The Behavioral Risk Factor Surveillance System (BRFSS) is cross-sectional panel survey used to collect quantitative data on adult behaviors and risk factors. It is one of the largest U.S. health data collection efforts. The data can be used to analyze associations on a state or country level.

For this assignment, use the "BRFSS Web-Enabled Analysis Tool" and the "Calculation Odds Ratio" worksheet. Refer to the "Odds Ratio Interpretation" document for assistance as needed.

You are required to cite to a minimum of two sources to complete this assignment. Sources must be published within the last 5 years and appropriate for the assignment criteria and public health content.

While APA style is not required for the body of this assignment, solid academic writing is expected, and documentation of sources should be presented using APA formatting guidelines.

This assignment uses a rubric. Please review the rubric prior to beginning the assignment to become familiar with the expectations for successful completion.

You are required to submit this assignment to LopesWrite.

Inconsistencies in language choice (register) or word choice are present. Sentence structure is correct but not varied. Documentation of sources is inconsistent or incorrect, as appropriate to assignment and style, with numerous formatting errors. 3. Satisfactory (79.00%) The table is complete but incorrect values are placed in the cells. Odds ratio is calculated and mostly correct but shows a slight misunderstanding. Odds ratio interpretation is presented, but slight misunderstanding is apparent. The association between the variables is summarized but shows a slight misunderstanding.

Points Earned Calculating Odds Ratio Odds ratio is a measure of association used in epidemiological studies to assess the relationship between disease and exposure. In this exercise, you will calculate and interpret odds ratio using real-world examples. Odds Ratio In case control studies the odds ratio (OR) is the measure of the association between the frequency of an exposure and the frequency of an outcome. The OR is an indirect measure of risk in case control studies because incidence rates cannot be calculated. The formula for odds ratio is: (A/C) ÷ (B/D) or (AD)/(BC). Remember, data from an output source may not be ordered according to the table. Ensure that the output data corresponds to the table, or you will calculate incorrectly when you apply the formula. Disease Status Exposure Status Yes No Total Yes A B A+B No C D C+D Total A+C B+D A+B+C+D For this assignment: 1. Retrieve the "BRFSS Web-Enabled Analysis Tool" resource provided in the study materials. o Select "Cross Tabulation." o Select "2015" for the year. o Select "Arizona" for the state. o Select "Alcohol Consumption: Binge drinkers (males having five or more drinks on one occasion, females having four or more drinks on one occasion)" for Step 2 Select Row. o Select "Chronic Health Conditions: Ever diagnosed with a depressive disorder, including depression, major depression, dysthymia, or minor depression" for Step 3 Select Column. o Skip Steps 4 and 5. o Select "Sample Size" for Step 6 Select Statistics and run the report for the cross tabulation. © 2020.

Refer to the formula provided above. Exposure Status Yes No Total Yes No Total 1. Present or describe the formula you used to arrive at your answer. Show all calculations. 2. Interpret the odds ratio. In your interpretation, describe the association between the variables and indicate whether there is a positive, negative, or no association. Part 2 Use the study material, "BRFSS Web-Enabled Analysis Tool," located on the CDC website, and run a report for two variables of interest to you. Exposure Status Yes No Total Yes No Total 1. Present or describe the formula you used to arrive at your answer. 2. Interpret the odds ratio. In your interpretation describe the association between the variables and indicate whether there is a positive, negative, or no association. 3. Discuss the public health importance of the association. 2 Odds Ratio Interpretation 1.0 or (≈ 1.0) > 1.0 < 1.0 Means that the odds of exposure among The exposure is cases is the same the not associated odds of exposure with the disease among controls Means that the odds of exposure among The exposure may be cases is greater than a risk factor the odds of exposure for the disease. among controls and positively associated with the outcome Means that the odds of exposure among The exposure may be cases is lower than the protective odds of exposure against the disease. among controls and negatively associated with the outcome © 2020.
