Insights
Supine sleep positioning (SSP) is crucial for reducing SIDS risk. Adherence is suboptimal, especially for late preterm and minority infants, highlighting a need for improved family education on safe infant sleep practices.
Area of Science:
- Neonatal Health
- Public Health
- Pediatric Sleep Safety
Background:
- Sudden Infant Death Syndrome (SIDS) poses a significant risk, particularly to preterm infants.
- Supine sleep positioning (SSP) is a proven SIDS risk reduction strategy.
- Limited data exists on SSP prevalence among preterm infants in the U.S.
Purpose of the Study:
- To compare SSP prevalence in preterm versus term infants post-hospital discharge in the U.S.
- To identify racial/ethnic disparities in SSP adherence for both preterm and term infants.
Main Methods:
- Analysis of 2000-2011 Pregnancy Risk Assessment Monitoring System (PRAMS) data from 35 states.
- Categorization of infants by gestational age (GA) into preterm and term groups.
- Calculation of adjusted prevalence ratios (APR) to assess likelihood of SSP based on GA and race/ethnicity.
Main Results:
- SSP prevalence varied by GA, with term infants (66.8%) showing the highest adherence.
- Late preterm infants had a slightly lower likelihood of SSP compared to term infants (APR: 0.96).
- Significant racial/ethnic disparities in SSP were observed across all GA categories when comparing non-Hispanic Black (NHB) and Hispanic infants to non-Hispanic White (NHW) infants.
Conclusions:
- Overall adherence to SSP was suboptimal across all infant groups.
- Late preterm infants and NHB/Hispanic infants require targeted interventions due to lower SSP likelihood.
- Enhanced family engagement and education are critical to improve SSP adherence and reduce SIDS risk.
Objective:
Supine sleep positioning (SSP) has been shown to reduce the risk of sudden infant death syndrome (SIDS) and preterm infants are at higher risk for SIDS. Population-based estimates of SSP are lacking for the preterm population. The objectives of this study are: (1) compare the prevalence of SSP after hospital discharge for preterm and term infants in the United States; and (2) assess racial/ethnic disparities in SSP for preterm and term infants.
Study Design:
We analyzed the 2000 to 2011 data from the Pregnancy Risk Assessment Monitoring System of Centers for Disease Control and Prevention from 35 states. We measured prevalence of SSP by preterm and term gestational age (GA) categories. We calculated adjusted prevalence ratios (APR) to evaluate the likelihood of SSP for each GA category compared with term infants and the likelihood of SSP for non-Hispanic black (NHB) and Hispanic infants compared with non-Hispanic white (NHW) infants.
Results:
Prevalence of SSP varied by GA: ⩽27, 59.7%; 28 0/7 to 33 6/7, 63.7%; 34 0/7 to 36 6/7 (late preterm), 63.6%; and 37 0/7 to 42 6/7 (term) weeks, 66.8% (P<0.001). In the adjusted analyses, late preterm infants were slightly less likely to be placed in SSP compared with term infants (APR: 0.96, confidence interval: 0.95 to 0.98). There were racial/ethnic disparities in SSP for all GA categories when NHB and Hispanic infants were compared with NHW infants.
Conclusions:
All infants had suboptimal adherence to SSP indicating a continued need to better engage families about SSP. Parents of late preterm infants and families of NHB and Hispanic infants will also require greater attention given their decreased likelihood of SSP.
