Abstract

Objectives: To find out whether supplementation of formula milk by long-chain polyunsaturated fatty acids (LCPUFA) affects neurodevelopment at 18 months of age in term or preterm infants by an individual patient data (IPD) meta-analysis.

Materials and Methods: Data of 870 children from 4 large randomised clinical trials for formula milk with and without LCPUFAs allowed for assessing the effect of LCPUFA with adjustment For potential confounders and extensive subgroup analysis on prematurity, LCPUFA Source, and dosage. Any additional clinical trials examining the effect of LCPUFA supplementation on Bayley Scales of Infant Development at 18 months were regarded as relevant. Two relevant studies were identified by MEDLINE, but were not available to us. An IPD meta-analysis was performed with Subgroup analyses by preterm delivery, very low birth weight (

Results: There were no significant differences in mental or psychomotor developmental indexes between LCPUFA-supplemented and control groups for all children or in Subgroups. This was confirmed with adjustment for the possible confounders: sex, gestational age, birth weight, maternal age, and maternal smoking. The adjusted mean differences in mental developmental index and psychomotor developmental index for all of the children were -0.8 (95% confidence interval -2.8 to 1.2) and -1.0 (-2.7 to 0.7), respectively.

Conclusions: These data based on considerable sample size Provide evidence that LCPUFA supplementation of infant formula does not have a clinically meaningful effect on the neurodevelopment as,assessed by Bayley scores at 18 months. Inclusion of all relevant data should not have led to differing conclusions except, possibly, for very-low-birth-weight infants.
