QUESTION 2

  1. 1. The following table appeared in a recent report:

    Race-Adjusted Death Rates of colon Cancer in State Y, per 100,000

    Time Period

    Males

    Females

    1935 – 1938

    4.0

    2.7

    1940 – 1947

    5.2

    2.6

    1953 – 1958

    6.1

    2.3

    1961 – 1965

    0.7

    1.9


    The most likely cause for adjusting the rates by race in the table above is: 

    A.

    The populations being compared differ in age structure and the outcome rates vary by age.

    B.

    Rates of the disease vary by gender.

    C.

    The groups being compared demonstrate different trends.

    D.

    The populations being compared differ in age structure and race.

    E.

    The populations being compared differ by race and the outcome rates vary by race.

QUESTION 3
  1. A prerequisite for using direct age adjustment is that the age-specific death rates in the standard population must be available.

     True

     False

1 points   

QUESTION 4
  1. Age-adjusted mortality rates measure the actual risk of dying in a particular population.

     True

     False

1 points   

QUESTION 5
  1. Age adjusted mortality rates were generated for a cohort of 5,000 Chicago residents using the direct adjustment methods but two standard populations were used. Study A used Chicago as the standard population and study B used the United States as the standard population.  The age adjusted mortality rates calculated in the two studies will likely be the same.

     True

     False

1 points   

QUESTION 6
  1. Communities A and B have equal age-adjusted mortality rates. Community A has a lower crude mortality rate than B. One may conclude that:

    A.

    Both communities have identical age distributions

    B.

    Diagnosis is more accurate in A than B

    C.

    Community A has an older population than B

    D.

    Diagnosis is less accurate in B than A

    E.

    Community A and Community B have, on average, similar age.

    F.

    Community B has an older population than A.

  1. Direct and indirect standardization use somewhat different procedures to achieve the same basic objective.

     True

     False

QUESTION 8
  1. John has collected the number of deaths in 1938 by age and gender for Rockfish (population 6,000) and Walton's Mountain (population 7,000). He also knows the age and gender breakdown of each town. Before he compares mortality in the two populations, his best available strategy would be to:

    A.

    Compute a test for statistical significance

    B.

    Perform direct adjustment of rates

    C.

    Perform indirect adjustment of rates

    D.

    Calculate an attack rate

1 points   

QUESTION 9
  1. The major disadvantage of crude rates is that:

    A.

    They may not allow for comparison of populations that differ in size.

    B.

    They do not permit comparison of populations that vary in composition.

    C.

    They are difficult to calculate from available data sources.

    D.

    All of the above

QUESTION 10
  1. What would you be asking if you calculated an age adjusted SMR in an occupational study using the general population as your reference or standard population?

    A.

    Do people in the general population have a higher risk of mortality than do people of the same age in that certain industry?

    B.

    Do people working in a certain industry or occupation have a higher risk of mortality than would be expected in people of the same age in the general population?

    C.

    Do people who work have a higher risk of mortality than do people who do not work?

    D.

    It is not possible to calculate an SMR in an occupational study.
