RESUMEN
OBJECTIVES: Pre-eclampsia (PE) and gestational hypertension (GH) are two different categories of hypertensive disorders of pregnancy. Given earlier observational research, the relationship between sex hormone-binding globulin (SHBG) and a higher risk of GH/PE is still up for dispute. Hence, the present investigation aimed to examine the possible link between SHBG and the likelihood of GH/PE. METHODS: As a first stage, single nucleotide polymorphisms from summary-level genome-wide association studies were tightly screened using quality-control techniques. Afterward, we utilized a two-sample Mendelian randomization (MR) study to examine the causal impact of SHBG on the likelihood of GH/PE. There was no indication of a relationship between blood SHBG level (n = 214,989) and GH/PE (1864 cases and 461,069 controls) in the initial study. Consensus results were obtained from the replicated analysis, which utilized MR estimates based on serum SHBG level(n = 214,989) for GH (4255 cases and 114,735 controls). RESULTS: The findings did not indicate any proof of a cause-and-effect connection between SHBG and the likelihood of GH/PE (odds ratio [OR] = 0.99, 95% confidence interval [CI] = 0.999 - 1.00, p = .34). Replicate analysis also revealed similar patterns (OR = 0.92, 95%CI = 0.82-1.05, p = .21). The above findings were demonstrated to have a strong level of robustness. CONCLUSIONS: The findings of this research did not offer definitive proof to endorse the idea that SHBG has a direct causal impact on the likelihood of GH/PE, which goes against numerous widely accepted observational studies. To ascertain the potential processes behind the relationships seen in observational studies, more investigation is needed.

BACKGROUND: Little is known about the relationship of healthy diets, which are widely recommended to prevent diseases in general populations, with the risk of hypertensive disorders of pregnancy (HDP), particular among non-Western populations with different dietary habits. We aimed to investigate the association between periconceptional diet quality and the risk of HDP among pregnant Japanese women. METHODS AND RESULTS: Dietary intake over 1 year before the first trimester of pregnancy was assessed using a validated, self-administered food frequency questionnaire among 81 113 pregnant Japanese women who participated in a prospective cohort of the Japan Environment and Children's Study. Overall diet quality was assessed by the Balanced Diet Score (BDS) based on adherence to the country-specific dietary guidelines and the Dietary Approaches to Stop Hypertension (DASH) score. Cases of HDP were identified by medical record transcription. The association between diet quality and HDP risk was examined using Bayesian logistic regression models with monotonic effects. We identified 2383 (2.9%) cases of HDP. A higher BDS was associated with a lower risk of HDP. When comparing the highest with the lowest quintile of the BDS, the adjusted odds ratio (aOR) of HDP was 0.83 (95% credible interval [CrI], 0.73-0.94). The DASH score and HDP risk were inversely associated in a monotonic dose-response manner (aOR per 1-quintile increase in the DASH score, 0.92 [95% CrI, 0.89-0.95]). CONCLUSIONS: A high-quality diet, which is recommended for disease prevention in general populations, before conception may also reduce the risk of HDP among pregnant Japanese women.

The relationships between the exposure to ambient air pollutants during gestation and the incidence of hypertensive disorders in pregnancy (HDPs) or preeclampsia are contradictory. This prospective cohort study enrolled the participants between January 2020 and December 2021 from the Maternal and Child Health Hospital of Hubei Province, Tongji Medical College, Huazhong University of Science and Technology. The exposure to ambient air pollutants and daily temperatures were obtained from the ChinaHighAirPollutants dataset and the Big Earth Data Platform for Three Poles, respectively. Logistic regression models were used as single- and two-pollutant models. Restricted cubic splines were applied to each ambient air pollutant exposure to further evaluate the exposure-response relationships. Quantile G-computation approaches were employed to evaluate the cumulative impact of mixed ambient air pollutants on the incidence risk HDPs and preeclampsia. Among 19,325 participants (median age: 30.2 years), 1669 (8.64%) were diagnosed with HDPs and 180 (0.94%) with preeclampsia. While mostly null risk estimates were observed, exposure to PM1, PM2.5, PM10, and NO2 correlated with a decreased incidence risk for HDPs and preeclampsia during most gestational periods. Additionally, our multi-pollutant model presented that an increase by one quartile in the cumulative effect of ambient air pollutants was associated with a significantly decreased incidence risk for HDPs in the trimester before gestation and in the third trimester during gestation, as well as for preeclampsia in the third trimester during gestation. These findings warrant further investigation into the mechanisms underlying these associations.

