Canadian Study of Health and Aging Selected CSHA Results on Disability Graham et al. (1999) modeled frailty in terms of the more rapid cumulation of functional deficits than normal. Such people are ‘functionally older’ than others. Using this approach, they distinguished normal aging from the effects of diseaseGraham et al. (1999) modeled frailty in terms of the more rapid cumulation of functional deficits than normal. Such people are ‘functionally older’ than others. Using this approach, they distinguished normal aging from the effects of disease Hogan et al. (1999) described changes in function over 5 years. 68% of subjects reported a functional decline; 27% of people remained the same. They described predictors of functional decline, and reported functioning among the very old (85+).Hogan et al.
