Lundborg L, Joseph KS, Lisonkova S, Chan WS, Wen Q, Ananth CV, Razaz N. Temporal changes in pre-existing health conditions five years prior to pregnancy in British Columbia, Canada, 2000-2019. Paediatr Perinat Epidemiol 2024; 38:383-393. [PMID: 38366741 DOI: 10.1111/ppe.13060] [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: 09/06/2023] [Revised: 01/30/2024] [Accepted: 02/07/2024] [Indexed: 02/18/2024]
Abstract
BACKGROUND Pre-existing health conditions increase the risk of obstetric complications during pregnancy and birth. However, the prevalence and recent changes in the frequency of pre-existing health conditions in the childbearing population remain unknown. OBJECTIVES To estimate the temporal changes in the prevalence of pre-existing health conditions among pregnant women in British Columbia, Canada. METHODS We carried out a population-based cross-sectional study of 825,203 deliveries in BC between 2000 and 2019 and examined 17 categories of physical and psychiatric health conditions recorded within 5 years before childbirth. We also undertook age-period-cohort analyses to evaluate temporal changes in pre-existing health conditions. RESULTS The prevalence of any pre-existing health condition was 26.2% (n = 216,214) with overall trends remaining stable during the study period. Between 2000 and 2019, the prevalence rates of anxiety (5.6%-9.6%), bipolar (1.6%-3.4%), psychosis (0.7%-0.8%), and eating disorders (0.2%-0.3%) increased. The prevalence of hypertension increased sharply from 0.06% in 2000 to 0.3% in 2019. Diabetes mellitus and stroke rates increased, as did the prevalence of systemic lupus, multiple sclerosis, and chronic kidney disease. Advanced maternal age was strongly associated with both psychiatric and circulatory/metabolic conditions. A strong birth cohort effect was evident, with rates of psychiatric conditions increasing among women born after 1985. CONCLUSIONS In British Columbia, Canada, 1 in 4 mothers had a pre-existing health condition 5 years prior to pregnancy. These findings underscore the need for multi-disciplinary care for women with pre-existing health conditions to improve maternal, foetal, and infant health.

Abstract
Objective To identify independent risk factors for placenta accreta spectrum among pregnancies conceived with assisted reproductive technology. Design Retrospective cohort study. Setting Tertiary hospital. Patients Individuals who conceived with assisted reproductive technology and reached 20 weeks' gestation or later from 2011 to 2017. Interventions Patient and cycle data was abstracted from hospital records and supplemented with state-level data. Poisson regression was used for multivariate analyses and reported as adjusted relative risks (aRR). Main Outcome Measures Clinical or histologic placenta accreta spectrum. Results Of 1,975 qualifying pregnancies, 44 (2.3%) met criteria for accreta spectrum at delivery. In the multivariate model, significant risk factors included low-lying placenta at delivery (aRR, 15.44; 95% CI 7.76-30.72), uterine factor infertility or prior uterine surgery (aRR, 4.68; 95% CI, 2.72-8.05), initial low-lying placentation that resolved (aRR, 3.83; 95% CI, 1.90-7.73), and use of frozen embryos (aRR, 3.02; 95% CI, 1.66-5.48). When the fresh vs frozen variable was replaced with controlled ovarian hyperstimulation, the final model did not change (aRR, 2.40 for unstimulated cycles, 95% CI, 1.32-4.38). With frozen transfers, the accreta rate was 16% when the endometrial thickness was < 6mm vs 3.8% with thicker endometrium (P=.02). Conclusions Among pregnancies conceived with assisted reproductive technology, accreta spectrum is associated with low placental implantation (even when resolved), uterine factor infertility and prior uterine surgery, and the use of frozen embryo transfer or unstimulated cycles.

Iranian women's attitude toward childbearing and its' association with generalized trust, social support, marital satisfaction and governmental childbearing incentives. Heliyon 2023; 9:e16162. [PMID: 37215895 PMCID: PMC10199260 DOI: 10.1016/j.heliyon.2023.e16162] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2023] [Revised: 04/27/2023] [Accepted: 05/09/2023] [Indexed: 05/24/2023] Open
Abstract
Background Having a child is important event for families worldwide. Attitudes toward childbearing are influenced by many factors. The aim of the present study was to investigate Iranian women's attitude toward childbearing and its association with generalized trust, social support, marital satisfaction, mental health, and socio-economic characteristics in Qazvin province. Methods A cross-sectional survey study was conducted between April and July 2022. Using convenience sampling, 347 women with no children or one child in Qazvin province (Iran) participated in the study. Data were collected via the Iranian online platform Porsline. The survey included a demographic and fertility characteristics questionnaire, Attitudes Toward the Government's Childbearing Incentives Scale (ATGCIS), Attitudes Toward Fertility and Childbearing Scale (ATFCS), ENRICH Marital Satisfaction Scale (ENRICH MSS), Patient Health Questionnaire (PHQ-4), Multidimensional Scale of Perceived Social Support (MSPSS), and Generalized Trust Scale (GTS). Findings The average age of participants was 35.66 years (SD = 6.89). The score of attitudes toward fertility and childbearing was 84.66 out of 134 (SD = 19.17). The average number of expected children by the couple was 2.36 (SD = 1.35). Multivariable linear regression found a positive and significant relationship between participants' attitudes toward fertility and childbearing (ATFC) and (i) governmental childbearing incentives (β = 0.365, p < 0.001, with 1.37 increase in ATFC with each unit increase in this scale) (ii) generalized trust (i.e., individual's expectation of others' trustworthiness), (β = 0.155, p < 0.003, with 0.60 increase in ATFC with each unit increase in generalized trust) and (iii) marital satisfaction (β = 0.146, p < 0.005, with 0.26 increase in ATFC with each unit increase marital satisfaction). The multivariable linear regression model also showed that attitudes toward fertility and childbearing was the only predictor of couples' expected number of children in the future (β = 0.214, p < 0.001, with 0.38 increase in couples' expected number of children with each unit increase in ATFC). Conclusion Government incentives were the strongest independent predictor of participants' attitudes toward childbearing which can indirectly influence couples' expected number of children in the future. Consequently, governments may be able to influence couples' childbearing decisions by providing appropriate incentives. Generalized trust and marital satisfaction were other significant predictors of attitudes toward childbearing. Therefore, implementing programs to improve generalized trust, and increasing marital satisfaction might be other influential measures in couples' childbearing decisions.

Abstract
Background: The increasing prevalence of preexisting health conditions among pregnant people is often attributed to the concurrent rise in maternal age. However, the link between advanced maternal age (AMA) and increases in chronic conditions among the birthing population has not been systematically documented at the population level. Materials and Methods: This retrospective population-based cohort study was based on linked hospitalization discharge and birth certificate data for live birth deliveries in California from 1991 to 2012. Decomposition techniques evaluated whether changes in the prevalence of selected preexisting health conditions during delivery (autoimmune conditions, chronic hypertension, cardiac disease, diabetes, and renal disease) were explained by population-level increases in maternal age. Analyses further adjusted for maternal education, plurality, insurance status, and availability of paternal information on the birth certificate. Results: Between 1991 and 2012, there were more than 11.5 million live birth deliveries in California. AMA (≥35 years) increased nearly 70% over this period. The prevalence of autoimmune conditions, chronic hypertension, diabetes, and renal disease rose among the birthing population, while cardiac disease declined. The prevalence of all conditions was higher for AMA, but changes in maternal age accounted for only 5.3%, 8.4%, 13.9%, and 0.4%, of the increase in autoimmune conditions, chronic hypertension, diabetes, and renal disease, respectively. Conclusion: While AMA was associated with higher rates of preexisting health conditions, it contributed little to the increase in autoimmune conditions, chronic hypertension, and diabetes and nothing to the rise in renal disease during childbirth.

Abstract
BACKGROUND Although there is a significant body of evidence on maternal mental health, an inadequate focus has been placed on African immigrant women. This is a significant limitation given the rapidly changing demographics in Canada. The prevalence of maternal depression and anxiety among African immigrant women in Alberta and Canada, as well as the associated risk factors, are not well understood and remain largely unknown. OBJECTIVE The purpose of this study was to investigate the prevalence and associated factors of maternal depression and anxiety among African immigrant women living in Alberta, Canada up to 2 years postpartum. METHODS This cross-sectional study surveyed 120 African immigrant women within 2 years of delivery in Alberta, Canada from January 2020 to December 2020. The English version of the Edinburgh Postnatal Depression Scale-10 (EPDS-10), the Generalized Anxiety Disorder-7 (GAD-7) scale, and a structured questionnaire regarding associated factors were administered to all participants. A cutoff score of 13 on the EPDS-10 was indicative of depression, while a cutoff score of 10 on the GAD-7 scale was indicative of anxiety. Multivariable logistic regression was used to determine the factors significantly associated with maternal depression and anxiety. RESULTS Among the 120 African immigrant women, 27.5% (33/120) met the EPDS-10 cutoff score for depression and 12.1% (14/116) met the GAD-7 cutoff score for anxiety. The majority of respondents with maternal depression were younger (18/33, 56%), had a total household income of CAD $60,000 or more (US $45,000 or more; 21/32, 66%), rented their homes (24/33, 73%), had an advanced degree (19/33, 58%), were married (26/31, 84%), were recent immigrants (19/30, 63%), had friends in the city (21/31, 68%), had a weak sense of belonging in the local community (26/31, 84%), were satisfied with their settlement process (17/28, 61%), and had access to a regular medical doctor (20/29, 69%). In addition, the majority of respondents with maternal anxiety were nonrecent immigrants (9/14, 64%), had friends in the city (8/13, 62%), had a weak sense of belonging in the local community (12/13, 92%), and had access to a regular medical doctor (7/12, 58%). The multivariable logistic regression model identified demographic and social factors significantly associated with maternal depression (maternal age, working status, presence of friends in the city, and access to a regular medical doctor) and maternal anxiety (access to a regular medical doctor and sense of belonging in the local community). CONCLUSIONS Social support and community belonging initiatives may improve the maternal mental health outcomes of African immigrant women. Given the complexities immigrant women face, more research is needed on a comprehensive approach for public health and preventive strategies regarding maternal mental health after migration, including increasing access to family doctors.

