États des lieux de la supplémentation en vitamine D chez les enfants et adolescents par les médecins généralistes de l'île de La Réunion

Abstract : Background: A universal knowledge: children need vitamin D. Throughout Human History and its discovery, vitamin D is an essential subject because it has and would have many roles in living metabolism. What is sure is that it is useful for bones metabolism and child growth. International European and French recommendations suggest a supplementation throughout growth. Method: Our study shows an inventory of vitamin D supplementation for children and teenagers by general practitioners on Reunion’s Island where sunshine is almost annual. We drove a cross -sectional descriptive study thanks to a survey which was given to fifty doctors practicing on the island. Results: Our results indicate that 70% of general practitioners systematically prescribe vitamin D to children. Most of them recommend supplementation up to 12 or 18 months. Only two doctors advise vitamin D until teenage age. The favoring factors of prescription are skin pigmentation, signs of clinical deficiencies, and sun exposure in an evolution order. 10% of doctors have already prescribed a vitamin D measurement. 20% have already suspected rickets. For 90% of doctors no adverse effects are reported after vitamin D supplementation. And 70% of parents show no reluctance to prescribe vitamin D to their children. But 14% of them describe a difficult deliverance. Most doctors prescribe vitamin D in daily drops to the children. Then, they take it in loading doses with very varied dosages depending on the child. 16% of doctors use Uvedose 100 000 UI every 3 months whatever the season, others prefer its prescription during the austral winter. 78% of general practitioners state that they do not refer to any recommendation leading to a real brake on the vitamin D prescription. The other brakes are the fear of adverse effects like some cases of reported intoxications, the terms of prescription with many uncertainties about dosage and galena. Conclusion: vitamin D supplementation declines with children’s age because of unapproved and unfollowed recommendations. However, we can underline the safety of vitamin D supplementation and its growing interest to children’s and teenagers' health. We offer to encourage its prescription throughout growth to ensure bone capital for adults and for all protective roles confirmed and suspected as in immunology with ongoing and future studies.
