core functions of public health as declared by the Institute of Medicine. Which of
the following activities will be considered in meeting the essential public health
services of this core function?

E. All of the above
E. All of the above
The Institute of Medicine, in The Future of Public Health landmark release on the
mission and vision of public health, stated categorically that "assurance" is one
of the core functions of public health. As a public health professional assigned to
a local health department to direct a newly-created unit for public health service
assurance, which of the following should you expect to be included among your
areas of responsibility?

The lessons from the state of California's Tobacco Taxation Program are
indicative of the essential role of policy in disease prevention and health
promotion. In 1988, Californian Proposition 99 placed a 25 cent tax on cigarette
packaging ($90 million per year to change social norms/behavior). Ten years later
(1999), there had been a 27% reduction in smoking and a 19% decrease in lung
cancer death rates in the state. Therefore, governmental policies such as taxing
tobacco to reduce tobacco smoking among youths who are most sensitive to
price increases are essential for the improvement of population health. Policy
development as a core function of public health embraces all of the following
activities except:
A. Advocating for community needs and issues
B. Prioritizing health needs
C. Planning and developing policies
D. Evaluating programs
E. None of the above
D. Evaluating programs
,Public health achievement in the 21st century includes motor vehicle safety.
During 1925 there were 18 deaths per million vehicle miles traveled (VMT) and in
1997 there were 1.7 deaths per million VMT. The decrease in motor vehicle deaths
can be attributed primarily to the public health focus on:
A. Improvements in vehicle safety features
B. Public education on the importance of safety belts
C. Enforcement of traffic laws
D. Improved streets and highways
E. All of the above
E. All of the above
In 1990, more than 30% of all deaths occurred among children younger than 5
years old, primarily from infectious diseases. Today, that thought it staggering.
Public health initiatives such as immunizations, improved sanitation, clean water,
and improved food safety have virtually eliminated myriad infectious diseases,
including typhoid and cholera- two major causes of illness and death early in the
20th century. Which of the following conditions resulted in safe and healthier
food?
A. Refrigeration
B. Pasteurization
C. Healthier animal care, feeding, and processing
D. Improved food supply safety
E. All of the above
E. All of the above
Compared with the 1900s, average life span has increased in the United States as
the direct result of public health initiatives such as vaccinations, sanitation,
chlorination, motor vehicle and workplace safety, and improving people's
awareness of the importance of health lifestyle choices. Which of the following
are considered the broad health issues of public health today?
A. Preventing and controlling disease
B. Keeping our environment clean, healthy, and safe
C. Promoting good health practices
D. All of the above
E. None of the above
D. All of the above
Clinicians may examine men who are diabetic more often or more thoroughly
than men who are not. If this observation is accurate, and if an association is
observed between erectile dysfunction (ED) and diabetes mellitus in men, the
association may be due to which of the following bias?
a. Misclassification bias
b. Recall bias
c. Surveillance bias
,d. Interviewer bias
e. None of the above
C. Surveillance bias
If the relative risk in all subjects differs from the relative risk in the subjects
stratified by BMI, which of the following statements may explain this
observation?
A. BMI itself is a factor in type II DM
B. BMI is related to exercise
C. BMI is a confounder
D. All of the above
E. None of the above
D. All of the above
The incidence rate of chronic obstructive pulmonary disease (COPD) in those
who smoke is 400 per 10,000 person-years; in those who are exposed to air
pollution, it is 200; and in those with neither exposure, it is 40. Estimate the
incidence rate in those with both exposure, assuming an additive model.
A. 560 per 10,000 person-years
B. 640 per 10,000 person-years
C. 600 per 10,000 person-years
D. 240 per 10,000 person-years
E. 440 per 10,000 person-years
A. 560 per 10,000 person-years
Using the additive model:
(baseline rate) + (rate in those with smoke minus the baseline rate) + (rate in those
exposed to air pollution minus the baseline rate)
40+360+160 = 560 per 10,000 person-years
Assuming that smoke and air pollution exert independent effects on COPD in
question 10**, rendering this joint effect multiplicative, calculate the joint effects
of these two variables in the multiplicative model.
**"The incidence rate of chronic obstructive pulmonary disease (COPD) in those
who smoke is 400 per 10,000 person-years; in those who are exposed to air
pollution, it is 200; and in those with neither exposure, it is 40. Estimate the
incidence rate in those with both exposure, assuming an additive model. "
A. 1,000 per 10,000
B. 50 per 10,000
C. 2,000 per 10,000
D. 32,000 per 10,000
E. 16,000 per 10,000
, C. 2,000 per 10,000
Using the multiplicative model:
First, figure out the Relative Risk (RR) for smoking
(400/40) = 10
Then, the RR for air pollution
(200/40) = 5
Lastly, the joint RR
(10x5) = 50
Then we multiple the joint relative risk by the baseline rate to get the expected incidence
rate for the joint exposure:
40 x 50 = 2,000 per 10,000
In a case-control study relating smoking to cancer of the cervix in women, the
investigators found the crude odds ratio to be 6.6 and the Mantel-Haenzel odds
ratio, adjusted for age, to be 6.3. In addition, their stratified analysis by age
indicated the following odds ratio (OR) by the three age groups for smokers,
relative to nonsmokers: (a) age 20-29 years, OR = 27.9; (b) age 30-39 years, OR =
5.9; and (c) age 40+, OR = 2.8. Based on these results, age is considered to be a
(an):
A. Positive confounder
B. Negative confounder
C. Nuisance covariate
D. Effect measure modifier
E. Confounder
D. Effect Measure Modifier

A. Recall bias is minimized compared to case-control designs
B. It is relatively inexpensive compare to case-control design
C. Precise measurement of exposure possible