INTRODUCTION: Blood pressure assessment is an essential strategy for early detection and treatment of hypertension and hypotension. Hypertensive disorders of pregnancy (HDP) are major public health problems resulting in a significant burden of perinatal and maternal morbidity and mortality. In Ethiopia, among pregnancies complicated by HDP, 25% end up with perinatal death. Perinatal and maternal mortality related to HDP were found to be higher in Ethiopia compared to high-income and most of the low- and middle-income countries. Despite its importance, there is limited evidence on blood pressure assessment during pregnancy. Therefore, this study aimed to determine the prevalence of blood pressure assessment during pregnancy and its associated factors in Ethiopia. METHODS: This study was based on the 2019 Mini Ethiopian Demographic and Health Survey data. A total weighted sample of 2923 women who had a live birth five years before the survey were included and Stata version 16 software was used for statistical analysis. To identify associated factors, a multilevel robust Poisson regression model was fitted since the prevalence of blood pressure assessment was higher than 10%. Variables with p-value < 0.2 in the bi-variable analysis were exported to the multivariable analysis. In the multivariable analysis, the adjusted prevalence ratio with its 95% confidence interval was used to declare a statistically significant association. RESULTS: In Ethiopia, the prevalence of blood pressure assessment during pregnancy was 88.1% (95% CI: 86.9%, 89.2%). In the multivariable multilevel robust Poisson analysis, primary education and secondary education, grand-multiparity, initiation of antenatal care before three months and 3-6 months, four and above antenatal care visits, being counselled by a health professional, being from richer and richest households, residing in Afar and Amhara regions were significantly associated with BP assessment during pregnancy in Ethiopia. CONCLUSION AND RECOMMENDATIONS: To reduce the high burden of mortality related to hypertensive disorders of pregnancy in the country, blood pressure assessment should be improved. Therefore, policymakers should design interventions that empower women in terms of education and economy, promoting early initiation of antenatal care visits and prenatal counselling could improve blood pressure assessment.

BACKGROUND: Phenols and parabens are two classes of high production volume chemicals that are used widely in consumer and personal care products and have been associated with reproductive harm and pregnancy complications, such as preeclampsia and gestational diabetes. However, studies examining their influence on maternal blood pressure and gestational hypertension are limited. OBJECTIVES: We investigated associations between individual phenols, parabens, and their mixture on maternal blood pressure measurements, including systolic and diastolic blood pressure (SBP and DBP) and hypertension during pregnancy (defined as stage 1 or 2 hypertension), among N=1,433 Puerto Rico PROTECT study participants. METHODS: We examined these relationships cross-sectionally at two time points during pregnancy (16-20 and 24-28 wks gestation) and longitudinally using linear mixed models (LMMs). Finally, we used quantile g-computation to examine the mixture effect on continuous (SBP, DBP) and binary (hypertension during pregnancy) blood pressure outcomes. RESULTS: We observed a trend of higher odds of hypertension during pregnancy with exposure to multiple analytes and the overall mixture [including bisphenol A (BPA), bisphenol S (BPS), triclocarbon (TCC), triclosan (TCS), benzophenone-3 (BP-3), 2,4-dichlorophenol (2,4-DCP), 2,5-dichlorophenol (2,5-DCP), methyl paraben (M-PB), propyl paraben (P-PB), butyl paraben (B-PB), and ethyl paraben (E-PB)], especially at 24-28 wk gestation, with an adjusted mixture odds ratio(OR)=1.57 (95% CI: 1.03, 2.38). Lower SBP and higher DBP were also associated with individual analytes, with results from LMMs most consistent for methyl paraben (M-PB) or propyl paraben (P-PB) and increased DBP across pregnancy [adjusted M-PB ß=0.78 (95% CI: 0.17, 1.38) and adjusted P-PB ß=0.85 (95% CI: 0.19, 1.51)] and for BPA, which was associated with decreased SBP (adjusted ß=-0.57; 95% CI: -1.09, -0.05). Consistent with other literature, we also found evidence of effect modification by fetal sex, with a strong inverse association observed between the overall exposure mixture and SBP at visit 1 among participants carrying female fetuses only. CONCLUSIONS: Our findings indicate that phenol and paraben exposure may collectively increase the risk of stage 1 or 2 hypertension during pregnancy, which has important implications for fetal and maternal health. https://doi.org/10.1289/EHP14008.

