Course of Obesity and Extreme Obesity in Adolescents

The rate of adolescent extreme obesity is rapidly rising, and impacting quality of life, psychosocial situation, and health of the affected youth. However, as few of these adolescents seek medical care, little is known about the longitudinal course of adolescent extreme obesity. In this study, the investigators aim to provide structured care for adolescents with obesity and extreme obesity over a prolonged period of time, and to gain information on the course of obesity and the success of different treatment options. The study is a subproject of the "Medical and psychosocial implications of adolescent extreme obesity - acceptance and effects of structured care", short: "Youth with Extreme obesity Study (YES)", which aims at improving the medical care and social support structures for youth with obesity and extreme obesity in Germany. Obese youth and young adults (BMI ≥ 30kg/m2) between the ages of 14 and 24.9 years (initially up to 21 years) are eligible to participate. Participants will have a physical check-up every 12 months (initially every 6 months), complete questionnaires on their health, socioeconomic status and wellbeing, and are offered blood test and diagnostic procedures to assess comorbidities. Participants are offered support and guidance for social and vocational integration. The study will evaluate and inform treatment and support options for adolescents with extreme obesity.
