LENEA NE OMOARA !
Un nou studiu (publicat in European Journal of Preventive Cardiology – ianuarie 2019) atesta, din nou, efectele nefaste ale sedentarismului. De data aceasta un grup de autori chinezi (Shanhai) au identificat un risc semnificativ mai mare de deces la pacientii care au facut un infarct si care, anterior evenimentului, erau foarte sedentari (respectiv mai mult de 4 ore zilnic petrecute stand pe scaun sau culcati in pat). Concluzia este simpla!

Sedentary time, metabolic abnormalities, and all-cause mortality after myocardial infarction: A mediation analysis Zhijun Wu, Zhe Huang, Yuntao Wu, Shue Huang, Yanxiu Wang, Haiyan Zhao, Shuohua Chen, Shouling Wu, Xiang Gao Eur J Preventive Cardiology, Volume 26 Issue 1, January 2019 Abstract Background. Sedentary time was associated with myocardial infarction (MI) and metabolic diseases in previous studies.
To investigate whether sedentary time measured before disease onset was associated with all-cause mortality among MI survivors and whether the sedentary time–mortality association was mediated by physical activity status and metabolic phenotypes.
In this prospective …study including 101,510 Chinese adults, we used sedentary time, evaluated at 2006 (baseline), to predict further all-cause mortality among individuals who then developed new onset MI from 2006 to December 2013 (n = 989). The post-MI mortality was ascertained after the first non-fatal MI until December 2014…
During 7 years follow up, 180 deaths occurred among these participants with incident MI. Prolonged sedentary time was associated with a higher risk of mortality among MI survivors. The adjusted hazard ratio (HR) of mortality for sedentary time 4–8 hours/day versus <4 hours/day, was 1.62 (95% confidence interval (CI) 1.14–2.31). A high amount of sedentary time (>4 hours/day) and inactive physical activity had an increased risk of all-cause mortality (HR: 2.74, 95% CI 1.34–5.60), relative to those with sedentary time ≤4 hours/day and moderate/vigorous physical activity. Physical inactivity and metabolic factors mediated a small proportion (≤9.2 % for all) of the total association between sedentary time and post-MI mortality.
High sedentary time was significantly associated with all-cause mortality among MI survivors, independent of physical activity status and metabolic abnormalities.
