AIM
To predict malnutrition risk of older residents by cognitive function, nurse support and self-care capacity as primary measures of interest.
DESIGN
Cross-sectional, correlation design with linear regression analysis.
METHODS
Older residents over 60 years of age were randomly selected from nursing homes. Mini Mental State Exam and the Mini Nutritional Assessment were used were as main measures.
RESULTS
Lower malnutrition risk was associated with better cognitive functioning. Improved independence of self-feeding was also linked to reduced nutritional risk. Nurse support was positively related to BMI and cognitive impairment. General self-care capacity and 'appetite the week before' were key predictors of malnutrition risk; 1-point increase in both variables caused nutritional risk to decrease by 1.73 and 1.38 points, respectively. That is, a 1-point increase in self-care capacity and appetite would decrease malnutrition risk by 5.76% and 4.6%. The regression model explained significant amount (65.6%) of variance in malnutrition risk.
目的
以认知功能、护士支持和自我护理能力作为主要关注指标，预测老年居民的营养不良风险。
设计
采用横断面相关性设计并进行线性回归分析。
方法
从养老院中随机选取60岁以上的老年居民。使用简易精神状态检查表和微型营养评定量表作为主要测量工具。
结果
较低的营养不良风险与较好的认知功能相关。自我进食独立性的提高也与营养风险降低有关。护士支持与体重指数和认知障碍呈正相关。总体自我护理能力和“前一周食欲”是营养不良风险的关键预测指标；这两个变量每增加1分，营养风险分别降低1.73分和1.38分。也就是说，自我护理能力和食欲每增加1分，营养不良风险将分别降低5.76%和4.6%。回归模型解释了营养不良风险中显著比例（65.6%）的方差。
