The number of deaths of children under 1 year of age per thousand divided by total number of live births in the population during a given year is called __________.

Appeared in: NHM UP Staff Nurse-2023 shift 1st

Explanation

The infant mortality rate (IMR) is the standard measure for the death of children under one year of age.
The formula is (Number of deaths of infants under 1 year in a year / Total number of live births in the same year) × 1,000.
This rate is a universally accepted indicator of the overall health status of a population and the quality of its healthcare system, particularly perinatal care.
The key components from the question stem—'deaths', 'children under 1 year', and 'per 1,000 live births'—directly correspond to the definition of the infant mortality rate.

Option A: This is incorrect because it measures deaths related to pregnancy and childbirth among women, not deaths of infants.
Option C: This is incorrect because 'morbidity' refers to illness, disease, or complications, not death. This rate measures sickness among pregnant or postpartum women.
Option D: This is incorrect because 'morbidity' refers to the incidence of disease or illness in a population, not death. This rate measures how many infants get sick.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Definitions of key public health mortality and morbidity indicators as background academic context rather than a clinical decision trigger.
Nurses and community health workers use the Infant Mortality Rate to identify health disparities, plan interventions, and advocate for resources in vulnerable communities.
A high IMR in a specific area might prompt public health nurses to focus on initiatives like promoting prenatal care, improving nutrition, and increasing vaccination rates.
Understanding these terms is essential for interpreting public health data, participating in health policy discussions, and educating patients and communities.

How to Approach the Question

First, break down the question stem into its key components: 'deaths', 'children under 1 year', and 'per thousand live births'.
Next, analyze the options by identifying the two main variables in each term: the population (infant vs. maternal) and the outcome (mortality vs. morbidity).
'Mortality' means death, while 'morbidity' means illness or disease.
Match the components from the question to the options. The question specifies 'deaths' (mortality) of 'children under 1 year' (infant).
This combination directly points to 'infant mortality rate'.
Eliminate the other options: 'maternal' options are wrong because the population is infants, and 'morbidity' options are wrong because the outcome is death.
