Relationship between breakfast omission and cognitive performance was investigated in primary school children using a cross-over, within-subject design. Subjects from SRK st. Joseph Penampang (n=51; m=25; f=26; age 10y) were recruited. Prepreparation was an overnight fast but non-compliance was 39.6%. However results from non compliers to the overnight fasting protocol were not significantly different from compliers irrespective of treatment groups. On assessment day, subjects were randomly assigned to receive breakfast (BR) or no breakfast (NBR) in school. One week later, treatment groups were reversed. Breakfast treatment was a kaya sandwich, a 200ml chocolate malt drink and a common variety banana (approximately 413 kcal). One hour after treatment, subjects completed four cognitive tasks for: (1) short-term memory (Serial Recall Task, SRT and BrownPeterson Task, BPT), (2) spatial memory (Spatial Memory Task, SMT), and (3) attention (Visual Search Task, VST). Brown-Peterson Task was not further analysed due to incorrect data. BR subjects performed better than NBR subjects in SRT, especially as serial positions progressed (p<0.05). NBR subjects significantly made more errors than BR subjects (p<0.05). BR subjects performed worse than NBR subjects in SMT and VST, albeit insignificant differences (p>0.05). Findings from the VST were congruent with Dickie & Bender (1982) and Chandler et al., (1995). Findings differed from Mahoney et al. (2005) in SMT. Poorer BR subjects (household income <RM1000/mo) performed significantly better for spatial (p<0.05). Thin NBR girls were severely affected in SRT (p<0.05). These findings could be due to (1) the level of food deprivation between compliers and non-compliers; (2) the breakfast treatment (i.e. glycaemic composition); and (3) nutritional status of the subjects. In conclusion, breakfast omission significantly affected short term memory, (p<0.05) but not for attention and spatial memory (p>0.05).
