QUESTION 16

1. Imagine that exactly 5 years ago, a team of epidemiologists identified a study population of 4,500 men, 65-74 years, in Cedar Rapids, Iowa, to determine the incidence (or risk) of prostate cancer. Initial tests indicated that 515 of the men already had prostate cancer (and therefore not at risk). The remaining men were followed for 5 years to determine the cumulative incidence of prostate cancer. By the end of the follow-up, 156 men had developed prostate cancer. What was 5-year cumulative incidence?

   		37 new cases of prostate cancer per 1,000 men over the 5-year study
   		38 new cases of prostate cancer per 1,000 men over the 5-year study
   		39 new cases of prostate cancer per 1,000 men over the 5-year study
   		40 new cases of prostate cancer per 1,000 men over the 5-year study
   		41 new cases of prostate cancer per 1,000 men over the 5-year study

QUESTION 17

1. Imagine that a study of prostate cancer was initiated in Des Moines, Iowa. A total of 1,000 men, 55-64 years of age, with no prior evidence of prostate cancer were enrolled in a 4 year study. Each year during the study, the men being observed were examined and tested for presence of prostate cancer. The results of annual examinations revealed:
   20 cases confirmed at 1^st
   exam
   25 additional cases at 2^nd
   exam
   40 additional cases at 3^rd
   exam
   45 additional cases at 4^th
   (final) exam
   What is incidence density of prostate cancer in this group?

   		18 new cases of prostate cancer per 1,000 person-years in the study
   		34 new cases of prostate cancer per 1,000 person-years in the study
   		37 new cases of prostate cancer per 1,000 person-years in the study
   		42 new cases of prostate cancer per 1,000 person-years in the study
   		105 new cases of prostate cancer per 1,000 person-years in the study

QUESTION 18

1. On the first day of class, none of the 180 students had the flu. During the semester, 47 of the students got the flu. On the last day of class, only 34 students still had the flu. What was the point prevalence of the flu in the class on the last day of class?

   		75 cases of flu per 1,000 students on the last day of class
   		19 cases of flu per 1,000 students on the last day of class
   		189 cases of flu per 1,000 students on the last day of class
   		261 cases of flu per 1,000 students on the last day of class

QUESTION 19

1. In 2017, during the first week of January, 5,465 women, 60-74 years old, were screened for presence of osteoporosis at major women’s health fair held in Phoenix, AZ. A total of 374 cases of osteoporosis were identified at screening. What is period prevalence of osteoporosis in group?

   		28 cases of osteoporosis per 100 women 60-74 years old at the health fair during the first week of 2017
   		28 cases of osteoporosis per 1000 women 60-74 years old at the health fair during the first week of 2017
   		68 cases of osteoporosis per 100 women 60-74 years old at the health fair during the first week of 2017
   		68 cases of osteoporosis per 1000 women 60-74 years old at the health fair during the first week of 2017

QUESTION 20

1. If you calculate the indirect age-adjusted mortality for Small Town using age-specific mortality rates for Big Town, and we find an SMR of 150%, which of the following is true:

   		Mortality in Small Town is less than what we would expect in Big Town
   		Mortality in Small Town is more than what we would expect in Big Town
   		Mortality in Small Town is similar to what we would expect in Big Town
   		We do not know how mortality compares between Small Town and Big Town

Answer 1

Sol. 11

Age specific mortality rate is a mortality rate limited to a particular age group.

Cause specific death rate is the number of deaths from a specified cause per 100,000 person-years at risk.

Proportionate mortality describes the proportion of deaths in a specified population over a period of time attributable to different causes.

The standardized mortality ratio is the ratio of observed deaths in the study group to expected deaths in the general population.

So, the measure which shows how the the observed mortality in a population compares to expectations is "standardized mortality ratio".

Hence,last option is the correct answer for this question.
