Measures Of Association Used In Analytical Epidemiology
Measures Of Association Is Used In Analytical Epidemiology To Identify
Measures of association is used in analytical epidemiology to identify the connection of being exposure and disease outcome. Included in the measures are relative risk, absolute risk reduction, attributable risk, and odds ratio. In your judgement, what are the relevancy/principles do these measures add to public health decision makers? Select one measure of association, and use it as an example.

Understanding measures of association is fundamental for public health professionals aiming to interpret epidemiological research and make informed decisions to improve population health. These measures quantify the relationship between exposure factors and health outcomes, guiding policymakers in prioritizing interventions and allocating resources effectively. Among the various measures, relative risk (RR) is particularly vital in cohort studies where the incidence of disease in exposed and unexposed groups can be directly compared.
Relative risk signifies how much more (or less) likely an exposed group is to develop a disease compared to an unexposed group. Its value indicates the strength of the association; an RR of 1 suggests no association, while values above 1 indicate increased risk, and values below 1 suggest a protective effect (Merrill, 2017). For public health decision makers, RR provides critical insights into the magnitude of risk posed by specific exposures, enabling targeted interventions.
Specifically, RR informs risk communication, policymaking, and prevention strategies. For example, if a study reports an RR of 2 for lung cancer among smokers versus non-smokers, it implies that smokers are twice as likely to develop lung cancer as non-smokers. This compelling evidence can lead to policies that focus on smoking cessation programs, taxation, and public awareness campaigns. Moreover, RR assists in evaluating the potential public health impact of reducing exposure; a high RR underscores urgent intervention.
Additionally, RR supports resource allocation by identifying high-risk exposures with significant impact. It also helps in assessing the effectiveness of intervention programs over time. Despite its utility, RR has limitations; its applicability is mainly within cohort studies, and it does not measure the actual population burden without considering exposure prevalence. Nonetheless, RR remains invaluable for establishing causal relationships and prioritizing health interventions.
In conclusion, relative risk, as a measure of association, offers public health decision makers a quantitative basis for understanding risk factors associated with disease. Its capacity to demonstrate the strength of associations helps in designing effective prevention strategies, allocating resources efficiently, and ultimately reducing disease burden.
