About this study

Official title: The Influence of Non-Caloric Artificial Sweeteners on the Metabolome, Body Composition, and Glycemic Control in Youth With Type 1 Diabetes

The investigators aim to further the understanding of environmental factors that may underlie variations in body composition seen in youth with Type 1 diabetes (T1D). Non-caloric artificial sweeteners, broadly consumed in many individuals with T1D, are a modifiable dietary factor that may be associated with negative health outcomes, particularly those relevant to the future risk of diabetes-related complications.

Investigators will measure body composition (the amount of fat and muscle in the body and where the fat is stored) using a bioelectrical impedance analysis machine and DEXA scanner. Blood will be drawn for the following labs: HbA1c, lipid panel, comprehensive metabolic panel and leptin. Participants will also answer questions about their diets and consumption of artificial sweeteners.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Bioelectrical Impedance AnalysisDiagnostic test

    Also called BIA

    BIA is a radiation-free and clinically accessible measure of body composition [47, 49]. An electrode is placed on the youth's extremities and they are asked to sit for 10 minutes. The youth's height and weight is manually inputted and the measure is obtained (approx. 90 seconds to complete). BIA sends a low level of electrical current through the body and measures the impedance to the current based on fat, muscle, bones providing a measure of body composition.

  • Total Body Dual-energy X-ray AbsorptiometryDiagnostic test

    Also called DXA

    The DXA total body scan provides measurements of percent body fat, lean and fat free mass throughout the body. Youth lay on a table while the machine moves around them. The process takes about 3 minutes and 20 seconds.

  • Blood drawDiagnostic test

    Blood will be drawn to assess the following labs: HbA1c, leptin, lipid panel and comprehensive metabolic panel.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Quantify artificial sweetener consumption in youth with type 1 diabetes

    To quantify artificial sweetener consumption patterns in a cohort of youth with T1D through novel food frequency questionnaires (Non-caloric artificial sweetener Food Frequency Questionnaire for Food and the Non-caloric artificial sweetener Food Frequency Questionnaire for Beverages) and bioassay

    Measured: Study Duration (1 year)

  2. Examine the relationship between artificial sweeteners and body composition

    To characterize the relationship between artificial sweetener consumption and measures of body composition, as measured by bioelectrical impedance analysis and DXA scanning, which provide information on the amount and distribution of fat and muscle in the body.

    Measured: Study Duration (1 year)

  3. Examine the relationship between artificial sweeteners and kidney function

    To determine if the level of artificial sweeteners is associated with the serum creatinine level.

    Measured: Study Duration (1 year)

  4. Examine the relationship between artificial sweeteners and liver function

    To determine if the level of artificial sweeteners is associated with serum AST and ALT levels

    Measured: Study Duration (1 year)

  5. Examine the relationship between artificial sweeteners and lipid levels.

    To characterize the relationship between artificial sweetener consumption and metabolism and the levels of fasting lipids (triglyceride level, HDL, LDL, and total cholesterol).

    Measured: Study Duration (1 year)

  6. Examine the relationship between artificial sweeteners and metabolism.

    To characterize the relationship between artificial sweetener consumption and metabolism, as measured by a leptin level.

    Measured: Study Duration (1 year)

  7. Examine the relationship between artificial sweeteners and glycemic control

    To characterize the relationship between artificial sweetener consumption and measures of glycemic control, as determined by the presence or absence of microalbuminuria.

    Measured: Study Duration (1 year)

  8. Examine the relationship between artificial sweeteners and glycemic control

    To characterize the relationship between artificial sweetener consumption and measures of glycemic control, as measured by total daily insulin dose.

    Measured: Study Duration (1 year)

  9. Examine the relationship between artificial sweeteners and glycemic control

    To characterize the relationship between artificial sweetener consumption and measures of glycemic control, as measured by the percentage of time participants are within ideal range for blood glucose levels (as measured by glucose monitors.)

    Measured: Study Duration (1 year)

  10. Examine the relationship between artificial sweeteners and hemoglobin A1c

    To characterize the relationship between artificial sweetener consumption and measures of glycemic control, as measured by serum HbA1c.

    Measured: Study Duration (1 year)

Questions about this trial

What is this clinical trial studying?

An observational study of Type 1 Diabetes Mellitus, run by Medical College of Wisconsin at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 16 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Quantify artificial sweetener consumption in youth with type 1 diabetes (time frame: Study Duration (1 year)). The study lists 10 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Mar 2026.
