The populations with high prealbumin level, high grip strength, and high muscle strength were not easy to enter frailty period, while those with older age (OR = 1.141, 95% CI: 1.085-1.200), urinary incontinence (OR = 10.314, 95% CI: 1.950-54.548), urinary retention (OR = 3.058, 95% CI: 1.571-5.952), and constipation (OR = 3.004, 95% CI: 1.540-5.857) were easy to enter frailty period.The high incidence ages of frailty and prefrailty are 86 to 90 years old and 65 to 70 years old, respectively.
