Abstract
Perinatal mortality is an indicator that reflects the impact of maternal and infant care in a country. This study presents nine cases of perinatal mortality that occurred in the municipality of Panchimalco, El Salvador. The information was obtained from audit reports. The mothers of the deceased infants were aged between 17 and 43 years, did not use contraceptive methods, had incomplete prenatal controls and averaged a gestational age of 31 weeks. Three deliveries were attended in the community. Most perinatal deaths occurred before delivery due to unknown causes, and live births were preterm. We identified factors such as deficits in comprehensive care for women. Further studies are needed to determine the main factors influencing perinatal deaths in El Salvador. Motivation for the study. It is necessary to understand the maternal and infant characteristics of perinatal deaths. Additionally, it is required to generate evidence that contributes to a better understanding of these events. Main findings. Nine cases of perinatal deaths with maternal-fetal risk characteristics were identified. Most deaths occurred before delivery, with prematurity predominating in the neonates. Implications. Understanding the maternal and infant characteristics of perinatal deaths is essential for developing preventive strategies aimed at reducing risk factors related to perinatal mortality.

Devi TC, Singh HS. Maternal age and adverse pregnancy outcomes among Meitei women of Manipur, Northeast India: A cross-sectional study. Am J Hum Biol 2024; 36:e24029. [PMID: 38108608 DOI: 10.1002/ajhb.24029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2023] [Revised: 11/23/2023] [Accepted: 11/26/2023] [Indexed: 12/19/2023] Open
Abstract
OBJECTIVE The study examines the outcomes of pregnancies conceived at advanced maternal age (AMA) and maternal complications after childbirth among Meitei women of Northeast India. METHOD A total of 760 women participants were included in this study and compared among women aged ≥35 years, with a reference group of women aged 20-34 years. Data on obstetric characteristics were collected after obtaining consent. The data were compared using chi-square analysis, and the results were adjusted using a logistic regression model. Decision trees were developed to predict the potential variables associated with preterm delivery and postpartum complication. RESULTS In the study, 18.95% of AMA women experienced one or more adverse pregnancy outcomes (APOs). Women with AMA are at significantly increased risk of placenta previa (adjusted odds ratio [AOR] = 4.89, 95% confidence interval [CI]: 2.78-8.57), induction of labor (AOR = 3.69, 95%CI: 2.48-5.50), and caesarean section (AOR = 3.42, 95%CI: 2.28-5.12). Moreover, AMA women have a 1.86-2.76 AOR for developing gestational diabetes, pregnancy-induced hypertension, urinary tract infections, preterm delivery, and postpartum complications. Decision tree analysis revealed that AMA and urban residence independently predict preterm delivery and postpartum complications. CONCLUSION The study's findings confirm the adverse impact of AMA on pregnancy outcomes and postpartum complications. Such issues should be addressed, and counseling on the risk of AMA should be provided, particularly for those in the high-risk group. Further prospective studies are needed to understand other potential risk factors of APOs and the impact of AMA complications to prevent the associated burden.

Abstract
Background China's fertility policy has dramatically changed in the past decade with the successive promulgation of the partial two-child policy, universal two-child policy and three-child policy. The trajectories of maternal and neonatal health accompanied the changes in fertility policy are unknown. Methods We obtained data of 280 203 deliveries with six common pregnancy complications and thirteen perinatal outcomes between 2010 and 2021 in eastern China. The average annual percent change (AAPC) was calculated to evaluated the temporal trajectories of obstetric characteristics and adverse outcomes during this period. Then, the autoregressive integrated moving average (ARIMA) models were constructed to project future trend of obstetric characteristics and outcomes until 2027. Results The proportion of advanced maternal age (AMA), assisted reproduction technology (ART) treatment, gestational diabetes mellitus (GDM), anaemia, thrombocytopenia, thyroid dysfunction, oligohydramnios, placental abruption, small for gestational age (SGA) infants, and congenital malformation significantly increased from 2010 to 2021. However, the placenta previa, large for gestational age (LGA) infants and stillbirth significantly decreased during the same period. The AMA and ART treatment were identified as independent risk factors for the uptrends of pregnancy complications and adverse perinatal outcomes. The overall caesarean section rate remained above 40%. Importantly, among multiparas, a previous caesarean section was found to be associated with a significantly reduced risk of hypertensive disorders of pregnancy (HDP), premature rupture of membranes (PROM), placenta previa, placental abruption, perinatal asphyxia, LGA infants, stillbirths, and preterm births. In addition, the ARIMA time series models predicted increasing trends in the ART treatment, GDM, anaemia, thrombocytopenia, postpartum haemorrhage, congenital malformation, and caesarean section until 2027. Conversely, a decreasing trend was predicted for HDP, PROM, and placental abruption premature, LGA infants, SGA infants, perinatal asphyxia, and stillbirth. Conclusions Maternal and neonatal adverse outcomes became more prevalent from 2010 to 2021 in China. Maternal age and ART treatment were independent risk factors for adverse obstetric outcomes. The findings offered comprehensive trajectories for monitoring pregnancy complications and perinatal outcomes in China, and provided robust intervention targets in obstetric safety. The development of early prediction models and the implementation of prevention efforts for adverse obstetric events are necessary to enhance obstetric safety.

