Abstract

Nutritional risk and its predictors were assessed by evaluating longitudinal changes in body weight using data collected from elderly community-dwelling and institutionalized Canadians who participated in both phases of the Canadian Study of Health and Aging, CSHA (n = 10,263). Change in body weight (% initial weight) was examined over a 5-year interval in 584 community and 237 institutionalized participants, and its predictors tested in multiple and logistic regression analyses. Average weight at CSHA-2 was 97% of initial weight at CSHA-1. Values were lower in those over 90 years and the demented. Increasing frailty in a 7-point scale (beta = -1.23, p = 0.04) predicted weight loss in institutional participants, as did difficulty in eating unaided (beta = 4.24, p < 0.001) and reported loss of interest in life (beta = 2.22, p < 0.001) among community subjects. Some 16% in institutions and 9% in the community were at moderate/severe nutritional risk, disproportionately represented by the oldest subjects and the demented. These analyses support the importance of assessing dietary intakes, anthropometrics, well-being and environmental predictors of aging in the elderly.
