This study aimed to estimate the prevalence of frailty and associated factors among hospitalized older adults. It consisted of 184 hospitalized older adults recruited between October 2019 to January 2020. We used the FRAIL scale, Geriatric Depression Scale–15, and the Pittsburg Sleep Quality Index to collect data. Descriptive statistics, independent group t -test, Chi-square (χ~(2)) tests, and logistic regression were applied to statistical analysis. It found that the prevalence of frailty among hospitalized older adults was 39.7%. Depression (Mild: OR ?=?5.312, 95% CI [2.384–11.833]; Moderate: OR ?=?6.630, 95% CI [2.077–21.160]) and low activities of daily living (ADL) (Slight dependence: OR ?=?5.667, 95% CI [1.308–24.557]; Moderate dependence: OR ?=?15.188, 95% CI [3.342–69.016]; Severe dependence: OR ?=?5.872, 95% CI [2.645–13.038]) were independent predictors of frailty. Future studies on the interventions to reduce depression, improve ADL and delay the progression of frailty are encouraged. We should focus more on ADL, emotional and psychological state of hospitalized older adults to prevent frailty.
