- Brief Summary
This study is a school-based, randomised, controlled, parallel groups trial to examine the acute effect of breakfast (ready-to-eat-cereal and milk) vs. no breakfast on cognitive function and subjective state in 11-13 year old adolescents. It was hypothesised that the consumption of breakfast will have a positive acute effect on cognitive performance and subjective state compared with breakfast omission in 11-13 year olds.
- Detailed Description
This study is a school-based, randomised, controlled, parallel groups trial to examine the acute effect of breakfast (ready-to-eat-cereal and milk) vs. no breakfast on cognitive function and subjective state in 11-13 year old adolescents. It was hypothesised that the consumption of breakfast will have a positive acute effect on cognitive performance and subjective state compared with breakfast omission in 11-13 year olds. The study sample consisted of males and females aged 11-13 years who were recruited to take part in the study from a UK secondary school. There were two conditions in this parallel groups study: Breakfast and No breakfast (fasting). The breakfast intervention consisted of ad libitum intake of ready-to-eat-cereal with milk. Cognitive function was assessed at baseline and +70 and +215 minutes post-intervention. The Cambridge Neuro-psychological Test Automated Battery (CANTAB; Cambridge Cognition Ltd) was used to assess cognitive function. The battery included: Simple Reaction Time (SRT), 5-Choice Reaction Time (5-CRT), Rapid Visual Information Processing (RVIP), and Paired Associates Learning (PAL), which measured reaction time, visual-sustained attention, and visual-spatial memory respectively. Concomitant ratings of subjective mood, alertness, satiety, and motivation were taken throughout the morning using eight unipolar Visual Analogue Scales

Name Time Method Change from baseline Paired Associates Learning (PAL) performance baseline, 70 minutes post-intervention. Paired Associates Learning (PAL) task was administered on individual touchscreen portable computers.
- Secondary Outcome Measures
Name Time Method 5-Choice Reaction Time task performance baseline, 70 minutes and 215 minutes post-intervention Reaction time assessed by 5-Choice Reaction Time (5-CRT) task. The task was administered on individual touchscreen portable computers.
Subjective unipolar visual analogue scale ratings of motivation to try hard baseline, 15 minutes, 70 minutes, and 215 minutes post-intervention The unipolar Visual Analogue Scale is a horizontal line, 100mm in length, anchored by the extreme intensities of a single subjective feeling (e.g. 'not at all' to 'very'). The participant marks on the line at the point that they feel represents their perception of their current state. Participants responded to each Visual Analogue Scale using a touch screen computer by moving the cursor along a 100mm line with extreme anchors at each end. The initial location of the cursor was at the 50mm mark. There were 100 points on the scale, yielding possible scores of 0-100. Higher scores indicate a better outcome
Rapid Visual Information Processing task (RVIP) performance baseline, 70 minutes and 215 minutes post-intervention Visual sustained attention assessed by Rapid Visual Information Processing task (RVIP). The task was administered on individual touchscreen portable computers.
Subjective unipolar visual analogue scale ratings of energy baseline, 15 minutes, 70 minutes, and 215 minutes post-intervention The unipolar Visual Analogue Scale is a horizontal line, 100mm in length, anchored by the extreme intensities of a single subjective feeling (e.g. 'not at all' to 'very'). The participant marks on the line at the point that they feel represents their perception of their current state.
