Aim: The aim of our study was to evaluate the inadequacy of voluntary energy and nutrient intake on the first day of hospital admission. Patients and methods: A cross-sectional study was carried out in two terciary care hospitals, with a probabilistic sample of 50% of in-patients. Dietary intake was evaluated by a 24-hour dietary recall, and undernutrition was screened through the Nutritional Risk Screening 2002 tool. The overall frequency of inadequate energy and nutrient intake was estimated using Dietary Reference Intakes. Results: Energy and nutrient intakes from 258 patients showed very low values for both men and women. No significant differences were found for energy and nutrient intakes across age groups (< 65 years and >= 65 years). When the proportion of study subjects with inadequate nutrient intakes was analysed, a high degree of inadequacy was found. The degree of inadequacy was higher for fibre, niacin, folate, vitamin B-12, magnesium and zinc. No significant differences were found for energy and nutrients studied and for intakes below 113 of dietary recommendations from nutritionally-at-risk (n = 89) and well nourished (n = 169) patients. Conclusion: Voluntary nutrient and energy intakes in the first 24 hour of hospital admission are highly inadequate. No differences were found between undernourished and well-nourished patients or patients < 65 years and >= 65 years.
