We described sociodemographic differences in perceptions of drinking water safety and examined associations between perceptions and plain water intake. We used the 2015 Estilos survey of 1,000 US Hispanic adults conducted in both Spanish and English. Outcome was water intake. Exposures were the level of agreement about water perceptions (My tap water is safe to drink; Community tap water is safe to drink; Bottled water is safer; I would buy less bottled water if my tap water was safe). Covariates were sociodemographics, region, Hispanic heritage, and acculturation. We used chi-square tests and multinomial logistic regression to examine associations of water perceptions and intake. Overall, 24% of Hispanic adults consumed water ≤1 time/day. Although 34% disagreed their home tap water was safe to drink, and 41% disagreed their community tap water was safe to drink, 65% agreed bottled water is safer than tap water, and 69% agreed they would buy less bottled water if they knew their tap water was safe. Perceptions differed by some covariates but were not significantly associated with plain water intake. In conclusion, negative perceptions of tap water were common among US Hispanic adults, which can inform efforts to increase awareness about safe public water systems.

美国西班牙裔成年人对饮用水安全的认识及其与纯水摄入量的关系。

我们描述了饮水安全性认知方面的社会人口统计学差异，并考察了认知与纯水摄入量之间的关联。我们使用了2015年Estilos进行的以西班牙语和英语进行的对1,000名美国西班牙裔成年人的调查。结果是进水。接触程度是关于水感知的共识程度（我的自来水可以安全饮用；社区自来水可以安全饮用；瓶装水更安全；如果我的自来水比较安全，我会少买瓶装水）。协变量是社会人口统计学，地区，西班牙裔遗产和文化适应。我们使用卡方检验和多项式Lo​​gistic回归来检验水感和摄入量之间的关系。总体而言，有24％的西班牙裔成年人每天饮水≤1次。尽管34％的人不同意他们的家庭自来水可以安全饮用，41％的人不同意社区的自来水可以安全饮用，65％的人同意瓶装水比自来水更安全，69％的人同意，如果他们知道自来水是安全的，他们将减少购买瓶装水。知觉之间存在一些协变量，但与饮水量没有显着相关。总之，在美国西班牙裔成年人中，对自来水的负面看法很普遍，这可以有助于人们提高对安全公共水系统的认识。
