title: [Malnutrition in old age--results of the Bethany nutrition study].
abstract: One of the nutritional problems in elderly people is undernutrition, which is multifactorial in origin: The causes cannot only be seen in poor nutrition. Physical handicaps such as problems with chewing and swallowing, difficulties to cut food, immobility and mental restrictions are responsible for reduced food intake and malnutrition. Psychic and socio-economic problems such as depression, life events and loneliness may reduce appetite; poverty also contributes to the risk of undernutrition. As a result of our investigations of 300 geriatric patients, physical handicaps with influence on nutrient intake such as immobility or chewing problems were found in nearly 50% of all cases; undernutrition was observed in 22% of the patient group. In a group of 50 apparently healthy women aged 75 or older, the frequency of risk factors as well as the frequency of malnutrition was remarkably lower. These results confirm the thesis that, in most of the cases, undernutrition is related to medical problems and to the simultaneous presence of several of the above-mentioned risk factors. As a conclusion, treatment and prevention of malnutrition have to consider individually the elderly person's complete life situation. Present risk factors have to be removed, if possible; even better would be to avoid them.
