The aim of this study was to examine possible causes of malnutrition i
n geriatric patients on admission to hospital by evaluation and compar
ison of their meal pattern between periods of working, retirement and
hospitalization, respectively. Forty-five consecutive patients aged 60
years or older participated. By use of modified dietary history inter
views, a retrospective assessment of food intake was carried out. A qu
alitative system for meal classification was then applied. In the reti
rement period there was a strong reduction in daily eating frequency w
hen compared to working and hospital periods. Thus, the daily intake a
nd also distribution of energy and nutrients seem to be reduced during
retirement, which might lead to nutritional deficiency.
