Spearman correlation was used. Variables were coded as: Household food security (food insecure = 0/food secure = 1); Parity (primiparous = 0/multiparous = 1); Heartburn (yes = 0/no = 1); Health (poor or regular = 0/good, very good or excellent = 1); Hx of depression (yes = 0/no = 1); Latina subgroup (other Hispanic Latina = 0/Puerta Rican Latina = 1); Marital status (no partner = 0/partner = 1); Social support was a continuous variable.
