  Purpose

Strong and consistent evidence have shown that overweight, including obesity, is an important risk factor for the development of cardiovascular disease (CVD) in adults. Several studies have found an association between overweight in childhood and increased risk of morbidity and mortality later in life. The prevalence of overweight in children and adolescents has increased in recent years, and consequently it is important to identify effective approaches in the prevention and treatment of overweight in young individuals.

Approaches such as resident weight loss camps have shown promising results. A residential camp setting provides an opportunity to increase and control exposure to, for instance, particular foodstuffs, beverages and physical activity opportunities. However, well-designed studies with sufficient participants are still needed on the reversal of overweight in childhood with increased focus on documenting predictors of behavior changes associated with decreases in overweight.

This study is carried through as a randomized controlled trial which investigates the effect of participating in a 6 week health promoting resident for overweight fifth grade children camp followed by 42 weeks of family support.

The study hypothesis is that participating in a 6 week resident camp and a following period of 42 weeks of child and family support will induce a reduction in body mass index (BMI). In addition it is expected that the intensity and duration intervention program is sufficient to cause changes in physiological parameters related to a reduced risk of lifestyle diseases.

Primary Outcome Measures:
  • change in Body Mass Index [ Time Frame: 6 - 4 weeks before and immediately after (over 2 weeks), and 12 months after a 6 week intervention period ] [ Designated as safety issue: No ]
    To calculate body mass index, height and weight will assessed.


Secondary Outcome Measures:
  • change in Cognitive function [ Time Frame: 6 - 4 weeks before, immediately after (over 2 weeks), and 12 months after a 6 week intervention period. ] [ Designated as safety issue: No ]
    To assess cognitive function the following test are used: The Stroop Color and word test; Trail making test (part A and B); Rey complex figure test and recognition trial; Symbol digit modalities Test; Behavior rating inventory of executive function.

  • change in Motor skills [ Time Frame: 6 - 4 weeks before, immediately after (over 2 weeks), and 12 months after a 6 week intervention period. ] [ Designated as safety issue: No ]
    To assess motor skills the Movement ABC-2 test for 11-16 year olds are applied.

  • change in Body composition [ Time Frame: 6 - 4 weeks before, immediately after (over 2 weeks), and 12 months after a 6 week intervention period. ] [ Designated as safety issue: No ]
    Measurements of fat mass and lean tissue mass will be done using dual-energy X-ray absorptiometry.

  • change in Brain-derived neurotrophic factor (BDNF) [ Time Frame: 6 - 4 weeks before, immediately after (over 2 weeks), and 12 months after a 6 week intervention period. ] [ Designated as safety issue: No ]
    The chronic level of serum brain-derived neurotrophic factor (BDNF) is assessed in fasting blood samples.

  • change in Blood pressure [ Time Frame: 6 - 4 weeks before, immediately after (over 2 weeks), and 12 months after a 6 week intervention period. ] [ Designated as safety issue: No ]
    Blood pressure will be measured in up-right sitting position after resting supine for ten minutes. A minimum of five measurements will be conducted with one minute intervals.

  • change in Subclinical atherosclerosis using B-mode ultrasound: Carotid Intima Media Thickness (IMT) and Carotid Elasticity [ Time Frame: 6 - 4 weeks before, immediately after (over 2 weeks), and 12 months after a 6 week intervention period. ] [ Designated as safety issue: No ]
    The IMT is measured on 2 sites (posterior and lateral) of the far wall 1 cm proximal to the bifurcation on both sides of the common carotid artery.

  • change in Cardio-respiratory fitness [ Time Frame: 6 - 4 weeks before, immediately after (over 2 weeks), and 12 months after a 6 week intervention period. ] [ Designated as safety issue: No ]
    Cardio-respiratory fitness will be assessed using a progressive bicycle ergometer protocol after a 5 minutes warm-up by means of indirect calorimetry (Innovision, Odense, Denmark).

  • change in Insulin [ Time Frame: 6 - 4 weeks before, immediately after (over 2 weeks), and 12 months after a 6 week intervention period. ] [ Designated as safety issue: No ]
    The level of insulin is assessed in fasting blood samples.

  • change in Glucose [ Time Frame: 6 - 4 weeks before, immediately after (over 2 weeks), and 12 months after a 6 week intervention period. ] [ Designated as safety issue: No ]
    The level of glucose is assessed in fasting blood samples.

  • change in Lipids [ Time Frame: 6 - 4 weeks before, immediately after (over 2 weeks), and 12 months after a 6 week intervention period. ] [ Designated as safety issue: No ]
    The levels of lipids are assessed in fasting blood samples.

  • change in C-Reactive Protein [ Time Frame: Last week before, first week after and 12 months after a 6 week intervention period. ] [ Designated as safety issue: No ]
    The level of c-reactive-protein is assessed in fasting blood samples.

  • change in waist/hip circumference [ Time Frame: 6 - 4 weeks before, immediately after (over 2 weeks), and 12 months after a 6 week intervention period. Finally after 48 months. ] [ Designated as safety issue: No ]
    Hip circumference will be measured at the level of the great trochanter. Waist circumference will be measured between the lower costal margin and the iliac crest.

  • change in Clustered CVD risk factor score [ Time Frame: 6 - 4 weeks before, immediately after (over 2 weeks), and 12 months after a 6 week intervention period. ] [ Designated as safety issue: No ]
    The clustered risk factors are the mutual presence of several of the above mentioned health outcomes. It is calculated by summing z-scores of metabolic syndrome risk factors

  • change in Physical strength [ Time Frame: 6 - 4 weeks before, immediately after (over 2 weeks), and 12 months after a 6 week intervention period. ] [ Designated as safety issue: No ]
    Will be measured by hand grip and Sargent vertical jump.
