Evaluating the Effects of Supplemental Vitamin C on Infant Lung Function in Pregnant Smoking Women

NCT00632476 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 282

No results posted yet for this study

Summary

Women who smoke during their pregnancy place their unborn child at an increased risk of health problems, including decreased lung function and possible lung diseases later in life. Preliminary animal research suggests that if vitamin C is taken during pregnancy, nicotine's harmful effects on the unborn baby's developing lungs may be blocked. This study will determine the effect that vitamin C has on the lung development and function of babies born to women who smoke during pregnancy.
