Question

Quizplus · Accepted Answer

Ecological-level studies are those that use countries or cultures as the unit of analysis to examine how social, economic, or political factors impact health outcomes at a societal level. These studies typically use data from national surveys or databases to compare health outcomes across different countries or cultures. In contrast, individual-level studies focus on the health outcomes of individual people, and may use data from surveys, clinical trials, or other sources to examine individual behaviors, risk factors, or treatments for specific health conditions. Hypothesis-testing studies and linkage studies can be conducted at either the individual or ecological level, depending on the research question and the data available.
