diseases found in less developed regions are no longer a problem in the United States
immunization programs in developing countries have been highly successful
** some migrants have inadequate immunization status with respect to vaccine-preventable diseases
3. Cyclic variations in the occurrence of pneumonia and influenza mortality may reflect:
seasonal variations in cases of influenza. ** (p. 218)
the fact that influenza is a disappearing disorder.
long-term changes in mortality trends.
both A and B

Influence of climate
-1-
Presence of environmental carcinogens
All of the above ** (p. 215)
5. Cyclic variations in the occurrence of disease may reflect:

8. A five-year prospective cohort study has just been completed. The study was designed to assess the
association between supplemental vitamin A exposure and mortality and morbidity for measles. The RR
for incidence of measles was 0.75 and the RR for measles mortality was 0.5. Which statement is correct?
A cohort study is not an appropriate study design in this case because the association between one
exposure and two different outcomes is being considered. **
One of the problems that this study may have faced is individuals lost to follow-up during the five-year
period.
A cohort study is not a good design to study this association because measles is a very common disease.
10. What factors should be considered in measuring long-term changes in disease frequency over time?
Changes in diagnostic criteria
Changes in the age distribution
Changes in the fatal course of the condition
All of the above** (p. 62)

the prevalence of the disease ** (p. 100)
the incidence of the disease
both the incidence and the prevalence of the disease
