This study focuses on the effects of breakfast omission on cognitive performance. We studied 279 children from low socioeconomic level background ranging in age from 8 years 7 months to 10 years 11 months, categorized nutritionally as: normal, wasted or stunted. Evaluation comprised three cognitive tasks designed to be applied with a microcomputer. Assessment took place in their natural setting, after a mean of 14h of overnight fasting, some having received a standard breakfast at random while the remaining children continued a fasting situation. We found no consistent association between study condition and performance in short-term visual memory, problem solving and attention tasks in any of the three nutritional groups. Stunted children showed significantly lower scores in the attention test irrespective of having received breakfast or not. These results suggest that given a motivating short-term task and maintaining routine conditions, missing breakfast does not affect the accuracy of the cognitive performance of children. Nutritionally affected children did not show a particular vulnerability to the fasting condition, but did show a specific cognitive deficit.
