OBJECTIVE : To evaluate the impact of a parenteral lipid emulsion containing fish oil compared with a soybean-oil based lipid emulsion on the cognitive outcome and behavior of preschool children with extremely low birth weight (ELBW) .
STUDY DESIGN : This was a retrospective secondary outcome analysis of a randomized controlled trial performed between 06/2012 and 06/2015. Infants with ELBW received either a mixed (soybean oil, medium chain triglycerides, olive oil, fish oil) or a soybean oil-based lipid emulsion for parenteral nutrition. Data from the Kaufman Assessment Battery for Children II (KABC-II), the Child Behavior Checklist 1.5-5 (CBCL 1.5-5), and anthropometry were collected from medical charts at 5.6 years of age.
RESULTS : At discharge, 206 of the 230 study participants were eligible. At 5 years, 6 months of age, data of 153 of 206 (74%) infants was available for analysis. There were no significant differences in KABC-II scores for Sequential/Gsm, Simultaneous/Gv, Learning/Glr, and Mental Processing Index (mixed lipid: median 97.5 [IQR 23.5]; soybean oil: median 96 [IQR 19.5], p=.43) or CBCL 1.5-5 scores for internalizing problems, externalizing problems, or total problems (mixed lipid: median 37 [IQR 12.3]; soybean oil: median 37 [IQR 13.5], p=.54). A Random Forest machine learning regression analysis did not show an effect of type of lipid emulsion on cognitive and behavioral outcome.
DISCUSSION : Parenteral nutrition using a mixed lipid emulsion containing fish oil did not affect neurodevelopment and had no impact on child behavior of infants with extremely low birth weights at preschool age.