Pal SK, Shekhar C. Association between high-risk fertility behaviour and anaemia among urban Indian women (15-49 years). BMC Public Health 2024; 24:750. [PMID: 38461259 PMCID: PMC10924421 DOI: 10.1186/s12889-024-18254-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2023] [Accepted: 03/01/2024] [Indexed: 03/11/2024] Open
Abstract
BACKGROUND Women in their reproductive age have tremendous health implications that affect their health and well-being. Anaemia is an indicator of inadequate dietary intake and poor health. Maternal malnutrition significantly impacts maternal and child health outcomes, increasing the mother's risk of dying during delivery. High-risk fertility behaviour is a barrier to reducing mother and child mortality. This study aims to examine the level of high-risk fertility behaviour and anaemia among ever-married urban Indian women and also examine the linkages between the both. METHODS Based on the National Family Health Survey's fifth round of data, the study analyzed 44,225 samples of ever-married urban women. Univariate and bivariate analysis and binary logistic regression have been used for the analysis. RESULTS Findings suggested that more than half (55%) of the urban women were anaemic, and about one-fourth (24%) of women had any high-risk fertility behaviour. Furthermore, the results suggest that 20% of women were more vulnerable to anaemia due to high-risk fertility behaviour. For the specific category, 19% and 28% of women were more likely to be anaemic due to single and multiple high-risk fertility. However, after controlling for sociodemographic factors, the findings showed a statistically significant link between high-risk fertility behaviour and anaemia. As a result, 16% of the women were more likely to be anaemic due to high-risk fertility behaviour, and 16% and 24% were more likely to be anaemic due to single and multiple high-risk fertility behaviour, respectively. CONCLUSIONS The findings exposed that maternal high-risk fertility behaviour is a significant factor in raising the chance of anaemia in ever-married urban women of reproductive age in forms of the short birth interval, advanced maternal age, and advanced maternal age & higher order. Policy and choice-based family planning techniques should be employed to minimize the high-risk fertility behaviour among Indian urban women. This might aid in the reduction of the malnutrition status of their children.

Abstract
BACKGROUND In many countries, including China, women are delaying pregnancy until later in life; therefore, hypertensive disorders of pregnancy (HDP) are increasing. This retrospective study from a single center in China aimed to evaluate the association between serum uric acid (SUA) levels and HDP in 288 women of advanced maternal age >35 years. MATERIAL AND METHODS A total of 780 pregnant women of advanced maternal age were included in the study - 288 were had HDP (including gestational hypertension and preeclampsia) and 492 had normal blood pressure using 1: 2 (84: 168) propensity score matching. SUA (collected before 20 weeks' gestation) and HDP incidence in advanced maternal age women were assessed using multivariate logistic modeling and 3 propensity score-based methods. RESULTS Median patient age was 37 years. The risk of developing HDP increases with higher SUA (30.19% vs 13.65%, P<0.001). In the PS-matched cohort, the risk ratio (OR) for HDP with high uric acid after adjusting for confounders was 2.88 (95% CI: 1.44-5.75, P=0.0027). It has been demonstrated that high uric acid is strongly associated with HDP incidence in both the crude population (OR=3.43, 95% CI: 2.01-4.66, P<0.0001) and the weighted cohorts (OR=3.62, 95% CI: 2.81-4.66, P<0.0001). As a successive variable, after adjusting for the clinical confounders, a 1-SD increase in SUA was related to a 135% increased risk of HDP (OR=2.35; 95% CI: 1.57-3.50; P<0.0001) based on the fully adjusted model. There were similar conclusions in the sensitivity analysis. CONCLUSIONS There was a significant association between SUA and HDP in women of advanced maternal age, supporting the importance of early detection of SUA in pregnant women.

Abstract
Worldwide, pregnancy at age 35 or older, termed 'advanced maternal age (AMA)', is increasing exponentially. As the incidence of pregnancy at AMA has increased, a growing body of evidence has suggested that AMA is also associated with increased risk for adverse maternal and fetal outcomes outside of genetic anomalies. Importantly, despite the mounting evidence and the increased global risk of adverse perinatal outcomes observed, few studies have examined the potential mechanisms underlying this elevated risk in pregnant people ≥35 years of age. Wooldridge and colleagues begin to address this gap in the literature. In their recent report, they examine vessel stiffness in omental resistance vessels obtained from pregnant individuals ≥35 years of age compared with pregnant individuals <35 years of age. Omental arteries were isolated and assessed via pressure myography (mechanical properties) and histological analysis for collagen and elastin content. Overall, the findings from this investigation report that maternal resistance arteries collected from women of AMA were less compliant and had less elastin than arteries obtained from women <35 years of age, suggesting that maternal resistance vessel stiffening in AMA may contribute to increased risk of adverse pregnancy outcomes. The authors should be commended for completing these studies in human resistance vessels, which now open new avenues for investigation and provoke a cascade of questions related to maternal cardiovascular adaptations to pregnancy in women ≥35 years of age.

