Men between the ages of 46 and 90 years old were classified according to how many anger symptoms they exhibit and whether they have coronary heart disease or not. Among 588 men with the most anger symptoms, 53 had coronary heart disease. Among 195 men with no anger symptoms, 12 had coronary heart disease.
For those with the most anger symptoms, what is the percent increase in the risk of heart disease? (Round the answer to the nearest whole number.)? SHOW YOUR WORK.

Expert Solution
From the given data, the following Table is calculated:
| Coronary heart disease | No Coronary heart disease | Total | Cumulative Incidence | |
| Anger | 53 | 535 | 588 | 53/588=0.0901 |
| No anger | 12 | 183 | 195 | 12/195=0.0615 |
| Total | 65 | 718 | 783 |
Risk Ratio (RR) is given by:
The percent increase in the risk of heart disease = (RR - 1) X 100
= (1.4641 - 1) X 100
= 46%
So,
Answer is:
46%

According to most reports, as many as 46% of Americans will be
diagnosed with a psychological disorder during their lifetime. This
figure does not include people with symptoms of a disorder who do
not receive a diagnosis. Are psychological disorders being
over-diagnosed? Have the criteria for psychological disorders
become so broad that anyone can be seen as having a disorder?
