The Danish National Birth Cohort (Better health in generations) was established to investigate the causal link between exposures in early life and disease later on and the possibilities for disease prevention. From 1996 to 2002 100,000 pregnancies, resulting in96,000 live born children from 92,000 unique mothers,were enrolled. Self-reports (survey data) on health,development, well-being, life-style and living conditions fo rmother and child were collected five times during pregnancy, post-partum (6 & 18 months), and at age 7,11, 14, 18 yrs. Furthermore, >600,000 bio samplesobtained twice during pregnancy and from the umbilicalcord blood1 were collected and became the backbone of the establishment of the Danish National Biobank.

The project is a multidisciplinary collaboration between sleep experts, epidemiologists, clinicians, biostatisticians and computer scientists to document the health consequences of nighttime smartphone usage. The overall aim is through different studies to add knowledge about behavioral mechanisms that may lead to nighttime smartphone usage and to document the potential health consequences of nighttime smartphone usage. Knowledge on mechanisms, barriers and consequences of nighttime smartphone usage generated in the project may be used to develop interventions aimed at reducing smartphone interrupted sleep and to prevent potential health effects.
