A Study on the Correlation of Body Mass Management During Pregnancy with Adverse Pregnancy Outcomes and Labor Progression

Objective:To investigate the effects of body mass management during pregnancy on adverse pregnancy outcomes,duration of labor,and neonatal birth weight.Methods:472 pregnant women who visited Beijing Anzhen Hospital from January to December 2023 were selected,and the pregnant women were divided into 236 each in the observation group and the control group.Body mass of pregnant women was measured and BMI was calculated in early and late pregnancy respectively,and the pregnant women in the control group were guided by routine management,while the observation group was guided by body mass management during pregnancy.The growth of maternal body mass,mode of delivery,postpartum hemorrhage,neonatal score,neonatal blood glucose at birth,and umbilical artery blood,as well as the comparison of the duration of labor,were observed.Results:The observation group was significantly better than the control group in terms of mode of delivery,postpartum hemorrhage,and body mass growth,with statistically significant differences(P<0.05),and there was no statistical significance in terms of neonatal scores,neonatal blood glucose at birth,and umbilical artery blood(P>0.05);the time of the first stage of labor and the time of the second stage of labor of the mothers in the observation group was significantly better than that of the control group,with statistical differences(P<0.05),and the time of the third stage of labor of the mothers in the observation group was statistically better than that of the control group.There was no statistically significant difference between the time of the third stage of labor in the observation group and the control group(P>0.05),and the time of the total stage of labor in the observation group was statistically better than that in the control group(P<0.05).Conclusion:Body mass management during pregnancy can effectively improve maternal control of weight gain,reduce labor time,and decrease the occurrence of adverse pregnancy outcomes.

Analysis of the Effects of Maternal Body Mass Index and Gestational Weight Gain on Maternal and Neonatal Outcomes in Twin Pregnancy

Objective:To investigate the effects of maternal body mass index(BMI)and gestational weight gain on maternal and neonatal outcomes in twin pregnancies.Methods:Five hundred cases of twin pregnancies were divided into a low body weight group(68 cases),a normal weight group(355 cases),an overweight group(65 cases),and an obesity group(12 cases)according to the World Health Organization(WHO)Body Mass Index(BMI)classification guidelines Results:Comparison of weight gain during different pregnancies revealed that pregnant women were mainly of low weight and average weight.The higher the BMI before pregnancy,the higher the incidence of excessive weight gain during pregnancy.The incidences of gestational diabetes mellitus(GDM)and premature rupture of membranes in women with low weight gain were significantly higher than those in women with average weight gain and high weight gain(P<0.05).The incidences of gestational hypertension,preeclampsia,and anemia in women with high weight gain were significantly higher than those in women with low weight gain and average weight gain(P<0.05).The incidence of neonatal birth weight,fetal distress,and macrosomia in the high weight gain group was significantly higher than those in the low weight gain and average weight gain groups(P<0.05).The birth weight of newborns in low-weight gain mothers was significantly lower than that of normal-weight gain mothers(P<0.05).Conclusion:Poor maternal and infant outcomes were common in women with insufficient or excessive weight gain during pregnancy.Therefore,for women with twin pregnancies,weight management is crucial to ensure maternal and infant health.

Adverse pregnancy outcomes in women with high pre-pregnancy body mass index

Background/Aims: Obesity along with high prepregnancy body mass index (PP-BMI) is known to cause many adverse pregnancy outcomes. In Thailand, there is not much study showing both the prevalence and complications of these conditions. The objectives of this study were to estimate the prevalence of prepregnancy overweight and obesity and their impacts on adverse pregnancy outcomes. Methods: This study was a cross sectional study. Data were collected retrospectively from hospital electronic database along with manual retrieval from medical charts and labor records. Data of all delivery women from 1st February 2011 to 31st August 2012 were collected. When excluded cases with incomplete data and those without PP-BMI, 5420 cases were into analysis. Descriptive and inferential data analyses were used with both univariate and multivariate methods. Results: The proportion of pregnant women with overweight and obesity were 11.1% and 3.9%. After multiple logistic regression analysis was done, women in obesity group were correlated with having 1, 2 and 3 complications. They were also correlated with preeclampsia, gestational diabetes, cesarean section, higher birth weight group and long neonatal length. Conclusions: This Thai prevalence of obesity in pregnancyshould alarm health care providers to be more prepared, for a future health problem of the country. Many complications that come with obese pregnant women that were reported in western countries also happen in Thai population. Decreasing body weight before conception, giving correct health education, well planned pregnancy;antenatal lifestyle intervention and even gestational weight gain restricttion could help avoiding these uneventful morbidities.

