Weakness Status is Differentially Associated with Time to Diabetes in Americans.

Background: The purpose of this study was to evaluate the associations of (1) individual absolute and body size normalized weakness cut-points, and (2) the collective weakness classifications on time to diabetes in Americans.

Methods: We analyzed data from 9577 adults aged at least 50-years from the Health and Retirement Study. Diabetes diagnosis was self-reported.

Prevalence and Trends of Basic Activities of Daily Living Limitations in Middle-Aged and Older Adults in the United States.

Background: Population-level surveillance of the prevalence and trends of basic self-care limitations will help to identify the magnitude of physical disablement in the rapidly growing older American demographic. We sought to evaluate the prevalence and trends of activities of daily living (ADL) limitations in the United States.

Methods: The analytic sample included 30,418 Americans aged ≥50 years from the 2006-2018 waves of the Health and Retirement Study.

The Role of Different Weakness Cut-Points for Future Cognitive Impairment in Older Americans.

Objectives: New absolute and normalized handgrip strength (HGS) cut-points may not yield similar predictive value for cognitive performance. We sought to determine the associations of (1) each absolute and normalized weakness cut-point, and (2) compounding weakness on future cognitive impairment in older Americans.

Design: Longitudinal panel.

The Prevalence and Trends of Instrumental Activities of Daily Living Impairments in the United States from 2008-2018.

Background: Instrumental activities of daily living (IADL) are neuropsychological-driven tasks that are linked to cognitive dysfunction. Examining population-based IADL deficits may reveal insights for the presence of these impairments in the United States.

Objective: This investigation sought to evaluate the prevalence and trends of IADL impairments in Americans.
