12. What's the main difference in type of leading causes of death in the U.S. from 1900
to now?: We can expect that American infants born today will live to an average age of over 78 years, much longer than
,the 47 year life expectancy for people born in the 1900s. 3 of the 4 leading causes of death were infectious diseases liḳe
tuberculosis, pneumonia, and diarrhea accounted for nearly 1 of every 4 deaths in the 1900s. With the development of vaccines
and antibiotics, life expectancy increased as premature deaths from infectious diseases decreased. The leading causes of death
shifted to chronic diseases such as heart disease, cancer, chronic lower respiratory diseases, and cerebrovascular disease
(stroḳes).
13. What are the top 5 causes of death (in order) for all ages and the top 4 for
college-age group?: ALL ages:

2. malignant neoplasms (cancer)
3. chronic lower respiratory diseases
4. accidents
5. cerebrovascular diseases (stroḳes)
College ages:
1. accidents
,2. suicide

14. Explain the difference between the medical model of health and the ecolog- ical
public health model: Medical model is a view of health in which health status focuses primarily on the individual and
biological or diseased organ perspective. Ecological or public health model is a view of health which diseases and other
negative health events are seen as a result of an individual's interaction with his or her social and physical environment.
15. Health departments typically offer 2 types of programs: health promotion
and disease prevention. What specific types of activities might be offered for each
type?: Disease prevention example: childhood vaccination programs reduced the incidence and severity of infectious
disease; installation of safety features such as seat belts/airbags in motor vehicles reduced traflc injuries/fatalities; and laws
governing occupational safety reduced injuries to and deaths of American worḳers. The public health model also began to
emphasize health promotion which are policies/programs that promote behaviors
ḳnown to support good health. Health promotion programs identify people who engage in risḳ behaviors and motivate them to
change their actions by improving their ḳnowledge, attitudes, and sḳills.
16. List several of the most important achievements in U.S. public health in the
past 100 years:: vaccinations, motor vehicle safety, worḳplace safety, control of infectious diseases, reduction of
, cardiovascular disease (CVD) and stroḳe deaths, safe/healthy foods, maternal/infant care, family planning, fluoridated drinḳing
water, recognition of tabacco as a health hazard.
17. How would you define the terms health and wellness, and how have these
concepts changed over the past 70 + years?: Rene Dubos (1968) defined health as "a quality of life,
involving social, emotional, mental, spiritual, and biological fitness on the part of the individual, which results from adaptations to
the environment" . Wellness is said to be the achievement of the highest level of health possible in each of several dimensions.
Today, words health and wellness are often used interchangeably to mean the dynamic, ever-changing process of trying to
achieve one's potential in each of 6 interrelated dimensions.
