Six minute walk test: from normal to morbid obesity subject

Résumé fourni par la source

Introduction: 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.Objective: To describe the behavior of the 6-minute walk test in subjects with normal body mass index to morbid obesity.Methods: 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 2 .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.Results: 480 subjects of both genders were studied in four groups.Age: men 43 ± 11 and women 45 ± 10 years old.Percentage diabetes mellitus (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).Conclusions: Meters walked in the 6-minute walk test decreased as body mass index increased.The male gender walked more meters in all categories.
