Prevalence and Risk Factors of Metabolic-Associated Hepatic Steatosis in Individuals Living With Type 1 Diabetes (STEA-DT1)

March 19, 2026 updated by: Sarah Beland Bonenfant, Institut de Recherches Cliniques de Montreal

The goal of this observational cross-sectional study is to assess the prevalence and stage of Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD), specifically liver steatosis and fibrosis in adults aged 18 and older living with type 1 diabetes or Latent Autoimmune Diabetes in Adults (LADA) in Quebec.

The main questions it aims to answer are:

  1. What is the prevalence and severity of liver steatosis and fibrosis among people living with type 1 diabetes in Québec?
  2. Are there patients with type 1 diabetes who have advanced, undiagnosed stages of liver disease that require management but are missed by current standard care practices?

Researchers will compare three participant subgroups based on adiposity (a control group without increased adiposity, an overweight group with increased adiposity, and an obesity group with increased adiposity) to see if the prevalence and severity of hepatic steatosis and fibrosis are highest in the obesity group and lowest in the control group. They will also explore if variables and potential risk factors associated with liver disease differ across these subgroups.

Participants will attend a single study visit where they will be asked to:

  • Provide clinical data through laboratory analyses.
  • Undergo specific clinical procedures.
  • Complete validated questionnaires.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Control group
Adults with type 1 diabetes or LADA without increased adiposity and without any BMI-based criterion.
Other: Adiposity and BMI Classification
Participants are classified into three subgroups based on their BMI and the presence of increased adiposity. Increased adiposity is defined by waist circumference, waist-to-hip ratio, or waist-to-height ratio exceeding sex- and ethnicity-specific thresholds. The subgroups are: a control group (no increased adiposity), an overweight group (BMI 25.0-29.9 kg/m² with increased adiposity), and an obesity group (BMI ≥ 30 kg/m² with increased adiposity).
Obesity Group
Adults with T1D or LADA with a BMI of 30 kg/m² or higher combined with increased adiposity.
Other: Adiposity and BMI Classification
Participants are classified into three subgroups based on their BMI and the presence of increased adiposity. Increased adiposity is defined by waist circumference, waist-to-hip ratio, or waist-to-height ratio exceeding sex- and ethnicity-specific thresholds. The subgroups are: a control group (no increased adiposity), an overweight group (BMI 25.0-29.9 kg/m² with increased adiposity), and an obesity group (BMI ≥ 30 kg/m² with increased adiposity).
Overweight group
Adults with T1D or LADA with a BMI between 25.0 and 29.9 kg/m² combined with increased adiposity
Other: Adiposity and BMI Classification
Participants are classified into three subgroups based on their BMI and the presence of increased adiposity. Increased adiposity is defined by waist circumference, waist-to-hip ratio, or waist-to-height ratio exceeding sex- and ethnicity-specific thresholds. The subgroups are: a control group (no increased adiposity), an overweight group (BMI 25.0-29.9 kg/m² with increased adiposity), and an obesity group (BMI ≥ 30 kg/m² with increased adiposity).

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 liver fibrosis using FibroScan
Time Frame: Baseline (Day 1 / Single Study Visit)
Liver fibrosis severity will be quantified using liver stiffness measurement (LSM) obtained via FibroScan. The measurement is expressed in kilopascals (kPa). Higher values indicate more severe fibrosis, categorized as: < 8.0 kPa (Normal), 8.0 to 9.6 kPa (Significant fibrosis), 9.7 to 13.5 kPa (Advanced fibrosis), and > 13.5 kPa (Cirrhosis)
Baseline (Day 1 / Single Study Visit)
Degree of liver steatosis assessment
Time Frame: Baseline (Day 1 / Single Study Visit)
Liver steatosis will be quantified using the Controlled Attenuation Parameter CAP value generated simultaneously during the FibroScan assessment. The measurement is expressed in decibels per meter (dB/m). Higher values indicate a higher degree of steatosis, categorized as: < 294 dB/m (<5% steatosis), 294 to 310 dB/m (5 to 30%), 311 to 330 dB/m (30 to 60%), and > 330 dB/m (>60%).
Baseline (Day 1 / Single Study Visit)

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.
Outcome Measure
Measure Description
Time Frame
Anthropometric Assessment: Body mass Index (BMI)
Time Frame: Baseline (Day 1 / Single Study Visit)
Body mass index (BMI: kg/m^2) will be calculated using weight (kg) and height (cm) to compare FibroScan results across predefined subgroups.
Baseline (Day 1 / Single Study Visit)
Anthropometric Assessment: Waist circumference
Time Frame: Baseline (Day 1 / Single Study Visit)
Waist circumference and hip circumference (cm) will be used to compare FibroScan results across predefined subgroups.
Baseline (Day 1 / Single Study Visit)
Adiposity-Based Subgroup Classification
Time Frame: Baseline (Day 1 / Single Study Visit)
Participants will be categorized into three groups (e.g., Low, Medium, High adiposity) based on a composite of iDXA
Baseline (Day 1 / Single Study Visit)

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Dietary Intake (RxFood Diary)
Time Frame: Baseline (Day 1 / Single Study Visit)
Average daily caloric intake calculated over 3 days
Baseline (Day 1 / Single Study Visit)
Alcohol Use Disorders Identification Test (AUDIT) Score
Time Frame: Baseline (Day 1 / Single Study Visit)
Total score from the 10-item AUDIT questionnaire to assess alcohol consumption. Range: 0 to 40. A higher score indicates a greater risk of hazardous and harmful alcohol use, as well as potential alcohol dependence (A score of 8 or more is typically considered the threshold for hazardous drinking).
Baseline (Day 1 / Single Study Visit)
Physical Activity Level (IPAQ)
Time Frame: Baseline (Day 1 / Single Study Visit)
Total physical activity expressed as Metabolic Equivalent of Task (MET)-minutes per week. A higher score (higher MET-minutes/week) indicates a higher level of physical activity.
Baseline (Day 1 / Single Study Visit)
Eating Behavior (Three-Factor Eating Questionnaire: TFEQ)
Time Frame: Baseline (Day 1 / Single Study Visit)
The TFEQ-R18 is an 18-item validated tool used to assess three domains of eating behavior: Cognitive Restraint, Uncontrolled Eating, and Emotional Eating. Raw scores are transformed to a 0-100 scale. For all sub-scales, higher scores indicate a greater presence of that specific eating behavior (e.g., higher emotional eating or higher restraint).
Baseline (Day 1 / Single Study Visit)
