y Bookmarks Window Help a bb-tc.touro.edu Age Sex It was possible to determine prevalence of CHD from the initial Framingham examinations. The numerator of the prevalence rates includes both new and pre-existing cases of disease a population. The table below presents the prevalence of CHD at the initial examination in the Framingham study. Remember that any persons with CHD at this first examination were excluded from further study. Calculate the prevalence rates per 1000 for the blank spaces Number examined Number with GHD Prevalence Rate/1000 1,083 941 2,024 45-62 Total Females 30-44 45-62 1,317 1.128 2,445 5.3 21 18.8 It was possible to determine incidence of CHD by following all persons with CHD at the initial examination and determining how many of them had CHD on subsequent examinations. The next table shows numbers of persons found to have CHD by the 8-year examination (assume that the "population at risk" column takes into account persons followed for 8 years). Calculate the incidence rates per 1000 for the blank spaces below at risk New CHD 20 Incidence per/1000 24.2 Males 30-39 40-49770 50-59 617 81 30-39 40-49 50-59 1,036 955 792 Females 0.97 What is the prevalence rate per 1000 population in A- 66.7 males 30-44(A)? 4.6 What is the prevalence rate per 1000 population in c.n ok Save and Submit to save and submit.

Explanation / Answer

1. Prevalence rate per 1000 population in males 30-44 = (5/1083) x 1000 = 4.61 (Option B is correct)

2. Prevalence rate per 1000 population in males 45-62 = (43/941) x 1000 = 45.70 (Option I is correct)

3. Total prevalence rate per 1000 population in males = (48/2024) x 1000 = 23.72 (Option D is correct)

4. Total prevalence rate per 1000 population in females = (28/2445) x 1000 = 11.45 (Option G is correct)

5. Incidence rate per 1000 population in males 40-49 = (51/770) x 1000 = 66.23 (Option F is correct)

6. Incidence rate per 1000 population in males 50-59 = (81/617) x 1000 = 131.28 (Option H is correct)

7. Incidence rate per 1000 population for females 40-49 = (19/955) x 1000 = 19.89 (Option C is correct)

8. Incidence rate per 1000 population for females 50-59 = (52/792) x 1000 = 65.65 (Option A is correct)

* The 6th and 8th questions ask for Incidence rate for ages 50-49. I considered them to be typos and answered for thee ages 50-59.
