Vit C good for babies born to pregnant smokers

Maternal smoking during pregnancy ad-versely affects the health of newborns in many ways, but taking vitamin C supple-ments may improve lung function and decrease incidence of wheezing in ba-bies born to pregnant smokers, a study showed.Smoking during pregnancy adversely affects lung development, with lifelong decreases in pulmonary (lung) func-tion.“Vitamin C supplementation in preg-nant smokers may be an inexpensive and simple approach (with continued smoking cessation counseling) to de-crease some of the effects of smoking in pregnancy on newborn pulmonary function and ultimately infant res-piratory morbidities,” the researchers noted.At birth, newborn infants born to smokers show decreased pulmonary function test (PFT) results, with res-piratory changes leading to increased hospitalisation for respiratory infec-tions, and increased incidence of child-hood asthma.In a study involving primates, vitamin C blocked some of the in-utero effects of nicotine on lung development and pulmonary function in offspring.For the study, researchers randomly assigned pregnant smokers to receive vitamin C (500 mg/d) or placebo.The researchers found that newborns of women randomised to vitamin C, compared with those randomised to placebo, had improved measures of pulmonary function.Offspring of women randomised to vi-tamin C had significantly decreased wheezing through age one year.“Although smoking cessation is the foremost goal, most pregnant smok-ers continue to smoke, supporting the need for a pharmacologic interven-tion,” the authors noted.Other studies have demonstrated that reduced pulmonary function in off-spring of smokers continues into child-hood and up to age 21 years.The study appeared in the Journal of the American Medical Association (JAMA).
