Question

•2- Use Table (6-4) Titled: Selected Statistics for a Hypothetical Population, July 1st to July 30th and calculate the following mortality rates:

v Crude Mortality Rate or Crude death rate

vInfant Mortality

vNeonatal Mortality Rate

vPerinatal Mortality Rate

vFetal Death Rate (Stillbirth)

vCase fatality rate (Ratio)

vDeath – to – Case Ratio

vMaternal Mortality Rate

vAge – specific mortality rate for persons aged 55 years or older.

vCause – specific mortality rate for those died from heart disease.

vCause – specific mortality rate for those died from stroke

vSMR for cancer among persons aged 55 or older.

TABLE 6-4 Selected Statistics for a Hypothetical Population, July 1 to June 30 160,000 40,000 44,000 3,300 Total 1-year population Population of women 15-49 years of age Population of 55 years of age and older Number of live births Number of fetal deaths Number of maternal deaths Total deaths Number of infant deaths 0-1 years of age Number of deaths under 28 days old Number of deaths between 28 days and 1 year Number of deaths of persons 55 years and older Number one cause of death in the county is heart disease-deaths from heart disease Number two cause of death in the county is from cancer-deaths from cancer Number three cause of death in the county is from cerebrovascular accident (stroke) Number four cause of death in the county is accidents Number of deaths from cancer age 55 years and older Number of persons diagnosed with heart disease Number of deaths from other causes Number of persons diagnosed with high blood pressure, arteriosclerosis, and atherosclerosis (precursors for a stroke) 504 1,200

Answer 1

1. Crude death rate = number of live birth /total midyear population × 100, 3300/160000×100=2.062
2. Infant mortality rate = no of death of the children under one year of age / total no of birth in the same year, 88/3300×1000=26.67%
3. Neonatal mortality rate = no of death from birth to 28 days old / total live birth ×1000, 4/3300×1000=1.21%
4. Perinatal mortality rate = late fatal and early neonatal death weighing 1000gm /total live birth ×1000, 66/3300×1000=20%
5. Foetal death rate = no of foetal death in a given period / total no of live birth +foetal death ×1000, 66/3300+66×1000=19.61%
6. Case fatality rate =no of death during a specific period of time after disease onset /no if person with specific diagnosis ×100, 133/5600×100=2.38%(CFR IN HEART DISEASE )
7. Death to case ratio =no of death during a specified period /new case of disease identify during the same period ×100
8. Maternal mortality rate = no of maternal death in a specified period /no of woman in reproductive age ×100, 5/40000×100000=12.5%
9. Age specific mortality rate for 55 years or older =no of death for 55yr/estimated population of the same group ×100000=848/44000×1000=19.27%
10. Case specific mortality rate (heart disease )=no of death from a specific case / midyear population ×100000, 133/160000×100000=83.13%, stroke 56/160000×100000=35%
11. SMR For cancer among person aged 55 or older