Abstract
OBJECTIVE To investigate the association between a mother's age and the risk of caesarean section (CS) when controlling for health factors and selected sociodemographic characteristics. METHODS Binary logistic regression models for all women who gave birth in Czechia in 2018 (N = 111,749 mothers who gave birth to 113,234 children). RESULTS An increase in the age of a mother significantly increases the odds of a CS birth according to all of the models; depending on the model, OR: 1.62 (95% CI 1.54-1.71) to 1.84 (95% CI 1.70-1.99) for age group 35-39 and OR: 2.83 (95% CI 2.60-3.08) to 3.71 (95% CI 3.23-4.27) for age group 40+ compared to age group 25-29. This strong association between the age of a mother and the risk of CS is further reinforced for primiparas (probability of a CS: 11% for age category ≤ 19, 23% for age category 35-39, and 38% for age category 40+). However, the increasing educational attainment of young women appears to have weakened the influence of increasing maternal age on the overall share of CS births; depending on the model, OR: 0.86 (95% CI 0.80-0.91) to 0.87 (95% CI 0.83-0.91) for tertiary-educated compared to secondary-educated women. CONCLUSIONS The age of a mother comprises an independent risk factor for a CS birth when the influence of health, socioeconomic, and demographic characteristics is considered.

Abstract
OBJECTIVE To define specific risk factors for placenta previa in pregnancies conceived with assisted reproductive technology (ART). DESIGN Retrospective cohort. SETTING Fertility centers and inpatient obstetric units in Massachusetts. PATIENT(S) Patients conceiving with ART and delivering at 20 weeks gestation or later between 2011 and 2017 in Massachusetts. INTERVENTION(S) Patient demographic and medical factors and specific components of their cycles. Data were obtained by linking vital records of the State of Massachusetts to reproductive clinic data obtained from the Society for Assisted Reproductive Technology Clinic Outcome Reporting System, and then supplementing this information with laboratory and obstetric data from 2 large academic hospitals. MAIN OUTCOME MEASURE Associations were tested between multiple cycle- and patient-related factors and placenta previa or low-lying placenta at delivery. After testing for confounders, multivariate models were adjusted for maternal age, history of prior cesarean delivery and birth plurality, and are reported as adjusted relative risks (aRR). RESULT(S) We included 18,939 pregnancies, with 553 (2.9%) having placenta previa at delivery. Advanced maternal age (aRR, 1.25; 95% confidence interval [CI], 1.06-1.48), endometriosis, (aRR, 2.22; 95% CI, 1.71-2.86), and controlled ovarian hyperstimulation (aRR, 1.33; 95% CI, 1.12-1.59) were associated with placenta previa, whereas multiple births (aRR, 0.63; 95% CI, 0.48-0.81) and a history of polycystic ovary syndrome or ovulation disorders (aRR, 0.59; 95% CI, 0.46-0.75) had negative associations. The endometriosis association was strong in nulliparas and the controlled ovarian hyperstimulation association was strong in parous patients in a stratified analysis. No association was seen with prior history of cesarean delivery. CONCLUSION(S) Patients conceiving with ART do not have the typical previa risk factors of prior cesarean delivery and multiple gestations, whereas endometriosis and fresh embryo transfers contributed moderate risk. The embryo transfer process itself may affect previa development in this population.

Crude and adjusted comparisons of cesarean delivery rates using the Robson classification: A population-based cohort study in Canada and Sweden, 2004 to 2016. PLoS Med 2022; 19:e1004077. [PMID: 35913981 PMCID: PMC9377587 DOI: 10.1371/journal.pmed.1004077] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/20/2022] [Revised: 08/15/2022] [Accepted: 07/15/2022] [Indexed: 11/30/2022] Open
Abstract
BACKGROUND The Robson classification has become a global standard for comparing and monitoring cesarean delivery (CD) rates across populations and over time; however, this classification does not account for differences in important maternal, fetal, and obstetric practice factors known to impact CD rates. The objectives of our study were to identify subgroups of women contributing to differences in the CD rate in Sweden and British Columbia (BC), Canada using the Robson classification and to estimate the contribution of maternal, fetal/infant, and obstetric practice factors to differences in CD rates between countries and over time. METHODS AND FINDINGS We conducted a population-based cohort study of deliveries in Sweden (January 1, 2004 to December 31, 2016; n = 1,392,779) and BC (March 1, 2004 to April 31, 2017; n = 559,205). Deliveries were stratified into Robson categories and the CD rate, relative size of each group and its contribution to the overall CD rate were compared between the Swedish and the Canadian cohorts. Poisson and log-binomial regression were used to assess the contribution of maternal, fetal, and obstetric practice factors to spatiotemporal differences in Robson group-specific CD rates between Sweden and BC. Nulliparous women comprised 44.8% of the study population, while women of advanced maternal age (≥35 years) and women with overweight/obesity (≥25 kg/m2) constituted 23.5% and 32.4% of the study population, respectively. The CD rate in Sweden was stable at approximately 17.0% from 2004 to 2016 (p for trend = 0.10), while the CD rate increased in BC from 29.4% to 33.9% (p for trend < 0.001). Differences in CD rates between Sweden and BC varied by Robson group, for example, in Group 1 (nullipara with a term, single, cephalic fetus with spontaneous labor), the CD rate was 8.1% in Sweden and 20.4% in BC (rate ratio [RR] for BC versus Sweden = 2.52, 95% confidence interval [CI] 2.49 to 2.56, p < 0.001) and in Group 2 (nullipara, single, cephalic fetus, term gestation with induction of labor or prelabor CD), the rate of CD was 37.3% in Sweden and 45.9% in BC (RR = 1.23, 95% CI 1.22 to 1.25, p < 0.001). The effect of adjustment for maternal characteristics (e.g., age, body mass index), maternal comorbidity (e.g., preeclampsia), fetal characteristics (e.g., head position), and obstetric practice factors (e.g., epidural) ranged from no effect (e.g., among breech deliveries; Groups 6 and 7) to explaining up to 5.2% of the absolute difference in the CD rate (Group 2: adjusted CD rate in BC 40.7%, adjusted RR = 1.09, 95% CI 1.08 to 1.12, p < 0.001). Adjustment also explained a substantial fraction of the temporal change in CD rates among some Robson groups in BC. Limitations of the study include a lack of information on intrapartum details, such as labor duration as well as maternal and perinatal outcomes associated with the observed differences in CD rates. CONCLUSIONS In this study, we found that several factors not included in the Robson classification explain a significant proportion of the spatiotemporal difference in CD rates in some Robson groups. These findings suggest that incorporating these factors into explanatory models using the Robson classification may be useful for ensuring that public health initiatives regarding CD rates are evidence informed.

The trend in delayed childbearing and its potential consequences on pregnancy outcomes: a single center 9-years retrospective cohort study in Hubei, China. BMC Pregnancy Childbirth 2022; 22:514. [PMID: 35751047 PMCID: PMC9233367 DOI: 10.1186/s12884-022-04807-8] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2021] [Accepted: 06/02/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Due to the advancement of modern societies, the proportion of women who delay childbearing until or beyond 30 years has dramatically increased in the last three decades and has been linked with adverse maternal-neonatal outcomes. OBJECTIVE To determine the trend in delayed childbearing and its negative impact on pregnancy outcomes. MATERIAL AND METHODS A tertiary hospital-based retrospective study was conducted in Wuhan University Renmin Hospital, Hubei Province, China, during the years 2011-2019. The joinpoint regression analysis was used to find a trend in the delayed childbearing and the multiple binary logistic regression model was used to estimate the association between maternal age and pregnancy outcomes. RESULTS Between 2011 and 2019, the trend in advanced maternal age (AMA ≥35 years) increased by 75% [AAPC 7.5% (95% CI: - 10.3, 28.9)]. Based on maternal education and occupation, trend in AMA increased by 130% [AAPC 11.8% (95% CI: 1.1, 23.7)] in women of higher education level, and 112.5% [AAPC 10.1% (95% CI: 9.4, 10.9)] in women of professional services. After adjusting for confounding factors, AMA was significantly associated with increased risk of gestational hypertension (aOR 1.5; 95% CI: 1.2, 2.1), preeclampsia (aOR 1.6; 95% CI: 1.4, 1.9), sever preeclampsia (aOR 1.7; 95% CI: 1.1, 2.6), placenta previa (aOR 1.8; 95% CI: 1.5, 2.2), gestational diabetes mellitus (aOR 2.5; 95% CI: 2.3, 2.9), preterm births (aOR 1.6; 95% CI: 1.4, 1.7), perinatal mortality (aOR 1.8; 95% CI: 1.3, 2.3), and low birth weight (aOR 1.3; 95% CI: 1.2, 1.4) compared with women aged < 30 years. CONCLUSION Our findings show a marked increase in delayed childbearing and its negative association with pregnancy outcomes.

