Évaluation du statut en vitamine D des patients en court séjour gériatrique à Saint-Paul de la Réunion durant l'hiver austral 2013 et influence des variables démographiques et nutritionnelles

Abstract : Objective: To assess vitamin D status in patients over 70 years admitted in an acute geriatric unit in Saint-Paul, Reunion Island and determine predictive factors for vitamin D deficiency for general practitioners. Materiel and methods: Cross-sectional study in an acute geriatric unit in Saint-Paul, Reunion Island from june to september 2013. 113 patients were included. Several factors were assessed: age, gender, living place, history of fall or fracture, phototype, mobility and laboratory results. Vitamin D status was determined by measuring 25(OH)vit D serum levels. Results: the 25(OH)vit D average level was 24.1 ng/ml. 74% of patients have a vitamin D insifficiency and in 43 % of them the 25(OH)vit D level was lower than 20 ng/ml. The vitamin D serum level was significantly (p=0.02) lower for people living in high altitude (300 meters and more) than those living in the lower part of the island. Conclusion: Despite the high amount of sunshine in Réunion decreased vitamin D serum level was frequent in the studied population. The living place seems to have an impact in the vitamin D status and this could be an interesting element when considering prescribing vitamin D supplementation. Indeed in 2013 the HAS recommend to mesure the 25(oh)vitD serum level only in some cases.