Importance: Women who had a hypertensive disorder of pregnancy (HDP) have a well-documented risk of chronic hypertension within a few years of delivery, but management of postpartum hypertension among these women remains inconsistent. Objective: To assess the incidence of initiation of antihypertensive medication use in the first 2 years after delivery by HDP status and antenatal antihypertensive medication use. Design, Setting, and Participants: This Danish register-based cohort study used data from women with at least 1 pregnancy lasting 20 or more gestational weeks (only the first pregnancy in the period was considered) who delivered from January 1, 1995, to December 31, 2018. Statistical analysis was conducted from October 2022 to September 2023. Exposure: Hypertensive disorders of pregnancy. Main Outcomes and Measures: Cumulative incidences and hazard ratios of initiating antihypertensive medication use within 2 years post partum (5 postpartum time intervals) by HDP status and antenatal medication use. Results: The cohort included 784â¯782 women, of whom 36â¯900 (4.7% [95% CI, 4.7%-4.8%]) had an HDP (HDP: median age at delivery, 29.1 years [IQR, 26.1-32.7 years]; no HDP: median age at delivery, 29.0 years [IQR, 25.9-32.3 years]). The 2-year cumulative incidence of initiating postpartum antihypertensive treatment ranged from 1.8% (95% CI, 1.8%-1.8%) among women who had not had HDPs to 44.1% (95% CI, 40.0%-48.2%) among women with severe preeclampsia who required antihypertensive medication during pregnancy. Most women who required postpartum antihypertensive medication after an HDP initiated use within 3 months of delivery (severe preeclampsia, 86.6% [95% CI, 84.6%-89.4%]; preeclampsia, 75.3% [95% CI, 73.8%-76.2%]; and gestational hypertension, 75.1% [95% CI, 72.9%-77.1%]). However, 13.4% (95% CI, 11.9%-14.1%) of women with severe preeclampsia, 24.7.% (95% CI, 24.0%-26.0%) of women with preeclampsia, 24.9% (95% CI, 22.5%-27.5%) of women with gestational hypertension, and 76.7% (95% CI, 76.3%-77.1%) of those without an HDP first filled a prescription for antihypertensive medication more than 3 months after delivery. Women with gestational hypertension had the highest rate of initiating medication after more than 1 year post partum, with 11.6% (95% CI, 10.0%-13.2%) starting treatment after this period. Among women who filled a prescription in the first 3 months post partum, up to 55.9% (95% CI, 46.2%-66.1%) required further prescriptions more than 3 months post partum, depending on HDP status and antenatal medication use. Conclusions and Relevance: In this cohort study of postpartum women, the incidence of initiation of postnatal antihypertensive medication use varied by HDP status, HDP severity, and antenatal antihypertensive medication use. Up to 24.9% of women initiated antihypertensive medication use more than 3 months after an HDP, with up to 11.6% initiating treatment after 1 year. Routine postpartum blood pressure monitoring might prevent diagnostic delays in initiation of antihypertensive medication use and improve cardiovascular disease prevention among women.

OBJECTIVE: This Study aims to investigate the risk factors of hypoglycemia in neonates through meta-analysis. METHOD: PubMed, Embase, Cochrane library, and Web of science databases were searched for case-control studies on risk factors for neonatal hypoglycemia. The search was done up to 1st October 2023 and Stata 15.0 was used for data analysis. RESULTS: A total of 12 published studies were included, including 991 neonates in the hypoglycemic group and 4388 neonates in the non-hypoglycemic group. Meta-analysis results suggested caesarean section [OR = 1.90 95%CI (1.23, 2.92)], small gestational age[OR = 2.88, 95%CI (1.59, 5.20)], gestational diabetes [OR = 1.65, 95%CI (1.11, 2.46)], gestational hypertension[OR = 2,79, 95%CI (1.78, 4.35)] and respiratory distress syndrome[OR = 5.33, 95%CI (2.22, 12.84)] were risk factors for neonatal hypoglycemia. CONCLUSION: Based on the current study, we found that caesarean section, small gestational age, gestational diabetes, gestational hypertension, respiratory distress syndrome are risk factors for neonatal hypoglycemia.

