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.

[PMID: 37500755 PMCID: PMC10899098 DOI: 10.1038/s41390-023-02713-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2023] [Revised: 04/25/2023] [Accepted: 06/15/2023] [Indexed: 07/29/2023]
Abstract
BACKGROUND Very preterm infants are at elevated risk for neurodevelopmental delays. Earlier prediction of delays allows timelier intervention and improved outcomes. Machine learning (ML) was used to predict mental and psychomotor delay at 25 months. METHODS We applied RandomForest classifier to data from 1109 very preterm infants recruited over 20 years. ML selected key predictors from 52 perinatal and 16 longitudinal variables (1-22 mo assessments). SHapley Additive exPlanations provided model interpretability. RESULTS Balanced accuracy with perinatal variables was 62%/61% (mental/psychomotor). Top predictors of mental and psychomotor delay overlapped and included: birth year, days in hospital, antenatal MgSO4, days intubated, birth weight, abnormal cranial ultrasound, gestational age, mom's age and education, and intrauterine growth restriction. Highest balanced accuracy was achieved with 19-month follow-up scores and perinatal variables (72%/73%). CONCLUSIONS Combining perinatal and longitudinal data, ML modeling predicted 24 month mental/psychomotor delay in very preterm infants ½ year early, allowing intervention to start that much sooner. Modeling using only perinatal features fell short of clinical application. Birth year's importance reflected a linear decline in predicting delay as birth year became more recent. IMPACT Combining perinatal and longitudinal data, ML modeling was able to predict 24 month mental/psychomotor delay in very preterm infants ½ year early (25% of their lives) potentially advancing implementation of intervention services. Although cognitive/verbal and fine/gross motor delays require separate interventions, in very preterm infants there is substantial overlap in the risk factors that can be used to predict these delays. Birth year has an important effect on ML prediction of delay in very preterm infants, with those born more recently (1989-2009) being increasing less likely to be delayed, perhaps reflecting advances in medical practice.

[PMID: 38206626 PMCID: PMC10784860 DOI: 10.1001/jamanetworkopen.2023.51166] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Accepted: 11/20/2023] [Indexed: 01/12/2024] Open
Abstract
Importance Lower educational attainment is associated with increased risk of adverse pregnancy outcomes, but it is unclear which pathways mediate this association. Objective To investigate the association between educational attainment and pregnancy outcomes and the proportion of this association that is mediated through modifiable cardiometabolic risk factors. Design, Setting, and Participants In this 2-sample mendelian randomization (MR) cohort study, uncorrelated (R2 < 0.01) single-nucleotide variants (formerly single-nucleotide polymorphisms) associated with the exposure (P < 5 × 10-8) and mediators and genetic associations with the pregnancy outcomes from genome-wide association studies were extracted. All participants were of European ancestry and were largely from Finland, Iceland, the United Kingdom, or the US. The inverse variance-weighted method was used in the main analysis, and the weighted median, weighted mode, and MR Egger regression were used in sensitivity analyses. In mediation analyses, the direct effect of educational attainment estimated in multivariable MR was compared with the total effect estimated in the main univariable MR analysis. Data were extracted between December 1, 2022, and April 30, 2023. Exposure Genetically estimated educational attainment. The mediators considered were genetically estimated type 2 diabetes, body mass index, smoking, high-density lipoprotein cholesterol level, and systolic blood pressure. Main Outcomes and Measures Ectopic pregnancy, hyperemesis gravidarum, gestational diabetes, preeclampsia, preterm birth, and offspring birth weight. Results The analyses included 3 037 499 individuals with data on educational attainment, and those included in studies on pregnancy outcomes ranged from 141 014 for ectopic pregnancy to 270 002 with data on offspring birth weight. Each SD increase in genetically estimated educational attainment (ie, 3.4 years) was associated with an increased birth weight of 42 (95% CI, 28-56) g and an odds ratio ranging from 0.53 (95% CI, 0.46-0.60) for ectopic pregnancy to 0.81 (95% CI, 0.71-0.93) for preeclampsia. The combined proportion of the association that was mediated by the 5 cardiometabolic risk factors ranged from -17% (95% CI, -46% to 26%) for hyperemesis gravidarum to 78% (95% CI, 10%-208%) for preeclampsia. Sensitivity analyses accounting for pleiotropy were consistent with the main analyses. Conclusions and Relevance In this MR cohort study, intervening for type 2 diabetes, body mass index, smoking, high-density lipoprotein cholesterol level, and systolic blood pressure may lead to reductions in several adverse pregnancy outcomes associated with lower levels of education. Such public health interventions would serve to reduce health disparities attributable to social inequalities.

Associations between socio-demographic characteristics of pregnant women and birth outcome: The Nutritional status of Expectant Mothers and their newborn Infants study. Child Care Health Dev 2024; 50:e13181. [PMID: 37737654 DOI: 10.1111/cch.13181] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/23/2023] [Revised: 08/30/2023] [Accepted: 09/10/2023] [Indexed: 09/23/2023]
Abstract
BACKGROUND Low socio-economic status is associated with poor birth outcomes, however, few studies on this topic have been conducted in South Africa. We determined associations between socio-demographic variables of pregnant women and birth outcome in their offspring. METHODS This study was nested in a prospective cohort study conducted at an antenatal clinic at a regional hospital in Bloemfontein, South Africa. Questionnaires on socio-demographic information were completed on 682 pregnant women in a structured interview. Post-delivery, 331 participants provided the Road to Health Booklets for 347 infants, in which birth data were recorded. Associations between socio-demographic variables and birth outcome (defined as premature delivery or low length-for-age or low weight-for-length at birth) were investigated. Logistic regression with backward selection (p < 0.05) was used to select independent factors that were significantly associated with birth outcome. Variables with a p-value of <0.15 on bivariate analysis were considered for inclusion in the model. RESULTS Poor birth outcome was observed in 36.3% (116/320) of women. The odds of experiencing poor birth outcome were lower for women who owned a stove versus those who did not (OR 0.11, 95% CI: 0.02-0.67), and higher for women with grade 8-10 (OR 5.84, 95% CI: 1.90-17.91) or grade 10-12 (OR 4.33, 95% CI: 1.50-12.49) as their highest level of education versus tertiary education. The odds of experiencing poor birth outcomes were also higher for those employed part-time (OR 2.55, 95% CI: 1.10-5.93) versus full-time and/or self-employed. CONCLUSION Our findings confirm that the presence of basic amenities such as a stove, better education and employment improve the chances of better birth outcomes. Early screening of pregnant women for the identification of socio-demographic risk factors that may impact on birth outcome is recommended.

Abstract
Importance Inequalities in preterm infant mortality exist between population subgroups within the United States. Objective To characterize trends in preterm infant mortality by maternal race and socioeconomic status to assess how inequalities in preterm mortality rates have changed over time. Design, Setting, and Participants This was a retrospective longitudinal descriptive study using the US National Center for Health Statistics birth infant/death data set for 12 256 303 preterm infant births over 26 years, between 1995 and 2020. Data were analyzed from December 2022 to March 2023. Exposures Maternal characteristics including race, smoking status, educational attainment, antenatal care, and insurance status were used as reported on an infant's US birth certificate. Main Outcomes and Measures Preterm infant mortality rate was calculated for each year from 1995 to 2020 for all subgroups, with a trend regression coefficient calculated to describe the rate of change in preterm mortality. Results The average US preterm infant mortality rate (IMR) decreased from 33.71 (95% CI, 33.71 to 34.04) per 1000 preterm births per year between 1995-1997, to 23.32 (95% CI, 23.05 to 23.58) between 2018-2020. Black non-Hispanic infants were more likely to die following preterm births than White non-Hispanic infants (IMR, 31.09; 95% CI, 30.44 to 31.74, vs 21.81; 95% CI, 21.43 to 22.18, in 2018-2020); however, once born, extremely prematurely Black and Hispanic infants had a narrow survival advantage (IMR rate ratio, 0.87; 95% CI, 0.84 to 0.91, in 2018-2020). The rate of decrease in preterm IMR was higher in Black infants (-0.015) than in White (-0.013) and Hispanic infants (-0.010); however, the relative risk of preterm IMR among Black infants compared with White infants remained the same between 1995-1997 vs 2018-2020 (relative risk, 1.40; 95% CI, 1.38 to 1.44, vs 1.43; 95% CI, 1.39 to 1.46). The rate of decrease in preterm IMR was higher in nonsmokers compared with smokers (-0.015 vs -0.010, respectively), in those with high levels of education compared with those with intermediate or low (-0.016 vs - 0.010 or -0.011, respectively), and in those who had received adequate antenatal care compared with those who did not (-0.014 vs -0.012 for intermediate and -0.013 for inadequate antenatal care). Over time, the relative risk of preterm mortality widened within each of these subgroups. Conclusions and Relevance This study found that between 1995 and 2020, US preterm infant mortality improved among all categories of prematurity. Inequalities in preterm infant mortality based on maternal race and ethnicity have remained constant while socioeconomic disparities have widened over time.

Abstract
Infant's health care management at home was an important challenge for the families. Therefore, the policymakers provided a program as an extension to the care plan to implement at home and examine families' attitudes toward the program. Examination of the parents' attitude was a coincidence with COVID-19 pandemic in this study, a descriptive-analytical cross-sectional study that was conducted on 385 parents with infants less than 2 months old in the health centers of Isfahan-Iran. The samples were selected by stratified random sampling method. Data gathering was done through a researcher-made Likert questionnaire, which had 30 items and 3 domains including individual-cultural, educational-supportive, and environmental domains. The data were analyzed through the descriptive and analytical statistic. The results of the study revealed a mean score of 104.12 ± 11.69 on family attitude and their positive view toward the infant home-based care program. Also, the highest score was related to the individual-cultural domain 36.95 ± 4.44, educational-supportive 34.88 ± 5.04 and environmental domains 32.29 ± 3.98, respectively. In addition, a significant relationship was found between the mean score of the family attitude and age, the number of children, education, and place of care (P < .05). Based on the results of the study, the attitude of family toward infant home-based care is positive, and the challenges of parents in caring their infants at home can be reduced as the program is implemented.

Abstract
Preterm birth (PTB) is the leading cause of death in children under five, yet comprehensive studies are hindered by its multiple complex etiologies. Epidemiological associations between PTB and maternal characteristics have been previously described. This work used multiomic profiling and multivariate modeling to investigate the biological signatures of these characteristics. Maternal covariates were collected during pregnancy from 13,841 pregnant women across five sites. Plasma samples from 231 participants were analyzed to generate proteomic, metabolomic, and lipidomic datasets. Machine learning models showed robust performance for the prediction of PTB (AUROC = 0.70), time-to-delivery (r = 0.65), maternal age (r = 0.59), gravidity (r = 0.56), and BMI (r = 0.81). Time-to-delivery biological correlates included fetal-associated proteins (e.g., ALPP, AFP, and PGF) and immune proteins (e.g., PD-L1, CCL28, and LIFR). Maternal age negatively correlated with collagen COL9A1, gravidity with endothelial NOS and inflammatory chemokine CXCL13, and BMI with leptin and structural protein FABP4. These results provide an integrated view of epidemiological factors associated with PTB and identify biological signatures of clinical covariates affecting this disease.