Abstract
BACKGROUND Infant mortality persists as a global public health concern, particularly in lower-middle-income countries (LIMCs) such as Nigeria. The risk of an infant dying before one year of age is estimated to be six times higher in Africa than in Europe. Nigeria recorded an infant mortality rate of 72.2 deaths per 1,000 live births in 2020, in contrast to the global estimate of 27.4 per 1,000 live births. Several studies have been undertaken to determine the factors influencing infant mortality. OBJECTIVE This scoping review sought to identify and summarise the breadth of evidence available on factors associated with infant mortality in Nigeria. METHODS This review followed the five-stage principles of Arksey and O'Malley's framework. Four electronic databases were searched with no limit to publication date or study type: Ovid MEDLINE, PubMed, CINAHL Complete, and Web of Science. Selected studies were imported into Endnote software and then exported to Rayyan software where duplicates were removed. Included articles were thematically analysed and synthesised using the socioecological model. RESULTS A total of 8,139 references were compiled and screened. Forty-eight articles were included in the final review. At the individual level, maternal- and child-related factors were revealed to influence infant mortality; socioeconomic and sociocultural factors at the interpersonal level; provision and utilisation of health services, health workforce, hospital resources and access to health services at the organisational level; housing/neighbourhood and environmental factors at the community level; and lastly, governmental factors were found to affect infant mortality at the public policy level. CONCLUSION Factors related to the individual, interpersonal, organisational, community and public policy levels were associated with infant mortality in Nigeria.

Abstract
BACKGROUND Stroke during pregnancy is rare, occurring in 30 of 100,000 pregnancies and accounting for 7% of maternal deaths in the United States from 2016 to 2018. Metabolic and bariatric surgery (MBS) has been shown to reduce symptoms of chronic conditions that are risk factors for stroke, including hypertension, hypercholesterolemia, and diabetes in women. However, little is known about the impact of MBS on stroke risk during pregnancy. OBJECTIVES To examine stroke and stroke risk factors including preeclampsia, eclampsia, gestational hypertension, and embolism/thrombosis in women of reproductive age who have had MBS. SETTING We used the National Inpatient Sample, a publicly available data set from the Healthcare Cost and Utilization Project that samples 20% of hospital discharges in the United States. METHODS This cross-sectional study included women between the ages of 20 and 44 years who had a maternal admission code. Weighted logistic regression was conducted to assess the odds of stroke and stroke risk factors in women with a history of MBS compared with other women of reproductive age. RESULTS Women with a history of MBS have 12% lower adjusted odds of developing preeclampsia/eclampsia and 10% lower adjusted odds of gestational hypertension than women who did not undergo MBS. When stratified by race, the difference was significant in White women (preeclampsia/eclampsia: adjusted odds ratio [aOR] = .89; 95% confidence interval [CI], .81-.98; gestational hypertension: aOR = .91; 95% CI, .83-1.00). Latinas with MBS had significantly lower odds of preeclampsia/eclampsia (aOR = .75; 95% CI, .64-.90). CONCLUSIONS MBS helps women lose weight and decrease the incidence of some pregnancy-related risk factors for stroke. However, there is a notable racial health disparity.

Abstract
Background Women in advanced maternal age (older than 35 years of age) are at higher risk of obstetric complications and adverse perinatal outcomes than younger women. Objective To know the maternal and perinatal morbidities associated to advanced age in pregnant women. Material and methods Analytical cross-sectional study. Women with resolution of pregnancy in the medical unit were included and distributed in two groups: group 1, advanced age, ≥ 35 years, and group 2, < 35 years. Clinical data, maternal and perinatal morbidities of the newborn (NB) were collected from the medical record. Results We included 240 patients, 120 per group; a significant association of advanced maternal age with maternal morbidities such as diseases prior to pregnancy was demonstrated (p < 0.0001), including diabetes mellitus during pregnancy (p = 0.002), hypertensive disease of pregnancy (p = 0.0001), pregnancy resolution by cesarean section (p = 0.04), obstetric hemorrhage (p = 0.0002), prenatal control with < 5 consultations (p = 0.008), as well as those with perinatal morbidities of the NB: preterm gestational age (p = 0.001), intrauterine growth retardation (p = 0.01), low weight for gestational age (p = 0.001) and admission of the NB to the neonatal intensive care unit (p = 0.007); with multivariate analysis, an association of advanced maternal age with diabetes mellitus, hypertensive disease of pregnancy and obstetric hemorrhage was observed (R2 = 0.9884; p < 0.0001). Conclusion The maternal and perinatal morbidities are associated with advanced age in pregnant women.

