The incidence of malnutrition can increase the risk of morbidity and mortality of children. The purpose of this study was to determine the factors associated with the nutritional status of children under-five years. The research method used is quantitative with cross sectional design. In this study, using the method of Proportionate Stratified Random Sampling, the quantity of respondents was 107. The instrument used were a questionnaire and weight scales. The analysis data involved using chi-square test and multiple logistic regression. There was a significant association between environmental sanitation (p-value = 0.01, OR=4,95), history of exclusive breastfeeding (p-value = 0.001, OR=5,84), and a history of infectious disease (p-value = 0.03, OR= 3,51). There is a need for screening children under five with nutritional problems and improving health on community nutrition.
