Routine Assessment and Promotion of Physical Activity in Healthcare Settings A Scientific Statement from the American Heart Association “Summary: Physical inactivity is one of the major risk factors most prevalent in health, where 8 out of 10 American adults do not meet the guidelines for perform- ing aerobic exercise and muscular conditioning and is associated with the high prevalence of cardi- ovascular disease. Improving and maintaining the recommended levels of physical activity leads to the reduction of metabolic risk factors, improved hemodynamic, functional, body composition and epigenetic for chronic non- communicable diseases. Physical activity also has a significant role, in many cases comparable to or superior to interventions with medications, for the prevention and management of more than 40 conditions, such as diabetes mellitus, cancer, cardiovascular disease, obesity, depression, Alz- heimer’s and arthritis. Although most of the modifiable risk fac- tors of cardiovascular disease included in the American Heart Association’s My Life Check – Life’s Simple 7 are routinely evaluated in clinical practice (glucose and lipid profiles, blood pressure, obesity and smoking), physical activity is not typically evaluated. The purpose of this statement is to provide a comprehensive review of evidence of the feasibility, validity and efficacy of evalua- tion and promotion of physical activity in health environments for adult patients”.

DOI: 10.1161/ CIR.0000000000000559 Mary Kapsokefalou, from the Agricul- tural University of Athens (Human Nutrition), Greece, published a text in the Newsletter of the International Chair for Advanced Studies of Hydra- tion (CIEAH), October 2017 edition, in which she presents the benefits of tea for health. It starts mentioning that beverages with more content of favorable nutrients or bioactive com- pounds or lower energy content are positively associated with the risk of chronic diseases, such as reducing the risk of developing coronary pathology, type 2 diabetes, cancer, while improv- ing bone and dental health. She says that tea has unique properties and if it is not added sugar its caloric content is minimal. To document her conclu- sions, she presents a Cochrane review (Santesso & Manheimer, Global Adv Health With. 2014; 3 (2): 66-67) and discusses several studies. On a meta- analysis (Williamson, Nutr Bull. 2017; 42(3):226-235) the intake is associated with the prevention of type 2 diabe- tes. In another, with 16 studies that included 138523 patients (Guo M et al., Nutr Res. 2017; 42:1-10), the associa- tion was related to the improvement of bone density, and still in another one (Huang et al., Nutrition. 2016; 32:3-8), with 9 studies and 465274 participants, it was verified the preventive effect of green tea over the liver cancer in Asian women. About the mechanisms of action, Kapsokefalou indicates the polyphenols, especially the catequi- nas, that have a relationship with the intestinal microflora and with some cardiovascular biomarkers, indicating the antioxidant state of plasma, vaso- dilation, coagulation or inflammation parameters. She refers a revision study published last year (Saeed et al. Bio- medicine & Pharmacotherapy. 2017; 95:1260-1275), in which the “galato epigalocatequina was associated with antioxidant properties, anti-aging, anti-inflammatory, anticancer, antidi- abetic, hypolipidemias, antivirus, anti- microbial, anti-parasitic and memory improvement”. The tea seems to be too good and “is useful for everything”, but the conclusions should be addressed with high critical caution. But, in the meanwhile, tea is still a good drink for the needed hydration. Basil Ribeiro Revista de Medicina Desportiva informa september 2018 · 27
