Irvine, Dylan S ; McGarity-Shipley, Ellen ; Lee, Eun-Young ; Janssen, Ian ; Leatherdale, Scott T

This study examined longitudinal associations between e-cigarette use, cigarette smoking, physical activity, and recreational screen time (ST) in a cohort of Canadian adolescents (ages 14-17 years; grades 9-12).Data from 5,951 adolescents who participated in COMPASS Year 4 (2015–16; baseline) and Year 6 (2017–18; follow-up) were used. Exposures included e-cigarette use and cigarette smoking. Outcomes included cut-points for moderate- to vigorous- physical activity (MVPA; ≥ 60 min/d), muscular [...]

Background: Little prospective evidence exists about whether a combination of healthy lifestyle factors is related to a considerable reduction of liver cancer risk. Methods: Based on the prospective China Kadoorie Biobank (CKB) cohort with a total of 492,640 Chinese adults, we examined the associations of five lifestyle factors with risk of liver cancer. Low-risk lifestyle factors were defined as non-smoking, non-drinking, median or higher level of physical activity, a healthy diet, and [...]

A partir d'une revue systématique de la littérature (11 études), cette méta-analyse évalue l'association entre une consommation de fibres alimentaires solubles ou insolubles et le risque de cancer colorectal

Soluble and Insoluble Dietary Fiber Consumption and Colorectal Cancer Risk: A Systematic Review and Meta-Analysis

Arayici, Mehmet Emin ; Mert-Ozupek, Nazli ; Yalcin, Femin ; Basbinar, Yasemin ; Ellidokuz, Hulya

Colorectal cancer (CRC) is the third most common cancer worldwide with a high mortality rate. Dietary fibers, both soluble and insoluble, are essential for reducing the risk of CRC. In this study, a meta-analysis was performed to examine the relationship between the soluble and insoluble dietary fiber consumption and CRC risk. The highest vs. lowest fiber concentrations were compared by using PRISMA guidelines. To determine publishing bias, the Egger test; assess study heterogeneity I2 [...]

Menée en Australie à partir de données portant sur 367 058 personnes (durée de suivi : jusqu'à 22 ans), cette étude évalue la part des cancers de la thyroïde attribuable au surpoids ou à l'obésité, en fonction du sexe notamment

Thyroid cancers potentially preventable by reducing overweight and obesity in Australia: a pooled cohort study

Laaksonen, Maarit A. ; MacInnis, Robert J. ; Canfell, Karen ; Shaw, Jonathan E. ; Magliano, Dianna J. ; Banks, Emily ; Giles, Graham G. ; Byles, Julie E. ; Gill, Tiffany K. ; Mitchell, Paul ; Hirani, Vasant ; Cumming, Robert G. ; Vajdic, Claire M.

Thyroid cancer incidence and the prevalence of overweight and obesity are increasing, but the future thyroid cancer burden attributable to contemporary levels of overweight and obesity has not been evaluated before. We quantified this burden in Australia, and assessed whether the overweight/obesity-attributable burden differed by sex or other population subgroupings. We estimated the strength of the associations of overweight and obesity with thyroid cancer with adjusted proportional hazards [...]

Menée en Malaisie par questionnaire auprès de 384 étudiantes vaccinées contre le papillomavirus humain (HPV), cette étude analyse leur perception et leur connaissance des moyens de prévention du HPV et du cancer du col de l'utérus

Perception and knowledge of human papillomavirus (HPV) vaccine for cervical cancer prevention among fully vaccinated female university students in the era of HPV vaccination: a cross-sectional study

Chew, Kah Teik ; Kampan, Nirmala ; Shafiee, Mohamad Nasir

Objective: To assess the perception and knowledge of cervical cancer prevention among fully vaccinated female university students in the era of human papillomavirus (HPV) vaccination. Design: Cross-sectional using a validated questionnaire. Setting: Face-to-face interview at a public university in Malaysia. Participants: 384 fully vaccinated female students were included in the study. Results: The total knowledge score in the questionnaire was 18 and was ranked according to score level into [...]

Menée à partir de données des registres américains des cancers, cette étude analyse l'association entre la mise en oeuvre de la vaccination contre le papillomavirus humain et l'évolution de l'incidence du cancer du col de l'utérus et de la mortalité spécifique sur la période 2001-2017

Human Papillomavirus Vaccination and Trends in Cervical Cancer Incidence and Mortality in the US

Tabibi, Tara ; Barnes, Justin M. ; Shah, Aneri ; Osazuwa-Peters, Nosayaba ; Johnson, Kimberly J. ; Brown, Derek S.

Human papillomavirus (HPV) is a common sexually transmitted infection and is implicated in most cervical cancer cases. Vaccination against HPV for women and girls aged 11 to 26 years was first recommended in 2006. Randomized clinical trials showed vaccine-driven decreases in precancerous lesions, and observational studies showed vaccine-associated decreases in cervical cancer incidence. However, data demonstrating vaccine-associated changes in cervical cancer mortality are lacking. We aimed to [...]

Cette étude identifie les facteurs empêchant de réduire la part des cancers attribuable à la consommation de boissons alcoolisées

Alcohol and Cancer: Existing Knowledge and Evidence Gaps across the Cancer Continuum

Gapstur, Susan M. ; Bandera, Elisa V. ; Jernigan, David H. ; LoConte, Noelle K. ; Southwell, Brian G. ; Vasiliou, Vasilis ; Brewster, Abenaa M. ; Naimi, Timothy S. ; Scherr, Courtney L. ; Shield, Kevin D.

Alcoholic beverages are carcinogenic to humans. Globally, an estimated 4.1% of new cancer cases in 2020 were attributable to alcoholic beverages. However, the full cancer burden due to alcohol is uncertain because for many cancer (sub)types, associations remain inconclusive. Additionally, associations of consumption with therapeutic response, disease progression, and long-term cancer outcomes are not fully understood, public awareness of the alcohol–cancer link is low, and the [...]
