These estimates include the influence of other extraneous variables, such as confounders. Confounding is often considered a type of bias, but it is a real relationship that requires an adjustment in the study design or analysis. Understanding how to identify confounding is important as most associations have multiple causal factors. Recognizing if a study adjusted for the appropriate confounding variables is important to determine the validity of the association. To assist your proficiency with the concept of confounding, and how it ultimately affects public health, this practice assignment has been provided. pub 540 Topic 4: Study Designs I.

Describe the characteristics and design of a cohort study. Based on a disease or health condition identified from the “2020 LHI Topics” on the Healthy People 2020 website, or an article from the GCU library, discuss a real example of a cohort study (include the link to the article in your post to the forum) pub 540 Topic 4: Study Designs I. Include the participants, exposures or treatment groups, timeframe, and outcomes that were measured.
