Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Omega-3 supplementation of 1.59g (combined docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA)) per day for 12 weeks administered in an encapsulated omega-3 powder.
The main marker for adherence to the intervention is the change in omega-3 blood levels. A calendar sheet will be used for parents to track their child's consumption of the powder, and this will be returned at the end of the study.
Dietary intake of omega-3 at baseline will be captured using the Polyunsaturated Fatty Acid Food Frequency Questionnaire.

Electroencephalographic (EEG) recording and subsequent quantification of EEG power in the delta, theta, alpha, and beta frequency bands from each task (eyes-open resting, eyes-closed resting and executive function tasks) will allow a measure of task related activation by comparing eyes-open EEG with EEG during the "Mr Ant" and the "Go/No-Go" iPad based executive function tasks (giving a measure of change in brain activity associated with doing the executive function tasks).

Efficacy
Statistical methods / analysis
As this study is a pilot feasibility trial we will aim to recruit up to 140 children. Allowing for an approximate drop out rate of 30% will result in up to 100 children completing the trial and 50 per group. We anticipate that this will be enough to detect trends in the data, which then can be used for subsequent power calculations for a larger adequately powered clinical trial.

Summary
Brief summary
The aim of the Omega Kid Study is to investigate the effect of omega-3 supplementation on behavioural outcomes such as self-regulation and executive function in preschool aged children. The study is parallel in design and placebo controlled with the intervention period lasting 12 weeks. Assessments will be conducted at baseline and at 12 weeks, after the intervention period. It is hypothesised that children who receive an active omega-3 supplement will show improvements in self-regulation and executive function, when compared to a matched placebo control group.
