Aims: The aim of our study was to investigate the relationship among sarcopenic obesity, physical performance, disability, and quality of life in a rehabilitation setting. Methods: Participants were recruited among obese patients (BMI > 30 kg/m2) admitted to the rehabilitation facility at the Department of Experimental Medicine, Medical Physiopatology, Food Science and Endocrinology Section during a 1-year period. A multidimensional evaluation was performed through bioelectrical impedance analysis and anthropometry, handgrip strength test, Short Physical Performance Battery (SPPB), 6-minute walk test (6MWT) and blood chemistry parameters. Psychological status (SCL-90 questionnaire), quality of life, and comorbidity (Charlson comorbidity index score) were also evaluated. Obesity was diagnosed as increased fat mass by 35% in women and by 25% in men. Sarcopenia was defined if lean body mass (LBM) was <90% of the subject’s ideal LBM. Results: 79 patients (48 women and 31 men;mean age: 60.1 ± 11.5 years, and 58.6 ± 10.8 years, respectively) were enrolled. Results showed a high prevalence of SO (54.4%) in our samples of obese subjects. Sarcopenia was present not only among older obese adults but also among younger obese subjects, and was related to reduced functional performance, to inflammatory status and to worse psychological status and quality of life.展开更多

Body composition as well as medications, physical parameters, blood samples, disease pattern, and smoking were considered. RESULTS: RMR was significantly associated with body weight(r = 0.732, P < 0.001), body height(r = 0.401,P = 0.008), BMI(r = 0.504, P < 0.001), waist circumference(r = 0.602, P < 0.001), mid-upper arm circumference(r = 0.417, P = 0.006), mid-upper arm muscle circumference(r = 0.344, P = 0.028), total body water(r = 0.339, P = 0.035), body temperature(r = 0.409, P = 0.007), smoking(P = 0.031), serum T4 levels(r = 0.331, P = 0.036), obstructive sleep apnoea syndrome(OSAS; P = 0.023), impaired glucose tolerance(IGT; P = 0.017) and impaired glycaemic status, including hyperinsulinism, IGT and diabetes mellitus(P = 0.003).CONCLUSION: Future research should be prompted to optimize the procedure of indirect calorimetry to achieve clinical benefits in obese subjects.展开更多
