Which factors listed below are non-causal and may distort observed findings in a health study?

How would you design a study to assess the health effects of criteria air pollution on health in Wisconsin? (5 bullet points minimum) Define your air pollutant of interest, health outcome of interest, and describe your epidemiology study design choice. List the measure of association you would use to evaluate exposure vs. health outcome. List at least one confounding variable you’d want to include and explain why it should be included. Provide at least one strength and one limitation of your exposure data. Provide at least one strength and one limitation of your health data.

A large, prospective cohort study tracks a population over 20 years to investigate the link between long-term exposure to fine particulate matter (PM2.5) and the incidence of chronic obstructive pulmonary disease (COPD). The study produces the following findings: Compared to individuals in the lowest category of PM2.5 exposure, those in the highest category have a threefold higher risk of developing COPD. The risk of COPD increases steadily and progressively with each higher category of PM2.5 exposure. Which of the Bradford Hill criteria for causality is best illustrated by the second finding, and why?

An epidemiologist is analyzing asthma case data for three states and find these results: State A: Population of 5 million, with an asthma rate of 8 per 1,000 people. State B: Population of 2 million, with an asthma rate of 12 per 1,000 people. State C: Population of 1 million, with an asthma rate of 10 per 1,000 people. What is the overall weighted average asthma rate (per 1,000 people) across all three states? (select one) What is the correct term to describe this rate?

A case-control study is conducted to investigate the association between long-term exposure to particulate air pollution (PM2.5) and acute myocardial infarction (AMI). Researchers recruit 100 individuals who have recently experienced an AMI (cases) and 200 individuals from the same community who have not had an AMI (controls). The exposure is defined as living in a high-PM2.5 area for at least 10 years, and data is obtained by asking participants about their prior home addresses. Data collection yields the following results: Among the 100 cases, 60 lived in a high-PM2.5 area. Among the 200 controls, 50 lived in a high-PM2.5 area. Based on the data above, what is the correct measure of association category? (select one) What is the measure of association you calculate? (select one)
