In contemporary society, prolonged sitting has been engineered into our lives across many settings, including transportation, the workplace, and the home. There is new evidence that too much sitting (also known as sedentary behavior - which involves very low energy expenditure, such as television viewing and desk-bound work) is adversely associated with health outcomes, including cardio-metabolic risk biomarkers, type 2 diabetes and premature mortality. Importantly, these detrimental associations remain even after accounting for time spent in leisure time physical activity. We describe recent evidence from epidemiological and experimental studies that makes a persuasive case that too much sitting should now be considered an important stand-alone component of the physical activity and health equation, particularly in relation to diabetes and cardiovascular risk. We highlight directions for further research and consider some of the practical implications of focusing on too much sitting as a modifiable health risk.
在当代社会，长时间坐着已经成为我们生活中的常态，无论是在交通、工作场所还是家庭中。有新的证据表明，长时间坐着（也称为久坐行为，即涉及极低能量消耗的行为，如看电视和伏案工作）与健康结果呈负相关，包括心血管代谢风险生物标志物、2 型糖尿病和过早死亡。重要的是，即使考虑到休闲时间体力活动的时间，这些不利的关联仍然存在。我们描述了来自流行病学和实验研究的最新证据，这些证据有力地表明，现在应该将长时间坐着视为体力活动和健康等式中的一个重要独立组成部分，特别是与糖尿病和心血管风险有关。我们强调了进一步研究的方向，并考虑了将长时间坐着作为可改变的健康风险来关注的一些实际影响。
