Impact of Estimated Weight and Height on Nutritional Assessment in Elderly
Accuracy of Estimated Weight and Height in Old Inpatients and Their Impact on Nutritional Assessment
Recording the exact weight and height should represent a standard practice for all inpatients, as they significantly impact on patients' care, drug dosing and nutritional assessment.
However, these measurements are recorded in a small percentage of inpatients and, even worse, they often are estimated by nurses or Physicians, or self-reported by patients. This error may contribute to a wrong nutritional assessment, since the body mass index (BMI) is one of the parameters included in some of the most used nutritional scores.
In this study the investigators will perform a nutritional assessement, at hospital admission, in a group of inpatients by the mini-nutritional assessment short form (MNA-SF), by means of estimated, self-reported and exact body weight measures.
Moreover, in those subjects with a malnutrition diagnosis (by MNA-SF) the investigators will perform bioimpedence analysis and will evaluate a series of anthropometric measurements offering insights into body composition and distribution of fat and muscle, such as calf, waist and hip circumference.
