[Zinc deficiency in geriatric patients. A study on a geriatric department's wheeling and dealing].
We studied the prevalence of zinc deficiency in patients who were hospitalised in a geriatric ward and its association with risk factors for this deficiency and the possible symptoms. The serum zinc level was measured from 45 consecutive admissions to a geriatric ward and patient characteristics were collected. A peer group of healthy subjects originating from a population survey was used as a control group. The serum zinc measured in the admitted patients was significantly lower than the reference value for adults (65.8% had a lowered zinc level) and the serum zinc for healthy elderly. There was no association found with possible causes of zinc deficiency. In an univariate analysis lethargy was the only significant association to zinc deficiency. There was a reverse relationship between the sum of the number of present symptoms and the zinc proportion A lower zinc level is associated with symptoms of zinc deficiency. As more symptoms appear the probability of zinc deficiency is greater. The importance for the clinical practice based on present knowledge is discussed.
