Week 6 Assignment
Asthma
Study
Asthma is a
chronic lung disease caused by inflammation of the lower airways and episodes
of airflow obstruction. Asthma episodes or attacks can vary from mild to
life-threatening. In 2007, about 7% percent of the U.S. population was
diagnosed with asthma and there have been a growing number of new cases since
that time. There are several known risk factors identified as triggers of
asthma symptoms and episodes, including inhalation of allergens or pollutants,
infection, cold air, vigorous exercise, and emotional upsets. There is also
growing evidence relating body-mass index to asthma in both children and
adults. Design a study to investigate whether there is such an association.
Choose a
study design and justify the reasons you chose the design over others.
Select a
statistical measure you would use to describe the association (if there is one)
between body mass index and asthma.
In
addition, address:
Subject
selection
Issues
relating to the measurement of both the exposure and the outcome
Potential
biases that the study might be prone to, and how they might be handled
Possible
confounding factors and effect modifiers and how to overcome their effect
Present the
information in a 750-1000-word report, using section headings where each
requirement is described and justified under each of the following headings:
Study Design, Statistical Measures, Subject Selection, and Measurement Issues.
Refer to
the “Key Elements of a Research Proposal.“
You are
required to use a minimum of three scholarly resources.
