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.

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.

Relationship between gestational body mass index,blood pressure variability,and postpartum depression in pregnant women with preeclampsia

BACKGROUND Pre-eclampsia has long been proven to be an independent risk factor for postpartum depression(PPD).Excessive increase in body mass index(BMI)during pregnancy is an important factor inducing pre-eclampsia.Increased blood pressure is the main symptom of patients with pre-eclampsia.However,whether there is a correlation between BMI and blood pressure variability during pregnancy and PPD occurrence in pregnant women with pre-eclampsia remains unclear.AIM To investigate the relationship between BMI,blood pressure variability,and PPD in pregnant women with pre-eclampsia.METHODS Using a cross-sectional survey research,201 pregnant women with pre-eclampsia who were treated and delivered in Suzhou Ninth People’s Hospital from May 2016 to June 2024 were selected as this study’s subjects.At 42 days after delivery,the subjects were re-examined in the hospital’s outpatient department.The Edinburgh Postnatal Depression Scale(EPDS)was used to evaluate whether PPD symptoms,divided the subjects into two groups:The PPD and non-PPD groups.We analyzed clinical data,changes in BMI during pregnancy,and blood pressure variability in the two groups.The Pearson method was used to test the correlation between BMI increase,blood pressure variability during pregnancy,and EPDS score in patients with pre-eclampsia.Logistic regression analysis was performed to explore whether increased BMI and blood pressure variability during pregnancy are influencing factors for PPD occurrence in patients with pre-eclampsia.RESULTS Of the 201 pre-eclamptic women who underwent an outpatient review 42 days after delivery,37 had PPD symptoms based on the EPDS scale evaluation,resulting in an incidence rate of 18.41%(37/201).The differences between the PPD and non-PPD groups in terms of age,educational level,place of residence,reproductive history,gestational age,mode of delivery,newborn gender,and newborn birth weight were not statistically significant(P>0.05).The gestational BMI increase,24-hour systolic blood pressure(SBP)variability,and 24-hour diastolic blood pressure(DBP)variability in the PPD group were significantly higher than those in the non-PPD group;the differences were statistically significant(P<0.001).Pearson correlation analysis showed that BMI increase,SBP variability,and DBP variability during pregnancy correlated positively with the EPDS score of pregnant women with pre-eclampsia(r=0.349,0.336,and 0.241;P<0.001).Logistic regression analysis showed that a high increase in BMI during pregnancy[odds ratio(OR)=4.614,95%confidence interval(CI):1.749-12.170,P=0.002],large variability in 24-hour SBP(OR=2.910,95%CI:1.322-6.404,P=0.008),and large variability in 24-hour DBP(OR=2.347,95%CI:1.138-4.831,P=0.021)were factors affecting PPD occurrence in patients with pre-eclampsia.CONCLUSION Increased BMI and blood pressure variability during pregnancy can increase the risk of PPD in patients with preeclampsia.Strengthening pregnancy guidance and controlling fluctuations in BMI and blood pressure variability during pregnancy within a reasonable range can help reduce the risk of PPD in patients with pre-eclampsia.

Secular Changes on the Distribution of Body Mass Index among Chinese Children and Adolescents, 1985-2010

Objective To analyze the change in Body Mass Index （BMI） distribution among Chinese children and adolescents for the development of more effective intervention for childhood obesity. Methods Data on the national students＇ constitution and health survey between 1985 and 2010 was used for this study. Subjects were students aged 7-18 randomly selected from 30 provinces in China. BMI for-age curves were developed by LMS method, and the trend of BMI distribution was determined by comparing the upper BMI percentiles and analyzing the skew shift of distribution between 2985 and 2010. Results An overall positive swift trend of BMI between 1985 and 2010 was observed among the Chinese school-age children and adolescents. The average median of the BMI increased from 16.8 and 17.0 ks/m2 to 18.2 and 17.9 kg/m2 in 25 years, with increments 0.56 and 0.36 kg/m2 per decade for males and females, respectively. The more obvious increments were found at the high BMI. The total increments of BMI in this period were 4.03 and 2.20 kg/m2 at the 85th, 6.24 and 3.57 kg/m2 at the 95th, and 6.99 and 4.27 kg/m2 at the 97th percentiles, for males and females, respectively. Conclusion Obvious increments were observed at high BMI of the Chinese children and adolescents. More effective interventions should be taken for control and prevention of obesity and its health consequence for these subgroups. It is necessary to establish a risk-complex system consisting of the identification of BMI scope, the screen of the disease risk factors and the assessment of excessive adiposity.

