Sanz N, et al. - In this longitudinal pilot study, researchers assessed circulating polyunsaturated fatty acid (PUFA) levels in maternal, cord, and peripheral blood at 6 years of age via gas chromatography, and examined their link with body composition and endocrine-metabolic variables (at age 6 years) via absorptiometry. The study sample consisted of 16 apparently healthy children born appropriate for gestational age and followed longitudinally since birth. According to findings, maternal, cord blood, and circulating PUFA in children do not appear to affect body composition and endocrine-metabolic status at 6 years of age. The close association at that age between maternal PUFA and offspring PUFA may reflect similarities in mother and child nutritional habits.
