Population-Based Research

Population-based research slides by Katrina Walsemann

A population-based approach to ADRD is crucial to understanding the role that sociocultural, behavioral, and environmental determinants play in the production and maintenance of ADRD disparities. Population-based research uses probability samples, such as HRS, that can be used to make inferences to populations of interest. The most important aspect of population-based research is external validity. Moreover, this approach emphasizes effective data management, analysis, and interpretation of theoretically informed research questions pertinent to ADRD. Population-based research is supported by the Analysis Core via the Biostatistics Unit (BSU) and the Population Science Unit (PSU).
