A total of 179 elderly hospitalized patients were investigated by using general information questionnaire with demographic and health characteristics, Pittsburgh Sleep Quality Index Scale, Kessler Mental Disorders Scale and Frailty Phenotype. The prevalence of sleep disturbance, poor mental condition and frailty were 84.92%, 76.54% and 74.86% respectively. Mental health status partially mediated the association between sleep quality and frailty. Therefore, improving sleep quality and mental health status of elderly hospitalized patients is an effective way to prevent and delay frailty.
