Abstract :
anorexia is the most frequent modification of eating habits in old age, which may lead to
malnutrition and consequent morbidity and mortality in older adults. We aimed to estimate the prevalence and
factors associated to anorexia in a sample of italian older persons living in different settings. our secondary aim
was to evaluate the impact of senile anorexia on nutritional status and on eating habits, as well as on functional
status. Design and Setting: observational study in nursing homes, in rehabilitation and acute geriatric wards, and
in the community in four italian regions (Lazio, Sicily, emilia-romagna, and veneto). Participants: 526 over 65
years old participants were recruited; 218 free-living subjects, 213 from nursing homes, and 96 patients from
rehabilitation and acute geriatric wards in the context of a national research Project (Prin) from the italian
Ministry of instruction, university and research (2005-067913 “Cause e Prevalenza dell’anoressia senile”).
Measurements: anthropometric and nutritional evaluation, olfactory, chewing, and swallowing capacity, food
preferences, cognitive function, functional status, depression, quality of life, social aspects, prescribed drugs, and
evaluation of gastrointestinal symptoms and pain. Laboratory parameters included prealbumin, albumin,
transferrin, C-reactive protein, mucoprotein, lymphocyte count, as well as neurotransmitters leptin, and ghrelin.
anorexia was considered as ≥50% reduction in food intake vs. a standard meal (using 3-day "Club Francophone
de gériatrie et nutrition" form), in absence of oral disorders preventing mastication. Results: the overall
prevalence of anorexia was 21.2% with higher values among hospitalized patients (34.1% women and 27.2%
men in long-term facilities; 33.3% women and 26.7% men in rehabilitation and geriatric wards; 3.3% women and
11.3% men living in the community) and in the oldest persons. anorexic subjects were significantly less selfsufficient
and presented more often a compromised nutritional and cognitive status. Diet composition analyses of
anorexic older adults revealed a lower intake of all food groups and a general tendency to a monotonous diet.
Conclusion: anorexia is a frequent condition in older italians, particularly those hospitalized, with important
consequences in the nutritional and functional status. the analysis of dietary components and its quality along
with the frequency of intake of single food groups may be useful to plan intervention strategies aiming to
improve the nutritional and health status of older adults with anorexia. an early detection of anorexia followed
by an adequate intervention in older hospitalized patients to avoid further worsening of clinical and functional
status is warranted.
