Bisphenol A (BPA) is an endocrine disruptor (ED) frequently used in food packaging. BPA is used as a monomer in the manufacture of some food packaging. This study aimed to evaluate the urinary BPA concentration in an Italian pediatric cohort, testing the levels of this ED over a period of 6 months, evaluating the effects of a diet regimen with a reduction of Plastic Food Packaging (PFP). One hundred thirty Italian children were enrolled and divided into two groups "School Canteen" and "No School Canteen." The first group consumed one meal at school using a plastic-free service for 5 days/weeks, while the other group did not modify their normal meal-time habits. The BPA levels were tested in urine samples at three time points: T0, is the time before the application of the plastic-free regimen diet; T3, 3 months later; and T6, 6 months later. A reduction of urine BPA levels was detected in the "School Canteen" group. In particular, the reduction was significant analyzing both the intra (among the three testing times) group and inter (between "School Canteen" and "No School Canteen") group variability. Our results show the effects of a diet regimen with a reduction of PFP, demonstrating a connection between urinary BPA levels and food packaging.
双酚 A（BPA）是一种常用于食品包装的内分泌干扰物（ED）。BPA 被用作一些食品包装制造中的单体。本研究旨在评估意大利儿科队列的尿 BPA 浓度，在 6 个月的时间内测试这种 ED 的水平，评估减少塑料食品包装（PFP）的饮食方案的影响。130 名意大利儿童被纳入并分为两组“学校食堂”和“无学校食堂”。第一组在学校使用无塑料服务 5 天/周，吃一顿饭，而另一组则不改变其正常的用餐习惯。在三个时间点测试尿液样本中的 BPA 水平：T0，是在应用无塑料饮食方案之前的时间；T3，3 个月后；T6，6 个月后。在“学校食堂”组中检测到尿 BPA 水平降低。特别是，在分析组内（在三个测试时间内）和组间（“学校食堂”和“无学校食堂”之间）变异性时，这种降低具有统计学意义。我们的结果显示了减少 PFP 的饮食方案的效果，证明了尿 BPA 水平与食品包装之间的联系。
