Background/Objectives: Long-chain polyunsaturated fatty acids (LCPUFA) rapidly accumulate in the central nervous system (CNS) during the perinatal CNS growth spurt. This particularly concerns arachidonic acid (AA: 20:4n-6) and docosahexaenoic acid (DHA: 22:6n-3), which are thought to play important roles in CNS development and function. The aim of this study was to investigate the relation between motor function at 7 years of age and the levels of AA and DHA in umbilical venous plasma phospholipids, representing the prenatal availability of these fatty acids, and in plasma phospholipids sampled at age 7 years. Subjects/Methods: Motor function was assessed both quantitatively (the ability to perform a movement) and qualitatively (how the movement is performed) with the Maastricht Motor Test (MMT) in 306 children, born at term, at 7 years of age as part of a follow-up study. Results: Backward stepwise multiple regression analyses revealed a significant, positive relation between umbilical plasma DHA concentrations (but not plasma DHA levels at 7 years) and the MMT total and quality score, corrected for the covariables gender, cognitive performance, gestational age and age at measurement (partial beta = 0.13, P = 0.01 and 0.14, P = 0.01, respectively). The contributions of DHA and AA (both at birth and at 7 years of age) to quantitative movement scores were not significant. Conclusions: Our results suggest that prenatal DHA availability, which can be influenced by maternal dietary DHA intake during pregnancy, can have an effect on quality of movement in later life.
