This study sought to examine the association between inactive time, leisure-time physical activity and mortality in individuals diagnosed with chronic obstructive pulmonary disease.
This study utilized a nationally representative sample of patients with chronic obstructive pulmonary disease from National Health and Nutrition Examination Survey ( n = 1817; weighted population, 23,698,840). Mortality was tracked from the date of interview and examination. Leisure-time physical activity and sedentary time were assessed using a Global Physical Activity Questionnaire.
The study found that only 28% of patients with chronic obstructive pulmonary disease achieved sufficient leisure-time physical activity (leisure-time physical activity ≥150 mins/wk), while 58% reported no physical activity and 47% sat for over 6 hrs per day. Over a 9-yr follow-up period, 501 deaths occurred, with 101 due to heart diseases. Adequate leisure-time physical activity levels were associated with a decreased risk of mortality from any cause. Moreover, patients who engaged in sufficient leisure-time physical activity and reduced sitting time had a lower risk of mortality from any cause compared to those who did not engage in sufficient leisure-time physical activity.
Participating in an adequate amount of leisure-time physical activity was linked to a reduced risk of death from any cause in patients with chronic obstructive pulmonary disease. However, irrespective of the extent of the leisure-time physical activity, there was no significant correlation between sedentary behavior and the risk of mortality.
本研究旨在探讨慢性阻塞性肺疾病患者的非活动时间、休闲时间身体活动与死亡率之间的关联。
本研究使用了来自国家健康与营养检查调查的具有全国代表性的慢性阻塞性肺疾病患者样本（n = 1817；加权人口为23,698,840）。从访谈和检查日期开始跟踪死亡率。使用全球身体活动问卷评估休闲时间身体活动和久坐时间。
研究发现，只有28%的慢性阻塞性肺疾病患者有足够的休闲时间身体活动（休闲时间身体活动≥150分钟/周），而58%的患者表示没有身体活动，47%的患者每天久坐超过6小时。在9年的随访期内，发生了501例死亡，其中101例死于心脏病。充足的休闲时间身体活动水平与任何原因导致的死亡风险降低相关。此外，与没有进行足够休闲时间身体活动的患者相比，进行了足够休闲时间身体活动且减少了久坐时间的患者因任何原因导致的死亡风险更低。
参与适量的休闲时间身体活动与慢性阻塞性肺疾病患者任何原因导致的死亡风险降低有关。然而，无论休闲时间身体活动的程度如何，久坐行为与死亡风险之间均无显著相关性。
