Establishing a Virtual Health Community Management Model for Pre-Diabetes Patients

Research on the Construction and Driving Mechanisms of an Interactive Management Model for Pre-diabetic Patient Groups Based on Virtual Health Communities

This study builds upon the previously developed virtual health community platform, aiming to address the group characteristics and psychological traits of prediabetic patients. By employing intervention mapping to construct a group interaction management model, it seeks to develop a mobile platform integrating "gamified knowledge acquisition and motivation", "immersive lifestyle practice experiences", and "sustained community interaction management". The primary focus is on fostering patients' continuous and proactive engagement. Subsequently, a single-arm controlled trial will validate the model's efficacy, aiming to address the health management challenges faced by China's substantial prediabetic population. This initiative seeks to provide theoretical foundations and practical support for primary prevention strategies targeting other chronic diseases and at-risk cohorts.

Arms and Interventions

Participant Group / Arm

Intervention / Treatment

Experimental: Pre-diabetes Virtual Community Experience Group

Other: Pre-diabetes Virtual Community; By collecting general information, physical measurements, glucose and lipid metabolism indicators, dietary habits, and exercise routines from prediabetic patients, these details are input into the virtual community programme for prediabetes. The virtual community evaluates the input data, alerts healthcare professionals to patients requiring immediate intervention, and provides guidance for the forthcoming week regarding diet, exercise, and other health aspects (including dietary and exercise advice for prediabetic patients), alongside risk alerts.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Physical activity	Participants self-reported their daily physical activity levels, with the International Physical Activity Questionnaire (IPAQ) used to assess the frequency, duration, and intensity (i.e., light, moderate, and vigorous activities) of physical activity across different domains (work, transportation, household, and leisure) over the past 7 days.	From enrolment to the conclusion of the study, 2 weeks.
Diet	Participants self-reported their daily meal consumption through periodic 24-hour dietary recalls or food diaries. These data were then used to calculate the Planetary Health Diet Score, providing a weekly assessment of diet quality.	From enrolment to the conclusion of the study, 2 weeks.
Fasting blood glucose		From enrolment to the conclusion of the study, 2 weeks.
Two-hour postprandial blood glucose		From enrolment to the conclusion of the study, 2 weeks.
Task Completion Rate	Task Completion Rate is defined as the percentage of target users who successfully met the task criteria within the specified time frame and user scope. It directly reflects the implementation efficiency of the intervention and user adherence (e.g., dietary logging rate, exercise plan execution rate). Formula: Task Completion Rate = (Number of users who successfully completed the task / Total number of target users) × 100%.	From enrolment to the conclusion of the study, 2 weeks.

Secondary Outcome Measures

Outcome Measure	Time Frame
Body Mass Index (BMI)	From enrolment to the conclusion of the study, 2 weeks.
Total cholesterol	On the first day of enrolment, at the conclusion of the intervention two weeks later.
Triglycerides	On the first day of enrolment, at the conclusion of the intervention two weeks later.
High-density lipoprotein cholesterol (HDL-C)	On the first day of enrolment, at the conclusion of the intervention two weeks later.
Low-density lipoprotein cholesterol (LDL-C)	On the first day of enrolment, at the conclusion of the intervention two weeks later.
