The Cognitive-Prefrail Syndrome and Its Association With Adverse Health Outcomes

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.
