Purpose: The study aimed to investigate the association between body composition and frailty in elder inpatients. Patients and Methods: This is a cross-sectional study including 656 elder inpatients (275 females and 381 males) aged ≥ 65 years, from department of geriatrics of Zhejiang Hospital between January 2018 and March 2019. Sociodemographic, health-related data and anthropometric measurements were evaluated. Body composition was assessed by bioimpedance analysis (BIA), mainly including skeletal muscle mass, body fat mass, total body water, fat-free mass,percent body fat, basal metabolic rate. Frailty was assessed by Clinical Frailty Scale (CFS). Univariate logistic regression was used to analyze the association between body composition and frailty. Results: Frailty was present in 43.9% of the participants. Frail inpatients showed higher waist circumference, body fat mass and percent body fat, non-frail inpatients showed greater upper arm circumference, calf circumference, skeletal muscle mass, total body water, fat-free mass and basal metabolic rate. Subjects with underweight (body mass index (BMI)< 18.5 kg/m 2 ; odds ratio (OR), 95% confidence interval (CI)=4.146 (1.286– 13.368) P=0.017) and those with high waist circumference (OR 95% CI=1.428 (0.584– 3.491) P< 0.001), body fat mass (OR, 95% CI=1.143 (0.892– 1.315) P< 0.001) presented a higher risk of frailty compared to normal subjects. Skeletal muscle mass (OR; 95% CI=0.159 (0.064– 0.396) P< 0.001) was a protective f...
