Abstract
The World Health Organization and the European Union highlight the role of nutrition to achieve healthy aging, as well as the need for further research into the impact of social, economic, and environmental determinants on diet. The aim of this study was to identify the factors by assessing their impact on healthy aging by measuring the influence on the main validated nutritional indexes. Factors that impair nutrition status include low socioeconomic status, lack of interest in the usual diet, presence of chronic disabling diseases, consumption of drugs for chronic diseases together with lack of autonomy for daily living activities related to feeding themselves, and needing domestic support services.
