摘要：本文用完全随机设计，观察了９１例正常孕妇不同孕期血和３７例新生儿脐血的ＬＰＯ、ＳＯＤ、ＶＥ和总胆固醇水平，并以２７例正常非孕妇作对照分析。结果表明：不同孕期孕妇血中的ＬＰＯ、ＳＯＤ、ＶＥ及总胆固醇水平都显著高于非孕妇，并随妊娠进展呈进行性上升；新生儿脐血的该四项指标均显著低于母血；非孕妇和脐血的ＬＰＯ、ＳＯＤ水平接近，而脐血的ＶＥ和总胆固醇水平显著低于非孕妇。该结果对妊娠及分娩后的母婴营养保健工作具有指导意义。

摘要：Objective: To assess the relationship between plasma leptin concentration during third trimester of pregnancy and blood pressure, independent of body mass index at examination and other potential confounders. Study design: A cross-sectional study was performed including 95 women [61 non-diabetic women, 34 women with gestational diabetes (GD)] in their third trimester of pregnancy. The relationship between plasma leptin and blood pressure was investigated using multiple linear regression analysis. Results: Independent of body mass index (BMI), leptin was positively correlated to systolic (P = 0.024) and diastolic blood pressure (P = 0.002). Stepwise linear regression identified leptin as the only variable independently associated with systolic blood pressure (P = 0.003), while leptin (P < 0.001) and age (P = 0.024) were the only variables independently correlated to diastolic blood pressure. Conclusions: This study reports for the first time that, independent of BMI at examination, presence of GD or other confounders, plasma leptin is positively correlated with blood pressure in pregnant women.
