RESUMEN
BACKGROUND AND OBJECTIVE: Malnutrition constitutes a serious problem of public health. We intended to know the prevalence of undernourishment in our hospital, as well as to assess the expenses generated by its presence. PATIENTS AND METHOD: A study of cohorts was designed to evaluate the nutritional state of randomly selected patients admitted to a third level hospital. We carried out a protocol of nutritional evaluation and quantified the associated costs including drugs, diet, and hospital stay according to diagnosis-related groups. RESULTS: In agreement with anthropometry and the index of corporal mass, the prevalence of malnutrition was 0.3% and 13.4%, respectively. When analyzing the biochemical markers, the prevalence rose to 65.7%. Patients with malnutrition at the time of admission underwent a 59.9% deterioration of their nutritional state. An increase of costs was observed in relation to the length of hospital stay (68.04% compared with normo-nourished patients). Costs related to consumption of medicines, especially antibiotics, were also higher, as well as costs related to nutritional support. CONCLUSIONS: Malnutrition is a phenomenon frequently observed in a hospital setting. Malnutrition associated costs are significant.

OBJECTIVES: We assessed which factors contribute to the high level of nutritional risk detected by the Mini Nutritional Assessment (MNA) test in institutionalized older women. To this end, we undertook a complete nutritional assessment. METHODS: A cross-sectional study in 89 older women (age range, 72-98 y) living in two private nursing homes in Granada (Spain) was carried out. The MNA test was used as an assessment tool to detect nutritional risk. The nutritional assessment included anthropometric measurements (body mass index, triceps and subscapular skinfold thicknesses, and mid-arm and calf circumferences), quantification of dietary intake (7-d weighed-food records), clinical and functional evaluations (number of drugs, Katz index, and Red Cross cognitive scale), and biological markers (albumin, prealbumin, transferrin, and lymphocyte counts). RESULTS: We found that 7.9% (n = 5) of the older women were malnourished (MNA score, 14.5 +/- 1.4), 61.8% (n = 56) were at risk of malnutrition (MNA score, 20.6 +/- 2.1), and 30.3% (n = 28) were well nourished (MNA score, 25.0 +/- 1.1) according to the MNA test. CONCLUSIONS: This high prevalence of risk of malnutrition detected by the MNA test in healthy institutionalized older women was due mainly to risk situations and self-perception of health and did not depend on age. Inadequate micronutrients intake may contribute to the development of malnutrition in this population.
