We studied the riboflavin intake and biochemical status in a representative sample (20 males and 52 females) of institutionalized elderly people (aged 68-95) living in the Autonomic Community of Madrid. The riboflavin density of the diet was in general higher than the recommended amount, so the quality of the diet, related to riboflavin, can be considered satisfactory, and probably the caloric deficit is the major cause of the low intakes found. We found no correlation between the intake and biochemical status of riboflavin. The elderly with erythrocyte glutathione reductase greater than 1.2 are not those who have lower intakes. The cause of the deficit could be the different malabsorption problems and diseases that affect people as age increases.
我们对居住在马德里自治区的机构养老老年人（年龄在68 - 95岁）的一个代表性样本（20名男性和52名女性）的核黄素摄入量和生化状况进行了研究。饮食中的核黄素密度总体上高于推荐量，因此与核黄素相关的饮食质量可被认为是令人满意的，热量不足可能是所发现的摄入量低的主要原因。我们发现核黄素的摄入量与生化状况之间没有相关性。红细胞谷胱甘肽还原酶大于1.2的老年人并非摄入量较低的人群。随着年龄增长，影响人们的不同吸收不良问题和疾病可能是缺乏核黄素的原因。
