The purpose of the current study was to determine the association between sedentary time and physical activity with clinically relevant health outcomes among adults with impaired spirometry and those with or without self-reported obstructive lung disease (asthma or COPD).
Data from participants of the Canadian Longitudinal Study on Aging were used for analysis (n = 4156). Lung function was assessed using spirometry. Adults were said to have impaired spirometry if their Forced Expiratory Volume in 1 s was <5th percentile lower limit of normal (LLN). A modified version of the Physical Activity Scale for the Elderly was used to assess sitting time and physical activity levels. Healthcare use and quality of life outcomes were assessed using self report.
Among those with asthma, participating in strengthening activities was associated with lower odds of reporting poor perceived health (OR = 0.65, CI: 0.53, 0.79), poor perceived mental-health (OR = 0.73, CI: 0.60, 0.88), unhealthy aging (OR = 0.68, CI: 0.56, 0.83), and reporting an emergency department visit in the past 12 months (OR = 0.76, CI: 0.60, 0.95). Among those with COPD, those who reported highest weekly sedentary time had higher odds of reporting poor perceived health (OR = 2.70, CI: 1.72, 4.24), poor perceived mental-health (OR = 1.99, CI: 1.29, 3.06), and unhealthy aging (OR = 3.04, CI: 1.96, 4.72). Among those below the LLN, sitting time (OR = 2.57, CI: 1.40, 4.72) and moderate intensity physical activity (OR = 0.23, CI: 0.09, 0.63) were associated with overnight hospital stays.
Higher physical activity levels and lower sedentary time may be associated with lower healthcare use and better quality of life. This research may have implications related to the use of physical activity for improving health outcomes and quality of life among adults with obstructive lung disease or impaired spirometry.
本研究旨在探讨成年人中，存在或不存在肺功能障碍（哮喘或 COPD）的肺功能受损和体力活动与临床相关健康结果之间的关系。
使用加拿大老龄化纵向研究的数据进行分析（n=4156）。通过肺活量测定法评估肺功能。如果用力呼气量在 1 秒内<正常第 5 百分位数下限（LLN），则认为成年人的肺功能受损。使用经过改良的老年人体力活动量表来评估久坐时间和体力活动水平。使用自我报告来评估医疗保健使用情况和生活质量结果。
在哮喘患者中，参加强化活动与报告健康状况较差（OR=0.65，CI：0.53，0.79）、心理健康状况较差（OR=0.73，CI：0.60，0.88）、衰老不健康（OR=0.68，CI：0.56，0.83）和在过去 12 个月内就诊急诊的可能性较低（OR=0.76，CI：0.60，0.95）的可能性降低有关。在 COPD 患者中，每周久坐时间最高的患者报告健康状况较差（OR=2.70，CI：1.72，4.24）、心理健康状况较差（OR=1.99，CI：1.29，3.06）和衰老不健康（OR=3.04，CI：1.96，4.72）的可能性更高。在低于 LLN 的患者中，久坐时间（OR=2.57，CI：1.40，4.72）和中强度体力活动（OR=0.23，CI：0.09，0.63）与夜间住院有关。
更高的体力活动水平和更低的久坐时间可能与更低的医疗保健使用和更好的生活质量相关。这项研究可能与使用体力活动改善有阻塞性肺病或肺功能受损的成年人的健康结果和生活质量有关。