Adverse neonatal outcomes and associated factors among mothers who gave birth through induced and spontaneous labor in public hospitals of Awi zone, Northwest Ethiopia: a comparative cross-sectional study. BMC Pregnancy Childbirth 2023; 23:307. [PMID: 37131132 PMCID: PMC10152696 DOI: 10.1186/s12884-023-05631-4] [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: 11/05/2022] [Accepted: 04/21/2023] [Indexed: 05/04/2023] Open
Abstract
BACKGROUND Adverse neonatal outcomes are one of the most common causes of neonatal mortality and morbidity. Empirical evidence across the world shows that induction of labor potentiates adverse neonatal outcomes. In Ethiopia, there has been limited data that compares the frequency of adverse neonatal outcomes between induced and spontaneous labor. OBJECTIVES To compare the prevalence of adverse neonatal outcomes between induced and spontaneous labor and to determine associated factors among women who gave birth in public hospitals of Awi Zone, Northwest Ethiopia. METHODS A comparative cross-sectional study was conducted at Awi Zone public hospitals from May 1 to June 30, 2022. A simple random sampling technique was employed to select 788 (260 induced and 528 spontaneous) women. The collected data were analyzed using statistical package for social science (SPSS) software version 26. The Chi-square test and an independent t-test were used for categorical and continuous variables, respectively. A binary logistic regression was used to assess the association between the outcome and explanatory variables. In the bivariate analysis, a p-value ≤ 0.2 at a 95% confidence interval was used to consider the variables in the multivariate analysis. Finally, statistical significance was stated at a p-value of less than 0.05. RESULT The adverse neonatal outcomes among women who gave birth through induced labor were 41.1%, whereas spontaneous labor was 10.3%. The odds of adverse neonatal outcomes in induced labor were nearly two times higher than in spontaneous labor (AOR = 1.89, 95% CI: 1.11-3.22). No education (AOR = 2.00, 95% CI: 1.56, 6.44), chronic disease (AOR = 3.99, 95% CI: 1.87, 8.52), male involvement (AOR = 2.23, 95% CI: 1.23, 4.06), preterm birth (AOR = 9.83, 95% CI: 8.74, 76.37), operative delivery (AOR = 8.60, 95% CI: 4.63, 15.90), cesarean section (AOR = 4.17, 95% CI: 1.94, 8.95), and labor complications (AOR = 5.16, 95% CI: 2.90, 9.18) were significantly associated factors with adverse neonatal outcomes. CONCLUSION AND RECOMMENDATION Adverse neonatal outcomes in the study area were higher. Composite adverse neonatal outcomes were significantly higher in induced labor compared to spontaneous labor. Therefore, it is important to anticipate the possible adverse neonatal outcomes and plan management strategies while conducting every labor induction.

Abstract
Preterm birth rate depending on parental educational level in recent years has not been surveyed in Japan. In this study, we showed the trend in preterm birth rate depending on parental educational level from 2000 to 2020 by linking data from the Census regarding individuals' educational level and parents in birth data of the vital statistics. Four types of parental educational level, namely junior high school, high school, technical school or junior college, and university or graduate school, were compared. Slope and relative indexes of inequality for preterm birth by educational level were computed by binomial models. Data on 3,148,711 births and 381,129,294 people were used in the analysis, and data on 782,536 singleton births were used after data linkage. The preterm birth rate (%) for junior high school graduate mothers and fathers was 5.09 and 5.20 in 2020, respectively. Contrarily, the preterm birth rate (%) for parents who graduated from a university or graduate school was 4.24 for mothers and 4.39 for fathers, and the rate tended to increase as educational level decreased, irrespective of parental gender. Results of inequality indexes showed that a statistically significant inequality by parental educational level persisted from 2000 to 2020.

Abstract
Necrotizing enterocolitis (NEC) is a complex disease with a multifactorial etiology. As the leading cause of intestinal morbidity and mortality among premature infants, many resources are being dedicated to neonatal care and molecular targets in the newborn intestine. However, NEC is heavily influenced by maternal and perinatal factors as well. Given its nature, preventive approaches to NEC are more likely to improve outcomes than new treatment strategies. Therefore, this review focuses on maternal, environmental, and racial factors associated with the development of NEC, with an emphasis on those that may be modifiable to decrease the incidence of the disease.

Arch Gynecol Obstet 2023; 307:343-378.

Abstract
PURPOSE Bariatric surgery increases the risk of lower birth weight, small-for-gestational-age (SGA) infants, and preterm birth in a subsequent pregnancy. However, the factors that contribute to these adverse birth outcomes are unclear. This review aimed to collate available information about risk factors of lower birth weight, SGA, and preterm birth following bariatric surgery. METHODS A literature search was conducted using five databases (PubMed, PsycINFO, EMBASE, Web of Science, and Cochrane Library) to obtain relevant studies. RESULTS A total number of 85 studies were included. Studies generally excluded surgery-to-conception interval, pregnancy complications, cigarette use, and maternal age as influencing factors of birth weight, SGA, or preterm birth. In contrast, most studies found that malabsorptive procedures, lower gestational weight gain, lower glucose levels, abdominal pain, and insufficient prenatal care were associated with an elevated risk of adverse birth outcomes. Findings were mixed regarding the effects of surgery-to-conception weight loss, pre-pregnancy body mass index, micronutrient deficiency, and lipid levels on birth outcomes. The examination of maternal microbiome profiles, placental function, alcohol use, and exercise was limited to one study; therefore, no conclusions could be made. CONCLUSION This review identified factors that appear to be associated (e.g., surgery type) or not associated (e.g., surgery-to-conception interval) with birth outcomes following bariatric surgery. The mixed findings and the limited number of studies on several variables (e.g., micronutrients, exercise) highlight the need for further investigation. Additionally, future studies may benefit from exploring interactions among risk factors and expanding to assess additional exposures such as maternal mental health.

Effect of fetal malposition, primiparous, and premature rupture of membrane on Neonatal Near miss mediated by grade three meconium-stained amniotic fluids and duration of the active first stage of labor: Mediation analysis. PLoS One 2023; 18:e0285280. [PMID: 37146028 PMCID: PMC10162561 DOI: 10.1371/journal.pone.0285280] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2022] [Accepted: 04/18/2023] [Indexed: 05/07/2023] Open
Abstract
BACKGROUND In many low-income countries, including Ethiopia, neonatal mortality remains a major concern. For every newborn that dies, many more neonates survived (near-miss neonates) the first 28 days after birth from life-threatening conditions. The generation of evidence on neonatal near-miss determinants could be a critical step in reducing neonatal mortality rates. However, studies causal pathway determinants are limited in Ethiopia. This study aimed to investigate the Neonatal Near-miss determinants in public health hospitals in Amhara Regional State, northwest Ethiopia. METHOD A cross-sectional study was conducted on 1277 mother-newborn pairs at six hospitals between July 2021 and January 2022. A validated interviewer-administered questionnaire and a review of medical records were used to collect data. Data were entered into Epi-Info version 7.1.2 and exported to STATA version 16 in California, America for analysis. The paths from exposure variables to Neonatal Near-Miss via mediators were examined using multiple logistic regression analysis. The adjusted odds ratio (AOR) and ß-coefficients were calculated and reported with a 95% confidence interval and a p-value of 0.05. RESULTS The proportion of neonatal near-misses was 28.6% (365/1277) (95% CI: 26-31%). Women who could not read and write (AOR = 1.67,95%CI:1.14-2.47), being primiparous (AOR = 2.48,95% CI:1.63-3.79), pregnancy-induced hypertension (AOR = 2.10,95% CI:1.49-2.95),being referred from other health facilities (AOR = 2.28,95% CI:1.88-3.29), premature rupture of membrane (AOR = 1.47,95% CI:1.09-1.98), and fetal malposition (AOR = 1.89,95% CI:1.14-3.16) were associated with Neonatal Near-miss. Grade III meconium stained amniotic fluid partially mediated the relationship between primiparous (ß = 0.517), fetal malposition (ß = 0.526), pregnant women referred from other health facilities (ß = 0.948) and Neonatal Near-Miss at P-value < 0.01. Duration of the active first stage of labour partially mediated the relationship between primiparous (ß = -0.345), fetal malposition (ß = -0.656), premature rupture of membranes (ß = -0.550) and Neonatal Near-Miss at P- value <0.01.It had also a significant indirect effect (ß = 0.581, P<0.001) on NNM with variables (primiparous, fetal malposition, and premature rupture of membranes). CONCLUSIONS The relationship between fetal malposition, primiparous, referred from other health facilities, premature rupture of membrane, and Neonatal Near miss were partially mediated by grade III meconium stained amniotic fluid and duration of the active first stage of labour. Early diagnosis of these potential danger signs and appropriate intervention could be of supreme importance in reducing NNM.

Abstract
BACKGROUND There is a lack of studies on methamphetamine (MA) exposure and morbidity in children beyond the perinatal period. OBJECTIVES We compared morbidity in children (0-3 years) with prenatal MA exposure to opioid-exposed and to non-exposed children. METHODS We used data from a Czech nationwide, registry-based cohort study (2000-2014). Children, who reached 3 years of age, of mothers hospitalized with (i) MA use disorder during pregnancy (MA; n = 194), (ii) opioid use disorder during pregnancy (opioids; n = 166), and (iii) general population (GP; n = 1,294,349) with no recorded history of substance use disorder (SUD). Information on inpatient contacts, length of stay, and diagnoses (International Statistical Classification of Diseases and Related Health Problems 10th Revision [ICD-10]) were assessed. Crude and adjusted odds ratios (aOR), 95% confidence interval (CI) for the risk of hospitalization, and for getting diagnosis from the ICD-10 diagnosis chapters were calculated using binary logistic regression. A stratified analysis on hospitalizations with SUD of mothers was performed. RESULTS No significant differences were found in the measures of hospitalization between the MA and opioid groups. Children prenatally exposed to MA and opioids had higher numbers of hospitalizations and diagnoses and longer stays in hospital than children in the GP. Increased risks of certain infectious and parasitic diseases were found in both MA (aOR = 1.6; CI: 1.1-2.3) and opioid (aOR = 1.9; 1.3-2.8) groups as compared to the GP group. The most pronounced difference in stratified analysis on maternal hospitalizations related to SUD after birth was observed for injury, poisoning, and certain other consequences of external causes in the strata of the MA group who had hospitalized mothers (aOR 6.3, 1.6-24.6) compared to the strata without maternal hospitalizations (aOR 1.4, 0.9-2.3). CONCLUSION This study suggests that children born to mothers using MA during pregnancy have similar morbidity during the first 3 years of life but higher than the GP. The excess of risk was primarily due to infections and injuries in the MA group.

