VCSIP Follow-up Study
NCT ID: NCT03203603 Phase: Status: COMPLETED Enrollment: 242 Completion: 2024-12-31
Conditions
Asthma, Pulmonary Function, Wheezing, In Utero Nicotine
Interventions
No active intervention
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.
Primary Outcome
Improved pulmonary function, spirometry