Abstract
Introduction Despite a notable reduction in infant mortality over recent decades, the United States, with a rate of 5.8 deaths per 1,000 live births, still ranks unfavorably compared to other developed countries. This improvement appears inadequate when contrasted with the country's healthcare spending, the highest among developed nations. A significant proportion of this infant mortality rate can be attributed to neonatal fatalities. Objective The present study aimed to determine the risk factors associated with neonatal deaths in the United States. Method Using the United States Vital Statistics records, we conducted a retrospective study on childbirths between 2015 and 2019 to identify risk factors for neonatal mortality. Our final multivariate analysis included maternal parameters like age, insurance type, education level, cesarean section rate, pregnancy inductions and augmentations, weight gain during pregnancy, birth weight, number of prenatal visits, pre-existing conditions like chronic hypertension and prediabetes, and pregnancy complications like gestational diabetes mellitus (GDM). These variables were incorporated to enhance our model's sensitivity and specificity. Result There were 51,174 neonatal mortalities. Mothers with augmentation of labor had a 25% reduction in neonatal mortalities (NM) (OR=0.75; 95% CI 0.72-0.79), while labor induction was associated with a 31% reduction in NM (OR=0.69; 95% CI 0.66-0.72). Women above 40 years had a 29% increase in NM rate (OR=1.29;95% CI 1.15-1.44). Women without prenatal care have a 22% increase in the risk of NM (OR=1.22; 95% CI 1.14-1.30). The present model has a 60.7% sensitivity and a 99.9% specificity. Conclusion In the present study, significant interventions such as labor induction, augmentation, and prenatal care were associated with improved neonatal outcomes. These findings could serve as an algorithm for improving neonatal outcomes in the United States.

[PMID: 36923848 PMCID: PMC10009682 DOI: 10.1016/j.heliyon.2023.e13848] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2022] [Revised: 02/10/2023] [Accepted: 02/13/2023] [Indexed: 02/27/2023] Open
Abstract
Bangladesh, a lower-middle-income country in South Asia, has achieved a significant reduction in child mortality over the last three decades from 151 to 40 per 1000 live births. However, child mortality is still considered high, which may be attributed to a lack of awareness among mothers regarding the risk factors, particularly their perceptions of intimate partner violence (IPV). To investigate the effect of demographic and socioeconomic factors of women on child mortality, this study extracted data from the cross-sectional survey of Bangladesh Multiple Indicator Cluster Survey (MICS) 2019. The data were analyzed using a Poisson regression model to assess women's perceptions and exposure to physical violence in the last three years preceding the survey and their impact on the risk of child mortality. The results indicated that approximately 26% of the participants justified domestic violence under certain circumstances. Moreover, the prevalence of child mortality was higher among those who thought that IPV is acceptable than among those who considered such violence to be unjustified. Among women who are strongly averse to partner violence, the risk of child mortality was significantly lower in those who had higher levels of education, higher household income, internet usage experience, first child at 20 years or later, frequent access to mass media, and one or two children ever born. Moreover, child mortality rates also varied across geographical areas, with children from Sylhet and Mymenshing being the most vulnerable. The data indicates women's intolerable attitudes toward partner violence not only improve their status but also increase the survival chances of their young children.

Gudayu TW. Epidemiology of neonatal mortality: a spatial and multilevel analysis of the 2019 mini-Ethiopian demographic and health survey data. BMC Pediatr 2023; 23:26. [PMID: 36647037 PMCID: PMC9843859 DOI: 10.1186/s12887-023-03838-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/29/2022] [Accepted: 01/06/2023] [Indexed: 01/18/2023] Open
Abstract
BACKGROUND Sub-Saharan African countries are a high-burden region of neonatal mortality and showed slow progress in its reduction. In developing countries, as long as the current trend of mortality persists, achieving a sustainable development target for neonatal mortality would be challenging. The aim of this study was to detect significant geographic areas and identify community and individual-level predictors of neonatal mortality in Ethiopia to draw attention to a policy. METHODS A weighted total sample of 24,136 mothers from the 2019 mini-Ethiopian demographic and health survey data were included in the analysis. Global Moran's I statistics was run to check the clustering of neonatal mortality and then kriging interpolation was done to predict the magnitude of neonatal mortality in Ethiopia. In addition, SaTScan analysis was also executed to identify hot spot clusters of neonatal mortality. Finally, a multilevel mixed-effect logistic regression model was used to identify community and individual-level predictors of early neonatal and neonatal mortality. RESULTS The lifetime early neonatal and neonatal mortality among mothers in Ethiopia was 5.08 (95% CI: 4.13-6.03) and 6.54 (5.55, 7.52) per 1000 births respectively. Neonatal mortality was spatially clustered in the country and the SaTScan analysis identified significant hotspot areas of neonatal mortality in the Amhara and Afar regions and some areas of the Somali and Oromia regions. Its predicted magnitude was > 8 per 1000 births in wide areas of the Amhara and Benishangul regions. A multilevel mixed-effect logistics regression analysis identified that a lower level of maternal education, being a twin neonate, and being a male neonate were predictors of both early neonatal and neonatal mortality. Whereas, the younger age of mothers predicted neonatal mortality. CONCLUSIONS Neonatal mortality in Ethiopia is geographically clustered and sociodemographic and obstetric factors played a significant role. Policy direction should focus on evidence-based practices like midwives-led community and facility-based continuum of care from preconception to postnatal periods to possibly reduce neonatal mortality.

