A randomized controlled trial on a multicomponent intervention for overweight school-aged children - Copenhagen,...

Area of Science:

• Pediatric Endocrinology
• Metabolic Syndrome Research
• Childhood Obesity Interventions

Background:

• Childhood obesity is a global health concern with limited understanding of controlled weight loss effects on metabolic syndrome components.
• Previous research has not extensively explored the impact of structured interventions on metabolic health in overweight children.

Purpose of the Study:

• To assess the effects of a 20-week combined exercise and diet guidance program on body mass index (BMI) in overweight children.
• To investigate secondary effects on body fat, insulin insensitivity, and other metabolic syndrome markers.

Main Methods:

• Randomized controlled trial involving overweight school children in Copenhagen.
• Intervention group received 20 weeks of diet and exercise guidance; control group did not.
• Measurements included anthropometry, dual-energy X-ray absorptiometry, oral glucose tolerance tests, pedometer step counts, and fitness tests at baseline and 20 weeks.

Main Results:

• The intervention group showed significant reductions in BMI (mean difference -2.0 kg/m2), total body mass (-4.0 kg), and fat mass (-3.3 kg) compared to controls.
• Waist circumference, hip circumference, and waist-to-height ratio (WHtR) significantly decreased in the intervention group.
• Improvements observed in plasma insulin levels and increased daily step counts (mean and minimum) in the intervention group.

Conclusions:

• A multicomponent intervention significantly improved BMI, weight, WHtR, physical activity levels (steps/day), and body fat mass in overweight children.
• The intervention demonstrated beneficial metabolic effects comparable to those seen in adults, including enhanced peripheral insulin sensitivity.
