[BDSP. Notice produite par INIST-CNRS J7pjFR0x. Diffusion soumise à autorisation]. Objectives. We assessed whether a 2-phase labeling and choice architecture intervention would increase sales of healthy food and beverages in a large hospital cafeteria. Methods. Phase 1 was a 3-month color-coded labeling intervention (red =unhealthy, yellow =less healthy, green =healthy). Phase 2 added a 3-month choice architecture intervention that increased the visibility and convenience of some green items. We compared relative changes in 3-month sales from baseline to phase 1 and from phase 1 to phase 2. Results. At baseline (977793 items, including 199513 beverages), 24.9 % of sales were red and 42.2 % were green. Sales of red items decreased in both phases (P <. and green items increased in phase the largest changes occurred among beverages. red beverages decreased during further bottled water but did not increase at on-site comparison cafeterias conclusions. a color-coded labeling intervention improved sales of healthy was enhanced by choice architecture intervention.>