Advanced Maternal Age and Its Association With Cardiovascular Disease in Later Life. Womens Health Issues 2022; 32:219-225. [PMID: 35058125 DOI: 10.1016/j.whi.2021.12.007] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2021] [Revised: 12/10/2021] [Accepted: 12/17/2021] [Indexed: 12/23/2022]
Abstract
INTRODUCTION Fertility among women at advanced maternal age (AMA) is increasing at a rapid rate in the United States. Although much is known about the impact of older maternal age on the risk for proximate adverse pregnancy outcomes, it is unclear whether older maternal age affects subsequent health. The objective of this study was to evaluate whether AMA is associated with cardiovascular disease (CVD) later in life, adjusting for important social and health factors related to maternal age. METHODS Data were obtained from the Nurses' Health Study II, a longitudinal prospective cohort study. We investigated whether women with an AMA first or subsequent birth were at higher risk for developing CVD (myocardial infarction or stroke) after age 42 than women without births at AMA. Cox proportional hazard models were estimated to evaluate this association, adjusting for demographic, fertility, and health characteristics. RESULTS A total of 5,471 women (7.7%) in the sample had a first birth at an AMA and 1,282 (1.8%) developed CVD at age 42 or older. Women with first births at AMA had a 26% lower unadjusted hazard of CVD than women not at an AMA during their first birth (hazard ratio, 0.74; 95% confidence interval, 0.57-0.95). This association was attenuated (hazard ratio, 0.80; 95% confidence interval, 0.62-1.05) and no longer significant after adjustment for covariates; the modest association remained significant for women with any AMA birth. CONCLUSIONS We found no evidence that AMA births were associated with increased risk for developing CVD later in life in this sample.

Abstract
OBJECTIVE To investigate whether there is a specific maternal age cut-off at which there is an increase in maternal and neonatal adverse outcomes. METHODS A retrospective study comparing maternal and neonatal outcomes between nulliparous women of different ages. The receiver operating characteristic model with the Youden index was used to find the best age cut-off using cesarean delivery (CD) and composite adverse outcomes. A multivariable logistic regression analysis was calculated after adjusting for smoking, induction of labour, epidural use, hypertensive disorders, gestational diabetes, and birth weight. RESULTS The study included 11 343 nulliparous women. Age 28 years was found to be the cut-off age at which we found a significant increase in adverse outcomes. Women older than age 28 years had a higher risk of CD than women younger than 28 years (35.7% vs. 21.3%, P < 0.0001). They were also more likely to deliver prematurely (11.9% vs. 7.9%, P < 0.0001) and had higher rates hypertensive disorders (2.3% vs. 1.1%, P < 0.0001) and gestational diabetes mellitus (0.4% vs. 0.1%, P = 0.001). Furthermore, their babies were more likely to be growth restricted (1.1% vs. 0.3%, P < 0.0001). There were no differences in the rates of induction of labour or macrosomia. After adjusting for confounders, we found that women older than 28 years had higher risks of CD and adverse outcomes than younger women (aOR 1.9; 95% CI 1.744-2.1 and aOR 1.6; 95% CI 1.6-1.77, respectively). CONCLUSION Increasing maternal age is independently associated with adverse maternal and neonatal outcomes with an age cut-off of 28 years. Women older than age 28 years are at higher risk for composite adverse outcomes than younger women.

Abstract
Background: Approximately 10-20% of mothers have a chronic disease. Studies on breastfeeding in women with chronic disease span multiple disciplines, and these have not been collated to synthesize knowledge and identify gaps. The objective of this review was to summarize published literature on breastfeeding in women with chronic disease. Methods: We conducted a scoping review of original research and systematic reviews identified in Medline, EMBASE, and CINAHL (1990-2019) and by hand searching on women with chronic diseases reporting on at least one breastfeeding-related topic. Conference abstracts, case-studies, and studies on pregnancy-induced conditions or lactation pharmacology were excluded. Content analysis and narrative synthesis were used to analyze findings. Results: We identified 128 articles that were predominantly quantitative (80.5%), conducted in Europe or North America (65.6%), analyzed sample sizes of <200 (57.0%), and published from 2010 onward (68.8%). Diabetes (42.2%), multiple sclerosis (MS; 19.5%), and epilepsy (13.3%) were the most common diseases studied. Breastfeeding was a primary focus in approximately half (53.1%) of the articles, though definitions were infrequently reported (32.8%). The most-studied topics were breastfeeding duration/exclusivity (55.7%), reasons for feeding behavior (19.1%), and knowledge and attitudes about breastfeeding (18.3%). Less studied topics (<10% of articles each) included milk expression behaviors, breastfeeding difficulties, and feeding supports. Conclusions: Existing literature focuses primarily on diabetes or MS, and breastfeeding behaviors and outcomes. Further research examining a broader range of chronic diseases, with large sample sizes, and sufficient breastfeeding measurement detail can improve our understanding of breastfeeding disparities in this population.

Abstract
BACKGROUND Pregnancies in women over 35 years of age are becoming more frequent. The majority of studies point to an age of 35 as a provider of obstetric and neonatal complications. But several confounding factors are not taken into account and this results in contradictory results. METHODS The objective was to quantify the strength of the association between maternal age and obstetric and neonatal morbidity. This observational study was based on systematic records of 9 years of pregnancies managed in the Obstetrics and Gynaecology Department of Antoine Béclère Hospital, Clamart, France. In all, 24,674 pregnancies were managed at Antoine Béclère Hospital between April 1, 2007 and December 31, 2015, including 23,291 singleton pregnancies. Maternal age was the age at the beginning of pregnancy, taken as a quantitative variable. The main outcome measure was a composite "unfavourable" pregnancy outcome that included miscarriage, induced abortion, in utero foetal death, stillborn or newborn infant weighing under 500 g or delivered before 24 weeks of gestational age. Obstetric and neonatal morbidity comprised hospitalisation during pregnancy for more than 1 day, pre-eclampsia, gestational diabetes requiring hospitalisation, caesarean delivery, preterm birth, small-for-gestational age, and newborn transfer to the paediatric unit or neonatal intensive care unit. RESULTS Analyses were conducted among singleton pregnancies (n = 23,291) and were adjusted for obesity, assisted reproductive technology and geographical origin of the mother. Unfavourable pregnancy outcome rate tripled with age, from 5% among women aged 25 to 34 to 16% among those over 45. Women over 40 were twice as likely to be hospitalised as those aged 25 to 34. The caesarean section rate reached more than 40% among women over 40 and more than 60% in women over 45. The rate of newborn transfer to paediatric intensive care or a neonatal intensive care unit was doubled in women over 40 and small-for-gestational age was more frequent with age, reaching 34% in women over 45. CONCLUSIONS The risk of maternal-foetal complications increases steadily with age and is particularly high after 35 years and closer monitoring appears to be necessary. These results provide additional evidence and information for public health decision-makers.

Evidence around early induction of labor in women of advanced maternal age and those using assisted reproductive technology. Best Pract Res Clin Obstet Gynaecol 2021; 77:42-52.

Abstract
Worldwide, there has been a trend toward later motherhood. Concurrently, the incidence of subfertility has been on the rise, necessitating conception using assisted reproductive technologies (ARTs). These pregnancies are considered high risk due to fetal complications such as antepartum stillbirth and growth restriction and maternal complications such as increase in maternal morbidity and mortality. Early induction of labor can help to mitigate these risks. However, this has to be balanced against the iatrogenic harms of earlier delivery to both the baby, including respiratory distress and NICU stay, and the mother who might experience longer labor and other complications such as uterine hyperstimulation. Induction of labor at 39 weeks is the optimal timing for preventing antepartum stillbirth and avoiding iatrogenic harm. Delivery by elective cesarean section is not advocated as its benefits in these patients are unclear compared with the short- and long-term complications of a major abdominal surgery.

Abstract
Background Prenatal medical risk describes physical health issues or biological factors that predate or arise during pregnancy which heighten the risk of adverse outcomes, and often warrant specialized obstetric care. The influence of the nature and magnitude of prenatal risk on breastfeeding outcomes remains poorly understood. The objective of this study was to determine the association between prenatal medical risk and breastfeeding initiation and duration up to 1 year postpartum. Methods We analysed a subset of data from the All Our Families longitudinal cohort (n = 2706) of women in Calgary, Canada who delivered a liveborn infant between 2008 and 2010. Data were collected from self-report questionnaires and medical records. Women with complete data on prenatal medical risk factors and breastfeeding outcomes were included in this analysis. Prenatal medical risk was operationalized as one integer score of risk severity and four binary risk types capturing pre-pregnancy characteristics, past obstetric problems, current obstetric problems, and substance use. Outcomes were breastfeeding initiation defined as the infant ever receiving breast milk, and duration operationalized as still breastfeeding at 4 months, at 12 months, and time to breastfeeding cessation in weeks. We used logistic regression and Cox regression with right censoring at 52 weeks or attrition to calculate odds ratios (OR) and hazard ratios (HR), respectively, adjusting for sociodemographic vulnerability, parity, mode of delivery, and gestational age. Results Prenatal medical risk severity and type were not significantly associated with breastfeeding initiation, with the exception of pre-pregnancy risk type (OR 0.45; 95% CI 0.26, 0.77). Risk severity was associated with lower odds of breastfeeding to 4 months (OR 0.94; 95% CI 0.90, 0.99), 12 months (OR 0.93; 95% CI 0.87, 0.98), and earlier breastfeeding cessation (HR 1.05; 95% CI 1.02, 1.08). Associations with shorter breastfeeding length across the first postpartum year were observed for pre-pregnancy, current obstetric, and substance use risk types, but not past obstetric problems. Conclusion Prenatal medical risk is associated with shortened duration of breastfeeding. Women with prenatal medical risk may benefit from the proactive arrangement of lactation support before and following delivery to promote continued breastfeeding.

