Study Notes
Introduction to Epidemiology
- Epidemiology aims to improve population health.
- This course introduces basic epidemiological principles and methods.
Historical Context
- Epidemiology's roots lie in Hippocrates' observations (over 2000 years ago) of environmental influences on disease.
- 19th century saw considerable measurement of disease distribution in human populations.
- John Snow's study linked London cholera to specific water sources.
- Snow's research broadened investigation of various (physical, chemical, biological, sociological, and political) factors affecting health.
Definition and Scope
- Definition: Epidemiology studies the distribution and determinants of health-related states/events in populations, applying this knowledge to prevention/control.
- Epidemiologists study death, illness, disability, positive health, and improving health.
- "Disease" encompasses negative health changes (injuries, mental health).
- Scope: Epidemiological studies focus on defined populations (like patients or workers). Often involves specific areas (and countries) or time periods, subdivided by demographics.
Epidemiology and Public Health
- Public health involves collective efforts for improved population health.
- Epidemiology is a crucial tool for achieving public health goals.
- Early epidemiology focused on communicable diseases and prevention.
- Today, epidemiology is a central medical science for improving population health, particularly in disadvantaged groups.
Causation of Disease
- Most diseases result from interactions of genetics and environment and personal behaviors (which epidemiology studies).
- Environment includes biological, chemical, physical, psychological, economic, or cultural factors.
Natural History of Disease
- Epidemiology examines disease progression and outcomes in individuals and groups.
Health Status of Populations
- Epidemiology describes population health status.
- Understanding disease burden in populations informs resource allocation for prevention and care.
- Environmental and occupational epidemiology focus on specific populations exposed to specific environments.
Evaluating Interventions
- Epidemiology evaluates health service effectiveness (e.g., hospital stays, blood pressure treatment, sanitation, reducing lead).
- Other applications of epidemiology have expanded.
Achievements in Epidemiology
- Smallpox Eradication: Epidemiology was critical, providing data on distribution, transmission, and control measures.
- Methyl Mercury Poisoning: Minamata, Japan, case study of environmental pollution.
- Tobacco, Asbestos, and Lung Cancer: Early epidemiological studies linked smoking to lung cancer, also demonstrating effects of asbestos exposure and pollution.
- Iodine Deficiency: Iodized salt implementation improved health in regions with chronic iodine deficiency.
Important Terms
- Endemic: A disease's consistent presence in a particular geographic area.
- Epidemic: An unexpected increase in disease cases in a specific area.
- Pandemic: Disease spread across multiple countries or continents.