The anthropogenic climate change may impact pregnancy outcomes. Rather than ambient temperature, we aimed to use a composite bioclimatic metric (Universal Thermal Climate Index, UTCI) to identify critical susceptible windows for the associations between bioclimatic exposure and hypertensive disorders of pregnancy (HDPs) risk. Daily UTCI exposure from 12 weeks of preconception through pregnancy was linked to 415,091 singleton pregnancies between 1st January 2000 and 31st December 2015 in Western Australia. Adjusted weekly-specific and cumulative odds ratios (ORs) and 95% confidence intervals (CIs) of gestational hypertension and preeclampsia were estimated with distributed lag non-linear and standard non-linear logistic regressions. Exposures from early pregnancy to week 30 were associated with greater odds of HDPs with critical susceptible windows, particularly elevated at the 1st (10.2 °C) and 99th (26.0 °C) exposure centiles as compared to the median (14.2 °C). The most elevated ORs were 1.07 (95% CI 1.06, 1.08) in weeks 8-18 for gestational hypertension and 1.10 (95% CI 1.08, 1.11) in weeks 11-16 for preeclampsia for the 99th exposure centile. Cumulative exposures associated with HDPs with relatively higher but less precise ORs. The effects of high exposure to HDPs indicated sociodemographic inequalities. The identified critical periods and subpopulations could benefit from climate-related interventions.

OBJECTIVES: Cardiovascular disease is the leading cause of female death worldwide. The link between future cardiovascular events and a history of hypertensive disease in pregnancy or gestational diabetes (GDM) has been well established. Less well understood is the impact on future cardiovascular risk when gestational hypertension (GH) and GDM have occurred together. We assessed the association of GDM and GH with future cardiovascular events both alone and in combination. STUDY DESIGN: All female patients discharged from French hospitals in 2013 with 5 years of subsequent and complete follow-up were identified. They were grouped depending on their history of GDM, history of GH, history of both or history of neither. After propensity score matching, patients with GDM and/or GH were matched 1:1 with patients with no GDM or GH. Hazard ratios (HR) for cardiovascular events during follow-up were adjusted by age at baseline. RESULTS: Women with a history of GH had an increased risk of cardiovascular death (HR 5.46, 95 % confidence interval [CI] 1.93-15.49). Women with a history of GDM had no significant difference in the risk of cardiovascular events such as myocardial infarction (HR 0.88, 95 %CI 0.38-2.03) and cardiovascular death (HR 1.25, 95 %CI 0.47-3.36) during the 5 year follow up. Those with a history of both GDM and GH had a significantly increased risk of myocardial infarction (HR 23.33, 95 %CI 4.84-112.39). CONCLUSION: Women with a history of both GH and GDM are at a 23-fold increased risk of myocardial infarction within the first 5 years of their postnatal lives.

In the southwestern United States, the frequency of summer wildfires has elevated ambient PM2.5 concentrations and rates of adverse birth outcomes. Notably, hypertensive disorders in pregnancy (HDP) constitute a significant determinant associated with maternal mortality and adverse birth outcomes. Despite the accumulating body of evidence, scant research has delved into the correlation between chemical components of wildfire PM2.5 and the risk of HDP. Derived from data provided by the National Center for Health Statistics, singleton births from >2.68 million pregnant women were selected across 8 states (Arizona, AZ; California, CA, Idaho, ID, Montana, MT; Nevada, NV; Oregon, OR; Utah, UT, and Wyoming, WY) in the southwestern US from 2001 to 2004. A spatiotemporal model and a Goddard Earth Observing System chemical transport model were employed to forecast daily concentrations of total and wildfire PM2.5-derived exposure. Various modeling techniques including unadjusted analyses, covariate-adjusted models, propensity-score matching, and double robust typical logit models were applied to assess the relationship between wildfire PM2.5 exposure and gestational hypertension and eclampsia. Exposure to fire PM2.5, fire-sourced black carbon (BC) and organic carbon (OC) were associated with an augmented risk of gestational hypertension (ORPM2.5 = 1.125, 95 % CI: 1.109,1.141; ORBC = 1.247, 95 % CI: 1.214,1.281; OROC = 1.153, 95 % CI: 1.132, 1.174) and eclampsia (ORPM2.5 = 1.217, 95 % CI: 1.145,1.293; ORBC = 1.458, 95 % CI: 1.291,1.646; OROC = 1.309, 95 % CI: 1.208,1.418) during the pregnancy exposure window with the strongest effect. The associations were stronger that the observed effects of ambient PM2.5 in which the sources primarily came from urban emissions. Social vulnerability index (SVI), education years, pre-pregnancy diabetes, and hypertension acted as effect modifiers. Gestational exposure to wildfire PM2.5 and specific chemical components (BC and OC) increased gestational hypertension and eclampsia risk in the southwestern United States.

