most cost effective form of healthcare
ex: education, exerside, diet
secondary prevention
designed to identify and treat asymptomatic persons who have already
developed risk factors but the disease is not clinically apparent

,related complications

Prevalence
estimate of how many people have a specific disease, condition or risk factor
AT A GIVEN POINT IN TIME
prevalence rates DO NOT CHANGE from year to year until there is a new
survey
,Government agencies periodically conduct health examination surveys. Rates
for specific diseases are calculated from those surveys. These rates are
applied as the population changes for several years until a new health
examination survey is done and new rates are established.
Incidence
an estimate of how many NEW cases (or rate of development) of a disease
develop in a population over or in a given time period.
For some diseases, new and recurrent attacks or cases are combined. The
incidence of a cardiovascular disease in the US is estimated by multiplying
the incidence rates reported in community or hospital based studies by the
US population.
the rates ARE NOT computed annually, they change only when new data is
available.
Mortality
refers to the incidence of death in a population.
mortality figures are the most accurate data available for assessing the
impact of CV diseases and stroke.
These data are compiled from death certificated and are sent by the state
health agencies to the National Center for Health Statistics.
There the information is verified and tabulated by cause of death, age, sex,
race, ethnicity, for the US and each state.
Morbidity
refers to the incidence of ill health in a population.
, Data is collected by organizations such as the CDC and WHO by gender, area,
age, and other demographics.
Morbity scores or predicted morbidity are assigned to ill patients with the
help of systems such as Glasgow coma scale.
Death rate
a ratio between mortality and population. Nation death rates are computed
per 100,000 population. Dividing the mortality by the population results in a
crude death rate.
Vaccines are generally NOT contraindicated with mild acute illnesses with low
grade fevers, antibiotic therapy, soreness/redness at the site and family
history of adverse affects.
