    Abstract:
    This study was aimed at evaluating the correlation between bone mineral density (BMD) and the psychophysical health status in an elderly study population (62 subjects, mean age 84+/-5 years, 21 males and 41 females), institutionalized (Group A) in various structures of Pozzallo, a marine locality of the Ragusa Province in Sicily. BMD was measured by using ultrasonography of the calcanear area (T-score, Z-score, stiffness). The alterations of the cognitive and affective spheres as well as the levels of autonomy and autosufficiency were estimated by means of psychometric scales like mini-mental state examination (MMSE), geriatric depression scale (GDS), activities of daily living (ADL) and instrumental activities of daily living (IADL). Other biological, social and health-related factors, such as age, sex, body weight and height, nutritional and drug-taking habits, physical activity and previous pathologies, were also considered. These variables were compared to those obtained in a similar, but non-institutionalized controls (Group B) of 63 subjects (mean age 85+/-2 years, 27 males and 36 females), being similar in number and age distribution, frequenting the Geriatric Day Center of the same locality. Statistical analysis revealed significant differences between Groups A and B: the BMD was considerably lower, but also the cognitive and affective performances were strongly reduced in Group A. These findings can be attributed to decreased psychosensorial stimuli and lost interest of the patients in Group A, resulting in a lower physical activity, accompanying the depressive state, and may represent the first signs of a decreased intellectual performance, which can later be transformed into dementia. The functional abilities and the levels of autonomy are also reduced, risking the loss of autosufficiency. Also, the drug usage was different in Group A: more sedative-hypnotics and anticoagulants were consumed. As regards the polymorbidities, arterial hypertension and consequent chronic renal failure, hepatopathies and thyreopathies were most frequent, these latter two being more frequent in the Group A.
