Brief summary
The primary objective of this study is to obtain preliminary (pilot) data regarding the feasibility of using dietary omega-3 supplementation in children with significant delays in language skills; a related secondary objective is to compare adherence to a dosage schedule of two easy-to-take formulations. A tertiary objective of this study is to collect preliminary (pilot) data pre- and post-supplementation to identify potential improvement of skills in a specific area of language development.
Detailed description
HYPOTHESIS Hypothesis 1: Children with early developmental impairment in language will successfully take daily omega-3 fatty acid supplementation for a well-defined period of time (3 months); Hypothesis 2: Children with early developmental impairment will better adhere to administration of a small quantity of slightly fishy-tasting oil than to a large quantity of sweet-tasting paste; Hypothesis 3: A 3 month period of daily omega-3 supplementation will produce some improvement in fast-mapping language skills (a dynamic vocabulary learning skill that has been shown to rapidly improve after exposure to beneficial intervention).
Interventions
DIETARY_SUPPLEMENTOmega-3
800 mg Omega 3 daily (600 mg DHA/200 mg EPA)
DIETARY_SUPPLEMENTPlacebo
Placebo is a combination of dietary plant-based oils in a paste containing no Omega-3 (EPA or DHA)

Inclusion criteria
* children in the chronological age range of 24 to 42 months at the time of initial assessment * diagnosis of expressive, receptive or mixed language impairment (LI) by a certified Speech-Language Pathologist (S-LP) * ability to take daily omega-3 supplementation (with caregiver assistance)
Exclusion criteria
* children with any organic disease processes or genetic syndromes, or known developmental disorders such as autism that may present with language impairment * children with hearing impairment * children who take any non-standard dietary supplements (i.e., apart from multi-vitamins), particularly any omega-3 FA, prior to starting the study * children whose parents do not have an adequate understanding of English or French
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change over 3 months in learning assessed by a fast-mapping task | Assessed at time of diagnosis and 3 months after intervention | A simple fast-mapping task, which is a measure of language learning used widely in linguistics research, will be performed in the pre and post-intervention period. We will present a list of non-words selected with only early-developing sounds to ensure that they are within the repertoire of developmentally impaired children. Scores are calculated in terms of number of items successfully completed. An initial and final assessment of dynamic language learning will be done as an addendum to scores on standardized language tests that establish a language impairment diagnosis. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Feasibility of fish oil vs. chewable Concordix paste | Given for 3 months as intervention | In order to estimate the relative success of administering paste vs. oil in relation to omega-3 vs. placebo, a repeated measures ANOVA will be used to test for significant differences. The primary measure will be parental report as easy vs. difficult to administer, and the analysis will be run as Between group (paste vs. oil) by Treatment arm (omega-3 vs. placebo) by Adminstration success (easy vs. difficult). |
