Association between beverage intake with urinary bisphenol A levels in Korean women of reproductive age

Abstract

This study was performed to investigate the health effects of exposure to environmental risk factors in Korean women of reproductive age. We analyzed the relationship between daily food intakes and endocrine disrupting chemical such as bisphenol A (BPA). A total of 302 female subjects (30–49 years) participated in this study. Dietary intake was assessed using a single 24 hour dietary recall method. The average daily intake of beverage was 114.2 ± 159.1 g/d and the mean urinary BPA level was 1.7 ± 1.5 μg/g creatinine. The partial correlation adjusted for BMI, total energy intake, cigarette smoking status and education showed that urinary BPA levels was positively correlated with beverage consumption. For this study, soda, canned and sachet coffee, plastic and can packed tea and alcohol were included as beverages. The transfer of BPA into food and beverages from BPA containing packaging materials such as polycarbonate and epoxy resins has been identified by several previous studies as the most likely source of urinary BPA. The study results indicate a leakage of BPA from the polycarbonate and epoxy lining in the plastic or canned containers of beverages, and suggest that increased beverage intake is associated with increased urinary BPA concentration in women of reproductive age.Support or Funding Information[This research was supported by Ministry of the Environment and the Brain Korea 21 Plus.]
