Question
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.”
