The purpose of this study was to verify the influence of physical activity level on the length of hospital stay in older men recovered from COVID-19. In total, 126 older men diagnosed with COVID-19 were admitted to the hospital between September and December 2020. Among them, 70 survived, of which 39 older men were included in the study. Within 30 days after discharge, patients answered the International Physical Activity Questionnaire to measure their physical activity level through phone contact, with questions corresponding to the week before symptom onset. Clinical and laboratorial data from admission, days between onset of symptoms and admission, length of stay, computed tomography abnormalities, and the need for the intensive care unit were collected. The groups (active × sedentary) were compared using the Student t test or Mann-Whitney test for quantitative data and chi-square test was used for categorical data. There is no difference between the groups in characteristics of admission ( > 0.05), except by potassium level. Active older men had a shorter length of stay (6.50 ± 3.46 vs 11.48 ± 7.63 days; = 0.03), disease duration (15.71 ± 4.84 vs 21.09 ± 7.69 days; = 0.02), and lower frequency of lung damage when compared to their sedentary counterparts. In conclusion, being physically active prior to infection can attenuate length of hospital stay in older men with COVID-19.
本研究的目的是验证身体活动水平对从 COVID-19 中康复的老年男性住院时间长短的影响。2020 年 9 月至 12 月期间，共有 126 名被诊断为 COVID-19 的老年男性入院。其中，70 人存活，其中 39 名老年男性被纳入研究。出院后 30 天内，患者通过电话联系回答国际身体活动问卷，以测量他们在症状出现前一周的身体活动水平。收集了入院时的临床和实验室数据、症状出现至入院的天数、住院时间、计算机断层扫描异常情况以及重症监护病房的需求。对于定量数据，使用 Student t 检验或 Mann-Whitney 检验比较各组（活跃组×久坐组），对于分类数据使用卡方检验。除钾水平外，各组入院特征之间无差异（>0.05）。与久坐的老年男性相比，活跃的老年男性住院时间更短（6.50±3.46 天对 11.48±7.63 天；=0.03），病程更短（15.71±4.84 天对 21.09±7.69 天；=0.02），肺部损伤频率更低。总之，感染前进行身体活动可以缩短 COVID-19 老年男性的住院时间。
