Urinary bisphenol a concentrations in children with attention-deficit/hyperactivity disorder: a pilot study

Background: Bisphenol A (BPA) is an industrial chemical associated with several health effects and exposure to BPA remains poorly characterized in the developing countries. In this pilot study, we evaluated BPA exposure, assessed some sources of exposure and its health effects among Egyptian children. Methods: Total BPA concentration was measured in two groups of spot urinary samples of ADHD (N = 24) and apparently healthy control (N = 24) children. Questionnaire data regarding food storage behaviors to assess potential sources of exposure was collected. Results: ADHD children exhibited higher urinary BPA concentrations; with median value of 24.5 μg/L. Reported consumption of canned food was a significant predictor of increasing concentrations of urinary BPA. Conclusion: The reported relatively high urinary BPA concentrations within Egyptian children with ADHD and the significant association between the canned food consumption and the increased urinary BPA concentration highlights the need to modify food and consumer product patterns to prevent potential adverse health outcomes in the future.
