Sedentary behavior is an emerging risk factor for cardiovascular disease (CVD) and may be particularly relevant to the cardiovascular health of older adults. This scoping review describes the existing literature examining the prevalence of sedentary time in older adults with CVD and the association of sedentary behavior with cardiovascular risk in older adults. We found that older adults with CVD spend >75 % of their waking day sedentary, and that sedentary time is higher among older adults with CVD than among older adults without CVD. High sedentary behavior is consistently associated with worse cardiac lipid profiles and increased cardiac risk scores in older adults; the associations of sedentary behavior with blood pressure, CVD incidence, and CVD-related mortality among older adults are less clear. Future research with larger sample sizes using validated methods to measure sedentary behavior are needed to clarify the association between sedentary behavior and cardiovascular outcomes in older adults.
久坐行为是心血管疾病（CVD）的一个新出现的风险因素，可能与老年人的心血管健康特别相关。本综述描述了现有文献，这些文献研究了患有心血管疾病的老年人久坐时间的患病率，以及久坐行为与老年人心血管风险的关联。我们发现，患有心血管疾病的老年人在清醒时间里有超过75%处于久坐状态，而且患有心血管疾病的老年人的久坐时间比没有心血管疾病的老年人更高。在老年人中，高久坐行为一直与较差的心脏脂质谱和增加的心脏风险评分相关；久坐行为与老年人血压、心血管疾病发病率和心血管疾病相关死亡率之间的关联尚不清楚。需要未来进行更大样本量的研究，使用经过验证的方法来测量久坐行为，以阐明久坐行为与老年人心血管结局之间的关联。
