The vitamin B6 status of 196 aged subjects living at home and institutionalised in hospital, residential accommodation and sheltered dwelling was studied. Subjects receiving multivitamins were grouped separately and the effect of regular vitamin supplementation on the vitamin B6 status was assessed. The mean dietary intake of vitamin B6 was less than 2 mg/day in all the groups. The biochemical deficiency, as evaluated by erythrocyte glutamic pyruvic transaminase (EGPT) index, was observed in 42.3 per cent of the total subjects; the highest incidence was in subjects of sheltered dwelling. Twenty per cent of the subjects receiving multivitamin also had deficient biochemical levels. Anaemia was noted in 1.3 per cent of the vitamin B6 deficient subjects. Clinical signs of deficiency were noted in one female subject of sheltered dwelling.
对196名居家老人以及住院、居住在养老院和庇护所的老人的维生素B6状况进行了研究。接受多种维生素的受试者单独分组，并评估定期补充维生素对维生素B6状况的影响。所有组中维生素B6的平均膳食摄入量均低于2毫克/天。通过红细胞谷丙转氨酶（EGPT）指数评估，42.3%的受试者存在生化缺乏；庇护所中的受试者发病率最高。接受多种维生素的受试者中有20%的人生化水平也不足。在维生素B6缺乏的受试者中，1.3%的人有贫血症状。在一名居住在庇护所的女性受试者中发现了缺乏的临床体征。
