4. A research group wanted to know if daily consumption of energy drinks was a risk factor for hypertension in college-aged adults. The enrolled two groups of students as either 'drinkers' or 'non-drinkers' and measured their blood pressure monthly to determine if hypertension developed within one year. The results are as Drinkers Non-drinkers Developed hypertension 65 106 Did not develop hypertension 435 1394 a. Is this a cohort or case control design and how do you know? (1 point) b. Calculate either relative risk or an odds ratio to test the link between exposure and disease. Which metric is more appropriate and why? (3 points) c. How much risk of hypertension (if any) can you attribute to consumption of energy drinks? (3 points)Explanation / Answer
Ans a) A case control study is an observation done between two groups where the outcomes are different and comparison is made on some casual factors. It is not a case control or cohort design because the cohort design is usually done to compare factors between two groups of individuals suffering from a particular disease. Here, we are trying to find out the applicability of hypertension in drinkers and non-drinkers.
Ans b) The total number of drinkers who were taken in the test are 500 and total number of non-drinkers are 1500.
In the drinkers it is noticed that 13% suffered from hypertension out of the total and nearly 7% of non-drinkers of total faced hypertension. We cannot say if the results are appropriate or in sync because there are other factors that may cause hypertension.
Ans c) There is risk of hypertension when one consumes energy drinks because the sugar content is high. However, the results show that even non-drinkers can get hypertension and there are many factors associated with the same. In case of drinkers also it was observed that only 13% were at risk of hypertension and rest did not. So, consuming energy drink not necessarily put you to risk.
