1) Soda consumption is very common in the U.S. For the purposes of this question, assume that 30% of the population consumes the equivalent of 3 or more 12 oz. sodas per week (this is the prevalence of the exposure). A large multi-center cohort study was conducted to evaluate the association between soda consumption and risk of diabetes. At baseline, participants were asked about their typical soda consumption, and individuals who reported consuming 3 or more sodas per week were considered exposed. Participants were followed for 10 years, and the following results were obtained: Incident Cases of Diabetes 356 236 Person-Years Contributed 3+ sodas a week <3 sodas a week a) Name the appropriate measure of association corresponding to the excess rate of diabetes attributable to soda consumption among subjects who consume 3+ sodas per week. Calculate this measure (shown as a rate, using the correct units), and provide a brief interpretation of your answer 375234 399763 b) Calculate the excess proportion of diabetes attributable to soda consumption among those who consume 3+ sodas/week. Express your answer as a percent, and provide a brief interpretation c) Calculate the excess rate of diabetes attributable to soda consumption in the total population. Express your answer as a rate, and provide a brief interpretation of your answer d) Calculate the proportion of diabetes incidence that could be eliminated in the total population, if we could convince everyone to consume less than 3 sodas per week. Express your answer as a percent, and provide a brief interpretation
