Short Answer
Complete Explanation
The term “perinatal” is formed from the prefix “peri‑” combined with the root “natal,” which relates to birth. In this context, “peri‑” denotes the period surrounding an event, indicating a time frame that includes moments before and after the central event—in this case, birth.
- Prefix “peri‑”:
Means “around,” “near,” or “surrounding” in Greek. - Root “natal”:
Derived from Latin “natalis,” meaning “pertaining to birth.” - Combined meaning:
“Perinatal” refers to the time span that starts shortly before birth (often defined as from the 20th week of gestation) and extends to shortly after birth (commonly up to 7 days or up to 1 month, depending on the definition used). - Medical usage:
Adopted in obstetrics and neonatology to describe health conditions, research, and care that involve both the mother and the newborn during this transitional period. - Etymological origin:
Greek “peri” (around) + Latin “natalis” (pertaining to birth) entered English medical vocabulary in the early 20th century.
Common Misconceptions
“Peri‑” means “after.”
The prefix denotes both before and after; it signifies a surrounding interval, not exclusively a post‑event period.
“Perinatal” only includes the day of birth.
Clinical definitions typically cover weeks before birth and days to weeks after birth, not merely the birth day itself.
FAQ
What is the exact time frame covered by the perinatal period?
Definitions vary, but the WHO defines it as beginning at 22 completed weeks of gestation and ending seven days after birth; some clinical contexts extend it to 28 days postpartum.
Is the prefix “peri‑” used only in medical terminology?
No, “peri‑” appears in many fields (e.g., pericycle in botany, periscope in optics) to denote a surrounding or adjacent relationship.
How does “perinatal” differ from “neonatal”?
“Perinatal” includes the maternal and fetal period around birth, while “neonatal” refers specifically to the newborn infant, typically the first 28 days of life.
