A hypothetical cohort study of pesticide exposure and cancer followed exposed pesticide workers and a comparison group of non-exposed employees of the same company over a 30-year period. Researchers found that the incidence of cancer among exposed workers was 55.3 per 1,000. In the comparison cohort not exposed to pesticides, the incidence of cancer was 15.7 per 1000. Calculate the relative and attributable risks of exposure to pesticides and development of cancer.
Epidemiology Question 7 When an individual has the disease then they were definitely exposed to the Factor A but if exposed to Factor A this disease sometimes develops. Factor A is: A necessary, but not sufficient, cause A sufficient, but not necessary, cause A necessary and sufficient cause Neither necessary not sufficient Question 8 When an individual is exposed to Factor A this disease always develops and if there is an absence of Factor A the disease will not develop....

The data of a major referral hospital showed that most patients with ischemic heart disease (IHD) were black American. Based on this, it was concluded that black Americans are at higher risk of IHD compared to other community groups. How would you describe the conclusion? A. Correct, because risk factors for IHD are more common in black African American. B. Incorrect, because no test of statistical significance has been made C. Incorrect, because prevalence is used instead of incidence D....