Abstract
Introduction Early identification and intervention of neurodevelopmental impairment in preterm infants may significantly improve their outcomes. This study aimed to build a prediction model for short-term neurodevelopmental impairment in preterm infants using machine learning method. Methods Preterm infants with gestational age < 32 weeks who were hospitalized in The Maternal and Child Health Hospital of Guangxi Zhuang Autonomous Region, and were followed-up to 18 months corrected age were included to build the prediction model. The training set and test set are divided according to 8:2 randomly by Microsoft Excel. We firstly established a logistic regression model to screen out the indicators that have a significant effect on predicting neurodevelopmental impairment. The normalized weights of each indicator were obtained by building a Support Vector Machine, in order to measure the importance of each predictor, then the dimension of the indicators was further reduced by principal component analysis methods. Both discrimination and calibration were assessed with a bootstrap of 505 resamples. Results In total, 387 eligible cases were collected, 78 were randomly selected for external validation. Multivariate logistic regression demonstrated that gestational age(p = 0.0004), extrauterine growth restriction (p = 0.0367), vaginal delivery (p = 0.0009), and hyperbilirubinemia (0.0015) were more important to predict the occurrence of neurodevelopmental impairment in preterm infants. The Support Vector Machine had an area under the curve of 0.9800 on the training set. The results of the model were exported based on 10-fold cross-validation. In addition, the area under the curve on the test set is 0.70. The external validation proves the reliability of the prediction model. Conclusion A support vector machine based on perinatal factors was developed to predict the occurrence of neurodevelopmental impairment in preterm infants with gestational age < 32 weeks. The prediction model provides clinicians with an accurate and effective tool for the prevention and early intervention of neurodevelopmental impairment in this population.

Maternal characteristics associated with referral to obstetrician-led care in low-risk pregnant women in the Netherlands: A retrospective cohort study. PLoS One 2023; 18:e0282883. [PMID: 36921011 PMCID: PMC10016726 DOI: 10.1371/journal.pone.0282883] [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: 09/07/2021] [Accepted: 02/27/2023] [Indexed: 03/16/2023] Open
Abstract
BACKGROUND In the Netherlands, maternity care is divided into midwife-led care (for low-risk women) and obstetrician-led care (for high-risk women). Referrals from midwife-led to obstetrician-led care have increased over the past decade. The majority of women are referred during their pregnancy or labour. Referrals are based on a continuous risk assessment of the health and characteristics of mother and child, yet referral for non-medical factors and characteristics remain unclear. This study investigated which maternal characteristics are associated with women's referral from midwife-led to obstetrician-led care. MATERIALS AND METHODS A retrospective cohort study in one midwife-led care practice in the Netherlands included 1096 low-risk women during January 2015-17. The primary outcomes were referral from midwife-led to obstetrician-led care in (1) the antepartum period and (2) the intrapartum period. In total, 11 maternal characteristics were identified. Logistic regression models of referral in each period were fitted and stratified by parity. RESULTS In the antepartum period, referral among nulliparous women was associated with an older maternal age (aOR, 1.07; 95%CI, 1.05-1.09), being underweight (0.45; 0.31-0.64), overweight (2.29; 1.91-2.74), or obese (2.65; 2.06-3.42), a preconception period >1 year (1.34; 1.07-1.66), medium education level (0.76; 0.58-1.00), deprivation (1.87; 1.54-2.26), and sexual abuse (1.44; 1.14-1.82). Among multiparous women, a referral was associated with being underweight (0.40; 0.26-0.60), obese (1.61; 1.30-1.98), a preconception period >1 year (1.71; 1.27-2.28), employment (1.38; 1.19-1.61), deprivation (1.23; 1.03-1.46), highest education level (0.63; 0.51-0.80), psychological problems (1.24; 1.06-1.44), and one or multiple consultations with an obstetrician (0.68; 0.58-0.80 and 0.64; 0.54-0.76, respectively). In the intrapartum period, referral among nulliparous women was associated with an older maternal age (1.02; 1.00-1.05), being underweight (1.67; 1.15-2.42), a preconception period >1 year (0.42; 0.31-0.57), medium or high level of education (2.09; 1.49-2.91 or 1.56; 1.10-2.22, respectively), sexual abuse (0.46; 0.33-0.63), and multiple consultations with an obstetrician (1.49; 1.15-1.94). Among multiparous women, referral was associated with an older maternal age (1.02; 1.00-1.04), being overweight (0.65; 0.51-0.83), a preconception period >1 year (0.33; 0.17-0.65), non-Dutch ethnicity (1.98; 1.61-2.45), smoking (0.75; 0.57-0.97), sexual abuse (1.49; 1.09-2.02), and one or multiple consultations with an obstetrician (1.34; 1.06-1.70 and 2.09; 1.63-2.69, respectively). CONCLUSIONS This exploratory study showed that several non-medical maternal characteristics of low-risk pregnant women are associated with referral from midwife-led to obstetrician-led care, and how these differ by parity and partum period.

Abstract
Abstract
Background
Congenital anomalies are associated with several clinical and epidemiological complications. Following the Zika epidemic onset in Latin America, the incidence of congenital anomalies increased in Brazil. This study aimed to determine the frequency of congenital anomalies in one Brazilian state and assess potential factors associated with them.
Methods
This cross-sectional descriptive study was based on data concerning congenital anomalies recorded in the Brazilian Live-Born Information System during the Zika epidemic in Mato Grosso do Sul state from 2015 to 2018. Congenital anomalies were stratified according to year of birth and classified using ICD-10 categories.
Results
In total, 1,473 (0.85%) anomalies were registered. Within the number of cases recorded, microcephaly showed the greatest frequency and variations, with a 420% increase observed in the number of cases from 2015 to 2016. We identified an increase in the incidence of central nervous system anomalies, with the highest peak observed in 2016 followed by a subsequent decrease. Musculoskeletal, nervous, and cardiovascular system anomalies, and eye, ear, face, and neck anomalies represented 73.9% of all recorded anomalies. There was an increased chance of congenital anomalies in uneducated (odds ratio [OR] 5.56, 95% confidence interval [CI] 2.61–11.84) and Indigenous (OR 1.32, 95% CI 1.03–1.69) women, as well as among premature births (OR 2.74, 95% CI 2.39–3.13).
Conclusions
We estimated the incidence of congenital anomalies during the Zika epidemic. Our findings could help to support future research and intervention strategies in health facilities to better identify and assist children born with congenital anomalies.

Maternal and neonatal outcomes with the use of long acting, compared to intermediate acting basal insulin (NPH) for managing diabetes during pregnancy: a systematic review and meta-analysis. Diabetol Metab Syndr 2022; 14:154. [PMID: 36271431 PMCID: PMC9585834 DOI: 10.1186/s13098-022-00925-7] [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: 08/04/2022] [Accepted: 10/13/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND To assess the impact of long-acting insulin analogues, compared to intermediate acting neutral protamine Hagedron (NPH), on maternal, perinatal and neonatal outcomes. METHODS Studies for inclusion in the review were identified using a structured search strategy in PubMed, Scopus and Cochrane Central Register of Controlled Trials (CENTRAL) database. Studies that were randomized controlled trials or observational in design were considered for inclusion. Eligible studies should have compared the maternal, perinatal and neonatal outcomes between pregnant women with gestational diabetes mellitus (GDM) managed by intermediate acting (NPH) and by long-acting insulin analogues. Statistical analysis was performed using STATA software. RESULTS We found 17 studies to be eligible for inclusion. The mean gestational weight gain and risk of maternal hypoglycaemia, hypertensive disorder, caesarean delivery, spontaneous abortion, endometritis and wound infection or dehiscence were similar among pregnant women with GDM managed using long-acting insulin analogues and NPH. Those receiving long-acting insulin analogues had significantly lower HbA1c values in the second (WMD - .09, 95% CI 0.12, - 0.06; N = 4) and third trimester (WMD - 0.08, 95% CI - 0.14, - 0.02; N = 12). The mean gestational age and birth weight and risk of perinatal mortality, prematurity, large for gestational age, small for gestational age, shoulder dystocia and congenital abnormalities was similar among babies in both groups. No statistically significant differences in risk of admission to neonatal intensive care unit, respiratory distress, neonatal hypoglycaemia, 5 min APGAR score of < 7, neonatal hyperbilirubinemia and sepsis was observed. The quality of pooled evidence, as per GRADE criteria, was judged to be "very low" for all the maternal and neonatal outcomes considered. CONCLUSIONS Findings suggest no significant differences in the maternal, perinatal and neonatal outcomes between intermediate and long-acting insulin analogues. The results provide support for use of long-acting insulin analogues in women with GDM. However, evidence is still needed from high quality randomized controlled trials to arrive at a recommendation for inclusion in routine clinical care.

EClinicalMedicine 2022; 50:101523. [PMID: 35784441 PMCID: PMC9241127 DOI: 10.1016/j.eclinm.2022.101523] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2022] [Revised: 05/30/2022] [Accepted: 05/31/2022] [Indexed: 12/01/2022] Open
Abstract
BACKGROUND Neonatal acute respiratory distress syndrome (ARDS) is a critical clinical disease with high disability and mortality rates. Early identification and treatment of neonatal ARDS is critical. This study aimed to build a perinatal prediction nomogram for early prediction of neonatal ARDS. METHODS A prediction model was built including 243 late-preterm and full-term infants from Daping Hospital in Chongqing, China, hospitalised between Jan 1, 2018 and Dec 31, 2019. 80 patients from the Children's Hospital in Chongqing, China, hospitalised between Jan 1, 2018 and June 30, 2018 were considered for external validation. Multivariate logistic regression was performed to identify independent predictors and establish a nomogram to predict the occurrence of neonatal ARDS. Both discrimination and calibration were assessed by bootstrapping with 1000 resamples. FINDINGS Multivariate logistic regression demonstrated that mother's education level (odds ratio [OR] 0·478, 95% confidence interval [CI] 0·324-0·704), premature rupture of membrane (OR 0·296, 95% CI 0·133-0·655), infectious disease within 7 days before delivery (OR 0·275, 95% CI 0·083-0·909), hospital level (OR 2·479, 95% CI 1·260-4·877), and Apgar 5-min score (OR 0·717, 95% CI 0·563-0·913) were independent predictors for neonatal ARDS in late-preterm and full-term infants, who experienced dyspnoea within 24 h after birth and required mechanical ventilation. The area under the curve and concordance index of the nomogram constructed from the above five factors were 0·760 and 0·757, respectively. The Hosmer-Lemeshow test showed that the model was a good fit (P = 0.320). The calibration curve of the nomogram was close to the ideal diagonal line. Furthermore, the decision curve analysis demonstrated significantly better net benefit in the model. The external validation proved the reliability of the prediction nomogram. INTERPRETATION A nomogram based on perinatal factors was developed to predict the occurrence of neonatal ARDS in late-preterm and full-term infants who experienced dyspnoea within 24 h after birth and required mechanical ventilation. It provided clinicians with an accurate and effective tool for the early prediction and timely management of neonatal ARDS. FUNDING No funding was associated with this study.

