ASTHMA RISK/ODDS RATIOS AND PREVALENCE/INCIDENCE RATES

In Week 4, you will continue to assume the role of the public health informatician and use your pre-intervention asthma surveillance data set from the CDC to calculate risk/odds ratios and prevalence/incidence rates. Review the data set from a population perspective and calculate various population ratios and rates for the asthma data in your Excel spreadsheet. You will then answer the following questions in a short application paper of 3–4-pages, explaining your results. You may refer to the suggested readings for this week.
Ratios and Rate Questions

[Note: School populations: Asthma elementary student count in this study is 800 for this school year. School’s population (A + B + C + D) = 7,200 students for this school year.]
• Does one school have a higher number of students with asthma?
• Which school has the highest number of students with wheezing?
• How many students had both asthma and wheezing?
• If you have asthma, what are the odds that you also have wheezing?
• Is the odds ratio for bronchitis and RAD lower or higher than asthma and wheezing?
• How many children with wheezing were prescribed medication? From those results, what is the risk ratio?
• Is the risk ratio for being prescribed medication for asthma higher or lower than being prescribed medication for wheezing?
• Are the risk ratios for asthma and wheezing higher for children under the age of 10 than they are for the survey population as a whole?
• What is the student asthma prevalence for the school district, i.e., A, B, C, D based on total student population as shown above?
• What is the student asthma incident rate for the school district, i.e., A, B, C, D based on total student population as shown above?
