    Study Notes

    Epidemiology

    • Study of the distribution and determinants of health-related events, diseases, or health-related characteristics among populations
    • Examines frequency, pattern, and causes of diseases
    • Uses statistical methods to analyze data and identify trends
    • Types of epidemiological studies:
      • Observational studies (case-control, cohort, cross-sectional)
      • Experimental studies (randomized controlled trials)

    Pathophysiology

    • Study of the changes that occur within an individual or population as a result of disease or injury
    • Examines the biological and physiological processes that occur during disease development
    • Focuses on the underlying mechanisms and processes of disease
    • Includes the study of:
      • Cellular and molecular changes
      • Organ system dysfunction
      • Physiological responses to disease

    Disease Prevention

    • Interventions aimed at preventing or reducing the incidence of disease
    • Types of disease prevention:
      • Primary prevention (e.g., vaccination, healthy lifestyle)
      • Secondary prevention (e.g., early detection, screening)
      • Tertiary prevention (e.g., treatment, rehabilitation)
    • Strategies for disease prevention:
      • Health education and promotion
      • Environmental modifications
      • Behavioral changes

    Health Promotion

    • Process of enabling individuals and communities to increase control over their health and improve their well-being
    • Focuses on promoting healthy behaviors and lifestyles
    • Strategies for health promotion:
      • Health education and awareness
      • Community-based initiatives
      • Policy and environmental changes
      • Health literacy and empowerment

    Global Health

    • Study of health issues and trends at the global level
    • Examines the impact of globalization on health and health systems
    • Focuses on:
      • Health disparities and inequities
      • Global health governance and policy
      • International health cooperation and collaboration
      • Health systems strengthening and capacity building
    • Global health challenges:
      • Infectious diseases (e.g., COVID-19, HIV/AIDS)
      • Non-communicable diseases (e.g., diabetes, cardiovascular disease)
      • Health systems and infrastructure development
