risk Flashcards
risk
is the likelihood of an event occurring. In health care events, we usually consider a negative consequence
arising from exposure to a hazard.
Types of risk :
1-Absolute risk
2- Relative risk
3- Attributable risk
Absolute risk:
incidence (new cases) of disease in any population
Relative risk:
ratio of the incidence rate in the group exposed to the hazard to the incidence rate in the non-exposed group, (the relative risk is the most important between them.)
Attributable risk
Difference in incidence rates between exposed and non-exposed groups.
Types of risk factors:
1- Behavioral
2- Physiological
3- Demographic
4- Environmental
5- Genetic
Behavioral risk factors
- Usually relate to ‘actions’ that the individual has chosen to take.
- They can therefore be eliminated or reduced through lifestyle or behavioral change.
examples of Behavioral risk factors
- Examples include: Smoking tobacco, Drinking alcohol, Nutritional choices, Physical inactivity, Sunlight
exposure without proper protection, No vaccinations, Unprotected sex.
Psychological risk factors
are those relating to an individual’s body or biology. They may be influenced by
a combination of genetic, lifestyle and other broad factors
Examples of Psychological risk factors
- being overweight or obese
-high blood pressure - high blood cholesterol
-high blood sugar (glucose).
Demographic risk factors
are those that relate to the overall population.
Examples of Demographic risk factors
Examples include age,
gender, occupation, income.
Environmental risk factors
are those that relate to the overall population.
examples of Environmental risk factors
-age
-gender
- occupation
-income
Genetic risk factors
based on an individual’s genes. Some diseases, such as cystic fibrosis and muscular dystrophy, come entirely from an individual’s ‘genetic make-up’. Many other diseases, such as asthma or diabetes, reflect the interaction between the genes of the individual and environmental factors. Other diseases, like sickle cell anemia are more prevalent in certain population subgroups.
