Among the 51 studies in Prediabetic State with a site in China, from their registry updates:
This study will examine whether eating lunch and dinner at a subsidized community dining site affects postmeal walking and blood glucose patterns in older adults. Participants will be community-dwelling adults aged 60 to 79 years who are eligible for a local elderly meal subsidy and have prediabetes or elevated blood glucose risk.
Each participant will complete two 6-day meal conditions in random order. In one condition, participants will eat lunch and dinner at home. In the other condition, participants will eat lunch and dinner at a subsidized community dining site. Participants will wear a continuous glucose monitor and an activity tracker so the study team can measure postmeal glucose levels, daily glucose patterns, and steps after meals.
The study will compare community dining with home eating to determine whether community dining increases postmeal walking, improves postmeal glucose responses, and affects loneliness and meal experience.
Subsidized community dining programs are designed to improve access to affordable meals for older adults, but they may also influence daily movement, social interaction, and metabolic health. Eating at a community dining site may encourage older adults to leave home, walk before or after meals, and interact with others in a shared meal environment.
This study will evaluate subsidized community dining as a real-world meal setting rather than as a prescribed exercise or dietary treatment. Participants will complete both study conditions: home eating and community dining. During the community dining condition, participants will eat lunch and dinner at a subsidized community dining site. During the home-eating condition, participants will eat lunch and dinner at home using meals designed to approximate the energy and macronutrient composition of the community dining meals.
The study will use continuous glucose monitoring and wearable activity tracking to measure postmeal glucose responses, daily glucose profiles, and postmeal steps under free-living conditions. No walking target will be prescribed. After each lunch and dinner, participants will be free to walk, sit, rest, remain at the dining site, or return home according to their usual preference.
The study will also assess loneliness and meal-condition experience to explore whether the dining setting affects social and experiential aspects of eating. Findings may help determine whether subsidized community dining can function not only as food assistance, but also as community-based infrastructure that supports healthy aging.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Participants will complete 6 days of eating lunch and dinner at home, followed by 6 days of eating lunch and dinner at a subsidized community dining site.
Behavioral: Subsidized Community Dining · Behavioral: Home Eating
Participants will complete 6 days of eating lunch and dinner at a subsidized community dining site, followed by 6 days of eating lunch and dinner at home.
Behavioral: Subsidized Community Dining · Behavioral: Home Eating
Participants will eat lunch and dinner at a subsidized community dining site for 6 days. No walking target or exercise prescription will be given. After each meal, participants will be free to walk, sit, rest, remain at the dining site, or return home according to their usual preference.
Participants will eat lunch and dinner at home for 6 days using a standardized Chinese meal rotation designed to approximate the energy and macronutrient composition of the community dining meals.
Meal-Level 0- to 90-Minute Postprandial Glucose Incremental Area Under the Curve
Postprandial glucose incremental area under the curve (iAUC) will be calculated for each lunch and dinner from exported timestamped continuous glucose monitoring data using the trapezoidal rule. Baseline glucose will be defined as the mean continuous glucose monitoring value during the fixed 30-minute premeal baseline window. The postprandial calculation window will extend from meal completion through 90 minutes after meal completion.
Time frame: Study Days 2-13; fixed premeal baseline window through 90 minutes after completion of each lunch and dinner during the 12-day randomized meal-condition period.
Meal-Level 0- to 90-Minute Postmeal Step Count
Postmeal step count will be obtained from the wearable-device activity session started immediately after meal completion and stopped 90 minutes later. This outcome will be assessed separately after lunch and dinner.
Time frame: Study Days 2-13; from meal completion through 90 minutes after completion of each lunch and dinner during the 12-day randomized meal-condition period.
Meal-Level Peak Postprandial Glucose
Peak postprandial glucose will be defined as the highest continuous glucose monitoring value during the 90-minute postmeal window after each lunch and dinner.
Time frame: Study Days 2-13; from meal completion through 90 minutes after completion of each lunch and dinner during the 12-day randomized meal-condition period.
Meal-Level Time to Peak Postprandial Glucose
Time to peak postprandial glucose will be defined as the time, in minutes, from meal completion to the highest continuous glucose monitoring value during the 90-minute postmeal window after each lunch and dinner.
Time frame: Study Days 2-13; from meal completion through 90 minutes after completion of each lunch and dinner during the 12-day randomized meal-condition period.
Daily 24-Hour Mean Glucose
The 24-hour mean glucose will be calculated for each analytic day using valid continuous glucose monitoring readings.
Time frame: Study Days 2-13; over each 24-hour analytic day during the 12-day randomized meal-condition period.
Daily Time Above Range
Time above range will be calculated for each analytic day as the percentage of valid continuous glucose monitoring readings above 7.8 mmol/L.
Time frame: Study Days 2-13; over each 24-hour analytic day during the 12-day randomized meal-condition period.
Daily Combined Postmeal Steps
Daily combined postmeal steps will be calculated as the sum of 0- to 90-minute postmeal steps after lunch and dinner on the same analytic day.
Time frame: Study Days 2-13; summed across the lunch and dinner 90-minute postmeal windows on each 24-hour analytic day during the 12-day randomized meal-condition period.
Total Daily Steps
Total daily steps will be obtained from the wearable activity tracker for each analytic day.
Time frame: Study Days 2-13; over each 24-hour analytic day during the 12-day randomized meal-condition period.
End-of-Condition Loneliness Score
Loneliness will be assessed using the 6-item De Jong Gierveld Loneliness Scale. The total score ranges from 0 to 6, with higher scores indicating greater loneliness. The scale will be administered at baseline and at the end of each 6-day meal condition. End-of-condition loneliness scores will be compared between the home-eating and community-dining conditions.
Time frame: Baseline and end of each 6-day meal condition during the 12-day randomized meal-condition period.
End-of-Condition Meal-Condition Experience and Satisfaction Score
Meal-condition experience and satisfaction will be assessed using a study-specific 4-item scale covering relaxation during meals, comfort of the meal environment, opportunities for communication, and willingness to go outdoors and be active. Each item will be rated on a 5-point Likert scale. The mean score ranges from 1 to 5, with higher scores indicating a more favorable meal-condition experience.
Time frame: End of each 6-day meal condition during the 12-day randomized meal-condition period.
