Abstract:
Objective:To investigate the effects of gestational diabetes mellitus (GDM) on neonatal metabolites.Methods:This retrospective cohort study recruited 580 singleton newborns who were born to women with GDM from January 2018 to December 2018 in Foshan Maternal and Child Health Care Hospital as the GDM group. Another 580 counterparts born to non-GDM singleton mothers with matching age were selected as the non-GDM group with an allocation ratio of 1 to 1. Neonatal genetic metabolic disease screening was performed within 3-7 days after birth. Two independent sample t-test, and multiple linear regression model were used for statistical analysis. Results:There were significant differences in seven amino acids and 10 fatty acids levels between the GDM and non-GDM group. The serum levels of six amino acids and eight fatty acids were increased in the GDM group, while the levels of piperamide [(140.79±32.60) vs (150.26±35.46) μmol/L, t=－4.733, P<0.001], palmitoyl carnitine [(2.59±0.81) vs (2.73±0.82) μmol/L, t=－2.940, P=0.003], and carbamate [(0.066±0.022) vs (0.069±0.022) μmol/L, t=－1.937, P=0.042] were decreased compared with the non-GDM group. After adjusting for maternal gravidity, parity, neonatal birth weight, and gender, multivariate linear regression analysis showed that GDM was positively correlated with three amino acids levels, which were cysteine ( ?=0.012), homocysteine ( ?=0.263) and leucine ( ?=4.225); and was negatively correlated with glycine ( ?=－6.271) and piperamide level ( ?=－9.885). With regard to the fatty acids, GDM was positively correlated with the neonatal propionyl carnitine ( ?=0.214), butyryl carnitine ( ?=0.014), 3-hydroxybutyryl carnitine ( ?=0.006), isovaleryl carnitine ( ?=0.009), 3-hydroxyisovaleryl carnitine ( ?=0.024), hexadecanoyl carnitine ( ?=0.001), decadienoyl carnitine ( ?=0.045), octadecadienyl carnitine level ( ?=0.128), but was negatively correlated with palmitoyl carnitine ( ?=－0.119), and carbamate ( ?=－0.002) (all P<0.05). Conclusions:Correlations between maternal GDM and the levels of amino acids and fatty acids in neonates was noted in this study, suggesting that maternal GDM may affect the metabolism of amino acids and fatty acids in offspring at early stage of life.
