Variables in the Obesity and Coronary Heart Disease Study

Discuss the variables of the study devoted to finding the association between obesity with coronary heart disease.

In a hypothetical study to examine the association between obesity with coronary heart disease (CHD), 9,400 patients were selected to participate. Participants were classified as obese or not and followed over five years to assess if they were diagnosed with coronary heart disease. Discuss what the exposure variable is. What is the disease? Calculate the relative risk. Can you think of any confounding variables? What are they?
