    Study Notes

    Definition of Epidemiology

    • Epidemiology is the study of how diseases affect the health and illness of populations.
    • It investigates the distribution, patterns, and determinants of health-related events in specific populations.

    Bradford Hill Criteria

    • A set of principles used to establish causal relationships between a presumed cause and an observed effect.
    • The criteria include factors such as strength, consistency, specificity, temporality, biological gradient, plausibility, coherence, experiment, and analogy.
    • These criteria guide researchers in assessing whether observed associations might indicate causation.

    Causality in Epidemiology

    • Refers to the relationship between one event (cause) and another event (effect).
    • Essential for understanding the origins and propagation of diseases, aiding in prevention and control measures.

    Number of Criteria in Bradford Hill Criteria

    • There are nine criteria in total within the Bradford Hill framework.

    Key Focus of Epidemiology

    • One of the primary focuses is to identify risk factors for disease and targets for preventive healthcare.
    • It aims to understand the factors that lead to health inequalities among various population groups.
