The CIID has the same principles as other nonverbal IQ tests, correlates well with the WISC and has excellent psychometric qualities. Aim: to investigate the relationship between sociodemography and nutritional status with cognitive level of elementary school children in Padang Timur District using CIID. Methods: Analytical research with a cross sectional study design from February to May 2022 on elementary school children in Padang Timur, Padang city. Results: There is a relationship between the cognitive level of elementary school children with nutritional status, mother's education, family income and father's education. Conclusion: The most important factor in influencing a child's cognitive level is nutritional status. Keywords: cognitive, sociodemographic, nutritional status INTRODUCTION Cognition is the ability to process information through the senses. 1 Cognitive related to the level of intelligence. Cognitive is more passive and refers to the ability to understand something, while intelligence is more active and refers to behavior that shows that potential. IQ test (Intelligence Quotients) is used to measure a person's level of intelligence. In 2013 as many as 88 children (6.9%) of 1,284 children aged 6 to 12 years in Indonesia reported having a low IQ. 2 The correlation between socioeconomic level, nutritional status, and cognitive function has been regularly demonstrated in studies from both industrialized and developing nations. Good nutrition is useful in supporting the development of the brain and nervous system. 3 Malnutrition in children is known to have long-term side effects on cognitive function, school completion and productivity during adulthood. 4,5 Standard measurement for assessing cognitive levels in children is the Wechsler intelligence scale for children (WISC). 6 However, WISC has limitations in that experienced psychologists must assess it. This can be a problem in developing countries, such as Indonesia, because the number of child psychologists is limited and they are not evenly distributed throughout the country. Moreover, WISC takes about
