Ch. 3 (health promotion & disease prevention) Flashcards
Study of pattern of disease in a population
Epidemiology
New cases of a condition that occur during a specified period of time
Incidence
The total number of people affected by a given condition at a point in time or during a period of time
Prevalence
The incidence of death in a given population during a particular time period. It is calculated by dividing the number of deaths in a population by the total population.
Mortality rate
The incidence of illness in a given population during a particular time period. It is calculated in a similar manner to mortality rate.
Morbidity rate
Level of Prevention: Reducing exposure to a risk factor that may lead to the disease
primary prevention
primary prevention examples (4):
- Healthy nutrition (preventing heart disease and cancer)
- Regular physical activity (preventing heart disease and other diseases)
- Cessation of smoking (preventing lung cancer and other diseases)
- Safe sexual practices (preventing sexually transmitted infections)
Level of Prevention: Early detection and prompt treatment of disease
secondary prevention
secondary prevention examples (4):
- Screening tools such as mammography
- Pap smears, and HPV testing (find cancer early)
- Prompt use of medications after a disease is diagnosed
- Lifestyle behaviors to control chronic diseases that cannot be prevented (e.g., keep diabetes, asthma under control)
Level of Prevention: Takes place once a disease has advanced
tertiary prevention
tertiary prevention examples (4):
- Alleviating pain, providing comfort to a cancer patient
- Halting progression of an illness
- Limiting disability after a serious injury
- Restoring function through rehabilitation after a person has had a stroke
T/F: Most health care in the U.S. focuses on fixing problems, not preventing them.
