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.

Handgrip Strength Cut-Off Values for the Undernutrition Risk Screening among Elderly Men and Women in Bosnia and Herzegovina

“…High prevalence of risk for undernutrition among elderly in Bosnia and Herzegovina may be attributed to numerous underlying factors. The Community-based Framingham offspring cohort study described the favorable effects of high animal protein intake, but not plant protein on the preservation of HGS [42]. Increased protein intake improved overall protein synthesis and reduced protein breakdown, further leading to the restoring of protein depos and muscle strength [43].…”

A view at sarcopenia by endocrinologist

“…Представленные результаты согласуются с результатами других исследований: например, средняя скорость снижения силы сжатия в исследовании H. Frederiksen и соавт., основанном на анализе трех крупных популяционных исследований, была также выше у мужчин по сравнению с женщинами и составила 0,65±0,02 кг/год, в то время как у женщин -0,34±0,01 кг/год. В исследовании «Возраст и здоровье женщин II» (The Women's Health and Aging Study II) скорость снижения силы сжатия у женщин была в среднем 1,10-1,31 кг в возрасте от 70 до 75 и 0,50-0,39 кг в возрасте старше 75 лет [14].…”
