Abstract
BACKGROUND: Docosahexaenoic acid (DHA) has regulatory effects on lipid and glucose metabolism. Differences in DHA availability during specific developmental windows may program metabolic changes.
OBJECTIVE: We investigated the effects of maternal DHA supplementation during pregnancy on the nonfasting serum lipid and glucose concentrations of offspring at 4 y of age.
METHODS: We used data from the Prenatal Omega-3 Fatty Acid Supplementation, Growth, and Development trial, a double-blind randomized controlled trial conducted in Mexico. Pregnant women were supplemented daily with 400 mg DHA or placebo from 18-22 wk of gestation to delivery. The primary outcomes of the trial were offspring growth and neurological development. Nonfasting blood samples were obtained from the offspring at 4 y of age. We analyzed serum total, HDL, non-HDL, and LDL cholesterol; the total-to-HDL cholesterol ratio; apolipoprotein B (apoB); triglycerides; glucose; and insulin as secondary outcomes and compared their concentrations between treatment groups.
RESULTS: Data from 524 offspring were available. The women were compliant with the intervention based on pill counts and changes in cord blood and breast milk DHA concentrations. None of the between-group differences (DHA compared with placebo), adjusted for maternal height and time since last food intake, were significant (P range 0.27-0.83). Means (95% CIs) were as follows: total cholesterol (TC), 1.73 mg/dL (-2.63, 6.09 mg/dL); HDL cholesterol, 0.66 mg/dL (-1.07, 2.39 mg/dL); non-HDL cholesterol, 1.77 mg/dL (-1.83, 5.37 mg/dL); LDL cholesterol, 1.62 mg/dL (-2.21, 5.45 mg/dL); TC:HDL ratio, 0.01 (-0.09, 0.11); apoB, -0.15 mg/dL (-2.78, 2.48 mg/dL); triglycerides, 0.21 mg/dL (-10.93, 10.52 mg/dL); glucose, -0.67 mg/dL (-2.46, 1.11 mg/dL); and insulin, 0.62 μU/mL (-0.88, 2.11 μU/mL).
CONCLUSION: Prenatal DHA supplementation does not affect nonfasting serum lipid and glucose concentrations of offspring at 4 y of age. This trial was registered at clinicaltrials.gov as NCT00646360.
