Summary

The purpose of the study is to test the impact of a multilevel workplace intervention (hospital-wide sales ban on sugar-sweetened beverages (SSBs) and individual-level brief counseling) on employee health.

Detailed description

This double-randomized controlled trial of a multilevel workplace intervention that combines an employer-sponsored sales ban on sugar-sweetened beverages (SSBs) with brief counseling to support reduced consumption will test how well each intervention works alone, whether they work better in combination than separately, and whether or not changes in SSB cravings mediate these effects. Sutter Health worksites will be randomly assigned to either a control condition or to implement a sales ban on SSBs. Within all sites, employees will be randomized to receive/not receive a brief counseling intervention focused on reducing SSB consumption. Participants will complete self-report questionnaires, give blood samples, and provide measurements of waist circumference, height, and weight. These data will be analyzed to determine the effects of the interventions, both separately and in combination.
