SIDS stands for what?

• A. Systemic Infant Death Syndrome
• B. Sudden Infant Death Syndrome
• C. Sudden Injury Death Syndrome
• D. Sudden Insomnia Disorder Syndrome

Answer: (B)

Acronyms in health terms often map directly to a precise medical concept. SIDS stands for Sudden Infant Death Syndrome. It refers to the sudden, unexplained death of an otherwise healthy infant, typically during sleep, when thorough investigation cannot determine a cause. The term is used because it describes a pattern rather than a single disease.

The other full forms don’t fit this established meaning: Systemic Infant Death Syndrome implies a body-wide condition not used in this context; Sudden Injury Death Syndrome would suggest a death caused by injury, which is not how SIDS is defined; Sudden Insomnia Disorder Syndrome relates to sleep problems in older individuals, not infant mortality.
