Soda consumption is very common in the U.S. For the purposes ofthis question, assume that 25% of the population consumes theequivalent of 3 or more 12 oz. sodas per week (this is theprevalence of the exposure). A large multi-center cohort study wasconducted to evaluate the association between soda consumption andrisk of diabetes. At baseline, participants were asked about theirtypical soda consumption, and individuals who reported consuming 3or more sodas per week were considered exposed. Participants werefollowed for 10 years, and the following results were obtained:

1. Was this a prospective study or a retrospective study, was it ageneral cohort or a specific exposure cohort, and was thecomparison group internal or external?
2. Name and calculate the appropriate measure of disease(morbidity) frequency for each group.

3+ sodas/wk:  

<3 sodas/wk:  

3. Calculate the appropriate relative measure ofassociation for the relationship between soda consumption anddiabetes risk. Name the measure of association, and provide a briefinterpretation of your answer.
4. Calculate the excess rate of diabetes attributable to sodaconsumption among subjects who consume 3+ sodas per week. Use thecorrect units, and provide a brief interpretation of youranswer.
5. Calculate the excess rate of diabetes attributable to sodaconsumption in the total population, Use the correct units, andprovide a brief interpretation of your answer.
6. Calculate the proportion of diabetes incidence that could beeliminated among subjects who consume 3+ sodas/week, if we couldconvince everyone to consume less than 3 sodas/week. Express youranswer as a percent, and provide a brief interpretation.
7. Calculate the proportion of diabetes incidence that could beeliminated in the total population, if we could convince everyoneto consume less than 3 sodas per week. Express your answer as apercent, and provide a brief interpretation.
