I need these questions answered in 150 words each with individual references UNIT 3 DQ1 Differentiate between bias and confounding. Discuss the criteria necessary to establish a factor as a confounder and provide an example applying these criteria. What is one way to adjust for a confounding relationship in the study design or the analysis?
DQ2 Explain the two major types of bias. Identify a peer-reviewed epidemiology article that discusses potential issues with bias as a limitation and discuss what could have been done to minimize the bias (exclude articles that combine multiple studies such as meta-analysis and systemic review articles). What are the implications of making inferences based on data with bias? Include a link to the article in your reference.

Discuss the limitations of using questionnaires for determining exposure status and provide examples of alternative strategies for collecting this information in a case-control study. DQ2 Discuss the strengths and weaknesses of cross-sectional studies and examples of how they can be descriptive or analytic study designs.

Discuss the four types of causal relationships and use an example not listed in the textbook to describe each relationship. DQ2 Explain the difference between relative risk, attributable risk, and population attributable risk. Provide an example (not from the textbook) of how each type of risk is used in epidemiology. How would you propose using population attributable risk to advocate for a health policy or intervention relative to your health interest?

URL: https://www.youtube.com/watch?v=ITi0SxmQTO8 UNIT 7 DQ1 Epidemiological methods are used in a variety of public health areas (including infectious disease, chronic disease, and social health) and settings (including the community, schools, and the workplace). Epidemiological methods are used to assess, describe, analyze, and make comparisons of populations to inform evidence-based practices, policies, and interventions. Propose a study based on the methods you have learned thus far designed to investigate an association within one of the public health areas listed (infectious disease, chronic disease, or social health) and the methods you would apply. Discuss and define the risk factor or exposure that is being assessed, the method of comparison that is used, and the setting or situation (community, school, workplace, etc.) your study would look to address. Consider the concepts of causal inference, measures of association, and study design. DQ2 Race is often used as a descriptor of disease burden and helps us to determine where health disparities exist in order to address them, which is important. It is helpful to differentiate between race as a descriptor and race as a risk factor. Think about institutional racism and its influence on health. Consider the factors related to race and ethnicity that might be influencing disease status more than the genetics of race when answering this discussion question. Consider the following statement: Race is not a risk factor and should not be used in public health data collection. Discuss the ethical and public health implications of this statement. When might collecting data on race perpetuate institutional racism leading to health disparities and when is it necessary to improve public health? Provide support and examples for your answer. Consider ethical issues related to respect for persons, beneficence, and justice as described in The Belmont Report. STUDY MATERIALS Read Chapters 17, 19, and 20 in Gordis Epidemiology.
