New research shows that the “eternal chemicals” class, the “eternal chemicals” class, the “eternal chemicals” class of industry before it was born into PFAS, could face a rather high blood pressure during adolescence.
The findings raise new concerns about the long-term health risks of prenatal exposure to these persistent contaminants already known to accumulate in the environment and in the human body.
With hypertension in children becoming increasingly common worldwide, scientists say these results highlight the urgent need to address widespread PFA exposure at both individual and policy levels.
What is PFA and why are they dangerous?
PFAS (one person and polyfluoroalkyl substances) are a group of artificial chemicals widely used to withstand water, grease and dirt resistance.
These substances found in non-stick cooking utensils, food packaging, dirt-resistant fabrics, carpets, and even personal care products are forever called chemicals because they do not easily break and accumulate in the environment or in the human body.
Almost everyone around the world is exposed to PFA, with exposure routes such as contaminated food, water, air and skin contact. Of particular concern are the risks during pregnancy. If you develop a fetus, you are extremely vulnerable to toxic contaminants.
Research tracks blood pressure from birth to adolescence
This study was one of the first to examine the time-related effects of prenatal PFA exposure, continuing with a median of 1,094 children from the Boston birth cohort for 12 years.
The researchers analyzed over 13,000 blood pressure measurements collected during routine pediatric visits to understand how early PFA exposure affected cardiovascular development.
The mothers in this study provided blood samples immediately after birth. Researchers found that high concentrations of certain PFAS chemicals are associated with increased blood pressure in adolescents, particularly PFDEA, PFNA, and PFUNA.
When these chemical levels doubled, teenagers showed increased systolic and diastolic blood pressure up to 2.78 and 2.54th percentiles, respectively.
Differences between sex and race
This data revealed a stronger association between PFA exposure and increased blood pressure between boys and children born to non-Hispanic black mothers.
In these groups, the risk of increased blood pressure increased by 6% to 8% with each doubled specific PFA levels.
These findings may reflect broader socioeconomic disparities, including dietary factors and environmental exposure, as well as biological susceptibility.
Although some PFAS compounds were associated with reduced diastolic pressure in early childhood, these associations did not persist in adolescence, suggesting that the long-term effects are more complicated and delayed.
Rising public health concerns
Hypertension in children and adolescents is rising worldwide, increasing the risk of heart disease and stroke.
The findings of this study suggest that prenatal PFA exposure may be a contributor that is often overlooked to this trend, and that it could become an upcoming public health issue.
Unlike many previous studies that stopped following children in early childhood, this study highlights the need to closely monitor health impacts until the teenage years when issues like hypertension may begin to emerge.
What can you do about PFA exposure?
Individuals can reduce PFA exposure by selecting products that do not contain PFAS and using water filters, but experts warn that actual changes must come from policy interventions.
Regulating and eliminating PFA from consumer goods and improving monitoring of water systems is an essential step to reducing widespread exposure.
Public health advocates are seeking better product labeling to help consumers make informed choices, particularly for vulnerable populations such as pregnant women and young children.
This study adds to the increased evidence that PFA exposure has a highly health impact, particularly when contact occurs within the uterus.
With disproportionate cardiovascular risks for boys and children due to disadvantaged backgrounds, environmental justice must play a role in shaping future PFA regulations.
As we become more aware of PFA exposure, the urgency to action will not only protect current generations, but also protect the health of those who have not yet been born.
