This review focuses on some of the methodological and practical issues associated with the use of common body composition methods and identifies available published information on feasible methods for use in the severely obese. With the increasing prevalence of obesity and lifestyle diseases there is increased need for body composition methods with greater sensitivity and precision. Participants in the severe intervention lost 15 to 17 times as much weight waist circumference whole body fat mass and visceral adipose tissue compared to those in the moderate intervention and were 26 times more likely 42 versus 16 to have lost 10 or more of their. Second bmi assessment is the simplest method for assessing obesity. The aim of our study was to correlate the 6mwd with bmi total and segmental body composition in severe obesity according to gender and obesity grade. Class 3 obesity is sometimes categorized as extreme or severe obesity.
The physical size limitations imposed by severe obesity and variations in body composition from that of normal weight pose tremendous challenges to the measurement of body composition. To the best of our knowledge there are no studies correlating the 6mwd with segmental body composition in severe obesity. Best pract res clin endocrinol metab.

Bmi of 40 or higher. Human body composition measurements are objective methods of nutritional assessment and are of interest to nutritionists health professionals and sports scientists.

Body composition measurement in severe obesity. Curr opin clin nutr metab care 20058602 6. However it is limited to evaluate actual body composition because the values are indirect indices based on body weight height. The aim of this study is to describe the effects of a prolonged dietary behavioral physical activity intervention 24 months on body composition in a group of adolescents with obesity. Body weight and composition were measured at 0 24 and 36 months. Longitudinal study in 196 individuals with obesity 86 boys and 110 girls aged 101149 years that completed a prolonged combined intervention 24 months.
A simple three compartment model combining measurements of body density by air displacement plethysmography and total body water by bio electrical impedance can provide measurements of percentage body fat in the severely obese that are comparable with a traditional highly technical three compartment model requiring facilities such as isotope ratio mass spectrometry along with a substantial technical expertise. Obesity is frequently subdivided into categories.
