Menée à partir de données portant sur 22 000 femmes (âge moyen : 73,4 ans ; durée moyenne de suivi : 7,9 ans), cette étude analyse l'association entre le nombre de pas par jour, la cadence de la marche et le risque de cancer par localisation

Objective: Accumulating more steps/day is associated with a lower risk of cancer mortality and composite cancer outcomes. However, less is known about the relationship of steps/day with the risk of multiple site-specific cancers. Methods: This study included >22,000 women from the Women's Health Accelerometry Collaboration Cohort (2011−2022), comprised of women from the Women's Health Study and Women's Health Initiative Objective Physical Activity and Cardiovascular Health Study. Steps/day and [...]

Menée aux Etats-Unis à partir de données portant sur 5 520 personnes, cette étude analyse l'association entre la consommation de vitamines A, C, D et E et le risque de leucémie

Qin, Rui ; Xiang, Jinping ; Zou, Luping ; Xiang, Guoqiang ; Xiang, Hang

The present study assessed potential associations between vitamin intake and leukemia in a national sample of adults in the United States. A total of 5520 participants were included in this cross-sectional study to investigate the relationship between vitamin intake (including vitamins A, C, D, and E) and leukemia. Results revealed negative associations between vitamin C and E intake and leukemia, whereas associations between vitamin A and D and leukemia were not statistically significant. For [...]

Menée à l'aide d'une modélisation mathématique intégrant des données de 100 pays à faible ou moyen revenu, cette étude estime, pour la période 2020-2030, l'impact de 9 stratégies de vaccination contre le papillomavirus humain sur l'incidence du cancer du col de l'utérus et le risque de décès, en fonction des contraintes d'approvisionnement en vaccins

Optimal human papillomavirus vaccination strategies in the context of vaccine supply constraints in 100 countries

Prem, Kiesha ; Cernuschi, Tania ; Malvolti, Stefano ; Brisson, Marc ; Jit, Mark

Background: Countries are recommended to immunise adolescent girls routinely with one or two doses of human papillomavirus (HPV) vaccines to eliminate cervical cancer as a public health problem. With most existing vaccine doses absorbed by countries (mostly high-income) with existing HPV vaccination programmes, limited supply has been left for new country introductions until 2022; many of those, low- and middle-income countries with higher mortality. Several vaccination strategies were [...]

Menée à l'aide de données canadiennes portant sur 838 hommes ayant des relations homosexuelles (âge : 16-30 ans), cette étude analyse la prévalence d'infections orales liées au papillomavirus humain (HPV) en fonction du statut vaccinal anti-HPV

Oral human papillomavirus (HPV) infections are a leading cause of oropharyngeal cancers. In 2015 and 2016, HPV vaccines became publicly funded for gay, bisexual, and other men who have sex with men (GBM) under 27 years of age in most Canadian provinces.Between 2017 and 2019, sexually-active GBM in Montreal, Toronto, and Vancouver were recruited through respondent-driven sampling. Participants aged 16 to 30 years were invited to self-collect oral rinse specimens for HPV testing. We estimated HPV [...]
