Community Dining, Walking, and Glucose in Older Adults

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

In this study, adults aged 60–79 with prediabetes will participate in two 6-day meal conditions, one at home and one at a subsidized community dining site, in random order. Participants will wear continuous glucose monitors and activity trackers to measure postmeal glucose responses, daily glucose patterns, and steps after meals under real-life conditions. Researchers will compare the community dining setting to home meals to see if dining away from home increases walking, improves glucose metrics after meals, and influences loneliness and meal experience. The approach treats subsidized dining as a real-world meal context rather than a prescriptive intervention. No walking target will be set; participants may move or rest as they prefer after meals.
