The Duisburg Birth Cohort Study investigates the long-term impacts of prenatal exposures to endocrine-disrupting chemicals (EDCs) towards the development of children and adolescents. Beginning in 2000, the study includes over 200 mother-child pairs from the southern part of Duisburg city in Germany. The participants in the study were followed up at multiple time points, including at ages 12, 18, and 24 months, and annually from the age of 6-7 years until the children were 11 years old. The most recent follow-up was conducted between 2017 and 2018, when the adolescents were between 15 and 17 years old.
