The effect of metabolic syndrome and its components in midpregnancy on neonatal outcomes

BackgroundThe prevalence of metabolic syndrome has been rising worldwide in recent decades. Determining the associations between metabolic syndrome and its components in midpregnancy with neonatal anthropometric indices and outcomes is a major challenge in both public health and clinical care.  MethodsThis prospective cohort study was performed on 238 pregnant women at 24-28 weeks of gestation. Metabolic syndrome was recognized with 3 or more of the following criteria: triglyceride ≥ 247 mg/dL; HDL < 61 mg/dL; GCT ≥ 140 mg/dL; prepregnancy body mass index ≥ 30 kg/m2; and blood pressure ≥ 130/85 mmHg. Statistical analysis was performed through descriptive statistics, including mean, standard deviation, frequency, and percentage, Mann-Whitney test, Chi-square test, Fisher’s exact test, linear and logistic regression in SPSS 21.0. P values < 0.05 were considered significant.  ResultsThere was a significant association between blood hypertriglyceridemia in weeks 24-28 and anthropometric indices, including weight, height, and jaundice, in the first 24 hours of birth. Metabolic syndrome also had a significant relationship with jaundice (P=0.002). The results of linear regression analysis revealed that metabolic syndrome was positively associated with birth weight (B=0.18, P=0.003) and height (B=0.18, P=0.009). Among the components of metabolic syndrome, the results showed a direct relationship between increased blood triglyceride of the mother and newborn’s weight (B=0.11, P=0.011) and height (B=0.14, P=0.007). Also, increased BMI had a significant direct relationship with the newborn’s weight (B=0.11, P=0.023) and height (B=0.12, P=0.023). Moreover, decreased HDL had a significant reverse relationship with the newborn’s weight (B=0.09, P=0.042).ConclusionPresence of metabolic syndrome and its components in midpregnancy may influence neonatal outcomes, especially anthropometric indices. However, more studies should be conducted to further investigate these relationships.
