Note. Spearman’s correlations were used when WIC status, race, pregnancy complications, and adverse birth outcomes were included. WIC = Women, Infants, and Children (WIC); SES = socioeconomic status; PTQ = Negative Repetitive Thinking; MLQ-P = Presence of Meaning in Life; IL = interleukin. WIC status: 0 = not enrolled, 1 = enrolled; race: 0 = white, 1 = person of color; pregnancy complications: 0 = not present, 1 = present; adverse birth outcomes: 0 = not present, 1 = present; all other variables are coded as labeled in Table 1 or 2, in increasing order.
