Purpose: Increasing dietary diversity by ensuring household dietary availability is required, especially for children’s health. We investigated the impact of IMUT integration program in household’s dietary diversity conducted at two stunting locus of North Sumatera Province, Indonesia. Patients and methods: IMUT integration program was conducted in Huta Godang and Tolang, villages at Ulu Pungkut District, Mandailing Natal Regency in 2022. This quasi experimental study consisted of intervention and control group, each consisted of 4 dasawisma and a total of 80 toddlers were recruited through purposive sampling. Assessment of dietary diversity was conducted using an open questionnaire in SSGI 2021. Results: Substantial increase in diversified food intake was found following the implementation of IMUT program (p = 0.003). Prior to the implementation of IMUT, 28% of households participating in this study were not educated in providing diversified dietary intake, the proportion greatly reduced to just 9% after the program. Conclusion: IMUT integration program successfully increases household dietary diversity and serves as impactful educational platform for families. We suggest that this program may even be reproduced in other regions, especially those with similar stunting burden.
