“…We found that parental education was both positively and negatively associated with IYCF, depending on the different IYCF components. For example, comparing the reference category with others, parental education, in general, was found to be positively associated with complementary feeding status (5,20,50,53,58,61,67,71,(74)(75)(76)(77), whereas negatively associated with breastfeeding related indicators (6, 21,48,51,52,57,64,65,67,72,73). However, some studies also found positive association between parental education and breastfeeding related indicators (20,49,54,55,60,63,69,70).…”
