Alcaraz-Serrano V, Gimeno-Santos E, Scioscia G, et al. - Researchers undertook this prospective observational analysis to examine the link between any physical activity (PA) variable and sedentary time with hospitalisation because of exacerbation among adults having bronchiectasis. The participants included 64 patients in total, among those, hospitalization during the observation period was reported in 15 (23%). Experts determined baseline lung function, quality of life, exercise tolerance, severity of bronchiectasis and PA. Findings revealed a link of low levels of PA and high sedentary time at baseline with a risk of hospitalisation attributed to bronchiectasis exacerbation. At 1-year follow-up, an increased risk of hospital admission because of bronchiectasis exacerbation was observed among patients who walked ≤ 6290 steps per day or spent ≥7.8 h per day in sedentary behaviour. Particularly, a 5.9-fold higher risk of hospital admission in the following year was observed in correlation with ≥7.8 h of sedentary behaviour. The inclusion of PA and sedentary behaviour as an item in severity scores might be appropriate after validation of these results in future investigations.
