Insights
Few mothers follow all infant sleep recommendations. Understanding common sleep patterns and their variation by demographics can help improve infant safety and reduce sudden unexpected infant death (SUID).
Area of Science:
- Public Health
- Pediatrics
- Sleep Medicine
Background:
- The American Academy of Pediatrics (AAP) provides evidence-based guidelines for infant sleep to prevent sudden unexpected infant death (SUID).
- Understanding how these recommendations are implemented in real-world settings is crucial for effective public health strategies.
- Common infant sleep and care practices can vary significantly based on demographic factors.
Purpose of the Study:
- To identify and define common patterns of infant sleep and care practices in Illinois.
- To assess the prevalence of these patterns across various maternal demographic characteristics.
- To inform targeted interventions for improving infant sleep safety.
Main Methods:
- Maternal self-reported data on AAP-recommended practices were collected from the 2016-2020 Illinois Pregnancy Risk Assessment Monitoring System.
- Practices included breastfeeding duration, maternal smoking status, and four key sleep environment factors (back sleeping, safe surface, clear sleep area, no bed-sharing).
- Nonhierarchical cluster analysis identified six distinct patterns of infant sleep and care practices, with prevalence analyzed across demographic variables using chi-squared tests.
Main Results:
- Only 19.3% of mothers reported adherence to all six recommended practices; this varied significantly by demographics.
- Identified patterns included: 8.1% adhering to all four sleep environment recommendations, 28.1% bed-sharing with breastfeeding, 11.7% bed-sharing without breastfeeding, 25.1% no bed-sharing with back sleeping, and 7.8% no bed-sharing with non-back sleeping.
- Individual practice prevalence ranged from 49.6% (no items in sleep area) to 90.8% (no maternal smoking).
Conclusions:
- Common patterns of infant sleep and care practices are diverse and do not consistently align with all AAP recommendations.
- Significant demographic variations in these patterns highlight the need for tailored approaches to promote safe infant sleep.
- Analyzing these patterns offers valuable insights for developing and refining interventions to reduce SUID.
Objective:
The American Academy of Pediatrics (AAP) publishes evidence-based infant sleep recommendations to prevent sudden unexpected infant death (SUID). We defined common patterns of infant sleep and care practices in Illinois and assessed variation in patterns across demographic characteristics.
Methods:
We measured maternal report of AAP recommended practices in the 2016-2020 Illinois Pregnancy Risk Assessment Monitoring System, including breastfeeding greater than or equal to 8 weeks; no maternal smoking; and 4 aspects of the sleep environment for infant sleeping on back, on an approved surface, without items in sleep area, and without bed sharing. We applied nonhierarchical cluster analysis, coupled with knowledge of AAP recommendations, to define 6 mutually exclusive patterns of infant sleep and care practices. We produced weighted prevalence estimates for each individual practice and pattern and examined differences by maternal race and ethnicity, age, parity, education, and socioeconomic status using χ2 tests.
Results:
Prevalence estimates for individual practices ranged from 49.6% for infants sleeping without items in sleep area to 90.8% for not smoking. When examining patterns, only 19.3% of new mothers reported all 6 recommended practices; this pattern varied significantly across all demographics examined. The prevalence of the other 5 patterns were as follows: 8.1% following all 4 sleep environment practices, 28.1% bed sharing and breastfeeding, 11.7% bed sharing and no breastfeeding, 25.1% no bed sharing and back sleep positioning, and 7.8% no bed sharing and no back sleep positioning.
Conclusion:
Examining common patterns of infant sleep and care practices provides improved understanding of how infant sleep recommendations are followed and may inform intervention strategies.
