CArdioMetabolic Prevention in Adolescents

The aim of the CArdioMetabolic Prevention (CAMP) pilot study is to investigate the effect of a group intervention on lifestyle in adolescents and on at least one adult family member. This will be followed by telemedicine tools for 12-week-time period. A face-to-face group intervention addressing nutrition, physical activity and well being together with an assessment of anthropometry parameters, body composition, questionnaires, blood and stool sampling will be done before and after 12 weeks of telemedicine. The study aims to investigate: * the effect of 12-week intervention on body weight, anthropometry parameters and cardiometabolic markers in comparison to the conventionally led obesity clinic for adolescents * the compliance with telemedicine tools that will focus on the support of balance nutrition, physical activity (evaluation of daily steps through smart bands) and family well being in regards to the effect on anthropometry and laboratory parameters * the effect of the intervention on data from questionnaires (eating disorders, quality of life, psychological health) before and after the intervention * data analysis of family members with respect to theirs offspring
