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 - Correct Answer- 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 - Correct Answer- 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 - Correct Answer- E. All of the above
Compared with the 1900s, average life span has increased in the United States as the direct

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. 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 - Correct Answer- 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 - Correct Answer- 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.
