背景：目前还没有快速筛查老年人总体膳食摄入量的方法。目的：本研究的目的是开发和评估一种饮食筛选工具的评分系统，以识别社区居住的老年人的营养风险。设计：这项横断面研究以居住在农村地区的老年人（n = 204）为研究对象，通过面对面访谈、生化测量和包括膳食补充剂使用在内的4次24小时回忆来检查营养状况。结果：饮食筛查工具能够描述3个水平的营养风险：有风险、可能有风险和无风险。被列为营养风险的个体在饮食质量指标（健康饮食指数和平均充足率）以及蛋白质、大多数微量营养素、膳食纤维、水果和蔬菜的摄入量方面明显较低。高危人群摄入了更多的脂肪、油和精制谷物。高危组的血清维生素B-12、叶酸、-隐黄质、叶黄素和玉米黄质浓度也最低。无营养风险组的番茄红素和β -胡萝卜素含量明显较高，同型半胱氨酸和甲基丙二酸浓度较低。结论：膳食筛查工具是一种简便实用的检测老年人营养风险的工具。[J]中华临床医学杂志，2009;19(3):391 - 391。
Background: No rapid methods exist for screening overall dietary intakes in older adults.Objective: The purpose of this study was to develop and evaluate a scoring system for a diet screening tool to identify nutritional risk in community-dwelling older adults.Design: This cross-sectional study in older adults (n = 204) who reside in rural areas examined nutrition status by using an in-person interview, biochemical measures, and four 24-h recalls that included the use of dietary supplements.Results: The dietary screening tool was able to characterize 3 levels of nutritional risk: at risk, possible risk, and not at risk. Individuals classified as at nutritional risk had significantly lower indicators of diet quality (Healthy Eating Index and Mean Adequacy Ratio) and intakes of protein, most micronutrients, dietary fiber, fruit, and vegetables. The at-risk group had higher intakes of fats and oils and refined grains. The at-risk group also had the lowest serum vitamin B-12, folate, beta-cryptoxanthin, lutein, and zeaxanthin concentrations. The not-at-nutritional-risk group had significantly higher lycopene and beta-carotene and lower homocysteine and methylmalonic acid concentrations.Conclusion: The dietary screening tool is a simple and practical tool that can help to detect nutritional risk in older adults.
