What will happen if the products we use every day could affect our children’s years before they are even born?
This is the alarming reality revealed in a new study published in Journal of the American Heart Union. The researchers found that children who were exposed to “chemicals forever” before birth were more likely to have higher blood pressure as teenagers. The Association was particularly powerful in boys and children born in non -Spanish -speaking black mothers, raising new concerns about how environmental reports during pregnancy can shape the long -term health of children.
What are chemicals forever?
Typically known as substances and polygamylallis (PFAS), chemicals forever are synthetic compounds used to do water, stains and fat things. They are located in a wide range of everyday products, giggers, microwave popcorn bags, carpets, waterproof jackets, cosmetics and even toys.
It is called “Forever Chemicals” because they do not collapse easily, PFAS are created in our environment and body over time. Studies have shown that it is almost impossible to avoid – most people around the world already have some level PFA in their blood.
This new study was followed by 1,094 children from the Boston Birth Team for up to 18 years. The blood samples taken from their mothers shortly after delivery were tested for eight types of PFAS. The researchers then analyzed more than 13,000 blood pressure readings by children, who were collected during the pediatric routine controls.
Here they found:
- Teen boys and children born to non -Spanish black mothers with high levels of PFAS had significantly higher systolic and diastolic blood pressure between ages of 13 and 18 years.
- When the levels of certain PFAS (such as PFDEA, PFNA and PFUNA) doubled in maternal blood, the risk of increased blood pressure in adolescence increased by 6-8%.
- Interestingly, some pfa appeared to be connected to lower Blood pressure in early childhood – but this effect did not last in teenage years.
Why blood pressure in children matters
High blood pressure during childhood and adolescence can put the stage for heart disease, stroke and other cardiovascular problems later in life. Global studies have shown that child hypertension is becoming more and more common, and this new study suggests that environmental chemicals could be part of the problem – especially for communities already facing health inequalities.
“This study emphasizes how prenatal exposure to PFAS can lead to constant health results that are made clear years after birth,” said Zyu Li, chief author and postgraduate student at Johns Hopkins Bloomberg School of Public Health.
Not equally affected by all children
The findings show that boys and black children were more vulnerable to the harmful effects of exposure to PFAS. While the study is adapted for various social and economic factors, it is clear that both biology and systematic inequalities can play a role.
Dr. Justin Zachariah, a pediatric cardiologist who is not involved in the study, pointed out that exposure to PFAS can come not only from what we buy, but from access to healthier food and cleaner environments. “Packed foods with firmly on shelves-more usual in lower-income households-may contain higher PFAS levels than fresh alternatives,” he explained.
Can families reduce the report?
While it is difficult to completely eliminate PFAS from everyday life, there are a few things that families can do:
- Use a water filter Certified for removing PFAS.
- Choose cookware without pfas, such as iron or stainless steel; and avoid fried pans.
- Limit fast food and microwave popcorn, which often comes in packaging that PFAS processes.
- Control labels About cosmetics and household products for PFAS without certifications.
In addition, researchers warn that significant change should come from the top.
“This is not something people can solve on their own,” said co-author of the study Mingyu Zhang, PhD, from Harvard Medical School. “We need strong policies to gradually abolish PFA in consumer goods and strengthening water safety regulations.”
This study is one of the first to monitor blood pressure from early childhood in adolescence while examining the breed and nationality of the mother. It adds to increasing evidence that prenatal exposure to environmental toxins can have long -term consequences.
“Environmental health is not just here and now,” Dr. Zachariah said. “It is about protecting future generations.”
Snapshot
- Population: 1,094 children from Boston’s birth coach were followed for a 12 -year median.
- PFAs have measured: 8 different types, including PFDEA, PFNA and PFUNA.
- Basic Find: The highest levels of parent PFAS at birth were associated with higher blood pressure in adolescents, especially boys and black children.
- Data source: 13.404 blood pressure readings received during pediatric visits between 2001 and 2024.
- Restrictions: The PFAS report was based on a blood sample collected after delivery. Fewer blood pressure measurements were available during adolescence than in previous years.
This study adds yet another reason to promote the stricter regulation of chemicals forever. While we can make minor changes at home, the biggest solution is to reduce PFAS at the source – before reaching our water, our homes and ultimately to our children.
