The prevalence of frailty and its associated factors in an Italian institutionalized older population: findings from the cross-sectional Alvise Cornaro Center Study

Background: While it is well established that frail older people have a higher risk of negative health outcomes, the prevalence of frailty and its associated factors in Italian older institutionalized population has never been investigated. Aims: The aims of this study were to assess the prevalence of frailty and to identify its associated factors in an Italian residential care home population. Methods: An observational cross-sectional study was designed to evaluate older people aged 70 or over of an Italian residential care home. A multidimensional assessment examining functional, geriatric, ophthalmic, and audiological domains was carried out to identify factors associated with frailty. Physical frailty was evaluated using Fried’s criteria. Results: Data analysis uncovered a 51.1% prevalence of pre-frailty and a 40.4% prevalence of frailty in the 94 eligible participants (64 females) whose data were complete. The multivariable analysis showed that a low education level (OR = 5.12, 95% CI 1.22–21.49), a low physical quality of life score (OR = 13.25, 95% CI 3.51–50.08), a low mental quality of life score (OR = 9.22, 95% CI 2.38–35.69), visual impairment (OR = 7.65, 95% CI 1.77–33.14), and hearing impairment (OR = 4.62, 95% CI 1.03–20.66) were independently associated with frailty. Conclusions: Frailty was found to be highly prevalent in the residential care home studied. Since frailty is a reversible condition, identifying the modifiable factors associated to it should be viewed as an important step in planning and implementing targeted, early prevention strategies.
