ABSTRACT
OBJECTIVES:
Little is known about the severity and long-term health and economic consequences of sarcopenia. We developed a sarcopenia index to measure severity in older Americans and estimated the long-term societal benefits generated by effective interventions to mitigate severity.DESIGN:
Using a micro-simulation model, we quantified the potential societal value generated in the US in 2010-2040 by reductions in sarcopenia severity in older adults. All analyses were performed in Stata and SAS. SETTING ANDPARTICIPANTS:
Secondary data from the National Health and Nutrition Examination Survey (NHANES) (N = 1634) and Health and Retirement Study (HRS) (N = 952) were used to develop a sarcopenia severity index in older adults. MEASUREMENTS Multi-trait multi-method and factor analyses were used to validate and calibrate the sarcopenia severity index, which was modeled as a function of gait speed, walking without an assistive device, and moderate physical activity.RESULTS:
In representative elderly populations, reducing sarcopenia severity by improving gait speed by 0.1 m/s in those with gait speed under 0.8 m/s generated a cumulative benefit of $65B by 2040 (2015 dollars). Improving walking ability in those with walking difficulty generated cumulative social benefit of $787B by 2040.CONCLUSIONS:
Reducing sarcopenia severity would generate significant health and economic benefits to society-almost $800B in the most optimistic scenarios.Palavras-chave
