Abstract:
Objective:To explore the correlation between the total cholesterol/high-density lipoprotein cholesterol (TC/HDL-C) ratio during pregnancy and the onset of gestational metabolic syndrome (GMS), as well as its association with pregnancy outcomes.Methods:Clinical data of 153 pregnant women diagnosed with GMS in the third trimester admitted to Women′s Hospital of Nanjing Medical University from January 2020 to December 2022 (observation group) were collected, and data of 153 healthy pregnant women (control group) were randomly selected for a comparative study. Indicators of the two groups were observed and compared. Multiple linear regression and restricted cubic spline analysis were used to analyze the correlation between TC/HDL-C in the first and second trimesters and metabolic indicators in the third trimester and GMS risk, respectively. According to the pregnancy outcomes of GMS pregnant women with different TC/HDL-C ratios, the association between TC/HDL-C ratio and preterm birth subtypes was analyzed.Results:There were statistically significant differences between the two groups in age, gestational week, pre-pregnancy body mass index (BMI), weight gain during pregnancy, abdominal circumference in the third trimester, whether to deliver vaginally, history of preterm birth, history of cesarean section, history of abortion, neonatal birth weight, and neonatal length (all P<0.05). There were statistically significant differences in blood pressure and BMI between the two groups in the second and third trimesters (all P<0.01). In the first trimester (gestational week <14 weeks), there were statistically significant differences in fasting plasma glucose (FPG), HDL-C, and TC/HDL-C ratio between the two groups (all P<0.05). In the second trimester (gestational weeks 14-27) and third trimester (gestational week ≥28 weeks), the levels of FPG, fasting insulin (FINS), triglyceride (TG), TC, low-density lipoprotein cholesterol (LDL-C), and TC/HDL-C ratio in the observation group were higher than those in the control group, while HDL-C was lower (all P<0.05). There were statistically significant differences between the two groups in postpartum abnormal blood pressure, abnormal BMI, abnormal glucose metabolism, and abnormal lipid metabolism (all P<0.05). After adjusting for age, gestational week, and BMI, first-trimester TC/HDL-C ratio was correlated with third-trimester FPG, systolic blood pressure, diastolic blood pressure, TG, TC, and HDL-C (all P<0.05); second-trimester TC/HDL-C ratio was correlated with third-trimester FPG, FINS, systolic blood pressure, diastolic blood pressure, TG, TC, HDL-C, and LDL-C (all P<0.05), and both were linearly related to third-trimester GMS risk ( Pfor trend<0.01). The TC/HDL-C ratio was positively correlated with the preterm birth rate ( RR>1). Conclusions:An increased TC/HDL-C ratio is closely related to the occurrence of GMS, which is prone to cause preterm birth and affect fetal growth and development.
