Prevalence and factors associated with frailty in longevous elderly: an systematic review

Frailty is a biological syndrome characterized by a number of age-related clinical conditions. The prevalence of specific frailty among the longevous population remains poorly investigated. In this context, the present study aimed to identify, through an systematicliterature review, the prevalence and factors associated with frailty in longevous elderly. This is a bibliographic study,systematicliterature review type, of studies published in Portuguese, English and Spanish, through the PICO strategy, in four databases, MEDLINE/PUBMED, Scielo, Ebsco and Science Direct conducted from April to May 2022. The selection resulted in three studies, two cross-sectional studies and one prospective cohort study. The prevalence of frailty among the longevous elderly ranged from 12.4% to 64.7%. As for associated factors, the studies showed associations between frailty and gender, increasing age, hospitalization in the past 12 months, residence in a long-stay institution, chronic conditions, dyslipidemias, metabolic diseases, depression, dementia, visual and hearing impairments, disability for ≥ 2 activities of daily living, and falls.
