<![CDATA[Background: Micronutrient deficiency in school children is estimated at more than 2 million children. Deficiency of micronutrients causes damage to the physical functioning of children, impaired cognitive function, learning processes that are less than optimal, and poor academic performance. This study aimed to analyze the relationships between iodine, iron, zinc intake, and math achievement primary school children.Subjects and Method: This was an obserÂvational analytic study with a cross sectional design. The study was conducted in four elemenÂtary schools in Pakis, Magelang, Central Java, from March to April 2019. A sample of 177 stuÂdents was selected by simple random samÂpling. The dependent variable was math achieveÂment. The independent variables were iodine, iron, and zinc intakes. The data were collected by questionÂnaire and analyzed by a multiple linear regresÂsÂion.Results: Iodine intake (b= 0.02; 95% CI= 0.01 to 0.03; p= 0.001) and zinc intake (b= 0.23; 95% CI= 0.04 to 0.41; p= 0.017), and iron intake (b= 0.08; 95% CI= -0.01 to 0.17; p= 0.052) increased math achievement in primary school children.Conclusion: Iodine intake, zinc intake, and iron intake increase math achievement in primary school children.Keywords: iodine, zinc, and iron, math achievement, primary school childrenCorrespondence: Romiza Arika.
