How is Data Collected in Epidemiological Research?
Data collection methods in epidemiological research can vary widely depending on the study design and objectives. Common methods include:
Surveys and Questionnaires: These are widely used to collect data on health behaviors, exposures, and outcomes. Medical Records: Accessing patient records can provide detailed information on diagnoses, treatments, and outcomes. Laboratory Tests: These are used to obtain objective measurements of health status, such as blood tests or genetic screening. Environmental Monitoring: This involves measuring environmental exposures, such as air or water quality, to assess their impact on health.
