Which of the following statements is NOT true when describing a proportionate mortality rate?

A) When calculating this measure, all deaths for the period of study are included in the denominator.

B) This measure is expressed as a percentage of all deaths.

C) This measure is used to describe the proportion of deaths in a defined population that is attributable to a specific cause.

D) This measure is used to describe the total number of deaths in a defined population, including all causes.

Tourette Syndrome is the involuntary twitching of motor or vocal muscles. It usually presents symptoms in adolescence and is much more common among boys than girls. You are researching Tourette syndrome for the CDC and find the following information. Your study population is 87,026

Number of People in Study Number of People Diagnosed:

Boys 46,410 191

Girls 40,616 154

Age 6-11 37,775 169

Age 12-17 49,251 176

What is the prevalence of Tourette Syndrome in your study?

A) 1.77/1000

B) 3.96/1000

C) 3.79/1000

D) 7.93/1000

Expert Solution

Answer:

1) Which of the following statements is NOT true when describing a proportionate mortality rate?

A) When calculating this measure, all deaths for the period of study are included in the denominator.
B) This measure is expressed as a percentage of all deaths.
C) This measure is used to describe the proportion of deaths in a defined population that is attributable to a specific cause.
D) This measure is used to describe the total number of deaths in a defined population, including all causes - Incorrect (Explanation: proportionate mortality rate relates the number of deaths from a particular condition to all deaths within the same population group for the same period).

2) Tourette Syndrome is the involuntary twitching of motor or vocal muscles. It usually presents symptoms in adolescence and is much more common among boys than girls. You are researching Tourette syndrome for the CDC and find the following information. Your study population is 87,026

Number of People in Study Number of People Diagnosed:

Boys 46,410 191

Girls 40,616 154

Age 6-11 37,775 169

Age 12-17 49,251 176

What is the prevalence of Tourette Syndrome in your study?

A) 1.77/1000
B) 3.96/1000 - Correct Option
C) 3.79/1000
D) 7.93/1000

Explanation:

Total number of People diagnosed with Tourette Syndrome = (191+154 = 345) OR (169 + 176 = 345)
Study Population = 87026
Prevalence rate = (No. of cases with the condition at a given time) / (Number in the population at risk)
To calculate per thousand = 1000*(345/87026) = 3.96/1000