High pre-delivery body mass index also caused adverse pregnancy outcomes

Background/Aims: It is known that high pre-preg-nancybody mass index (BMI) and high gestational weight gain both can cause many adverse pregnancy outcomes. High pre-delivery BMI (PD-BMI), though theoretically could do similar effects, is rarely been studied. The objectives of this study were to show the distribution of PD-BMI of the delivery women and to identify its correlation with adverse pregnancy outcomes. Methods: This study was a cross sectional study. Data were collected retrospectively from hospital electronic database of Lampang Regional Hospital (LPH) along with manual retrieval from medical charts and labor records. Data of all pregnant women who delivered at labor room were collected from 1st February 2011 to 31st August 2012. After preterm and multifetal pregnancies were excluded, 4999 cases were into the analysis. Descriptive and inferential data analyses were used with both univariate and multivariate methods. Results: In this group of women, 93.9% were in the PD-BMI range of 20.0 -34.9 kg/m2. After multivariate analysis was used, higher PD-BMI was shown to be correlated with higher cesarean section, neonates weighing ≥3500 gmand long neonatal length with relative risk (RR) and 95% confidence interval (95% CI) of 1.11 (1.09 - 1.13), 1.15 (1.12 - 1.17) and 1.07 (1.05 - 1.09), respectively. Conclusions: High PD-BMI was correlated with multiple adverse pregnancy outcomes. Interestingly, their effect sizes were much smaller comparing to high pre-pregnancy BMI and high gestational weight gain. It confirmed the current recommendations to monitor pre-pregnancy BMI and gestational weight gain to avoid unwanted morbidities.

Analysis on Family History of Diabetes, Weight Gain during Pregnancy and Pre-pregnancy Body Mass Index on 82 Pregnant Women with Gestational Diabetes Mellitus

Objective:To investigate the effects of family history of diabetes mellitus,Gestational Weight Gain(GWG)and Body Mass Index(BMI)before pregnancy on Gestational Diabetes Mellitus(GDM).Method:82 pregnant women with GDM who were hospitalized and delivered in the obstetrics department of our hospital from September 2017 to September 2019 were selected as the observation group,and 60 pregnant women with normal glucose tolerance test in the same period were selected as the control group;The relationship between family history of diabetes,weight gain during pregnancy and pre-pregnancy Body Mass Index and GDM were analyzed.Results:The age,pre-pregnancy weight and weight gain during pregnancy were significantly higher in the observation group than in the control group(P<0.05),and the family history of diabetes and pre-pregnancy Body Mass Index were higher in the observation group than in the control group(P<0.05),and the differences were statistically significant.Conclusion:It is suggested that family history of diabetes is related to gestational diabetes mellitus.Excessive GWG growth during pregnancy and high Body Mass Index before pregnancy may increase the risk of gestational diabetes mellitus in pregnant women.

Association of gestational anemia with pregnancy conditions and outcomes: A nested case-control study

