questionnaires auprès de 738 patients présentant un ou plusieurs adénomes colorectaux et auprès de 697 témoins, cette étude évalue l'association entre la consommation de café et le risque d'adénome colorectal

Coffee intake and the risk of colorectal adenoma: The colorectal adenoma study in Tokyo

Budhathoki, Sanjeev ; Iwasaki, Motoki ; Yamaji, Taiki ; Sasazuki, Shizuka ; Tsugane, Shoichiro

Coffee is a commonly consumed beverage which contains several potential anticarcinogenic and chemopreventive compounds, and has been hypothesized to have protective effects in colorectal neoplasia. However, the limited available data on coffee consumption in relation to colorectal adenoma (CRA), a precursor lesion to most colorectal cancers, remain largely inconsistent. In this study, we evaluated the association of coffee intake with the risk of CRA in a middle-aged Japanese population. Study [...]

Menée à partir d'échantillons plasmatiques prélevés sur 32 826 participantes puis à nouveau sur 18 743 d'entre elles (durée de suivi : 20 ans), cette étude évalue l'association entre les niveaux de caroténoïdes et le risque de cancer du sein (2 188 cas)

Plasma carotenoids and risk of breast cancer over 20 y of follow-up

Eliassen, A Heather ; Liao, Xiaomei ; Rosner, Bernard ; Tamimi, Rulla M ; Tworoger, Shelley S ; Hankinson, Susan E

Background : Increasing evidence suggests that carotenoids, which are micronutrients in fruit and vegetables, reduce breast cancer risk. Whether carotenoids are important early or late in carcinogenesis is unclear, and limited analyses have been conducted by breast tumor subtypes. Objectives: We sought to examine issues of the timing of carotenoid exposure as well as associations by breast tumor subtypes. Design: We conducted a nested case-control study of plasma carotenoids measured by using [...]

A partir d'une revue systématique de la littérature publiée jusqu'en mai 2014 (15 études incluant au total 5 482 cas et 14 130 témoins ; 1 étude comportant 34 691 femmes ménopausées), cette méta-analyse évalue l'association entre la consommation de caroténoïdes d'origine naturelle et le risque de cancer de la tête et du cou

Carotenoid intakes from natural sources and head and neck cancer: a systematic review and meta-analysis of epidemiological studies

Leoncini, Emanuele ; Nedovic, Darko ; Panic, Nikola ; Pastorino, Roberta ; Edefonti, Valeria ; Boccia, Stefania

Because of their role as antioxidants, the intake of carotenoids has been hypothesized to reduce the risk of head and neck cancer (HNC). We conducted a systematic review and meta-analysis of the epidemiological studies to investigate whether the intake of specific carotenoids from dietary sources, as well as combined carotenoids, is associated with the risk of HNC according to cancer subsites. A comprehensive literature search of Medline and Scopus databases was conducted. Sixteen articles were [...]

Menée à partir de données de registres danois portant sur 5 382 patientes atteintes d'un cancer de l'endomètre diagnostiqué entre 2000 et 2009 et sur 72 127 témoins, cette étude évalue, en fonction de l'obésité, de la parité ou de l'utilisation d'un traitement hormonal substitutif, l'association entre l'utilisation d'anti-inflammatoires non stéroïdiens et le risque de cancer de l'endomètre

Use of nonsteroidal anti-inflammatory drugs and risk of endometrial cancer : a nationwide case–control study

Brøns, Nanna ; Baandrup, Louise ; Dehlendorff, Christian ; Kjaer, SusanneK

Purpose : We examined the association between use of low-dose aspirin and non-aspirin nonsteroidal anti-inflammatory drugs (NSAIDs) and endometrial cancer risk in a nationwide case–control study. Methods : Cases were all women in Denmark diagnosed with endometrial cancer during 2000–2009. Age-matched female controls were randomly selected by risk-set sampling. Information on NSAID use was collected from the Prescription Registry and classified according to duration and intensity. Conditional [...]

Menée à partir des données d'une enquête canadienne réalisée entre 2005 et 2012 auprès de 89 743 participants, cette étude évalue l'intérêt d'une politique anti-tabac interdisant de fumer sur les terrasses des restaurants et des bars pour réduire l'exposition des fumeurs et non fumeurs au tabagisme passif

Effect of smoke-free patio policy of restaurants and bars on exposure to second-hand smoke

Azagba, Sunday

Objective : While there is increasing support for restricting smoking in restaurants and bars patios, there is limited evidence on the effectiveness of this policy. This study examined the effect of smoke-free patio policy of restaurants and bars on adult second-hand smoke (SHS) exposure. Methods : Data were drawn from the 2005-2012 Canadian Tobacco Use Monitoring Survey (n=89,743), a repeated cross-sectional survey of youth and adult. Regression analysis, a quasi-experimental design was used [...]

Menée auprès de 316 participantes présentant un risque élevé de développer un cancer du sein, cette étude évalue, en fonction de l'origine ethnique et de catégories de risque (présence d'une mutation du gène BRCA, antécédents de carcinome canalaire ou lobulaire in situ), la proportion de participantes utilisant des anti-estrogènes dans le cadre d'une chimioprévention

Breast Cancer Chemoprevention among High-risk Women and those with Ductal Carcinoma In Situ

Reimers, Laura L. ; Sivasubramanian, Parijatham S. ; Hershman, Dawn ; Terry, Mary Beth ; Greenlee, Heather ; Campbell, Julie ; Kalinsky, Kevin ; Maurer, Matthew ; Jayasena, Ramona ; Sandoval, Rossy ; Alvarez, Maria ; Crew, Katherine D.

Chemoprevention with the anti-estrogens, tamoxifen, raloxifene, and aromatase inhibitors, reduce breast cancer incidence in high-risk women; however, uptake has been poor (<5%) in the prevention setting. We assessed use of anti-estrogens for breast cancer prevention, among high-risk women seen at an academic breast center, to observe how uptake rates compare in this setting. We collected data on demographics, breast cancer risk factors, and health behaviors via self-administered questionnaires [...]
