Morbid obesity is associated with alterations in the ability to walk, however, the behavior of the 6-minute walk test in subjects with increases in body mass index is unknown.
To describe the behavior of the 6-minute walk test in subjects with normal body mass index to morbid obesity.
Through an analytical cross-sectional design, subjects of both genders from 18 to 60 years old with body mass index were studied: Normal (BMI:18.5-24.9); overweight (BMI:25-29.9); obesity (BMI:30-39.9); morbid obesity (BMI:>40) kg/m. A 6-minute walk test was performed, demographic variables and pathological personal history were delimited. BMI categories were analyzed with one-way ANOVA and Bonferroni adjustment, and gender with t-test, both for independent groups, and Pearson's correlations for the various variables.
480 subjects of both genders were studied in four groups. Age: men 43 ± 11 and women 45 ± 10 years old. Percentage diabetes (6.7%), arterial hypertension (18.3%). Meters walked men vs. women by body mass index (normal: 483 ± 56 vs. 449 ± 61; overweight: 471 ± 55 vs. 441 ± 44; obesity: 455 ± 70 vs. 421 ± 47; morbid obesity: 443 ± 49 vs. 403 ± 54, p < 0.05). Correlation body mass index-meters walked: r: -0.446 (p < 0.0001).
Meters walked in the 6-minute walk test decreased as body mass index increased. The male gender walked more meters in all categories.
病态肥胖与行走能力的改变有关，然而，体重指数增加的受试者6分钟步行试验的表现尚不清楚。
描述体重指数正常至病态肥胖受试者的6分钟步行试验表现。
通过分析性横断面设计，对18至60岁、具有以下体重指数的男女受试者进行研究：正常（BMI：18.5 - 24.9）；超重（BMI：25 - 29.9）；肥胖（BMI：30 - 39.9）；病态肥胖（BMI：>40）kg/m²。进行6分钟步行试验，界定人口统计学变量和个人病史。对独立组采用单因素方差分析和Bonferroni校正分析BMI类别，采用t检验分析性别，并对各种变量进行Pearson相关性分析。
在四组中研究了480名男女受试者。年龄：男性43±11岁，女性45±10岁。糖尿病患病率（6.7%），动脉高血压患病率（18.3%）。按体重指数划分男性与女性行走的米数（正常：483±56 vs. 449±61；超重：471±55 vs. 441±44；肥胖：455±70 vs. 421±47；病态肥胖：443±49 vs. 403±54，p<0.05）。体重指数与行走米数的相关性：r：-0.446（p<0.0001）。
6分钟步行试验中行走的米数随着体重指数的增加而减少。在所有类别中男性行走的米数更多。
