Collecting data on children's health involves various methods and sources:
- Surveillance Systems: National and local health departments often have surveillance systems to monitor diseases and health behaviors in children. - Cohort Studies: Longitudinal studies that follow children over time provide valuable data on health outcomes and risk factors. - Cross-Sectional Surveys: Surveys such as the National Health and Nutrition Examination Survey (NHANES) collect data on a wide range of health indicators. - Administrative Data: Health records from hospitals, clinics, and insurance databases are used to study health trends and outcomes.
