摘要:
目的 探讨不同孕前体重指数(body mass index,BMI)孕妇孕早期凝血及纤溶功能与妊娠期糖尿病(gestational diabetes,GDM)发生的相关性。 方法 选取2023年9月至2024年2月到昆明医科大学第二附属医院产检的290例孕妇,收集孕前BMI、年龄、家族遗传史、孕次、产次及孕早期凝血及纤溶功能检查结果。根据是否发生GDM分为GDM组(n = 72)及非GDM组(n = 218),根据孕前BMI分为低体重GDM组(n = 8)、低体重非GDM组(n = 29)、正常体重GDM组(n = 39)、正常体重非GDM组(n = 145)、超重/肥胖GDM组(n = 25)、超重/肥胖非GDM组(n = 44),定量资料采用独立样本t检验或Mann-Whitney U 检验,定性资料采用χ2检验或Fisher确切概率法,采用多因素Logistic回归校正影响因素。 结果 总人群中校正年龄、家族史以及孕前BMI后活化部分凝血活酶时间(APTT)与GDM发生呈负相关(P < 0.05,OR = 0.840),纤维蛋白原(FIB)与GDM呈正相关(P < 0.01,OR = 2.598)。在低体重组,APTT与GDM呈负相关(P < 0.05,OR = 0.483)、FIB与GDM呈正相关(P < 0.05,OR = 82.501),而校正年龄、家族史、孕前BMI后APTT、FIB与GDM无明显相关性;在正常体重组,APTT与GDM呈负相关(P < 0.01,OR = 0.786)、FIB与GDM呈正相关(P < 0.05,OR = 2.413),而校正年龄、家族史、孕前BMI后APTT与GDM仍呈负相关(P < 0.05,OR = 0.812)、FIB与GDM仍呈正相关(P < 0.05,OR = 2.391);在超重/肥胖组中,凝血酶时间(TT)与GDM呈负相关(P < 0.05,OR = 0.510),校正年龄、家族史、孕前BMI后TT与GDM无明显相关性。 结论 在正常体重人群中,APTT与GDM发生呈负相关,FIB与GDM发生呈正相关;在低体重与超重/肥胖人群中,凝血及纤溶相关指标受BMI影响较大,与GDM发生无明显相关性。 -

Abstract:Objective To explore the relationship between the coagulation and fibrinolysis function in the early pregnancy and the occurrence of gestational diabetes mellitus (GDM) in women with different pre pregnancy body mass indexes (BMI). Methods 290 pregnant women undergoing the prenatal check ups at the Second Affiliated Hospital of Kunming Medical University from September 2023 to February 2024 were selected. Pre pregnancy BMI, age, family genetic history, parity, parity, and early pregnancy coagulation and fibrinolysis function test results were collected. Based on whether GDM had occurred, they were divided into GDM group (n = 72) and non GDM group (n = 218), and further divided into low weight GDM group (n = 8), low weight non GDM group (n = 29), normal weight GDM group (n = 39), normal weight non GDM group (n = 145), overweight/obesity GDM group (n = 25), overweight/obesity non GDM group (n = 44) based on pre pregnancy BMI. Basic data comparison was conducted on the total population and BMI groups. Independent sample t-test or Mann Whitney U test was used for quantitative data, and chi square test or Fisher's exact probability method was used for qualitative data. Multivariate logistic regression was used to correct the influencing factors. Results After adjusting the confounding factors such as age, family history, and pre pregnancy BMI, APTT was negatively correlated with the occurrence of GDM in the overall population (P < 0.05, OR = 0.840), while FIB was positively correlated with GDM (P < 0.01, OR = 2.598). In low body weight recombination, APTT was negatively correlated with GDM (P < 0.05, OR = 0.483), FIB was positively correlated with GDM (P < 0.05, OR=82.501), while there was no significant correlation between APTT, FIB and GDM after adjusting the age, family history, and pre pregnancy BMI; In the normal weight group, APTT was negatively correlated with GDM (P < 0.01, OR = 0.786) and FIB was positively correlated with GDM (P < 0.05, OR = 2.413). However, after adjusting the age, family history, and pre pregnancy BMI, APTT remained negatively correlated with GDM (P < 0.05, OR = 0.812) and FIB remained positively correlated with GDM (P < 0.05, OR = 2.391); In the overweight/obese group, TT was negatively correlated with GDM (P < 0.05, OR = 0.510), while there was no significant correlation between TT and GDM after adjusting the age, family history, and pre pregnancy BMI. Conclusion In the normal weight population, APTT is negatively correlated with the occurrence of GDM, while FIB is positively correlated with the occurrence of GDM; In the low weight and overweight/obese populations, coagulation and fibrinolysis related indicators are greatly influenced by BMI and have no significant correlation with the occurrence of GDM. -
