Vitamin D Antenatal Asthma Reduction Trial

A collaboration between Boston University, Brigham & Women's Hospital, Harvard Medical School, Kaiser Permanente Southern California Region, Medical University of South Carolina, Washington University in St. Louis, and the NHLBI

VDAART Background and Purpose

R ecent scientific evidence suggests that a woman's Vitamin D level during pregnancy may be correlated to the development of asthma in her child. Pregnant women who have an elevated risk of having children who will develop asthma are eligible to be enrolled in the VDAART trial. During the course of the study, some will be administered higher doses of Vitamin D for the purpose of determining whether or not it will help prevent or reduce asthma, wheezing, and/or other allergic illnesses in their children. VDAART will also study the role of allergy, the environment, and genetics in the development of asthma.