OBJECTIVE: To explore the relationship between changes in glycated hemoglobin (HbA1c) during the second and third trimesters and adverse pregnancy outcomes among women without hyperglycemia in pregnancy (HIP). RESEARCH DESIGN AND METHODS: A total of 1,057 pregnant women who underwent serum HbA1c and delivered at Women's Hospital, Zhejiang University School of Medicine from May 2022 to March 2023, were included in this study. They were divided into four groups. Associations were evaluated using multivariate logistic regression analysis. RESULTS: In our study, an upward trend in HbA1c levels in the second trimester (HbA1c_S) and third trimester (HbA1c_T) among women without HIP was demonstrated. Multivariate logistics regression analysis showed significant associations: Pregnant women with HbA1c_S<5.5 %, HbA1c_T≥6.1 %, or with HbA1c_S≥5.5 %, HbA1c_T<6.1 % had a significant correlation with hypertensive disorders of pregnancy (HDP) (aOR:2.72, 95 %CI=1.24-5.97ï¼aOR:2.59, 95 %CI=1.15-5.84). Furthermore, for each 1 % increase in the difference value of HbA1c between the second and third trimesters, the risk of HDP increased about 1.96 times, and the risk of delivering a large-for-gestational-age baby increased about 1.30 times. CONCLUSION: Among pregnant women without HIP, elevated HbA1c levels in the second or third trimester are associated with increased risks of adverse pregnancy outcomes.

INTRODUCTION: Women with previous pregnancy-related cardiovascular risk indicators, including gestational diabetes mellitus (GDM) and hypertensive disorders of pregnancy (HDP), have an increased risk of future cardiovascular disease (CVD). Although CVD screening and preventive care beginning in the early postpartum period are recommended, certain barriers limit access to such services. We plan to conduct a scoping review of the literature to explore and summarise evidence on the barriers and facilitators of postpartum CVD preventive services in women with a history of GDM and HDP. METHODS AND ANALYSIS: This scoping review will be conducted in line with the Arksey and O'Malley's (2005) methodological framework and the Joanna Briggs Institute guidance for conducting a systematic scoping review and will follow the Evidence for Policy and Practice Information and the Coordinating Centre at the Institute of Education guidelines. The review results will be reported using the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist. We will search the following databases: Medline, Embase and CINAHL. We will conduct grey literature searches for registered dissertations and theses. Inclusion and exclusion criteria will be kept broad. Qualitative and quantitative studies published in English or French that investigated and reported percieved barriers or facilitators to postpartum CVD screening and preventive care among women with previous GDM and HDP will be included. Individual, interpersonal, organizational, and system level factors will be reported. Qualitative findings will be summarised narratively, and quantitative findings will be absorbed within the themes using the multisource synthesis method. ETHICS AND DISSEMINATION: This review represents one objective of a larger project that was reviewed by the Ottawa Health Sciences Network Research Ethics Board (QI-184). We will disseminate knowledge emanating from this review through open-access publication, presentation/public forums on women's cardiovascular health, women's CVD prevention forums and social media. We will also present the findings of this review at the annual meeting of the Canadian Women's Heart Health Alliance.

BACKGROUND AND AIMS: Adverse pregnancy outcomes (APO) have been related to increased cardiovascular (CV) risk and mortality in later life. Underlying pathomechanisms for the development of CV disease in these women are not yet fully understood. In this study, we aimed to investigate the relationship between APO and individual CV risk profiles in later life. METHODS: We used cross-sectional data from 10,000 participants enrolled in the Hamburg City Health Study (HCHS). We analysed self-reported APO, CV risk factors and health status, including biomarkers, electrocardiogram, echocardiography and vascular ultrasound. To examine associations, Wilcoxon rank sum test and Pearson's χ2-test were performed. Multivariable-adjusted regression models were calculated to determine associations. RESULTS: N = 1970 women who reported pregnancies were included. Median age was 63 years, 8.7 % reported gestational hypertension (gHTN), 18 % excessive weight gain and 2.4 % gestational diabetes. Ten percent had delivered newborns with birth weight <2.5 kg, 14 % newborns with birth weight >4 kg. In multivariable-adjusted models, significant associations between APO, CV risk profiles and cardiac remodeling were identified. gHTN correlated with higher body mass index (BMI) (Beta 1.68, CI 95 % 0.86-2.50; p < 0.001), hypertension (OR 4.58, CI 95 % 2.79-7.86; p < 0.001), left ventricular remodeling (e.g. left ventricular mass index (Beta 4.46, CI 95 % 1.05-7.87; p = 0.010)) and myocardial infarction (OR 3.27, CI 95 % 0.94-10.07; p = 0.046). CONCLUSIONS: In this population-based sample, APO were associated with CV risk profiles and cardiac remodeling in later life, suggesting early manifestations of future CV risk during pregnancy. Prospective data is needed for individual risk stratification in women with APO.

