Balance performance and grip strength as predictors of cognitive function among community-dwelling older adults in the USA.

Objectives: To investigate how balance and grip strength predicts the probability of cognitive function impairment (i.e., executive function: mild and mild-to-moderate impairment, and delayed recall) over eight years in community-dwelling older adults in the US, controlling for sex and race/ethnicity.

Short Physical Performance Battery and Mediation of the Effect of Mild Cognitive Impairment on Falls by Community-Dwelling Older Adults.

Objective: The authors examined the association among cognitive function, falling, and physical performance among community-dwelling older adults (ages ≥65 years).

Methods: Eight waves of the National Health and Aging Trends Study (NHATS; 2011-2018) were assessed, with 1,225 respondents who participated in all waves. The outcomes were self-reported number of falls and NHATS Short Physical Performance Battery (SPPB) score.
