Objective The purpose of this study was to obtain the infection
status, exercise, anxiety and sleep quality of some Chinese residents
who recovered from infection during the COVID-19 pandemic, explore the
influencing factors of recovery status, and help improve the
intervention measures for COVID-19 recovery. Methods This study
is a sub-study, nested within a cross-sectional study, investigating the
infection and physical and mental health of partially recovered
residents in all 34 provincial areas of China during the COVID-19
epidemic. Results There were 1013 participants in this study,
including 374 males and 639 females. The cardiopulmonary endurance after
infection was significantly lower than that before infection
(P<0.01). Among all participants, women (3.92±4.97) had more
anxiety than men (3.33±4.54, P<0.01); The sleep score after
infection (8.27±7.05) was significantly higher than that before
infection (4.17±4.97, P<0.01). The days of fever remission in
regular exercise and sedentary group were significantly shorter than
those in irregular exercise and sedentary group (P<0.05). The
days of fever remission in regular exercise group (1.81±1.91) was
significantly shorter than that in irregular exercise group (2.02±1.95,
P<0.05). The number of negative days in the non-sedentary
group (7.32±3.24) was significantly lower than that in the sedentary
group (7.66±3.06, P<0.05). Conclusions In this study,
it was observed that the recovery time of symptoms after COVID-19
recovery was related to age, and the more symptoms there were, the worse
cardiopulmonary fitness and sleep quality would be. Sedentary people and
irregular exercise people generally took a longer time to turn negative.
Therefore, appropriate exercise, psychological and sleep hygiene and
other health interventions should be considered in COVID-19 recovery
measures.
