Drink Tap: A Multisector Program to Promote Water Access and Intake in San Francisco Parks.

Taxes on sugar-sweetened beverages (SSBs), or drinks with added sugars, show promise in decreasing purchases and consumption of SSBs. Some have called for coupling such taxes with improvements in access to safe drinking water as a strategy for reducing inequities in SSB intake, yet no studies have examined such an approach. Drink Tap is a San Francisco-based program in which public tap water stations were installed in parks and public spaces (winter 2017) and promotional efforts (fall and winter 2018) encouraged water intake.

Water Security Experiences and Water Intake Among Elementary Students at Low-Income Schools: A Cross-Sectional Study.

Objective: To examine students' experiences of water security at school and how experiences relate to intake of water from different sources of water at school.

Design/methods: In this cross-sectional study, 651 students in grades 3 to 5 in 12 low-income public elementary schools in the San Francisco area completed surveys about their daily intake of water from different sources of water at school, experiences of water security including safety, cleanliness, and taste of water at school, and their demographics. Multivariable linear regressions examined associations between students' water security experiences at school and reported intake from different sources of water at school.
