Question 1. Which of the three levels of planned prevention and control do you think is the most helpful when conducting your research? Support your reasoning.

Question 2. Let's discuss the strengths and weaknesses of observational study designs. If you were responsible for identifying the cause of a new disease that researchers know little about, describe which study design you would use, and explain why. Respond to another student's choice of study, and identify whether you agree or disagree, and explain why.

Question 3. Select an experimental study on a topic that is of interest in your local or surrounding area (provide a link/URL to your selected study). How did the study results affect your community, state, or family? Do you think the results could apply to any area or family?

Question 4. It is important to reduce bias and confounding in research to obtain valid results. If you were the epidemiologist conducting research on the risk of stroke among women with varying numbers of children, what possible bias and confounding could you anticipate, and how would you control them?

Question 5. What do you think could be the worst ethical scenario that could arise during epidemiologic research? Briefly describe your scenario, and propose a possible solution to it. Respond to at least one peer's suggested scenario and solution.

Question 6. Now that you have a good idea of what causal relationships are and how they are determined, consider the scenario below.

You are an epidemiologist who is tasked with determining if there is an association between caffeine intake of pregnant women and lower fetal weight. Using Hill's guidelines for causality, discuss your decision of whether or not these factors have a causal relationship
