Infant mortality rate is the number of deaths of children of the age ______ .
Appeared in: UP CHO - 10 September 2021
Explanation
- The Infant Mortality Rate (IMR) is a fundamental indicator of a population's health and socioeconomic status.
- It specifically measures the number of deaths of children under one year of age.
- The rate is standardized and expressed per 1,000 live births to allow for comparisons across different populations and time periods.
Why Other Options Were Wrong
- Option B: The denominator is incorrect. Standard public health metrics like IMR use a denominator of 1,000 live births for statistical stability and comparability, not 100.
- Option C: This option describes the Under-5 Mortality Rate (U5MR), not the Infant Mortality Rate. U5MR includes all deaths from birth up to five years of age.
- Option D: This option incorrectly combines the age group for the neonatal period (0-1 month or 0-28 days) with a denominator (per lakh, i.e., 100,000) that is used for the Maternal Mortality Ratio (MMR).

Clinical Relevance
- Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Definition of Infant Mortality Rate (IMR) as background academic context rather than a clinical decision trigger.
- Nurses and public health professionals use IMR as a primary indicator to assess the overall health of a community, reflecting the quality of prenatal and postnatal care, sanitation, nutrition, and socioeconomic conditions.
- A high IMR signals a need for targeted community health interventions, such as promoting institutional deliveries, improving immunization coverage, ensuring access to clean water, and providing nutritional support to mothers and infants.
- Understanding these key indicators is vital for policy-making, resource allocation, and evaluating the effectiveness of public health programs.
How to Approach the Question
- First, identify the key term in the question: 'Infant mortality rate'.
- Break down the definition of this rate into its two essential components: the specific age group and the denominator.
- Recall or deduce the definition of an 'infant' in a medical context, which is a child from birth to one year of age.
- Recall the standard convention for expressing mortality rates. Most, including IMR, are calculated 'per 1,000 live births' to create a standardized, comparable number.
- Systematically evaluate each option. Option A matches both the correct age group (0-1 year) and the correct denominator (per thousand).
- Eliminate other options by identifying their errors: Option B has the wrong denominator, Option C defines a different rate (U5MR), and Option D mixes up age groups and denominators from other rates (NMR and MMR).
Concept Tested & Keywords
- Concept Tested: Definition of Infant Mortality Rate (IMR)
- Stem keywords: Infant mortality rate, deaths of children, age
- Lead-in keywords: is the number of deaths
- Clinical cues: Age/sex group narrows the expected diagnosis, intervention, or normal reference range.
- Negative lead-in flag: false
