Are risk factors confounders?
A confounder is a factor that is related to the risk factor of interest and, independently of this, to outcome (disease status), but is not an intermediate factor on the causal path between the risk factor and outcome (see, for example, Rothman and Greenland [7]).
Are confounders independent risk factors for the outcome?
Conditions for Confounding to Occur 1) The additional exposure is an independent risk factor for the outcome under study, i.e., the confounding factor is associated with the outcome. 2) The distribution of the confounding factor differs among the exposure groups, i.e., it is associated with the exposure.
How do you identify independent risk factors?
In medical research, independence is generally defined in a statistical sense: a variable is called an independent risk factor if it has a significant contribution to an outcome in a statistical model that includes established risk factors.
How do you adjust for confounders?
There are various ways to modify a study design to actively exclude or control confounding variables (3) including Randomization, Restriction and Matching. In randomization the random assignment of study subjects to exposure categories to breaking any links between exposure and confounders.
What is an independent risk factor?
How are risk and protective factors related to each other?
Research has consistently shown us that: Many risk and protective factors are related to multiple community outcomes. That is, they are important factors in almost all community health and development concerns. As such, they can give you a good place to start in developing your own lists of risk and protective factors.
Which is an example of a risk factor?
Risk factors are characteristics at the biological, psychological, family, community, or cultural level that precede and are associated with a higher likelihood of negative outcomes.
What are some of the protective factors for CVD?
As we said earlier, protective factors are often the flip side of risk factors. Therefore, some of the protective factors for CVD would include low blood pressure, low cholesterol, being a non-smoker, and getting regular aerobic exercise.
Why is it important to understand the causes of problems?
There are many different and interrelated causes of problems and desired outcomes. If your organization can understand these causes, it can focus its intervention to better contribute to community improvement. This allows your organization to transform your community into the community you envision.
