The Perinatal Mortality Rate (PMR) includes both late fetal deaths and early neonatal deaths. Which of the following correctly defines the denominator used in PMR?
- A Per 1,000 live births
- B Per 1,000 total births (live births + stillbirths) ✓
- C Per 1,000 mid-year population
- D Per 1,000 women of reproductive age
Correct answer: B. Per 1,000 total births (live births + stillbirths)
Explanation
Perinatal Mortality Rate is calculated as the number of stillbirths (fetal deaths ≥28 weeks) plus early neonatal deaths (first 7 days) per 1,000 total births (live births + stillbirths). Using total births as the denominator is essential because excluding stillbirths would underestimate perinatal deaths, particularly in settings with high stillbirth rates.
