RESUMO
BACKGROUND: An inappropriate gestational weight gain (GWG) among pregnant women with overweight/obesity is a crucial health problem. Its prevalence remains high worldwide, particularly in urban areas. The prevalence and predicting factors in Thailand are lack of evidence. This study aimed to investigate prevalence rates, antenatal care (ANC) service arrangement, predictive factors, and impacts of inappropriate GWG among pregnant women with overweight/obesity in Bangkok and its surrounding metropolitan area. METHODS: This cross-sectional, retrospective study used four sets of questionnaires investigating 685 pregnant women with overweight/obesity and 51 nurse-midwives (NMs) from July to December 2019 in ten tertiary hospitals. Multinomial logistic regression identified predictive factors with a 95% confidence interval (CI). RESULT: The prevalence rates of excessive and inadequate GWG were 62.34% and 12.99%. Weight management for pregnant women with overweight/obesity are unavailable in tertiary cares. Over three-fourths of NMs have never received weight management training for this particular group. ANC service factors, i.e., GWG counseling by ANC providers, quality of general ANC service at an excellent and good level, NMs' positive attitudes toward GWG control, significantly decreased the adjusted odds ratio (AOR) of inadequate GWG by 0.03, 0.01, 0.02, 0.20, times, respectively. While maternal factors, sufficient income, and easy access to low-fat foods reduce AOR of inadequate GWG by 0.49, and 0.31 times. In contrast, adequate maternal GWG knowledge statistically increased the AOR of inadequate GWG 1.81 times. Meanwhile, easy access to low-fat foods and internal weight locus of control (WLOC) decreased the AOR of excessive GWG by 0.29 and 0.57 times. Finally, excessive GWG significantly increased the risk of primary C/S, fetal LGA, and macrosomia 1.65, 1.60, and 5.84 times, respectively, while inadequate GWG was not associated with adverse outcomes. CONCLUSION: Prevalence rates of inappropriate GWG, especially excessive GWG remained high and affected adverse outcomes. The quality of ANC service provision and appropriate GWG counseling from ANC providers are significant health service factors. Thus, NMs should receive gestational weight counseling and management training to improve women's knowledge and practice for gestational weight (GW) control.

The achievement of recommended decision-to-delivery interval (DDI) of ≤30 minutes in emergency caesarean section (CS) is relatively low in developing countries. This study was aimed to compare DDI in emergency CS before and after the implementation of a specific care process improvement protocol, called 'code blue'. A total of 300 women underwent emergency CS were included; 150 consecutive cases before (during 2015-2016) and the other 150 consecutive cases after (during 2017-2018) 'code blue' implementation. Timing of decision-to-delivery process was compared. The results showed that median DDI was significantly shorter after 'code blue' implementation (22 vs. 52.5 minutes, p<.001). DDI of ≤30 minutes was achieved in 80% of the women under 'code blue' compared to 8% before implementation (p<.001). Significant improvements were observed regardless of decision time. Pregnancy and neonatal outcomes were comparable between the two periods. The implementation of 'code blue' protocol for emergency CS results in significantly shorter DDI and other time intervals.Impact StatementWhat is already known on this subject? Achievement of recommended decision-to-delivery interval (DDI) of ≤30 minutes in emergency caesarean section is relatively low in developing countries. Various setting-specific care improvement processes have been reported to shorten DDI.What do the results of this study add? A multidisciplinary care improvement process ('code blue') that developed according to specific evidence and based on a hospital's context can significantly shorten DDI as well as other time intervals in women requiring emergency CS.What are the implications of these findings for clinical practice and/or further research? The 'code blue' protocol could be used as a model for other hospitals and health care settings to develop their own specific quality improvement process in order to shorten DDI for emergency CS. Collaboration and communication between all staff members could help in better identification of significant barriers as well as development of appropriate solutions. Further studies are also needed to determine whether the shortened DDI could improve neonatal outcomes.

