Prenatal Exposure to 'Forever Chemicals' Linked to Higher Blood Pressure in Teens
New research reveals that prenatal exposure to synthetic compounds known as 'forever chemicals' is associated with higher blood pressure in children, particularly during adolescence, highlighting the need for policy-level actions to reduce exposure.
Children exposed to synthetic compounds called 'forever chemicals' before birth may face higher blood pressure during their teenage years, according to a new study. The research, published in the Journal of the American Heart Association, found a stronger association among boys and children born to non-Hispanic Black mothers, suggesting these groups may be at increased risk.
Per- and polyfluoroalkyl substances (PFAS), used in products resistant to water, grease, and stains, are nearly ubiquitous in the environment. The study underscores the potential long-term cardiovascular risks posed by prenatal PFAS exposure, emphasizing the importance of reducing such exposure during pregnancy to protect children's health.
The study followed 1,094 children from the Boston Birth Cohort over a median of 12 years, analyzing over 13,000 blood pressure readings. Findings indicated that higher levels of certain PFAS in mothers' blood were linked to increased systolic and diastolic blood pressure percentiles in adolescents. Notably, the risk of elevated blood pressure was 6% to 8% higher for boys and children of non-Hispanic Black mothers with doubled PFAS levels.
Researchers advocate for stronger environmental protections to limit PFAS exposure, particularly during sensitive periods like pregnancy. The study's findings highlight the need for policy-level interventions to phase out PFAS in consumer products and industrial uses, as individual actions alone may not suffice to mitigate exposure risks.
