About this trial
The COPENHAGEN School Study is a combined cross-sectional and longitudinal study of healthy Danish school children. This study will by clinical examinations and withdrawal of blood samples investigate whether age of pubertal onset is continuing to decline in Denmark over the past 15 years. Furthermore, we will investigate the mechanism driving earlier onset of puberty and the long term health risks of extremely early puberty using Danish registry data
