BACKGROUND
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.
OBJECTIVE
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.
SETTING
University of São Paulo Medical School, Brazil; Public Practice.
METHODS
Functional capacity was assessed by 6MWD and body composition (%) by bioelectrical impedance analysis in 90 patients.
RESULTS
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.
CONCLUSIONS
Total and segmental FFM is associated with a better walking capacity than BMI.
背景
肥胖因机械因素和过多体脂而与活动能力下降相关。六分钟步行试验（6MWT）已被用于评估重度肥胖患者的功能能力。
目的
根据性别和肥胖等级，确定体重指数（BMI）、全身及各部位身体成分与六分钟步行试验（6MWT）期间步行距离（6MWD）之间的关联。
地点
巴西圣保罗大学医学院；公共实践。
方法
对90例患者进行6MWD评估功能能力，并通过生物电阻抗分析评估身体成分（%）。
结果
男女的平均6MWD为514.9±50.3米。男性组（M：545.2±46.9米）的6MWD高于女性组（F：505.6±47.9米）（p = 0.002）。病态肥胖组（MO：524.7±44.0米）的6MWD也高于超级肥胖组（SO：494.2±57.0米）（p = 0.014）。6MWD与去脂体重（FFM）、上肢FFM（FFM_UL）、躯干（FFM_TR）和下肢（FFM_LL）之间存在正相关。女性组6MWD与FFM、FFM_UL和FFM_LL之间存在正相关，男性组6MWD与FFM_TR之间存在正相关。在病态肥胖组中，6MWD与FFM、FFM_UL、FFM_TR和FFM_LL之间存在正相关。超级肥胖组6MWD与FFM、FFM_TR和FFM_LL之间存在正相关。
结论
全身及各部位的FFM比BMI与更好的步行能力相关。
