Low physical activity and high sedentary behaviour in patients with bronchiectasis are associated with hospitalisation over one year. However, the factors associated with longitudinal changes in physical activity and sedentary behaviour have not been explored. We aimed to identify clinical and sociodemographic characteristics related to a change in physical activity and sedentary behaviour in patients with bronchiectasis after one year.
This was a prospective observational study during which physical activity measurements were recorded using a SenseWear Armband for one week at baseline and at one year. At each assessment point, patients were classified as active or inactive (measured as steps per day) and as sedentary or not sedentary (measured as sedentary time).
53 patients with bronchiectasis were analysed, and after one year, 18 (34%) had worse activity and sedentary levels. Specifically, 10 patients became inactive and sedentary. Multivariable analysis showed that the number of exacerbations during the follow-up period was the only outcome independently associated with change to higher inactivity and sedentary behaviour (odds ratio (OR), 2.19; 95% CI, 1.12 to 4.28).
The number of exacerbations in patients with bronchiectasis was associated with changes in physical activity and sedentary behaviour. Exacerbation prevention may appear as a key factor in relation to physical activity and sedentary behaviour in patients with bronchiectasis.
支气管扩张症患者身体活动量低和久坐行为多与一年中的住院治疗相关。然而，与身体活动和久坐行为的纵向变化相关的因素尚未得到探究。我们旨在确定与支气管扩张症患者一年后身体活动和久坐行为变化相关的临床和社会人口学特征。
这是一项前瞻性观察性研究，在此期间，使用SenseWear臂带在基线和一年时记录一周的身体活动测量值。在每个评估点，患者被分类为活跃或不活跃（以每天步数衡量）以及久坐或不久坐（以久坐时间衡量）。
对53例支气管扩张症患者进行了分析，一年后，18例（34%）患者的活动和久坐水平变差。具体而言，10例患者变得不活跃且久坐。多变量分析显示，随访期间的急性加重次数是唯一与更高程度的不活动和久坐行为变化独立相关的结果（比值比（OR），2.19；95%置信区间，1.12至4.28）。
支气管扩张症患者的急性加重次数与身体活动和久坐行为的变化相关。预防急性加重可能是支气管扩张症患者身体活动和久坐行为的一个关键因素。
