VCSIP

Vitamin C to Decrease the Effects of Smoking in Pregnancy on Infant Lung Function Trial

A collaboration between Oregon Health & Science University, University of Indiana, PeaceHealth Southwest Medical Center, the National Institutes of Health, and the Office of Dietary Supplements.

VCSIP is studying a possible simple approach to decrease breathing problems in infants born to women who cannot quit smoking during pregnancy. If a woman is unable to quit smoking during pregnancy her infant is more likely to go on to develop increased breathing problems including increased wheezing and respiratory tract infections. There is early information that extra vitamin C taken during pregnancy may help decrease these breathing problems in the infant. Pregnant women who are unable to quit smoking may be eligible to be a part of the VCSIP study. During the study, some women will be given vitamin C (500 mg per day) to determine if it can improve their infant’s lung function and decrease episodes of wheezing through 12 months of age.
