Abstract

TRONCOSO-PANTOJA, Claudia et al. Prevalence of frailty among Chilean older people. Rev. méd. Chile [online]. 2020, vol.148, n.10, pp.1418-1426. ISSN 0034-9887.  http://dx.doi.org/10.4067/S0034-98872020001001418.

Background:

The assessment of frailty among older people could help to reduce its social and health burden.

Aim:

To determine and characterize the prevalence of frailty in Chilean older adults.

Material and Methods:

We studied 233 participants, aged > 60 years, participating in the Chilean National Health Survey 2016-2017. Frailty was assessed using modified Fried criteria. Thus, people classified as frail should meet at least 3 out of the 5 criteria (low strength, low physical activity, low body mass index, slow walking pace and tiredness).

Results:

The prevalence of frailty was 10.9% (7.7% for men and 14.1% for women). The prevalence of pre-frailty was 59.0% whereas 30.1% of participants were classified as robust. At the age of 80 years 58 and 62% of men and women were frail, respectively. These figures increased to 90 and 87% at the age of 90 years. The prevalence of pre-frailty increased from 43 to 92.1% among men and from 76% and 78% among women from the ages of 60 to 90 years, respectively.

Conclusions:

The prevalence of frailty increased markedly with age. It is important to implement prevention strategies to allow an early identification of high-risk individuals.
