Los investigadores examinaron los casos de hipocalcemia o raquitismo, entre 1996 y 2001, causados por deficiencia de vitamina D. Ésta estuvo definida por niveles de 25-hidroxivitamina D menores de 25 nmol/L. Un total de 65 niños, la mayoría de raza negra o asiáticos, fueron identificados por raquitismo debido a déficit de vitamina D. De ellos, 29 tenían síntomas de hipocalcemia y 48, evidencias radiológicas de raquitismo.
El suplemento de vitamina D consiguió retornar a la normalidad todos los síntomas y signos en todos los niños. Los niños que habían presentado hipocalcemia sintomática eran menores de 3 años o mayores de 10, probablemente porque es en estas edades cuando hay un aumento de la demanda metabólica para el crecimiento rápido. También recomiendan que se considere siempre la deficiencia de vitamina D como la causa más probable de hipocalcemia en estos grupos de población.
