Study Notes

Origins of Epidemiology

The concept of epidemiology dates back over 2000 years to Hippocrates, who noted environmental factors influence disease occurrences.
Significant progress in measuring disease distribution within specific human populations began in the 19th century, which established epidemiology as a formal discipline.

Landmark Studies

John Snow's research during a cholera outbreak in London illustrated the connection between water supply and disease risk, highlighted by his case clustering map.
Early epidemiology examined various factors including physical, chemical, biological, sociological, and political influences on health.

Advances in Disease Comparison

The late 19th and early 20th centuries popularized comparing disease rates among population subgroups, initially focusing on communicable diseases.
This methodology effectively linked environmental conditions to specific diseases and expanded to chronic noncommunicable diseases like heart disease and cancer in the latter half of the 20th century.

Modern Epidemiology

Modern epidemiology employs quantitative methods to study health-related states and inform public health strategy.
Pioneering work by Richard Doll and Andrew Hill in the 1950s established a strong link between tobacco use and lung cancer through long-term cohort studies.

Definition of Epidemiology

Epidemiology is defined as the study of health-related state distributions and determinants in specified populations, aimed at preventing and controlling health problems.

Lung Cancer Insights

Lung cancer, once rare, saw dramatic increases in incidence since the 1930s, primarily due to tobacco use.
Initial studies confirming the link between smoking and lung cancer were published in 1950, with significant case-control studies demonstrating a strong association.

Risk Factors and Statistical Evidence

The British doctors’ study showed a relative risk of 14 for lung cancer in smokers compared to non-smokers, indicating a strong causal relationship.
Other risk factors like asbestos exposure and urban air pollution also contribute notably to lung cancer cases, with their combined effects significantly increasing risks, especially for individuals exposed to both.

Focus on Injury Epidemiology

Injury epidemiology involves interdisciplinary collaboration, paying particular attention to falls among older adults, specifically hip fractures.
Hip fractures are projected to rise exponentially due to increased elderly population; they represent significant health service concerns and economic costs, being one of the leading injury diagnoses in terms of financial impact despite lower incidence rates.
