Introduction: Energy intake is a source of energy used for metabolic processes, growth, temperature regulation, and physical activity. If energy intake is below average, children can suffer from stunting and malnutrition. Objective: This study aims to determine the dominant factors related to energy intake in children aged 25-30 months in Gambir and Sawah Besar Districts, Central Jakarta, in 2019. Method: This study used a quantitative approach with a cross-sectional design with a total sample of 98 children. Data collection was conducted using a questionnaire and 1x24 hour food recall. Data analysis used correlation tests, independent t-tests, and multiple linear regression tests. Result: The average child's energy intake is 1.065 kcal/day. Bivariate analysis using the T-test showed that there was an average difference between energy intake and eating frequency (p=0.007), minimum acceptable intake (p=0.008), and total milk consumption (p=0.0001). The results of the correlation test showed the difference between the average energy intake and carbohydrate intake (p=0.0005), protein intake (p=0.0005), and fat intake (p=0.0005). The results of multiple linear regression tests showed that the dominant factors influencing children's energy intake were carbohydrate intake (p=0.000), protein intake (p=0.000), and fat intake (p=0.000). Conclusion: This study concluded that carbohydrate, fat, and protein intake were the dominant factors influencing energy intake in children. © 2023, Muhammadiyah Palu University. All rights reserved.