Abstract
ABSTRACT Age above 35 years at the time of birth is generally referred to as advanced maternal age (AMA), and it could be a risk factor for various complications besides genetic changes in the fetus. The primary outcome of this study was to determine if AMA is associated with emergent cesarean delivery (CD) following induction of labor (IOL). The secondary outcomes were a composite of adverse maternal and perinatal outcomes following IOL.This retrospective observational study included women with singleton, live-born, cephalic, non-anomalous pregnancies undergoing IOL from 38 0/7 to 41 6/7 weeks of gestation. Mode of delivery and other maternal and neonatal outcomes were compared between women aged ≥35 (AMA) and <35 years. Multivariate logistic regression analyses were performed.A total of 307 nulliparous women underwent IOL (≥35 years n = 73, 23.8%; <35 years n = 234, 76.2%) and among them, 252 (82.1%) delivered vaginally. The rate of CD was significantly higher in women of AMA (31.5% vs 13.7%, P = .001). Multivariable analysis showed that AMA was independently associated with CD (odds ratio 3.04, 95% confidence interval 1.55-5.96, P = .001). The rate of instrumental deliveries was higher in the AMA group (19.6% vs 8.2%, P = .043) and hemoglobin decrease during delivery was similar between the 2 groups (1.90 ± 1.25 vs 2.02 ± 1.27 mg/dL, all P > .05). Regarding neonatal outcomes, there was no difference between the 2 groups in the neonatal intensive care unit admission rate and Apgar score <7 at 5 minutes (30.3% vs 30.1% and 6.0% vs 8.2%, respectively, all P > .05). Neonatal intubation rate and severe respiratory problems were non-significantly higher in AMA (3.8% vs 2.7% and 3.4% vs 1.4%, respectively, all P > .05).AMA was associated with an approximately three-fold increased likelihood of birth by CD and operative vaginal delivery in uncomplicated nulliparous women following IOL. However, we found no evidence that IOL in primigravid women of AMA increases adverse maternal and perinatal outcomes as compared with women aged <35 years except the high prevalence of CD and operative vaginal delivery.

Abstract
OBJECTIVE This study aims to update the current reference for sex-specific birth weight percentiles by gestational age, overall and for specific ethnic groups, based on data from all singleton live-birth deliveries from 2005 to 2014 in Alberta, Canada. METHODS Infant and maternal information were captured in the Alberta Vital Statistics-Births Database for 473,115 singleton infants born to 311,800 women between January 1, 2005 and December 31, 2014. Within each sex, and each sex-ethnic group, birth weights were modelled by gestational age using generalized additive models and natural cubic splines. Crude and corrected estimates for birth weight percentiles including cut-off values for large for gestational age (LGA) and small for gestational age (SGA) were calculated by sex and sex-ethnic group, and gestational age for singleton live births. RESULTS LGA and SGA cut-offs were lower for females than for males for all gestational ages. The SGA and LGA percentiles were greater for both male and female very preterm infants in Alberta compared to previous national references. Ethnicity-specific LGA and SGA cut-offs for term Chinese and preterm and at-term South Asian infants were consistently lower than those for both the general population in Alberta and the previous national reference. South Asian infants had lower birth weights at almost all gestational ages compared with the other groups. CONCLUSION The updated birth weight percentiles presented in this study highlight the differences in SGA and LGA cut-offs among infants from South Asian, Chinese, and the general population, which may be important for clinical perinatal care.

Abstract
AbstractThe study aimed to determine the psychometric properties and factor structure of the Attitudes to Fertility and Childbearing Scale (AFCS) in a Polish context. A cross-sectional self-assessment study was conducted with a total group of 748 Polish women in two studies (n = 187 and n = 561, respectively). Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), using SEM were performed. A three-factor structure was extracted by the EFA; although it differed to that identified in the original studies, the CFA found it to be robust. The final Polish version of the AFCS consists of 26 statements, comprising three factors (Fertility and the child as an important value, Child as a barrier, and Personal awareness and responsibility concerning having a child), which have demonstrated satisfactory internal consistency. Although the original AFCS factor structure was not replicated, our findings demonstrate that the Polish adaptation of the Attitudes to Fertility and Childbearing Scale is a reliable and valid instrument for evaluating attitudes concerning fertility and childbearing in the Polish context.

Abstract
OBJECTIVES We aim to study the association of maternal age with maternal and neonatal complications in twin pregnancies. METHODS A retrospective cohort study of dichorionic-diamniotic twin pregnancies stratified into three groups according to maternal age ("A" <25, "B" 25-34 and "C" 35-44 years old). Outcome measures included pregnancy, delivery and neonatal complications. A sub-analysis of in vitro fertilization pregnancies only was conducted. RESULTS Compared with younger women (groups A [n=65] and B [n=783]), older women [group C (n=392)] demonstrated significantly higher rates of gestational diabetes mellitus (B 6.6% vs. A 0%, p =0.027, C 10.2% vs. B 6.6%, p =0.032), were more likely to undergo cesarean deliveries (C 66.6%, B 57.6%, A 52.3%, p =0.007), and were at increased risk of having more than 20% difference in weight between the twins (C 24.5%, B 17.4%, A 16.9%, p =0.013). Other outcomes, including preeclampsia, did not differ between the groups. A sub-analysis of the in vitro fertilization only pregnancies was performed. Compared with younger women (groups A [n=18] and B [n=388]), older women (group C [n=230]) underwent more cesarean deliveries (p=0.004), and had more than 20% difference in weight between the twins (p<0.004). Other outcomes, including gestational diabetes mellitus rates and preeclampsia, did not differ between the groups. CONCLUSIONS Women at advanced maternal age with dichorionic twin pregnancies had significantly higher rates of gestational diabetes mellitus, cesarean deliveries and fetal weight discordancy as compared with younger women. In contrast, the incidence of preeclampsia was not affected by maternal age.

Abstract
OBJECTIVE The objective of this study is to assess the impact of maternal age on neurodevelopmental (ND) outcomes of infants < 29 weeks gestational age (GA) at 18-24 months. STUDY DESIGN A retrospective cohort study of preterm infants < 29 weeks GA admitted to Canadian tertiary NICUs was performed. The primary outcome was a composite of death or ND impairment (NDI)/significant NDI (sNDI) at 18-24 months. Association between maternal age and outcome was assessed across maternal age groups (15-19, 20-34, 35-39 and ≥40 years) using logistic regression after adjusting for confounders. RESULTS Of 3691 eligible infants, 2652 with complete data were included in the analysis. Significant differences in maternal characteristics existed across age groups. The only difference in neonatal characteristics was the incidence of bronchopulmonary dysplasia (p < 0.01). There was no association between maternal age and death or NDI/sNDI after controlling for confounders. CONCLUSION Maternal age is not associated with differences in NDI/sNDI rates among Canadian preterm infants < 29 weeks GA.

Abstract
OBJECTIVE The study aimed to determine the outcome of babies born to women ≥40 years in a Jamaican birth cohort. PATIENTS AND METHODS Maternal demographic data and neonatal data for women ≥40 years who delivered live singleton babies and their younger counterparts aged 20 30 years were extracted from the JA KIDS birth cohort dataset. Outcome measures were preterm birth, low birth weight, very low birth weight, extremely low birth weight, macrosomia, a low 5-minute Apgar score <7, admission to the neonatal unit, and neonatal death. Descriptive analyses were performed; statistical significance was taken at the level p <0.05. RESULTS A total of 5,424 women and their babies were entered into the study, 5,099 (94%) women were aged 20 to 30 years (mean age ± standard deviation [SD]: 24.5 ± 3.2 years) and 325 (6%) were aged ≥40 years (mean age ± SD: 41.5 ± 1.6 years). A greater percentage of preterm babies (18%) were born to women ≥40 years than to their younger counterparts (14%; p = 0.04). There was no difference in the proportion of low birth weight infants, very low birth weight infants, or extremely low birth weight infants born between the two groups (p > 0.05). There was also no significant difference in the proportion of babies who were macrosomic and in those who had a low 5-minute Apgar score <7. There were 866 (16%) neonatal admissions, 67/325 (21%) of these babies were born to women aged ≥40 years and 799/5,099 (16%) were born to their younger counterparts (p = 0.01). The commonest reason for admission was prematurity. While 60 babies died, there was no significant difference between both groups with 56 (1%) born to women 20 to 30 years and 4 (1%) born to women ≥40 years (p = 0.48). CONCLUSION Adverse outcomes noted for babies born to women ≥40 years were prematurity and the need for neonatal admission. However, no excess mortality was recorded. KEY POINTS · Women 40 years and older are more likely to have a chronic illness such as hypertension and diabetes and to have an operative delivery.. · Babies born to women 40 years and older are more likely to be late premature infants and require neonatal admission.. · However, there is no increased risk of neonatal mortality..

Abstract
BACKGROUND Maternal age has progressively increased in industrialized countries. Most studies focus on the consequences of delayed motherhood for women's physical and mental health, but little is known about potential effects on infants' neurodevelopment. This prospective study examines the association between maternal age and offspring neurodevelopment in terms of both psychomotor development (Ages & Stages Questionnaires-3) and emotional competences (Early Childhood Behavior Questionnaire). METHODS We evaluated a cohort of healthy pregnant women aged 20-41 years and their offspring, assessed at 38 weeks gestation (n = 131) and 24 months after birth (n = 101). Potential age-related variables were considered (paternal age, education level, parity, social support, maternal cortisol levels, and maternal anxiety and depressive symptoms). Bayesian ordinal regression models were performed for each neurodevelopmental outcome. RESULTS Maternal age was negatively associated with poor child development in terms of personal-social skills [odds ratio (OR) -0.13, 95% confidence interval (CI) 0.77-0.99] and with difficult temperament in terms of worse emotional regulation (OR -0.13, 95% CI 0.78-0.96) and lower positive affect (OR 0.16, 95% CI 0.75-0.95). As for age-related variables, whereas maternal anxiety symptoms and cortisol levels were also correlated with poor child development and difficult temperament, maternal social support and parental educational level were associated with better psychomotor and emotional competences. CONCLUSION Increasing maternal age may be associated with child temperament difficulties and psychomotor delay in terms of social interaction skills. Early detection of neurodevelopment difficulties in these babies would allow preventive psychosocial interventions to avoid future neuropsychiatric disorders.

