Higher BPA levels linked to more asthma symptoms in children

Children in low-income neighborhoods in Baltimore tended to have more asthma symptoms when levels of the synthetic chemical BPA (Bisphenol A) in their urine were elevated, according to a study from researchers at the Johns Hopkins Bloomberg School of Public Health and School of Medicine.

While some products, including baby bottles, no longer contain BPA, exposures to BPA remain almost universal, and there are still concerns that, especially in childhood, those exposures might have a health impact.

Boys with elevated BPA were found to be at higher risk for having more asthma symptoms, the study found. The researchers found no statistically significant link between BPA levels and asthma symptoms among the girls in the study. The researchers also found that higher levels of two common chemicals closely related to BPA—BPS and BPF—were not consistently associated with more asthma symptoms. Like BPA, BPS and BPF are found in many consumer products, including food cans and beverage bottles.
