An effective lifestyle intervention in overweight children: findings from a randomized controlled trial on "Obeldicks light".

Randomized controlled trials (RCT) have demonstrated the effectiveness of lifestyle interventions in obese children. However, the effectiveness of interventions for overweight, but no obese children has not been demonstrated yet by RCTs. A total of 66 overweight (BMI>90th< or =97th percentile) children (mean age 11.5+/-1.6 years, 58% females, mean BMI 23.4+/-1.5kg/m(2)) were randomized into a control group (CG) (n=32; no intervention for a duration of 6 months) or intervention group (IG) (n=34; 6 months intervention "Obeldicks light" based on physical activity, nutrition education, and behaviour counselling). BMI, waist circumference, skinfold thickness, bioimpedance analyses, blood pressure, physical activity based on questionnaires, and three-day-weighed dietary records were determined at baseline (T0) and 6 months (T1) later. Degree of overweight was calculated as BMI-SDS. Comparisons were performed on an intention-to-treat approach. The drop-out rate was 3% in IG and 16% in CG. At T1, 94% of the children in IG decreased their BMI-SDS and 24% of them were normal weight. The changes between T0 and T1 in BMI-SDS differed significantly (p<0.001) between IG and CG (CG: +0.05+/-0.19 BMI-SDS; IG: -0.26+/-0.22 BMI-SDS). Similar findings were observed for blood pressure, waist circumference, skinfold thickness, and fat mass based on bioimpedance analyses. In the IG, energy, fat and sugar intake decreased significantly between T0 and T1, while no significant changes were observed in the CG. The lifestyle intervention was associated with an improvement of dietary patterns and was effective in reducing degree of overweight, fat mass, waist circumference, and blood pressure.

An effective lifestyle intervention in overweight children: one-year follow-up after the randomized controlled trial on "Obeldicks light".

Lifestyle interventions address primarily obese children, while interventions tailored to overweight but not obese children are scarce. The effectiveness of the lifestyle intervention "Obeldicks light" based on physical activity training, nutrition education, and behavior counseling for overweight children and their parents has been demonstrated by a randomized controlled trial. Here, we present the 12 months follow-up analysis of these children after end of intervention. Degree of overweight (BMI and SDS-BMI), waist circumference, skinfold thickness, bioimpedance analyses (BIA), and blood pressure were determined in 76 overweight (BMI>90(th)≤97(th) percentile) children (mean age 11.8 ± 1.8years, 67% females, mean BMI 24.3 ± 1.9 kg/m(2)) participating in the evaluation study of "Obeldicks light" at onset of intervention (T0), end of 6 months intervention (T1), 6 months after end of intervention (T2) and 12 months after end of intervention (T3). Comparisons were performed on an intention-to-treat approach. The drop-out rate was 4% in the intervention period and additional 3% during follow-up. The children reduced significantly (p < 0.001) their SDS-BMI in the intervention period between T0 and T1 (-0.27 ± 0.23; p < 0.001). This SDS-BMI reduction remained stable at T2 (T0-T2:-0.26 ± 0.31; p < 0.001) and T3 (T0-T3:-0.26 ± 0.39; p < 0.001). SDS-BMI reductions were independent from age and gender. Body fat measured by skinfold thickness and BIA, waist circumference, and blood pressure decreased significantly in the intervention period and remained stable in the follow-up period as well. The lifestyle intervention "Obeldicks light" was effective in reducing degree of overweight, fat mass, waist circumference, and blood pressure both at end of intervention and in a 12 months follow-up period.
