Review the different types of observational study designs presented in the Learning Resources: ecologic, cross-sectional, case-control, and cohort

Review the different types of observational study designs presented in the Learning Resources: ecologic, cross-sectional, case-control, and cohort.
Carefully examine the characteristics, strengths, and limitations of each design.
Consider when it is appropriate to use each of the observational study designs.
Consider how using observational study designs can lead to improvements in population health.
By Day 1 of this week, you should have received a communication from your Instructor assigning you to a small group to review two specific articles. Review the two articles your group was assigned, with a critical eye toward the researchers’ use of study design and their selected methods. Although several students will be assigned the same articles, this is NOT a group project; please submit your Discussion posts individually. You will then have the opportunity to discuss and share your thoughts with your colleagues.
BY DAY 3 OF WEEK 3
In your assigned group area:

Post a brief description of the two studies you were assigned, with a particular focus on the study design and methods. Then:

Describe at least one strength and one limitation of each study’s design.
Identify the population, data sources, and epidemiologic measures of association that the authors used.
Finally, share your insights about the appropriateness of the design for the study. Do you agree with the researchers’ choice of design?
Do you agree with the researchers’ conclusions? Justify your reasoning.
