Questions and Answers
  • 1. 
    • A. 

      Where people are living in low prevalence conditions, a specific disease or outcome is the basis for selection of the cases.

    • B. 

      The group is followed over a long period of time.

    • C. 

      Incidence rate in the exposed / Incidence rate in the unexposed

  • 2. 
    Relative Risk
    • A. 

      Incidence rate in the exposed / Incidence rate in the unexposed

    • B. 

      Where people are living in low prevalence conditions, a specific disease or outcome is the basis for selection of the cases.

    • C. 

      the group is followed over a long period of time.

  • 3. 
    Explain the cohort study  
    • A.

    • B. 

      Where people are living in low prevalence conditions, a specific disease or outcome is the basis for selection of the cases. Incidence rate in the exposed / Incidence rate in the unexposed

    • C. 

      The amount of people who are exposed to the disease and have the disease is divided by the number of people who were not exposed to the disease but caught the disease Where people are living in low prevalence conditions, a specific disease or outcome is the basis for selection of the cases.

  • 4. 
    Describe the advantages of the cohort study  
    • A. 

      Baby boom generation

    • B. 

      Very expensive and time consuming, complicated and difficult study. Subjects may be lost while trying to follow up during the course of the study. As well as the fact that exposures may be mis-classified.

    • C. 

      Allowance of the direct observation of risk. The exposure factor is well defined and can study exposures that are uncommon in the population. The temporal relationship between factor and outcome is known.

  • 5. 
    Describe the disadvantages of the cohort study  
    • A. 

      Allowance of the direct observation of risk. The exposure factor is well defined and can study exposures that are uncommon in the population. The temporal relationship between factor and outcome is known.

    • B. 

      Very expensive and time consuming, complicated and difficult study. Subjects may be lost while trying to follow up during the course of the study. As well as the fact that exposures may be mis-classified.

    • C. 

      Baby boom generation

  • 6. 
    • Identify an example of a cohort study
    • A. 

      Allowance of the direct observation of risk. The exposure factor is well defined and can study exposures that are uncommon in the population. The temporal relationship between factor and outcome is known.

    • B.

    • C. 

      Baby boom generation

  • 7. 
    Prospective cohort study
    • A. 

      Going forward in time and gathering up to date information about a person. Then watching watch what diseases develop in the future.

    • B. 

      Combination of retrospective and the prospective cohort study. This will be looking forward and backward in time to see what outcomes of diseases developed.

    • C. 

      A date is picked, such as at birth, exposures to disease are looked at all the way up to present day. Diseases that have developed in relation to exposures are examined.

  • 8. 
    Retrospective cohort study
    • A. 

      Going forward in time and gathering up to date information about a person. Then watching watch what diseases develop in the future.

    • B. 

      Combination of retrospective and the prospective cohort study. This will be looking forward and backward in time to see what outcomes of diseases developed.

    • C. 

      A date is picked, such as at birth, exposures to disease are looked at all the way up to present day. Diseases that have developed in relation to exposures are examined.

  • 9. 
    Historical Prospective cohort study
    • A. 

      A date is picked, such as at birth, exposures to disease are looked at all the way up to present day. Diseases that have developed in relation to exposures are examined.

    • B. 

      Combination of retrospective and the prospective cohort study. This will be looking forward and backward in time to see what outcomes of diseases developed.

  • 10. 
    Explain attributable risk  
    • A. 

      Provides an indication of the benefit to the population derived by modifying a risk factor. This measurement is the difference between the rate of disease in the non-exposed segment of the population and the overall rate in the population.

    • B. 

      Refers to the difference between the incidence rate of a disease in the exposed group and the incidence rate in the non-exposed group. Attributable risk is the difference between two incidence rates.

    • C. 

      Form of intervention studies.
