Serum levels of carotenoids, zinc and vitamins A, E, C and B2 were measured in al (n = 202) the elderly patients hospitalized in different wards of the hospital studied from February 1986 to October 1988. The study was conducted on 130 men and 72 women with a mean age of 67.8 years (range: 60 to 88 years). The percentage of nutritional deficiency was 59.5% for zinc, 56.5% for vitamin C, 34.5% for vitamin B2, 25.9% for vitamin E, 13.2% for vitamin A, and 6.8% for carotenoids. Elderly patients with leucoses, megaesophagus, chronic obstructive pulmonary disease, and congestive heart failure represent a group with a high prevalence of deficiency both of zinc and of the vitamins under study. These results show the importance of detecting deficiencies of these micronutrients and provide a basis for a more rational approach to the treatment of elderly patients.
1986年2月至1988年10月期间，对在该医院不同病房住院的所有（n = 202）老年患者测定了血清类胡萝卜素、锌以及维生素A、E、C和B2的水平。该研究共纳入130名男性和72名女性，平均年龄为67.8岁（范围：60至88岁）。锌缺乏的比例为59.5%，维生素C缺乏的比例为56.5%，维生素B2缺乏的比例为34.5%，维生素E缺乏的比例为25.9%，维生素A缺乏的比例为13.2%，类胡萝卜素缺乏的比例为6.8%。患有白血病、巨食管、慢性阻塞性肺疾病和充血性心力衰竭的老年患者是锌和所研究维生素缺乏患病率较高的群体。这些结果表明检测这些微量营养素缺乏的重要性，并为更合理地治疗老年患者提供了依据。
