SEPAGES is a new type of longitudinal couple-child cohort with repeated clinical examinations during pregnancy and childhood, extensive collection of repeated biological samples from both parents and the child, use of new technologies to assess exposure to air pollution (GPS, personal dosimeter etc.) Throughout the study (during pregnancy and the first years of the child’s life), clinical examination and many biological tests (urine, blood, hair) are performed. Exposure to different environmental factors are made several times during pregnancy and the first years of the child’s life thanks to personal dosimeters, GPS and accelerometers. During labor and childbirth a number of samples are taken (placenta, tissues, blood, urines, hair, meconium and breast milk). Finally, during the study a number of evaluation questionnaires are given to volunteers via a computer platform in order to have a better understanding of the environment in which they are living.
