Abstrakt: Objectives: We evaluated a low-cost strategy for schools to improve the convenience and appeal of drinking water.
Methods: We conducted a group-randomized, controlled trial in 10 Boston, Massachusetts, schools in April through June 2013 to test a cafeteria-based intervention. Signage promoting water and disposable cups were installed near water sources. Mixed linear regression models adjusting for clustering evaluated the intervention impact on average student water consumption over 359 lunch periods.
Results: The percentage of students in intervention schools observed drinking water during lunch nearly doubled from baseline to follow-up compared with controls (+ 9.4%; P < .001). The intervention was associated with a 0.58-ounce increase in water intake across all students (P < .001). Without cups, children were observed drinking 2.4 (SE = 0.08) ounces of water from fountains; with cups, 5.2 (SE = 0.2) ounces. The percentage of intervention students observed with sugar-sweetened beverages declined (-3.3%; P < .005).
Conclusions: The current default of providing water through drinking fountains in cafeterias results in low water consumption. This study shows that an inexpensive intervention to improve drinking water's convenience by providing cups can increase student water consumption.
