Key result
Heart rate variability and cardiac vagal tone, but not sleep state measures, were related to better developmental outcomes in very low birth weight preterm neonates.
Why the study?

Population
62 very low birth weight preterm neonates assessed at 33, 34, and 35 weeks conceptional age
Design

Do behavioral sleep states and cardiac vagal tone correlate with neonatal health and developmental outcomes in very low birth weight preterm neonates?
In very low birth weight preterm neonates, cardiac vagal tone and heart rate variability are better predictors of long-term developmental outcomes than behavioral sleep states.
Doussard-Roosevelt et al. (1996) conducted an observational in Very low birth weight preterm neonates (n=62). Behavioral sleep states (active vs quiet sleep) was evaluated on Neonatal health status and developmental outcomes. Heart rate variability and cardiac vagal tone, but not sleep state measures, were related to better developmental outcomes in very low birth weight preterm neonates.
