Cafeteria purchases feedback helps employees make healthier food choices

Automated emails and letters that provide personalized feedback related to cafeteria purchases at work may help employees make healthier food choices. That’s the conclusion of a new study that was led by investigators at Massachusetts General Hospital (MGH) and is published in JAMA Network Open.

As many adults spend half (and sometimes more) of their waking hours working, the workplace provides a unique opportunity to promote health with programs that target obesity, unhealthy diets, and other risk factors for chronic diseases and premature death.

Building on findings from previous studies, researchers designed the ChooseWell 365 clinical trial to test a 12-month automated, personalized behavioral intervention to prevent weight gain and improve diet in hospital employees. For the trial, 602 MGH employees who regularly used the hospital’s cafeterias were randomized to an intervention group or a control group. For one year, participants in the intervention group received two emails per week that included feedback on their previous cafeteria purchases and offered personalized health and lifestyle tips. They also received one letter per month with comparisons of their purchases with those of their peers, as well as financial incentives for healthier purchases. Control participants received one letter per month with general healthy lifestyle information.
