A variety of endocrine disrupting chemicals (EDCs), including some known to be obesogenic, can be found in household wastewater. Many are only partially treated by wastewater treatment and drinking water purification systems and can enter municipal drinking water supplies. We evaluated drinking water consumption habits in a cohort of obese pediatric patients to determine the percentage that might avoid exposure to EDCs from drinking municipal tap water. Obese (BMI ≥ 95th percentile) children presenting to an obesity clinic serving a largely poor and rural population were studied. Self-reported race/ethnicity, insurance status, and details concerning type and volume of water consumed were obtained from their medical records. Most homes were supplied with municipal, rather than private well water (90.6% vs. 9.4%, respectively). A majority (76.4%) of patients with municipal water as their water supply only drank bottled water. “Taste” and “Health Concerns” were the most commonly endorsed reasons for eschewing tap water. Bottled water consumption among low socioeconomic status patients may reduce their risk for exposure to EDCs in municipal tap water. Further studies are needed to confirm the generalizability of this observation.

开发：感官和感知的健康风险对肥胖，社会经济地位低下的儿科患者的瓶装饮用水和市政自来水消耗的影响

家庭废水中可以发现多种内分泌干扰化学物质（EDC），包括一些已知的致肥胖化学物质。许多废水仅经过废水处理和饮用水净化系统的部分处理，可以进入市政饮用水供应。我们评估了一组肥胖儿科患者的饮水习惯，以确定可以避免饮用市政自来水而暴露于EDC的百分比。研究了就诊于肥胖诊所的肥胖儿童（BMI≥95％），这些儿童主要服务于贫困人口和农村人口。自我报告的种族/民族，保险状况以及有关用水类型和用水量的详细信息可从其医疗记录中获得。大多数房屋都被提供市政水，而不是私人井水（分别为90.6％和9.4％）。多数（76。4％的市政供水患者因为他们的供水仅饮用瓶装水。“口味”和“健康问题”是避免使用自来水的最普遍认可的理由。社会经济地位低的患者的瓶装水消耗量可以降低其暴露于市政自来水中EDC的风险。需要进一步的研究以确认该观察结果的普遍性。
