Introduction: To assess the long-term consequences of coronavirus disease (COVID-19) among health care workers (HCWs) in China (hereafter surviving HCWs). Methods: A total of 303 surviving HCWs were included. Lung (pulmonary function test, 6-min walk test [6MWT], chest CT), physical (St. George's Respiratory Questionnaire [SGRQ], Modified Medical Research Council dyspnea scale [mMRC], and Borg scale), and psychiatric functions (Essen Trauma Inventory) were evaluated during the 1-year follow-up. Results: Surviving HCWs had an abnormal diffusion capacity 1 year post-discharge. Participants with a reduced carbon monoxide diffusing capacity (DLCO) comprised 43.48%. The proportion of HCWs with a median 6MWT distance below the lower limit of the normal was 19.4%. An abnormal CT pattern was observed in 37.5% of the HCWs. The SGRQ, mMRC, and Borg scores of surviving HCWs, especially those with critical/severe disease, were significantly higher than those in the normal population. Probable post-traumatic stress disorder (PTSD) was reported in 21.9% of the surviving HCWs. Diffusion capacity impairment was associated with women. Critical/severe illness and nurses were associated with impaired physical function. Conclusions: Most surviving HCWs, especially female HCWs, still had an abnormal diffusion capacity at 1 year. The physical and psychiatric functions of surviving HCWs were significantly worse than those of the healthy population. Long-term follow-up of pulmonary, physical, and psychiatric functions for surviving HCWs is required. [ABSTRACT FROM AUTHOR]

• Seven latent statuses of physical function were identified. • Physical function decline progress in some typical stages. • Indicative limitation and transition trend are useful for developing preventive intervention and tailored care for physically limited elderly. Multiple limitations often co-occur and accumulate, leading to subsequent function decline. However, there is a scarcity of longitudinal studies examining the progression of physical function among the general population of older adults in China. This study aimed to define typical physical function status and its change, which were characterized by the coexistence and accumulation of diverse limitations targeting a Chinese sample of older adults. This study used the three recent public data waves of the Chinese Longitudinal Healthy Longevity Survey during a 6-year follow-up period. 9765 individuals who were over 65 and participated in the 2011 survey were included. Latent transition analysis was used to identify the latent physical function status and explore the transition of older adults among different latent statuses. Seven latent statuses of physical function were identified, with visual impairment and related limitations being particularly prevalent among older adults. Upper limb mobility appeared to be a differentiated indicator of physical functional status. Physical function decline mainly started with the limitations in squatting, carrying weights and walking, then to the status with intact upper limb mobility and hearing function only, or converted directly into the latter, then to complete dysfunction. Our findings suggest some indicative limitations and critical steps in the process of functional decline among older adults. These results may provide insight for researchers and policymakers to develop tailored preventive and rehabilitation care and provide support for physically limited elderly according to their latent status and course of functional decline.