BACKGROUND: This study aims to examine risk of adverse pregnancy outcomes and mothers' characteristics in patients with chronic hypertension, gestational hypertension and preeclampsia. METHODS: The study included all births born from women aged 15-45 years, in Lleida, Spain from 2012 to 2018. Pregnancy outcomes were retrieved by regional administrative databases. Logistic regression analysis was used to calculate adjusted odds ratios (OR) (OR 95% CI) for maternal characteristics or neonatal outcomes. RESULTS: Among 17,177 pregnant women, different types of hypertension present varying risks for both the mother and fetus. There is an increased risk of cesarean section in patients with preeclampsia (OR 2.04, 95% CI: 1.43-2.88). For the newborn, a higher risk of preterm birth is associated with maternal chronic hypertension (OR 3.09, 95% CI: 1.91-4.83) and preeclampsia (OR 5.07, 95% CI: 3.28-7.65). Additionally, there is a higher risk of low birth weight in cases of maternal chronic hypertension (OR 3.2, 95% CI: 2.04-4.88), preeclampsia (OR 5.07, 95% CI: 3.34-7.52), and gestational hypertension (OR 2.72, 95% CI: 1.49-4.68). Furthermore, only newborns of patients with preeclampsia had a higher risk of an Apgar score lower than 7 in the first minute (OR 2.95, 95% CI: 1.45-5.38). CONCLUSIONS: In the study population adjusted for body weight, the different types of hypertension represent different risks in the mother and foetus. These complications were mostly associated with preeclampsia.

Introduction: preterm births continue to be the main cause of infant and child mortality as well as sensory-motor disabilities and neurodevelopmental difficulties worldwide. The rate of preterm births has been rising, in particular in Algeria. The purpose of this study is to determine the frequency of preterm births in the Oran Wilaya and to identify risk factors. Methods: we used data from a multicentre cross-sectional study carried out in all Public Maternity Hospitals in the Oran Wilaya (13). The study included parturient women who had given birth to a live and/or stillborn child (with birthweights ≥500 g), whose gestational age was greater than or equal to 24-36 weeks of amenorrhoea. Mothers´ demographic, medical and socio-behavioural factors were recorded. Logistic regression was used to study predictors of prematurity. Results: preterm birth rate was 9.9% (45/452). The average age of patients was 30.4±6 years; multiple pregnancies accounted for 2.2% of births. Factors related to prematurity were the risk of premature labour (aOR=4.68; 95% CI: 2.27-9.64), the lack of clinical monitoring of pregnancy (OR=2.83; CI 95%: 1.83-6.05) and gestational hypertension (aOR = 3.69, 95% CI: 1.83-8.8). Conclusion: the rate of preterm births is in line with the rate observed in neighbouring countries. The study identified predictive factors, some of which are already targeted by the national perinatal program. However, it is essential to continue to lead efforts to improve the monitoring and management of pregnancies and premature births at all levels of care.

