Age
2 Years to 9 Years
Inclusion criteria
Inclusion criteria: 1. At the baseline survey (T0) all children, boys and girls, 2 - 9.9 years of age, attending the participating kindergartens and schools of the selected intervention and control areas in the 8 survey countries were eligible as participants. These criteria were extended to the Polish survey in 2014. 2. At the second wave of examinations (T1) all children who participated in T0 plus their classmates were invited to participate. 3. At the third wave (T3) all children who had participated either at T0 or T1 (index children) were re-invited together with their siblings in the age range 2-15 years, and both their parents. 4. Study subjects had to be residents of the selected control or intervention regions at T0. 5. Participant inclusion required that parents gave written informed consent for their children and in T3 also for themselves. Additionally, children from the age of 12 years onwards also had to give written informed consent.
Exclusion criteria
Exclusion criteria: 1. Children outside the defined age rage 2. Children not living in the study regions at T0
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Weight based on the age and sex specific BMI cutoffs were measured at T0, T1, and T3 using: 1.1. BMI was calculated as weight [kg] divided by height [m] squared 1. 2. Body weight and height were objectively measured using an adapted Tanita digital scale, BC 420 MA for children =6 years and BC 418 MA for children >6 years (weight) and a Seca 225 stadiometer (height) 3. Quality of the diet was measured using a healthy diet score and propensity scores based on a semi-quantitative food frequency questionnaire 4. Bone stiffness was measured by calcaneal ultrasonography (Lunar Achilles Insight) in in a sub-sample 5. Diet was measured using self-reported questionnaires (parents reported for their children at T0 and T1, and for children <12 at T3 ). Additionally, dietary assessment was conducted by a computer-based 24-hour dietary recall which was web-based in T3 6. Physical activity was measured using self-reported questionnaires and objectively measured using accelerometry (ActiTrainer or GT1M at T0 and T1 and ActiGraph GT3x at T3; Actigraph, LLC) 7. Sleep was measured using self-reported questionnaires (parents reported for their children at T0 and T1, and for children <12 at T3), and objectively measured using accelerometry in a subgroup at T3 (ActiTrainer or GT1M; Actigraph, LLC) 8. Family life was measured using self-reported questionnaires (parents reported for children below the age of 12) 9. Well-being was measured using self-reported questionnaires (parents reported for children below the age of 12) 10. Metabolic and nutritional biomarkers were measured using fasting blood and urine samples 11. Sensory taste perception was measured using questionnaire and by standard sensory tests in a subsample of children | — |

|---|---|
| 1. Waist circumference was measured using a Seca 200 tape at the 3 time points (T0-T3) 2. Fat mass index and free fat mass index were calculated by skinfold thickness (subscapular, triceps and biceps) using Holtain Tanner/Whitehouse skinfold calipers and by bioelectrical impedance analysis using a digital TANITA BC 420 SMA scale at T0-T3 3. Blood pressure was measured using an automatic sphygmomanometer (WelchAllyn) at T0-T3 4. Metabolic syndrome at T1. This is calculated using a z-score standardisation to calculate a continuous score combining the MetS components (waist circumference, blood pressure, dyslipidaemia and hyperglycaemia). Three widely accepted definitions of the paediatric metabolic syndrome (MetS) are applied and suggested a new definition to guide paediatricians in decisions about close monitoring or even intervention (values of at least three of the MetS components exceeding the 90th or 95th percentile, respectively). An online tool was developed to assist paediatricians when assessing the risk of metabolic syndrome in children aged 3-10 years. This tool and details on the MetS score can be found here: https://www.bips-institut.de/en/research/software/mets-score.html 5. Coordination was measured using physical fitness tests at T0 and T1 6. Motor fitness was measured using physical fitness tests derived from the EUROFIT test battery at T0 and T1 (Eurofit, (1993), Eurofit Tests of Physical Fitness, 2nd Edition, Strasbourg) 7. Cardiorespiratory fitness was measured using physical fitness tests derived from the EUROFIT test battery at T0 and T1 (Eurofit, (1993), Eurofit Tests of Physical Fitness, 2nd Edition, Strasbourg) 8. Handgrip strength was measured using a digital hand dynamometer TKK 5401 at T0 and T1 9. Built environment (regard to food outlets and opportunities for physical activities) was assessed by using objective data from geographic information system (GIS) at T0 and T3 in 2 study centres | — |
