[Anemia and functional incapacity at admission to a geriatric home].

AIM: To ascertain the prevalence of anemia on admission to a nursing home, and to assess the relationship between the observed cases of anemia and the functional status of those subjects. METHODS: We studied 198 subjects: 82 men (41%) aged 75.8 +/- 8.8 years, and 116 women (59%) aged 78.2 +/- 8.3 years. Anemia was diagnosed according to the criteria of the World Health Organization. The classification as non-disabled, or physically or mentally disabled, was done according to the Scales of the Spanish Red Cross. RESULTS: Anemia was diagnosed in 36% of the males, being microcytic in 14%, normocytic in 83%, and macrocytic only in 3% of them. Among women there were 44% with anemia, which was microcytic in 16%, normocytic in 80%, and macrocytic in 4% of cases. The prevalence of anemia increased with age in both sexes. Among men, anemia was significantly associated (p = 0.013) with physical disability, whereas among women this association just fell off significance (p = 0.06). There was no association of anemia with mental disability. No association was found between serum concentrations of ferritin, vitamin B12, or folic acid, and the classification as non-disabled, or as physically or mentally disabled. CONCLUSIONS: Anemia is found in about 40% of the elderly on admission to our nursing home. Anemia is associated with older age and with physical disability, but not with mental disability. Whether anemia on admission entails a higher risk of disability onset during the stay in the nursing home remains to be elucidated.

[Thyroid function in the aged admitted to a nursing home].

BACKGROUND: Intrinsic thyroid diseases and so-called sick euthyroid syndrome are frequent among the elderly. Therefore, we set out to assess the usefulness of the measurement of thyroid hormones and TSH on admission to a public nursing home. METHODS: A medical history, physical examination, geriatric assessment and a venous sample were taken from 201 elderly subjects on admission to a nursing home. Thyroid hormones and TSH were measured in all cases. All subjects were classified as valid, mentally impaired, or physically impaired, according to the Spanish Red Cross Scales. RESULTS: Sixty non-disabled and 141 disabled elders were studied. Sixteen (7.9%) cases of primary hypothyroidism were found, of whom 7 (3.5%) were deemed deserving treatment with L-thyroxine, their mean daily dose being 114.3 mcg. Sick euthyroid syndrome was considered to be present in 28 (13.9%) cases, of whom 25 had a normal T4, three had a low T4, and none had a high T4. No cases of hyperthyroidism were detected. Thyroid hormone abnormalities were not statistically associated with age, gender, or physical or mental disability. CONCLUSIONS: On admission to the nursing home, nearly 8% of the elders have hypothyroidism, and an additional 14% have the sick euthyroid syndrome. Routine measurement of T4 and TSH in elders on admission to a nursing home has a favorable cost-utility ratio.

[Healthy aging and functional disability among the elderly inhabitants of the Canary Islands (Spain)].

BACKGROUND: Among the elderly, health is usually measured in terms of ability for both the Basic and Instrumental Activities of Daily Living. The objective of this work is to estimate the percentage of healthy elderly among the population of the Canary Islands (Spain) and the factors associated with functional disability in this older population. METHODS: We randomly sampled 411 elderly from the whole population of the Canary Islands, of whom 97 had died or could not be located. Of the 314 people approached, 29 (9.2%) denied participation. The 285 participants were interviewed with the Spanish version of Pfeiffer's Functional Assessment Inventory previously adapted and validated in our habitat. RESULTS: Up to 53% of the elderly (61% of males and 47% of females) were disability-free. Greater disability was associated with higher age, lesser education, worse subjective health, worse subjective vision, and worse subjective hearing. No association of disability with female gender and cognitive deficit was found when including age and education in the logistic model. CONCLUSIONS: Health status among the elderly in the Canaries is similar to that in developed countries. In contrast with other studies, we found functional ability associated with poor hearing and dissociated from cognitive deficit.