BACKGROUND: As the global consumption of sugary and non-sugar sweetened beverages continues to rise, there is growing concern about their health impacts, particularly among pregnant women and their offspring. OBJECTIVE: This study aimed to investigate the consumption patterns of various beverages among pregnant women in Shanghai and their potential health impacts on both mothers and offspring. METHOD: We applied a multi-stage random sampling method to select participants from 16 districts in Shanghai. Each district was categorised into five zones. Two towns were randomly selected from each zone, and from each town, 30 pregnant women were randomly selected. Data were collected through face-to-face questionnaires. Follow-up data on births within a year after the survey were also obtained. RESULT: The consumption rates of total beverages (TB), sugar-sweetened beverages (SSB), and non-sugar sweetened beverages (NSS) were 73.2%, 72.8%, and 13.5%, respectively. Logistic regression analysis showed that compared to non-consumers, pregnant women consuming TB three times or less per week had a 38.4% increased risk of gestational diabetes mellitus (GDM) (OR = 1.384; 95% CI: 1.129-1.696) and a 64.2% increased risk of gestational hypertension (GH) (OR = 1.642; 95% CI: 1.129-2.389). Those consuming TB four or more times per week faced a 154.3% higher risk of GDM (OR = 2.543; 95% CI: 2.064-3.314) and a 169.3% increased risk of GH (OR = 2.693; 95% CI: 1.773-4.091). Similar results were observed in the analysis of SSB. Regarding offspring health, compared to non-consumers, TB consumption four or more times per week was associated with a substantial increase in the risk of macrosomia (OR = 2.143; 95% CI: 1.304-3.522) and large for gestational age (LGA) (OR = 1.695; 95% CI: 1.219-2.356). In the analysis of NSS, with a significantly increased risk of macrosomia (OR = 6.581; 95% CI:2.796-13.824) and LGA (OR = 7.554; 95% CI: 3.372-16.921). CONCLUSION: The high level of beverage consumption among pregnant women in Shanghai needs attention. Excessive consumption of beverages increases the risk of GDM and GH, while excessive consumption of NSS possibly has a greater impact on offspring macrosomia and LGA.

BACKGROUND: Elevated maternal serum total bile acids (sTBA) level during pregnancy was associated with adverse fetal outcomes. Women with elevated sTBA could complicate with hepatic dysfunction or vascular disorders (hypertensive disorders of pregnancy, HDP), which aggravated adverse fetal outcomes. However, the relationships among sTBA level, hepatic dysfunction, HDP and adverse fetal outcomes were still illusive. OBJECTIVE: We aimed to explore whether hepatic dysfunction or vascular disorders (HDP) mediated the associations between elevated sTBA level and adverse fetal outcomes. METHODS: A large retrospective cohort study encompassing 117,789 Chinese pregnant women with singleton delivery between Jan 2014 and Dec 2022 was conducted. Causal mediation analysis was applied to assess the mediating role of hepatic dysfunction (alanine transaminase > 40 U/L) or HDP in explaining the relationship between high maternal sTBA level (≥10 µmol/L) and adverse fetal outcomes, including low birth weight (LBW), small for gestational age (SGA), and preterm birth (PTB). RESULTS: sTBA level were positively associated with LBW (adjusted odds ratio (aOR) = 1.40; [95 % confidence interval (CI): 1.24-1.59]), SGA (aOR=1.31; [95 % CI: 1.18-1.46]), and PTB (aOR=1.27; [95 % CI: 1.15-1.41]), respectively. The estimated proportions of the total associations mediated by HDP were 47 % [95 % CI: 31 %-63 %] for LBW, 24 % [95 % CI: 13 %-35 %] for SGA, and 34 % [95 % CI: 19 %-49 %] for PTB, excepting the direct effects of high sTBA level. The contribution of hepatic dysfunction as a mediator was weaker on the association between high sTBA level on fetal outcomes, as the proportions mediated and 95 % CI were 16 % [4 %-29 %], 4 % [-6%-14 %], 32 % [15 %-50 %] for LBW, SGA, and PTB, respectively. Moreover, the mediating effect of hepatic dysfunction was nearly eliminated after excluding cases of HDP in the sensitivity analysis. CONCLUSIONS: The substantial mediating effects through HDP highlighted its significant role in adverse fetal outcomes associated with elevated sTBA level. The findings also provoked new insights into understanding the mechanism and developing clinical management strategies (i.e. vascular protection) for adverse fetal outcomes associated with elevated sTBA level.