Women's education, contraception use, and high-risk fertility behavior: A cross-sectional analysis of the demographic and health survey in Ethiopia. Front Glob Womens Health 2023; 4:1071461. [PMID: 36937044 PMCID: PMC10014881 DOI: 10.3389/fgwh.2023.1071461] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2022] [Accepted: 02/10/2023] [Indexed: 03/05/2023] Open
Abstract
Background High-risk fertility behavior (HRFB) among women is the main factor in a wide range of detrimental effects on both the mother's and the child's health, which has an impact on both the mother's and the child's survival. Early childbearing is associated with a higher number of live births and may result in poorer maternal, baby, and child health outcomes. Infant and child mortality are also linked to short birth intervals and higher birth order. Thus, this study aims to examine the link between women's education, contraception use, and high-risk fertility behavior in Ethiopia. Methods Data was drawn from the 2019 Ethiopian Interim Demographic and Health Survey. The analysis covered a total of 5,846 women. The effect of predictor variables on HRFB was quantified using multivariable logistic regression analysis. At a 95% CI of the odds ratio excluding one, a significant association between the HRFB and predictor variables was observed. Results About 72.8% (95% CI 71.6%-73.9%) of women experience high-risk fertility behaviors. Of these, 32% experience single high-risk fertility behavior, and 40.8% experience multiple high-risk fertility behaviors. Of those who experience high-risk fertility behaviors, 58.7% have birth orders of more than three, 22.4% have short birth intervals (less than 24 months); 35.1% are old (over 34 years old); and 1.6% are young (less than 18 years old). Women with no education (AOR = 4.31; 95% CI: 2.09, 8.89) and primary education only (2.71; AOR = 2.71; 95% CI: 1.63, 4.50) are more likely to engage in high-risk fertility behaviors than women with a higher level of education. Every additional year of schooling reduces the odds of high-risk fertility behavior by 6% (AOR = 0.94; 95% CI: 0.89, 0.98). The use of modern contraception (AOR = 0.74; 95% CI: 0.622, 0.879) and knowledge of modern contraception methods (AOR = 0.80; 95% CI: 0.66, 0.96) reduce the risk of HRFB. Conclusions Primary education and a lack of education significantly raise the risk of HRFB. However, in Ethiopia, the risk of experiencing HRFB is reduced through modern contraceptive methods, awareness of modern contraceptive methods, and years of education. All initiatives to decrease maternal and newborn mortalities by reducing the risk of HRFB should educate women and encourage them to use modern contraception.

Abstract
Objective To explore the effect of the family-centered empowerment model (FECM) on reducing anxiety, improving care ability, and readiness for hospital discharge of main caregivers of preterm infants. Methods The primary caregivers of preterm infants who were admitted to the Neonatal intensive care Unit (NICU) of our center from September 2021 to April 2022 were selected as the research objects. According to the wishes of the primary caregivers of preterm infants, they were divided into group A (FECM group) and group B (non-FECM group). The intervention effects were evaluated with the Anxiety Screening Scale (GAD-7), the Readiness for Hospital Discharge Scale-Parent Version (RHDS-Parent Form), and the Primary Caregivers of Premature Infants Assessment of Care Ability Questionnaire. Results Before the intervention, there was no statistically significant difference in the general information, anxiety screening, the scores of each dimension, and total score of the comprehensive ability of the main caregivers, and the score of caregiver preparedness between the two groups (P > 0.05). After the intervention, there were statistically significant differences in the anxiety screening, the total score and total score of each dimension of the care ability, and the score of caregiver preparedness between the two groups (P < 0.05). Conclusions FECM can effectively reduce the anxiety of primary caregivers of premature infants and improve their readiness for hospital discharge and care ability. To improve the quality of life of premature infants by implementing personalized training, care guidance, and peer support.

Abstract
Several studies have shown that children from pregnancies with estimated first-trimester risk based on fetal nuchal translucency thickness and abnormal maternal serum pregnancy protein and hormone levels maintain a higher likelihood of adverse outcomes, even if initial testing for known genetic conditions is negative. We used the Finnish InTraUterine cohort (ITU), which is a comprehensively characterized perinatal cohort consisting of 943 mothers and their babies followed throughout pregnancy and 18 months postnatally, including mothers shortlisted for prenatal genetic testing but cleared for major aneuploidies (cases: n = 544, 57.7%) and control pregnancies (n = 399, 42.3%). Using genome-wide genotyping and RNA sequencing of first-trimester and term placental tissue, combined with medical information from registry data and maternal self-report data, we investigated potential negative medical outcomes and genetic susceptibility to disease and their correlates in placenta gene expression. Case mothers did not present with higher levels of depression, perceived stress, or anxiety during pregnancy. Case children were significantly diagnosed more often with congenital malformations of the circulatory system (4.12 (95% CI [1.22−13.93]) higher hazard) and presented with significantly more copy number duplications as compared to controls (burden analysis, based on all copy number variants (CNVs) with at most 10% frequency, 823 called duplications in 297 cases versus 626 called duplications in 277 controls, p = 0.01). Fifteen genes showed differential gene expression (FDR < 0.1) in association with congenital malformations in first-trimester but not term placenta. These were significantly enriched for genes associated with placental dysfunction. In spite of normal routine follow-up prenatal testing results in early pregnancy, case children presented with an increased likelihood of negative outcomes, which should prompt vigilance in follow-up during pregnancy and after birth.

