Plastic additives tied to millions of preterm births globally

New York: Exposure to a chemical commonly used to make plastic more flexible may have contributed to about 1.97 million preterm births in 2018 alone, or more than 8 percent of the world’s total, a new analysis of population surveys shows. The chemical was also linked to the deaths of 74,000 newborns, the researchers further estimate. 

The toxin, di-2-ethylhexylphthalate (DEHP), is part of a group of chemicals called phthalates, which appear in cosmetics, detergents, bug repellents, and other household products. Experts have found that these substances can break down into microscopic particles and enter the body through food, air, and dust. 

Led by NYU Langone Health researchers, the new study focused on preterm birth, which is a major risk factor for lasting learning and developmental issues and is a leading cause of infant death, according to the World Health Organization. 

The new analysis published in EBioMedicine provides the first global estimate of preterm births connected to exposure to DEHP and explores which parts of the world are most affected, according to the authors. A report on the findings will be published online March 31 in the journal eClinicalMedicine. 

“By estimating how much phthalate exposure may contribute to preterm birth worldwide, our findings highlight that reducing exposure, especially in vulnerable regions, could help prevent early births and the health problems that often follow,” said study lead author Sara Hyman, MS.
