Measuring Health of Population Flashcards
what is the incidence rate?
‘the rate of occurrence of new cases arising in a given period in a specified population’
What is the prevalence?
“the frequency of existing cases in a specified population”
In a eye exam of 2,477 people in 2016, a total of 310 had cataracts. What statistic can be calculated from this data?
A= cumulative ratio
B= Incidence rate
C= Population at risk
D= Prevalence rate
E= Relative risk
D= Prevalence Rate
What is the Crude mortality rate?
Crude Mortality Rate: for all deaths from all causes during a certain period
what is the ‘standardized mortality rate?”
The age-standardization of rates eliminates the influence of different age distributions on the morbidity or mortality rates being compared.
There is great variation between countries in the reported crude mortality rates for heart disease.
Finland has a crude heart disease death rate approximately three times that of Brazil, but the standardized rate is the same.
Similarly, the United States of America has a crude rate more than twice that of Brazil, yet again, age standardized rates are similar.
The Crude Mortality Rate (CRM) in a developed country is 33 per 1000. The CMR in a smaller, developing country is 12 per 1000. Which one of the following best explains the data?
A. The health care system of the developing country is more effective than that in the developed country
B.Infant mortality in the first week is higher in developing countries, but it is not included in the crude death rate
C.Crude mortality rates can be higher for developed countries due to a higher proportion of older people
D.Mortality rates in the developing country are lower due to high emigration rates
C.Crude mortality rates can be higher for developed countries due to a higher proportion of older people
how do you calculate the infant mortality rate?
how do you calculate the maternal mortality rate?
= the number of maternal deaths per 100,000 live births
Which of the following measures is an indicator of the quality of maternal healthcare services?
A.Fertility rate
B.Neonatal mortality rate
C.Under five mortality rate
D.Population at risk
neonatal mortality rate
