Race and ethnicity (coded as 0 for non-Hispanic white and 1 for all others), residing with an intimate partner (coded as 0 for no partner in home and 1 for partner in home), and WIC participation (coded as 0 for WIC nonparticipant and 1 for WIC participant) were dichotomized. Educational attainment (ranging from 1 for some high school to 7 for graduate degree) and food insecurity (ranging from 1 to 6) were measured continuously. Depressive and anxiety symptoms assessed at the prenatal and 2-month waves were averaged to create a composite of parental mental health symptomatology across the peripartum period.
