What is the Role of Epidemiology in Assessing Advertising Impact?
Epidemiologists use various methods to assess the impact of advertising on public health. Observational studies, such as cross-sectional and cohort studies, help identify associations between advertising exposure and health outcomes. Randomized controlled trials (RCTs) can provide more robust evidence by evaluating the effectiveness of specific advertising interventions in controlled settings. Surveillance systems also play a critical role in monitoring changes in health behaviors and outcomes over time, allowing for the assessment of advertising impact on a population level.
