aModel A included the dietary diversity and child-level characteristics. In Model B, the maternal level characteristics were also added with child-level factors, and in Model C, household and community-level characteristics were also included in addition to child and maternal-level factors. Moreover, multiple linear regression was conducted using those variables that were found to be significantly associated with infants’ and young children’s dietary diversity in the bivariate analysis
