Effects of Omega-3-6-9 fatty acid supplementation on behavior and sleep in preterm toddlers with autism symptomatology: Secondary analysis of a randomized clinical trial
Abstract
Background: Children born extremely preterm disproportionately experience sequelae of preterm birth compared to those born at later gestational ages, including higher prevalence of autism spectrum disorder (ASD) and associated behaviors. Aim: Explore effects of combined dietary docosahexaenoic acid, eicosapentaenoic acid, gamma-linolenic acid, and oleic acid (omega 3-6-9) on caregiver-reported behavior and sleep in toddlers born at ≤29 weeks' gestation who were exhibiting symptoms commonly seen with ASD. Study design: 90-day randomized (1:1), double blinded, placebo-controlled trial. Subjects: Thirty-one children aged 18–38 months received omega 3-6-9 (n = 15) or canola oil placebo (n = 16). Outcome Measures: Mixed effects regression analyses followed intent to treat and explored treatment effects on measures of caregiver-reported behavior (Child Behavior Checklist 1.5–5, Toddler Behavior Assessment Questionnaire – Short Form, Vineland Adaptive Behavior Scales, 2nd Edition) and sleep (Children's Sleep Habits Questionnaire, Brief Infant Sleep Questionnaire). Results: Twenty-nine of 31 (94%; ntx = 13, nplacebo = 16) children randomized had data available for at least one outcome measure, 27 (87%; ntx = 12, nplacebo = 15) had complete outcome data. Children randomized to omega 3-6-9 experienced a medium magnitude benefit of supplementation on anxious and depressed behaviors (ΔDifference = −1.27, d = −0.58, p = 0.049) and internalizing behaviors (ΔDifference = −3.41, d = −0.68,…
How strong is the evidence?
Evidence Hub reads this as a secondary / pooled analysis, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 16 participants or records.
