BPA now linked to obesity
September 19, 2012
COMMON plastic bottle and
container ingredient Bisphenol A
(BPA) has been linked to obesity in
children and teens, according to a
new study published in the Journal
of the American Medical Association.
The cross sectional analysis
looked at a subsample of 2,838
American children and teens aged
between six and 19 years, who
were randomly selected for
measurement of urinary BPA
concentration in the 2003-2008
National Health and Nutrition
Examination Surveys.
Of those participants, 1,047 were
classified as overweight and 590
were classified as obese.
According to the study’s findings
the median urinary BPA
concentration was 2.8 ng/mL
(interquartile range, 1.5-5.6).
Children who had the lowest BPA
levels in their urine were found to
have a lower prevalence of obesity.
Researchers also found that
Urinary BPA concentration was
significantly associated with obesity,
but said that explanations of the
association cannot rule out the
possibility that obese children ingest
food with higher BPA content or
have greater adipose stores of BPA.
Interestingly, obesity was not
associated with exposure to other
environmental phenols commonly
used in other consumer products,
such as sunscreens and soaps.
