Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The Sunnybrook Type 2 Diabetes Study (S2DS) is a prospective observational study of people with prediabetes or Type 2 Diabetes Mellitus (T2DM), that aims to understand the aetiologies, manifestations, and clinical consequences of mood and cognitive complications. The study recruits from the services at Sunnybrook Health Sciences Centre and from the neighbouring University Health Network Toronto Rehabilitation Institute Cardiac Rehabilitation Program.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The S2DS is a prospective observational study of people with prediabetes or T2DM recruited from Sunnybrook Health Sciences Centre and the neighbouring University Health Network Toronto Rehabilitation Institute Cardiac Rehabilitation Program. Participants recruited from Sunnybrook are receiving care from services there (e.g. Family Medicine, Endocrinology, and the Sunnybrook Diabetes Education Centre). Participants recruited from the Toronto Rehab are undertaking a 6-month stepped hybrid (home and clinic based) aerobic plus resistance exercise intervention as part of a program at that site (e.g. the Diabetes, Exercise, and Healthy Lifestyle Program).

Study assessments are conducted at baseline, 3 months, 6 months and 18 months. Main outcomes include cognitive performance, assessed using a detailed neurocognitive battery, and mood symptoms assessed via research criteria for a depressive episode and self-report instruments. Other lifestyle factors are also examined, including physical activity, sleep quality, diet, and subjective stress. Diabetes complications and characteristics are monitored, as are all concomitant medications and supplements. With permission, participant data are linked prospectively to public health records to ascertain long-term outcomes and health services utilization.

The cohort is characterized using biological, neuroimaging and biometric measures. Fasting morning blood and urine samples are taken at each assessment. Serum, plasma, whole blood, and white blood cells are bio-banked for biochemical, genetic and other analyses. The MRI study includes a 1.5 hr MRI scan at 3.0 T. Sequences performed include structural imaging (T1, T2, DTI and FLAIR) and resting state functional MRI. Two optional sub-studies are offered: a cerebrovascular reactivity MRI protocol, and a sleep quality and apnea protocol (baseline, 6 month and 18 month visits). The sleep study uses an overnight wearable sleep monitor.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

UHN Toronto Rehab

Participants with prediabetes of T2DM undertaking a 6-month stepped hybrid (home and clinic based) aerobic plus resistance exercise intervention as per the site's standard protocol (Diabetes Exercise and Healthy Lifestyle Program).

Diabetes Exercise and Healthy Lifestyle Program

Intervention Type BEHAVIORAL

The program combines exercise, education and healthy lifestyle behaviour changes. Participants will begin the program with a cardiopulmonary exercise assessment. Then the team will create a personalized program of exercise based on functional abilities and personal goals. Participants will attend 1 supervised exercise class a week, which includes a warm-up and stretching routine, aerobic exercise (walking, stationary cycling or elliptical machine), resistance training and an educational session. This program also offers peer-to-peer support and encourages participants to carry out their own exercise program at home 4 more times per week and to keep a weekly exercise diary to help them with their progress.

Sunnybrook Health Sciences Centre

Participants with prediabetes or T2DM receiving care from an outpatient service at Sunnybrook Health Sciences Centre.

Outpatient care

Intervention Type OTHER

Participants receive usual care from outpatient services, which may include Endocrinology, Family Medicine, or Diabetes Education