Importance: Pregnancy may contribute to the development or exacerbation of obstructive sleep apnea (OSA) and increase the risk of gestational complications. Continuous positive airway pressure (CPAP) is the first-line and criterion standard treatment for OSA and is regarded as the most feasible choice during pregnancy. However, the association between CPAP therapy in pregnant women with OSA and reduced gestational complications remains inconclusive. Objective: To investigate the association between CPAP therapy in pregnant women with OSA and the reduction of adverse hypertensive outcomes during gestation. Data Sources: Keyword searches of PubMed, Embase, and the Cochrane Database of Systematic Reviews and Clinical Trials were conducted from inception to November 5, 2023. Study Selection: Original studies reporting the treatment effect of CPAP use on lowering hypertension and preeclampsia risks in pregnant women with OSA were selected. Data Extraction and Synthesis: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline was followed in the reporting of reviews. Data were independently extracted by 2 authors. Random-effects model meta-analyses were performed and risk ratios (RRs) reported. Subgroup analysis, meta-regression based on age and body mass index (BMI; calculated as weight in kilograms divided by height in meters squared), and publication bias assessment were also conducted. Main Outcome and Measures: The primary outcome was the RR of gestational hypertension and preeclampsia between pregnant women with OSA receiving CPAP treatment and those who did not receive CPAP treatment. Results: Six original studies in 809 participants (mean age, 31.4 years; mean BMI, 34.0) were identified and systematically reviewed for meta-analysis. The pooled results showed significant differences between the intervention (CPAP use) and the control (non-CPAP use) groups in reducing the risk of gestational hypertension (RR, 0.65; 95% CI, 0.47-0.89; P = .008) and preeclampsia (RR, 0.70; 95% CI, 0.50-0.98; P = .04). Meta-regression revealed that patients' age (coefficient, -0.0190; P = .83) and BMI (coefficient, -0.0042; P = .87) were not correlated with reduction of risk of hypertension and preeclampsia. Conclusions and Relevance: These findings suggest that implementing CPAP treatment in pregnant women with OSA may reduce the risk of gestational hypertension and preeclampsia.

OBJECTIVE: To examine the association between elevated blood pressure (BP) in the early third trimester and cardiometabolic health 10-14 years after delivery. METHODS: This is a secondary analysis from the prospective HAPO FUS (Hyperglycemia and Adverse Pregnancy Outcome Follow-Up Study). Blood pressure in the early third trimester was categorized per American College of Cardiology/American Heart Association thresholds for: normal BP below 120/80 mm Hg (reference), elevated BP 120-129/below 80 mm Hg, stage 1 hypertension 130-139/80-89 mm Hg, and stage 2 hypertension 140/90 mm Hg or higher. Cardiometabolic outcomes assessed 10-14 years after the index pregnancy were type 2 diabetes mellitus and measures of dyslipidemia, including low-density lipoprotein (LDL) cholesterol 130 mg/dL or higher, total cholesterol 200 mg/dL or higher, high-density lipoprotein (HDL) cholesterol 40 mg/dL or lower, and triglycerides 200 mg/dL or higher. Adjusted analysis was performed with the following covariates: study field center, follow-up duration, age, body mass index (BMI), height, family history of hypertension and diabetes, smoking and alcohol use, parity, and oral glucose tolerance test glucose z score. RESULTS: Among 4,692 pregnant individuals at a median gestational age of 27.9 weeks (interquartile range 26.6-28.9 weeks), 8.5% (n=399) had elevated BP, 14.9% (n=701) had stage 1 hypertension, and 6.4% (n=302) had stage 2 hypertension. At a median follow-up of 11.6 years, among individuals with elevated BP, there was a higher frequency of diabetes (elevated BP: adjusted relative risk [aRR] 1.88, 95% CI, 1.06-3.35; stage 1 hypertension: aRR 2.58, 95% CI, 1.62-4.10; stage 2 hypertension: aRR 2.83, 95% CI, 1.65-4.95) compared with those with normal BP. Among individuals with elevated BP, there was a higher frequency of elevated LDL cholesterol (elevated BP: aRR 1.27, 95% CI, 1.03-1.57; stage 1 hypertension: aRR 1.22, 95% CI, 1.02-1.45, and stage 2 hypertension: aRR 1.38, 95% CI, 1.10-1.74), elevated total cholesterol (elevated BP: aRR 1.27, 95% CI, 1.07-1.52; stage 1 hypertension: aRR 1.16, 95% CI, 1.00-1.35; stage 2 hypertension: aRR 1.41 95% CI, 1.16-1.71), and elevated triglycerides (elevated BP: aRR 2.24, 95% CI, 1.42-3.53; stage 1 hypertension: aRR 2.15, 95% CI, 1.46-3.17; stage 2 hypertension: aRR 3.24, 95% CI, 2.05-5.11) but not of low HDL cholesterol. CONCLUSION: The frequency of adverse cardiometabolic outcomes at 10-14 years after delivery was progressively higher among pregnant individuals with BP greater than 120/80 in the early third trimester.
