Participant Flow

Due to practical circumstances, it was not possible to conduct baseline measurements before randomization. Consequently, 9 participants dropped out before baseline measurements toke place.

Measure
Intervention Camp
Children's behavior were controlled each week day for six weeks, and participated in three hours of physical activity every day. Intervention camp: The children were participating in a 6 week day camp. The camp contained social activities, physical activity training, usual school classes and health education. All meals (healthy food) were consumed during the camp day. A subsequent 46 weeks family based intervention took place after the camp was completed.
Standard Intervention
Standard intervention: The children were offered a weekly 1 hour training and/or activity session during six weeks. This includes one session where the parents also were invited to get information about diet and exercise.

To assess motor skills, the Movement Assesment Battery for Children 2 (Movement ABC-2) test for 11-16 year olds was applied. The battery allows for recording a number of different aspects of a child's movement skills in a systematic way. In this study we only used the quantitative part of the test (it also includes a qualitative part). This includes 3 tests for hand skills (fine motor skills), 2 tests for throwing and catching balls, and 3 tests for balance skills. Each subtest returns a score, which is summarized and then equivalent to a percentile score (based on norm data from a standard population in a table from the Movement ABC-2 compendium). The percentile score is reported as the overall motor skills. The scale is from 0.1 to 99.9 (normal distributed with an average of 50) and higher scores mean better motor skills.

The CVD risk factor is the mutual presence of five different health outcomes based on the Metabolic Syndrome. It is calculated by creating a composite risk score (mean of z-scores) of: 1) Insulin resistance (Homeostatic Model Assessment for Insulin Resistance (HOMA-IR)), 2) Systolic blood pressure, 3) triglyceride, 4) total cholesterol/HDL ratio, 5) Abdominal fatness (by Dual-energy X-ray absorptiometry (DXA)), and 6) aerobic fitness.
