The Nutrition Screening Initiative is a national collaborative effort committed to the identification and treatment of nutritional problems in older persons.
A 14-item checklist of characteristics associated with nutritional status was administered to a random sample of Medicare beneficiaries, aged 70 years and older, in New England. Regression analysis was used to derive item weights that would predict poor nutrient intakes and low perceived health status. Sensitivity and specificity values were reviewed to define low, moderate, and high nutritional risk scores.
A revised checklist containing 10 yes/no items was adopted. Scores of 6 or more points defined persons at high nutritional risk. Twenty-four percent of the Medicare population was estimated to be at high nutritional risk according to the checklist. Among those in the high-risk group, 56% perceived their health to be "fair" or "poor" and 38% had dietary intakes below 75% of the recommended dietary allowances for three or more nutrients.
The Nutrition Screening Initiative Checklist is a brief, easily scored instrument that can accurately identify noninstitutionalized older persons at risk for low nutrient intake and health problems.
营养筛查倡议是一项全国性的合作项目,致力于识别和治疗老年人的营养问题。
对新英格兰地区年龄在70岁及以上的医疗保险受益人的随机样本进行了一项包含14项与营养状况相关特征的清单调查。采用回归分析得出能够预测营养素摄入量低和健康状况感知差的项目权重。审查敏感性和特异性值以定义低、中、高营养风险评分。
采用了一份包含10个是/否项目的修订清单。6分及以上的分数定义为高营养风险人群。根据该清单估计,24%的医疗保险人群处于高营养风险。在高风险组中,56%的人认为自己的健康状况为“一般”或“较差”,38%的人三种或更多营养素的饮食摄入量低于推荐膳食摄入量的75%。
营养筛查倡议清单是一种简短、易于评分的工具,能够准确识别有营养素摄入量低和健康问题风险的非机构化老年人。
