Developmental Outcomes at 24 Months of Age in Toddlers Supplemented with Arachidonic Acid and Docosahexaenoic Acid: Results of a Double Blind Randomized, Controlled Trial.

ABSTRACT: Little is known about arachidonic acid (ARA) and docosahexaenoic acid (DHA) requirements in toddlers. A longitudinal, double blind, controlled trial in toddlers ( n = 133) age 13.4 ± 0.9 months (mean ± standard deviation), randomized to receive a DHA (200 mg/day) and ARA (200 mg/day) supplement (supplement) or a corn oil supplement (control) until age 24 months determined effects on neurodevelopment. We found no effect of the supplement on the Bayley Scales of Infant and Toddler Development 3rd Edition (Bayley-III) cognitive and language composites and Beery-Buktenica Developmental Test of Visual-Motor Integration (Beery VMI) at age 24 months. Supplemented toddlers had higher RBC phosphatidylcholine (PC), phosphatidylethanolamine (PE), and plasma DHA and ARA compared to placebo toddlers at age 24 months. A positive relationship between RBC PE ARA and Bayley III Cognitive composite (4.55 (0.21-9.00), B (95% CI), p = 0.045) in supplemented boys, but not in control boys, was observed in models adjusted for baseline fatty acid, maternal non-verbal intelligence, and BMI z-score at age 24 months. A similar positive relationship between RBC PE ARA and Bayley III Language composite was observed for supplemented boys (11.52 (5.10-17.94), p < 0.001) and girls (11.19 (4.69-17.68), p = 0.001). These findings suggest that increasing the ARA status in toddlers is associated with better neurodevelopment at age 24 months.

Project description:Study objectivesThis secondary analysis characterized sleep patterns for toddlers born preterm and tested effects of docosahexaenoic acid (DHA)+ arachidonic acid (AA) supplementation on children's caregiver-reported sleep. Exploratory analyses tested whether child sex, birth weight, and caregiver depressive symptomatology were moderators of the treatment effect.MethodsOmega Tots was a single-site 180-day randomized (1:1), double-blinded, placebo-controlled trial. Children (n = 377) were age 10 to 16 months at enrollment, born at less than 35 weeks' gestation, assigned to 180 days of daily 200 mg DHA + 200 mg AA supplementation or placebo (400 mg corn oil), and followed after the trial ended to age 26 to 32 months. Caregivers completed a sociodemographic profile and questionnaires about their depressive symptomatology (Center for Epidemiologic Studies Depression Scale) and the child's sleep (Brief Infant Sleep Questionnaire). Analyses compared changes in sleep between the DHA+AA and placebo groups, controlling for baseline scores. Exploratory post hoc subgroup analyses were conducted.ResultsEighty-one percent (ntx = 156; nplacebo = 150) of children had 180-day trial outcome data; 68% (ntx = 134; nplacebo = 122) had postintervention outcome data. Differences in change between the DHA+AA and placebo groups after 180 days of supplementation were not statistically significant for the entire cohort. Male children (difference in nocturnal sleep change = 0.44, effect size = 0.26, P = .04; sleep problems odds ratio = 0.36, 95% confidence interval = 0.15, 0.82) and children of depressed caregivers (difference in nocturnal sleep change = 1.07, effect size = 0.65, P = .006; difference in total sleep change = 1.10, effect size = 0.50, P = .04) assigned to the treatment group showed improvements in sleep, compared to placebo.ConclusionsAlthough there is no evidence of an overall effect of DHA+AA supplementation on child sleep, exploratory post hoc analyses identified important subgroups of children born preterm who may benefit.

