This is a single-center observational study on adolescents to determine predictors of the early steps of the formation of atherosclerosis and to quantify their influence on Intima-Media-Thickness of the carotid artery and the aorta and on the Pulse-Wave Velocity.
A long-term follow-up by means of record linkage is furthermore planned to evaluate the effect of early atherosclerosis and the cardiovascular risk profile on future morbidity with a special focus cardio- and cerebrovascular events.
EVA4YOU is a cross-sectional study enrolling 3000 students and apprentices aged between 14 and 19 years. Examinations are conducted at schools and companies throughout Tyrol, Austria and include laboratory measurements; standardized medical interviews; anthropometry; liver elastography; ultrasonography of the carotid artery and the aorta, and blood pressure, bioelectrical impedance; visceral abdominal fat-tissue-thickness measurement, pulse-wave velocity measurements.
The study hypothesis is that the cardiovascular risk factors measured already influence the formation of atherosclerosis (measured as carotid and aortic Intima-Media Thickness and Pulse-Wave-Velocity) in adolescents.
A long-term follow-up by means of record linkage is furthermore planned to evaluate the effect of early atherosclerosis and the cardiovascular risk profile on future morbidity with a special focus cardio- and cerebrovascular events.

| Measure | Description | Time Frame |
|---|---|---|
| Determinants of Intima-Media Thickness (carotid and aortic) | Predictors to be examined include: Blood Pressure, BMI/body composition, Smoking, Physical Activity, Family History, Lipid and Glucose Metabolism, NAFLD, Diet, Sex, Age used as predictors in multiple regression analysis | Day 1 |
| Determinants of the Pulse-Wave Velocity [m/s] | Predictors to be examined include: Blood Pressure, BMI/body composition, Smoking, Physical Activity, Family History, Lipid and Glucose Metabolism, NAFLD, Diet, Sex, Age used as predictors in multiple regression analysis The pulse-wave velocity [m/s] is measured by using the Vicorder, an oscillometric pulse-wave measurement device. | Day 1 |
| Measure | Description | Time Frame |

| The effect of primary headache disorders on Intima-Media Thickness [µm] | Primary Headache Disorders are assessed by means of structured medical questionnaires in a physician-guided interview and classified according to the ICHD-3 Classification System. Differences in terms of vessel wall thickness [µm], measured ultrasonographically, are compared across the different primary headache diagnoses. | Day 1 |

| The effect of primary headache disorders on Pulse-Wave Velocity [m/s] | Primary Headache Disorders are assessed by means of structured medical questionnaires in a physician-guided interview and classified according to the ICHD-3 Classification System. Differences in terms of pulse-wave velocity [m/s], measured with use of an oscillometric pulse-wave measurement device, are compared across the different primary headache diagnoses. | Day 1 |
| The effect of the gut microbiome on the cardiovascular risk profile. | Structure and composition of the Microbiom using 16S metagenomics and shotgun metagenomics and are evaluate for their interrelationship with cardiovascular risk parameters (such as hypertension, smoking, dyslipidemia, impaired glucose tolerance, overweight/obesity, sedentary lifestyle, unhealthy dietary habits, ...). Where appropriate additional functional insight will be obtained by metabolomics (gas chromatography and MR chromatography). | Day 1 |