A total of 1016 pregnant women attending antenatal clinic before 20 weeks of gestation during September 2018 to February 2019 were included in a cohort study with repeated cross-sectional assessments. The study was aimed to determine prevalence and characteristics of gestational diabetes mellitus (GDM) and pregnancy outcomes by early universal screening approach. GDM screening was performed during first visit and repeated during 24-28 weeks of gestation, as necessary, using a 50-g glucose challenge test followed by a 100-g oral glucose tolerance test for GDM diagnosis. Overall prevalence of GDM was 18.6%. A significantly higher prevalence of GDM was observed among high-risk than low-risk women (21.3% vs. 13.1%, p = 0.002). GDM among low-risk women contributed to 23.3% of all GDM cases. The majority of GDM (76.2%) were diagnosed before 20 weeks of gestation, with 74.5% occurring in high-risk women and 81.8% occurring in low-risk women. When initial screening tests were normal, risk of GDM diagnosed during 24-28 weeks was 6.0% (7.5% among high-risk women and 3.1% among low-risk women). Compared to those without GDM, women with GDM significantly had lower gestational weight gain (p < 0.001), higher prevalence of preeclampsia (p = 0.001), large for gestational age (LGA) (p = 0.034) and macrosomia (p = 0.004). These outcomes were more pronounced among high-risk women with GDM. Impact StatementWhat is already known on this subject? Universal GDM screening is recommended during 24-28 weeks of gestation, either by 1- or 2-step approach. Some also recommend early GDM screening among high-risk women. Prevalence of early-onset GDM varies between studies and benefits of early diagnosis and treatment are still controversial.What do the results of this study add? Early universal GDM screening identified more women with GDM and majority could be diagnosed before 20 weeks of gestation. GDM among low-risk women contributed to 23.3% of all cases. Adverse pregnancy outcomes were more common among high-risk women with GDM. This approach could be useful and can be implemented in other settings, especially those that serve high-risk population or with high GDM prevalence.What are the implications of these findings for clinical practice and/or further research? Early universal GDM screening should be considered in settings with high prevalence of GDM and high-risk women. However, benefits of early detection and treatment of GDM should be determined in more details in the future, especially in terms of cost-effectiveness and improvement in pregnancy outcomes.

This cohort study aimed to determine the association between false-positive 50-g GCT and incidence of LGA and to evaluate predictive roles of third-trimester ultrasonographic examination. A total of 200 women with false-positive 50-g GCT and 188 women without GDM risks were enrolled. Third-trimester ultrasonographic examinations were offered. Rate of LGA during third trimester and at birth were compared between groups. Factors associated with LGA and diagnostic properties of third-trimester ultrasonography were evaluated. Incidence of LGA by third-trimester ultrasound and at birth were significantly higher in women with false-positive GCT (19.0% vs. 10.6%, p = .03 and 22% vs. 13.8%; p = .04). Factors associated with LGA included multiparity (adjusted OR 2.32, p = .01), excessive weight gain (adjusted OR 2.57, p = .01) and LGA by ultrasound (adjusted OR 9.79, p < .001). Third-trimester ultrasonography had 47.1% sensitivity, 92.1% specificity and LR + and LR- of 5.96 and 0.57 in identifying LGA infants.Impact statementWhat is already known on this subject? Women with abnormal GCT but normal OGTT (false positive GCT) might have some degree of glucose intolerance so that GDM-related outcomes could develop, including LGA, macrosomia, shoulder dystocia, and caesarean delivery. Roles of ultrasonography in the prediction of LGA and macrosomia has been reported with mixed results.What do the results of this study add? The results showed that the incidence of LGA, by third-trimester ultrasound and at birth, were significantly increased in women with false-positive GCT. Multiparity, excessive weight gain and LGA by third-trimester ultrasound significantly increased the risk of LGA. Third-trimester ultrasonography had 47.1% sensitivity, 92.1% specificity and LR + and LR- of 5.96 and 0.57 in identifying LGA infants.What are the implications of these findings for clinical practice and/or further research? More intensive behavioural and dietary interventions, together with weight gain control and monitoring, may be needed in women with false-positive GCT to minimise the risk of LGA. Third trimester ultrasonographic examination might be helpful to detect and predict LGA at birth and should be included into routine clinical practice. Further studies that are more widely generalisable are needed to elucidate the relationship between false-positive GCT and adverse pregnancy outcomes and to investigate the benefits of ultrasonographic examination in the prediction of LGA and macrosomia.

