As an Epidemiologist You Are Asked Whether Eating Two Burgers From A
As an epidemiologist, you are asked whether eating two burgers from a fast food restaurant daily will lead to at least 20 lbs weight gain in one month. You decide to test the hypothesis by using a cohort study. Your sample consists of 100 people who ate 2 burgers daily for one month from a fast food restaurant. For comparison purposes, you have another set of 100 people who also ate from the same fast food restaurant for one month, but they ate healthy choices instead of burgers. Of course, you had sophisticated methods of keeping track and measuring their daily intake. Assuming all things being equal, at the end of the month, 32 of the people who ate burgers had gained 20 lbs or higher, while among those who had healthy choices, 12 were 20 lbs or higher. Requirements: Design a 2x2 table of a cohort study to assess the association between eating fast food burgers and 20 lbs weight gain. Show your calculations. Provide a 1-3 paragraph interpretation of the results. Design a 2x2 table of a case control study. How would you calculate and interpret the measure of association? Based on your results, what would you recommend? Your paper should: be 1 page in length. show how you calculated your answers. be free of spelling and grammar errors.
Paper For Above instruction
To assess the association between eating fast food burgers and gaining at least 20 pounds within one month, a 2x2 cohort table was constructed based on the provided data. The cohort study divides participants into exposed (burger eaters) and unexposed (healthy eaters), further categorized by whether they gained 20 pounds or not.
| Gained ≥20 lbs | Did Not Gain ≥20 lbs | Total | |
|---|---|---|---|
| Exposed (Burger Eaters) | 32 | 68 | 100 |
| Unexposed (Healthy Eaters) | 12 | 88 | 100 |
| Total | 44 | 156 | 200 |
The relative risk (RR) of gaining 20 pounds for burger eaters versus healthy eaters was calculated as follows:
RR = (Incidence in exposed) / (Incidence in unexposed) = (32/100) / (12/100) = 0.32 / 0.12 = 2.67
This indicates that individuals who ate two burgers daily had approximately 2.67 times the risk of gaining at least 20 pounds compared to those who ate healthier options. The data suggest a significant association between burger consumption and weight gain, emphasizing the potential impact of frequent fast-food intake on weight management.
For the case-control study, we reverse the analysis by setting cases as individuals who gained ≥20 lbs and controls as those who did not. The 2x2 table is constructed based on this case definition:
| Exposed (Burger Eaters) | Unexposed (Healthy Eaters) | |
|---|---|---|
| Cases (Gained ≥20 lbs) | 32 | 12 |
| Controls (Did Not Gain ≥20 lbs) | 68 | 88 |
The odds ratio (OR), which measures the strength of association in case-control studies, is calculated as:
OR = (a/c) / (b/d) = (32/68) / (12/88) = (0.4706) / (0.1364) ≈ 3.45
An odds ratio of approximately 3.45 indicates that burger eaters are over three times more likely to gain 20 pounds than those who eat healthy. This reinforces the findings from the cohort analysis, suggesting a strong association between fast-food burger consumption and significant weight gain.
Based on these results, I recommend reducing the frequency of burger consumption, especially among individuals at risk for unhealthy weight gain. Public health strategies should focus on promoting healthier dietary choices and limiting fast-food intake to prevent obesity-related health issues.