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.

Prognostic value of preoperative weight loss-adjusted body mass index on survival after esophagectomy for esophageal squamous cell carcinoma

BACKGROUND The impact of body mass index(BMI)on survival in patients with esophageal squamous cell carcinoma(ESCC)undergoing surgery remains unclear.Therefore,a definition of clinically significant BMI in patients with ESCC is needed.AIM To explore the impact of preoperative weight loss(PWL)-adjusted BMI on overall survival(OS)in patients undergoing surgery for ESCC.METHODS This retrospective study consisted of 1545 patients who underwent curative resection for ESCC at West China Hospital of Sichuan University between August 2005 and December 2011.The relationship between PWL-adjusted BMI and OS was examined,and a multivariate analysis was performed and adjusted for age,sex,TNM stage and adjuvant therapy.RESULTS Trends of poor survival were observed for patients with increasing PWL and decreasing BMI.Patients with BMI≥20.0 kg/m2 and PWL<8.8%were classified into Group 1 with the longest median OS(45.3 mo).Patients with BMI<20.0 kg/m2 and PWL<8.8%were classified into Group 2 with a median OS of 29.5 mo.Patients with BMI≥20.0 kg/m2 and PWL≥8.8%(HR=1.9,95%CI:1.5-2.5),were combined into Group 3 with a median OS of 20.1 mo.Patients in the three groups were associated with significantly different OS(P<0.05).In multivariate analysis,PWL-adjusted BMI,TNM stage and adjuvant therapy were identified as independent prognostic factors.CONCLUSION PWL-adjusted BMI has an independent prognostic impact on OS in patients with ESCC undergoing surgery.BMI might be an indicator for patients with PWL<8.8%rather than≥8.8%.

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.

Attitudes towards, and methods of, maintaining or losing body weight among adults

To investigate motivators and strategies of adult weight loss or management, 1805 adults aged 18 - 65 were asked by computer assisted telephone interviews about their weight management behavior during the previous four weeks. High levels of importance to reduce risks associated with chronic diseases such as cancer, heart disease and diabetes were observed, although were indistinguishable between people attempting or not attempting to lose or maintain weight. Results showed that BMI was the strongest predictor of attempting to manage weight irrespective of age and, compared with males, females were more likely to attempt weight management at a lower BMI. Among the weight management group, the most popular weight management strategy was to choose healthier food options (77% and 70% for females and males respectively). With the weight management group also more likely to be monitoring the amount of food they consume, limiting portions sizes and tracking their physical activity participation compared with people not managing their weight. The current study showed that the likelihood of weight management within four weeks prior to the survey peaked for both sexes when BMI reached obese levels, (BMI = 30 - 39.9), suggesting that among people categorised as obese most were attempting to manage their weight. The results also suggest that at least some adults were not attempting to maintain their weight in the four weeks prior to the survey, irrespective of their BMI status. The implications of these findings suggest more effective approaches to weight loss and maintenance could focus on strategies that directly address the benefits and motivations of weight loss and weight maintenance, rather than focusing on conveying the risks of being overweight and the importance of avoiding chronic disease.

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.

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.

孕前体质指数与妊娠糖尿病及孕期血清Ghrelin nesfatin-1表达的关系

目的探讨孕前体质指数(BMI)与妊娠糖尿病(GDM)发生及血清生长激素释放肽(Ghrelin)、摄食抑制因子(nesfatin-1)表达的关系。方法选取2019年6月至2020年12月榆林市榆阳区妇幼保健院和延安市安塞区人民医院收治的150例GDM孕妇作为GDM组,选择同期健康孕妇150例作为对照组。收集两组孕妇孕前BMI,检测孕期血清Ghrelin、nesfatin-1水平,采用Pearson法分析与孕前BMI的相关性,采用logistic回归分析法分析GDM发生的影响因素。结果对照组孕妇孕前BMI、孕期Ghrelin、nesfatin-1水平分别为(22.73±3.17)kg/m^(2)、(1.36±0.42)mmol/L和(2.51±0.78)mmol/L,GDM组孕前BMI、孕期Ghrelin、nesfatin-1水平分别为(25.26±2.85)kg/m^(2)、(1.14±0.34)mmol/L和(2.86±0.89)mmol/L,两组比较差异均有统计学意义(P<0.05);GDM孕妇孕前BMI与孕期血清Ghrelin水平呈负相关(r=-0.488,P<0.05),与孕期nesfatin-1水平呈正相关(r=0.428,P<0.05);孕前BMI、孕期血清Ghrelin、nesfatin-1均为GDM发生的影响因素(P<0.05)。结论孕前BMI对孕期血清Ghrelin、nesfatin-1表达均有影响,三者均为GDM发生的影响因素。

