Postnatal Mortality Rate is defined as deaths from 28 days through the rest of the first year of life per 1000 live births. Which option matches this definition?

• A. Death within first 28 days
• B. Death from birth to 28 days
• C. Death from 1 year onwards
• D. Death from 28 days through rest of first year

Answer: (D)

Postnatal Mortality Rate measures deaths that occur after the neonatal period, specifically from 28 days of age through the end of the first year, per 1000 live births. This window excludes the first 28 days (neonatal period) and also excludes deaths that occur after the first year, focusing on what happens in the second to twelfth month of life. The option describing deaths from 28 days through the rest of the first year matches this definition exactly. The other options refer to different time frames: within the first 28 days is neonatal mortality, birth to 28 days covers the neonatal period as well, and death from 1 year onwards lies outside the first year.
