Safe Sleep Video Intervention via Text Messaging to Low-Income Families: The SMARTER Randomized Clinical Trial

Listen to this summary

The study aimed to evaluate the effectiveness of a text-delivered video intervention promoting safe sleep practices among low-income families participating in the WIC program. Although the intervention did not significantly impact the primary outcomes related to safe sleep practices, it did show a higher rate of exclusive supine positioning at 60 days among participants who received the prenatal intervention compared to controls. Overall, the findings suggest limited effectiveness of the intervention in improving adherence to safe sleep practices.
