Recording the nutrient intake of nursing home residents by food weighing method and measuring the physical activity.
The nutrient intake of 47 female nursing home residents, able to eat without help, and of 20 eating-dependent seniors was measured by weighing method. Hand grip strength was examined by a dynamometer. Furthermore the level of physical activity of the seniors able to eat without help was determined by means of a questionnaire. The results showed that the median energy intake of self-feeding elderly women was 1620 kcal (850-4450 kcal). More than one third of the seniors consumed less than 1700 kcal / d. The intake of vitamins and minerals remained below 40-90% of the recommended level. One important cause for the inadequate micronutrient intake was that 30% of the total energy intake is met by foods of a low nutrient density (cakes, cookies, spreadable fats, soups). The eating-dependent seniors were at high risk for protein-calorie malnutrition, consuming an average of 1130 kcal / d and 34 g protein / d. The level of physical activity was very low. Only 34% of the seniors were active for more than 2 hours per week (walking, gymnastics). 30% of the residents were largely inactive although they were able to walk. It is often ignored that immobility is a major risk factor for the development of malnutrition. Firstly inactivity accelerates the loss of muscle mass. This loss of metabolically active tissue decreases the energy requirements thus leading to a loss of appetite and reduced food intake.