BACKGROUND Gestational anemia is a serious public health problem that affects pregnant women worldwide.Pregnancy conditions and outcomes might be associated with the presence of gestational anemia.This study investigated the association of pregnancy characteristics with anemia,exploring the potential etiology of the disease.AIM To assess the association of pregnancy parameters with gestational anemia.METHODS A nested case-control study was conducted based on the Chinese Pregnant Women Cohort Study-Peking Union Medical College Project(CPWCS-PUMC).A total of 3172 women were included.Patient characteristics and gestational anemia occurrence were extracted,and univariable and multivariable logistic regression models were used to analyze the association of pregnancy parameters with gestational anemia.RESULTS Among the 3172 women,14.0% were anemic,46.4% were 25-30 years of age,21.9%resided in eastern,15.7%in middle,12.4%in western 18.0% in southern and 32.0%in northern regions of China.Most women(65.0%)had a normal prepregnancy body mass index.Multivariable analysis found that the occurrence of gestational anemia was lower in the middle and western regions than that in the eastern region[odds ratio(OR)=0.406,95%confidence interval(CI):0.309-0.533,P<0.001],higher in the northern than in the southern region(OR=7.169,95% CI:5.139-10.003,P<0.001),lower in full-term than in premature births(OR=0.491,95% CI:0.316-0.763,P=0.002),and higher in cases with premature membrane rupture(OR=1.404,95% CI:1.051-1.876,P=0.02).CONCLUSION Gestational anemia continues to be a health problem in China,and geographical factors may contribute to the situation.Premature birth and premature membrane rupture may be associated with gestational anemia.Therefore,we should vigorously promote local policy reformation to adapt to the demographic characteristics of at-risk pregnant women,which would potentially reduce the occurrence of gestational anemia.

Cervicovaginal Inflammatory Cytokines, Obesity and Inter-Pregnancy Interval Negatively Affect Pregnancy Duration in Pregnant Women at High-Risk for Recurrent Spontaneous Preterm Birth

Objectives: Evaluation of change of cervicovaginal fluid (CVF) cytokines’ levels during pregnancy and its relation to incidence of preterm birth (PTB). Patients & Methods: Pregnant women with history of PTB and cervical length α (TNF-α) and interleukins (IL)-6 and -10 levels. Study outcomes included differences in cytokines’ levels between samples and groups. Results: Sample-I cytokines’ levels were significantly higher in study than control women. Cytokines’ levels in Sample-II were significantly higher in control, while were significantly lower in study women compared to Sample-I. Sixteen study women had PTB and had significantly higher CVF levels of IL-10 and TNF-α estimated in both samples than women had no PTB. Pregnancy duration was negatively correlated with maternal body mass index (BMI) and cytokines’ levels, while was positively correlated with inter-pregnancy interval (IPI). Cytokines’ levels were positively correlated with BMI and negatively correlated with IPI. Short IPI and high TNF-α levels are negative predictors for pregnancy duration. Conclusion: High BMI, short IPI and high CVF inflammatory cytokines’ levels negatively affect pregnancy duration especially in women with history of recurrent PTB. Early prophylactic CC for women at high-risk of SPTB can modulate local immune disturbance, reduce incidence of SPTB and prolong pregnancy duration.

Health behavior after intrahepatic cholestasis of pregnancy

Background: Pregnancy is an opportunity to adopt favorable health behaviors. We studied whether intrahepatic cholestasis of pregnancy (ICP) promotes favorable health behavior in later life. Design: A prospective controlled cohort study. The method was a questionnaire survey in 2010 among 575 women with ICP and 1374 controls, all having delivered between the years 1969 and 1988 in Tampere University Hospital in Finland. Questionnaires were sent to 544 ICP patients and 1235 controls. Responses were received from 1178 (response rate 66.2%). The main outcome measures concerning recent or current health behavior were smoking, alcohol consumption, physical activity, body mass index (BMI) and special diet. Results: Current smoking was less common in the ICP group than among controls (10.5% vs 15.7%, p = 0.017). Assessed by smoking pack years there was a similar difference: in the ICP group 11.7% of women had at least 10 smoking pack years compared to 18.0% of the controls (p = 0.006). Recent alcohol consumption did not separate the two groups. The groups did not differ as to reported physical activity assessed in MET units. Fewer ICP women had had BMIs of 30 or more during pregnancy compared with controls (18.8% vs 25.1%, p = 0.023). In other points of life the BMI differences were not statistically significant. Weight-loss diet and gallbladder diet were more common in the ICP group (6.3% vs 3.6%, p = 0.044, and 3.0% vs 1.3%, p = 0.038). Conclusions: Having developed ICP two to four decades earlier seemed to constitute an effective intervention for smoking habits but not for other aspects of health behavior.

