  1. Note: Maternal disenrollment was defined as having any gap in Medicaid coverage. Maternal health literacy was assessed using the S-TOFHLA and categorized as inadequate, marginal, or adequate per published technical guidance (Nurss JR, Parker R, Willams M, Baker D. TOFHLA: Test of Functional Health Literacy in Adults. Second ed. Snow Camp, NC: Peppercorn Books & Press; 2001). Maternal instrumental and relational social support was assessed using the Maternal Social Support Index and categorized low, medium, or high using tertiles per published technical guidance (Pascoe JM, Ialongo NS, Horn WF, Reinhart MA, Perradatto D. The reliability and validity of the maternal social support index. Fam. Med. Jul-Aug 1988;20(4):271–27)
