HLTB16H3 Lecture Notes - Lecture 4: Cardiovascular Disease, Cohort Study, Framingham Heart Study
Document Summary
Evidence based public health: research, surveillance and epidemiology and community consultation: epidemiology study designs. Types of health measures: aggregate measures: counts of individuals that can be aggregated. Measure health outcomes of individuals: environmental measures: factors external to the individual. Ex: air pollution, water quality, toxins in soil/food: global measures: factors with no analogue at the individual level. Affect population but can"t be seen at an individual level. Incidence: rate of new cases of disease in a defined population at risk over a specified period of time. Important to measure because it can show the rate of diseases and helps prevent onset of disease: also important because they can allocate money towards that disease, understanding new disease gives us a sense of causes. Prevalence: total number of cases of disease existing in a defined population at a specific time, tells us about the total burden on disease existing already, tells us about the resources that we need.
