Menée à partir de deux vagues d'enquêtes réalisées en 2014 et 2015 auprès d'un échantillon de 347 lycéens américains non fumeurs ou ayant fumé par le passé, cette étude évalue l'association entre l'utilisation de la cigarette électronique et le risque de tabagisme

E-cigarette use as a predictor of cigarette smoking : results from a 1-year follow-up of a national sample of 12th grade students

Miech, Richard ; Patrick, Megan E. ; Malley, Patrick M. ; Johnston, Lloyd D.

Objective : To prospectively examine vaping as a predictor of future cigarette smoking among youth with and without previous cigarette smoking experience. A secondary aim is to investigate whether vaping may desensitise youth to the dangers of smoking. Methods : Analysis of prospective longitudinal panel data from the nationally representative Monitoring the Future study. The analysis is based on 347 12th grade students who were part of a randomly selected subsample that completed in-school [...]

Mené aux Etats-Unis auprès de 4 347 personnes en vacances sur des lieux à fort ensoleillement, cet essai évalue, en fonction du lieu de villégiature (bord de mer ou non), l'efficacité d'une intervention consistant à promouvoir, par divers canaux de diffusion, les comportements de santé en matière de protection solaire

Effect of an intervention on observed sun protection by vacationers in a randomized controlled trial at North American resorts

Buller, David B. ; Andersen, Peter A. ; Walkosz, Barbara J. ; Scott, Michael D. ; Beck, Larry ; Cutter, Gary R.

During vacations, many individuals receive high-risk sun exposure that is associated with skin cancer. Vacationers in outdoor recreation venues (pretest n = 4347; posttest n = 3986) at warm-weather destination resorts in North America (n = 41) were enrolled in a pair-matched, group-randomized pretest-posttest controlled quasi-experimental design in 2012–14. Print, audiovisual, and online messages based on Transportation Theory and Diffusion of Innovation Theory and promoting advanced sun [...]

Menée en Suède à partir de questionnaires auprès de 61 420 femmes et 45 280 hommes, cette étude évalue l'effet de la consommation de fruits et de légumes sur l'association entre la consommation d'une grande quantité de lait et le risque de décès par maladie cardiovasculaire, cancer ou autres causes

Milk, Fruit and Vegetable, and Total Antioxidant Intakes in Relation to Mortality Rates : Cohort Studies in Women and Men

Michaelsson, K. ; Wolk, A. ; Melhus, H. ; Byberg, L.

High milk consumption might shorten life span through increased oxidative stress. We aimed to determine whether higher mortality rates with high milk consumption are modified by fruit and vegetable intake or total antioxidant intake (oxygen radical absorbance capacity). We used information from food frequency questionnaires completed by 61,420 women in a Swedish cohort (22,391 deaths from the 1987–1990 baseline onward), 36,714 women from a second survey (1997) of this cohort, and 45,280 Swedish [...]

Menée aux Etats-Unis auprès d'une cohorte de 72 308 femmes et d'une cohorte de 41 808 hommes, cette étude évalue l'association entre la consommation de niacine, une forme de vitamine B3 (durée maximale de suivi : 26 ans), et le risque de carcinome basocellulaire (23 256 cas), de carcinome épidermoïde ( 2 350 cas) ou de mélanome (887 cas)

Niacin intake and risk of skin cancer in US women and men

Park, Sang Min ; Li, Tricia ; Wu, Shaowei ; Li, Wen-Qing ; Weinstock, Martin ; Qureshi, Abrar A. ; Cho, Eunyoung

A recent clinical trial found a protective role of niacinamide, a derivative of niacin, against skin cancer recurrence. However, there is no epidemiologic study to assess the association between niacin intake and risk of skin cancer [basal cell carcinoma (BCC), squamous cell carcinoma (SCC) and melanoma]. We prospectively evaluated whether total, dietary and supplemental niacin intake was associated with skin cancer risk based on 72,308 women in the Nurses' Health Study (1984–2010) and 41,808 [...]

Menée aux Pays-Bas à partir de questionnaires auprès de 2 667 fumeurs ou anciens fumeurs adultes (période de suivi : 2013-2014), cette étude évalue l'association entre la proportion de fumeurs dans leur réseau social (famille, amis, ...) et leur réussite en matière de sevrage tabagique ou leur risque de rechute

The role of smoking in social networks on smoking cessation and relapse among adults : A longitudinal study

Blok, David J. ; De Vlas, Sake J. ; van Empelen, Pepijn ; van Lenthe, Frank J.

Understanding the spread of smoking cessation and relapse within social networks may offer new approaches to further curb the smoking epidemic. Whether smoking behavior among social network members determines smoking cessation and relapse of adults however, is less known. For this study, longitudinal data of 4623 adults participating in the Dutch Longitudinal Internet Studies for the Social sciences (LISS) panel were collected in March 2013 with a follow-up in 2014. Logistic regression was used [...]

Mené auprès de 3 120 fumeurs, cet essai compare, du point de vue du taux d'abstinence tabagique à 6 mois, l'efficacité de deux approches d'aide au sevrage tabagique, l'une reposant sur plusieurs entretiens téléphoniques destinés à accompagner les fumeurs dans leur tentative d'arrêter le tabagisme, l'autre consistant à délivrer du matériel pédagogique et des conseils téléphoniques sur les traitements anti-tabagiques

Telephone care co-ordination for tobacco cessation : randomised trials testing proactive versus reactive models

Sherman, Scott E. ; Krebs, Paul ; York, Laura S. ; Cummins, Sharon E. ; Kuschner, Ware ; Guvenc-Tuncturk, Sebnem ; Zhu, Shu-Hong

Objectives : We conducted two parallel studies evaluating the effectiveness of proactive and reactive engagement approaches to telephone treatment for smoking cessation. Methods : Patients who smoked and were interested in quitting were referred to this study and were eligible if they were current smokers and had an address and a telephone number. The data were collected at 35 Department of Veterans Affairs (VA) sites, part of four VA medical centres in both California and Nevada. In study 1, [...]
