目的:探讨妊娠期糖尿病(gestational diabetes mellitus,GDM)孕妇妊娠前体重指数(body mass index,BMI)与新生儿出生体重的关系。方法2012年5月1日至2013年11月1日,在北京大学第一医院产前检查并分娩的GDM孕妇中,本研究纳入年龄20~49岁的单胎妊娠孕妇550例。BMI≥24.0为超重组(145例),<24.0为非超重组(405例),比较2组的妊娠期增重、75 g口服葡萄糖耐量试验的血糖值、血糖控制情况、分娩方式以及新生儿出生体重。分析巨大儿的影响因素,以及妊娠前BMI与新生儿出生体重的关系。统计学方法采用独立样本t检验、χ2检验、多元Logistic回归及Pearson相关分析。采用受试者工作特性曲线分析妊娠前BMI预测巨大儿的阈值。结果妊娠前非超重组与超重组的空腹血糖分别为(5.1±0.5)与(5.3±0.5) mmol/L,服糖后1 h血糖分别为(9.4±1.7)与(9.8±1.6) mmol/L、血糖控制不达标的比例分别为20.5%(83/405)与33.1%(48/145)、剖宫产比例分别为37.8%(153/405)与55.2%(80/145)、新生儿平均出生体重分别为(3306±424)与(3476±545) g,巨大儿比例分别为5.4%(22/405)与16.6%(24/145),超重组均高于非超重组,差异有统计学意义(t或χ2值分别为-4.599、-2.742、8.281、13.160、-3.374与16.291,P值均<0.01)。超重组妊娠期每周平均增重低于非超重组[(336±123)与(402±131) g],差异有统计学意义(t=5.136,P<0.01)。妊娠前超重、妊娠期每周平均增重和空腹血糖是巨大儿的影响因素,OR(95%CI)分别为4.009(2.039~7.881)、1.003(1.001~1.005)和2.285(1.326~3.938)(P值均<0.01)。GDM孕妇妊娠前BMI与新生儿出生体重呈正相关(r=0.179,P<0.01)。受试者工作特性曲线下面积为0.691,妊娠前BMI≥22.8时预测巨大儿的效果最好。结论 GDM孕妇妊娠前超重是分娩巨大儿的危险因素。妊娠前超重者如果诊断GDM,建议妊娠期合理控制血糖及妊娠期增重,以降低巨大儿的发生风险。
目的:探討妊娠期糖尿病(gestational diabetes mellitus,GDM)孕婦妊娠前體重指數(body mass index,BMI)與新生兒齣生體重的關繫。方法2012年5月1日至2013年11月1日,在北京大學第一醫院產前檢查併分娩的GDM孕婦中,本研究納入年齡20~49歲的單胎妊娠孕婦550例。BMI≥24.0為超重組(145例),<24.0為非超重組(405例),比較2組的妊娠期增重、75 g口服葡萄糖耐量試驗的血糖值、血糖控製情況、分娩方式以及新生兒齣生體重。分析巨大兒的影響因素,以及妊娠前BMI與新生兒齣生體重的關繫。統計學方法採用獨立樣本t檢驗、χ2檢驗、多元Logistic迴歸及Pearson相關分析。採用受試者工作特性麯線分析妊娠前BMI預測巨大兒的閾值。結果妊娠前非超重組與超重組的空腹血糖分彆為(5.1±0.5)與(5.3±0.5) mmol/L,服糖後1 h血糖分彆為(9.4±1.7)與(9.8±1.6) mmol/L、血糖控製不達標的比例分彆為20.5%(83/405)與33.1%(48/145)、剖宮產比例分彆為37.8%(153/405)與55.2%(80/145)、新生兒平均齣生體重分彆為(3306±424)與(3476±545) g,巨大兒比例分彆為5.4%(22/405)與16.6%(24/145),超重組均高于非超重組,差異有統計學意義(t或χ2值分彆為-4.599、-2.742、8.281、13.160、-3.374與16.291,P值均<0.01)。超重組妊娠期每週平均增重低于非超重組[(336±123)與(402±131) g],差異有統計學意義(t=5.136,P<0.01)。妊娠前超重、妊娠期每週平均增重和空腹血糖是巨大兒的影響因素,OR(95%CI)分彆為4.009(2.039~7.881)、1.003(1.001~1.005)和2.285(1.326~3.938)(P值均<0.01)。GDM孕婦妊娠前BMI與新生兒齣生體重呈正相關(r=0.179,P<0.01)。受試者工作特性麯線下麵積為0.691,妊娠前BMI≥22.8時預測巨大兒的效果最好。結論 GDM孕婦妊娠前超重是分娩巨大兒的危險因素。妊娠前超重者如果診斷GDM,建議妊娠期閤理控製血糖及妊娠期增重,以降低巨大兒的髮生風險。

Objective To explore the relationship between maternal pre-pregnancy body mass index (BMI) and neonatal birth weight in women with gestational diabetes mellitus (GDM). Methods From the pregnant women who received prenatal care and delivered at the Department of Obstetrics and Gynecology of Peking University First Hospital between May 1, 2012 and November 1, 2013, 550 GDM women aged 20-49 years and with single gestation were enrolled in this study. According to the pre-pregnancy BMI, the GDM women were divided into overweight group (BMI ≥ 24.0, n=145) and non-overweight group (BMI < 24.0, n=405). Gestational weight gain, glucose level of 75 g oral glucose tolerance test, glucose control, delivery mode and neonatal birth weight were compared between the two groups. The influencing factors for macrosomia and the relationship between maternal pre-pregnancy BMI and neonatal birth weight were analyzed. Independent sample t-test, Chi-square test, multivariate Logistic regression and Pearson correlation analysis were used for statistical analysis. Receiver operating characteristic (ROC) curve was used to determine the optimal threshold of pre-pregnancy BMI to predict macrosomia. Results Compared with the data of non-overweight group, fasting glucose level [(5.1±0.5) vs (5.3±0.5) mmol/L, t=-4.599], 1 h glucose level [(9.4±1.7) vs (9.8±1.6) mmol/L, t= - 2.742], proportion of poor glucose control [20.5% (83/405) vs 33.1% (48/145), χ2=8.281], proportion of cesarean delivery [37.8% (153/405) vs 55.2% (80/145), χ2=13.160], neonatal birth weight [(3 306±424) vs (3 476±545) g, t=-3.374], and ratio of macrosomia [5.4% (22/405) vs 16.6% (24/145), χ2=16.291] were all higher in overweight group (all P < 0.01). The mean gestational weight gain per week in overweight group was significantly lower than in non-overweight group [(336±123) vs (402±131) g, t=5.136, P < 0.01]. Pre-pregnancy overweight (OR=4.009, 95%CI:2.039-7.881), gestational weight gain per week (OR=1.003, 95%CI:1.001-1.005) and fasting glucose level (OR=2.285, 95%CI: 1.326-3.938) were the influencing factors for macrosomia (all P < 0.01). Pre-pregnancy BMI of GDM women was positively related with neonatal birth weight (r=0.179, P < 0.01). Pre-pregnancy BMI ≥ 22.8 was defined as the optimal threshold to predict macrosomia (ROC area under curve=0.691). Conclusions Maternal pre-pregnancy overweight is a significant risk factor for macrosomia in women with GDM. GDM women with pre-pregnancy overweight should control glucose level and weight gain during pregnancy in order to reduce the risk of macrosomia.
