Iron deficiency (ID) is a highly prevalent micronutrient deficiency, affecting individuals in both developing and developed countries. Previous research on children with ID report deficits attention related to variations brain dynamics as measured using electroencephelography (EEG). We here the results of analysis baseline data from randomized, double‐blind dietary intervention study involving 257 female students (ages 18‐26) at University Rwanda, Huye; 54 these participated behavioral EEG testing, 3 tasks designed assess attentional capture control: (a) simple reaction time (SRT), test perceptual processing speed; (b) Go/No‐Go (GNG), inhibitory control; (c) Attentional Network Task (ANT), three critical functions attention. were collected 64‐channel system (BrainProducts, Gilching, Germany), signals sampled 250 Hz. observed statistically significant relationships between blood measures iron status magnitude (positive) latency (negative) two components (P1/N1 P3); positive relationship one measure overall activity (global field power) specific engaged (power theta‐band activity).
