摘要
目的:评价我院日常开展的24h膳食回顾在评估住院病人膳食摄入状况的准确性。方法:选取我院40名普通饭住院病人,分别用称重法、24h膳食回顾法对其进行一日膳食调查。将24h膳食回顾法获得的食物消费量和营养素摄入量,与称重法获得的相应数据进行比较,计算两者差值占称重法数据的比例,以此判断24h膳食回顾法数据的准确性。结果:在食物消费量方面,除牛肉和鸡蛋外,其余7种食物的2种方法的差值均有显著差异;但相关分析显示2种方法的数据无相关性。在能量和营养素摄入量方面,2种方法调查结果均有差异;2种方法获得的脂肪、总维生素E、钠、钙和膳食纤维摄入量数据呈一定程度的正相关,能量和其它营养素摄入量则未见相关性。结论:缺少必要辅助工具时,一般专业人员实施的24h膳食回顾调查,往往难以获得良好的质量控制,不能获得理想的评估数据。
