The levels of bisphenol A (BPA) in the urine of premature infants in the neonatal intensive care unit is associated with greater exposure to medical devices, but not with nutritional intake, according to a study published online Feb. 18 in Pediatrics. Susan M. Duty, M.S.N., Sc.D., from Simmons College in Boston, and colleagues measured BPA levels in the urine of 55 premature infants in the neonatal intensive care unit, before and after feeding, and in breast milk or formula from their mothers. The infants’ use of medical devices was also determined.