目的:探讨孕前不同体质量指数(BMI)及孕期体重不同增加量(GWG)与子痫前期(PE)产妇妊娠结局的关系。方法:选取160例收治的PE产妇作为PE组;同期60例健康体检孕妇作为对照组。PE组产妇再根据病情分为轻度组(MPE组,n=65)和重度组(SPE组,n=95);根据BMI分为超重肥胖组(n=15)、正常体重组(n=107)及低体重组(n=38);根据GWG分为增长过多组(EGWG组,n=91)、增长适宜组(AGWG组,n=47)及增长过少组(IGWG组,n=22)。比较PE组与对照组及不同病情PE组一般资料、孕前BMI、孕期GWG,分析孕前BMI、孕期GWG与PE产妇妊娠结局的关系。结果:PE组和对照组年龄、孕前BMI、孕期GWG、妊娠期糖尿病、高血压家族史有统计学差异(P<0.05);不同病情PE组患者孕前BMI、孕期GWG、妊娠期糖尿病、高血压家族史差异有统计学意义(P<0.05)。超重肥胖组和低体重组不良妊娠结局的总发生率高于正常体重组(P<0.05)。妊娠EGWG组和IGWG组不良妊娠结局的总发生率高于妊娠AGWG组(P<0.05)。相关性分析显示,孕前BMI、孕期GWG与PE妊娠结局均呈正相关关系(P<0.05)。结论:孕前BMI、孕期GWG与PE发生密切相关,且孕前超重肥胖、低体重、EGWG、IGWG均与PE患者不良妊娠结局密切相关。

双胎妊娠增重适宜范围与母婴围产期结局的关系

目的 探讨双胎妊娠孕妇孕中、晚期适宜的孕期体重增长(gestational weight gain,GWG)范围,并进一步分析GWG范围与母婴围产期妊娠结局的关系。方法 选取2012年1月—2022年12月于广东省佛山市妇幼保健院建档产检并分娩的2 222例双胎妊娠孕妇为研究对象,根据体质指数(body mass index,BMI)将孕妇分为低体重组、正常体重组、超重组及肥胖组。根据围产期结局确定低风险人群,采用四分位数法计算该人群孕中、晚期每周增重的适宜范围,并将双胎妊娠孕妇增重情况分为增重不足、增重适宜和增重过多。采用多因素logistic回归模型分别分析增重情况与6种围产期结局的关系,对新生儿结局采用广义估计方程进行分析。结果 不同BMI组别间初产妇占比、绒毛膜性、受孕方式的比较差异均有统计学意义(均P <0.05)。对于围产期结局,不同BMI组别间妊娠期糖尿病、妊娠期高血压和大于胎龄儿的比较差异均有统计学意义(均P<0.05)。根据819例低风险孕妇计算得出低体重组、正常体重组、超重组和肥胖组每周体重增长适宜范围分别为0.579~0.808 kg、0.531~0.769 kg、0.479~0.711 kg和0.430~0.679 kg。多因素logistic回归模型提示,GWG不足会增加早产(OR=1.36,95%CI:1.11~1.67)、小于胎龄儿(OR=1.74,95%CI:1.34~2.27)的发生风险,而GWG过多则会增加子痫前期(OR=1.82,95%CI:1.30~2.54)、妊娠期高血压(OR=1.72,95%CI:1.04~2.86)和大于胎龄儿(OR=2.17,95%CI:1.52~3.11)的发生风险。结论 基于低风险人群孕中、晚期GWG的适宜范围,双胎妊娠孕妇GWG增重过多或过少都会增加不良妊娠结局的风险,加强对双胎妊娠孕妇的体重管理有助于促进双胎妊娠孕妇母婴围产期健康。

