摘要:
目的 了解自然流产(spontaneous abortion, SA)患者的复合体质特点, 探索育龄女性发生SA的风险因素, 为SA的预防提供参考。 方法 收集2016年1月-2021年12月在成都市妇女儿童中心医院中医科就诊的育龄女性妊娠和中医体质信息, 辨识复合体质。采用单因素分析比较SA患者与非SA人群的主体质和兼夹体质的差异, 构建logistic回归模型探索SA的风险因素。 结果 纳入2 878例育龄女性信息, 其中759例具有SA史, 平均年龄32.34岁, 平和质仅占11.86%, 少于非SA人群(χ2=4.059, P=0.044)。SA患者主体质为特禀质的比例多于非SA人群(χ2=8.542, P=0.003), 且复合体质中含气虚质(χ2=5.113, P=0.024)和阳虚质(χ2=5.724, P=0.017)比例均高于非SA人群。SA患者偏颇体质存在聚集性。年龄增长、阳虚体质和特禀体质均是SA发生的风险因素。 结论 SA患者复合体质中气虚质和阳虚质的比例高于非SA人群, 且阳虚、气郁和气虚质显示出聚集性, 年龄、阳虚质和特禀质是SA的风险因素, 提示临床实践中对于有备孕需求的阳虚质和特禀质女性应及早进行体质调整, 预防自然流产。 Abstract:Objective To understand the compound constitution characteristics of patients with spontaneous abortion (SA), to explore the risk factors of SA in women of childbearing age, and to provide reference for the prevention of SA. Methods The information of pregnancy and traditional Chinese Medicine (TCM) constitution of childbearing age women who visited the TCM Department of Chengdu Women's and Children's Central Hospital in January 2016 to December 2021 were collected, and their compound constitutions were identified.Univariate analysis was used to compare the differences of major and concurrent constitutions between SA patients and non-SA people, and logistic regression model was established to explore the risk factors of SA. Results A total of 2 878 childbearing age women were included, and 759 of them had a history of SA, with an average age of 32.34, and only 11.86% of them were of balanced constitution, which was less than that of non-SA people (χ2=4.059, P=0.044).The proportion of SA patients with special intrinsic constitution was higher than that of non-SA people (χ2=8.542, P=0.003), and the compound constitutions containing Qi-deficiency (χ2=5.113, P=0.024) and Yang-deficiency constitution (χ2=5.724, P=0.017) were higher than non-SA population.The biased constitutions of SA patients were aggregative.Age growth, Yang-deficiency and Special Intrinsic constitutions were the risk factors of SA. Conclusion The proportions of Qi-deficiency and Yang-deficiency as compound constitutions in SA patients are higher than those in non-SA population, and Yang-deficiency, Qi-depression and Qi-deficiency show aggregation.Age, Yang-deficiency and special intrinsic constitutions are the risk factors of spontaneous abortion.It is suggested in clinical practice to adjust the constitution of preparing pregnant women when with Yang-deficiency and special intrinsic constitutions as soon as possible to prevent spontaneous abortion. -
