Pregnancy Exposure to “Forever Chemicals” May Fuel Childhood Obesity — A federally funded study |
A new study from Brown University reveals that prenatal exposure to “forever chemicals” is linked to higher body mass indices and increased obesity risk in children, emphasizing the need for ongoing research and policy adjustments to mitigate exposure risks.
According to CDC statistics on childhood obesity in the United States, for children and adolescents aged 2-19 years in 2017-2020, the prevalence of of obesity was 19.7% and affected about 14.7 million children and adolescents. Thousands of individual PFAS are used in oil- and water-repellant textiles, personal care products, firefighting foams, food packaging, medical products and many other household products. Toxic PFAS are incredibly durable and are thought to persist in the environment for thousands of years, which is how they’ve come to be known as “forever chemicals.”
These associations were observed even at low levels of PFAS exposure, said senior author Joseph Braun, a professor of epidemiology and director of the Center for Children’s Environmental Health at Brown’s School of Public Health. This is important to note, Braun said, since PFAS exposures have changed over time as some manufacturers have voluntarily phased out their use in response to concerns of associated health effects as well as environmental persistence.

Vaccine against deadly chytrid fungus primes frog microbiome for future exposureA human or animal's microbiome—the collection of often beneficial microorganisms, including as bacteria and fungi, that live on or within a host organism—can play an important role in the host's overall immune response, but it is unclear how vaccines against harmful pathogens impact the microbiome. A new study led by researchers at Penn State found that a new vaccine against the deadly chytrid fungus in frogs can shift the composition of the microbiome, making frogs more resilient to future exposure to the fungus.
