Finnish Study Links Low Levels of Vitamin D to Higher Risk of MS in Women
Women with low levels of vitamin D in their blood are more likely to develop multiple sclerosis (MS) later in life, finds a large-scale study on women in Finland.
The study, “25-Hydroxyvitamin D deficiency and risk of MS among women in the Finnish Maternity Cohort,” appeared in the journal Neurology.
Several studies have suggested a link between levels of vitamin D, or 25-hydroxyvitamin D (25[OH]D), and MS later in life. However, most of these studies were conducted in small groups and with limited capacity of analyzing vitamin D’s impact on MS.
Hoping to learn more, researchers at Boston’s Harvard T.H. Chan School of Public Health — working with Finland’s University of Turku — analyzed vitamin D levels in more than 800,000 blood samples from pregnant women, as part of prenatal evaluations, and correlated them with the incidence of MS in this population.
