EXW 344 exam 1 with correct answersWhat is public health? - Answers -Public health is a field that encompasses many
disciplines in an effort to promote and protect health and prevent disease and disability
in defined populations and communities.
How did the discipline of public health begin and why? - Answers -Like medicine, public
health evolved for a variety of reasons. Responding to diseases of unknown origins
(counting decedents) and trying to prevent those diseases in populations are two main
influences on the development of public health.
Why are the prevention and control of chronic diseases important today in public
health? - Answers -Only 150 years in the past, infectious diseases were the leading
concern and the primary cause of sickness and death. Today, chronic or
noncommunicable diseases influenced by lifestyle and genetics are the greatest public
health concern. This remarkable transition in public health coincides with the beginning
of the physical activity story.
How has the area of public health become specialized? - Answers -An important part of
the evolution and history of public health has been the emergence of training programs
and techniques to address public health challenges. The establishments of the London
School of Tropical Medicine and Hygiene in the United Kingdom and the Johns Hopkins
School of Public Health in the United States in the early 20th century were key steps to
creating a workforce with the skills necessary for handling public health problems. Very
rapidly following these early efforts, additional training and certification of academic
programs took hold in the United States. In 2011, the United States and Mexico had 50
accredited schools of public health providing leadership and training opportunities for
master's and doctoral students. These training programs have evolved over the years,
resulting in widely accepted standards for areas of training and specialization in public
health.
What are the five pillars of public health? - Answers -Epidemiology and disease control,
environmental health, biostatistics, health administration, and health promotion and
health education.
What is epidemiology, and how does it advance public health? - Answers -Epidemiology
is the study of distributions and determinants of disease and disability in populations
and is the basic science of public health. Epidemiologists are most interested in a
defined population and how a disease or disability affects that population. What causes
the spread? How can it be prevented? How many people are affected? What types of
people or other organisms are possibly affected more than others? Who is at risk? How
many could be affected in the future? These are all questions that epidemiologists are
