The Official Positions of the International Society for Clinical Densitometry: Body Composition Analysis Reporting

摘要: Dual-energy x-ray absorptiometry (DXA) measurements of body composition increasingly are used in the evaluation clinical disorders, but there has been little guidance on how to effectively report these measures. Uniformity reporting measures will aid diagnosis disorders such as obesity, sarcopenia, and lipodystrophy. At 2013 International Society for Clinical Densitometry Position Development Conference composition, section recommended that all DXA reports should contain parameters mass index, bone mineral density, BMC, total mass, lean fat percent mass. The inclusion additional adiposity optional, including visceral adipose tissue, appendicular android/gynoid ratio, trunk leg index. Within United States, we recommend use National Health Nutrition Examination Survey 1999-2004 dataset an age-, gender-, race-specific reference calibrate BMC 4-compartment models. Z-scores percentiles may be useful interpretation if methods adjust non-normality. In particular, risk-stratification obese sarcopenic patients, needs validation thresholds define obesity sarcopenia. To summarize, guidelines provide evidence-based standards application DXA-based composition.
