Nutritional risk in vulnerable community-living seniors

摘要

The purpose of this study was to quantify nutritional risk in a convenience sample of vulnerable, community-living seniors, and to determine patterns of nutritional risk in these seniors. The sample consisted of 367 seniors who provided health, functional, and nutritional risk information during an interview in which the Seniors in the Community: Risk Evaluation for Eating and Nutrition questionnaire was used. The majority (73.6%) of the sample was female, and the mean age was 79 years. Nutritional risk was identified in 68.7% of the sample, with 44.4% being at high nutritional risk. Common nutritional risk factors were weight change, restricting food, low fruit and vegetable intake, difficulty with chewing, cooking, or shopping, and poor appetite. Principal components analysis identified four independent components within the Seniors in the Community: Risk Evaluation for Eating and Nutrition questionnaire; these components can be descnibed as low food intake, poor appetite, physical and external challenges, and instrumental activity challenges. Data are sparse on nutritional risk in community-living Canadian seniors; despite methodologic limitations in the recruitment process, this study provides some indication of the level of nutrition problems. The patterns of nutritional risk identified in this vulnerable population may help providers identify useful strategies for ameliorating risk. The Seniors in the Community: Risk Evaluation for Eating and Nutrition questionnaire could be used to identify risk and patterns of risk in Canadian seniors, so that treatment could be individualized.
