Question
Assignment 2 Measures of Mortality Smithville is a community of 100,000 persons (45,000 females, 55,000 males) During 1985, there were 1,000 deaths from all causes. All cases of tuberculosis have been found, and they total 300: 200 males and 100 females. Fifty of the cases have been diagnosed in the past year. During 1985, there were 60 deaths from tuberculosis, 50 of them in males. Use the above data for questions1 through 5. For questions 1 and 5 use a base of 10,000 1. Crude mortality rate in Smithville is: 2. The proportionate mortality due to tuberculosis is 3. The case fatality rate for tuberculosis in 1985 is 4. The cause-specific mortality rate for tuberculosis is 5. The sex-specific mortality rate for tuberculosis in males is 6. Arkansas recorded 200 cases of Tuberculosis with 77 deaths in 1997. What would be the case fatality rate for Tuberculosis in Arkansas? What would you estimate that this rate would compare with the case fatality rates of Heart Disease or Cancer? How would the rate compare with the case fatality rate for AIDS? What does this rate say about Tuberculosis? Page 1 of 1 193 words P Type here to searchExplanation / Answer
1. The crude mortality is a measure that is obtained to calculate the number of people that have the risk of dying in a certain amount of time (in this case 1985) out of 10,000 people (as it is specified in the problem). So it is calculated like this:
M= Number of deaths in 1985 / total amount of population * 10,000
M= 1000/100,000 * 1000 = 100
Out of 10,000 people in 1985, 100 died.
2. We take the data for a certain period of time as in the last question, We use the number of deaths caused by tuberculosis and the number of total deaths. This time, as it does not say we should use a 10,000 base, we will use 100 base as it is normally used. So:
M = 60/1000 * 100 = 6 Deaths out of 100 are for tuberculosis
3. the case fatality rate is how many people die from a disease out of how many are diagnosed. It is not clear the period of time when the 300 cases of tuberculosis in this problem was diagnosed, but let´s suppose it was in 1985. The soultion would be:
F= number of deaths caused by tuberculosis / number of cases diagnosed * 100
F= 60/300 * 100 = 20%
In this case is times 100 because it is a percentage (%).
4.
Number of deaths caused by tuberculosis / total population * 1000
60/100,000 * 1000 = 0.6
