We aimed to estimate the percentage and number of incident cancer cases diagnosed in Texas in 2015 that were attributable to insufficient physical activity, and we examined for differences across racial/ethnic subgroups to reveal important causes of and potential avenues for reductions to cancer health disparities. Methods We calculated population attributable fractions for cancers attributable to insufficient physical activity using prevalence data from the Texas Behavioral Risk Factor Surveillance System and relative risk estimates associated with insufficient physical activity from prior studies. Cancer incidence data were gathered from the Texas Cancer Registry. Results Overall, approximately 2.0% of all new cancers or 2094 excess cancer cases diagnosed in 2015 in Texans aged ≥25 years were attributable to insufficient physical activity, with more cancers in women (3.2%) than in men (0.8%). Of all cancer sites, the highest population attributable fraction for insufficient physical activity was observed for endometrial cancers (21.7% compared with 12.7% for colon cancers, 10.9% for premenopausal breast cancers and 2.0% for postmenopausal breast cancers). Hispanics (2.6%) and non-Hispanic blacks (2.5%) had higher proportions of cancers attributable to insufficient physical activity than non-Hispanic whites (1.8%). Conclusions Public health programmes should stress physical activity as a means of cancer prevention, especially among minority groups, who may have disproportionately higher percentages of cancers attributable to insufficient physical activity.","PeriodicalId":36307,"journal":{"name":"BMJ Nutrition, Prevention and Health","volume":" ","pages":"172-179"},"PeriodicalIF":0.0,"publicationDate":"2020-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1136/bmjnph-2020-000087","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"25316363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In current absence of a curative treatment and an effective, safe vaccine, there is a pressing need to focus on identifying and correcting deficits in immune function in order to reduce risk of severe progress of the disease and to lower the number of infections and fatalities. This paper evaluates the most recent literature on zinc status related to antiviral immunity and its possible role in COVID-19. It is concluded that zinc is a critical factor for antiviral immunity. There is ample evidence suggesting that zinc depletion, also prevalent in high-income nations, compromises immune functions. Notably, major risk groups for COVID-19, the elderly, men more than women, obese individuals and patients with diabetes are all at risk of zinc deficiency. Moreover, various widely used antihypertensive drugs and statin therapy have been reported to negatively influence zinc status. As zinc depletion impairs antiviral immunity, it is hypothesised to increase susceptibility for COVID-19. Therefore, dietary preventive measures and prompt implementation of zinc supplementation for risk groups should be considered. Large-scale studies are urgently needed to investigate the role of micronutrients and antiviral immunity, in particular drug-micronutrient immunity interaction.</p>","PeriodicalId":36307,"journal":{"name":"BMJ Nutrition, Prevention and Health","volume":" ","pages":"111-117"},"PeriodicalIF":0.0,"publicationDate":"2020-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1136/bmjnph-2020-000095","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38640453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
