title: Relation between abdominal subcutaneous fat tissue thickness and inflammatory markers during pregnancy.
abstract: BACKGROUND
  Subcutaneous abdominal fat thickness (SCFT) is important for predisposition to metabolic and cardiovascular diseases. Our aim was to evaluate maternal SCFT and metabolic changes (such as insulin resistance and high inflammatory markers) during pregnancy.
  
  
  METHODS
  A total of 92 pregnant women between 24-28 weeks of gestation were enrolled in the study. The SCFT was measured by ultrasonography and patients were divided into 2 groups according to thickness of maternal SCFT and body mass index (BMI). Groups were compared with each other for oral glucose loading test (OGL) results, and for haematological, biochemical and fetal biometric parameters.
  
  
  RESULTS
  After analysis of frequency for SCFT, the most appropriate cut-off value for grouping patients was found to be 15 mm for SCFT. In 48 cases SCFT was over 15 mm. High C reactive protein (CRP) was found in 47.9% (23) of cases with SCFT over 15 mm. Serum haemoglobin A1c (HbA1c) level was significantly correlated with SCFT thickness. The most important factors for determination of OGL level were found to be serum HbA1c level, BMI and SCFT. In obese subjects (BMI ≥ 25 kg/m(2)), levels of inflammatory markers and SCFT thickness were higher. The CRP and γ-glutamyltransferase (GGT) levels were significantly correlated with BMI and SCFT.
  
  
  CONCLUSIONS
  High SCFT during pregnancy is associated with elevated inflammatory marker levels and HbA1c. Pregnant women with thicker SCFT may be susceptible to the development of metabolic complications of pregnancy, such as gestational diabetes mellitus (GDM) and hypertension, as well as risk of future metabolic and cardiovascular disease.
