Abstract
The impact of COVID-19 on lung function and sleep in otherwise healthy individuals has been subject to a limited number of studies. The aim of this study was to investigate the effect of COVID-19 on pulmonary function and sleep in adults. Participants, 50–85 years old, who had recovered from COVID-19 (COVID-19 group: n = 48) and those without history of COVID-19 (control group: n = 28) underwent pulmonary function assessment (Forced Vital Capacity, FVC, and Slow Vital Capacity, SVC) using spirometry. Sleep and circadian variables were measured objectively with wrist-worn actigraphy for seven days. Subjective sleep of participants was assessed using the Pittsburgh Sleep Quality Index (PSQI). There were no significant differences in age (60 ± 6 vs 62 ± 6 years), BMI (26.30 ± 4.25 vs 26.48 ± 3.60 kg/m2), or pulmonary function (FVC, 4.02 ± 1.04 vs 3.80 ± 0.98 L, p = 0.36; and SVC, 3.82 ± 1.09 vs 3.89 ± 0.92 L, p = 0.76) between COVID-19 and control groups. The COVID-19 group had significantly reduced sleep efficiency (0.87 ± 0.04 vs 0.91 ± 0.04, p < 0.01), increased sleep disturbance (awakenings, 1.70 ± 1.02 vs 1.15 ± 1.15, p < 0.01; and wakefulness after sleep onset, 35:05 ± 25:37 vs 20:02 ± 12:48 min, p = 0.01) and PSQI score (5.19 ± 2.88 vs 3.93 ± 2.89, p = 0.01), compared to the control group. Individuals with history of COVID-19 demonstrate reduced sleep quality compared to a non-COVID-19 control group.
