Exercise-related public health recommendations and research for increased fitness and health had long focused on vigorous exercise or the lack thereof. Recently scientific interest in possible effects of sedentary behaviour (SB) (sitting) independent of moderate-vigorous intensity exercise has been growing.We conducted a selective literature search in Pubmed and the Sedentary Research Database with the outcomes SB, risk factors, mortality and morbidity in adults. We included only reviews and systematic reviews.Observational studies suggest an association between SB and all-cause and cardiovascular, but not cancer mortality. SB also seems to be associated with diabetes and overweight/weight gain. Evidence for other diseases, such as cardiovascular diseases, hypertension, cancer, and mental diseases is limited also because of the heterogeneity and poor methodology of the -studies. Intervention studies found inconsistent evidence that SB is associated with detrimental effects on markers of cardiometabolic risk.The evidence on the detrimental effects of sedentary behaviour is decreasingly convincing with the endpoints of mortality, -morbidity, and markers of metabolic risk, in that order. Higher TV and screen time, but not total SB seems to be associated with higher all-cause and cardiovascular, but not cancer mortality. Further intervention studies are needed to establish -dose-response relationships and potentially protective effects of cardiorespiratory fitness and physical activity.
与运动相关的公共卫生建议以及关于增强体质和健康的研究长期以来一直聚焦于剧烈运动或缺乏剧烈运动的情况。最近，对于久坐行为（SB）（坐着）独立于中等强度至剧烈强度运动可能产生的影响，科学界的兴趣日益浓厚。我们在PubMed和久坐研究数据库中进行了选择性文献检索，检索结果涉及成年人的久坐行为、风险因素、死亡率和发病率。我们仅纳入了综述和系统综述。观察性研究表明，久坐行为与全因死亡率和心血管疾病死亡率相关，但与癌症死亡率无关。久坐行为似乎还与糖尿病以及超重/体重增加有关。对于其他疾病，如心血管疾病、高血压、癌症和精神疾病，证据也有限，这也是由于研究的异质性和方法欠佳所致。干预性研究发现，关于久坐行为与对心血管代谢风险标志物产生有害影响之间的关联，证据并不一致。关于久坐行为有害影响的证据，在死亡率、发病率和代谢风险标志物这些终点方面，其说服力依次递减。较高的看电视和看屏幕时间，而非总的久坐行为，似乎与较高的全因死亡率和心血管疾病死亡率相关，但与癌症死亡率无关。需要进一步开展干预性研究，以确定剂量反应关系以及心肺适能和身体活动的潜在保护作用。
