Recent Fast Food Consumption and Bisphenol A and Phthalates Exposures among the U.S. Population in NHANES, 2003-2010.


ABSTRACT:

Background

Phthalates and bisphenol A (BPA) are widely used industrial chemicals that may adversely impact human health. Human exposure is ubiquitous and can occur through diet, including consumption of processed or packaged food.

Objective

To examine associations between recent fast food intake and BPA and urinary metabolites of di(2-ethylhexyl) phthalate (?DEHPm) and diisononyl phthalate (DiNPm) among the U.S.

Population

Methods

We combined data on 8,877 participants from the National Health and Nutrition Examination Survey (NHANES 2003-2010). Using 24-hr dietary recall data, we quantified: a) fast food intake [percent of total energy intake (TEI) from fast food]; b) fast food-derived fat intake (percent of TEI from fat in fast food); and c) fast food intake by food group (dairy, eggs, grains, meat, and other). We examined associations between dietary exposures and urinary chemical concentrations using multivariate linear regression.

Results

We observed evidence of a positive, dose-response relationship between fast food intake and exposure to phthalates (p-trend < 0.0001) but not BPA; participants with high consumption (? 34.9% TEI from fast food) had 23.8% (95% CI: 11.9%, 36.9%) and 39.0% (95% CI: 21.9%, 58.5%) higher levels of ?DEHPm and DiNPm, respectively, than nonconsumers. Fast food-derived fat intake was also positively associated with ?DEHPm and DiNPm (p-trend < 0.0001). After adjusting for other food groups, ?DEHPm was associated with grain and other intake, and DiNPm was associated with meat and grain intake.

Conclusion

Fast food may be a source of exposure to DEHP and DiNP. These results, if confirmed, could inform individual and regulatory exposure reduction strategies.
