chapter 2; evidence based public health + Chapter 3; Flashcards
the first step in addressing a health problem is to describe its […] of disease, which is the occurrence of disability and death due to a disease
burden
in public health, disability is often called […] and death is called […]
morbidity
mortality
in addition to describing the burden of disease, it is important to describe what we call the […] of a disease
course
e.g. how often it occurs, how likely it is to e present currently, and what happens once it occurs
in addition to describing the burden and the course of a disease or other health problem, we need to ask: what is the […] of disease
distribution
e.g. who gets the disease, where are they located, when does the disease occur,
defining the criteria they are using to measure the occurrence of the disease; is known as case […]
definition
public health professionals called epidemiologists investigate factors known as “person” and “place” to see if they can find patterns or associations in the […] of a disease. aka group associations
frequency
three basic reasons that changes in rates may be artifactual rather than real
- differences or changes in the interest in identifying the disease
- differences or changes in the ability to identify the disease
- differences or changes in the definition of the disease
group associations are established by investigations that use information on the specific individuals within the group; population […] or ecological studies
comparisons
to conduct age adjustment, epidemiologists look at the rates of the disease in each age group and also the age distribution, or the number of people in each age group in the population
yes
contributory cause can be related with cause and effect at the individual , preceding in time, and altering the effect
yes
using a chance process known as […] or random assignment, individuals are assigned to be exposed or not exposed to the potential “cause”
randomization
[…] criteria, or ancillary criteria, that we can use to help us establish the existence of contributory cause
supportive
efficacy implies that an […] works, that is, it increases positive outcomes or benefits in the study group compared to the control group being investigated
intervention
the […] of the relationship implies that we are interested in knowing how closely related the risk factor is to the disease
strength
biological plausibility implies that we can explain the occurrence of disease based upon known and accepted biological mechanisms
yes
evidence based recommendations are built upon the evidence from studies of […]
interventions
evidence based recommendations are based upon two types of criteria: the [..]of the evidence and the magnitude of the [..]
quality
impact
well conducted [..] [..] trials that fully address the health problem are considered the highest quality evidence
randomized controlled
the quality of the evidence also includes determining whether the data collected during an intervention are relevant to their use in a particular […] or […]
population
setting
poor quality evidence implies that there are fatal flaws in the evidence and […] cannot be made
recommendations
the magnitude of the impact is the benefits minus the harms, or the “net benefits”
yes
why?
- due to evidence based recommendations taking into account the potential benefits of an intervention, as well as the potential harms
primary interventions take place […] the onset of the disease. they aim to […] the disease from occurring
before
prevent
secondary interventions occur […] the development of a disease or risk factor, but […] symptoms appear. they are aimed at early detection of disease or reducing […] factors while the individual is asymptomatic
after
before
risk
tertiary interventions occur after the initial occurrence of symptoms, but before […] disability . they aim to prevent irreversible […] of the disease
