Purpose: Physical activity (PA) has been suggested to reduce the risk of cancer. However, previous studies have been inconsistent regarding the relationship between PA and the risk of developing gastric cancer (GC). The purpose of this study was to evaluate the impact of PA on the incidence and mortality risk of GC through a meta-analysis, as well as investigate potential dose-response relationships. Methods: A systematic literature search was conducted in 10 electronic databases and 4 [...]

Menée à partir des données d'une étude multicentrique italienne portant sur 4 154 témoins et 1 953 patients atteints d'un cancer du côlon ou du rectum, cette étude analyse l'association entre l'apport alimentaire total en choline et le risque de développer la maladie

Introduction: Phospholipids are possible favorable agents for colorectal cancer (CRC). Choline has been inversely related to CRC risk but findings are inconsistent. We assessed the effect of dietary sphingomyelin (SM) choline moiety and total choline intake on risk of CRC. Method: This analysis is based on a multicenter case–control study conducted between 1992 and 1996 in Italy. A total of 6107 subjects were enrolled, including 1225 colon cancer cases, 728 rectal cancer cases and 4154 [...]

Objective: To use a standardised e-cigarette tax measure to examine the impact of e-cigarette taxes on the price and sales of e-cigarettes and cigarettes in the USA. Design: We used State Line versions of NielsenIQ Retail Scanner data from quarter 4 of 2014 through quarter 4 of 2019 to calculate e-cigarette and cigarette prices and sales in 23 US states. We then estimated how these outcomes are associated with standardised state-level e-cigarette taxes, controlling for state fixed effects, [...]

Kelly, Brian C. ; Vuolo, Mike ; Orsini, Maria M. ; Maggs, Jennifer L. ; Staff, Jeremy

Introduction: While tobacco use has declined among youth, electronic nicotine delivery systems (ENDS) have the potential to disrupt or reverse these trends. Policies for tobacco and ENDS may have an impact on adolescent ENDS use. The effects of state-level policies were examined for both tobacco and ENDS indoor use bans, excise taxes, and age of purchase laws on past month adolescent ENDS use from 2013 to 2019. Methods: The study uses cohort data from the Population Assessment of Tobacco and [...]

Effect of Postal-Mailed Nicotine Patches on Tobacco Cessation Among Smokers in Rural Canada: A Randomized Clinical Trial

Cunningham, John A. ; Chaiton, Michael ; Leatherdale, Scott T. ; Godinho, Alexandra ; Schell, Christina

Nicotine replacement therapy (NRT) has been found to promote tobacco cessation in multiple trials.1,2 A secondary analysis3 of a trial4 examining the efficacy of mailed nicotine patches with tobacco cessation indicated that the intervention might have a larger impact in rural regions than in urban areas (odds ratio [OR], 9.59 vs 2.16). The current randomized clinical trial recruited participants from rural regions with the hypothesis that those receiving the NRT package would display [...]

Background: The standardized scoring system assessing adherence to the 2018 World Cancer Research Fund (WCRF)/American Institute for Cancer Research (AICR) cancer prevention recommendations assigns equal weight for each recommendation, thereby giving higher weight to dietary factors collectively (5 points) than adiposity (1 point) and physical activity (1 point). An alternative score assigning equal weights to the adiposity, physical activity, alcohol, and other dietary (composite) [...]
