Schools are a key setting for curbing student intake of sugar-sweetened beverages (SSBs). While studies suggest that restrictions on SSBs, increased access to healthier beverages, and education about the importance of drinking water instead of SSBs can promote healthier beverage patterns among students, there is little known about the impact that teachers' own beverage choices can have on those of their students. Data were drawn from cross-sectional surveys administered as part of a larger evaluation of a drinking water access and promotion intervention in public elementary schools in the San Francisco Bay Area region of California. Descriptive statistics were used to examine teacher (n = 56) and student (n = 1176) self-reported beverage consumption at school. Mixed-effects logistic regression was used to examine associations between teacher and student beverage intake adjusting for clustering of students by teacher. Teachers were also surveyed via open-ended questions about strategies to increase student water consumption at school. Nearly all teachers reported drinking water during the school day (95%), often in front of students. Teacher SSB intake was rare (9%). Students whose teachers drank water in front of their classes were significantly more likely to report drinking water during the school day. Teachers tend to select healthy beverages at work and may serve as role models to encourage student consumption of water instead of SSBs.
