Correlation between Body Composition and Walking Capacity in Severe Obesity
<div><p>Background</p><p>Obesity is associated with mobility reduction due to mechanical factors and excessive body fat. The six-minute walk test (6MWT) has been used to assess functional capacity in severe obesity.</p><p>Objective</p><p>To determine the association of BMI, total and segmental body composition with distance walked (6MWD) during the six-minute walk test (6MWT) according to gender and obesity grade.</p><p>Setting</p><p>University of SĂ£o Paulo Medical School, Brazil; Public Practice.</p><p>Methods</p><p>Functional capacity was assessed by 6MWD and body composition (%) by bioelectrical impedance analysis in 90 patients.</p><p>Results</p><p>The mean 6MWD was 514.9 ± 50.3 m for both genders. The male group (M: 545.2 ± 46.9 m) showed a 6MWD higher (p = 0.002) than the female group (F: 505.6 ± 47.9 m). The morbid obese group (MO: 524.7 ± 44.0 m) also showed a 6MWD higher (p = 0.014) than the super obese group (SO: 494.2 ± 57.0 m). There was a positive relationship between 6MWD and fat free mass (FFM), FFM of upper limps (FFM_UL), trunk (FFM_TR) and lower limbs (FFM_LL). Female group presented a positive relationship between 6MWD and FFM, FFM_UL and FFM_LL and male group presented a positive relationship between 6MWD and FFM_TR. In morbid obese group there was a positive relationship between 6MWD with FFM, FFM_UL, FFM_TR and FFM_LL. The super obese group presented a positive relationship between 6MWD with FFM, FFM_TR and FFM_LL.</p><p>Conclusions</p><p>Total and segmental FFM is associated with a better walking capacity than BMI.</p></div
