Answer Key

In addition to examining incidence, Disease Detectives may use data on mortality (death) from melanoma. The table below presents this type of data for 1969-1998.

Figure 2. Age-adjusted melanoma mortality rates by race and gender, 1969–1998.
(Source: National Center for Health Statistics, CDC)

Graph shows rate per 1000,000 from 1973 through 1998. Rate is steadily increasing for white/males and white/females.  Rate is constant for black/males and black/females.

6. Define “mortality rate.”




7. Referring to Figure 2, give the 1998 mortality rates for the following groups:


 White Men ______________ 
White Women ______________ 
Black Men ______________ 
Black Women ______________ 


8. Note the difference in mortality rates between white men and white women. Give two possible reasons for this difference. 




Part III
(Recommended time: 5 minutes)

Your interpretation of Figures 1 and 2 underscores the magnitude of the problem among white men in the U.S. You decide to examine the data further and come upon a map from the National Cancer Institute of U.S. melanoma mortality rates for white men from 1970-1994.

Figure 3. 

Cancer mortality rates by state economc area (Age adjusted 1970 population) Melanoma of skin: White males, 1970-94.  Shows higher rate in south and west, lower rate in north.

9. Using the map (Figure 3), list two geographic areas with high melanoma death rates.




10. Referring to Figure 3, give two possible reasons for higher mortality in the places that you listed in the Question 9. 




Part IV
(Recommended time: 5 minutes)

The governor wants to know how Delaware’s melanoma mortality rate compares with that of other states. While preparing for the meeting, you come upon a figure ranking melanoma mortality for white men aged 20–49, by state, during 1970-1994.

Figure 4. Melanoma mortality for white men aged 20-49, by state — United States, 1970-1994.

The ranking of melanoma mortatliy for white males inthe age group 20-49

11. Using Figure 4, give the five states that have the highest mortality rates for white men?




12. List two reasons why melanoma mortality rates might be higher for white men in Delaware than for men in neighboring states and some states in the south.
