This study evaluated orders of adult menu items designated as healthier at the Silver Diner, a regional full-service restaurant chain serving over 4 million customers annually. This restaurant implemented a healthier childrenâs menu in April 2012. Orders of adult menu items were abstracted from before (September 2011âMarch 2012; PRE; n = 1,801,647) and after (September 2012âMarch 2013; POST; n = 1,793,582) the healthier childrenâs menu was introduced. EntrĂ©es, appetizers, and sides listed as healthier options on the menu were coded as healthier. PRE to POST changes in the percentage of orders of healthier items, soda, and dessert were evaluated using McNemar tests of paired proportions. Orders of healthier entrĂ©es, appetizers, and sides on the adult menu increased PRE to POST (8.9% to 10.4%, 25.5% to 27.5%, and 7.3% to 9.3%, respectively), and soda and dessert orders decreased (23.2% to 21.7% and 29.0% to 28.3%, respectively). All shifts were statistically significant (p < 0.0001). Our findings demonstrate improvements in orders of healthier adult menu options during the same time frame as a healthy childrenâs menu change. Future research can help elucidate mechanisms to inform future health promotion efforts in restaurants in ways that have the potential to impact both adults and children.
