Study population: This study will evaluate the pathophysiological features of cardiovascular disease in youth-onset type 2 diabetes (Y-T2DM) using a multi-level, multi-domain approach of socio-ecological risk factors (societal, community, and individual). We will employ a prospective, observational study design in youth aged 12-25 years to compare Y-T2DM with age and BMI-matched youth with overweight or obesity (Y-OW) and age-matched healthy lean peers (Y-Lean). The study will also include a single-day visit for biological parents of enrolled Y-T2DM, Y-OW and Y- lean, to assess parental factors involved in the pathophysiology of cardiovascular disease in Y-T2DM.

Brief summary: Background:

Type 2 diabetes is a disease that affects blood sugar levels. Complications can include heart and blood vessel (vascular) diseases. Rates of type 2 diabetes have tripled in children and young adults over the last 40 years. Vascular diseases are also increasing in young people.

Objective:

To learn more about factors, including type 2 diabetes, that may cause vascular disease in young people.

Eligibility:

People aged 12 to 25 years who (1) have type 2 diabetes; (2) are overweight but not diabetic; (3) or are lean and healthy. Biological parents are also needed.

Design:

Young participants will visit the NIH clinic once a year for up to 25 years. Each visit will take 4 days. Before each visit, participants will wear devices to track their sleep, activity, and blood sugar levels for 7 to 10 days.

At each visit, participants will have tests including:

Samples: They will provide blood, urine, and stool samples.

Heart: They will ride a stationary bike for 6 minutes with stickers applied to their chest.

Scans: They will lie on a bed that slides into a tube; the machine will take pictures of the inside of their body.

Energy: They will wear a hood over their head to measure the air they breathe.

Social stress: They will give a speech for 10 minutes to show their body s response to stress.

Glucose: They will drink a sweet drink to see how their blood sugar changes.

Biological parents will have 1 study visit. They will have blood tests. They will fill in questionnaires about their lifestyle and stress.

Detailed description: Study Description:

This study will evaluate the pathophysiological features of cardiovascular disease in youth-onset type 2 diabetes (Y-T2DM) using a multi-level, multi-domain approach of socio-ecological risk factors (societal, community, and individual). We will employ a prospective, observational study design in youth aged 12-25 years to compare Y-T2DM with age and BMI-matched youth with overweight or obesity (Y-OW) and age-matched healthy lean peers (Y-Lean). The study will also include a single-day visit for biological parents of enrolled Y-T2DM, Y-OW and Y- lean, to assess parental factors involved in the pathophysiology of cardiovascular disease in Y-T2DM.

Objectives:

Primary Objectives:

* To compare pulse wave velocity (PWV) at baseline in Y-T2DM vs Y-OW and age-matched peers Y-Lean.
* To compare augmentation index (Aix) at baseline in Y-T2DM vs Y-OW and age-matched peers Y-Lean.
* To compare pulse wave velocity (PWV) at 5 years in Y-T2DM vs Y-OW and age-matched peers Y-Lean.
* To compare augmentation index (Aix) at 5 years in Y-T2DM vs Y-OW and age-matched peers Y-Lean.

Secondary Objectives:

In Y-T2DM vs. Y-OW vs. Y-Lean youth,

* To evaluate coronary artery structure and endothelial function at baseline and 5 years.
* To evaluate the relationship of pulse wave velocity and coronary artery structure \& endothelial function with atherogenic and remnant lipoproteins.

Exploratory Objectives:

In Y-T2DM vs. Y-OW vs. Y-Lean youth,

* To evaluate annual change in vascular aging (measured by the change in pulse wave velocity and endothelial function).
* To evaluate the relationship of physiologic, psychological stress (measured with the allostatic load score, ALS), psychosocial and behavioral factors with vascular aging.
* To evaluate biomarkers for vascular aging; ex. Beta-cell function, insulin resistance, inflammatory markers, and novel lipid parameters.
* To evaluate the association of polygenic risk scores (PRS) in Y-T2DM and with changes in glucose and metabolic profiles (e.g., triglycerides) over time.
* To evaluate differences in epigenetic aging in youth and parents.
* To determine the prevalence rates of major adverse cardiovascular events (MACE)
