The article “Americans are ‘Getting the Wrong Idea’on Alcohol and Health” (Associated Press, April 19, 2005)reported that observational studies in recent years thathave concluded that moderate drinking is associated with a reduction in the risk of heart disease may be mis-leading. The article refers to a study conducted by theCenters for Disease Control and Prevention that showedthat moderate drinkers, as a group, tended to be better educated, wealthier, and more active than nondrinkers. Explain why the existence of these potentially con-founding factors prevent drawing the conclusion that moderate drinking is the cause of reduced risk of heartdisease.
