Complementary and Alternative Medicine: Fair, Balanced, and to the Point
  • About this web log

    This blog is intended as an objective and dispassionate source of information on the latest CAM research. Since my background is in pharmacy and allopathic medicine, I view all CAM as advancing through the development pipeline to eventually become integrated into mainstream medical practice. Some will succeed while others fail. But all are treated fairly here.

    More evidence that vitamin D deficiency makes asthma worse

    Young African-Americans in Washington, DC were studied by researchers at George Washington University School of Medicine and Health Sciences, in Washington, DC.

    First, the details.

    • Total blood levels of 25-hydroxyvitamin D were measured in 113 young African-American residents of Washington, DC.
    • Insufficiency was defined as blood levels less than 30 ng/mL; and deficiency was less than 20 ng/mL.
    • 21 of these people had physician-diagnosed asthma.

    And, the results.

    • The prevalence of vitamin D insufficiency and deficiency was significantly greater among those with asthma vs those without asthma (86% vs 19%).

    The bottom line?

    Most of this sample of urban African-American youth with persistent asthma were vitamin D deficient or insufficient.

    The authors believe that “strong consideration should be given to routine vitamin D testing in urban African-American youth, particularly those with asthma.”

    An earlier study of children living in Costa Rica had similar findings.
