Multiple Sclerosis Significantly Associated With Vitamin D Deficiency

Vitamin D deficiency represents a significant risk factor for multiple sclerosis (MS), necessitating the need for greater public outreach and interventions to improve vitamin D levels in the population, according to a case-control study published in Neurology.

Investigators performed a prospective nested case-control study using patient data from the Finnish Maternity Cohort, in which approximately 1.8 million serum samples from 800,000 women were recorded. The researchers included 1092 women with MS who had at least 1 serum sample taken prior to their diagnosis. In 511 subjects, ≥2 samples were collected, and 3 controls (n=2123) were used to match each patient according to geographic residence and age.
