Pidemiological Studies: Critical Review

Current Epidemiological Studies: Critical Review

Select three current epidemiological studies regarding risk factors that are associated with any health problem. You can also use the following websites to search for studies as they are often used as the major sources of information for health research and often report on the most current health problems affecting the United States and global populations:
a?U.S. National Library of Medicine National Institutes of Health
/)
a?What were the types of risk factors studied in your chosen articles? (For example, environmental, socio-economic, behavioral, etc.)
a?Which study design was used for this study? Why do you think the researchers chose this specific study design? Provide examples from your research.
a?What are the proximate or underlying determinants of risk factors that are associated with any health problem for each study?

Answer the questions posted below in the Template for Assessment of Causality for Reviewing Epidemiological Studies, for each study. You should number each study, list the title, and state each question in the format it appears in the template.


Support your responses with examples.

Cite any sources in APA format.

Study design
Study population
Main result A. Description of the evidence
What was the exposure or intervention?
What was the outcome?
What was the study design?
What was the study population?
What was the main result?





Internal Validity
Observation bias
Recall bias
Confounding
Chance B. Internal Validity (non-causal factors)
Are the results likely to be affected by observation bias?
Are results likely to be affected by recall bias?
Are the results likely be affected by confounding (list which ones)?
Are the results likely to be affected by chance?
Generalizability
Eligible population
Source population
Other population C. External validitya Generalization of results
Can the study results be applied to the eligible population?
Can the study results be applied to the source population?
Can the study results be applied to other relevant populations?
