6. Red meat consumption is common in the United States. For the purposes of this question, assume that 28% of the population consumes the equivalent of three or more 12 oz. of red meat per week. A study conducted to evaluate the association between red meat consumption and risk of hypertension. At baseline, participants were asked about their typical red meat consumption, and individuals who reported consuming three or more 12 oz of red meat per week were considered exposed. Participants were followed up for six years, and the following data was obtained. 22 points Meat Consumed >12 oz a week <12 oz a week Total Hypertension 372 187 Person-Years Contributed 35,424 18.197 a. Name the study design of the excerpt provided above. 2 points b. Name two advantages, and two disadvantages of the study design above. 4 points c. Name and calculate the appropriate measure of disease frequency for each group. 4 points >12 oz a week: <12 oz a week:

Answer 1

red meat consumption is common in u.s.

a). The name of the study designed above is a cohort study. The term cohort is defined as a group of people who share a common characteristic of experience within a defined time period. Two advantages of cohort study are - • Multiple outcomes can be studied together. • There is no Recall bias. Jww.disadvantages of cohoot study are - • It is a time consuming study. • The person or expert carrying out the study loss to follow up c). Incidence rate at Disease frequency is calculated by the 2 12 02 a week Disease frequency - No of new case Total Population at risk. x 1000 = 372 X1000 C 3474 35424 372X100 35796 - 10-5 per 1000 per years rate of Disease frequency is 21202 a week - calculated by the Incidence 187_ X.1000 14+ 18197 = 10.3 per 1000 per year.