Abstract
PURPOSE Several studies link maternal cardiovascular disease (CVD) to maternal and fetal morbidity and mortality. This study describes the profile of maternal, obstetric, and neonatal outcomes among pregnant women with CVD in a tertiary hospital in the Philippines. It identifies the clinical and sociodemographic variables associated with these outcomes. MATERIALS AND METHODS A single-center, retrospective analysis of pregnant women admitted for delivery at the Philippine General Hospital from 2015 to 2019 was performed. Of these patients, pregnant women with CVD were identified as the cohort for this study. Data on clinical and sociodemographic factors, maternal major adverse cardiovascular events, neonatal adverse clinical events, and obstetric complications were collected. Logistic regression analysis was performed to determine the odds ratio for the risk factors for small-for-gestational-age (SGA) babies and preterm birth. RESULTS Among 30,053 delivery admissions in the Philippine General Hospital from 2015 to 2019, 293 (0.98%) pregnant women had CVD. Of the CVDs present in this cohort, congenital heart diseases (n = 119, 40.6%) were the most common, followed by rheumatic heart disease (n = 109, 37.2%). Maternal adverse events were rarely observed. Four women experienced symptomatic arrhythmias, two presented with worsening heart failure, three experienced thromboembolic events, and one had cerebrovascular infarction. There was no reported maternal death, cardiac arrest, shock, or acute renal failure. The majority (69.3%) of the women included in the study were delivered by spontaneous vaginal delivery and assisted vaginal delivery by vacuum or forceps; however, a significant portion of these women had undergone cesarean section. Almost all the study cohort delivered live births, with most neonates being delivered at 37-38 weeks gestational age (83.6%) and only 16.0% born preterm. However, a significant portion, a third of the neonates, were classified as having low birth weight. Around 17.4% of neonates born from gravidocardiac mothers were admitted neonatal intensive care unit. Conditions associated with preterm birth were low educational attainment, previous history of early neonatal death, maternal low ejection fraction, and abnormal maternal left ventricular geometry. The conditions associated with SGA babies were high gravidity and parity, a history of abortion/stillbirth, a history of previous cesarean section delivery, low ejection fraction, a history of multiple gestations, and higher BMI. CONCLUSION In this cohort study, adverse maternal outcomes were rarely observed. CVD in pregnancy is associated with an increased risk of preterm birth and SGA babies. We identified certain maternal conditions and sociodemographic factors associated with these outcomes. Despite having CVD, our study cohort had no mortality from the pregnancy.

Abstract
Preterm birth (PTB) is a phenomenon that brings risks and challenges for the survival of the newborn child. Despite many advances in research, not all the causes of PTB are already clear. It is understood that PTB risk is multi-factorial and can also be associated with socioeconomic factors. Thereby, this article seeks to use unsupervised learning techniques to stratify PTB risk in Brazil using only socioeconomic data. Through the use of datasets made publicly available by the Federal Government of Brazil, a new dataset was generated with municipality-level socioeconomic data and a PTB occurrence rate. This dataset was processed using various unsupervised learning techniques, such as k-means, principal component analysis (PCA), and density-based spatial clustering of applications with noise (DBSCAN). After validation, four clusters with high levels of PTB occurrence were discovered, as well as three with low levels. The clusters with high PTB were comprised mostly of municipalities with lower levels of education, worse quality of public services-such as basic sanitation and garbage collection-and a less white population. The regional distribution of the clusters was also observed, with clusters of high PTB located mostly in the North and Northeast regions of Brazil. The results indicate a positive influence of the quality of life and the offer of public services on the reduction in PTB risk.

DNA methylation signatures in cord blood associated with birthweight are enriched for dmCpGs previously associated with maternal hypertension or pre-eclampsia, smoking and folic acid intake. Epigenetics 2022; 17:405-421. [PMID: 33784941 PMCID: PMC8993070 DOI: 10.1080/15592294.2021.1908706] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2020] [Revised: 02/23/2021] [Accepted: 03/17/2021] [Indexed: 01/22/2023] Open
Abstract
Many epidemiological studies have linked low birthweight to an increased risk of non-communicable diseases (NCDs) in later life, with epigenetic proceseses suggested as an underlying mechanism. Here, we sought to identify neonatal methylation changes associated with birthweight, at the individual CpG and genomic regional level, and whether the birthweight-associated methylation signatures were associated with specific maternal factors. Using the Illumina Human Methylation EPIC array, we assessed DNA methylation in the cord blood of 557 and 483 infants from the UK Pregnancies Better Eating and Activity Trial and Southampton Women's Survey, respectively. Adjusting for gestational age and other covariates, an epigenome-wide association study identified 2911 (FDR≤0.05) and 236 (Bonferroni corrected p ≤ 6.45×10-8) differentially methylated CpGs (dmCpGs), and 1230 differentially methylated regions (DMRs) (Stouffer ≤0.05) associated with birthweight. The top birthweight-associated dmCpG was located within the Homeobox Telomere-Binding Protein 1 (HMBOX1) gene with a 195 g (95%CI: -241, -149 g) decrease in birthweight per 10% increase in methylation, while the top DMR was located within the promoter of corticotropin-releasing hormone-binding protein (CRHBP). Furthermore, the birthweight-related dmCpGs were enriched for dmCpGs previously associated with gestational hypertension/pre-eclampsia (14.51%, p = 1.37×10-255), maternal smoking (7.71%, p = 1.50 x 10-57) and maternal plasma folate levels during pregnancy (0.33%, p = 0.029). The identification of birthweight-associated methylation markers, particularly those connected to specific pregnancy complications and exposures, may provide insights into the developmental pathways that affect birthweight and suggest surrogate markers to identify adverse prenatal exposures for stratifying for individuals at risk of later NCDs.

Abstract
OBJECTIVE The objective is to determine the association between maternal race/ethnicity, insurance, education level, and pregnancy outcomes. METHODS We queried the U.S. vital statistics records from 2015 to 2019 to analyze all deliveries. Using a multivariate analysis model, we determined the interaction between maternal race, insurance, education, and pregnancy outcomes. The outcome measures were the 5-min Apgar score, neonatal unit admission, neonates receiving assisted ventilation > 6 hours, mothers requiring blood transfusion, and the intensive care unit admission. RESULT There were 13,213,732 deliveries that met our inclusion criteria. In the study population, 52.7% were white, 14.1% blacks, 22.9% Hispanics, and 10.4% belonged to other races. 37.5% of the women had a high school education, 49.1% had a college education, and 12.3% had advanced degrees. Black mothers with high school education were more likely to require blood transfusion following delivery than Whites at the same education level, OR=1.08 (95% CI 1.05-1.11, p < 0.05). They were also more likely to be admitted into intensive care. The difference only disappeared among blacks with advanced education (OR=1.0; 95% CI 0.89-1.12, p > 0.05). Across all races/ethnicities, private insurance and advanced education were associated with better pregnancy outcomes. CONCLUSION In the U.S., women with high socioeconomic status have better pregnancy outcomes across all races/ethnicities.

Abstract
Background All over the world, especially in the developed countries, maternal age at birth is rising. This study aimed to assess the role of maternal age on the occurrence of preterm birth (PTB) in a large birth cohort of Lombardy Region, Northern Italy. Methods This population-based study used data from regional healthcare utilization databases of Lombardy to identify women who delivered between 2007 and 2017. PTBs were defined as births before 37 completed weeks of gestation and considered according to the gestational age (two categories: < 32 weeks and 32 to 36 weeks). Six maternal age groups were defined (< 20, 20–24, 25–29, 30–34, 35–39, ≥40 years). Logistic regression models were fitted to estimate the crude and adjusted odds ratio (aOR) and the corresponding 95% confidence interval (CI) for PTB among different maternal age groups. Analyses were separately performed according to type of pregnancy (singletons and multiples). Reference group was the age group with the lowest frequency of PTB. Results Overall, 49,759 (6.6%) PTBs were observed, of which 41,807 were singletons and 7952 were multiples. Rates of PTB were lowest in the women aged 25–29 years among singletons and in the 30–34 years old group among multiples. Our results described a U-shaped association between maternal age and risk of PTB. In particular, the risk of a singleton PTB between 32 and 36 weeks was significantly higher for women aged less than 20 years (aOR = 1.16, CI 95%: 1.04–1.30) and more than 40 years (aOR = 1.62 CI 95%: 1.54–1.70). The highest risk of a multiple delivery between 32 and 36 weeks was observed among women aged less than 25 years and more than 40 years (aOR = 1.79, CI 95%: 1.01–3.17, aOR = 1.47, CI 95%: 1.16–1.85 and aOR = 1.36, CI 95%: 1.19–1.55 respectively for < 20, 20–24 and > 40 age categories). PTB before 32 completed weeks occurred more frequently in the same age categories, except that among multiples no association with advanced maternal age emerged. Conclusion Our study suggested that, after adjustment for potential confounders, both advance and young maternal age were associated with an increased risk of PTB.

Abstract
By using 64,270 daily observations from a large hospital in Guangzhou between 2017 and 2019, we analyzed the impact of extreme temperature on the health of newborns via OLS regression with time fixed effect. Given that the short-term temperature change can be regarded as exogenous and random, solving the potential endogenous problem is critical. We find that extreme temperature negatively affects the health of newborns. The Apgar score, an index for evaluating neonatal health, decreases by 0.008 (0.029%) when the duration of extreme temperature events increases by a day. A series of robustness checks verify the reliability of this negative effect. Extreme temperature also has a particularly serious effect on the health of newborns whose mothers have poor education. By gradually extending the observation period, we find that the effect of extreme temperature on neonatal health is mainly concentrated 1-6 weeks before delivery, whereas the effect of extreme temperature on hospitalization cost is mainly concentrated 4-8 weeks before delivery. This paper provides a valuable reference for evaluating the health and social costs of extreme weather, and our findings are conducive to the construction of climate-resilient health systems, especially in Guangzhou.

Abstract
BACKGROUND The relationship between maternal education and adverse pregnancy outcomes is well documented. However, limited research has investigated maternal educational disparities in adverse pregnancy outcomes in China. This study examined maternal educational inequalities associated with adverse pregnancy outcomes in rural China. METHODS We conducted a population-based cohort study using participants enrolled in the National Free Preconception Health Examination Project in Yunnan province from 2010 to 2018. The primary outcome was stillbirth, and the secondary outcome was adverse pregnancy outcomes, defined as a composite event of stillbirth, preterm birth or low birth weight. The study was restricted to singleton births at 20-42 weeks' gestation. Univariate and multivariate log-binomial regression models were performed to estimate crude risk ratios (RRs) and confounding-adjusted RRs (ARRs) for stillbirth and adverse pregnancy outcomes according to maternal education level. RESULTS A total of 197 722 singleton births were included in the study. Compared with mid-educated women, low-educated women were at a significantly increased risk of stillbirth (ARR, 1.20; 95% CI, 1.05 to 1.38) and adverse pregnancy outcomes (ARR, 1.11; 95% CI, 1.07 to 1.16). However, the risk of stillbirth (ARR, 1.16; 95% CI, 1.01 to 1.35) was significantly higher for high-educated women compared with mid-educated women. CONCLUSION Compared with women with medium education level, women with lower education level were more likely to experience adverse pregnancy outcomes, including stillbirth, and women with higher education level were more likely to experience stillbirth.