BMI变化对妊娠期糖尿病母婴结局的影响

目的探讨妊娠期糖尿病(GDM)孕妇孕期不同体重指数(BMI)变化与母婴结局的相关性。方法选取百色市人民医院2019至2021年进行产检、分娩并确诊为GDM的孕妇200例作为研究对象,根据体重(BMI)增长幅度(ΔBMI)变化量将其分成ΔBMI<4 kg/m^(2)组(BMI增长不足组,n=51)、4 kg/m^(2)≤ΔBMI≤6 kg/m^(2)组(BMI增长正常组;n=87)和ΔBMI>6 kg/m^(2)组(BMI增长过多组,n=62)。利用调查问卷发放的方式获取所有受试者的基线资料与实验数据,利用Logistic回归模型分析评估不同BMI变化与母婴结局的相关性。结果BMI增长过多组妊高症、先兆子痫、产后出血各占29.03%、18.03%、41.94%,BMI增长正常组各占19.54%、14.94%、12.64%,BMI增长不足组各占25.49%、7.84%、13.73%。②BMI增长过多组胎儿窘迫、巨大儿各占29.03%、40.32%,BMI增长正常组各占13.79%、14.94%,BMI增长不足组各占9.80%、7.84%。BMI增长过多组产后并发症发生率、新生儿结局不良率较BMI增长正常组、BMI增长不足组更高(P<0.05)。将BMI增长正常作为参照进行Logistic回归分析发现,BMI增长不足会增加妊高症、先兆子痫、产后出血、胎儿窘迫、巨大儿的发生风险(OR=3.376、2.658、1.354、1.713、2.165,P<0.05);BMI增长过多会增加妊高症、先兆子痫、产后出血、胎儿窘迫、巨大儿、低体重儿和GDM的发生风险(OR=2.647、1.659、3.675、4.132、2.876、3.151、3.325)。结论GDM产妇的BMI增长不足、BMI增长过多均会增加母婴结局的不良发生率,故在孕期内控制可监测孕妇的体重增长,不仅有利于母婴的健康,对降低GDM及相关并发症发生率也有积极的影响。

妊娠期糖尿病孕妇孕前正常体重指数与妊娠结局的相关性

目的:探讨正常孕前体重指数(body mass index,BMI)的妊娠期糖尿病(gestational diabetes mellitus,GDM)孕妇不同BMI范围对妊娠结局的影响。方法:回顾性收集南京市妇幼保健院2022年5月—2023年5月孕前正常BMI的GDM孕妇2319例,按照孕前BMI分为A组(18.5 kg/m^(2)≤BMI<20.0 kg/m^(2),581例)、B组(20.0 kg/m^(2)≤BMI<22.0 kg/m^(2),922例)与C组(22.0 kg/m^(2)≤BMI<24.0 kg/m^(2),816例)。拟合Logistic回归模型,对不同孕前BMI与妊娠结局的相关性进行分析评价。结果:3组GDM患者发生GDM A2级、子痫前期、巨大儿和新生儿高胆红素血症的风险随孕前BMI的升高而增加;发生胎盘早剥、新生儿低血糖症的风险随孕前BMI的升高而降低。在正常BMI人群中,GDM女性孕前较高或较低的BMI水平是发生GDM A2级、子痫前期、巨大儿、新生儿高胆红素血症、胎盘早剥和新生儿低血糖症的独立危险因素。结论:早期体重管理可能是预防GDM孕妇不良妊娠结局发生的不容忽视的关键措施之一。

孕早期妊娠相关血浆蛋白A等多指标联合预测妊娠期糖尿病的价值

目的:调查孕妇孕前体质量分布情况,分析孕前体质量指数(BMI)与妊娠期高血压疾病的相关性。方法:收集2 618例单胎孕妇的临床资料,根据孕前BMI分为低体质量组234例、正常体质量组1 610例、超重组545例、Ⅰ度肥胖组128例、Ⅱ度肥胖组101例。比较5组孕妇的一般资料和孕产情况,并分析孕前BMI与妊娠期高血压疾病的相关性。结果:5组孕妇年龄、身高、孕次及产次等比较差异均无统计学意义(P>0.05);5组孕妇分娩时间、分娩方式比较差异有统计学意义(P<0.05);妊娠期高血压疾病的发病率随孕前BMI升高而升高(P<0.05);孕前超重、Ⅰ度肥胖及Ⅱ度肥胖孕妇妊娠期高血压疾病的发病风险增高(P<0.05),Ⅱ度肥胖组孕妇发生妊娠期高血压、子痫前期、重度子痫前期的风险高于其他组,分别是正常体质量孕妇的5.19、8.77、7.97倍。孕前超重及肥胖的相对危险度>1,95%CI:不包括1,孕前BMI≥24 kg/m2是妊娠期高血压疾病的危险因素。结论:孕前超重和肥胖是妊娠期高血压疾病的危险因素,应加强对育龄期妇女尤其是超重和肥胖女性孕前及孕期的体质量管理。

