OBJECTIVES
The aim of this study was to describe dietary intake and identify predictors of energy and protein intake in a group of high-risk elderly people.
METHODS
All elderly persons receiving publicly financed home care services in the area of Sherbrooke, Quebec, Canada, were eligible. Subjects (n = 145) 60 to 94 years of age from three home care programs were interviewed to measure sociodemographic, health, and food-related behavior variables. Three nonconsecutive 24-hour recalls were used to describe usual dietary intake. Independent predictors of energy and protein intake were derived from multiple regression analyses.
RESULTS
Very low mean energy intakes were observed in this functionally dependent population. More than 50% of the study subjects did not meet the recommended levels of daily protein intake (0.8 g/kg body weight). Significant independent determinants of intake were burden of disease, stress, poor appetite, and vision.
CONCLUSIONS
Results suggest that community-living elderly people with loss of autonomy may have more nutritional problems than healthy elderly individuals. Surveillance of predictors of dietary intake may enable early detection and prevention of nutritional deficits.
目的
本研究旨在描述一组高危老年人的饮食摄入量，并确定能量和蛋白质摄入量的预测因素。
方法
加拿大魁北克省舍布鲁克地区所有接受公共资助家庭护理服务的老年人均符合条件。对来自三个家庭护理项目的145名60至94岁的受试者进行访谈，以测量社会人口学、健康和与食物相关的行为变量。采用三次非连续的24小时膳食回顾来描述通常的饮食摄入量。能量和蛋白质摄入量的独立预测因素来自多元回归分析。
结果
在这个功能依赖的人群中观察到极低的平均能量摄入量。超过50%的研究对象未达到每日蛋白质摄入量的推荐水平（0.8克/千克体重）。摄入量的显著独立决定因素是疾病负担、压力、食欲不佳和视力。
结论
结果表明，失去自主能力的社区居住老年人可能比健康老年人有更多的营养问题。监测饮食摄入量的预测因素可能有助于早期发现和预防营养缺乏。
