The relationship between BMI and frailty status
Frailty was diagnosed by the QMCOO cutoff of 4 scores or over. The participants into three groups based on the body mass index (BMI): “lean” (BMI < 18.5 kg/m2), “standard” (18.5 ≤ BMI < 25.0 kg/m2), and “obese” (BMI ≥ 25.0 kg/m2).
(A) The ratio of the frailty of lean, standard, and obese groups in total participants. (B) The ratio when the participants were divided into males and females. (C) The ratio when the participants were divided into three groups of “74 or under”, ”75–84”, and ”85 or over”
(D) Logistic regression analysis to evaluate factors on frailty
