Meanwhile, from the multivariate analysis, it was found that maternal education (p=0.216), maternal family income (p=0.462) and maternal attitude (p=0.998). Based on the results of the multivariate analysis, the mother's attitude factor is the factor that has the most influence on the malnutrition status of children under five because the value obtained is <0.998.
