One does not need to live next to a toxic waste dump to be exposed to toxins. Toxins can be found in everyday materials. Bisphenol A (BPA) is found in certain plastics used to make baby bottles, water bottles, and food storage containers. It acts as a hormone, which has called some people to question its safety in consumer products. The European Union and Canada have banned use of BPA in baby bottles.
In the United States, research is showing that BPA may be risky in relation to ADHD in male children. The researchers used 2003-2004 survey data from National Health and Nutrition Examination Survey that showed ADHD could be linked to BPA. Animal studies have showed that BPA may be linked to sex-specific ADHD risk. The most current research, published in June 2016, is in keeping with these findings.
The study showed that of the 460 participants, 8-15 years of age, 7.1 percent met the criteria for ADHD. Children who had above average BPA levels were more likely to have ADHD at 11.2 percent, compared to 2.9 percent for children below the median. That is a pretty striking comparison.
The adjusted odds ratio in BPA concentrations above versus below the median was 5.68. The odds were higher in boys than in girls. The adjusted odds ratio was 10.9 in boys versus 2.8 in girls. These are pretty striking numbers too. However, the meaning is unclear since the sex interaction term was not significant.
BPA is a chemical found in common plastics like those in the water bottle I am drinking right now. One prevention technique is to buy BPA free products. The chemical can seep into food or beverage products that the container holds. Also, if you are concerned about BPA, reduce your use of canned goods. BPA is contained in the resin. Use glass, porcelain, or stainless steel containers instead of plastic.
The Food and Drug Administration says that the amount of BPA in products right now are low enough to be safe. Still, however, France wants to add BPA to the list of substances of very high concern. If this is study is telling us anything, it may be that France is on the right track.
Another study in 2013 showed that boys exposed to BPA levels in children or in the fetus were more likely to experience anxiety, depression, aggression, and hyperactivity at age seven.
