Development of reference ranges of handgrip strength among healthy adults 65+ in Northwest Russia: a prospective population-based cohort Crystal study

Abstract

Objectives. This paper sought to provide normative values for grip strength among older adults 65+ across different age groups in northwest Russia. Methods. A population-based prospective cohort study of 611 community-dwelling individuals 65+. Grip strength was measured using the standard protocol applied in the Groningen Elderly Tests. The cut-off thresholds for grip strength were defined separately for men and women of different ages using a weighted polynomial regression. Results and conclusions. 1. This study presents age- and sex-specific reference values for grip strength in the 65+ Russian population derived from a prospective cohort study. 2. The grip strength values obtained in the current study were lower than those reported in other population-based studies in Europe and USA.
