Collaborator German Research Foundation
Start date April 2007
Trial size 200 participants
Trial identifier NCT01605123, KFO152/SFB1052-C5


The investigators hypothesize that cardiovascular and metabolic alterations due to obesity already manifest at childhood age.

To identify these alterations and risk factors, the investigators have established a cohort of 177 healthy obese and lean control children, age ranging from 6y to 18y, for evaluation of cardiovascular and metabolic parameters, as well as quantification of biomarkers of obesity and inflammation. Follow-up analyses are planned after 2 years (completed) and additionally after 5, 7 and 9 years.

In addition, the investigators will assess the effects of increased physical activity and exercise on cardiovascular function.

Study Design

Observational model case control
Time perspective prospective
n=100 (anticipated), n=70 currently Age: 6-25 years BMI-SDS: -1.88 to +1.23 , currently -0.25±0.77; Height-SDS: > - 2 SDS, currently 0.03±1.07;
n=106 Age: 6-25 years BMI-SDS: >1.23 , currently 2.41±0.52; Height-SDS: > - 2 SDS, currently 0.80±1.18;
Obese children will engage in increased physical activity (one to two lessons per week) at 40-60 and 60-80% of maximal exercise capacity (n=50 each anticipated). Within the frame of the study we will assess the effect of the exercise on cardiovascular outcomes.
Obese children will receive a classical lifestyle intervention, including dietary, activity and psychosocial counselling (n=50 anticipated). Within the frame of the study we will assess the effect of the exercise on cardiovascular outcomes.

Primary Outcomes
