As An Epidemiologist, Are You Asked Whether Eating Two Burge
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 1-2 pages in length. Show how you calculated your answers. Be free of spelling and grammar errors.

Introduction
Assessing the relationship between dietary choices and significant weight gain is critical in epidemiology to inform public health recommendations and individual behavioral modifications. A cohort study provides a prospective approach to determine if eating two burgers daily is associated with gaining at least 20 pounds within a month, while a case-control study offers a retrospective method to evaluate the odds of burger consumption among those who gained substantial weight. This paper constructs 2x2 contingency tables for both study designs, performs relevant calculations, and interprets their implications in the context of obesity prevention.
Cohort Study Design and Calculations
The cohort study involves 200 participants split into two groups: 100 individuals who consume two burgers daily (exposed group) and 100 individuals who opt for healthy foods (unexposed group). The primary outcome is weight gain of 20 lbs or more. Data from the study show that 32 individuals in the exposed group and 12 in the unexposed group experienced this level of weight gain.
Constructing the 2x2 table:
| Gained ≥20 lbs | Did not gain ≥20 lbs | Total | |
|---|---|---|---|
| Exposed (Burger eaters) | 32 | 68 | 100 |
| Unexposed (Healthy eaters) | 12 | 88 | 100 |
Calculations:
Risk in exposed group: Rexposed = 32/100 = 0.32
Risk in unexposed group: Runexposed = 12/100 = 0.12
Relative Risk (RR):
RR = Rexposed / Runexposed = 0.32 / 0.12 ≈ 2.67
This indicates that individuals who eat two burgers daily are approximately 2.67 times more likely to gain at least 20 lbs in a month compared to those who choose healthy foods.
Interpretation:
The cohort study reveals a significant association between eating fast food burgers and substantial weight gain, with a relative risk of roughly 2.67. This suggests the dietary habit of consuming two burgers daily increases the likelihood of weight gain ≥20 lbs by more than twofold. Public health interventions should emphasize moderation in fast-food consumption and promoting healthier dietary choices to mitigate rapid weight gain and related health issues.
Case-Control Study Design and Calculations
In a case-control design, the focus shifts to individuals who gained ≥20 lbs (cases) and those who did not (controls). Assume we select 100 cases (those who gained ≥20 lbs) and 100 controls (those who did not). Using the data:
- Among cases: 32 reported regularly eating two burgers
- Among controls: 12 reported regularly eating two burgers
The 2x2 table is constructed as follows:
| Exposed (Burger eaters) | Not exposed (Non-burger eaters) | Total | |
|---|---|---|---|
| Cases (≥20 lbs gain) | 32 | 68 | |
| Controls (no ≥20 lbs gain) | 12 | 88 |
Calculations:
Odds of exposure among cases: Ocases = 32/68 ≈ 0.471
Odds of exposure among controls: Ocontrols = 12/88 ≈ 0.136
Odds Ratio (OR):
OR = Ocases / Ocontrols ≈ 0.471 / 0.136 ≈ 3.46
This suggests that the odds of regularly consuming two burgers are about 3.46 times higher among those who gained ≥20 lbs compared to those who did not.
Interpretation of Measures of Association
The odds ratio indicates a strong association between burger consumption and significant weight gain. An OR greater than 1 signifies that frequent burger eating is associated with higher odds of substantial weight gain. Although the case-control study is retrospective, it supports findings from the cohort study and emphasizes the potential impact of fast-food diets on weight management. Public health policies should therefore aim at reducing fast-food intake, especially in populations at risk of obesity.
Recommendations
Based on the findings, reducing the daily consumption of fast-food burgers can substantially decrease the risk of rapid weight gain and subsequent health complications such as metabolic syndrome. Healthcare providers should advocate for healthier dietary interventions and awareness campaigns to discourage excessive fast-food intake. Further research might explore other lifestyle factors influencing weight gain and evaluate long-term effects of dietary changes.
