No results posted yet for this study

Summary

The overall aims of this protocol are to determine whether prenatal supplementation with vitamin C to pregnant smokers can improve pulmonary function and decrease wheeze at 5 years of age in their offspring. This is a continuation of the VCSIP trial, to follow the offspring through 5 years of age. The hypothesis for this protocol is an extension of the VCSIP trial that supplemental vitamin C in pregnant smokers can significantly improve their children's PFTs and decrease the incidence of wheeze.
