Abstract
Background: Persons with severe motor and intellectual disabilities (SMID) have difficulty using general nutritional assessments in the elderly and other populations because of their physical characteristics. The purpose of this study was to investigate the clinical utility of body composition, which has been suggested to be related to biochemical tests in persons with SMID.
Methods: We calculated cutoff values of body composition predicting malnutrition and compared the usage of peripheral parenteral nutrition for the two groups divided by each body composition cutoff value. We also compared body composition at the baseline between nonsurvivors and survivors.
Results: Only group comparisons based on skeletal muscle ratio and extracellular water to total body water (ECW/TBW) cutoffs showed significant differences in the usage of peripheral parenteral nutrition. Nonsurvivors had significantly higher ECW/TBW than survivors at the baseline.
Conclusions: In persons with SMID, skeletal muscle ratio and ECW/TBW measured using multifrequency bioelectrical impedance were associated with biochemical indices and ill health. Furthermore, ECW/TBW was also associated with mortality, suggesting that ECW/TBW is a significant measure for nutritional assessment in clinical practice.
期刊介绍：
The Journal of Intellectual Disability Research is devoted exclusively to the scientific study of intellectual disability and publishes papers reporting original observations in this field. The subject matter is broad and includes, but is not restricted to, findings from biological, educational, genetic, medical, psychiatric, psychological and sociological studies, and ethical, philosophical, and legal contributions that increase knowledge on the treatment and prevention of intellectual disability and of associated impairments and disabilities, and/or inform public policy and practice. Expert reviews on themes in which recent research has produced notable advances will be included. Such reviews will normally be by invitation.