This retrospective cohort study aimed to determine prevalence of GDM diagnosed before 24 weeks of gestation (early-onset GDM) and evaluate associated risk factors and compare pregnancy outcomes between different GDM status. A total of 1200 pregnant women attending antenatal clinic before 24 weeks of gestation were included. GDM screening was offered during first visit and repeat during 24-28 weeks of gestation, using 50-g GCT and 100-g OGTT. GDM was diagnosed in 110 women (13.9%) and early-onset GDM was found in 57 women (9.2%), which accounted for 65.9% of all GDM. Early-onset GDM had significant lower gestational weight gain and higher rates of preeclampsia, LGA infants, and NICU admission. Independent associated factors for early-onset GDM were age ≥30 years (aOR 4.89, 95%CI: 2.08-11.50, p < .001), and previous GDM (aOR 12.26, 95%CI: 3.86-38.93, p < .001) while DM in family was the only independent factor for late-onset GDM (aOR 2.53, 95%CI: 1.42-4.51, p = .002).IMPACT STATEMENTWhat is already known on this subject? Reported prevalence of early-onset GDM varies between studies, depending on the screening strategy and criteria used. Despite treatment, early-onset GDM has been associated with increased adverse maternal and neonatal outcomes in many previous studies. The risks associated with early-onset GDM and the evidence for benefit of early treatment are still unclear.What do the results of this study add? The results showed that early-onset GDM accounted for majority (65.9%) of all GDM. Despite treatment, early-onset GDM increased risk of preeclampsia, LGA infants, and NICU admission. Independent associated factors for early-onset GDM were age ≥30 years, and previous GDM while DM in family was the only independent factor for late-onset GDM.What are the implications of these findings for clinical practice and/or further research? Early GDM screening and intensive management, especially in high-risk women, should be implemented to minimise the risks of adverse outcomes. Further studies are needed to determine appropriate criteria to define early-onset GDM and to identify women at higher risk in different population and settings with different screening strategies. Effective management and approaches for this subgroup of GDM should also be further investigated.

The study aimed to compare the incidence of large for gestational age (LGA) infants between women with a false positive and normal glucose challenge test (GCT), and to evaluate the factors associated with LGA. A total of 480 pregnant women at risk for gestational diabetes mellitus (GDM); 160 with a false positive GCT and 320 with normal GCT results were included. The incidence of LGA and other pregnancy outcomes were compared between the two groups. Possible associated factors for LGA were also evaluated. Women with a false positive GCT were significantly older and more likely to be multiparous. The incidence of LGA was comparable between the false positive and normal GCT groups (15.6% vs. 13.1%, p = .456). Other pregnancy outcomes were also comparable. Logistic regression analysis showed that pre-pregnancy underweight significantly reduced the risk of LGA (adjusted OR 0.25, 95% CI 0.07-0.87, p = .029) while a second trimester weight gain >7 kg significantly increased the risk of LGA (adjusted OR 3.13, 95% CI 1.67-5.89, p < .001). Impact Statement What is already known on this subject? Women with a false-positive GCT (abnormal GCT but normal OGTT) can be considered as having an early form of glucose intolerance which similar adverse outcomes to GDM could develop. Previous studies have reported that a mild maternal hyperglycaemia in the absence of GDM is associated with LGA, macrosomia, shoulder dystocia and a caesarean delivery. There is no current recommendation for any intervention or treatment among women with a false positive GCT. What the results of this study add? The results of this study showed that an incidence of LGA was not significantly increased in the false positive GCT groups and that other pregnancy outcomes were comparable. A pre-pregnancy underweight significantly reduced the risk of LGA while a second trimester weight gain >7 kg significantly increased the risk of LGA. What the implications are of these findings for clinical practice and/or further research? As a gestational weight gain is modifiable, behavioural and a dietary intervention as well as a close monitoring of the weight gain could help in lowering the risk of LGA, even in the absence of GDM. Further studies which are more widely generalisable are needed to elucidate the relationship between 50 g GCT and the adverse outcomes and to investigate the benefits of a specific intervention among this specific group of women.

The aims of this study were to determine prevalence of childbirth fear among uncomplicated pregnant women in Siriraj Hospital and possible associated factors. A total of 305 uncomplicated, singleton pregnant women were enrolled during early third trimester. All participants were interviewed regarding baseline demographic, social, economic, family, and obstetric characteristics. Fear of childbirth (FOC) was evaluated by Thai version of Wijma Delivery Expectancy/Experience Questionnaire Version A (W-DEQ). W-DEQ scores and level of FOC were compared between various characteristics to determine possible associated factors. Mean W-DEQ score was 51.9. Prevalence of low, moderate, high, and severe FOC were 18.4%, 64.9%, 16.1%, and 0.7%, respectively. Mean FOC score was significantly higher in women with unplanned than planned pregnancy (p = .033). Women with high to severe FOC were significantly less likely to have adequate income (p = .03), have family support (p = .02), have been told about delivery (p = .03), and have witnessed delivery (p = .01). IMPACT STATEMENT What is already known on this subject? Prevalence of fear of childbirth (FOC) in Western countries varies from 8 to 27%. FOC have been related to several unwanted conditions, including obstetrics complications, operative vaginal delivery, increased analgesic use in labour, elective caesarean section, postpartum depression, and impaired maternal-infant relation. Several factors related to FOC have been reported, including maternal age, parity, gestational age, history of a vacuum or forceps extraction, previous caesarean section, previous adverse perinatal outcome, low education, low socio-economic level, psychiatric problems, personality, lack of social support, and low self-esteem. What do the results of this study add? Prevalence of low, moderate, high, and severe FOC in Siriraj Hospital were 18.4%, 64.9%, 16.1%, and 0.7%, respectively. This was relatively lower than those reported from Western countries. Mean FOC score was significantly higher in women with unplanned than planned pregnancy. High to severe FOC was significantly related to low financial and family support and less understandings on delivery process. Differences in the results might be partly due to the differences in study population characteristics of Thais, including ethnics, religions, beliefs, perceptions, social structures, and social norms. What are the implications of these findings for clinical practice and/or further research? Future researches are suggested to explore and understand more about social and cultural factors associated with FOC. Identification of women with high or severe degree of FOC could help in preparing the women at risk before or during pregnancy to lessen FOC in order to improve their childbirth experiences. In addition, effective interventions to reduce FOC should be developed, evaluated, and implemented in the future.

