Perceptions of Tap Water and School Water Fountains and Association with Intake of Plain Water and Sugar-Sweetened Beverages
A new CDC study published online in the Journal of School Health, found that among youth surveyed, 1 in 5 youth perceive their tap water to be unsafe and nearly 2 in 5 youth consider their school water fountains to be unsafe or unclean. Researchers examined how these perceptions relate to consumption of plain water and sugar-sweetened beverages (SSB) and whether the relationship differs according to race and ethnicity.

Data were collected through the 2010 YouthStyles mail survey. Responses were received from 1,197 participants ages 9-18, yielding a response rate of 49.9%, and also showed the following:
  • There is a high prevalence of low plain water intake among youth. Nearly half of the participants (43.6%) drank plain water twice per day or less often.
  • SSB intake was common. Nearly half, 47.2% of participants drank SSB one time per day or more.
  • Perceived tap water safety concerns were more prevalent among non-Hispanic Blacks (26.4%) and Hispanics (28.3%) compared with non-Hispanic Whites (14.7%) and more prevalent among lower-income youth.
  • Negative water fountain perceptions were more common among high school-aged youth compared to younger youth.
  • Perceived tap water safety concern was not associated with SSB intake or water intake.
  • Negative water fountain perceptions were associated with daily SSB intake only among Hispanics, but were not associated with water intake.
Researchers concluded that a closer look at children's perceptions of both tap water and school water fountains would help to inform school-based and public health efforts to encourage water consumption for youth.
