Lecture: Intro to Epidemiology and Measures of Occurrence

• Definitions of Epidemiology
• States vs. Events
• Population
  An aggregate of people, defined by membership-defining...
  • event -> "cohort" ( closed population i.e. closed for exit)
    or
    
  • state - for duration of state -> Open population (open for exit) / dynamic / turnover
• Prevalence (of a state)
• Population-time
• Incidence ( new events in members "at risk" for the event )
  • Incidence density (momentary or average over a span of time)
  • Hazard (momentary, but more commonly used w.r.t a closed population)
  • Force of morbidity/mortality / Intensity
• Cumulative Incidence (over a span of cohort time), and associated terms
  • Risk
  • its complement: Survival proportion
• Mathematical link between Incidence Density and Cumulative Incidence