AIMS: The objective of this study was to determine the relationship between second trimester weight gain and the risk of gestational diabetes (GDM) after normal first trimester screening. METHODS: A total of 195 women at risk for GDM who had normal first trimester screening results were enrolled. The study group consisted of 65 women who had second trimester weight gain > 7 kg, while another 130 women with weight gain ≤ 7 kg served as the comparison group, matched 1:2 by pre-pregnancy body mass index. GDM screening was repeated during 24-28 weeks of gestation and the incidence of GDM was compared between the groups. Other possible associated factors were evaluated. RESULTS: Mean age, pre-pregnancy body mass index, parity, GDM risks, first trimester weight gain, timing of GDM screening and initial test results were comparable between the groups. The incidence of GDM was significantly higher in the study than in the comparison group (24.6% vs 10.8%, P = 0.012). Logistic regression analysis showed that second trimester weight gain >7 kg and an abnormal 1 oral glucose tolerance test value on first trimester screening independently increased the risk of GDM (adjusted odds ratio 2.6, 95% confidence interval 1.13-6.0, P = 0.025 and 8.36, 95% confidence interval 2.62-26.66, P < 0.001, respectively). CONCLUSION: Second trimester weight gain > 7 kg and an abnormal 1 oral glucose tolerance test value at first screening increased the risk of GDM in at-risk women.

AIMS: To compare the incidence of large-for-gestational-age (LGA) infants in women diagnosed with gestational diabetes mellitus (GDM) early and late in pregnancy, and evaluate associated factors. METHODS: A total of 284 women with GDM who commenced antenatal care before 20 weeks of gestation were enrolled: 142 were diagnosed before 20 weeks (early GDM) and 142 were diagnosed after 20 weeks of gestation after normal initial screening tests (late GDM). Incidence of LGA infants were compared. Factors associated with LGA and pregnancy outcomes were evaluated. RESULTS: Both groups had comparable baseline characteristics. The late GDM group were more likely to gain weight greater than recommended (P = 0.009) and less likely to have optimal glycemic control (P = 0.035). Incidences of maternal and neonatal complications, including LGA, were not significantly different between the groups. Logistic regression analysis demonstrated that the timing of GDM diagnosis was not significantly associated with LGA. Less gestational weight gain than recommended decreased the risk of LGA by 76% (adjusted odds ratio [OR] 0.24, 95% confidence interval [CI] 0.09-0.67, P = 0.007), while gestational weight gain greater than recommended doubled the risk of LGA (adjusted OR 1.99, 95% CI 1.03-3.87, P = 0.041). Good glycemic control also reduced the risk of LGA by 66% (adjusted OR 0.34, 95% CI 0.16-0.71, P = 0.886). CONCLUSION: Gestational weight gain and glycemic control, but not timing of diagnosis, were independently associated with LGA in women with GDM. Women diagnosed with GDM early had similar rates of LGA infants as women diagnosed late.

