Plain English summary of protocol
Background and study aims
A lack of long-chain omega 3 fatty acids, vitamins and minerals in the diet has been linked to antisocial behavior; correcting such deficiencies may therefore improve children's behaviour. We aimed to test the effects on behaviour of omega 3, mineral and vitamin supplements in UK adolescents.
Who can participate?
All year 10 pupils (male and female, aged 14 - 16 years) in the Robert Clack School will be asked to volunteer for the study.
What does the study involve?
Participants are randomly allocated to take either capsules containing the recommended intake of vitamins, minerals and omega 3 fatty acids, or identical looking and tasting placebo capsules, for 3 months. Blood samples are taken before and after supplementation and any changes in behaviour are measured using teacher rating scales together with school disciplinary records.
What are the possible benefits and risks of participating?
Participants' behaviour may improve. There are minimal risks.
Where is the study run from?
University of Oxford (UK).
When is the study starting and how long is it expected to run for?
May 2010 to November 2011.
Who is funding the study?
Esmee Fairbairn Trust (UK)
