Question 1: The number of maternal deaths per 100,000 live births is called-
- A. Maternal mortality rate
- B. Maternal mortality ratio (Correct Answer)
- C. Infant mortality rate
- D. Perinatal mortality rate
Explanation: ***Maternal mortality ratio***
- This is the standard epidemiological indicator defining the number of **maternal deaths per 100,000 live births**.
- It measures the risk of death due to pregnancy in a population.
*Maternal mortality rate*
- This term is often used interchangeably with maternal mortality ratio, but technically, a **rate usually includes time in the denominator** (e.g., deaths per person-year).
- While related to maternal mortality, it's not the precise term for deaths per live births.
*Infant mortality rate*
- This measures the number of **deaths of infants under one year of age per 1,000 live births**.
- It does not specifically refer to deaths of mothers.
*Perinatal mortality rate*
- This calculates the number of **stillbirths and deaths in the first week of life per 1,000 total births** (live births plus stillbirths).
- It focuses on deaths around the time of birth in the infant, not the mother.
