Background : Stunting is the most common malnutrition condition found in children around the world. Many factors can affect toddler nutritional status and cause stunting in them. They include genetic factors, family socioeconomic level, medical history and feeding practices. The present study aims to determine the impact of those factors on stunting incidence in children aged 1-5 years.Subjects and Method: The data was analyzed using cross-sectional approach with 109 mothers with children aged 1-5 years. Data collection was carried out by the means of direct interview using a questionnaire that has been validated for contents and toddler and parent height measurement.Results: The results showed that father and mother height, dietary diversity and fish consumption influenced stunting incidence in children aged 1-5 years. The mothers’ height (p=0.045; OR=9.847) significantly influenced stunting incidence.Conclusion: These results showed that genetic factors including mother and father height, dietary diversity and fish consumption influence stunting incidence in children aged 1-5 years. Thus, there is a need for a strategy focusing on the assistance to mothers who have children with stunting with the aim of improving the quality of feeding practices, especially related to dietary diversity and fish consumption.Keywords: stunting, children, socioeconomicsCorrespondence: Prastiwi Novia Puspitasari.
