Transcript

  • 1. SHARI ELIUNIVERSITY OF TORONTOHistory of Health
  • 2. History of Health  What are the key factors which explain the mortality transition in the West over the last 300 years?   PublicHealth Interventions   Improvements in the standard of living   Role of Education  Lessons which can be applied to developing countries today?
  • 3. Crude Death Rate of Infectious Diseases
  • 4. Public Health Interventions  Acceptance of the Germ Theory of Disease in the 1890s  New investments in collective goods - paid for by taxes - such as water treatment   In 1900, 44% of deaths in major cities are from infectious diseases (18% in 1936), 25% from waterborne diseases   Cutler and Miller (2005) find that the chlorination and filtration of water accounts for ½ the mortality reduction between 1900 and 1936 in the US
  • 5. Other public health interventions  Public Health Campaigns:   washing hands & food   breast-feeding & boiling milk  Large-scale interventions:   sewage treatment and chlorination   regulations for milk/meat   garbage collection
  • 6. Increases in the Standard of Living  Many of the public health campaigns/interventions of the early 20th century were targeted at urban populations  But we see great gains in life expectancy outside of urban areas too   1900-1940: Life expectancy rises from 47 to 63 in the US  Both rural and urban populations experience great improvements in the standard of living in this period
  • 7. Increases in GDP per capita
  • 8. Native Born US Male Height
  • 9. Role of Increased Income  Eli (2012) looks at effect of increases in Civil War veteran pensions on health status between 1893 and 1906  Finding: Extra $1 of monthly pension income - 9% of the average veteran’s monthly pension - lowers probability of contracting a respiratory illness by 19%   Equivalent to a decline in the hazard rate from 9 in 1000 to 7 in 1000  Extra $1 of monthly pension income lowers the hazard rate of dying from any illness from 28 in 1000 to 20 in 1000
  • 10. Why such large effects?  With extra income, one can have improve his   Nutrition   Living Conditions   Working Conditions  One can also work less or retire early
  • 11. Choices regarding health  Large-scale public health interventions run by city governments are the result of new information and technology on health  But improvements in health that come from increases in socioeconomic status are most likely not the result of individuals making conscious investments in their health
  • 12. Role of Education  Part of the benefit of education is simply in gathering children in the same place each day (“High School Movement” 1910 – 1940)   Good opportunities for disseminating information on the benefits of hand-washing, etc. as well as for mass vaccinations   Example: Rockefeller Sanitation Commission’s de-worming campaign in the U.S. South, 1905 – 1910   RSC surveyed infection rates in affected areas and found that an avg. of 40% of school-aged children suffered from hookworm infection   Sponsored treatment dispensaries that traveled these areas providing de-worming medications and educating local physicians and the public about prevention   Great effects on school enrollment, literacy and earnings in adulthood
  • 13. Conclusions   U.S. Public Health Interventions which were beneficial were ones   Imposed by local government (water treatment)   Very specific targets (de-worming)   Much of the gains to life expectancy were not the result of individuals making better decisions with regard to their health   Instead,better health was a byproduct of increases in SES or the result of public health interventions
