#7- Now assume that you conducted a case-control study to answer the research

question regarding the association between job stress and hypertension. Using

the same data provided in the table above, calculate the odds ratio for

hypertension for those with high stress compared to those with little/ no job

stress. Round to two decimal points for odds ratio (more precise).

8. Interpret the odds ratio you calculated in #7.

10. For the case-control study scenario, how would you define your cases (disease

status). Make sure to include the population.

Answer 1

No 7.

The odds ratio for hypertension for those with high stress compared to those with little/ no job stress is.

(Hypertension with a high level of job stress/Nonhypertensive with a high level of job stress) / (Hypertensive with no job stress/Nonhypertensive with no job stress)

$\large (385\div 15,425)\div (233\div12,703)$

$\large 0.0249\div 0.0183=1.36$

The odds ratio is 1.36.

No 8.

The odds are 1.36 greater than someone with a high level of job stress will also have hypertension.

No 9.

In the case-control study, you have to follow the case(Hypertensive patient) from a source like a hospital or in a specific community. Then find the research question, here it is job stress related to hypertension.

Then identify the control population.