Abstract
BACKGROUND The number of women delivering at advanced maternal age (AMA; > = 35) continuously increases in developed and high-income countries. Large cohort studies have associated AMA with increased risks of various pregnancy complications and adverse pregnancy outcomes, which raises great concerns about the adverse effect of AMA on the long-term health of offspring. Specific acquired characteristics of parents can be passed on to descendants through certain molecular mechanisms, yet the underlying connection between AMA-related alterations in parents and that in offspring remains largely uncharted. METHODS We profiled the DNA methylomes of paired parental peripheral bloods and cord bloods from 20 nuclear families, including 10 AMA and 10 Young, and additional transcriptomes of 10 paired maternal peripheral bloods and cord bloods. RESULTS We revealed that AMA induced aging-like changes in DNA methylome and gene expression in both parents and offspring. The expression changes in several genes, such as SLC28A3, were highly relevant to the disorder in DNA methylation. In addition, AMA-related differentially methylated regions (DMRs) identified in mother and offspring groups showed remarkable similarities in both genomic locations and biological functions, mainly involving neuron differentiation, metabolism, and histone modification pathways. AMA-related differentially expressed genes (DEGs) shared by mother and offspring groups were highly enriched in the processes of immune cell activation and mitotic nuclear division. We further uncovered developmental-dependent dynamics for the DNA methylation of intergenerationally correlated DMRs during pre-implantation embryonic development, as well as diverse gene expression patterns during gametogenesis and early embryonic development for those common AMA-related DEGs presenting intergenerational correlation, such as CD24. Moreover, some intergenerational DEGs, typified by HTRA3, also showed the same significant alterations in AMA MII oocyte or blastocyst. CONCLUSIONS Our results reveal potential intergenerational inheritance of both AMA-related DNA methylome and transcriptome and provide new insights to understand health problems in AMA offspring.

Impact of maternal age on neonatal outcomes among very preterm infants admitted to Chinese neonatal intensive care units: a multi-center cohort study. Transl Pediatr 2022; 11:1130-1139. [PMID: 35957998 PMCID: PMC9360824 DOI: 10.21037/tp-22-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/01/2022] [Accepted: 04/27/2022] [Indexed: 11/24/2022] Open
Abstract
BACKGROUND The percentage of advanced maternal age (aged over 35 years) mothers has been rising across the world, the evidence of maternal age on neonatal outcomes from low- and middle-income countries is scarce. Our objective was to evaluate the effect of maternal age on mortality and major morbidity among very preterm infants admitted to Chinese neonatal intensive care units. METHODS Data from a retrospective multi-center cohort of all complete care very preterm infants admitted to 57 neonatal intensive care units that participated in the Chinese Neonatal Network from January 1st to December 31st, 2019 were analyzed. Neonatal outcomes including mortality or any major morbidity, defined as necrotizing enterocolitis stage 2 or 3, moderate & severe bronchopulmonary dysplasia, severe intraventricular hemorrhage, cystic periventricular leukomalacia, severe retinopathy of prematurity, or sepsis. A multiple logistic regression model was constructed to analyze the independent association between maternal age and neonatal outcome. RESULTS Among 7,698 eligible newborns, 80.5% of very preterm infants were born to mothers between the ages of 21 and 35 years, with 18.0% born to mothers >35 years and 1.5% born to mothers <21 years. Higher rates of maternal hypertension, maternal diabetes, cesarean deliveries, antenatal steroid usage were noted as maternal age increased. The proportion of prenatal care, cesarean section, antenatal steroid usage and inborn for very preterm infants born to mothers <21 years was lower than those of mothers of other ages. Compared to the ages of 21-35 years group, the odds of severe intraventricular hemorrhage (adjusted odd ratio: 2.00, 95% CI: 1.08-3.71) was significantly higher in the ages of 15-20 years group. Increasing maternal age was associated with higher rates of small for gestational age and lower birth weight of very preterm infants, but no correlation between advanced maternal age and very preterm infants mortality or major morbidity. CONCLUSIONS Among very preterm infants, increasing maternal age was associated with higher rates of small for gestational age but not neonatal mortality or major morbidity. Young maternal age may increase the risk of severe intraventricular hemorrhage of very preterm infants.

Abstract
The aim of this study was to analyze the trends in diabetes in pregnancy in Belgrade, Serbia for the period of the past decade and forecast the number of women with pre-gestational diabetes for the years 2030 and 2050. The study included the data on all pregnant women with diabetes from the registry of the deliveries in Belgrade, by the City Institute of Public Health of Belgrade, Serbia for the period between 2010 and 2020 and the published data on the deliveries on the territory of Belgrade. During the examined period the total number of live births in Belgrade was 196,987, and the prevalence of diabetes in pregnancy was 3.4%, with the total prevalence of pre-gestational diabetes of 0.7% and overall prevalence of GDM of 2.7%. The average age of women in our study was significantly lower in 2010 compared to 2020. The forecasted prevalence of pre-gestational diabetes among all pregnant women for 2030 is 2% and 4% for 2050 in our cohort. Our study showed that the prevalence of pre-gestational diabetes has increased both among all pregnant women and among women with diabetes in pregnancy in the past decade in Belgrade, Serbia and that it is expected to increase further in the next decades and to further double by 2050.

