...The syndrome of sarcopenia has become more complex as obesity prevalence has increased to more than 35% in elderly adults.(3) Obesity is associated with medical comorbidity(4) and lower quality of life(5) and can exacerbate agerelated functional decline, leading to disability(6) and institutionalization....

...functional outcomes, and treatment effectiveness and directly affects diagnostic certainty in clinical practice.(12) The purpose of this report is to quantify the magnitude of variation in prevalence rates of sarcopenic obesity using published research criteria consisting of measures that can be practically applied in routine clinical practice....

...The high degree of variation in rates of sarcopenic obesity when using different definitions highlights the need to shift from mathematical distribution-based criteria toward cutoffs related to clinically meaningful outcomes such as impairment of function, mortality, institutionalization, and quality of life.(12) Cross-sectional data demonstrate conflicting relationships between sarcopenia and obesity,(13,14,27) yet existing longitudinal data illustrate the association between sarcopenic obesity and disability(9) and that it may precede impairment in instrumental activities of daily living in community-dwelling individuals and predict functional decline over ensuing years....
