CHAPTER 11 TEST 1. A community has 60,000 inhabitants, 35,000 of which are female. Of the female population, 525 have been diagnosed with osteoporosis. What is the prevalence rate? 2. In the same community, the number of new cases of osteoporosis reported in the past year was 76 and the female population was 36,000. What is the incidence rate in this community, correct to the nearest whole number? 3. State population statistics for the year include: 2,555,000 Population of state 35,000 Female population (15-44) Maternal deaths 50 Live births 380,000 Infant deaths (<1 year) 4,293 neonatal deaths (<28 weeks) 2,527 fetal (>20 weeks) 3,011 Postneonatal deaths 1,766 Calculate the following: a. Maternal mortality rate b. Infant mortality rate c. Neonatal mortality rate d. Percent of all infant deaths that are neonatal deaths e. Perinatal mortality rate f. Postneonatal mortality rate g. Fetal death rate: (1) (2) 4. Without fetal deaths in the denominator Including fetal deaths in the denominator State Health Department data for the past year indicate: Population: Disease Diphtheria Hepatitis A Hepatitis B Mumps Rubella Rubeola 3,620,000 New Cases Deaths 22 7,882 1 4 3 2 0 3,444 33 78 56 0 Determine: a. Incidence of diphtheria per 1,000 b. Incidence of hepatitis 8 per 10,000 c. Case fatality ratio of hepatitis A d. Cause-specific death rate for mumps per 100,000 5. State cancer registry data for colorectal cancer indicate: Population Newly diagnosed cases Residents with "history of" Total M F 1,570,000 793 12,548 780,000 415 6,983 790,000 378 5,665 Calculate: a. Prevalence of colorectal cancer in males (per 100,000) b. Incidence of colorectal cancer in females (per 10,000) 6. During the past year, the State Health Department reported the following: State population: 5,610,000 Disease Pertussis Salmonellosis Shigellosis Newly Diagnosed Cases Deaths 168 9,820 550 1 4 1 1,410 9,995 6 0 0 STDs: Syphilis (all stages) Chlamydia Gonorrhea 7,000 Calculate: a. Incidence of chlamydia (per 1,000 population) b. Incidence of pertussis (per 1,000 population) c. Case fatality rate of syphilis d. Cause-specific death rate of salmonellosis (per 10,000 population) 7. A total of 500,000 males were reported to have a history of prostate cancer during the past year. Of these, 38% were white males and 62% were nonwhite males. The U.S. population was reported as 300 million, of which 145 million were males and 155 million were females. Among the male population, 110 million were white and 35 million were nonwhite. Calculate: a. b. c. Prostate cancer prevalence (per 100,000) Prostate cancer prevalence (per 100,000) white males Prostate cancer prevalence (per 100,000) nonwhite males 8. The multiplier used in vital statistics rates can also be designated as a power of 10 (10 to the nth power). The power is the number of Os following the number 1. The multiplier 100,000 is 10 to the 5th power; 10,000 is 10 to the 4th power, etc. Which power (is n) for the following? a. 100 b. 1 9. A community has a population of 76,000.