Adverse Perinatal Outcomes Among Grand Multiparous and Low Multiparous Women and Its Associated Factors in North Shewa Zone Public Hospitals: The Role of Parity. Int J Gen Med 2021; 14:6539-6548. [PMID: 34675621 PMCID: PMC8518478 DOI: 10.2147/ijgm.s333033] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2021] [Accepted: 10/01/2021] [Indexed: 12/31/2022] Open
Abstract
Background Adverse perinatal outcomes are the major cause of neonatal morbidity, mortality, and long-term physical and psychological consequences. Contradicting evidence across studies was reported about the impact of grand multiparity on adverse perinatal outcomes. Older literature reported increased incidence of perinatal complications in grand multiparas, but, recent reports failed to support this finding. In addition, there is a paucity of comparative studies on perinatal outcomes. Thus, the study aimed to compare the perinatal outcomes in grand multiparous (GM) and low multiparous (LM) women who give birth in North Shewa Zone Public Hospitals, Ethiopia, 2021. Methods A comparative cross-sectional study was done among 540 (180 GM and 360 LM) women from January 1 to March 30, 2021. The data were collected using a structured and pre-tested questionnaire through interviews and reviewing patient charts. SPSS version 25 was used for data analysis. The data were entered using Epi-Data version 4.6. The Hosmer–Lemeshow goodness-of-fit was applied to test for model fitness. The statistical significance level was declared at a p-value of ≤0.05. Results In this study, the prevalence of adverse perinatal outcomes was 14.1% (95% CI: 10.9–17.2). Stillbirth/IUFD (33.3%) and low APGAR score (60%) were frequently occurred complications in grand multiparas. Nevertheless, meconium aspiration (26%), admission to NICU (65.2%), macrosomia (61%), and prematurity (52.2%) were higher in low multiparous women. Age above 35 years (AOR (CI) = 2.61 (1.23–5.53)), rural residence (AOR (CI) = 8.31 (3.05–22.6)), being a government employee (AOR (CI) = 0.19 (0.05–0.69)), lack of antenatal care (AOR (CI) = 9.76 (3.03–31.5)), and previous pregnancy complications (AOR (CI) = 3.10 (1.63–5.90)) were significant predictors of adverse perinatal outcomes. However, parity did not show a statistically significant association with perinatal outcomes. Conclusion Maternal age, residence, occupation, lack of antenatal care, and previous pregnancy complications were significant associates of perinatal outcome. There was no statistically significant difference in perinatal outcome between GM and LM women. Socio-economic development, good antenatal care, and early identification and treatment of complications are needed regardless of parity.

Abstract
BACKGROUND Prior studies have reported decreases in the preterm delivery incidence during the COVID-19 pandemic. However, the findings are inconsistent. Given the wide disparities in the pandemic's impact across communities, neighborhood deprivation may explain the observed variation in the relationship between the COVID-19 pandemic and preterm delivery. OBJECTIVE To characterize the changes in the incidence of preterm delivery during the COVID-19 pandemic with attention to the effect modification introduced by neighborhood hardship. STUDY DESIGN This retrospective cohort study included all the pregnant patients who delivered at an urban tertiary care hospital during the pandemic (April–November 2020) or before the pandemic (April–November 2019). We compared the incidence of preterm delivery, spontaneous preterm delivery, and medically indicated preterm delivery before 37 weeks’ gestation across epochs. Planned analyses stratified the cohorts by neighborhood deprivation metrics defined by the residential zip code; the metrics included the median neighborhood household income and the hardship index (a composite index including dependency, educational attainment, unemployment, poverty, per capita income, and crowded housing). The Breslow-Day test for homogeneity assessed the association of the delivery epoch and neighborhood deprivation with the preterm delivery outcomes. RESULTS Of 16,544 eligible deliveries, 8.7% occurred preterm. The incidences of preterm delivery (8.4% vs 9.0%; P=.17), spontaneous preterm delivery (5.0 vs 5.4%; P=.27), and medically indicated preterm delivery (3.2% vs 3.5%; P=.47) were similar in the pandemic and prepandemic epochs. However, the preterm delivery (odds ratio, 0.78; 95% confidence interval, 0.64–0.96) and spontaneous preterm delivery (odds ratio, 0.76; 95% confidence interval, 0.59–0.99) decreased from the prepandemic to the pandemic epoch in those living in neighborhoods <50th percentile for median income (Breslow-Day P values.047 and.036, respectively). Similarly, the preterm delivery (odds ratio, 0.78; 95% confidence interval, 0.64–0.97) and spontaneous preterm delivery (odds ratio, 0.74; 95% confidence interval, 0.57–0.98) decreased for those inhabiting the neighborhoods in the highest-hardship quartile (Breslow-Day P values.045 and.029, respectively). CONCLUSION The populations residing in socioeconomically disadvantaged neighborhoods experienced reductions in preterm delivery during the COVID-19 pandemic. Neighborhood-level social determinants of health offer insight into the complex etiologies that contribute to preterm delivery and provide opportunities for public health and equity-focused prevention strategies.

Abstract
OBJECTIVE Studies about the epidemiology and risk factors of late onset of sepsis (LOS) in preterm very low birth weight (PVLBW) infants of developing countries are limited and variable. The objective of this study was to explore the epidemiology, risk factors and pathogens of LOS in VLBW infants in a Chinese tertiary hospital. METHODS Data concerning demographies, pathogens, risk factors and outcomes of LOS were collected in a cohort of 710 VLBW infants discharged from January 2012 to December 2018. Chi-square, t-test and multivariable logistic regression analysis were used to identify risk factors. RESULTS The overall incidence of LOS was 24.08% and blood culture-proven sepsis was 19.58%. Gram-negative bacteria accounted for 57.93%, and 32.41% of the isolates were Klebsiella pneumoniae. LOS led to a longer hospital stay, higher hospitalization cost and higher mortality compared to infants without LOS. Mortality in Gram-negative or fungi LOS was higher than in Gram-positive LOS. The factor of PVLBW infants with registered permanent residence (PR) was associated with 80% lower likelihood of LOS compared to those without registered PR (P = 0.000, 95% CI 0.096-0.420). Infants with thrombocytopenia had 2.5 times LOS of control (P = 0.014, CI 1.210-5.132). Duration of parenteral nutrition was a risk of LOS (P = 0.009, CI 1.010-1.069). CONCLUSION Gram-negative bacteria, especially Klebsiella pneumonia, were the dominant pathogens in this study. Social factors might be a risk of LOS in PVLBW infants in developing countries. Taking measures to reduce the duration of parenteral nutrition may be helpful in decreasing the incidence of LOS. Awareness of thrombocytopenia may help to recognized diagnosis of LOS.

Abstract
Even though reduction of neonatal mortality is needed to achieve Sustainable Development Goals 2030, advanced maternal age is still an independent and a substantial risk factor for different adverse perinatal outcomes, in turn causes neonatal morbidity and mortality. In Ethiopia, research has validated that advanced maternal age is a significant factor in adverse perinatal outcomes, but researches which addressed or estimated its adverse perinatal outcomes are limited, reported inconsistent result and specifically no study was done in the study area. Therefore, this study was aimed to compare adverse perinatal outcomes and its associated factors among women with adult and advanced maternal age pregnancy in Northwest Ethiopia. Comparative cross-sectional study was conducted in Awi Zone, public hospitals, Northwest Ethiopia. Systematic random sampling was employed to select 348 adult and 176 advanced aged pregnant women. Structured questionnaire were used to collect the data. The collected data were analyzed using Statistical Package for the Social Sciences version 25. Binary and multivariate logistic regressions were fitted to assess the association between adverse perinatal outcomes and explanatory variables. P-value less than 0.05 was used to declare statistical significance. Significant percentage of advanced aged women (29.1%) had adverse perinatal outcomes compared to (14.5%) adult aged women. Similarly, proportion low birth weight, preterm birth and low Apgar score were significantly higher among advanced maternal age. The odds of composite adverse perinatal outcomes were higher among advanced maternal age women when compared to adult aged women (AOR 2.01, 95% CI 1.06, 3.79). No formal education (AOR 2.75, 95% CI 1.27, 5.95), short birth interval (AOR 2.25, 95% CI 1.07, 4.73) and complications during pregnancy (AOR 2.12, 95% CI 1.10, 4.10) were also factors significantly associated with adverse perinatal outcomes. Being advanced maternal age is at higher risk for adverse perinatal outcomes compared to adult aged women. Maternal illiteracy, short birth interval and complications during pregnancy were also significantly associated with adverse perinatal outcomes. Access of equal education, provision of family planning and perinatal care (including early detection and management of complication) is recommended.

Abstract
Associations between environmental tobacco smoke (ETS) and the risk of adverse birth outcomes may be confounded. We aimed to clarify the associations of ETS before and during pregnancy with the risk of adverse birth outcomes and determine whether the associations were modified by key potential confounders. A total of 7147 non-smoking mothers from the Tongji Maternal and Child Health Cohort (TMCHC) in Wuhan, China, were included in the final analyses. ETS status was self-reported by pregnant women at their first antenatal care visit before 16 gestational weeks. Information on birth outcomes was extracted from delivery records. Poisson regression was used to identify the association between ETS before and during pregnancy and the risk of adverse birth outcomes. Exposures to ETS before and during pregnancy were reported by 645 (9.0%) and 464 (6.5%) mothers, respectively. Compared with no ETS, continued ETS during pregnancy was associated with an increased risk of preterm birth (PTB) (RR: 1.55, 95% CI: 1.07, 2.25) after adjustment for potential confounders. The association remained consistent in medically indicated PTB and late PTB. The risk of PTB associated with continued ETS during pregnancy was significantly increased in mothers more educated (P for interaction < 0.05). However, the increased risk of low birth weight (LBW) or small for gestational age (SGA) births by ETS during pregnancy was not observed. Exposure to ETS during pregnancy was associated with a higher risk of PTB, but not LBW or SGA births in a Chinese birth cohort.

