Which denominator and multiplier does the maternal mortality rate use?
AMid-interval population, expressed per 100,000
BLive births in the period, expressed per 1,000
CLive births in the period, expressed per 100,000
DMid-interval population, expressed per 1,000
Answer & Solution
Correct answer: C. Live births in the period, expressed per 100,000
1. The numerator counts deaths from causes related to or aggravated by pregnancy, up to 42 days after a pregnancy ends.
2. The denominator is the number of live births reported in the same period, which is why the measure is really a ratio.
3. The result is conventionally expressed per 100,000 live births.
4. Per 1,000 live births is the convention for infant, neonatal and postneonatal rates, not maternal deaths.
5. A mid-interval population denominator would make this an ordinary cause-specific mortality rate instead.
