BPA Linked to Miscarriage Risk
The chemical compound called bisphenol-A (BPA), which is found in many plastics and food can linings, has been linked to a heightened miscarriage risk in women who struggled to conceive or have experienced repeated miscarriages. The finding comes from a new study presented this week to the American Society for Reproductive Medicine. More from The Associated Press:
The work is not nearly enough to prove a link, but it adds to ‘‘the biological plausibility’’ that BPA might affect fertility and other aspects of health, said Dr. Linda Giudice, a California biochemist who is president of the American Society for Reproductive Medicine. The study was to be presented Monday at the group’s annual conference in Boston. Last month, ASRM and an obstetricians group urged more attention to environmental chemicals and their potential hazards for pregnant women.
BPA, short for bisphenol-A, and certain other environmental chemicals can have very weak, hormone-like effects. Tests show BPA in nearly everyone’s urine, though the chemical has been removed from baby bottles and many reusable drink containers in recent years. The federal Food and Drug Administration says BPA is safe as used now in other food containers.
Most miscarriages are due to egg or chromosome problems, and a study in mice suggested BPA might influence that risk, said Dr. Ruth Lathi, a Stanford University reproductive endocrinologist.
With a federal grant, she and other researchers studied 115 newly pregnant women with a history of infertility or miscarriage; 68 wound up having miscarriages and 47 had live births.
Researchers say it is virtually impossible to avoid exposure to BPA completely. The AP offers some tips on how to minimize exposure:
To minimize BPA exposure, avoid cooking or warming food in plastic because heat helps the chemical leak out, she said. Don’t leave water bottles in the sun, limit use of canned foods and avoid handling cash register receipts, which often are coated with resins that contain BPA.