Lack of concern about body image and health during pregnancy linked to excessive gestational weight gain and small-for-gestational-age deliveries: the Japan Environment and Children's Study. BMC Pregnancy Childbirth 2021; 21:396. [PMID: 34020606 PMCID: PMC8139142 DOI: 10.1186/s12884-021-03827-0] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2020] [Accepted: 04/22/2021] [Indexed: 11/29/2022] Open
Abstract
Background Pregnant women in Japan express various reasons for limiting gestational weight gain (GWG). We aimed to identify and characterise groups where the women share common reasons to limit GWG and to examine how these groups are associated with inappropriate GWG and abnormal foetal size. Methods We prospectively studied information from the Japan Environment and Childrens Study (JECS) on 92,539 women who gave birth to live singletons from 2011 through 2014. Pregnant women were recruited during early pregnancy. Their reasons for limiting GWG and other information were collected through self-reported questionnaires and medical records. We applied latent class analysis to group the women based on their reported reasons. We used multinomial logistic regression to compare the risks of inappropriate (inadequate and excessive) GWG and abnormal foetal size (determined by new-born weight for gestational age) between the identified groups. Results We identified three groups: Group 1 (76.7%), concerned about delivery and new-born health (health-conscious women); Group 2 (14.5%), concerned about body shape, delivery, and new-born health (body-shape- and health-conscious women); and Group 3 (8.8%), women without strong reasons to limit GWG (women lacking body-shape and health consciousness). Compared with Group 1 members, Group 2 members tended to be younger, have lower pre-pregnancy weight, be unmarried, be nulliparous, have practiced weight loss before pregnancy, and not have chronic medical conditions. Group 3 members tended to be less educated, unmarried, multiparous, smokers, and have a higher prevalence of pre-pregnancy underweight and previous caesarean delivery. Relative to Group 1, Group 2 had a lower unadjusted risk for inadequate GWG (relative risk ratio [RRR]=0.86, 95% CI: 0.810.90) and large-for-gestational-age birth (RRR=0.91, 95% CI 0.860.97), whereas Group 3 had a higher unadjusted risk for excessive GWG (RRR=1.36, 95% CI: 1.291.43) and small-for-gestational-age (SGA) births (RRR=1.15, 95% CI: 1.051.25). Conclusions In this Japanese nationwide birth cohort study, pregnant women who were less conscious about body shape and health had complex risks for excessive GWG and SGA birth. Health care providers should consider a womans perception of GWG when addressing factors affecting GWG and foetal growth.

Abstract
OBJECTIVE To assess and compare the associations between household socioeconomic (SES) factors with birth outcomes (low birth weight (LBW), small-for-gestational age (SGA) and preterm birth (PTB)) in the Democratic Republic of Congo (DRC) and South Africa (SA). METHODS Cross-sectional data of mother-newborn pairs collected in 2017 in the DRC were compared with mother-newborn pairs data from the SA Soweto first 1000-days pregnancy cohort study (2013-2016). Country-specific and pooled multivariable logistic regressions analyses assessed the associations between maternal education, marital status, and housing with LBW, SGA, and PTB adjusted for maternal anthropometry and obstetric factors. RESULTS 1084 mother-newborn pairs were recruited (DRC: 256; SA: 828). The rates of LBW, PTB and SGA were, 11.5%, 17.1% and 32.8% in the DRC and 15.9%, 10.5% and 20.1% in SA. SES factors differed between countries and sex. In the DRC, being married decreased the odds of having LBW and PTB children by 86% and 80%, respectively. In SA, being a mother with secondary level of education and above was associated with 86% reduced odds of SGA. In the pooled analyses, women with secondary level of education and above had a 2.2-fold increase in odds of giving birth to a PTB newborn. Country of residence and maternal nutritional status were stronger predictors of birth outcomes than SES factors. CONCLUSION FOR PRACTICE In sub-Saharan Africa, policies aiming to alleviate women's education combined with improved social support and household SES prior to and during pregnancy are critical to optimal neonatal outcomes and strategic to achieve the Sustainable Development Goals.

Abstract
OBJECTIVE Using data compiled by the SALURBAL project (Urban Health in Latin America; 'Salud Urbana en América Latina') we quantified variability in low birth weight (LBW) across cities in Latin America, and evaluated the associations of socio-economic characteristics at various levels (maternal, sub-city and city) with the prevalence of LBW. METHODS The sample included 8 countries, 360 cities, 1321 administrative areas within cities (sub-city units) and birth registers of more than 4.5 million births for the year 2014. We linked maternal education from birth registers to data on socioeconomic characteristics of sub-cities and cities using the closest available national population census in each country. We applied linear and Poisson random-intercept multilevel models for aggregated data. RESULTS The median prevalence of city LBW by country ranged from a high of 13% in Guatemala to a low of 5% in Peru (median across all cities was 7.8%). Most of the LBW variability across sub-cities was between countries, but there were also significant proportions between cities within a country, and within cities. Low maternal education was associated with higher prevalence of LBW (Prevalence rate ratios (PRR) for less than primary vs. completed secondary or more 1.12 95% CI 1.10, 1.13) in the fully adjusted model. In contrast, higher sub-city education and a better city social environment index were independently associated with higher LBW prevalence after adjustment for maternal education and age, city population size and city gross domestic product (PRR 1.04 95% CI 1.03, 1.04 per SD higher sub-city education and PRR 1.02 95% CI 1.00, 1.04 per SD higher SEI). Larger city size was associated with a higher prevalence of LBW (PRR 1.06; 95% CI 1.01, 1.12). CONCLUSION Our findings highlight the presence of heterogeneity in the distribution of LBW and the importance of maternal education, local and broader social environments in shaping LBW in urban settings of Latin America. Implementing context-sensitive interventions guided to improve women's education is recommended to tackle LBW in the region.

Abstract
BACKGROUND In Australia, 6.7% of babies (5.2% for singletons) are born low birth weight (LBW), and over the past decade, this figure has increased by 8%. Evidence regarding LBW has largely come from hospital-based cross-sectional studies, which are not representative, lack temporality and do not examine the potential predictors of LBW using a comprehensive theoretical framework. This study, therefore, examined predictors of LBW within a biopsychosocial framework, using a community-based representative prospective cohort with 19 years of data. METHODS The study included 11 854 singleton babies born to 5622 women from the 1973 to 1978 cohort of the Australian Longitudinal Study on Women's Health. RESULTS Among 5622 first births, 310 (5.5%) were reported as LBW. Maternal risk factors included pre-pregnancy underweight (aOR = 2.27, 95% CI: 1.43-3.62), chronic diabetes (aOR = 2.38, 95% CI: 1.14-4.95), gestational diabetes (aOR = 1.93, 95% CI: 1.27-2.94), chronic hypertension (aOR = 2.23, 95% CI: 1.50-3.33) and gestational hypertension (aOR = 2.44, 95% CI: 1.78-3.36). Among all births (N = 11 854), the overall LBW rate was 3.8% with a recurrence rate of 4.8%. Identified risk factors included menarche before 12 years (aOR = 1.57; 95% CI: 1.17-2.11), pre-pregnancy underweight (aOR = 2.25, 95% CI: 1.46-3.45), gestational diabetes (aOR = 1.74, 95% CI: 1.16-2.59), chronic hypertension (aOR = 2.01, 95% CI: 1.40-2.90) and gestational hypertension (aOR = 2.81, 95% CI: 2.05-3.84). LBW was less likely for second births (aOR = 0.39, 95% CI: 0.31-0.50) and third/above births (aOR = 0.49, 95% CI: 0.35-0.67) compared with the first births. CONCLUSION Increased nutrition counselling/supplementation for underweight women and interventions aimed at chronic disease prevention and management by using a multi-sectoral approach may be the key to the prevention of LBW.

Abstract
Necrotizing enterocolitis (NEC) is a serious disease of the intestinal tract affecting 5-10% of pre-term infants with up to 50% mortality in those that require surgery. There is wide variation in the rates and outcomes of NEC by race and ethnicity, and the reasons for this disparity are poorly understood. In this article, we review the epidemiology and discuss possible explanations for racial and ethnic differences in NEC. Most of the current evidence investigating the role of race in NEC comes from North America and suggests that Hispanic ethnicity and non-Hispanic Black race are associated with higher risk of NEC compared to non-Hispanic White populations. Differences in pre-term births, breastfeeding rates, and various sociodemographic factors does not fully account for the observed disparities in NEC incidence and outcomes. While genetic studies are beginning to identify candidate genes that may increase or decrease risk for NEC among racial populations, current data remain limited by small sample sizes and lack of validation. Complex interactions between social and biological determinants likely underly the differences in NEC outcomes among racial groups. Larger datasets with detailed social, phenotypic, and genotypic information, coupled with advanced bioinformatics techniques are needed to comprehensively understand racial disparities in NEC.

Abstract
Background: In Europe, about 76% of cases of chromosomal anomalies are prenatally diagnosed. Prenatal diagnosis allows more efficient planning of postnatal treatment and helps parents for an informed decision about the continuation of pregnancy. The main aim of this study was to evaluate whether the sociodemographic maternal characteristics affect the probability of prenatal diagnosis of chromosomal anomalies. Methods: Cases of chromosomal anomalies in the period 2005-2017 came from the population-based registry of congenital anomalies of Tuscany (Italy). Differences in the proportion of cases prenatally diagnosed were investigated through the following maternal characteristics: education, geographic origin and occupation. The association between cases of termination of pregnancy after prenatal diagnosis and maternal characteristics was also analysed. Odds Ratios (OR) adjusted by maternal age were calculated using logistic regression models. Results were provided for all cases of chromosomal anomalies and for Down syndrome cases. Results: A total of 1,419 cases were included in the study. Cases prenatally diagnosed were 1,186 (83.6%). We observed a higher proportion of cases not prenatally diagnosed among cases with low maternal education compared to those with high maternal education (OR = 2.16, p < 0.001) and in women from high migratory outflow countries, compared to the Italian ones (OR = 2.85, p < 0.001). For prenatally diagnosed Down syndrome cases, we observed a higher proportion of termination of pregnancy for women with low education level (OR = 4.36, p = 0.023). Conclusions: In our study evidence of differences in the probability of prenatal diagnosis of chromosomal anomalies associated with maternal education and geographic origin was found. Population-based studies investigating sociodemographic disparities can provide essential information for targeted public health programs. Further studies are recommended to monitor the impact of the increasing availability of non-invasive screening tests.

Abstract
Antenatal care (ANC) aims of monitoring wellbeing of mother and foetus during pregnancy. We validate a set of indicators aimed of measuring the quality of ANC of women on low-risk, uncomplicated pregnancy through their relationship with maternal and neonatal outcomes. We conducted a population-based cohort study including 122,563 deliveries that occurred between 2015 and 2017 in the Lombardy Region, Italy. Promptness and appropriateness of number and timing of gynaecological visits, ultrasounds and laboratory tests were evaluated. We assessed several maternal and neonatal outcomes. Log-binomial regression models were used to estimate prevalence ratio (PR), and corresponding 95% confidence interval (95% CI), for the exposure→outcome association. Compared with women who adhered with recommendations, those who were no adherent had a significant higher prevalence of maternal intensive care units admission (PR: 3.1, 95%CI: 1.2-7.9; and 2.7, 1.1-7.0 respectively for promptness of gynaecological visits, and appropriateness of ultrasound examinations), low Apgar score (1.6, 1.1-1.2; 1.9, 1.3-2.7; and 2.1, 1.5-2.8 respectively for appropriateness and promptness of gynaecological visits, and appropriateness of ultrasound examinations), and low birth weight (1.8, 1.5-2.3 for appropriateness of laboratory test examinations). Benefits for mothers and newborn are expected from improving adherence to guidelines-driven recommendations regarding antenatal care even for low-risk, uncomplicated pregnancies.

