Background: In 2009, the Italian Society of Obesity developed the short-form questionnaire for Obesity-related Disabilities (TSD-OC). Aims: To stage the degree of disability in obese patients using TSD-OC; to verify its sensitivity to change after rehabilitation. Subjects: Three hundred and fifty-five adult obese individuals [body mass index (BMI) >30 kg/m 2] undergoing rehabilitation. Exclusion criteria were severe cardiovascular or respiratory diseases, neurological and psychological conditions. Sensitivity to change of TSD-OC was evaluated in 194 patients out of the initial sample. Methods: To define the disability levels according to TSD-OC, the method of interquartile range was applied to the initial sample. The 194 in-patients were assessed with Roland-Morris Disability Questionnaire, Functional Independence Measure (FIM), Functional Visual Analogue Scale, and TSD-OC before (S0) and after 4 weeks (S1) of intensive (3 h daily) rehabilitation multidisciplinary program. Individuals were grouped according to age (1: age 30-59 yr; 2: age over 60 yr) and degree of obesity (BMI: A, 30-40 kg/m2; B, 40-50 kg/m2). Results: At S1, BMI and all the clinical scores improved significantly in the whole study sample. The younger individuals with higher level of obesity showed a higher functional improvement (-51.3%). In the older subjects, improvement was not statistically different when varying BMI (A2 -13.7% vs B2 -14.6%). In the whole group, the TSD-OC improvement was statistically greater than the physical FIM gain (-25.9% vs +5.4%, p<0.05). Conclusions: Our data evidenced that the TSD-OC is a sensitive measure of short-term changes in disability status of obese individuals after rehabilitation. Source

Purpose: The 6-Min Walking Test (6MWT) is widely used to measure the performance in various chronic conditions, such as in obese subjects. Reference equations for predicting distance walked during 6MWT specifically in adult obese subjects are not available. The aim of the paper is to establish reference values for 6MWT in an adult obese population. Methods: 323 obese patients (body mass index: BMI > 30kg/m, age range 20-60 years) admitted to our hospital for multidisciplinary rehabilitation and weight reduction programs were evaluated using 6MWT, heart rate, blood pressure, oxygen saturation, anthropometric measurements and level of dyspnoea were considered as outcome measure. Results: Distance walked during the 6MWT was significantly correlated to age, gender and BMI. The proposed reference equation is: 6MWTm = 894.2177 - (2.0700 × ageyrs) - (51.4489 × gendermales = 0; females = 1) - 5.1663 × BMIKg/m2. In the multiple linear regression analysis age, gender and BMI explained 48% of the total variance in 6MWT. The average difference between predicted and measured 6MWT values (11.33±52.98 m) did not reach statistical significance and the correlation was significant (r = 0.698). Conclusions: A reference equation specific for the obese population was provided; it can be used as realistic benchmark in the rehabilitation setting to assess functional capacity, plan exercise intensity and monitor changes over time. Implications for Rehabilitation The 6-Min Walking Test (6MWT) is generally used to measure functional capacity in various chronic conditions. Obesity is associated with reduced aerobic capacity and mobility disability but no reference equations for predicting distance walked during 6MWT are present. This study provides reference values specific for the obese population. © 2013 Informa UK, Ltd. Source
