Prenatal BPA Exposure Results In Early Childhood Lung Problems
General Information About The Study
The study was conducted to determine if exposing pregnant women to the chemical bisphenol A would result in their children having a higher risk of lung problems. This study was simply looking for a correlation, and no exact mechanism link was studied.
Bisphenol A, or BPA, is a chemical used in plastic, usually clear and hard, and can be found in the lining of metal food containers. This type of plastic is referred to as polycarbonate.
Exactly 398 mother-infant pairs were examined in the study. BPA levels were monitored through urine samples. The women were tested at 16 and 26 weeks of pregnancy.
Also, the children’s level of BPA exposure was measured after birth. Urine samples were collected once every year until the age of 5.
Lung health was examined by measuring the amount of air exhaled at the first second of an exhalation. Whether or not the child developed weezing by age 5 was also noted.
Results of the Study
A tenfold increase in the BPA level in the mothers’ urine corresponded with a fourfold-plus increase in a child’s risk of developing persistant weezing.
A 14.2% decrease in lung function by age 4 occurred in a child for every tenfold increase of average BPA level in a mother’s urine.
Lung function appeared to return to normal at age 5, insinuating that the exposure risks only last for the first few years of life.
No correlation was found in BPA exposure in the first 5 years of life and lung function. Only BPA exposure during pregnancy was found to have an impact.
Conclusion of the Study
Exposure to BPA during pregnancy can raise the risk of negative effects on early childhood lung function, according to the study.
Dr. Adam J. Spanier from the University of Maryland School of Medicine in Baltimore and the study author advises pregnant women to minimize their exposure to BPA.
The Food and Drug Administration (FDA) continues to stand by their standards of BPA in food products and claims that there is no real risk to the public.