OBJECTIVES: This study aims to evaluate the prevalence of pregnant women whose children are at higher risk for childhood allergies and to assess knowledge of risk assessment and prevention strategies. METHODS: A cross-sectional study was conducted on 310 pregnant women in an antenatal care clinic at a tertiary care hospital in Thailand. In addition to baseline demographic and obstetric characteristics, all participating pregnant women were asked to complete a questionnaire regarding risk evaluation and knowledge of childhood allergies on various topics. A childhood allergy risk assessment was evaluated based on the history of allergy disease in immediate family members. The questionnaire on knowledge was derived from a guideline issued by the Allergy, Asthma, and Immunology Association of Thailand, with possible scores of 0-30. RESULTS: The mean maternal age was 30.6 years, and 139 (44.8%) were nulliparous. Overall, 86 couples (27.7%) were at high risk for childhood allergies. The mean total knowledge score was 15.2 out of 30, and only 24 women (7.7%) had an overall score of >20, and 40 women (12.9%) had an overall score of ≤10. The mean knowledge score for almost every subtopic was less than half of the possible points, except for the risk reduction strategies during pregnancy. Comparisons between those with higher and lower scores (≥16 vs. ≤15 points) showed that women with higher knowledge scores were significantly more likely to have had a previous child with an allergy (p=0.010). CONCLUSION: The prevalence of pregnant women whose children were at higher risk for childhood allergies was 27.7% (86 of 310 couples). The women had limited knowledge of childhood allergies with regard to risk assessment, risk reduction strategies, and various interventions. The only factor associated with a higher knowledge score was having a previous child with an allergy.
RESUMO
Objective: To determine the risk factors associated with late-onset GDM (diagnosed between 24 and 28 weeks of gestation) after normal early screening. Methods: A case-control study was conducted in 600 singleton pregnant women who started antenatal care before 20 weeks with normal early GDM screening. Repeat screening was performed at 24-28 weeks. Cases were 120 women with late-onset GDM and 480 controls were those without GDM. Risk factors for late-onset GDM were evaluated and pregnancy outcomes were compared. Results: Cases were significantly older, and more likely to be overweight or obese. 50-g GCT of ≥ 160 mg/dL and abnormal 1 value of 100-g OGTT significantly increased the risk of late-onset GDM (p = 0.004 and < 0.001 respectively). Independent risk factors were abnormal 1 value of 100-g OGTT from first screening (adjusted OR 5.49, 95% CI 2.70-11.17, p < 0.001), age ≥ 30 years (adjusted OR 2.71, 95% CI 1.66-4.43, p < 0.001), DM in family (adjusted OR 1.76, 95% CI 1.07-2.88, p = 0.025), and BMI ≥ 25 kg/m2 (adjusted OR 1.86, 95% CI 1.17-2.97, p = 0.009). Late-onset GDM significantly increased the risk of preeclampsia, cesarean delivery, LGA, and macrosomia. Conclusion: Independent factors associated with late-onset GDM included abnormal 1 value of 100-g OGTT from first screening, age ≥ 30 years, DM in family, and being overweight or obese.
RESUMO
Objectives: To determine the incidence of overt diabetes in pregnancy (ODIP) among women with 50-g GCT results ≥ 200 mg/dL and compare characteristics and pregnancy outcomes between women with and without gestational diabetes (GDM). Methods: A retrospective cohort study was conducted in 212 pregnant women whose 50-g GCT results ≥ 200 mg/dL. ODIP was diagnosed from 75-g OGTT if fasting plasma glucose ≥ 126 and/or 2-h plasma glucose ≥ 200 mg/dL. Various characteristics and pregnancy outcomes were compared between ODIP and those with and without GDM. Results: Incidence of ODIP was 1.9% of all pregnant women and 23.6% of women with 50-g GCT ≥ 200 mg/dL. Women with ODIP and GDM were more likely to be overweight or obese than those without GDM (52%, 39.6%, and 18.2%, p < 0.001). Women with ODIP had significantly higher 50-g GCT results, lower gestational weight gain, and were less likely to deliver vaginally. Insulin therapy was significantly more common in women with ODIP compared to GDM (70.2% vs. 15.4%, p < 0.001). Rates of LGA, macrosomia, and other neonatal outcomes were comparable. BMI ≥ 25 kg/m2 and 50-g GCT ≥ 240 mg/dL independently increased the risk of any abnormal glucose tolerance [adjusted OR 3.22 (95% CI 1.55-6.70) and 2.28 (95% CI 1.14-4.58)] and ODIP [adjusted OR 9.43 (95% CI 2.15-41.38) and 6.36 (95% CI 2.85-14.18)], respectively. Conclusion: Incidence of ODIP was 23.6% of women with 50-g GCT ≥ 200 mg/dL. BMI ≥ 25 kg/m2 and 50-g GCT ≥ 240 mg/dL independently increased the risk of GDM and ODIP. Neonatal complications were comparable between ODIP and those with and without GDM.
