BackgroundEnvironmental influences during pregnancy are able to affect off spring phenotype with lifelong effects. Clinical applicable markers are needed to identify foetuses at risk for neonatal adiposity. This systematic review aims to 1) review the current literature on prenatal markers of neonatal fat mass, and 2) appraise the clinical applicability of the assessed markers.MethodsA systematic literature search was conducted to identify studies meeting the following inclusion criteria: 1) original research papers in English; 2) research on dynamic and measurable prenatal markers of neonatal fat mass; 3) neonatal fat mass measurement within one month after birth, using the four-compartment model, magnetic resonance imaging, dual-energy X-ray absorptiometry or air displacement plethysmography. Two reviewers independently performed study selection, assessment of methodological (QUADAS-II) and statistical quality and appraisal of clinical applicability.ResultsOf 2333 studies primarily identified by the search strategy, 16 studies were included. Four of these were both methodologically and statistically of moderate or high quality. Prenatal markers investigated were ultrasound parameters, maternal biochemical markers and maternal characteristics. Markers of predefined interest were maternal pre-pregnancy body mass index, fasting glucose and HbA1c, showing varying results. A meta-analysis was not possible due to substantial methodological heterogeneity. Clinically applicability of all markers was rated poor.ConclusionsAlthough associations were found, no useful marker was identified, due to lack of methodological and statistical quality, inconsistent results and poor clinical applicability. No markers were investigated in the periconceptional and embryonic period.Copyright © 2015 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism. All rights reserved.
