Summary

Lay Summary Older adults who are prefrail (an intermediate, potentially reversible stage between robustness and frailty) with early symptoms of cognitive impairment are a segment of the population that have hitherto remained "silent" and are currently not targets for screening and intervention. These individuals require early identification for preventive interventions to reduce disability, dependency and improve quality of life. To date, there is still no accepted definition of individuals upstream in the spectrum of physical frailty and cognitive impairment. Determining the prevalence and predictive ability of various definitions of co-existent frailty and cognitive impairment could identify older adults at greatest risk of adverse health outcomes. Therefore, the researchers aim to examine and compare (1) the prevalence of cognitive-prefrailty, prefrailty (IANA/IAGG consensus definition) and MCR syndromes, (2) the incidence and predictive ability of these three syndromes for adverse health outcomes including cognitive impairment and decline, dementia, physical functional impairment and decline, falls, hospitalization and mortality in older Quebec community dwellers.

Detailed description

Scientific Summary Background Cognitive frailty is the simultaneous presence of both physical frailty and cognitive impairment, excluding concurrent dementia. This condition confers a greater risk of incident cognitive impairment and decline, dementia, falls and disabilities compared to either condition alone. Current definitions of co-existent frailty and cognitive impairment exist, including the International Academy on Nutrition and Aging (IANA) and the International Association of Gerontology and Geriatrics (IAGG) consensus for cognitive frailty. There is also an analogous construct known as the motoric cognitive risk syndrome (MCR) associating slow gait speed and subjective cognitive impairment (SCI). Current operational criteria identify individuals later in the trajectory of frailty and cognitive decline, which may be too late for effective interventions. The researchers propose to define a new and early condition in the spectrum of Cognitive frailty known as "cognitive-prefrailty", which is a combination of prefrailty stage and SCI. Overall objective This study aims to determine and compare (1) the prevalence of cognitive-prefrailty, cognitive frailty (IANA/IAGG consensus definition) and MCR syndromes, (2) the incidence and predictive ability of these three syndromes for adverse health outcomes including cognitive impairment and decline, dementia, physical functional impairment and decline, falls, hospitalization and mortality in older community dwellers. Methods This study will use the database of the "Nutrition as a determinant of successful aging: The Quebec longitudinal study" (NuAge) study, which is a population-based observational cohort hat recruited healthy community-dwellers with age ranged from 67 to 84 years (51.8% women) between November 2003 and June 2005, and followed them during 4 years. Cognitive-prefrailty, prefrailty and MCR will be defined using information collected at the baseline assessment. Incident adverse health outcomes including cognitive impairment and decline, dementia, physical functional impairment and decline, falls, hospitalization and mortality have been recorded during the 4-years follow-up period. Anticipated results Prefrailty (an intermediate and potentially reversible stage between robust and frailty) and SCI occur upstream in the continuum of frailty and cognitive decline and hence constitute more suitable targets for screening and early intervention in older adults.

Type	Name	Description
OTHER	Data Collection	The NuAge study has been designed to investigate nutrition as a determinant of successful aging in older men and women in Quebec. This study is based on a population-based observational cohort design that initially recruited healthy community-dwellers with age ranged from 67 to 82 years (51.8% women) between January 2004 and April 2005. All participants lived in the areas of Montreal, Laval, and Sherbrooke in the Province of Quebec, Canada. After recruitment, they have been followed for 3 years with one clinical follow-up assessment each year (i.e.; 4 data collection time). A previous analysis performed on the NuAge study database has shown a significant decline of physical and cognitive performances with time (respectively an average of 10% and 2%), participants with lower physical performance showing lower cognitive performance.
