HYPOVITAMINOSIS D

IN CHILDREN IN THE ABSENCE OF SIGNIFICANT CLINICAL SYMPTOMS AND SIGNS

Abstract

Objectives: To determine the frequency of vitamin D deficiency in children under
12 years of age in the absence of significant clinical signs and symptoms in an ambulatory care
settings. Study Design: Descriptive study. Settings and duration: This study was conducted
in Pediatric Out Patient Department of KAUH from June 2013 to June 2014. Materials and
methods: Patients attending the pediatric clinic in KAUH Riyadh, KSA, from June2013 to June
2014, in which 287 healthy children under 12 years were enrolled. Serum calcium, phosphorus,
alkaline phosphatase and 25-hydroxyvitamin D [25(OH) D] were measured .X ray wrists were
taken for radiological evidence of rickets. 25(OH) D levels <50 ng/mL and <25 ng/mL were
defined as insufficiency and severe vitamin D deficiency, respectively. Results: A high prevalence
of vitamin D deficiency is observed in healthy children even in absence of clinical signs and
symptoms. The problem should be highlighted and there is a need to create awareness among
people about the etiology of vitamin D deficiency and its prevention.There is a strong need for
long term planning including populationscreening, dietary supplementation with vitamin D and
food fortification.
