Aims: The aim of this study was to determine if maternal nutritional status, as defined by body composition, leptin, and insulin-like growth factor (IGF)-I levels, relates to foetal growth. Methods: In this prospective study, mothers of foetuses with foetal growth restriction (FGR; cases; n = 46) and mothers of appropriate-for-gestational-age (AGA) foetuses (controls; n = 81) were consecutively recruited over a 14-month period. A maternal blood sample was obtained during the third trimester (between 32 and 34 weeks of gestation) for the assessment of IGF-I and leptin. Body composition was assessed by dual-energy X-ray absorptiometry within the first 15 days after delivery. The study used the SPSS-PC statistical package, version 19.0, and p < 0.05 was considered statistically significant. Results: Mean serum IGF-I levels were lower in the cases than in the controls (p < 0.05), whereas leptin concentrations were higher in the cases after adjusting for age, body mass index and cigarette consumption (p < 0.05). Cases had less lean and fat tissue than controls (p < 0.05) but a relatively higher fat percentage. Conclusions: The mothers of foetuses with FGR have a body composition pattern characterized by a slightly increased fraction of fat mass, lower IGF-I concentrations, and increased serum leptin levels. Optimization of maternal nutritional status should be considered, as the nutritional status may be involved in the pathogenesis of FGR. (C) 2015 S. Karger AG, Basel
