More bad health news for BPA
, as two new studies have recently been released linking the chemical -- commonly found in plastic food packaging -- to childhood obesity and asthma.
The first study, conducted by researchers at the University of Michigan, found that kids who are exposed to higher levels of BPA were more likely to be obese, and tended to have a higher waist circumference-to-height ratio, than those with the lower exposure levels.
Researchers used nutrition survey data from 6 to 18 year olds collected through 2010. They compared the BPA levels found in the kids of various ages with other health measures and found that compared to kids with the lowest BPA levels, the 25 percent with the highest levels were twice as likely to be considered obese based on weight and growth charts.
The second study, conducted by researchers at the University of California, Davis, looked at the fetal lung development in monkeys whose mothers were exposed to BPA while pregnant. Researchers exposed the pregnant monkeys to the same level of BPA commonly found in human blood. They found that the BPA exposure caused fetal lung changes consistent with the future development of asthma.
It's a preliminary study for sure, but it's also interesting because it's one of the first to look at the effects that BPA can have on the respiratory system. Lots of studies have linked BPA to other health concerns, such as obesity
, behavioral issues
, reproductive problems
, and even tooth decay
. But this is one of the first to link BPA to asthma.
