‘Forever chemicals’ exposure can lead to low birth weight and obesity in later life

Children whose mothers are exposed to toxic PFAS can experience phenomenon previously linked to fetal tobacco smoke exposure

Children whose mothers are exposed to toxic PFAS “forever chemicals” during pregnancy run an increased risk of low birth weight as well as obesity and high body mass index later in life, an effect similar to prenatal exposure to tobacco, new research finds.

The low birth rate effects of some PFAS have been previously established, but the study tracked 1,400 kids and found higher BMIs and more incidences of obesity in those ages two to five. The “low birth weight-high obesity risk paradox” was previously associated with tobacco smoke exposure during fetal development.
