CORE 1 Flashcards
What is Epidemiology?
the study of rates and patterns of illness, disease and injury amongst specific population groups.
Purposes of epidemiology?
monitor major causes of sickness/death, identify priority population groups, evaluate the effectiveness of prevention and treatment.
Who uses epidemiology?
researchers, health department officials, government, health practitioners
measures of epidemiology
mortality, infant mortality, morbidity, life expectancy
Mortality
number of deaths for a given cause in a population over a set period
Morbidity
patterns of illness, disease and injury that do not result in death
Infant mortality
number of deaths in the first year of life
Life expectancy
average number of years a person can expect to live at any given age
limitations of epidemiology
can be manipulated, focuses on negative aspects of health, does not focus on the quality of life, little data on impact of disease, does not say why health inequities persist
what are priority population groups
groups that do not achieve the same health outcomes in any area as the rest of the population (e.g. ATSI)
social justice principles
Equity, diversity, supportive environments
Potential for prevention and early intervention
prevention = ability to avoid the condition from occurring
early intervention = greater success of treatment if condition is identified early
Prevalence of a condition
the number of cases in the population at a given time
higher prevalence = higher priority
Costs to individual and community
money, time, mental health, independence, time off work
example: cancer is a high-cost disease, where arthritis is not
healthy ageing
the process that involves various behaviours and choices that affect health. the goal of healthy ageing is to maintain health into old age allowing contribution to workforce and society for longer
