Your educational estimate will appear here.
Relative risk compares your answers to the typical U.S. baseline. If it shows 1.00×, your estimate is similar to average. 2× would mean about twice the baseline risk; 0.5× is half.
Absolute risk is the size of the risk in real-world terms. That’s 0.42 per 1,000 births — about 1 in 2,381. Even when a relative risk looks big, the absolute number may still be small.
- Population estimate, not a diagnosis. This educational model summarizes published associations; it can’t predict an individual outcome.
- What changes the number? Sleep position/surface, bed/couch sharing, soft bedding/head covering, smoke exposure, overheating, breastfeeding, pacifier use, prematurity/low birth weight, and age (highest around 2–4 months).
- How to act on it: See Evidence-Based Ways to Reduce Risk for clear, practical steps.
