Question Stem
Three liveborn babies die at different ages: Baby X at 5 days, Baby Y at 20 days and Baby Z at 8 months. Which classification is correct?
Options
A
All three are early neonatal deaths
B
Babies X and Y are early neonatal deaths
C
Babies X and Y are neonatal deaths, and all three are infant deaths
D
Only Baby X is an infant death
E
All three are neonatal deaths
Explanation
Neonatal mortality includes deaths within 28 days of live birth, so Babies X and Y are neonatal deaths. Early neonatal mortality is restricted to the first 7 days, so only Baby X is early neonatal. Infant mortality includes deaths during the first year of life, so all three are infant deaths.
Option Validity
A) only Baby X died within the first 7 days.
B) Baby Y died after the early neonatal period.
D) all three deaths occurred during the first year of life.
E) Baby Z died after the first 28 days and is therefore not a neonatal death.
