UNIT ONE Health- complete physical, mental, and social well-being and not just the infirmity disease- pathological process having characteristic set of signs and symptoms symptom- abnormal feeling thats subjective, can’t be measured sign- medical fact that can be measured with exams acute- brief chronic- long lasting, non-communicable, degenerative, unclear etiology, multiple risk factors, long latency period then prolonged clinical course, doesn’t resolve randomly, associated with impairment and disability, unlikely “complete” care. (flu vs heart disease) stages: 1. disease free 2. asymptomatic biological changes 3. morbidity: illness, impairment 4. Comorbidity: simultaneous and complex interactions of multiple diseases 5. mortality: death modifiable vs non-modifiable risk factors bad habits vs genetics and physiologic factors epidemiology: study of the control of health and disease in a population What causes disease? • strength of association: the stronger of the better, doesn’t prove it example: hair length vs height • consistency of association in multiple pops • temporality: exposure precedes disease • biological gradient: dose response • plausibility: does this make sense • coherence: evidence consistant with science ( a plethora of it ) • experimental evidence: control of cofounding variables (smoke in a bar) incidence rate: number of new cases each year in a specific population prevalence rate: number of total cases mortality: # of deaths its important to track trends!! challenges in tracking: Poverty level, crowded housing, poor education, exposure to hazardous environment, racial discrimination, no access to health care analysis types—— 1. person:age, gender, ethnicity 2. place: area in region 3. time: years, decades
