Prenatal exposure to ‘forever chemicals’ may raise blood pressure during teen years: Study
- Research released on June 13, 2025, revealed that prenatal exposure to persistent synthetic chemicals, often called "forever chemicals," is linked to higher blood pressure in adolescents, with findings published by the American Heart Association.
- Researchers linked these effects to synthetic PFAS chemicals accumulating in the body and noted stronger associations among boys and non-Hispanic Black children.
- The research examined more than 13,000 blood pressure measurements collected over approximately 12 years from a group of 1,094 participants enrolled in the Boston Birth Cohort, utilizing maternal blood samples obtained shortly after childbirth.
- As PFAS levels doubled, systolic and diastolic blood pressure percentile increases ranged from 1.39 to 2.78, with a 6% to 8% higher elevated blood pressure risk among boys and Black children.
- Researchers called for policy-level changes to reduce PFAS exposure, emphasizing actions on state and federal levels to protect vulnerable populations and future generations.

Development and child health in a world of synthetic chemicals
Chemical pollution is one of today’s most significant threats to the developmental potential of children worldwide. Maternal exposure to toxicants can perturb sensitive windows of fetal development, indirectly through promoting antenatal disorders, abnormal placental adaptation, or directly through maternal-fetal transport. Current evidence clearly shows that persistent organic chemicals promote hypertensive disorders of pregnancy, placental abn…
