Sarcopenic obesity and overall mortality: Results from the application of novel models of body composition phenotypes to the National Health and Nutrition Examination Survey 1999–2004
Background/Objectives: There is no consensus on the definition of sarcopenic obesity (SO), resulting in inconsistent associations of SO with mortality risk. We aim to evaluate association of dual energy x-ray absorptiometry (DXA) SO models with mortality risk in a US adult population (≥50 years). Subjects/Methods: The study population consisted of 3577 participants aged 50 years and older from the 1999–2004 National Health and Nutrition and Examination Survey with mortality follow-up data through December 31, 2011.
