  1. Epidemiology
    to apply epidemiologic concepts to evaluate/study the distribution and determinants of disease fequency, injury, and disability (of mortality, morbidity, injury, and disability) in human populations
  2. Descriptive Epidemiology
    Observe and Describe
  3. Analytic Epidemiology
    • Application of epidemiological statistics - ratios
    • one number/another number X constant
  4. Biostatistic
    one number/another number X constant
  5. Underlying assumption of Public Health
    Culture and diversity play a role in health - influenced by access to care, health literacy, and demographic variables
  6. Levels of Maturity
    • 1. dependence
    • 2. independence
    • 3. inter-dependence
  7. Interdependence
    Behaviors of one influence the behaviors of many
  8. Epidemiology focus
    human populations
  9. Applications of Epidemiology
    • 1. Study the etiology of diseases, disorders, and disabilities
    • 2. identify agents associated with diseases
    • 3. Assist in the development of health initiatives, services, andprograms
    • 4. prevent/protect and control diseases
  10. Magnitude
  11. Person
    Refers to demongraphics variables that influence the etiology such as age, gender, race, sex, socio-economic, and marital stats
  12. Place
    specific geographic location
  13. Time
    Specific period of time
  14. Sporadic
    • an event that occurs irregularity or haphazardly - variable time
    • Biostatistics - time series analysis - used to determine future patterns
  15. Endemic
    • the constant presence of a disease or infectious agent within a population (steady state).
    •  - generally a disease for which we have prevention
  16. Hyperendemic
    disease presents constantly at a high rate and in all parts of the population
  17. Holoendemic
    The disease is more prevalent in kids than in adults (kids infect kids).
  18. Outbreak
    • An event of acute illness thatdoes not reach pandemic or epidemic distribution
    • - confined to a small geographic location
  19. foodborne/waterborne outbreak
    2 or more cases - 1st case is endemic state
  20. Epidemic
    • the number of observed diagnosed cases in a community, state, or region is greater than expected. 
    • - expected number is endemic state
    • - break or change in trend in a geographic region
  21. pandemic
    the number of cases observed in a population is greater than expected (endemic state) in a large geographic location - country or world
