NCT01605123

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • cardiovascular dysfunction

    Assessment of endothelial function, carotid intima media thickness, blood pressure, echocardiography, exercise capacity, insulin sensitivity by oGTT, serum lipids

    7 years

Study Arms (4)

Lean children

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;

Obese children

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 Exercise Group

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.

Classical Lifestyle Intervention

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.