Abstract
BACKGROUND Maternal race and socioeconomic status are predictors of obstetric morbidity and mortality in the U.S. A better understanding of the role that maternal education plays in these disparities could enable and target better interventions to improve obstetric outcomes. OBJECTIVE This study aims to assess the impact of the level of education on morbidity. STUDY DESIGN We conducted a retrospective nested cohort study from a multicenter observational cohort of women undergoing cesarean delivery. Nulliparous women with live, non-anomalous singleton gestations who underwent primary cesarean section and had education status recorded were included. Education level was categorized as none, elementary, high school, some college, and a college degree. The primary outcome was a composite of maternal cesarean complications including hysterectomy, uterine atony, blood transfusion, surgical injury, arterial ligation, infection, wound complication, and ileus. A composite of neonatal morbidity was evaluated as a secondary outcome. We then created a multivariable logistic regression model adjusting for selected demographic and obstetric variables that may influence the likelihood of the primary outcome. RESULTS 10,344 women met inclusion criteria with a 20.3% incidence of the primary outcome. After adjusting for potential confounding variables including race and medical co-morbidities, the incidence of maternal cesarean complications was found to be higher for women with only elementary (OR 1.34, 95% CI 1.01-1.78) and high school (OR 1.24, 95% CI 1.03-1.48) education, compared to women with a college degree. There was also higher neonatal morbidity among women with high school (OR 1.39, 95% CI 1.20-1.62) and some college (OR 1.23, 95% CI 1.04-1.46) education, compared to women with a college degree. CONCLUSION These findings suggest that efforts to alleviate adverse outcomes in obstetrics should target patient counseling and health literacy as differences in educational background are closely associated with disparities in maternal and neonatal morbidity.

Abstract
Objectives Socioeconomic status (SES) plays a conflicting role in preterm birth (PB). This study evaluated the association between SES and PB using, for the first time, a multidomain scale, validated for Saudi Arabia, with a scoring system and examined the effect of each SES domain on PB. The secondary outcome was to determine the effects of SES on birth weight (BW) and the subcategories of PB and BW. Methods This cross-sectional study was conducted between May 2017 and August 2017 at a National Guard tertiary center in Jeddah, Saudi Arabia. A total of 477 parents were interviewed using the Elzahrany R. SES scale. Results The rate of PB was 11.5%, with no significant differences among the high, middle, and low SES classes (13%, 11%, and 12.5%, respectively). There were no patients in the very low SES in this specific population. None of the maternal or neonatal characteristics were significantly different among SES classes except maternal age (p value = 0.03), and antenatal care recorded visits “booking” status (p value = 0.012). Stratified analysis for PB subcategories showed the lower SES classes had higher moderate (3.8%) and extreme (1.6%) PB. For BW subcategories, large for gestational age (LGA) infants were higher in the high SES class (13%). However, the lower SES classes had higher rates of lower BW. The association between SES and PB remained not significant after adjusting for the maternal age and antenatal booking status. Conclusion There was no association between SES and PB at a tertiary center providing universal care to the National Guard using multidomain socioeconomic determinants with a scoring system. However, lower SES was associated with lower BW. The use of the “polysocial risk score” based on locally validated surveys should be considered in any health research that examines the effects of socioeconomic determinants.

Abstract
Birth cohort studies are the most appropriate type of design to determine the causal relationship between potential risk factors during the prenatal or postnatal period and the health status of the newborn up to childhood and potentially adulthood. To date, there has been a growth in interest regarding observational population-based studies which are performed to provide answers to specific research questions for defined populations, for instance, assessing the exposure to environmental pollutants or drugs on the risk of developing a disease. Birth cohorts based on the recruitment and active follow-up of mothers and children allow the collection of biological material, and specific clinical and genetic information. However, they require a considerable amount of time and resources and, besides being usually of limited size, they are exposed to the risk of the loss of subjects to follow-up, with decreased statistical power and possible selection bias. For these reasons, linking the medical birth register with administrative health records for mothers and babies is increasingly being used in countries with a universal healthcare system, allowing researchers to identify large and unselected populations from birth, and to reconstruct relevant traits and care pathways of mothers and newborns. This Special Issue of the International Journal of Environmental Research and Public Health focuses on the current state of knowledge on perinatal and postnatal exposures and adverse pregnancy, maternal, fetal and neonatal outcomes through population-based birth cohort studies, with a specific focus on real-word data. The 12 accepted articles covered a wide range of themes that can be addressed specifically through birth cohort study design; however, only three were based on real word data with record-linkage to health administrative databases. In particular, two papers have addressed the topic of socioeconomic status considering several indicators both at the individual and contextual level. Two papers focused on inflammatory bowel diseases, both as an outcome of perinatal and antibiotic exposure in early life and as a condition associated with asthma, among children identified in a birth cohort based on a Regional Medical Birth Register. Three articles focused on medication use during pregnancy and its impact on maternal and fetal health. The effect of exposure to prenatal environmental risk factors on perinatal and childhood outcomes has been considered in two papers. Two papers analyzed ad hoc nationwide prospective birth cohorts set in Japan and UK. Finally, we included a systematic review with meta-analysis to evaluate the relation between growth restriction at birth and congenital heart defects. We think that this Special Issue may contribute to enriching the discussion of future challenges, opportunities, strengths and limitations for all research topics that can be investigated using a population-based birth cohort study design.

Abstract
IMPORTANCE Low socioeconomic status is associated with higher all-cause mortality and risks for aging-related diseases. Biological aging is a potential process underlying health conditions related to social disadvantages, which may be present from birth onward. OBJECTIVE To evaluate the association of parental socioeconomic status with telomere length (TL) at birth, a marker of biological aging. DESIGN, SETTING, AND PARTICIPANTS This prospective birth cohort study was conducted among 1504 mother-newborn pairs in Belgium recruited between February 1, 2010, and July 1, 2017. EXPOSURES Parental socioeconomic measures, including maternal educational level, occupation, paternal educational level, and neighborhood income based on median annual household income. MAIN OUTCOMES AND MEASURES Mean relative TL was measured in cord blood and placental tissue. By constructing a principal component, an integrative socioeconomic measure was derived that integrates parental socioeconomic status and neighborhood income. Multivariable adjusted regression analyses were performed to associate the integrative socioeconomic measure and TL at birth. RESULTS In 1026 newborns (517 boys; mean [SD] gestational age, 39.2 [1.4] weeks), a higher socioeconomic status was associated with longer cord blood TL and placental TL. Each unit increment in the integrative socioeconomic status measure was associated with 2.1% (95% CI, 0.9%-3.4%; P < .001) longer cord blood TL in boys, while no association was observed for girls (0.5% longer cord blood TL; 95% CI, -0.9% to 1.8%; P = .50). The sex-specific socioeconomic status interaction revealed a stronger association in boys compared with newborn girls (1.6%; 95% CI, 0.02%-3.3%; P = .047 for interaction). In placental tissue, higher socioeconomic status was associated with 1.8% (95% CI, 0.3%-3.3%; P = .02) longer TL in newborn boys but not in girls (0.4% longer TL; 95% CI, -1.2% to 2.0%; P = .63). For placental tissue, no sex and socioeconomic status interaction on TL was observed (1.4%; 95% CI, -0.5% to 3.4%; P = .16 for interaction). CONCLUSIONS AND RELEVANCE This study suggests that parental socioeconomic status is associated with newborn TL, especially in boys. The results indicate that familial social economic factors are associated with the potential cellular longevity of the next generation, with a potential higher transgenerational vulnerability for newborn boys.

Abstract
OBJECTIVE To analyse how the migration status of the child and young population is measured in the scientific literature on health and social inequalities in health in Europe. METHOD A systematic search of the literature published in Spanish, English and French between 2007 and 2017 in PubMed and Social Sciences Citation Index was carried out. The included studies analysed health and social inequalities in health of a population under 18 years old according to its migration origin in Europe. The variables used to measure the migration status were described. RESULTS 50 articles were included. Twenty studies analysed perinatal health, eleven mental health, nine dental health, and ten studies other variables. The main variables to define migration status were the country of birth (32 studies), either of the child, the mother, or one of the parents, and sometimes in a complementary way. Less frequent was the use of nationality (15 studies), of the child, or of the parents, especially the mother. Migration status is referred to in very different ways, not always comparable and sometimes the variable used is not clearly explained. CONCLUSIONS There is a great diversity of ways to measure migration status in the child and young population. A better definition and consensus is needed to improve the temporal and geographical comparability of knowledge in this area, which will help to design public policies aimed at reducing social inequalities in health from childhood.

Disparities of infant and neonatal mortality trends in Greece during the years of economic crisis by ethnicity, place of residence and human development index: a nationwide population study. BMJ Open 2019; 9:e025287. [PMID: 31427311 PMCID: PMC6701607 DOI: 10.1136/bmjopen-2018-025287] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/07/2018] [Revised: 05/30/2019] [Accepted: 07/02/2019] [Indexed: 01/09/2023] Open
Abstract
OBJECTIVE To study trends of infant mortality rate (IMR) and neonatal mortality rate in Greece during the period 2004-2016 and explore the role of sociodemographic factors in the years of crisis. DESIGN Nationwide individual data for live births and infant (0-11 months) deaths provided by the Hellenic Statistical Authority were examined using Poisson, joinpoint regression and interrupted time series (ITS) analyses. SETTING Greece. PARTICIPANTS All infant deaths (n=4862) over the 13-year period, of which 87.2% were born to Greek mothers, and respective live births. MAIN OUTCOME MEASURES Evolution of IMR (0-364 days), early (<7 days) neonatal mortality rate (ENMR), late (7-27 days) neonatal mortality rate (LNMR) and post neonatal (28-364 days) mortality rate (PNMR) trends, by maternal nationality, place of residence and Human Development Index (HDI). RESULTS By Poisson regression, overall, during the study period, among infants of Greek mothers, IMR and PNMR declined significantly (-0.9%; 95% CI -1.7% to -0.1% and -1.6%; -3.0% to -0.2% annually, respectively), although differentially by place of residence (IMRurban: -2.1%; -2.9% to -1.3%, IMRrural: +10.6%; 7.6% to 13.6%). By contrast, among infants of non-Greek mothers, the low starting IMR/ENMR/LNMR/PNMR increased significantly (max ENMR:+12.5%; 8.6% to 16.5%) leading to a non-significant time-trend pattern overall in Greece. The inverse associations of HDI with IMR, ENMR and PNMR were restricted to Greek mothers' infants. Joinpoint regression analyses among Greek mothers' infants indicated non-significant increasing trends of IMR and ENMR following the crisis (+9.3%, 2012-2016, p=0.07 and +10.2%, 2011-2016, p=0.06, respectively). By contrast, the high (+17.1%; 8.1% to 26.9%, p=0.002) IMR increases among non-Greek infants were restricted to 2004-2011 and equalised to those of Greek mothers' infants thereafter. ITS analyses in preset years (2008, 2010, 2012) identified significantly increasing trends in IMR, LNMR and PNMR after 2012, and in ENMR after 2010, among Greek mothers' infants. CONCLUSIONS HDI and rural residence were significantly associated with IMR. The strongly decreasing IMR trends among Greek-mothers' infants were stagnated after a lag time of ~4 years of crisis approximating the previously sharply increasing trends among non-Greeks.

