Question
I need help answering this discussion post. The topic is Identifying study design and making
Transcribed Image Text:The study involved enrolling 4,000 women in 1990 and following them for 10 years to determine the relationship between alcohol consumption and liver cirrhosis. At the start, no participants had liver cirrhosis. Among those who drank alcohol daily (n=2,200), 200 developed liver cirrhosis. For those who did not drink (n=1,800), 75 developed liver cirrhosis. No participants died or were lost to follow-up.
Tasks:
1. **Research Question:**
- Is there an association between **drinking alcohol daily** and **liver cirrhosis**?
2. **Randomized Control Trial:**
- Discuss whether this could be conducted as a randomized control trial and why.
3. **Study Design:**
- Identify and specify the type of study design, explaining the reasoning.
4. **2x2 Table Completion:**
| | Liver cirrhosis | No Liver cirrhosis |
|----------------------|-----------------|--------------------|
| Drank alcohol daily | 200 | 2,000 |
| Did not drink | 75 | 1,725 |
| **Total** | 275 | 3,725 |
5. **Relative Risk Calculation:**
- Calculate the relative risk showing formulas and work.
6. **Findings:**
- Summarize the association in a sentence.
7. **Public Health Implications:**
- Discuss the implications of this study.
8. **Reflection:**
- Reflect on the activity and understanding of epidemiology.
This exercise helps in understanding the relationship between lifestyle factors and health outcomes using an epidemiological approach.
