Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

No Breakfast

Fasting. Ad libitum water intake permitted.

Group Type NO_INTERVENTION

No interventions assigned to this group

Breakfast

Ad libitum intake of ready-to-eat-cereal with milk. Participants were given a choice of four commercially available RTECs with 1.8% fat cow's milk. Ad libitum water intake was also permitted. The four ready-to-eat-cereals were corn flakes, toasted rice, shredded whole wheat pieces with a sugar topping, and wheat, corn and oat shapes.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

The inclusion criteria were as follows: aged 11-13 years, willingness to consume RTEC with semi-skimmed cow's milk during the study, ability to follow verbal and written instructions in English, and normal vision with appropriate corrective lenses if required.

Exclusion Criteria

The exclusion criteria were as follows: inability to understand the objective of the cognitive tests or carry out the tests, behavioural difficulties or attention disorders, administration of any psychotropic medication in the month prior to testing or during testing, food allergies or intolerances which prevent consumption of RTEC and milk (e.g. coeliac, lactose intolerance), acute illness or feeling unwell within the week prior to testing or during testing, and hearing impairment that precluded the normal use of headphones.
