Abstract:
Objective To investigate the fatigue and workload status among medical students,and to explore the latent profiles of fatigue and workload and their effects on sleep and emotion.Methods A cross-sectional study design with convenience sampling was employed to distribute a comprehensive survey via mixed online and offline modes,and medical college students were enrolled as the subjects for this investigation.The general demographic data,depression,anxiety and stress scale,Pittsburgh sleep quality index,Epworth sleepiness scale,insomnia severity index,National Aeronautics and Space Administration task load index(NASA-TLX)and fatigue scale-14(FS-14)were used to investigate the basic information of the medical students,their emotions(depression,anxiety and stress),sleep(sleep quality,sleepiness and insomnia),workload and fatigue status.Based on latent profile analysis,the types of workload-fatigue profiles and differences in sleep and emotion were analyzed.Results A total of 485 medical students were enrolled,with an average age of(22.07±2.42)years.The total score of the NASA-TLX was 64.44±12.50,and the total score of the FS-14 was 7.90±3.63.Latent profile analysis identified 3 distinct workload-fatigue profiles:low workload-medium fatigue group(12.8％),medium workload-low fatigue group(32.8％),and high workload-high fatigue group(54.4％).Among these,the medium workload-low fatigue group exhibited the highest performance level(all P＜0.05),while the low workload-medium fatigue group showed the lowest effort level and performance level(all P＜0.05).The high workload-high fatigue group showed the highest task-related demand and frustration level(all P＜0.05).Regarding sleep and emotional status,the medium workload-low fatigue group had significantly better outcomes compared to the high workload-high fatigue group and the low workload-medium fatigue group(all P＜0.05).Conclusion Medical students experience a heavy workload and subjective fatigue.It is essential to appropriately adjust their workload,prioritize sleep and emotional well-being,and alleviate fatigue levels,so as to sustain personal physical and mental health.