Abstract
Background To determine the effects of maternal age at first cesarean on maternal complications and adverse outcomes of pregnancy with the second cesarean. Methods This was a multicenter, historical, cross-sectional cohort study involving singleton pregnancies ≥28 gestational weeks, with a history of 1 cesarean delivery, and who underwent a second cesarean between January and December 2017 at 11 public tertiary hospitals in 7 provinces of China. We analyzed the effects of maternal age at first cesarean on adverse outcomes of pregnancy in the second cesarean using multivariate logistic regression analysis. Results The study consisted of 10,206 singleton pregnancies. Women were at first cesarean between 18 and 24, 25–29, 30–34, and ≥ 35 years of age; and numbered 2711, 5524, 1751, and 220 cases, respectively. Maternal age between 18 and 24 years at first cesarean increased the risk of placenta accreta spectrum (aOR, 1.499; 95% CI, 1.12–2.01), placenta previa (aOR, 1.349; 95% CI, 1.07–1.70), intrahepatic cholestasis of pregnancy (aOR, 1.947; 95% CI, 1.24–3.07), postpartum hemorrhage (aOR, 1.505; 95% CI, 1.05–2.16), and blood transfusion (aOR, 1.517; 95% CI, 1.21–1.91) in the second cesarean compared with the reference group (aged 25–29 years). In addition, maternal age ≥ 35 years at first cesarean was a risk factor for premature rupture of membranes (aOR, 1.556; 95% CI, 1.08–2.24), placental abruption (aOR, 6.464, 95% CI, 1.33–31.51), uterine rupture (aOR, 7.952; 95% CI, 1.43–44.10), puerperal infection (aOR, 6.864; 95% CI, 1.95–24.22), neonatal mild asphyxia (aOR, 4.339; 95% CI, 1.53–12.32), severe asphyxia (aOR, 18.439; 95% CI, 1.54–220.95), and admission to a neonatal intensive care unit (aOR, 2.825; 95% CI, 1.54–5.17) compared with the reference group (aged 25–29 years). Conclusions Maternal age between 18 and 24 years or advanced maternal age at first cesarean was an independent risk factor for adverse maternal outcomes with the second cesarean. Advanced maternal age at the first cesarean specifically increased adverse neonatal outcomes with the second. Therefore, decisions as to whether to perform a first cesarean at a young or advanced maternal age must be critically evaluated.

Abstract
BACKGROUND The Korean Pregnancy Outcome Study (KPOS) was established to investigate the determinants of adverse pregnancy outcomes among Korean women. METHODS We recruited 4,537 pregnant women between 2013 and 2017 from two tertiary centers located in Seoul, Korea, and a total of 4,195 Korean women met inclusion criteria in the baseline analysis. A range of data on socio-demographics, past medical histories, reproductive information, health-related behaviors, psychological health and clinical information were obtained using interviewer-based questionnaires and clinical assessment at 12, 24, and 36 gestational weeks (GW), delivery and 6-8 weeks postpartum. Blood samplings were performed at 12, 24 and 36 GW, and placental tissues were obtained after delivery. The main outcome of this study was pregnancy-related complications including gestational diabetes mellitus (GDM), gestational hypertension, and screening positive for peripartum depression. Depression was assessed using the Korean version of the Edinburgh Postnatal Depression Scale, and a score of ≥10 indicated a positive screen for depression. RESULTS Among 4,195 eligible pregnant women with a median age of 33.0 years, 3,565 (85.0%) pregnancy outcomes were available in this study, including 30 miscarriages, 16 stillbirths, and 3,519 deliveries. Mean gestational age was 38.8 GW, and mean birth weight was 3,236 gram. The prevalence of pregnancy complications of GDM, hypertensive disorders, and screening positive of depression during pregnancy and postpartum was 7.0%, 1.4%, 27.8%, and 16.6%, respectively. CONCLUSIONS We designed KPOS to identify the determinants of pregnancy-related outcomes, and it may provide effective strategies for the prevention of pregnancy complications in Korean pregnant women.

Abstract
OBJECTIVE To investigate the effect of parity and interpregnancy interval (IPI) on perinatal outcomes in advanced maternal age (AMA) parturients. METHODS A population-based retrospective cohort study of all women older than 40 years, who had a singleton live birth after 24 weeks in the United States in 2017 Women were categorized to three groups by parity and interval from last delivery: primiparas, multiparas with IPI ≤ 5 years, and multiparas with IPI > 5 years. Primary outcome was composite adverse neonatal outcome (preterm delivery <34 weeks, birthweight <2000 g, neonatal seizure, neonatal intensive care unit admission, Apgar score <7 at 5 min, or assisted ventilation >6 h). Secondary outcome was composite adverse maternal outcome and other adverse perinatal outcomes. Univariate and multivariate analysis were used to compare between groups. RESULTS During 2017, 3,864,754 deliveries were recorded into the database. Following exclusion, 109,564 AMA gravidas entered analysis. Of them, 24,769 (22.6%) were nulliparas, 39,933 (36.4%) were multiparas with IPI ≤ 5 years, and 44,862 (40.9%) were multiparas with IPI > 5 years. Composite neonatal outcome was higher in nulliparas and in multiparas with IPI > 5 years, in comparison to multiparas with IPI ≤ 5 years (16% vs. 13% vs. 10%, respectively, p < 0.05). Maternal composite outcome was similar between groups. In the multivariable analysis, relative to nulliparas, only multiparity with IPI ≤ 5 years had a protective effect against the composite neonatal outcome (aOR 0.97, 95% CI 0.95-0.99, p < 0.001). CONCLUSION Among AMA gravidas, multiparity with IPI ≤ 5 years has a significant protective effect against adverse neonatal outcomes when compared to nulliparas. Multiparity with IPI > 5 years is no longer protective.

Abstract
Background: Our aim was to evaluate trends of childbearing during medical training, evaluate issues of infertility, and measure institutionalized barriers to childbearing among women physicians. Materials and Methods: Attendees of a national women physician's leadership conference (Brave Enough Women Physicians Continuing Medical Education Conference) were surveyed during the conference using Qualtrics© (2019 Qualtrics, Provo, UT), in September 2019. Survey data included demographics, training level, and medical specialty. Data related to reproductive health factors, pregnancy status and history, current number of children, medical history related to pregnancy, breastfeeding history, institutional family planning support, and use of previous fertility treatments were collected. Descriptive analyses were done using IBM SPSS v26.0. Results: Three hundred seventy-seven survey participants were included in the study. 10.6% of respondents reported at least one pregnancy during medical school, versus 78.8% as a practicing physician. Of the participants, 25.8% reported having taken off 1 month or less of clinical duties after giving birth, 39.4% reported that their job prevented breastfeeding for the desired length of time, and 52.2% reported significant workplace limitations to breastfeeding. Of them, 25.5% reported having had fertility issues in the past. Fertility drugs (72.9%) was the most common fertility treatment method used, followed by fertility tracking (54.2%). Demands of training (72.9%) and long work hours (61.5%) were the most cited factors in delaying having children as reported by women physicians. Conclusions: This study reported several barriers related to fertility, family planning, and reproductive health among women physicians. Our results highlight the need for a paradigm shift in fertility awareness and institutional support for childbearing during medical training, postgraduate training programs, and in practice for women in medicine.

Abstract
Background: The late occurrence of adiposity peak (AP) and the early occurrence of adiposity rebound (AR) are considered the earliest indicators for obesity and its related health conditions later in life. However, there is still limited information for their upstream factors. Therefore, in this study, we aimed to identify the parental and child factors associated with the timing of AP and AR in the early stage of life. Methods: This is a population-based longitudinal study conducted in Shanghai, China. The BMI data of children born between September 2010 and October 2013 were followed from birth to 80 months. Subject-specific body mass index trajectories were fitted by non-linear mixed-effect models with natural cubic spline functions, and the individual's age at AP and AR was estimated. The generalized linear regression models were applied to identify the upstream factors of late occurrence of AP and early occurrence AR. Results: For 7,292 children with estimated AP, boys were less likely to have a late AP [adjusted risk ratio (RR) = 0.83, 95% confidence interval (CI): 0.77-0.90, p < 0.001], but preterm born children had a higher risk of a late AP (adjusted RR = 1.25, 95% CI: 1.07-1.47, p < 0.01). For 10,985 children with estimated AR, children with breastfeeding longer than 4 months were less likely to have an early AR (adjusted RR = 0.80, 95% CI: 0.73-0.87, p < 0.001), but children who were born to advanced-age mothers and who were born small for gestational age had a higher risk of having an early AR (adjusted RR = 1.21, 95% CI: 1.07-1.36, p < 0.01; adjusted RR = 1.20, 95% CI: 1.04-1.39, p = 0.01). Conclusions: Modifiable pre-birth or early-life factors associated with the timing of AP or AR were found. Our findings may help develop prevention and intervention strategies at the earliest stage of life to control later obesity and the health conditions and diseases linked to it.

