Abstract
The aim of this work is to assess level of vitamin D in critically ill
children and to reveal risk factors for its deficiency if present.
Method: Analytic case control study comparing (OH)vit D levels measured
in patients during the hours after critical care admission with the (OH)
vit D levels of healthy children.
Results: Median (OH) vit D level was ng/ml ( - )in pediatric
intensive care unit (PICU) patients vs. ng/ml ( - )in healthy
children (p = ). The prevalence of (OH) vit D deficiency (< ng/ml)
was % and in PICU patients % in healthy children (p = ).
Lack of vitamin D supplementation and sun exposure are strongly related to
vitamin D deficiency. (p value > ). There is negative correlation between
vitamin D and age and weight p value and respectively.
Multivariate logistic regression analysis shows that sun exposure was the only
statistically significant predictor of vitamin D deficiency in the study population
(OR = with P-value < ).
Conclusions: Vitamin D deficiency is common among pediatric patients
admitted to PICU. Lack of sun exposure and lack of vitamin D supplementation
are significant risk factors of vitamin D deficiency in the study population
.Vitamin D deficiency are common in older children. Our study results could be
taken into account for designing interventional studies to study the outcomes of
supplementation.
