In the elderly, malnutrition is highly prevalent and a major contributor to increased morbidity and mortality. We aimed to evaluate the fat-soluble vitamin status and potential determinants in patients >65 years of age. Serum vitamins A, D and E were determined by liquid chromatography in 166 patients. Gender, age, season, hospitalization, nutritional markers (albumin and cholesterol), acute-phase reactants (ferritin and C-reactive protein) and renal function (creatinine and glomerular filtrate) were assessed as potential determinants. Prevalence of vitamin deficiency was highly variable, ranging from 0 (vitamin E/cholesterol ratio) to 94% (for vitamin D in hospitalized patients). Vitamin status did not differ according to gender, but age, season, hospitalization, a poor nutritional status and impaired renal function, and the presence of acute-phase response significantly affected serum levels of vitamin A, E and D. In conclusion, in subjects >65 years both demographic and clinical factors determined the fat-soluble vitamin status.
