The COPENHAGEN Puberty Study is a combined cross sectional and longitudinal study of healthy Danish children.
Cross- sectional cohort
All children at randomly selected schools in Copenhagen were invited (6203 children). Of these, 1864 (1097 girls and 767 boys, age 5.6-20 years) accepted to participate, resulting in an overall participation rate of 30%. These children went through a thorough clinical examination, delivered urine samples and had blood samples taken.
209 healthy Danish children (108 girls), were examined and blood samples were drawn every 6 months. In July 2011, the mean (range) number of examinations per child was 7 (2-10).
More details about the clinical examinations, samples collected, clinical biochemistry and analytical chemistry carried out until now can be found HERE.
The study was approved by ethical committees of the Capital Region (RegionH) and in accordance with the Helsinki II declaration. All children and their parents gave informed consent to participate in the study.
