This study aimed to examine whether promotion of water intake in the general population in and of itself reduces sugar-sweetened beverage (SSB) consumption independent from interventions that target SSBs. Seven electronic databases were systematically searched: PubMed, Embase, PsycInfo, CINAHL Complete, Cochrane Central Register of Controlled Trials, CAB Direct, and Web of Science. The search hedge included concepts of drinking water, sweetened beverages, and clinical or controlled or longitudinal studies. We identified 5652 publications, chose 107 for full-text review and selected 17 for this review. Two authors independently extracted data using predefined data fields and rated study quality. Seven studies reported a decrease in sugar-sweetened beverage consumption. Among the eight studies that successfully increased water intake, five reported beneficial effects on SSB intake while three did not. Of the five positive studies, three were at serious or high risk of bias. Studies with decrease in sugar-sweetened beverage consumption tended to include a home-based or individually focused intervention. This review found little evidence that interventions aimed solely at increasing water consumption reduce sugar-sweetened beverage intake. Further research is needed to investigate whether interventions that combine water promotion and SSB reduction strategies could be synergistic for reducing SSB intake. SSB reduction approaches at this time should focus directly on SSBs.
A Systematic Review of the Effectiveness of Promoting Water Intake to Reduce Sugar-sweetened Beverage Consumption
Stories of Success: A Qualitative Examination of Contributors to Excellence in School Drinking Water Access
Drinking water instead of beverages with added sugar can help prevent obesity and cavities and promote overall health. Children spend much of their day in school, where they have variable access to drinking water. In 2010, federal and state law required California public schools to provide free potable water to … More
Policymakers worldwide are considering requiring warnings for sugary drinks. A growing number of experimental studies have examined sugary drink warnings’ impacts, but no research to our knowledge has synthesized this literature. To inform ongoing policy debates, this study aimed to identify the effects of sugary drink warnings compared with control … More