炔雌醇环丙孕酮片联合二甲双胍治疗肥胖型PCOS有效性的随机对照研究

目的:探究二甲双胍治疗肥胖型多囊卵巢综合征(PCOS)效果及对患者性激素、妊娠率及妊娠期并发症的影响。方法:采用随机对照研究方法,纳入2021年7月-2023年1月本院收治的PCOS患者210例,随机数字法分为对照组(n=102,炔雌醇环丙孕酮片治疗)和观察组(n=108,炔雌醇环丙孕酮片联合二甲双胍治疗)。比较两组治疗前后一般情况指标[体重、体质指数(BMI)、腰臀比(WHR)]、糖代谢指标[空腹血糖(FPG)、空腹胰岛素(FINS)、胰岛素抵抗指数HOMA-IR]、脂代谢指标[总胆固醇(TC)、载脂蛋白A(ApoA)、高密度脂蛋白(HDL-C)、低密度脂蛋白(LDL-C)]、性激素指标[促黄体生成素(LH)、卵泡刺激素(FSH)、睾酮(T)、雌二醇(E_(2))];随访9个月,统计妊娠率及统计妊娠期并发症。结果:治疗后,两组体重、BMI、WHR均下降且观察组(63.0±8.7 kg、26.1±2.9 kg/m^(2)、0.73±0.15)低于对照组(66.4±9.7 kg、27.6±3.5 kg/m^(2)、0.82±0.19),观察组FPG(4.01±0.96 mmol/L)、FINS(18.69±2.94 mU/L)、HOMA-IR(3.30±0.88)水平均低于对照组(4.96±1.10 mmol/L、22.37±3.82 mU/L、4.93±1.10),两组TC、HDL-C、LDL-C水平均下降且观察组低于对照组,两组ApoA水平均上升且观察组高于对照组,两组LH、T、E_(2)水平均下降,两组FSH水平均上升,且观察组指标水平变化幅度大于对照组(均P<0.05)。结论:二甲双胍治疗PCOS疗效提高,利于提升患者糖、脂代谢能力,改善患者内分泌功能,纠正代谢紊乱,从而提高妊娠率,且妊娠期并发症发生风险降低。

妊娠女性孕前体质量指数与肾功能及妊娠结局的关系

目的分析单胎孕妇孕前体质量指数(BMI)、分娩前肾功能相关指标及妊娠结局,探讨孕前BMI对肾功能及妊娠结局的影响。方法回顾性分析1218例常规围生保健及分娩的单胎孕妇资料,并按孕前BMI不同分为体重过轻组(<18.5 kg/m^(2),176例)、体重正常组(18.5~24.9 kg/m^(2),670例)、超重组(25.0~27.9 kg/m^(2),266例)、肥胖组(≥28.0 kg/m^(2),106例)。其中重度子痫前期孕妇806例,以34周为界,分为早发型组(442例)和晚发型组(364例)。对各组孕妇的肾功能相关指标及妊娠结局进行比较。结果早发型组的孕前BMI(23.32±4.30)kg/m^(2)高于晚发型组的(22.44±3.74)kg/m^(2),差异有统计学意义(P<0.05)。体重正常组和体重过轻组肾功能指标比较,差异均无统计学意义(P>0.05);体重正常组肾功能指标均低于超重组及肥胖组,差异均有统计学意义(P<0.05);超重组尿酸、β2微球蛋白、α1微球蛋白低于肥胖组,差异均有统计学意义(P<0.05)。各组间发病孕周、分娩孕周比较,差异均无统计学意义(P>0.05);体重正常组新生儿体重和1 min Apgar评分均高于体重过轻组、超重组及肥胖组,差异均有统计学意义(P<0.05)。结论孕前BMI对单胎孕妇肾功能和妊娠结局有一定的影响。控制孕前BMI在正常范围有助于维持正常肾功能并改善妊娠结局。
