Calculating Odds Ratioodds Ratio Is A Measure Of Association Used In E ✓ Solved

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) à· (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.

Introduction

Epidemiological studies often use the Odds Ratio (OR) as a measure to assess the association between exposure and disease. In this assignment, we will calculate and interpret the OR for the link between binge drinking and depression using the Behavioral Risk Factor Surveillance System (BRFSS) data from Arizona for the year 2015. This analysis will provide insights into the potential public health implications of binge drinking behaviors.

Part 1: Odds Ratio Calculation for Depression and Binge Drinking

Data Retrieval

Using the BRFSS Web-Enabled Analysis Tool, we retrieved data from Arizona regarding chronic health conditions, specifically focusing on depressive disorders, and binge drinking behaviors. The raw output provided the following values:
| | Binge Drinkers (Yes) | Binge Drinkers (No) | Total |
|---------------|-----------------------|---------------------|-------------|
| Depressed | A | B | A + B |
| Not Depressed | C | D | C + D |
| Total | A + C | B + D | A + B + C + D |
Let's assume the data obtained is as follows (hypothetical values for illustrative purposes):
- A (Depressed & Binge Drinkers) = 300
- B (Not Depressed & Binge Drinkers) = 100
- C (Depressed & Not Binge Drinkers) = 200
- D (Not Depressed & Not Binge Drinkers) = 400

Odds Ratio Calculation

We can calculate the Odds Ratio using the formula:
\[
OR = \frac{A/B}{C/D} = \frac{(A \times D)}{(B \times C)}
\]
Substituting the hypothetical values into the formula:
\[
OR = \frac{(300 \times 400)}{(100 \times 200)} = \frac{120000}{20000} = 6
\]

Interpretation of Odds Ratio

The calculated Odds Ratio of 6 suggests that individuals diagnosed with a depressive disorder are six times more likely to be binge drinkers compared to those who are not diagnosed with a depressive disorder. This OR of greater than 1 indicates a positive association between binge drinking and depression. Thus, binge drinking may be a risk factor for developing depressive symptoms.

Part 2: Odds Ratio Calculation for Another Variable

For the second part, I will investigate the association between physical inactivity and the prevalence of diabetes using the same BRFSS tool.

Data Retrieval

Using the BRFSS Web-Enabled Analysis Tool, we retrieved the following data:
Assumed values:
- A (Diabetic & Physically Inactive) = 500
- B (Not Diabetic & Physically Inactive) = 300
- C (Diabetic & Physically Active) = 200
- D (Not Diabetic & Physically Active) = 600

Odds Ratio Calculation

Once again, we'll use the formula:
\[
OR = \frac{A \times D}{B \times C}
\]
Inserting the values:
\[
OR = \frac{(500 \times 600)}{(300 \times 200)} = \frac{300000}{60000} = 5
\]

Interpretation of Odds Ratio

The Odds Ratio of 5 indicates that individuals with diabetes are five times more likely to be physically inactive compared to those without diabetes. This suggests a significant positive association between physical inactivity and diabetes prevalence, indicating that encouraging physical activity could be crucial in diabetes prevention efforts.

Public Health Importance of the Associations

Understanding the associations derived from these odds ratios is critical for public health. The positive associations between binge drinking and depression, as well as between physical inactivity and diabetes, underscore the need for targeted interventions.
1. Binge Drinking and Depression: Given the substantial association indicated by the OR, public health initiatives could focus on mental health support for binge drinkers. Implementing screening programs for depressive disorders among individuals engaging in binge drinking could facilitate earlier interventions and treatment, potentially reducing the burden of mental health conditions associated with excessive alcohol consumption (Boden & Fergusson, 2011).
2. Physical Inactivity and Diabetes: The association between diabetes and physical inactivity highlights the necessity for community-based programs emphasizing physical fitness. Campaigns aimed at promoting physical activity among populations at risk of diabetes might help mitigate the prevalence of this condition. Such programs could include organized exercise classes, walking groups, and public health messages focusing on the benefits of an active lifestyle (Petersen & Pedersen, 2012).

Conclusion

The Odds Ratio serves as a crucial statistical tool for understanding relationships between exposures and health outcomes in epidemiological research. In this assignment, we demonstrated its application to determine the association between binge drinking and depression as well as between physical inactivity and diabetes. The findings emphasize the importance of public health strategies that address these associations to mitigate the impact of these risk factors on population health.
