| In a cross-sectional study involving 75 children aged 5 to 11 years of age, with asthma, results indicate a high prevalence of vitamin D insufficiency, which in turn may be associated with asthma control. Only 9.4% of the children showed vitamin D sufficiency (serum 25(OH)D levels 30-40 ng/mL). Additionally, independent significant positive correlations were observed between forced vital capacity percent and the Childhood Asthma Control Test, and serum 25(OH)D levels. Thus, the authors of this study conclude, "Our results indicate that hypovitaminosis D is frequent in children with asthma living in a Mediterranean country. In those children, lower levels of vitamin D are associated with reduced asthma control." | Reference: | "Vitamin D Serum Levels and Markers of Asthma Control in Italian Children," Chinellato I, Boner AL, et al, J Pediatr, 2010 Sep 25; [Epub ahead of print].