ENVIRONMENT INTERNATIONAL 2019; 129:573-582. [PMID: 31174145 DOI: 10.1016/j.envint.2019.03.047] [Citation(s) in RCA: 37] [Impact Index Per Article: 7.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/09/2018] [Revised: 03/18/2019] [Accepted: 03/19/2019] [Indexed: 06/09/2023]
Abstract
BACKGROUND Per- and polyfluoroalkyl substances (PFASs) are widely used in China, but little is known about the association between prenatal PFASs exposure and fetal reproductive development as well as its potential mechanism. OBJECTIVE We investigated the effects of cord blood PFASs on fetal reproductive hormones and its potential mechanism in relation to steroidogenic enzymes. METHODS Ten selected PFASs (n = 351) including PFOS, PFOA, PFBS, PFDA, PFDoA, PFHpA, PFHxS, PFNA, PFOSA, and PFUA, and two reproductive hormones estradiol (E2) (n = 351) and testosterone (T) (n = 349) were measured in 351 cord blood serum samples from a Chinese birth cohort between 2010 and 2013. Three steroidogenic enzymes including P450arom (n = 125), 3β-HSD1 (n = 123), and 17β-HSD1 (n = 116) were measured in 125 placental tissue samples. Linear regression tested the associations between cord blood PFASs and reproductive hormones in cord blood. Mediation analysis assessed the role of placental steroidogenic enzymes between cord blood PFASs and reproductive hormones. RESULTS The positive associations between PFOA, PFHxS and E2 levels, PFOS, PFUA, PFNA and T levels, and PFOS, PFUA and T/E2 ratio were significant. PFUA, PFNA, PFDA, PFHxS, and ∑PFASs were associated with higher P450arom levels. PFHxS was also associated with increased 3β-HSD1 and 17β-HSD1 levels. These associations were more pronounced in females than males when stratified by gender. Furthermore, 17β-HSD1 demonstrated mediating effects in the positive association between cord blood PFHxS and E2 levels in females. CONCLUSION Our findings suggested the potential impacts of cord blood PFASs on fetal reproductive hormones, in which steroidogenic enzymes may play important roles. These associations were more pronounced in females than males.

Influence of vitamin D serum concentration, prenatal care and social determinants on birth weight: a northeastern Brazilian cohort study. Br J Nutr 2019; 122:284-292. [PMID: 31182171 DOI: 10.1017/s0007114519001004] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/24/2022]
Abstract
The relationship among social determinants, vitamin D serum concentration and the health and nutrition conditions is an important issue in the healthcare of pregnant women and newborns. Thus, the present study analyses how vitamin D, prenatal monitoring and social determinants are associated with birth weight. The cohort comprised 329 pregnant women, up to 34 weeks gestational age at the time of admission, who were receiving care through the prenatal services of Family Health Units. Structural equation modelling was used in the statistical analysis. The mean birth weight was 3340 (sd 0·545) g. Each nmol increase in maternal vitamin D serum concentration was associated with an increase in birth weight of 3·06 g. Prenatal healthcare with fewer appointments (β -41·49 g, 95 % CI -79·27, -3·71) and late onset of care in the second trimester or third trimester (β -39·24 g, 95 % CI -73·31, -5·16) favoured decreased birth weight. In addition, low socio-economic class and the practice of Afro-Brazilian religions showed a direct association with high vitamin D serum concentrations and an indirect association with high birth weight, respectively. High gestational BMI (β 23·84, 95 % CI 4·37, 43·31), maternal education level (β 24·52 g, 95 % CI 1·82, 47·23) and length of gestation (β 79·71, 95 % CI 52·81; 106·6) resulted in high birth weight. In conclusion, maternal vitamin D serum concentration, social determinants and prenatal care, evaluated in the context of primary healthcare, directly determined birth weight.

Uterine function, pregnancy complications, and pregnancy outcomes among female childhood cancer survivors. Fertil Steril 2019; 111:372-380. [PMID: 30691634 DOI: 10.1016/j.fertnstert.2018.10.016] [Citation(s) in RCA: 37] [Impact Index Per Article: 7.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2018] [Revised: 10/08/2018] [Accepted: 10/18/2018] [Indexed: 11/22/2022]
Abstract
OBJECTIVE To evaluate whether abdominal-pelvic radiotherapy for childhood cancer impairs uterine function and increases the risk of pregnancy complications and adverse pregnancy outcomes. DESIGN Nested cohort study. SETTING Not applicable. PATIENT(S) Childhood cancer survivors previously exposed to abdominal-pelvic radiotherapy (RT-exposed CCSs) as part of their treatment for childhood cancer. INTERVENTION(S) Radiotherapy-exposed CCSs (n = 55) were age- and parity-matched to nonirradiated CCSs (non-RT-exposed CCSs; n = 110) and general population controls (n = 110). MAIN OUTCOME MEASURES Uterine volume, pregnancy complications, and pregnancy outcomes. RESULT(S) Among nulligravidous participants, median (interquartile range) uterine volume was 41.4 (18.6-52.8) mL for RT-exposed CCSs, 48.1 (35.7-61.8) mL for non-RT-exposed CCSs, and 61.3 (49.1-75.5) mL for general population controls. Radiotherapy-exposed CCSs were at increased risk of a reduced uterine volume (<44.3 mL) compared with population controls (odds ratio [OR] 5.31 [95% confidence interval 1.98-14.23]). Surprisingly, the same was true for non-RT-exposed CCSs (OR 2.61 [1.16-5.91]). Among gravidous participants, RT-exposed CCSs had increased risks of pregnancy complications, preterm delivery, and a low birth weight infant compared with population controls (OR 12.70 [2.55-63.40], OR 9.74 [1.49-63.60], and OR 15.66 [1.43-171.35], respectively). Compared with non-RT-exposed CCSs, RT-exposed CCSs were at increased risk of delivering a low birth weight infant (OR 6.86 [1.08-43.75]). CONCLUSION(S) Uterine exposure to radiotherapy during childhood reduces adult uterine volume and leads to an increased risk of pregnancy complications and adverse pregnancy outcomes. Preconceptional counseling and appropriate obstetric monitoring is warranted.

Abstract
Objective Numerous studies established a link between socioeconomic status (SES) and several dimensions of general health. This study examines the association between maternal education as a widely used indicator of SES and outcome in newborns requiring surgical correction of congenital anomalies. Methods Ambispective data analysis of newborns with esophageal atresia (EA), intestinal atresia (IA), congenital diaphragmatic hernia (CDH), omphalocele (OC), gastroschisis (GS) undergoing surgery between 01/2008-11/2017 accessing the clinical databases Neodat and Viewpoint. Maternal education was determined according to the validated education classification CASMIN and stratified into “low” SES and “high” SES group. Endpoints were incidence of postoperative complications, length of mechanical ventilation, and readmission to NICU. Results Inclusion of 169 patients with EA (n = 32), IA (n = 24), CDH (n = 47), OC (n = 19), GS (n = 47). Women of low SES (n = 67, 40%) attended fewer prenatal screenings (total, 4.6 vs. 7.9, P<0.0001; EA, 3.7 vs. 7.1, P = 0.0002; IA, 3.5 vs. 9.4, P = 0.0006; OC, 2.5 vs. 8.8, P = 0.009; GS, 4.1 vs. 7.0, P = 0.002). Low SES was associated with higher incidence of patients born small for gestational age (37% vs. 20%, P = 0.019), with additional congenital malformations (37% vs. 15%, P = 0.001), being born in a peripheral center (7% vs. 0%, P = 0.008), and with higher incidence of 5´APGAR scores <7 (23% vs. 7%, P = 0.004). Moreover, low SES was associated with higher incidence of postoperative complications (total 70% vs. 32%, P<0.0001; EA, 60% vs. 23%, P = 0.04; IA, 67% vs. 11%, P = 0.008; CDH, 83% vs. 46%, P = 0.009; GS, 74% vs. 25%, P = 0.001), and higher readmission rate to NICU (IA, 33% vs. 0%, P = 0.043; GS, 32% vs. 4%, P = 0.007). Conclusions Low maternal education is associated with a reduced uptake of prenatal screenings, adverse neonatal outcomes, and higher incidence of postoperative complications in newborns with congenital anomalies. Primary prevention and specific support should be provided prenatally for families with low SES to avoid adverse outcomes.

Singleton pregnancies after in vitro fertilization in Estonia: a register-based study of complications and adverse outcomes in relation to the maternal socio-demographic background. BMC Pregnancy Childbirth 2019; 19:51. [PMID: 30696425 PMCID: PMC6352442 DOI: 10.1186/s12884-019-2194-x] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2018] [Accepted: 01/16/2019] [Indexed: 12/18/2022] Open
Abstract
Background An increased risk of adverse conditions related to in vitro fertilization (IVF) pregnancies has been repeatedly reported. Our study aimed to summarize outcome differences between pregnancies after IVF and after spontaneous conception (SC) in Estonia. Methods Data on all liveborn singletons to primiparas women aged 25–40 years during the period 2005–2014 were obtained from the Estonian Medical Birth Registry. There were 1778 and 33,555 newborns in the IVF and SC cohort, respectively. The relative risk of pregnancy-related complications and adverse pregnancy outcomes in the IVF cohort in comparison with the SC cohort was quantified by prevalence proportion ratios (RR) with 95% confidence intervals (CI) using modified Poisson regression models adjusted for maternal age, education, ethnicity, marital status and study period. Results The cohort of IVF singletons experienced a higher risk of preterm birth (RR 1.51; 95% CI 1.28–1.78), iatrogenic preterm birth (RR 1.62; 95% CI 1.32–1.98), very preterm birth (RR 1.49; 95% CI 1.00–2.23), low birthweight (RR 1.47; 95% CI 1.20–1.80), congenital anomalies (RR 1.51; 95% CI 1.08–2.11), and admission to a neonatal intensive care unit (RR 1.13; 95% CI 1.01–1.26). Somewhat elevated risk of spontaneous preterm birth did not reach statistical significance (RR 1.32; 95% CI 0.97–1.80). IVF mothers were at increased risk of placenta previa (RR 7.15; 95% CI 4.04–12.66), placental abruption (RR 2.12; 1.43–3.14) and cesarean section (RR 1.28; 95% CI 1.20–1.37). The risk of pre-eclampsia was borderline (RR 1.25; 95% CI 0.98–1.59). Adjustment for maternal age attenuated the associations between IVF and adverse outcomes. Maternal education, ethnicity and marital status had no effect on the magnitude of the risk estimates. Conclusions The increased risk of pregnancy-related complications and adverse pregnancy outcomes was observed in the Estonian cohort of IVF singletons in comparison with the cohort of SC singletons. The relative risk estimates grew with maternal age but were not influenced by the maternal education, ethnicity and marital status. To monitor the efficacy and safety of the used assisted reproductive technology, a specialized country-wide register should be created in Estonia.