RESUMO
Objectives: To determine the incidence of excessive gestational weight gain (GWG) among overweight and obese pregnant women, its associated factors, and pregnancy outcomes. Methods: A total of 355 overweight or obese singleton pregnant women who received antenatal care and delivered at Siriraj Hospital were included. Data, including obstetric characteristics, weight gain, and pregnancy outcomes, were extracted from medical records. GWG was categorized according to the Institute of Medicine recommendation. Comparisons were made between individuals with inadequate, normal, and excessive GWG. Logistic regression analysis was performed to determine independent associated factors for excessive GWG. Results: Majority of the women were overweight (68.7%), 38.9% were nulliparous, and mean pre-pregnancy body mass index was 28.9 kg/m2. Excessive GWG was observed in 53% of the women. Women with excessive GWG had significantly higher weight gain in every trimester. Risk of excessive GWG increased in women ≤30 years of age, while gestational diabetes (GDM) significantly decreased the risk. Women with excessive GWG had a significantly higher primary cesarean section rate. Both women with normal and excessive GWG showed higher rate of having large for gestational age (LGA) infants (P=0.003). Maternal age of ≤30 years significantly increased the risk of excessive GWG (adjusted odds ratio [OR], 1.91; 95% confidence interval [95% CI], 1.11-3.27) and GDM significantly decreased this risk (adjusted OR, 0.40; 95% CI, 0.24-0.67). Conclusion: The incidence of excessive GWG among overweight and obese women was 53%. Maternal age of ≤30 years significantly increased this risk while women with GDM were at significantly decreased risk. Rates of primary cesarean section and fetal LGA significantly increased in women with excessive GWG.
RESUMO
Objective The aim of this study is to compare the rate of spontaneous preterm delivery between gestational diabetes mellitus (GDM) and normal pregnancy. Pregnancy outcomes and associated risk factors for spontaneous preterm delivery were evaluated. Methods A retrospective cohort study was conducted on 120 GDM and 480 normal pregnant women. All women received GDM screening with 50-g glucose challenge test and 100-g oral glucose tolerance test at the first visit and repeated at 24-28 weeks. Data were retrieved from medical records and included baseline and obstetric characteristics, preterm risks, GDM risks, and pregnancy outcomes. Spontaneous preterm birth was defined as delivery before 37 completed weeks of gestation that had been preceded by spontaneous labor. Results GDM women were more likely to be ≥30 years (p=0.032) and have previous GDM (p=0.013). Incidence of overall preterm delivery was significantly higher in GDM women (17.5% vs. 8.5%, p=0.004), as well as the incidence of spontaneous preterm delivery (15.8% vs. 7.1%, p=0.004). GDM women had less gestational weight gain (p<0.001) and were less likely to have excessive weight gain (p=0.002). GDM women were more likely to deliver large for gestational age (LGA) (p=0.02) and macrosomic infants (p=0.027). Neonatal hypoglycemia was significantly more common among GDM women (p=0.013). Multivariate analysis showed that previous preterm birth and GDM independently increased the risk of spontaneous preterm delivery (adjusted OR: 2.56, 95% CI: 1.13-5.79, p=0.024, and adjusted OR: 2.15, 95% CI: 1.2-3.84, p = 0.010, respectively). Conclusion GDM and previous preterm birth significantly increased the risk of spontaneous preterm delivery. GDM also increased the risk of LGA, macrosomia, and neonatal hypoglycemia.
RESUMO
BACKGROUND: Prepregnancy underweight, and gestational weight gain has been associated with increased risk of adverse pregnancy outcomes, including preterm birth, low birthweight (LBW) and small for gestational age (SGA), but with conflicting results. The objectives were to compare the incidence of SGA, LBW, and other pregnancy outcomes between prepregnancy underweight and normal weight women and to evaluate possible associated risk factors. METHODS: A retrospective cohort study was conducted in 220 underweight women (prepregnancy BMI of <18.5 kg/m2) and 440 normal weight women (prepregnancy BMI 18.5-24.9 kg/m2). Data were extracted from medical records and compared between the 2 groups, including baseline and obstetric characteristics, labor and delivery data, pregnancy, and neonatal outcomes. RESULTS: Underweight women were significantly younger and more likely to be nulliparous. They were significantly more likely to have weight gain below recommendation (33.6% vs. 23.2%, P<0.001). SGA and LBW were significantly more common in underweight compared to normal weight women (10.9% vs. 7%, P=0.034 and 13.2 vs. 7.3%, P=0.013, respectively). Other adverse neonatal outcomes were comparable. Logistic regression analysis showed that inadequate weight gain was the independent risk for both SGA and LBW (adjusted OR 2.20, 95%CI 1.19-4.09, P=0.012) and adjusted OR 2.31, 95%CI 1.28-4.159, P=0.005, respectively). CONCLUSIONS: Risk of both SGA and LBW were significantly increased in underweight compared to normal weight women. Inadequate weight gain was independently associated with increased risk of both SGA and LBW.