Project description:BackgroundDietary DHA intake among US toddlers is low. Healthy physical growth is an important objective for the clinical care of children born preterm.ObjectivesThe aim of the trial was to examine the effects of supplementing toddlers born preterm with DHA and arachidonic acid (AA) for 180 d on growth and adiposity.MethodsOmega Tots, a randomized placebo-controlled trial, was conducted between April 2012 and March 2017. Children born at <35 wk gestation who were 10-16 mo in corrected age were assigned to receive daily oral supplements of DHA and AA (200 mg each, "DHA + AA") or corn oil (placebo) for 180 d. Prespecified secondary outcomes included weight, length, head circumference, mid-upper arm circumference, triceps and subscapular skinfolds, BMI, and their respective z scores, and body fat percentage, which were measured at baseline and trial completion. Mixed-effects regression was used to compare the change in outcomes between the DHA + AA and placebo groups, controlling for baseline values.ResultsAmong 377 children included in the analysis (median corrected age = 15.7 mo, 48.3% female), 348 (92.3%) had growth or adiposity data at baseline and trial end. No statistically significant differences between the DHA + AA and placebo groups in growth or adiposity outcomes were observed. For instance, the change in weight-for-age z scores was 0.1 for the DHA + AA group and 0.0 for the placebo group (effect size = 0.01, P = 0.99). However, post-hoc subgroup analyses revealed a statistically significant interaction between treatment group and sex, suggesting somewhat slower linear growth for females assigned to the DHA + AA group compared with the placebo group.ConclusionsAmong toddlers born preterm, daily supplementation with DHA + AA for 180 d resulted in no short-term differences in growth or adiposity compared with placebo. If DHA supplementation is implemented after the first year of life, it can be expected to have no effect on short-term growth or adiposity. This trial is registered with clinicaltrials.gov as NCT02199808.

Project description:ImportanceIntake of dietary docosahexaenoic acid (DHA) among toddlers is low. Supplementation may benefit developmental outcomes of toddlers who were born preterm.ObjectiveTo determine whether 6 months of daily DHA supplementation improves developmental outcomes of toddlers who were born preterm.Design, setting, and participantsA randomized, fully masked, placebo-controlled trial was conducted from April 26, 2012, to March 24, 2017, at a large US pediatric academic center with 9 neonatal intensive care units. Children born at less than 35 weeks' gestation who were 10 to 16 months corrected age underwent 6 months of intervention. Of 2363 children assessed, 982 were eligible, 605 declined, and 377 enrolled and were randomized. Analyses were according to intent to treat.InterventionsOne-to-one allocation to receive daily microencapsulated DHA, 200 mg, and arachidonic acid (AA), 200 mg (DHA+AA), or microencapsulated corn oil (placebo).Main outcomes and measuresThe primary outcome specified a priori was Bayley Scales of Infant and Toddler Development, third edition (Bayley-III), cognitive composite score at 16 to 22 months corrected age. Secondary outcomes were Bayley-III language and motor composite scores and Infant Behavior Questionnaire-Revised and Early Childhood Behavior Questionnaire effortful control and activity level scores. Subgroup analyses defined a priori were by income, sex, and birth weight.ResultsAmong 377 children randomized and included in the analysis (182 girls and 195 boys; median corrected age, 15.7 months), 338 children (89.7%) had complete data on the primary outcome. Bayley-III cognitive scores did not differ between the DHA+AA and placebo groups (difference in change, 0.5 [95% CI, -1.8 to 2.8]; effect size, 0.05; P = .66). Assignment to the DHA+AA group had a small to medium negative effect on Bayley-III language scores among children with lower birth weights (eg, a child with a birth weight of 1000 g assigned to receive DHA+AA experienced a 4.1-point relative decrease, while a child assigned to placebo did not; P = .03 for interaction). Supplementation had a similar negative effect on effortful control scores among children with annual household incomes greater than $35 000 (difference in change, -0.3 [95% CI, -0.4 to -0.1]; effect size, -0.37; P = .01). Bayley-III motor scores and activity level scores were unaffected.Conclusions and relevanceDaily supplementation with 200 mg of DHA and 200 mg of AA for 6 months resulted in no improvement in cognitive development and early measures of executive function vs placebo, and may have resulted in negative effects on language development and effortful control in certain subgroups of children. These findings do not support DHA supplementation in the second year of life for children who are born preterm.Trial registrationClinicalTrials.gov Identifier: NCT01576783.
