Reduced appetite. A predictor for undernutrition in aged people
1Dept. of Medicine, Aker University Hospital, Oslo, Norway. morten.mowe@os.telia.no
Background:
Malnutrition is a common condition among aged, hospitalised patients, which may be due to lack of appetite in the same group. It is uncertain, however, the relationship between a reduced appetite and the nutritional status.
Objective:
Assess the prevalence of reduced appetite, and to study the relationship between a reduced appetite and the nutritional status.
Design:
A randomised population survey among elderly: one group recruited from patients recently admitted for acute disease or exacerbation of disease, and one group recruited from their homes.
Results:
Reduced appetite was present in 43% in the hospital group, compared to 15% in the home living group. Seventy-one % of those with reduced appetite were undernourished, while 44% with normal appetite were undernourished. The sensitivity for malnutrition was 0.55, while the positive predictive value was 0.71.
Conclusion:
Reduced appetite is common among aged people in hospital, and is a predictor for undernutrition.