Zhang H, Wang W. Risk factors and adverse pregnancy outcomes in older pregnant women with hypertensive disorders of pregnancy. J Obstet Gynaecol Res 2022; 48:1710-1720. [PMID: 35596590 DOI: 10.1111/jog.15295] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2021] [Revised: 04/02/2022] [Accepted: 05/06/2022] [Indexed: 11/30/2022]
Abstract
BACKGROUND To assess the independent risk factors and pregnancy outcomes of hypertensive disorders of pregnancy (HDPs) in Chinese advanced age pregnancy women. DESIGN Secondary analysis of international published data. MATERIALS AND METHODS PubMed, Web of Science, Scopus, Embase, Cochrane library, and Chinese databases from inception to February 23, 2022 were searched to identify eligible studies. Meta-analysis was conducted to provide meaningful summative outcomes. The quality evaluation of included study was performed. The analyses were done with Review Manager 5.3 and Stata 14.0 software. RESULTS Totally, 13 eligible articles were included, among which 3 articles investigated the risk factors, 6 articles studied pregnancy outcomes, and 4 articles examined both risk factors and pregnancy outcomes. Chinese older pregnant women with the HDPs had high pooled incidences of abnormal body mass index, maternal education, family history of hypertension, history of chronic hypertension, gestational diabetes, irregular delivery inspection, psychosocial factors, and primiparity compared to those without HDPs. The incidence of cesarean delivery, placental abruption, premature rupture of membranes, postpartum hemorrhage, preterm birth, fetal asphyxia, fetal distress, fetal growth restriction, and low birth weight in Chinese older pregnant women with HPDs were significantly higher than those without HDPs. CONCLUSION This study identified several possible risk factors which promoted the onset of HDPs in Chinese older pregnant women, and HDPs significantly increases risk of adverse pregnancy outcomes (APOs). Further research is needed to take targeted measures to prevent HDPs and explore efficient management methods to minimize the risk of APOs associated with HDPs in Chinese older pregnant women.

Abstract
INTRODUCTION Several studies have reported on the maternal age-associated risks of congenital anomalies. However, there is a paucity of studies with comprehensive review of anomalies. We aimed to quantify the risk of birth defects in children born to middle-aged mothers compared with that in children born to young or older mothers. MATERIAL AND METHODS We classified maternal ages into three groups: young (<20 years old), middle (20-34 years old) and older age (≥35 years old). Observational studies that met our age criteria were eligible for inclusion. The articles searched using the Embase and MEDLINE databases were those published from 1989 to January 21, 2021. The Newcastle-Ottawa scale was used to assess the risk of bias. If heterogeneity exceeded 50%, the random effect method was used; otherwise, the fixed-effect method was used. Prospero registration number: CRD42021235229. RESULTS We included 15 cohort, 14 case-control and 36 cross-sectional studies. The pooled unadjusted odds ratio (95% CI) of any congenital anomaly was 1.64 (1.40-1.92) and 1.05 (0.95-1.15) in the older and young age groups, respectively (very low quality of evidence). The pooled unadjusted odds ratio of chromosomal anomaly was 5.64 (5.13-6.20) and 0.69 (0.54-0.88) in the older and young age groups, respectively. The pooled unadjusted odds ratio of non-chromosomal anomaly was 1.09 (1.01-1.17) and 1.10 (1.01-1.21) in the older and young age groups, respectively (very low quality of evidence). The incidence of abdominal wall defects was increased in children of women in the young maternal age group. CONCLUSIONS We identified that very low quality evidence suggests that women in the older maternal age group had increased odds of having children with congenital anomalies compared with those in the 20-34 year age group. There was no increase in odds of children with congenital anomalies in women of <20 year age group except for abdominal defects compared with those in the 20-34 year age group. The results stem from very low quality evidence with no adjustment of confounders.

Abstract
OBJECTIVE To evaluate whether advanced maternal age (35-39 years, AMA)/very advanced maternal age (≥40 years, VAMA) impacts neonatal outcomes of very-low-birth-weight (VLBW) infants. METHODS Data of VLBW infants admitted to our unit were reviewed. Demographic findings and neonatal outcomes were compared among maternal age [(<35 years, not advanced maternal age, n = 329), AMA (n = 209), and VAMA (n = 43)] groups. Univariate and multivariate analyses were performed to identify the associated risk factors for neonatal outcomes. RESULT Mortality and overall morbidities showed no significant intergroup differences, except for massive pulmonary hemorrhage (MPH). Multivariate analysis revealed that AMA/VAMA was not significantly associated with MPH development, while ≥ two doses of surfactant administration was. Higher gestational age and antenatal corticosteroid administration were protective. CONCLUSION AMA/VAMA is not associated with neonatal mortality and morbidities. Since the proportion of AMA/VAMA mothers is expected to increase, perinatal medicine practitioners should focus on approaches before and immediately after birth of such infants.

