    The aim of this study was to examine the short-term changes in disability after an inpatient, multidisciplinary body weight reduction program (BWRP) in adults with obesity. A total of 160 individuals (males: 52, females: 108, BMI > 35 kg/m2) hospitalized for a 3-week multidisciplinary BWRP were recruited into the study. Body composition, lower limb muscle power, fatigue severity, and disability were measured at the beginning and end of the intervention by means of bioimpedance analysis, a stair climbing test (SCT), the Fatigue Severity Scale (FSS), and the Oswestry disability index (ODI), respectively. At the end of the 3-week BWRP, an average body weight reduction of 5.0 kg (CI 95% −5.3; −4.6, p < 0.001) was determined, as well as an improvement in all parameters measured. Clinically meaningful reductions in disability were observed in the moderate disability (Δ = −11.8% CI 95% −14.3; −9.3, p < 0.001) and severe disability (Δ = −15.9% CI 95% −19.6; −12.2, p < 0.001) groups. Reductions in disability were explained only by improvements in the SCT (Δ = −2.7 CI 95% −4.1; −1.4, p < 0.001) and the FSS (Δ = −0.3% CI 95% −0.4; −0.1, p < 0.001). These findings demonstrate the importance of incorporating approaches into a BWRP that increase lower limb muscle power and decrease fatigue severity and thus reduce disability in adults with obesity.

    Background: Low back pain is one of the most prevalent musculoskeletal problems and continues to be the leading cause of disabilities worldwide. The aim of this study was to cross-sectionally investigate the association of physical performance with mental and physical health-related quality of life and low back pain-related disabilities among older adults with severe obesity. Methods: A total of 96 hospitalized older adults with severe obesity (45 males, 51 females, age: 69.7 ± 5.4 years; BMI: 43.7 ± 5.7 kg/m2) were recruited into the study. Physical performance, health-related quality of life, and low back pain-related disability were measured through physical performance tests, the 12-item short-form survey (SF-12), and the Oswestry disability index, respectively. Results: LBP-related disabilities, as well as physical health-related quality of life, were associated with all the physiological parameters measured by physical performance tests, including muscular strength, aerobic capacity, balance, and lower body flexibility (p < 0.05). In contrast, mental health-related quality of life was associated with fewer physiological parameters, such as primarily muscular strength (p < 0.05). Conclusions: These findings could provide important insights for developing rehabilitation strategies designed to improve LBP-related disabilities, as well as the physical and mental health-related quality of life, in older adults with severe obesity.
