ABSTRACT Background Infant and young child feeding (IYCF) practices directly impact the health of <2-y-old children. Minimum dietary diversity (MDD) is an IYCF indicator to assess feeding practices of children aged 6–23 mo. The definition of MDD has recently been updated by the WHO and UNICEF, substituting “≥4 out of 7 food groups” (MDD-7FG) with “≥5 out of 8 food groups” (MDD-8FG). Objectives The goals of this study were to estimate the prevalence of IYCF indicators and identify the implications of the change in the prevalence of MDD at the national and regional levels of Bangladesh. Methods This study used data from the National Food Security and Nutrition Surveillance 2018–2019 round. A total of 1992 children aged 0–23 mo were included in this analysis. IYCF indicators and MDD were calculated according to the WHO-UNICEF guidelines. The difference between the prevalence of MDD-7FG and MDD-8FG is presented as percentage points. Results The prevalence of early initiation of breastfeeding was 43.8%, and exclusive breastfeeding was 56.2%. Approximately 55% of children maintained MDD (MDD-7FG), 48% received minimum meal frequency, and 28% received a minimum acceptable diet. Compared with MDD-7FG, the prevalence of MDD-8FG was lower among 6–23-mo-old children. The difference between MDD prevalence (MDD-8FG vs. MDD-7FG) was high for boys (44.0% vs. 53.2%), children aged 12–23 mo (53.4% vs. 63.4%), in urban areas (30.2% vs. 42.4%), in the Dhaka administrative division (42.0% vs. 56.3%), among uneducated mothers (37.1% vs. 47.1%), in households with ≤4 members (44.3% vs. 55%), and for middle-class households (40.3% vs. 57.6%). Conclusions The new method led to a decrease in the prevalence of MDD in Bangladesh. As the country prepares to implement the new indicator, it is critical to disseminate the new knowledge and its positive implication for improved child feeding and nutrition.