Abstract
The human gut microbiome harbors a diverse range of microbes that play a fundamental role in the health and well-being of their host. The early-life microbiome has a major influence on human development and long-term health. Perinatal factors such as maternal nutrition, antibiotic use, gestational age and mode of delivery influence the initial colonization, development, and function of the neonatal gut microbiome. The perturbed early-life gut microbiome predisposes infants to diseases in early and later life. Understanding how perinatal factors guide and shape the composition of the early-life microbiome is essential to improving infant health. The following review provides a synopsis of perinatal factors with the most decisive influences on initial microbial colonization of the infant gut.

Abstract
Bifidobacterium bifidum OLB6378 (OLB6378) was selected as a strain that
enhances the production of secretory immunoglobulin A (IgA) in vitro.
This ability of non-live OLB6378 has been shown by a clinical trial in preterm infants. In
the present study, we examined whether non-live OLB6378 also enhances the production of
secretory IgA, even in full-term infants. One hundred full-term infants were allocated to
receive formula with (BbF group, 49 infants) or without non-live OLB6378 (PF group, 51
infants). Breastfeeding was prioritised, so infant formula was used for infants with
breastfeeding difficulties. The intervention was initiated by five days of age. The faecal
IgA concentration and OLB6378 level were determined at one, two, four, and eight weeks of
age. Faecal IgA in the BbF group (1.04 ± 0.47 mg/g of faeces, n=45) was significantly
higher than that in the PF group (0.85 ± 0.42 mg/g of faeces, n=49) at four weeks of age
(p=0.047). OLB6378 was not detected in faeces at any age. This indicated that production
of secretory IgA in full-term infants may also be enhanced by non-live OLB6378 intake.

Abstract
Early identification of high-risk pregnancies can reduce global neonatal mortality rate. Using the most recent Demographic and Health Surveys from 56 low- and middle-income countries, we examined the proportion of mothers with history of neonatal deaths. Logistic regression models were used to assess the association between maternal history of neonatal death and subsequent neonatal mortality. The adjusted models controlled for socioeconomic, child, and pregnancy-related factors. Country-specific analyses were performed to assess heterogeneity in this association across countries. Among the 437,049 live births included in the study, 6910 resulted in neonatal deaths. In general, 22.4% (1549) occurred to mothers with previous history of neonatal death; at the country-level, this proportion ranged from 1.2% (95% confidence interval [CI] 0.0, 2.6) in Dominican Republic to 38.1% (95% CI 26.0, 50.1) in Niger. Maternal history of neonatal death was significantly associated with subsequent neonatal death in both the pooled and the subgroup analyses. In the fully adjusted model, history of neonatal death was associated with 2.1 (95% CI 1.9, 2.4) times higher odds of subsequent neonatal mortality in the pooled analysis. We observed large variation in the associations across countries ranging from fully adjusted odds ratio (FAOR) of 0.4 (95% CI 0.0, 4.0) in Dominican Republic to 16.1 (95% CI 3.6, 42.0) in South Africa. Our study suggests that maternal history of neonatal death could be an effective early identifier of high-risk pregnancies in resource-poor countries. However, country-specific contexts must be considered in national policy discussions.

Abstract
OBJECTIVES This study aimed at examining the association between young maternal age at first childbirth and under-5 mortality in sub-Saharan Africa (SSA). DESIGN AND SETTING This cross-sectional study pooled nationally-representative data from the most recent Demographic and Health Surveys conducted in 30 countries in SSA from 2010 to 2019. PARTICIPANTS 116 379 mothers of children under 5. RESULTS The prevalence of adolescent childbirth and death in children under 5 in SSA were 57.36% (95% CI 53.73% to 60.99%) and 4.10% (95% CI 3.65% to 4.54%), respectively. Children born to mothers whose first childbirth occurred at <20 years were 11% more likely to die before the age of 5 compared with those whose mothers' first childbirth occurred at age ≥20 years (adjusted odds ratio (aOR) 1.11; 95% CI 1.05 to 1.18). In terms of the covariates, the likelihood of under-5 mortality was higher among children born to single (aOR 1.54; 95% CI 1.41 to 1.67) and cohabiting mothers (aOR 1.10; 95% CI 1.01 to 1.21) compared with married mothers. Children born to mothers who were obese were more likely to die before the age of 5 compared with those born to mothers with normal body weight (aOR 1.17; 95% CI 1.09 to 1.26). The odds of under-5 mortality were higher among children whose weight at birth was <2500 g compared with those whose weight was ≥2500 g at birth (aOR 1.83; 95% CI 1.64 to 2.03). CONCLUSIONS The findings call for the need to enhance policies aimed at reducing under-5 mortality in SSA by reducing adolescent pregnancy and childbirth through family planning, comprehensive sexuality education, and the elimination of child marriage. Again, Since under-5 mortality among adolescent mothers is linked with their poor socio-economic status, there is the need for government and non-governmental organisations in SSA to introduce poverty alleviation programmes and improve access to both formal and informal education as a way of enhancing the socioeconomic status of adolescent mothers. Public health education, through continuous advocacy programmes should be done to encourage adolescent mothers to access antenatal care and health facility deliveries as a way of enhancing the survival status of their children. These interventions should be implemented, taking into consideration other characteristics of mothers such marital status and BMI and child's characteristics such as child's weight, which were found to be associated with high under-5 mortality.
