Through this effort, the registry assists the health authorities in prioritizing preventive efforts to promote better child health outcomes.Study Population: The registry includes all Danish children, however, incomplete coverage persists.Main Variables: The National Child Health Registry contains information on exposure to secondhand smoking, breastfeeding duration, and anthropometric measurements through childhood. The information in the registry is divided into three datasets: Smoking, Breastfeeding, and Measurements. Beside specific information on the three topics, all datasets include information on CPR-number, date of birth, sex, municipality, and region of residence.Database Status: The National Child Health Registry was established in 2009 and contains health information on children from all Danish municipalities, collected through routinely performed health examinations conducted by general practitioners and health nurses.Conclusion: The National Child Health Register is an asset to epidemiological and health research with nationwide information on children’s health and growth in Denmark. Due to the unique Danish Civil Registration System, it is possible to link data from the National Child Health Register to information from several other national health and social registers which enables longitudinal unambiguous follow-up.Keywords: child health, children‘s database, register-based research, Danish register, epidemiology |
