摘　　要：Background:This study evaluated physical fitness and mental health in young and elderly women 3 months after mild COVID-19 infection,and examined the impact of infection and age on long COVID occurrence and trajectory.Methods:There were 213 eligible female volunteers(107 young,106 elderly)recruited approximately three months after the significant outbreak of COVID-19 in China.Participants completed a fitness test and mental health assessment using the Post-Traumatic Stress Disorder Self-Assessment Scale(PTSD)and the Pittsburgh Sleep Quality Inventory(PSQI).Results:Despite no significant difference in physical fitness,infected young and elderly females experienced poorer sleep quality related to mental health compared to their uninfected peers(+22%in young participants,p=0.027;+10%in elderly participants,p=0.005).The elderly scored significantly higher in sleep quality than the young(p<0.05).Age,previous infection,and PTSD were significant predictors of sleep quality,explaining 60.6%of the variance in PSQI scores.Conclusions:Three months following COVID-19 infection,infected women experienced poorer sleep quality compared to their uninfected peers.Irrespective of being infected,older individuals exhibited higher rates of sleep disorders compared to younger women,suggesting the importance of addressing postCOVID-19 sleep issues among at-risk individuals.
