BPA chemical ban in the USA takes effect 1st October 2011.

Finally a law banning the use of BPA takes effect from 1st October 2011 across the United States. This law is the first of its kind in the nation to ban products containing bisphenol A. Kudos to the advocates of BPA ban!
The law ban use of the chemical in reusable food and beverage containers, reusable spill-proof cups, containers of infant formula and baby food, plastic sports bottles, and Thermoses.
This ban is as a result of increase evidence on the harmful effects of this chemical especially its endocrine disrupting effects commonest amongst which is type 2 Diabetes Mellitus.
I hope a global ban on the manufacture and use of BPA would soon be in place. This will surely help avoid the world advanced economies from further manufacturing of the chemical (for their economic gains) and subsequent dumping of it on the developing nations. I equally pray that the world industrialised nations would transfer their technological knowledge on the alternative to BPA (which I believe is in place in their countries) to enable the low and mid-income economies adopt it.

A new study on Bisphenol A and Diabetes!

There is no doubt that the introduction of BPA in our packages have greatly transformed the food industry…..thanks to globalisation.
It is my believe that this transformation has come but with a ‘price tag’ attached to it…………..the increase in the number of type 2 diabetes across the globe within the past 10 years may not be unconnected to the increase use of BPA.
I came across this latest study (ahead of print) on BPA and diabetes (refer to my earlier blog post on BPA and Endocrine disruptors), [J Clin Endocrinol Metab. 2011 Sep 28. Relationship between Urinary Bisphenol A Levels and Diabetes Mellitus. Shankar A, Teppala S.] using NHANES.
This latest study looked at 2003-2008, and has the highest OR while the previous studies on BPA and diabetes have looked at years 2003-4 (positive association; OR 1.39) and 2005-6 (no association) and pooled 2003-6 (positive association; OR 1.24).
The Abstract reads as follows:
Background: Bisphenol A (BPA) is a widely used chemical in the manufacture of polycarbonate plastics and epoxy resins. Recent animal studies have suggested that BPA exposure may have a role in the development of weight gain, insulin resistance, pancreatic endocrine dysfunction, thyroid hormone disruption, and several other mechanisms involved in the development of diabetes. However, few human studies have examined the association between markers of BPA exposure and diabetes mellitus.
Methods: We examined the association between urinary BPA levels and diabetes mellitus in the National Health and Nutritional Examination Survey (NHANES) 2003-2008. Urinary BPA levels were examined in quartiles. The main outcome of interest was diabetes mellitus defined according the latest American Diabetes Association guidelines.
Results: Overall, we observed a positive association between increasing levels of urinary BPA and diabetes mellitus, independent of confounding factors such as age, gender, race/ethnicity, body mass index, and serum cholesterol levels. Compared to quartile 1 (referent), the multivariate-adjusted odds ratio (95% confidence interval) of diabetes associated with quartile 4 was 1.50 (1.05-2.14) (p-trend = 0.03). The association was present among normal-weight as well as overweight and obese subjects.
Conclusions: Urinary BPA levels are found to be associated with diabetes mellitus independent of traditional diabetes risk factors. Future prospective studies are needed to confirm or disprove this finding.
