What term is the study of distribution and determinants of health-related states or events in specified populations?

• A. Etiology
• B. Epidemiology
• C. Epidemic
• D. Pandemic

Answer: (B)

Epidemiology is the study of the distribution and determinants of health-related states or events in specified populations. It describes how often diseases occur and who they affect across different groups, places, and times, and it investigates the factors that influence those patterns—the determinants—to identify risk factors and guide prevention and control efforts. By analyzing patterns of disease, researchers can quantify frequency with measures like incidence and prevalence and explore associations between exposures and outcomes to understand what influences health in a population. Etiology focuses on causes and mechanisms of disease at a more individual level, rather than on population patterns. Epidemic and pandemic refer to specific outbreak events, not the field of study itself.
