United States: A new study found that exposure to toxic PFAS “forever chemicals” during pregnancy has been linked to an increased risk of low birth weight, obesity, and high body mass index (BMI) in children.
The study, which tracked 1,400 children, found that those aged two to five had higher BMIs and a higher incidence of obesity if their mothers were exposed to PFAS during pregnancy. This effect is similar to the impact of prenatal exposure to tobacco.
“Something similar is going on with PFAS,” Mr. Joe Braun, a Brown University researcher and study co-author, stated.
PFAS, which are found in a wide range of products, have been associated with various health problems including cancer, thyroid disease, kidney dysfunction, and birth defects. The chemicals are known as “forever chemicals” as they do not naturally degrade in the environment.
The recent research provides more definitive evidence of the link between PFAS exposure and obesity, as it included a larger sample size and a wider range of exposure levels.
The exact mechanism by which PFAS cause these issues is not yet fully understood, but it is believed that they may affect DNA methylation, a process related to cell production and growth.
The study further suggests that the effects of PFAS exposure can be mitigated through regular exercise. However, reducing exposure to PFAS is challenging, as they are widespread and commonly found in drinking water, indoor dust, and food packaging. Steps to reduce exposure include filtering water, using a vacuum cleaner with a Hepa filter, and consuming fresh, unpackaged foods.