Abstract
CONTEXT.— The percentage of pregnant women with advanced maternal age (AMA) has increased during the past several decades due to various socioeconomic factors and advances in assisted reproduction. These pregnancies are associated with adverse maternal and fetal outcomes. However, the underlying placental pathology has not been well described. OBJECTIVE.— To investigate the placental histopathology associated with AMA pregnancies. DESIGN.— Placental pathology from 168 AMA women 35 years or older at delivery was reviewed. The cases were subdivided into 2 age subgroups, ages 35 to 39 and 40 or older, as well as a "pure AMA" subgroup where the only indication for placental examination was AMA. A group of 60 consecutive non-AMA placentas was also identified and used as comparison. The spectrum of histologic features in each case was catalogued. RESULTS.— Of the overall AMA cases, meconium deposition was seen in 55% (93 of 168), chorangiosis in 40% (68 of 168), and acute chorioamnionitis in 36% (60 of 168). Fetal vascular malperfusion was also seen with high frequency (30%; 50 of 168). Two histologic alterations found to be significantly different between the 35 to 39 and greater than 40 age subgroups were fetal vascular malperfusion (11% [7 of 65] versus 42% [43 of 103]; P = .001) and delayed villous maturation (1.5% [1 of 65] versus 13% [13 of 103]; P = .02). The pure AMA subgroup showed no statistically significant differences compared with the overall AMA group. Chronic deciduitis was the only statistically significant difference between the overall AMA group and the non-AMA comparison group (14% [23 of 168] versus 30% [18 of 60]; P = .02). CONCLUSIONS.— Our findings, particularly the high frequency of fetal vascular malperfusion, suggest that AMA should be an independent indication for placental pathologic examination.

Eur J Obstet Gynecol Reprod Biol 2020; 253:213-219. [PMID: 32889327 DOI: 10.1016/j.ejogrb.2020.08.022] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Revised: 08/17/2020] [Accepted: 08/21/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND Women of advanced maternal age, defined as ≥ 35 years at delivery, are at increased risk of multiple complications during pregnancy, with perinatal death being one of the most feared. For instance, the risk of stillbirth at term in this subgroup of women is higher than in younger women, and particularly high beyond 39 weeks of gestation. Induction of labor at 39-40 weeks might help prevent some cases of perinatal death, however, the fact that induction of labor has been historically associated with an increased risk of cesarean delivery and the knowledge that advanced maternal age is an independent risk factor for cesarean delivery are some of the major reasons why clinicians are reluctant to offer elective induction of labor in this particular group. OBJECTIVE The aim of the study was to assess if induction of labor in advanced maternal age was associated with increased rates of cesarean delivery when compared to expectant management. MATERIAL AND METHODS We performed an electronic search limited to published articles available between January 2000 and March 2020. Randomized clinical trials and retrospective studies with large cohorts comparing induction of labor with expectant management in singleton pregnancies at term, of women aged ≥ 35 years were included. The primary outcome was the rate of cesarean delivery in induction of labor versus expectant management, and secondary outcomes were the occurrence of assisted vaginal delivery and postpartum hemorrhage. RESULTS Eight studies, including 81151 pregnancies (26,631 in the induction group and 54,520 expectantly managed), were included in the analysis. Six of the included studies were randomized clinical trials with the remaining two being observational and retrospective cohort studies. Induction of labor was not associated with a significant increased risk of cesarean delivery (OR 0.97, 95 % CI 0.86-1.1), assisted vaginal delivery (OR 1.12, 95 % CI 0.96-1.32) or postpartum hemorrhage (OR 1.11, 95 % CI 0.88-1.41). DISCUSSION The belief that induction of labor is associated with an increased risk of cesarean delivery is based on the results of retrospective studies comparing induction with spontaneous labor at the same gestational age. However, at any point in a pregnancy, the comparison should be between induction of labor and expectant management, with the latter contributing to a pregnancy of greater gestation age and not always leading to spontaneous labor. When comparing induction to expectant management, our study shows no significant increase of cesarean section, assisted vaginal delivery or postpartum hemorrhage. Our study was not powered to assess neonatal outcomes, and additional research is needed to confirm whether induction of labor might have a positive effect in preventing stillbirth. CONCLUSION Induction of labor at term in advanced maternal age has no significant impact on cesarean delivery rates, assisted vaginal delivery or postpartum hemorrhage, giving additional reassurance to obstetricians who would consider this intervention in this particular subgroup.

Abstract
BACKGROUND Advanced biological aging, as measured by epigenetic aging indices, is associated with early mortality and morbidity. Associations between maternal epigenetic aging indices in pregnancy and pregnancy outcomes, namely gestational length and birthweight, have not been assessed. The purpose of this study was to examine whether epigenetic age during pregnancy was associated with gestational length and birthweight. RESULTS The sample consisted of 77 women from the Los Angeles, CA, area enrolled in the Healthy Babies Before Birth study. Whole blood samples for DNA methylation assay were obtained during the second trimester (15.6 ± 2.15 weeks gestation). Epigenetic age indices GrimAge acceleration (GrimAgeAccel), DNAm PAI-1, DNAm ADM, and DNAm cystatin C were calculated. Gestational length and birthweight were obtained from medical chart review. Covariates were maternal sociodemographic variables, gestational age at blood sample collection, and pre-pregnancy body mass index. In separate covariate-adjusted linear regression models, higher early second trimester GrimAgeAccel, b(SE) = - .171 (.056), p = .004; DNAm PAI-1, b(SE) = - 1.95 × 10-4 (8.5 × 10-5), p = .004; DNAm ADM, b(SE) = - .033 (.011), p = .003; and DNAm cystatin C, b(SE) = 2.10 × 10-5 (8.0 × 10-5), p = .012, were each associated with shorter gestational length. Higher GrimAgeAccel, b(SE) = - 75.2 (19.7), p < .001; DNAm PAI-1, b(SE) = - .079(.031), p = .013; DNAm ADM, b(SE) = - 13.8 (3.87), p = .001; and DNAm cystatin C, b(SE) = - .010 (.003), p = .001, were also associated with lower birthweight, independent of gestational length. DISCUSSION Higher maternal prenatal GrimAgeAccel, DNAm PAI-1, DNAm ADM, and DNAm cystatin C were associated with shorter gestational length and lower birthweight. These findings suggest that biological age, as measured by these epigenetic indices, could indicate risk for adverse pregnancy outcomes.

Abstract
In 2017, 23% of all live births in the United Kingdom were to women aged over 35 years. Decisions around the timing of delivery for such women must balance the risks of prolongation of the pregnancy and of iatrogenic harm from timed delivery. Women of advanced maternal age have a small age-related elevated risk of term stillbirth. Antenatal monitoring and the route of delivery should not differ from those for younger women. The induction of labour at 39 weeks for such women does not appear to increase the risk of emergency caesarean section or to have any short-term adverse effects on mother or baby. There have been no studies on the long-term effects of induction in this group. Nevertheless, it seems reasonable to offer women of advanced maternal age, induction of labour at 39 weeks where resources are available to safely provide this.

High Frequency of Intravenous Injection of Human Adipose Stem Cell Conditioned Medium Improved Embryo Development of Mice in Advanced Maternal Age through Antioxidant Effects. Animals (Basel) 2020; 10:ani10060978.

Abstract
Simple Summary In this study, we examined the anti-oxidative effect of human adipose stem cell conditioned medium (ASC-CM) on the ovary and uterus of mice in advanced maternal age (AMA) and the optimal conditions of intravenous injection for ASC-CM administration. Human ASC-CM upregulated expression of antioxidant genes, restored the quality of oocytes derived from aged ovaries and resulted in improved in vitro and in vivo embryo development. The anti-oxidative effect human ASC-CM was optimized with high frequency of administration. Comprehensively, our study successfully introduced the potential of ASC-CM as an antioxidant intervention against age-related infertility in AMA. Abstract Advanced maternal age (AMA) has become prevalent globally. With aging, weakened antioxidant defense causes loss of normal function in the ovary and uterus due to oxidative stress. Here, we aimed to improve embryo development in AMA mice by intravenous injection (IV) of human adipose stem cell conditioned medium (ASC-CM) at various frequencies and intervals as an antioxidant intervention. Four- and six-month-old female ICR (Institute of Cancer Research) mice were randomly divided into groups IV treated with human ASC-CM under different conditions, and in vitro and in vivo embryo development were evaluated. Consequently, compared to the control group, blastocyst formation rate of parthenotes was significantly promoted in 4-month-old mice and the mean number of implanted fetuses after natural mating was significantly increased by approximately two-fold in 6-month-old mice. Through gene analysis, the anti-apoptotic and anti-oxidative effects of human ASC-CMs were confirmed in the ovaries and uterus of pregnant mice at both ages. In particular, ovarian expression of gpx1 and catalase drastically increased in 6-month-old mice. Furthermore, the levels of gpx1 and catalase were further increased, with a high frequency of injection regardless of age. Thus, we demonstrated for the first time the anti-oxidative effect of human ASC-CM administration against ovarian aging and the optimal injection condition.

Abstract
Women who conceive at 35 years of age or older, commonly known as advanced maternal age, have a higher risk of facing parturition complications and their children have an increased risk of developing diseases later in life. However, the immunological mechanisms underlying these pathological processes have yet to be established. To fill this gap in knowledge, using a murine model and immunophenotyping, we determined the effect of advanced maternal age on the main cellular branch of adaptive immunity, T cells, at the maternal-fetal interface and in the offspring. We report that advanced maternal age impaired the process of labor at term, inducing dystocia and delaying the timing of delivery. Advanced maternal age diminished the number of specific proinflammatory T-cell subsets [T helper type 1 (Th1): CD4+ IFN-γ+ , CD8+ IFN-γ+ and Th9: CD4+ IL-9+ ], as well as CD4+ regulatory T cells (CD4+ CD25+ FoxP3+ T cells), at the maternal-fetal interface prior to term labor. Advanced maternal age also altered fetal growth and survival of the offspring in early life. In addition, infants born to advanced-age mothers had alterations in the T-cell repertoire but not in CD71+ erythroid cells (CD3- CD71+ TER119+ cells). This study provides insight into the immune alterations observed at the maternal-fetal interface of advanced-age mothers and their offspring.

