 The study aimed to estimate the prevalence of minimum dietary diversity, MDD, and consumption of ultra-processed foods in children 6 to 23 months of age according to sociodemographic variables, finding that the overall prevalence of MDD was 63.4 percent, with lower prevalences among children who lived in the North Region, whose mothers or caregivers had zero to seven years of education and lived under moderate or severe food insecurity. Ultra-processed foods were consumed by 80.5 percent of the children, with the highest prevalence in the North Region. The most frequently consumed food groups from the MDD indicator were grains, roots and tubers, dairy products, sweet or salty cookies slash crackers, and instant flowers. The study highlights the need to strengthen policies and programs to ensure adequate and healthy infant nutrition.
