These areas have been covered by means of answering given test questions.Question 1. a.The study is a prospective cohort study. The advantages of a prospective cohort study is that it can be used to calculate incidence of the disease and the risk of developing the outcome from the exposure. It is also suitable to study rare exposures. The study can also be used to study an exposure with multiple outcome (Wang & Clayton, 2006).b.Crude incidence rate is a of incidence that takes into account the time taken to observe the subjects. It incorporates time into the denominator. The denominator is usually in person-time units (Wang & Clayton, 2006)Crude incidence rate =numberofnewcasesofthedisease∈adefinedperiodoftimenumberofperson−timeunitatriskduringthedefinedperiodoftime =1879722419 = 0.0026 = 2.6 cases per 1000 person-year.
