Evidence swells linking vitamin D to arthritis risk

Vitamin D deficiency may be linked to inflammatory rheumatic disease, suggests new research.

New research supports further links between vitamin D levels and risk of developing a chronic inflammatory rheumatic disease, like arthritis.

About one of every five American adults has doctor-diagnosed arthritis, according to the Centers for Disease Control.

Previous research analyzing data from over 29,000 women over 11 years suggested that women with lower levels of vitamin D were more likely to develop rheumatoid arthritis. In the new study, Spanish researched compared 677 control subjects to 721 patients with psoriatic arthritis, 775 patients with rheumatoid arthritic and 738 people with ankylosing spondylitis, a type of arthritis of the spine. They found vitamin D deficiencies in about 27 percent of the control subjects, 41 percent of the psoriatic arthritis patients, 40 percent of the rheumatoid arthritis patients and 40 percent of the ankylosing spondylitis patients.

Physicians should monitor the vitamin D levels of arthritis patients and supplement if deficiency is detected, concluded the study’s authors. The research was published in the journal Arthritis Research and Therapy and noted on MD Magazine.

Other recent research linked vitamin D to brain health. Researchers in China conducting a meta-analysis discovered an increased risk of Alzheimer’s disease and dementia among people with vitamin D deficiencies.
