What is the standard denominator used for maternal mortality ratio?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. 100,000 live births

Maternal mortality ratio expresses maternal deaths related to pregnancy or its management per 100,000 live births, providing a standardized indicator for comparing maternal health outcomes across populations.

Option by option

  • A. 1,000 total population

    Total population is not the standard denominator for this ratio.

  • B. 1,000 women of reproductive age only

    Women of reproductive age are used in other measures, not the standard MMR denominator.

  • C. 100,000 live births (correct)

    Correct: maternal mortality ratio is reported per 100,000 live births.

  • D. 100 pregnancies at any stage

    Pregnancy count alone is not the conventional reporting denominator.
