Resumen

Background: Handgrip strength is an indicator of frailty in older people. Aim: To determine the prevalence of low handgrip strength in older Chilean adults. Material and methods: A cross-sectional analysis of 244 individuals aged 60 years or more, participating in the 2016-2017 Chilean National Health Survey. Handgrip strength was evaluated by a hand dynamometer and low grip strength was determined as a grip strength ?15 kg and ?27 kg for women and men, respectively. Results: Twenty nine percent of participants had low grip strength. The average grip strength among 60-year-old men and women was 34.7 and 22.1 kg, respectively. These figures decreased to 28.8 kg and 17.2 kg among 90-year-old men and women, respectively. The prevalence of low grip strength in men and women aged 60 years was 18%. In 90-year-old men and women, these figures increased to 79% and 56.3%, respectively. Conclusions: The prevalence of low grip strength increased substantially with age.
