Activity #1
Use this information and the information in the table below to answer the questions beneath the table:
In January of 1990, 1,010 young adults offered to participate in a 10-year prospective study to determine their risk of Type-I diabetes. This group underwent an initial blood test to determine whether they were diabetic, and eligible subjects were re-tested yearly for the next 10 years. Among the group that offered to join the study:
There were 2 individuals who were found to have diabetes on the initial blood screening; these 2 people were referred for treatment and were not enrolled in the study
There were 1,000 who were disease-free and remained disease-free for the entire 10 years of the study
7 individuals developed diabetes during the course of the study at the times indicated in the table below
1 individual who was initially disease-free were lost to follow-up during the study at the times indicated in the table below
? = Lost to follow-up + = Blood test positive for diabetes —— = Continued disease-free follow-up
Question 1: In the group that was eligible for study, what was the cumulative incidence of diabetes from 1990 to 1995?
Question 2: Using the table for the preceding question what was the incidence rate of diabetes from 1990 to 1994?
Activity #2
A sample of 100 middle-aged and elderly women was followed prospectively for 10 years in order to study rates of ovarian cancer. All subjects entered the study on January 1, 1990, and all were free of cancer at the beginning. All women were followed until December 31, 1999. None were lost to follow-up. During this period, six subjects were diagnosed with ovarian cancer, but they all survived to the end of the study.
Case #1 was diagnosed with ovarian cancer in January 1991.
Case #2 was diagnosed in January 1992.
Case #3 was diagnosed in January 1993.
Case #4 was diagnosed in January 1996.
Case #5 was diagnosed in January 1998.
Case #6 was diagnosed in January 1994
The time at which these 6 subjects developed cancer is shown in this table:
Use this information and the information in the table below to answer the questions beneath the table:
Question 1: What was the incidence rate of ovarian cancer from January 1, 1992 to December 31, 1996?
Question 2: what was the prevalence of ovarian cancer on December 31, 1995?
Activity #3
Consider a source population consisting of 1,000 adults. Assume that no subjects moved in or out of the population over the next 12 years, but there were some deaths. Among the 1,000 subjects, 990 remained alive and free of cancer from 2001 to 2012. Events in the other 10 subjects are depicted in the image below. Subjects 1, 2, 3, and 4 were known to have lung cancer in 2001. The beginning of a dashed line indicates a newly diagnosed lung cancer, and the dashed lines indicate the ongoing presence of lung cancer in living subjects (dashed lines), and deaths are indicated in the figure.
Question 1: What was the prevalence of lung cancer in 2003?
Question 2: What was the prevalence of lung cancer in 2008?
Question 3: What was the prevalence of lung cancer in 2011?
Question 4: What was the cumulative incidence of lung cancer from 2001 to 2012?
