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

    This blog ran from 2006 to 2016 and was 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.

    The association between vitamin D and osteoarthritis of the hip

    Researchers from California studied elderly men.

    First, the details.

    • 1,104 elderly men had their 25(OH)D blood levels measured.
    • X-rays of the pelvis were taken about 4.6 years later.
    • Categories of vitamin D levels were as follows.
      • Deficiency: 15 ng/mL or lower
      • Insufficiency: 15.1-30 ng/mL
      • Sufficiency: Greater than 30 ng/mL
    • The findings were adjusted for the effects of age, clinic site, season when blood was withdrawal, self-reported hip pain for greater than 30 days, timed 6-meter walk, at least 1 coexisting condition, and self-rated health status.

    And, the results.

    • Men with radiographic hip osteoarthritis had a significantly slower 6-meter walking time, more hip pain, lower vitamin D level, and a higher prevalence of vitamin D insufficiency and vitamin D deficiency compared to controls.
    • Higher vitamin D levels were associated with a lower prevalence of radiographic hip osteoarthritis after adjusting for age, season, and clinic site.
    • Men with vitamin D insufficiency had an increased likelihood of prevalent x-ray-confirmed hip osteoarthritis compared with men with sufficient vitamin D.

    The bottom line?

    The authors confirmed, “Men with vitamin D deficiencies are twice as likely to have prevalent radiographic hip osteoarthritis.”

    They believe that vitamin D should be taken to augment skeletal health in the elderly.

    Others concur that there is “reasonably strong” evidence that vitamin D reduces the risk of autoimmune diseases including… osteoarthritis.”
