The prevalence of malnutrition in institutionalized elderly people is generally high. A good nutritional status is related to a decrease in mortality and costs of morbidity treatments. Therefore, it is essential to know the nutritional status in order to establish action policies. However, there are not enough studies about malnutrition in institutionalized elderly in Spain. ⋯ The prevalence of malnutrition and risk of malnutrition was 40.1%. Female gender and living in institutions located in the main city were identified as malnutrition risk factors. In general, an increase in malnutrition with age was detected, except for people in the last years of their lives. The MNA questions that best predicted the nutritional status were the ones relating to the anthropometrical and self-assessments.
