Recently, the American NCHS published national estimates of muscle strength in older adults in the United States in 2011-2012, based on maximum hand grip strength. Weak muscle strength is clinically relevant, because of its associations with mobility impairment. The report shows that 5% of adults aged 60 and over had weak muscle strength, 13% had intermediate muscle strength, while 82% had normal muscle strength. The prevalence of reduced (weak and intermediate) muscle strength increased with age, while the prevalence of normal strength decreased with age. Muscle strength status did not differ by sex, except among persons aged 80 and over, where women had a higher prevalence of weak muscle strength than men. Non-Hispanic Asian and Hispanic persons had a higher prevalence of reduced muscle strength than non-Hispanic white persons.
