Clinical Trial Summary

This research examines whether biofeedback of glucose (i.e., knowledge of one's own glucose levels) in non-diabetic participants affects their health behaviours (e.g., eating, nutrition, exercise, etc.). This study utilizes wearable continuous glucose (CGM) technology, which provides personalized feedback to participants to allow them to self-monitor their own glucose levels.

Description:

The purpose of this research is to examine whether self-monitoring and biofeedback of glucose levels improves health outcomes in non-diabetic participants. All participants will receive a continuous flash glucose monitor (consisting of an adhesive patch sensor and a handheld reader device) to wear for 14 days. Participants will be randomized into one of 2 groups: those receiving biofeedback (the ability to visualize their glucose levels via the handheld device), and the control group (receiving no biofeedback because the handheld device monitor will be occluded with black tape). Participants' objective and self-report health metrics will be measured before and after the 14-day intervention. The goal is to examine whether the biofeedback condition influences any daily activities or physiological measurements compared to the control condition, as a direct result of self-monitoring glucose levels.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Weight in kg	Weight in kg	2 weeks
Primary	Body Mass Index (BMI)	Height in cm and weight in kg will be used to calculate BMI	2 weeks
Primary	Body fat %	Using a smart scale	2 weeks
Primary	Resting heart rate	Using a sphygmomanometer with heart rate sensor	2 weeks
Primary	Resting blood pressure (systolic and diastolic)	Using a sphygmomanometer	2 weeks
Primary	Self-reported positive and negative affect	Positive and Negative Affect Schedule (PANAS; Watson et al., 1988). The scale consists of 20 items (10 for Positive Affect; 10 for Negative Affect), with each item rated on a 5-point scale of 1 (not at all) to 5 (extremely). Items are summed for Positive affect and Negative affect, with higher scores indicating a higher level of affect in each respective scale.	2 weeks
Primary	Self-reported general health	12-Item Short-Form Health Survey (SF-12; Ware et al., 1996). The scale measures overall general self-reported physical and mental health using 12 items, on 2 to 6-point ordinal scales. The range of possible total scores is 12 to 48, with higher scores indicating better health.	2 weeks
Primary	Self-reported perceived stress	Perceived Stress Scale (Cohen et al., 1983; Cohen & Williamson, 1988). This is a 4-item scale that measures overall stress with each item evaluated on a 5-point Likert scale. The range of possible total scores is 0 to 16, with higher scores indicating more stress.	2 weeks
Primary	Self-reported sleep quality	Pittsburgh Sleep Quality Index (Buysse et al., 1989). This is a 19-item scale that measures self-reported sleep quality and sleep disturbances, comprised of open-ended questions and scaled items evaluated on a 4-point Likert scale. The range of possible total scores is 0 to 21, with higher scores indicating poorer sleep quality.	2 weeks
Primary	Self-reported general well-being	Satisfaction with Life Scale (Diener et al., 1985). This is a 5-item scale that measures overall well-being with each item evaluated on a 7-point Likert scale. The range of possible total scores is 5 to 35, with higher scores indicating higher well-being.	2 weeks
