Researchers discover that vitamin C improves health for children of pregnant smokers

Researchers have found that vitamin C supplementation to pregnant women unable to quit smoking significantly improves airway function and respiratory health in their offspring at 5 years of age.

While previous studies have shown that vitamin C improves airway function in infants, this is the first study to demonstrate that the improvement in airway function can be maintained through preschool age.

"It's important that we have a way to protect the baby's developing lungs, even if their parent is struggling to quit smoking. These findings have identified an accessible, effective way to ensure optimal respiratory health outcomes both in-utero and throughout a child's young life."

In-utero smoke exposure from maternal smoking during pregnancy can be dangerous for a developing baby and is linked to poor health outcomes, including impaired fetal lung development, decreased airway function and an increased risk for wheezing and asthma. Additionally, decreased airway growth early in life causes increased risk for serious lifelong conditions, such as chronic obstructive pulmonary disease, which is now the third leading cause of death worldwide.

For this study, researchers recruited pregnant women from three sites: OHSU, PeaceHealth Southwest Washington Medical Center and Indiana University. Participating women were enrolled in a double-blind, randomized controlled trial to receive either vitamin C (500 mg/day) or a placebo.

Statistical analyses showed that the effect of vitamin C supplementation to pregnant smokers prior to 23 weeks of gestation consistently resulted in significantly better airway function in their offspring at 5 years old.

While the findings may improve the health of the many children who face in-utero smoke exposure, these findings may have even broader implications: The results may potentially lead to better understanding of—and treatments for—the health impacts of other smoke exposures, including indoor and outdoor air pollution, vaping and wildfires.

Both of my parents smoked.

In my 20s, I got really fit and went to a local university for a VO2 Max test. I performed the exhale two separate times, and the doctor told me I was borderline COPD. I have kept ahead of it, all these years, thankfully.

At least I don’t have asthma.

Read somewhere recently that smokers have an added layer of resistance against covid.
