The clinical and functional characteristics of patients with severe obesity who present for non-bariatric surgery have rarely been described. For this study, 293 such patients (mean body mass index 42 kg/m2) were investigated using their medical records, a 6-minute walk test, N-terminal pro B-type natriuretic peptide measurement, and the World Health Organization Disability Assessment Schedule 2.0 measure of disability. Cardiorespiratory disease and diabetes were common, with blood tests revealing a high probability of additional unexpected and undiagnosed renal and cardiac disease in a significant proportion of patients. One-third of patients had natriuretic peptide values that identify early left ventricular dysfunction in the community, with 16% above a value described as useful in predicting adverse outcomes for elective surgical patients. Only 10% of patients walked a distance within 10% of that predicted in six minutes, and 22% did not complete the test. Over one-third of patients (34%) had a clinically significant level of disability, with those unable to walk for six minutes describing higher levels of disability. Functional capacity as measured by the 6-minute walk test was significantly lower than would be expected from age, gender, and weight alone, and was related to age and degree of disability but not body mass index. We describe a severely obese population presenting for non-bariatric surgery who had significant levels of comorbid disease, functional impairment, and disability that were not apparent on routine preoperative assessment.

Background The self-paced six minute walk test is a simple assessment for sub-maximal functional capacity. It correlates well with sophisticated tests and gives good prediction for morbidity, mortality, quality of life and pulmonary functions.Objective To evaluate six minute walk distance in healthy adults to identify reference values and formulate reference equations.Method We conducted six minute walk test on 250 random volunteers at and above 18 years of age as per standard protocol. Age, gender, height and weight were measured. Pre-test and post-test vital parameters were recorded including pulse oximetry. The six minute walking distance was identified in all subjects. Multiple regression analysis was done to formulate regression equations to predict six minute walking distance. This also correlated age, gender, height, weight, body mass index with six minute walking distance.Result The mean six minute walking distance was 489±86 meters with males walking 509±82 meters and females 445±78 meters. Age, gender, weight and body mass index had significant contribution for prediction of six minute walking distance. Gender was the single most important predictor. Height had the least significance. Depending on coefficients of these variables we formulated three regression equations and tested them for accurate prediction. The two best equations were identified as: Predicted SMWD = 395–1.5xAge+2.47xWT–35.89xGender and Predicted SMWD = 440–1.82xAge–53.07xGender+5.12xBMI.Conclusion Gender, age and height are the most important predictors of six minute walking distance. Reference values and equations for both genders, different age groups with varying weights were derived for local population.

Purpose: This study attempted to establish reference values of the six-minute walk test (6MWT) for children (38 males; 38 females; age 90-108 months) and to determine the relationship between BMI and walking distance. Method: Subjects walked at a normal, self-selected, walking speed on a grassy field for six minutes, after which distance was measured. Results: Mean BMI was 15.50 (sd=2.00) for males and 16.30 (sd=2.90) for females. Mean walking distance was 581.70 m (sd=58.10) for males and 532.20 m (sd=52.60) for females. The partial correlation between BMI and distanced walked with the influence of gender removed was .10 (p > .05). The partial correlation between BMI and distanced walked with the influence of age removed was .02 (p > .05). There was no relationship between distance walked and BMI. Conclusions: Reference values of the six-minute walk test for healthy, third-grade school children were calculated and reported.walk test, pediatric BMI, body mass index, six minute walk test

Background: Few data are available on the capacity for functional exercise after cardiac rehabilitation in patients who have undergone coronary artery bypass graft (CABG) surgery. The aim of this study was to determine the clinical and biochemical factors that affect the 6-minute walk test (6MWT) results in patients who have undergone CABG.Methods: Data were prospectively collected from 56 patients consecutively admitted at our hospital between January 2013 and May 2015 for a 3-month cardiac rehabilitation program. Data were analysed retrospectively up to 90 days after cardiac surgery. In addition to clinical and biochemical parameters, the functional capacity of patients was evaluated by an exercise 6-minute walking test and echocardiography. Functional capacity was evaluated at baseline and after three months of cardiac rehabilitation. Results: Before cardiac rehabilitation, the 6MWT values were negatively correlated with Body Mass Index (BMI) and abdominal and buttock diameters (r = -0.375, -0.386, and -0.370, respectively; P < .05), and were positively correlated with metabolic equivalent (MET) values (r = 0.493, P < .05). After cardiac rehabilitation, the 6MWT values were negatively correlated with body mass index (BMI) and abdominal and buttock diameters (r = -0.382, -0.274, and -0.405, respectively; P < .05) and were positively correlated with MET and VO2 max values (r = 0.456 and 0.573, respectively; P < 0.05). Before cardiac rehabilitation, VO2 max and FEV1/FEVC values were found as factors that significantly increased 6MWT values (P < .05). After cardiac rehabilitation, VO2 max values were found as factors that significantly increased 6MWT values (P < .05).Conclusion: Overall, in current clinical settings, cardiac rehabilitation increases the reliability of the 6MWT. Improvement in pulmonary function after cardiac rehabilitation reduces the impact of pulmonary function on 6MWT values. The functional capacity of patients may be more reliably determined by 6MWT after cardiac rehabilitation.

Objective: To evaluate the role of obesity in the effects of physical activity (PA) on postural control and functional and physical capacities in the older adults and to assess the effectiveness of a PA program on these capacities. Methods: Six obese (age = 78.8 [3.7] y; body mass index > 30 kg/m2), 7 overweight (age = 80.9 [2.8] y; 25 < body mass index < 30 kg/m2), and 6 normal weight (age = 80.8 [5.7] y; body mass index < 25 kg/m2) older adults performed the time up and go test, the 6-minute walk test, and the Tinetti test. Static and dynamic (forward leaning) postural control tests were also assessed. All these tests were similarly assessed 4 months later, during which only the obese group and overweight group participated in a PA program. Results: Before PA, results of the time up and go test, 6-minute walk test, Tinetti test, quiet standing, and forward lean tests revealed that physical capacities and static and dynamic postural control were impaired in the obese group when compared to the normal weight group. After PA, results of quiet standing, physical and functional tests were improved for obese group. Conclusions: Obesity is an additional constraint to age-related postural control and functional and physical capacities deteriorations. Nevertheless, a PA program is effective in improving balance and functional capacities in obese older adults.