Obesity in Relation to Ovarian Response in IVF Treatment

Introduction: The effect of Body Mass Index (BMI), which reflects the woman’s obesity, in IVF treatment cycle, remains unclear. In 1997, the World Health Organization (WHO) provided authoritative refinements to the over-weight terminology and BMI cutoffs [1]. Objective: To verify the relationship between BMI and ovarian response in IVF treatment cycle. Design: Retrospective study. Materials & Methods: The study includes 2625 IVF treatment cycles performed in our IVF center in the period of 4 years. Patients were divided into five groups using the WHO criteria according to their BMI [2]. Cancellation rate, mean last E2 before hCG administration, mean endometrial thickness, mean duration of stimulation, number of eggs retrieved, fertilization rate, pregnancy and abortion rates were analyzed. The unpaired t-test was used in statistical analysis. Results: There was statistically significant less mean oestradiol level prior to hCG, less endometrial thickness and less number of simulation days as BMI gets higher. In contrast, there was a positive relationship between cancellation rate and higher BMI except with BMI >39 which was not, possibly due to lower number of patients available. But if we look at the cause of cancellation, it was 100% due to insufficient number of follicles obtained for this group (BMI >39). Also, days of stimulation are significantly lower for the same group of patients in comparison with the other groups. Retrieval, fertilization and pregnancy rates were not significant between all groups. Abortion rate gets significantly higher as BMI increased. Conclusion: Overweight affects ovulation, if we consider the cause of cancellation being insufficient number of follicles reflects the poor response. The fertilization and pregnancy rate were not affected once oocytes retrieved. The reduction of weight is an important part of infertility treatment in obese women with regards to the ovarian response and abortion rate in IVF cycle.

A Modified Ultra-Long Downregulation Protocol Improves Pregnancy Outcomes in High Body Mass Index Patients Undergoing In vitro Fertilization/Intracytoplasmic Sperm Injection Treatment

Objective:Overweight and obesity are increasingly epidemic and negatively related to reproductive outcome.The aim of this study was to investigate the advantages of a modified ultra-long downregulation protocol on pregnancy outcomes of patients with high body mass index(BMI)undergoingin vitro fertilization(IVF)/intracytoplasmic sperm injection(ICSI),compared to the long protocol(LP).Methods:We retrospectively analyzed the clinical data of 3,920 infertile patients at the Reproductive and Genetic Hospital of Citic-Xiangya from January 2012 to December 2017 by propensity score matching(PSM).Patients were divided into two groups:modified ultra-LP(MULP)(n=1,960)and LP(n=1,960).Results:In the MULP group,live birth rate(52.65%vs.46.79%,P<0.001,odds ratio[OR]:1.784,95%confidence interval[CI]:1.563-2.036),clinical pregnancy rate(62.50%vs.57.91%,P=0.003,OR:1.211,95%CI:1.066-1.377),and implantation rate(53.24%vs.49.65%,P=0.004,OR:1.155,95%CI:1.048-1.272)were statistically significantly higher than those of the LP group.Moreover,the cycle cancellation rates(12.70%vs.15.15%,P=0.027,OR:0.815,95%CI:0.68-0.977),abortion rates(12%vs.14.8%,P=0.046,OR:0.785,95%CI:0.619-0.996),and ectopic pregnancy rates(1.06%vs.2.11%,P=0.04,OR:0.497,95%CI:0.252-0.98)were lower than those in the LP group.Conclusion:The modified ultra-long downregulation protocol improved the pregnancy outcomes in patients with high BMI undergoing IVF/ICSI treatment,providing a potential option for physicians when deciding an optimized ovary stimulation protocol for high BMI patients.