Objectives The objective of this study was to determine the incidence of preeclampsia and associated cesarean section (CS) rate according to the Robson classification. Methods A retrospective cross-sectional study was conducted on a total of 670 women who delivered at a tertiary care hospital in Thailand during January to March 2023. All women were classified into 10 groups according to the Robson classification, and preeclampsia was identified. Overall and group-specific incidence of preeclampsia and CS rate were estimated. Comparison of CS rate was made between those with and without preeclampsia using the Chi-squared test. Relative risks (RR) and corresponding 95% confidence intervals were estimated. Results The majority of women were in group 1 (34%) and group 3 (30.7%). Overall CS rate was 40.6% with highest contribution from group 1, 5, and 10. Incidence of preeclampsia was 9.1%, and the majority were in groups 10 (29.5%) and 1 (23%). Preeclampsia significantly increased the rate of overall CS (RR 1.8, p<0.001). The risk of CS significantly increased in group 1 (RR 1.8, p=0.043), group 3 (RR 3.5, p=0.025), and group 10 (RR 1.9, p=0.006). Preeclampsia accounted for 15.4% of all CS, with the highest contribution in group 2 (37.5%), group 10 (31.1%), group 3 (16.7%), and group 1 (10.8%). Without preeclampsia, the overall CS rate was relatively reduced by 6.9%, with the largest relative reduction in group 10 (14.3%), group 3 (11.5%), group 2 (6.3%), and group 1 (5.2%). Conclusion The incidence of preeclampsia was 9.1%, and preeclampsia significantly increased the rate of overall CS. Without preeclampsia, overall CS rate relatively reduced by 6.9% but did not significantly change the relative contribution of CS according to the Robson classification.
RESUMO
BACKGROUND: Body mass index (BMI) has commonly been used to evaluate the risk of gestational diabetes mellitus (GDM), but BMI does not always represent body fat mass distribution. Body fat index (BFI), which includes the measurement of subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT), has been suggested to be a better predictor for GDM than BMI. OBJECTIVE: The objective of this study is to compare the risk of GDM among pregnant females with BFI of >0.5 and ≤0.5. METHODS: Maternal abdominal subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT) thickness were measured by ultrasonography before 14 weeks of gestation, and BFI was calculated (VAT×SAT/height). The study group was 160 females with BFI of >0.5, and the comparison group was 80 females with BFI of ≤0.5. All females received GDM screening during the first antenatal visit and at 24-28 weeks of gestation. The rate of GDM was compared between the two groups. The correlation between BFI and BMI and their diagnostic ability for GDM were evaluated. Logistic regression analysis was performed to determine the independent associated factors for GDM. RESULTS: Females with BFI of >0.5 were significantly older (p=0.033) and had higher body mass index (BMI) (p<0.001) and were more likely to be overweight or obese (p<0.001). BFI correlated well with BMI (correlation coefficient of 0.736, p<0.001). GDM was significantly more common in females with BFI of >0.5 (24.4% versus 11.3%, p=0.017). The diagnostic ability for GDM between BFI and BMI was similar (areas under receiver operating characteristic {ROC} curves of 0.641 and 0.646, respectively). Significant independent risk factors for GDM were a BFI of >0.5 and a BMI of ≥25 kg/m2 (adjusted odds ratio {OR}, 3.8; 95% confidence interval {CI}, 1.5-9.2), age of ≥30 years (adjusted OR, 2.8; 95% CI, 1.2-6.4), and family history of diabetes mellitus (DM) (adjusted OR, 4.0; 95% CI, 1.9-8.3). CONCLUSION: Females with BFI of >0.5 were significantly more likely to have GDM. The diagnostic ability of BFI and BMI for GDM was comparable. Females with BFI of >0.5 and BMI of ≥25 kg/m2 have an increased risk for GDM.
