Micronutrients Intake and Mathematics Achievement among Primary School Children in Magelang, Central Java

Romiza Arika, Sapja Anantanyu, Yulia Lanti Retno Dewi


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 obser­vational analytic study with a cross sectional design. The study was conducted in four elemen­tary schools in Pakis, Magelang, Central Java, from March to April 2019. A sample of 177 stu­dents was selected by simple random sam­pling. The dependent variable was math achieve­ment. The independent variables were iodine, iron, and zinc intakes. The data were collected by question­naire and analyzed by a multiple linear regres­s­ion.

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 children