Abstract
In this cross-sectional study, we evaluated data from the 2014 Bangladesh Demographic and Health Survey (BDHS), which consisted of 7,707 married women aged 15-49 years who lived with at least one child younger than 5 years. This study's primary aim was to examine the relationship between maternal high-risk fertility behavior and child morbidity. To define high-risk fertility behaviors, we considered three variables: maternal age at the time of delivery, birth order, and birth interval. The main outcome measures were mortality-related disease in the past 2 weeks (acute respiratory infection [ARI], diarrhea, and fever) and low birth weight (LBW). We used modified Poisson regression with generalized estimating equations to assess the relationships between the variables of interest. Results indicate that a substantial portion of women (34%) exhibited high-risk fertility patterns; 28.7% engaged in a single high-risk behavior and 5.4% engaged in multiple high-risk behaviors. After adjusting for relevant covariates, high-risk fertility behaviors were significantly associated with an increased likelihood of ARI (adjusted relative risk [ARR]: 1.22, 95% CI: 1.05-1.50), diarrhea (ARR: 1.18, 95% CI: 1.03-1.35), fever (ARR: 1.29, 95% CI: 1.11-1.58), and LBW (ARR: 1.27, 95% CI: 1.10-1.52). In addition, engaging in multiple high-risk fertility behaviors appeared to have far-reaching consequences on the outcomes measured. Maternal high-risk fertility behaviors are important predictors of morbidity in children younger than 5 years. Preventing high-risk fertility behavior may reduce childhood morbidity and mortality in Bangladesh.

Abstract
Background: The prevalence of chronic disease in pregnant women has consistently risen over the past two decades. Substantial evidence demonstrates that maternal chronic disease is associated with adverse medical outcomes like preterm birth, but less research has characterized postpartum outcomes such as infant feeding practices. It is recommended that infants be exclusively breastfed from birth to 6 months given the numerous health benefits it provides.Objective: To determine the association between maternal chronic disease and breastfeeding outcomes.Methods: We analyzed cross-sectional self-report data from the 2015/2016 Canadian Community Health Survey, restricted to women who gave birth within 2 years of data collection (n = 2100, rounded). The exposure was professionally diagnosed chronic physical disease (e.g. diabetes, arthritis, heart disease). The outcomes were breastfeeding non-initiation and early cessation of breastfeeding before 6 months. Multivariable logistic regression modeling was used to estimate adjusted odds ratios (AOR) with 95% confidence intervals (CIs). Estimates were bootstrapped and weighted to represent the national population.Results: Overall, 11.9% (95% CI 9.8-14.1) of women reported chronic disease, and were more likely to be single, be Canadian born, have low education, and be overweight/obese than women without chronic disease. The mean maternal age was approximately 30 years in both groups. Women with chronic disease had similar odds of breastfeeding non-initiation (AOR 0.96, 95% CI 0.54-1.71) and early cessation of any breastfeeding (AOR 1.40, 95% CI 0.82-2.40), but over twice the odds of early cessation of exclusive breastfeeding (AOR 2.48, 95% CI 1.49-4.12) compared to unaffected women.Conclusion: Mothers with chronic disease initiate and continue some form of breastfeeding to six months as often as their unaffected peers. However, they have substantially higher odds of ceasing exclusive breastfeeding before the recommended 6 months. Findings suggest a need to investigate the reasons for this disparity to ensure that appropriate breastfeeding support is available for women with chronic disease and their children.

Abstract
To study the effect of very advanced maternal age on perinatal outcomes. A retrospective cohort study of women aged 45 years and above, who delivered ≥22 weeks of gestation in a single tertiary center between 1/ 2011 and 12/ 2018. Maternal and neonatal outcomes were compared between women ≥50 years and women of 45-49 years at delivery. Of 83,661 parturients, 593 (0.7%) were 45-49 years old and 64 (0.07%) were ≥50 years old. Obstetrical characteristics were comparable, though the rate of chronic hypertension and preeclampsia with severe features were greater in women ≥50 years (6.2% vs 1.4%, p = 0.04, 15.6% vs 7.0%, p = 0.01, 95% CI 0.19-0.86, respectively). Elective cesarean deliveries were independently associated with advanced maternal age ≥50 (OR 2.63 95% CI 1.21-5.69). Neonatal outcomes were comparable for singletons, but rates of ventilatory support and composite severe neonatal outcomes were higher in twin pregnancies of women ≥50 years (42.8% vs 13.5%, p = 0.01, and 21.4% vs 4.0%, p = 0.03, respectively). Healthy women ≥50 have higher elective cesarean rates, despite similar maternal and neonatal characteristics.

Pregnancy complications and risk of preterm birth according to maternal age: A population-based study of delivery hospitalizations in Alberta. Acta Obstet Gynecol Scand 2019; 99:459-468. [PMID: 31713841 DOI: 10.1111/aogs.13769] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2019] [Revised: 11/04/2019] [Accepted: 11/06/2019] [Indexed: 01/10/2023]
Abstract
INTRODUCTION Pregnancy-related medical complications are associated with a 2- to 5-fold increased risk of preterm birth (PTB), but the nature of this etiologic relation in context with maternal factors remains poorly understood. Previous studies have generally treated maternal age as a confounder but overlooked its potential as an effect modifier, whereby the magnitude of the effect of complications on PTB could differ significantly across age groups. We investigated whether advanced maternal age (≥35 years) modified the association between pregnancy complications and PTB, and compared population-attributable fractions of PTB from complications in women older vs younger than 35 years. MATERIAL AND METHODS We analyzed population-based, cross-sectional data from the Alberta Discharge Abstract Database for women aged 18-50 years with singleton live births in hospital between 2014 and 2017 (n = 152 246). Complications were preeclampsia, gestational diabetes, and placental disorders identified using diagnostic codes. Outcomes were spontaneous (sPTB) or iatrogenic (iPTB) PTB before 37 weeks of gestation. We estimated risk ratios and risk differences using modified Poisson and log binomial regression, respectively, adjusting for confounders (pregnancy history, comorbidities). Population-attributable fractions estimates were calculated from risk ratios. Age modification was tested using interaction terms and Z-tests. RESULTS Prevalence of advanced maternal age was 19.2%. Pregnancy complications and s/iPTB were more common among women aged ≥35 years. Age modified the risk of PTB from preeclampsia only, with risk differences of 9.9% (95% CI 7.2%-12.6%) in older women vs 6.1% (95% CI 4.8%-7.4%) in younger women (P-interaction = 0.012) for sPTB, and 29.5% (95% CI 26.0%-33.1%) vs 20.8% (95% CI 18.9%-22.6%, P-interaction <0.001) for iPTB. Population-attributable fractions of s/iPTB types for all complications were consistently 2%-5% larger in women aged ≥35 years, and significantly larger for preeclampsia (sPTB: 5.1% vs 2.7%, P = 0.002; iPTB: 18.8% vs 14.0%, P < 0.001) and placental disorders (sPTB: 12.5% vs 8.7%, P < 0.001; iPTB: 13.2% vs 8.9%, P < 0.001). CONCLUSIONS Of the pregnancy complications studied, advanced maternal age only modified the association between PTB and preeclampsia, such that older women with preeclampsia have a higher risk for s/iPTB than younger counterparts. Pregnancy complications contribute to a sizable proportion of PTBs in Alberta, especially among women aged ≥35 years. Findings may inform clinical risk assessment and population-level policy targeting PTB.

Abstract
OBJECTIVE To estimate absolute risks of obstetric outcomes in the USA according to maternal age at first birth from age 15 to 45 separately by maternal race. DESIGN AND SETTING Population-based cohort study. SETTING Vital statistics Birth Cohort-Linked Birth- Infant Death Data Files and Fetal Death Data Files in the USA. PARTICIPANTS 16 514 849 births to nulliparous women from 2004 to 2013. OUTCOME MEASURES We estimated absolute risks of obstetric outcomes (multiple gestations, caesarean delivery, early and late preterm birth, small for gestational age birth, stillbirth, neonatal mortality, postneonatal infant mortality) at each year of maternal age from 15 to 45 years using logistic regression in the overall population and stratified by maternal race. We modelled maternal age flexibly to allow curvilinear shapes and plotted risk curves for each outcome. RESULTS In the overall population, multiple gestations, caesarean delivery and stillbirth risks were lowest at young maternal ages with linear or quadratic increases with age. Curves for preterm birth, small for gestational age, neonatal mortality and postneonatal mortality were u or j shaped, with nadirs between 20 and 29 years, and elevated risks at both younger and older maternal ages. In race-stratified analyses, the shapes of the curves were generally similar across races. Risks increased for all women for all outcomes after age 30. However, increased risks at young maternal ages were most pronounced for white and Asian/Pacific Islander women, for whom young childbearing was least common. Conversely, risks at older ages were more pronounced for Black and American Indian/Alaska Native women, for whom delayed childbearing was least common. CONCLUSION Our findings confirm risks associated with first births to women younger than 20 and older than 30 years, provide easily interpretable risk curves and illuminate variability in these relationships across categories of maternal race in the USA.

