ABSTRACT
Background: Early in the epidemic of corona virus disease 2019 (COVID-19), Chinese government had recruited a portion of military healthcare workers to support the designated hospital (Wuhan Huoshenshan Hospital) to relieve the front-line workload in Wuhan, China. It was reported that the majority of the front-line medical staff (FLMS) suffered from adverse effects, but their physical and psychological health status and its relationship were still unknown. Hence, a structural equation modeling (SEM) was conducted to establish and test the latent relationship among variables.Methods: This is a cross-sectional study. Totally 115 convenience samples of military medical staff from Xinqiao Hospital in Chongqing were enrolled during February 17th to February 29th, 2020. The medical staff assisting in Huoshenshan Hospital were selected as experimental group(n=55), the other medical staff were control group(n=60). Self-reported sleep status, fatigue status, resilience status and anxiety status were examined.Results: During COVID-19, the medical staff underwent some impairments of physical and psychological health. The anxiety score of experimental group was (42.84±9.44), the fatigue score was (52.85±9.33), and the resilience score was (67.58±11.75). And the score of anxiety, fatigue, resilience of control group were (46.27±9.94), (49.33±11.20), (65.42±14.54) respectively. For experimental group, we found the different working duration and different attitude to work in Wuhan both had significant differences in fatigue scores (P<0.05); As for resilience scores and anxiety scores, only different current perceived health status of participants showed a statistically significant difference (P<0.05). The SEM results indicated the direct path from resilience to fatigue (β=-0.129, P=0.032) and anxiety (β=-0.026, P=0.043) were both significant, it revealed that resilience were negatively associated with the level of fatigue and anxiety, and the indirect path showed fatigue had a significant mediating effect between resilience and anxiety (β=-0.146, P=0.039) of the Huoshenshan Hospital medical staff.Conclusion: During an explosive pandemic, motivating the effect of individual’s internal resilience and making use of proper external interventions is a promising way to protect the physical and mental health of the front-line medical staff.
