The study included 392,397 infants born in 36 states, which had response rates of 70 percent or more in 2000-2011. Researchers analyzed supine sleeping in the following gestational age categories: 27 weeks or less, 28-33 weeks, 34-36 weeks and 37-42 weeks.
Results showed both preterm and term infants had suboptimal rates of supine sleep positioning after hospital discharge. In addition, supine sleep positioning varied widely by state, with Alabama having the lowest rate at 50 percent and Wisconsin having the highest rate at 81 percent.
The most preterm group of infants (less than 28 weeks) had the lowest rate of supine sleep positioning at 60 percent. After adjusting for maternal age, education, race/Hispanic ethnicity, marital status, previous live birth, insurance status before pregnancy, method of delivery and maternal length of hospital stay, late preterm infants (34-36 weeks) were significantly less likely to sleep on their backs compared to term infants.
"Given the concerning data about inadequate adherence to safe sleep practices for all infants and in particular for preterm infants, we need to better engage families about adhering to safe sleep practices at the individual, community, hospital and public health levels," Dr. Hwang concluded.