Abstract
The early neonatal period accounts for approximately half of the deaths of young children under one year of age, and the neonatal near miss can recognize factors causing this high number of deaths. Thus, the aim of this study is to determine whether advanced maternal age increases the chance of neonatal near miss, in addition is to identify which factors are associated with the neonatal near miss, stratified by parity. Data are from the 2011-2012 Birth in Brazil study, which used a national population-based sample of 15,092 newborns of women between 20-29 and 35 years of age or more (advanced maternal age). Multiple logistic regression was performed to test the association between neonatal near miss and prenatal and childbirth variables, pre-gestational diseases, obstetric history and socioeconomic characteristics, stratified by parity. Advanced maternal age was to be statistically associated with neonatal near miss in nulliparous (OR = 1.62; 95%CI: 1.05-2.50) and multiparous (OR = 1.51; 95%CI: 1.20-1.91) when compared to women 20-29 years of age. For nulliparous women, the main variables statistically associated with neonatal near miss were multiple gestation (OR = 8.91) and hypertensive disease (OR = 2.57), whereas forceps-assisted vaginal delivery (OR = 7.19) and multiple gestation (OR = 4.47) were the variables associated for multiparous women. Neonatal near miss has been shown to be connected with access to health services for childbirth, gestational complications and maternal characteristics, mainly advanced maternal age. Therefore, to properly monitor and classify maternal gestational risk, to control gestational complications during prenatal care, and to correctly refer these women to childbirth care should be priority strategies for healthcare services.

Abstract
Background and objective Over recent decades, a progressive increase in the maternal age at childbirth has been observed in developed countries, posing a health risk for both women and infants. The aim of this study was to analyze the association between advanced maternal age (AMA) and maternal and neonatal morbidity. Material and methods A cross-sectional study of 3,315 births was conducted in the north of Spain in 2014. We compared childbirth between women aged 35 years or older, with a reference group of women aged between 24 and 27 years. AMA was categorized based on ordinal ranking into 35–38 years, 39–42 years, and >42 years to estimate a dose-response pattern (the older the age, the greater the risk). As an association measure, crude and adjusted Odds Ratios (OR) were estimated by non-conditional logistic regression and 95% Confidence Intervals (95%CI) were calculated. Results Repeated abortions were more common among women of AMA in comparison to pregnant women aged 24–27 years (reference group): adjusted OR = 2.68; 95%CI (1.52–4.73). A higher prevalence of gestational diabetes was also observed among women of AMA, reaching statistical significance when restricted to first time mothers: adjusted OR = 8.55; 95%CI (1.12–65.43). In addition, the possibility of an instrumental delivery was multiplied by 1.6 and the possibility of a cesarean by 1.5 among women of AMA, with these results reaching statistical significance, and observing a dose-response pattern. Lastly, there were associations between preeclampsia, preterm birth (<37 weeks) and low birthweight, however without reaching statistical significance. Conclusion Our results support the association between AMA and suffering repeated abortions. Likewise, being of AMA was associated with a greater risk of suffering from gestational diabetes, especially among primiparous women, as well as being associated with both instrumental deliveries and cesareans among both primiparous and multiparous women.

Abstract
PURPOSE To identify whether older primiparas have more complications than do women who continue to deliver children into their late reproductive age. Patients of at least 35 years of age at delivery were included. Within this cohort, data from primiparous and multiparous women were compared. METHODS This retrospective study was based on electronic medical records from a single academic center, with more than 7000 deliveries annually. The impact of parity on maternal complications was assessed using a multivariate logistic regression model that adjusted for baseline maternal characteristics and medical history. RESULTS During the study period, there were 54 283 deliveries in our medical center. A total of 13,982 (25.7%) patients were at least 35 years old at delivery. The rate of twin pregnancy was higher in the primiparous group (1.9%) as compared to the multiparous group (0.8%, 95% CI 0.30-0.64, P < 0.001), as was the incidence of delivery prior to 34 weeks (6.1% of the primiparas versus 2.9% of the multiparas, P < 0.001, OR 2.16, 95% CI 1.75-2.68); hypertensive disorders (3.9% versus 1.7%, P < 0.001, 95% CI 0.33-0.57); diabetes (4.6% versus 3.2%, P = 0.003, 95% CI 0.55-0.88); and IUGR (10.5% versus 4.7%, P < 0.001, 95% CI 0.35-049), respectively. The increased risk for pre-term delivery, hypertensive disorders, diabetes, and IUGR was maintained after logistic regression analysis. CONCLUSION We found that pregnancy complications typical to older parous women are significantly more common among primiparas, indicating that not only older age, but also having a first child relatively late in the reproductive period contributes to adverse pregnancy outcomes.

Abstract
RESEARCH QUESTION To study gestational hypertensive disorders in oocyte donation pregnancies compared with other modes of conception at very advanced maternal age. DESIGN A historical cohort study of all women aged 45-47 years who gave birth to singletons at a tertiary medical centre between March 2011 and May 2018, at 24 weeks' gestation or later. Pregnancy outcomes were compared between donor oocyte (IVF-OD), IVF using autologous oocytes (IVF-A) and naturally conceived pregnancies. A multivariate logistic regression was used to evaluate the association between the mode of conception and gestational hypertensive disorders. RESULTS The final analysis included 159, 68 and 73 patients in the IVF-OD, IVF-A and natural conception groups, respectively. The rate of gestational hypertensive disorders was significantly higher among those who conceived by IVF compared with those who conceived naturally but did not differ between the two IVF groups (27.0% for IVF-OD, 19.1% for IVF-A, P = 0.204; 5.5% for natural conception, P < 0.001 and P = 0.013 compared with IVF-OD and IVF-A, respectively). The results remained similar in a multivariate logistic regression analysis. The rate of Caesarean deliveries was significantly higher in the IVF-OD and IVF-A groups compared with the natural conception group (83.6%, 70.6% and 37.0%, respectively, P < 0.001), but other pregnancy outcomes did not differ between the groups. CONCLUSIONS IVF pregnancies in the late fifth decade of life were associated with significantly higher rates of gestational hypertensive disorders compared with naturally conceived pregnancies. No difference existed between the two IVF groups. These results may highlight the impact of IVF itself on gestational hypertensive disorders at very advanced maternal age.

Abstract
OBJECTIVE To clarify how race is associated with adverse maternal outcomes and risk for women aged 40 years or older. METHODS This retrospective cohort study used the Nationwide Inpatient Sample for the years 1998-2014. Women aged 40-54 years were included. Race and ethnicity were categorized as non-Hispanic white, non-Hispanic black, Hispanic, Asian or Pacific Islander, Native American, other, and unknown. Temporal trends in severe maternal morbidity and overall comorbid risk by race in women aged 40 years or older were evaluated as were common pregnancy complications including preeclampsia, gestational diabetes, and cesarean delivery. Adjusted models were created to assess factors associated with severe morbidity. RESULTS A total of 1,724,694 deliveries were included in this analysis. Severe maternal morbidity increased over the study period from 1.6% in 1998-2000 to 3.0% from 2013 to 2014. Black women had the highest rates of severe morbidity at both the beginning (2.4% in 1998-2000) and the end (4.9% in 2013-2014) of the study period. During this same period, comorbid risk based on medical conditions and other factors increased overall and individually by race. Black women also experienced the absolute largest increase from 1998-2003 to 2010-2014 in risk for acute renal failure, disseminated intravascular coagulation, transfusion, and hysterectomy. Pregnancy complications including preeclampsia, cesarean delivery, and gestational diabetes were more common at the end compared with the beginning of the study for black, white, and Hispanic women. The adjusted risk ratio for overall severe morbidity for black compared with white race was 1.81 (95% CI 1.76-1.87). Black women had a substantially higher risk of death than white women (risk ratio 4.71, 95% CI 3.36-6.61), and Hispanic women had more than twice the risk of death (risk ratio 2.13, 95% CI 1.48-3.07) as white women. CONCLUSION Although black women older than 40 years were at increased risk for adverse outcomes and severe morbidity, this differential was of smaller magnitude than reported mortality risk.

Abstract
IMPORTANCE Over the past 2 decades, there has been a trend toward increasing maternal age in many high-income countries. Maternal age may lead to greater attendant morbidity and mortality for Canadian mothers. OBJECTIVE To investigate the association of maternal age, adjusting for patient-level and hospital-level factors, with severe maternal morbidity (SMM) and maternal death in Canada. DESIGN, SETTING, AND PARTICIPANTS A nationwide population-based cohort study of all antepartum, peripartum, and postpartum women and adolescents seen at Canadian acute care hospitals from April 1, 2004, to March 31, 2015. All analyses were completed on September 13, 2018. EXPOSURES Maternal age at the index delivery. MAIN OUTCOMES AND MEASURES Severe maternal morbidity and maternal death during pregnancy and within 6 weeks after termination of pregnancy. RESULTS During the study period, there were 3 162 303 new pregnancies (mean [SD] maternal age, 29.5 [5.6] years) and 3 533 259 related hospital admissions. There were 54 219 episodes of SMM (17.7 cases per 1000 deliveries) in the entire study period, with a 9.8% relative increase from 2004-2005 to 2014-2015, in addition to an increasing proportion of pregnancies to older mothers. Independent patient-level factors associated with SMM included increasing Maternal Comorbidity Index; maternal age 19 years or younger and 30 years or older, with the greatest risk experienced by women 45 years or older (odds ratio [OR], 2.69; 95% CI, 2.34-3.06 compared with maternal age 20-24 years); and lowest income quintile (OR, 1.19; 95% CI, 1.14-1.22 compared with highest income quintile). Hospital-level factors associated with SMM included specific provinces. Independent patient-level factors associated with maternal mortality included increasing Maternal Comorbidity Index, age 40 to 44 years (OR, 3.39; 95% CI, 1.68-6.82 compared with age 20-24 years), age 45 years or older (OR, 4.39; 95% CI, 1.01-19.10 compared with age 20-24 years), and lowest income quintile (OR, 4.14; 95% CI, 2.03-8.50 compared with highest income quintile). Hospital-level factors associated with maternal mortality included lowest hospital pregnancy volume. CONCLUSIONS AND RELEVANCE In Canada, maternal age and SMM have increased over the past decade. Results of this study suggest that province of residence, maternal comorbidity, residence income quintile, and extremes of maternal age, especially those 45 years or older, were associated with SMM and mortality. These findings are relevant to prospective parents, their health care team, and public health planning.
