Evaluating Text Message Video Interventions for Improving Infant Sleep Safety PracticesText message videos for safe sleep show mixed results

This randomized clinical trial evaluated the efficacy of mobile health interventions aimed at reducing the risk of Sudden Unexpected Infant Death (SUID). The study targeted a high-risk demographic: pregnant mothers and infants enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) and Federally Qualified Health Centers. The primary objective was to determine if short educational videos delivered via text message could influence critical sleep behaviors during the prenatal and postnatal periods.

The study population consisted of 1,790 participants across 18 states. The intervention group received educational videos focused specifically on safe sleep practices, while the control group received similar video content focused on breastfeeding. This design allowed researchers to isolate the impact of sleep-specific messaging on maternal behavior. The intervention period began at 34 weeks of gestation and continued until 60 days postpartum, ensuring a consistent window of education.

Primary outcomes were measured at 60 days postpartum and included four key indicators: the use of the supine position, room sharing without bed-sharing, the absence of soft bedding, and the use of pacifiers. These metrics are standard clinical markers for reducing SUID risk. The study aimed to see if consistent, mobile-delivered content could bridge the gap in education for underserved populations who may have limited access to consistent prenatal counseling.

Analysis of the primary outcomes revealed no statistically significant differences between the intervention and control groups. Specifically, the rates of supine positioning ranged from 87.6% to 92.2%, while room sharing without bed-sharing ranged from 83.8% to 89.5%. Additionally, the avoidance of soft bedding and the use of pacifiers showed no significant variation between the groups. These results suggest that the specific content of the text messages (sleep vs. breastfeeding) did not significantly alter the primary safety metrics in this cohort.

However, a secondary outcome showed a statistically significant difference. Participants who received the prenatal-specific intervention demonstrated a higher rate of exclusive supine positioning at 60 days compared to the control group (70.6% vs. 60.9%). This 9.7% adjusted risk difference (95% CI, 3.8%-15.0%) suggests that while the broad primary outcomes were not significantly moved, specific prenatal interventions may have a targeted effect on certain behaviors. From a clinical perspective, the findings indicate that while mobile health platforms are accessible, the specific delivery method or content of these interventions may not be sufficient to significantly alter primary safety behaviors in the short term. Clinicians should note that while the intervention did not meet its primary endpoints, the slight improvement in exclusive supine positioning highlights the potential for targeted prenatal messaging. Further research may be needed to determine if longer engagement periods or different content delivery methods could yield more robust changes in infant safety practices.