Upshots of health education among patients with type 2 diabetes mellitus: A field study in Mysuru

Objective:This study was conducted to assess the impact of health education on lifestyle modification and disease status of diabetic patients for 6 months in rural Mysuru in Southern India.Materials and Methods:A quasi-experimental study was conducted among 104 patients with type 2 diabetes mellitus in rural Mysuru,India from July to December 2022.Participants were assigned to two groups:intervention(n=52)and control(n=52),and their data were collected.The intervention group was educated about the disease and its management and was given printed pamphlets containing information to be followed,whereas the participants in the control group were asked to continue their routine health checkups.The body mass index(BMI),weight,fasting blood sugar(FBS),knowledge about the disease,and behavior changes were recorded and compared between the two groups before and after 6 months.Results:The mean FBS value,BMI and weight decreased significantly in the intervention group after 6 months(FBS:164.79±47.59 mg/dL vs.141.92±25.63 mg/dL,P<0.001;BMI:22.97±3.75 kg/m2 vs.22.62±3.29 kg/m2,P<0.05;weight:62.82±11.92 kg vs.61.54±10.67 kg,P<0.05).The posttest period also showed an improvement in physical activity,diet,and medication adherence in the intervention group compared to the control group(P<0.05).The knowledge scores also improved postintervention which was statistically significant with the Wilcoxon signed-rank test(P<0.05).Conclusions:The effectiveness of the educational intervention was also supported by lower FBS levels and decrease in BMI and weight compared to before.The findings of this study may help and make it easier to plan studies on people with diabetes mellitus in various settings.

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。

两次妊娠间体重变化对妊娠期糖尿病再发的影响分析

目的探讨连续两次妊娠间体重变化与妊娠期糖尿病(gestational diabetes mellitus,GDM)再发之间的关联。方法基于广东省妇幼保健院信息系统,选取2017年1月~2022年7月有2次分娩记录且第1次妊娠患有GDM的女性为研究对象。两次妊娠间体重变化定义为第2次妊娠孕前体质量指数(body mass index,BMI)减去前1次妊娠孕前BMI,并将其分为4组(<-1、-1~、1~、≥3 kg/m^(2)),将-1~kg/m^(2)组(体重稳定组)作为参照。采用Logistic回归模型分析连续两次妊娠间体重变化与GDM再发及两次妊娠糖耐量试验血糖值变化的关联。结果在703名研究对象中,有326人(46.4%)再次发生了GDM。与妊娠间BMI变化-1~kg/m^(2)组相比,BMI变化1~kg/m^(2)和≥3 kg/m^(2)组再发GDM的风险增加,比值比(odds ratio,OR)[95%置信区间(confidence interval,CI)]分别为2.16(1.52~3.08)和2.56(1.44~4.56),GDM再发风险随着妊娠间BMI增加而增加(P-trend<0.01)。然而BMI变化<-1 kg/m^(2)组与GDM再发无显著关联,OR(95%CI)为0.95(0.57~1.57)。妊娠间BMI每增加1 kg/m^(2),空腹血糖升高、服糖后1 h血糖升高的风险增加,OR(95%CI)分别为1.15(1.05~1.26)和1.21(1.10~1.33)。结论有GDM史的妇女是GDM再发的高危人群,连续两次妊娠间体重增加可显著增加GDM再发的风险。该研究结果提示,应对有GDM患病史并有再次生育意愿的妇女加强健康教育,提高其对体重管理重要性的认识,减少GDM的再发生,保障母婴健康。

孕前不同体质量指数及孕期体重不同增加量与子痫前期产妇妊娠结局的关系

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。

备孕女性BMI对IVF/ICSI-ET妊娠结局的影响

目的:探讨体外受精/卵胞质内单精子注射-胚胎移植(IVF/ICSI-ET)对不同体质指数(BMI)女性患者临床结局的影响。方法:回顾性分析2020年1月-2023年3月本中心生殖中心接受IVF/ICSI-ET治疗的女性患者临床资料,根据女性BMI分为低体质量组(BMI<18.5kg/m^(2))、正常体质量组(18.5kg/m^(2)≤BMI<24.9kg/m^(2))、超重组(BMI≥24.9kg/m^(2)),比较3组行IVF/ICSI-ET助孕临床结局,logistic回归分析影响IVF/ICSI-ET临床妊娠率和活产率相关影响因素。结果:3组不孕年限、BMI、Gn用量、不孕原因存在差异(P<0.05)。低体质量组(36%,31/86)、正常体质量组(39.8%,276/693)、超重组(43.2%,108/250)临床妊娠率无差异,流产率(16.1%,5/31)、(10.1%,28/276)、(38.0%,41/108)有差异(P<0.05),活产率(30.2%,26/86)、(34.8%,241/693)、(26.4%,66/250)有差异(P<0.05)。logistic多因素回归分析显示,BMI超重和Gn用量多是影响辅助生殖后临床妊娠的因素,Gn用量多是影响辅助生殖后妊娠活产的因素(均P<0.05)。结论:备孕女性行IVF治疗前,使BMI达到或接近正常,以改善IVF/ICSI-ET助孕的妊娠结局。
