Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Detailed Description

The Sugar Challenge Study is a real-world, longitudinal study aimed at understanding the impact of lifestyle (i.e. food choices, physical activity and sleep patterns), genetics and personalized lifestyle recommendations on blood glucose levels, blood pressure, immune system status, stress hormone levels and microbiome composition. The purpose of this 10-day observational study was to primarily elucidate the impact of food choices, physical activity, and sleep patterns on an individual's blood glucose. In addition, we probed if continuous and personalized feedback to participants would improve glycemic control acutely through better decision making. Multiple investigations may be performed over an indefinite period of time to improve the understanding of these interconnected relationships. For example, we will perform studies to understand an individual's blood glucose response to an oral glucose load or mixed meal. We will also perform studies to determine the phenotype (clinical, metabolic, or immunologic) associated with a particular genotype. The data collected will be analyzed using proprietary machine learning methods.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Assessment of percent of total time monitored that blood glucose is in range 70-180 mg/dL
Time Frame: 10 Continuous Days
The percentage of time an individual remains within a target blood glucose range through the measure of Continuous Glucose Monitor. Ranges defined by the American Diabetes Association (ADA). Current guidelines in range are to 70% of time within 70-180 mg/dL range.
10 Continuous Days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
