Objective To examine the effects of nutrition, dietary practices, and other related factors on academic performance and IQ among children in Addis Ababa, Ethiopia. Methods A case-control study was conducted among 309 children aged 6–14 years attending public and private schools in low-income districts of Addis Ababa from March to August 2023. Binary and multinomial logistic regression models were used to estimate crude (COR) and adjusted odds ratios (AOR) with 95% confidence intervals. Results Hand washing (AOR = 3.7; 95% CI: 1.4, 9.8), access to toilets (AOR = 3.37; 95% CI: 1.25, 9.09), and effective teaching (AOR = 2.94; 95% CI: 1.04, 8.33) good academic performance. Stunting (AOR = 0.16; 95% CI: 0.04, 0.59), underweight (AOR = 0.25; 95% CI: 0.09, 0.70), and overweight (AOR = 0.04; 95% CI: 0.01, 0.14) were associated with poor academic performance. Low meal frequency (AOR = 2.65; 95% CI: 1.06, 6.67) and teachers with BA/BSc degrees (AOR = 6.97; 95% CI: 1.14, 42.68) predicted lower IQ. Conclusion Many factors, especially nutrition and diet, strongly influence academic and cognitive performance; targeted school interventions improve outcomes.
