Menée en Australie par enquêtes réalisées entre 1992 et 2019 auprès de 44 979 adolescents et adultes, cette étude analyse les comportements de protection solaire lors d'activités de loisir dans des lieux publics en plein air (piscines, plages, parcs et jardins)

Sun-protective clothing and shade use in public outdoor leisure settings from 1992 – 2019: Results from cross-sectional observational surveys in Melbourne, Australia

Haynes, Ashleigh ; Nathan, Andrea ; Dixon, Helen ; Wakefield, Melanie ; Dobbinson, Suzanne

Skin cancer presents a significant public health burden in Australia. The present study aimed to supplement population-based estimates of sun protection behaviour by examining setting-specific trends in directly observed sun protection in public outdoor leisure settings. Repeated cross-sectional observational surveys of adolescents and adults were conducted on summer weekends between 11am and 3pm from 1992-2002, 2006-2012, and 2018-2019 (N = 44,979) at pools/beaches and parks/gardens within [...]

Menée aux Etats-Unis à l'aide de données 2014 portant sur 1 504 adolescents et leurs parents, cette étude analyse les facteurs associés à la pratique d'une activité physique

Correlates of Physical Activity, Psychosocial Factors, and Home Environment Exposure among U.S. Adolescents: Insights for Cancer Risk Reduction from the FLASHE Study

Xu, Lei ; Rogers, Charles R. ; Halliday, Tanya M. ; Wu, Qiang ; Wilmouth, Logan

Background and aims: Physical activity (PA) can bring numerous health benefits to adolescents and can largely aid in reducing the various types of cancer risks in their lifespans. However, few adolescents meet the physical activity guidelines recommended by the National Cancer Institute in the United States. Our study aimed to examine the multilevel determinants potentially influencing adolescent’s PA participation. Methods: A secondary analysis of physical activity, home and school [...]

A partir d'une revue systématique de la littérature publiée jusqu'en décembre 2019 (9 études, 13 766 individus), cette méta-analyse évalue le rôle d'une consommation de ginseng dans la prévention du cancer du foie et lors d'un traitement par chimiothérapie

Ginseng Consumption Possible Effect on Liver Cancer: A Meta-Analysis

Zhu, Chenhong ; Wang, Jingyi ; Liu, Weinan ; Chen, Lei ; Abdelrahim, Mohamed E. A. ; Ren, Liping

Introduction: Ginseng is associated to the reduction of the risk of liver-cancer and some time is used as adjuvant therapy to treat liver-cancer, but its outcome remains uncertain. Hence, the present study aimed to determine the association between Ginseng consumption and liver-cancer. Methods: By a systematic-literature search up to Decamber-2019, 9-studies included 13,766 subjects, 9235 Ginseng consumer. Odds ratio (OR) with 95% confidence intervals (CIs) was determined comparing Ginseng [...]

Cet article fait le point sur le rôle de la vitamine D3 dans la prévention, l'incidence et la mortalité des cancers

Role of vitamin D3 in selected malignant neoplasms

Markowska, Anna ; Antoszczak, Michał ; Kojs, Zbigniew ; Bednarek, Wiesława ; Markowska, Janina ; Huczyński, Adam

Vitamin D3 is a fat-soluble essential nutrient affecting multiple biological functions in the organism through calcitriol and the vitamin D3 receptor (VDR). This review article is focused on results of the studies on the relationship between the level of vitamin D3 and cancer incidence or mortality, but also on the anticancer properties of vitamin D3 that support its significant role in the prevention, clinical course and overall survival rates of selected cancers (colorectal, prostate, breast, [...]

Menée en Chine par questionnaire et à l'aide d'échantillons sanguins collectés auprès de 498 témoins et 493 patients atteints d'un cancer colorectal (âge moyen : 57,7 ans), cette étude analyse l'association entre un apport alimentaire de zinc et de sélénium, seuls ou combinés, des polymorphismes des gènes liés au stress oxydant et le risque de développer la maladie

Association between Dietary Zinc and Selenium Intake, Oxidative Stress-Related Gene Polymorphism, and Colorectal Cancer Risk in Chinese Population - A Case-Control Study

Luo, Hong ; Fang, Yu-Jing ; Zhang, Xin ; Feng, Xiao-Li ; Zhang, Nai-Qi ; Abulimiti, Alinuer ; Huang, Chu-Yi ; Zhang, Cai-xia

Zinc and selenium may protect against colorectal cancer (CRC) progression through their anti-oxidative effects. This study examined the independent and combined effect of dietary zinc and selenium intake, and polymorphisms of the oxidative stress-related genes (superoxide dismutase 1, superoxide dismutase 2, glutathione peroxidase, and catalase) on CRC risk in a Chinese case-control study. A total of 493 cases and 498 sex and age-matched controls were randomly selected from an ongoing [...]

A partir d'une revue de la littérature publiée jusqu'en mai 2020 (14 études), cette méta-analyse évalue l'association entre la quantité de fruits et légumes consommés et le risque de cancer des voies biliaires

Vegetable, Fruit Consumption and Risk of Biliary Cancer: Evidence from a Meta-Analysis

Huai, Jiaping ; Ye, Xiaohua

Background and objective: This meta-analysis was performed to assess the association between vegetable and fruit (VF) consumption and biliary cancer risk. Method: Relevant studies were identified by a search of MEDLINE and Embase databases. The summary relative risks (RRs) with 95% confidence intervals (CIs) for the highest vs. lowest consumption and dose-response analyses were assessed. Results: Fourteen studies were eligible. The summary RRs associated with the risk of biliary cancer for the [...]

Menée aux Etats-Unis entre 2016 et 2019 dans 264 structures locales de santé, cette étude analyse l'effet d'une intervention (webinaires didactiques sur le HPV, stratégie de communication auprès des adolescents...) pour améliorer le taux de vaccination contre le papillomavirus humain

A quality improvement collaborative to increase human papillomavirus vaccination rates in local health department clinics

Wallace-Brodeur, Rachel ; Li, Rui ; Davis, Wendy ; Humiston, Sharon ; Albertin, Christina ; Szilagyi, Peter G. ; Rand, Cynthia M.

Human papillomavirus (HPV) vaccination rates are well below the Healthy People 2020 goal of 80%. Vaccinating in settings other than primary care, such as local health departments (LHDs), may help achieve higher HPV immunization rates. We tested the effect of a quality improvement (QI) collaborative to reduce missed opportunities (MOs) for HPV vaccine in LHDs. Between 2016 and 2019, we conducted four consecutive cohorts of a virtual QI collaborative at 24 LHDs across multiple states. [...]