RESUMO
INTRODUCTION: Aberrant immune and inflammatory response is thought to be involved in the pathogenesis of gestational diabetes mellitus (GDM). OBJECTIVE: To investigate the genetic polymorphisms and levels of adipokines/adipocytokines that influence the risk of developing GDM in Thai women. RESEARCH DESIGN & METHODS: This case-control recruited 400 pregnant Thai women. A total of 12 gene polymorphisms at ADIPOQ, adipsin, lipocalin-2, PAI-1, resistin, IL-1ß, IL-4, IL-17A, TGF-ß, IL-10, IL-6, and TNF-α were analyzed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay and RNase H2 enzyme-based amplification (rhAmp) SNP assay. Serum levels of adipokines/adipocytokines were evaluated using Luminex assays. RESULTS: Mean age, weight before and during pregnancy, body mass index before and during pregnancy, blood pressure, gestational age at blood collection, and median 50 g glucose challenge test were significantly higher in GDM women than control. Significantly lower adiponectin and higher IL-4 levels were found in GDM compared to controls (p = 0.001 and p = 0.03, respectively). The genotype frequencies of IL-17A (rs3819025) were significantly different between GDM and controls (p = 0.01). Using additive models, IL-17A (rs3819025) and. TNF-α (rs1800629) were found to be independently associated with increased risk of GDM (odds ratio [OR]: 2.867; 95 % confidence interval [CI]: 1.171-7.017; p = 0.021; and OR: 12.163; 95 %CI: 1.368-108.153; p = 0.025, respectively). In GDM with IL-17A (rs3819025), there was a significant negative correlation with lipocalin-2 and PAI-1 levels (p = 0.038 and p = 0.004, respectively). CONCLUSION: The results of this study highlight the need for genetic testing to predict/prevent GDM, and the importance of evaluating adipokine/adipocytokine levels in Thai GDM women.

Background: Gestational diabetes mellitus (GDM) is the most common association with hyperglycemia and glucose intolerance during pregnancy. The adipokines play an important to control insulin secretion and glucose. This study aimed to investigate the association between maternal circulating adipokine levels and ADIPOQ gene polymorphism among pregnant women subjects with GDM and normal glucose tolerance (NGT). Methods: Participants including 229 normal pregnant women and 197 GDM pregnant women were enrolled from 2015 to 2018 at Siriraj hospital. Serum adipokine levels including adiponectin, adipsin/factor D, NGAL/Lipocalin-2, total PAI-1, and resistin were measured by immunoassay. ADIPOQ variations were investigated including -11377C/G (rs266729), +45T/G (rs2241766), and +276G/T (rs1501299). Results: Serum adiponectin concentration was also significantly decreased among the GDM who had aged less than 35 years old whereas adipsin levels were significantly lower among the GDM who had aged more than 35 years old. Also, adiponectin and total PAI-1 levels were significantly lower among the GDM who had a BMI of less than 30 kg/m2. The G allele frequency of ADIPOQ +45T/G was significantly different between GDM and controls (p = 0.03). ADIPOQ +45T/G was associated with an increased risk of GDM (odds ratio [OR]: 1.554; 95% confidence interval [CI]: 1.010-2.390; p=0.045). The -11377C/G was affected by the level of adiponectin (p = 0.04). The C allele of -11377C/G SNP declined serum adiponectin levels and may be a risk factor for GDM. Conclusion: This study revealed that genetics play important roles in circulating adipokines among pregnant women. ADIPOQ polymorphisms had significant associations with adiponectin levels in GDM patients.
RESUMO
AIM: The aim of this study was to determine the correlation between cord blood and maternal serum magnesium levels among pre-eclamptic pregnant women treated with magnesium sulfate. MATERIALS AND METHODS: A total of 36 pregnant women, >28weeks' gestation, diagnosed with pre-eclampsia and treated with magnesium sulfate (MgSO(4) ), were enrolled. Maternal and umbilical cord blood samples were obtained immediately after delivery and sent for determination of magnesium and calcium levels. RESULTS: Mean maternal age was 27.4±6.4years and mean gestational age was 38.1±1.8weeks. Most were diagnosed with pre-eclampsia (94.5%), others had HELLP syndrome. Mean total MgSO(4) the women received was 14.4±6.0g and mean duration of treatment was 5.1±3.3h. Mean maternal serum and cord blood magnesium levels were 2.2±0.4 and 1.8±0.3mmol/L, respectively. Maternal magnesium and calcium levels showed significant positive correlation with their levels in cord blood (P<0.001). Significant positive correlation was found between total dose as well as duration of MgSO4 and maternal and cord blood magnesium levels (P<0.001) but was inversely correlated with maternal and cord blood calcium levels. CONCLUSIONS: Maternal serum magnesium and calcium levels were correlated with cord blood levels in pre-eclamptic pregnant women who received MgSO4 therapy.
