Abstract Background Pregnancy among adolescent girls in Bangladesh is high, with 66% of women under the age of 18 reporting a first birth; this issue is particularly acute in the northern region of Bangladesh, an area that is especially impoverished and where girls are at heightened risk. Using formative research, CARE USA examined the underlying social, individual and structural factors influencing married girls’ early first birth and participation in alternative opportunities (such as education or economic pursuits) in Bangladesh. Methods In July of 2017, researchers conducted in-depth interviews of community members in two sub-districts of northern Bangladesh (Kurigram Sadar and Rajarhat). Participants (n = 127) included adolescent girls (both married and unmarredi), husbands of adolescent girls, influential adults in the girls’ lives, community leaders, and health providers. All interviews were transcribed, coded and organized using Dedoose software. Results Participants recognize the health benefits of delaying first birth, but stigma around infertility and contraceptive use, pressure from mothers-in-law and health provider bias interfere with a girl’s ability to delay childbearing. Girls’ social isolation, lack of mobility or autonomy, and inability to envision alternatives to early motherhood compound the issue; provider bias may also prevent access to methods. While participants agree that pursuit of education and economic opportunities are important, better futures for girls do not necessarily supersede their marital obligations of childrearing and domestic chores. Conclusions Findings indicate the need for a multi-level approach to delaying early birth and stimulating girls’ participation in economic and educational pursuits. Interventions must mitigate barriers to reproductive health care; train adolescent girls on viable economic activities; and provide educational opportunities for girls. Effective programs should also address contextual issues by including immediate members of the girls’ families, particularly the husband and mother-in-law.

Early marriage (EM) and early childbearing (ECB) have far‐reaching consequences. This study describes the prevalence, trends, inequalities, and drivers of EM and ECB in South Asia using eight rounds of Demographic and Health Survey data across 13 years. We report the percentage of ever‐married women aged 20–24 years (n = 105,150) married before 18 years (EM) and with a live birth before 20 years (ECB). Relative trends were examined using average annual rate of reduction (AARR). Inequalities were examined by geography, marital household wealth, residence, and education. Sociodemographic drivers of changes for EM were assessed using regression decomposition analyses. We find that EM/ECB are still common in Bangladesh (69%/69%), Nepal (52%/51%), India (41%/39%), and Pakistan (37%/38%), with large subnational variation in most countries. EM has declined fastest in India (AARR of –3.8%/year), Pakistan (–2.8%/year), and Bangladesh (–1.5%/year), but EM elimination by 2030 will not occur at these rates. Equity analyses show that poor, uneducated women in rural areas are disproportionately burdened. Regression decomposition analysis shows that improvements in wealth and education explained 44% (India) to 96% (Nepal) of the actual EM reduction. Investments across multiple sectors are required to understand and address EM and ECB, which are pervasive social determinants of maternal and child wellbeing. [ABSTRACT FROM AUTHOR]

A sub-Antarctic fur seal, Arctocephalus tropicalis, pup was located on Inaccessible Island in the Tristan da Cunha archipelago (TdC), well before the start of the annual breeding (pupping and mating) season in 2018. It was born a few days before 27 September 2018, at least 59 days before the next pup was observed on the island in 2018 and 75 days before the median birthdate for the species at the TdC. A malfunctioning of the obligate delay of implantation of the blastocyst in its mother was likely the cause of the early birth. [ABSTRACT FROM AUTHOR]

Background: Although infant and child mortality rates have decreased substantially worldwide over the past two decades, efforts continue in many nations to further these declines. The identification of pertinent perinatal factors that are associated with early childhood mortality would help with these efforts. We investigated the association of two crucial perinatal factors, gestational age and severe neonatal morbidity at birth, with mortality during infancy (29-364 days) and early childhood (1-5 years).Methods: The study population included all singleton livebirths, ≥32 weeks' gestation in New South Wales, Australia in 2001-11. Birth data were linked to hospitalisation morbidity data and deaths data (linked birth cohort n = 871 916), and multivariable Cox regression models were used to assess mortality.Results: The median follow-up time per child was 4.95 years (range 0.00-5.92 years; 3 614 738 total person-years), with 984 deaths observed. Gestational age was associated with increased mortality, and specifically from deaths attributable to infections, respiratory conditions, and injuries during infancy, but not during early childhood. Severe neonatal morbidity strongly mediated the effects of gestational age during infancy, but not during early childhood, and was associated with increased mortality from circulatory, nervous, and respiratory system causes.Conclusions: The direct effects of gestational age on mortality extended up to 1 year of age, whereas severe neonatal morbidity remained associated with heightened mortality into early childhood. Efforts to maximise the health and well-being of vulnerable infants, with emphasis on preventing infections and injuries, may help further reduce early childhood mortality.

Child marriage has large negative effects on the girls who marry early and their children, as well as communities and societies as a whole. Ending child marriage is a target under the Sustainable Development Goals, but investments to delay the age at first marriage remain limited in countries where child marriage is widespread. As part of a broader argument to make the economic case for ending child marriage, this paper provides a simple approach for measuring the share of early childbirths likely due to child marriage in developing countries. This estimation matters because many of the negative impacts of child marriage on development outcomes for the girls who marry early and their children are through early childbirths – having a child before the age of 18 (for a mother), or being born of a mother younger than 18 (for a child). The estimates provided in this paper suggest that most early childbirths in developing countries are likely due to child marriage.

Anderson, Cheryl and Mccarley, Michelle
- Abstract
Purpose: To explore and compare associations among demographics, childbirth-related Stressors, depressive symptoms, gestational age, and psychological birth trauma (PBT) among adolescents. Study Design and Methods: This cross-sectional, descriptive, comparative study compared two groups of adolescents for PBT. From a larger study dataset, we identified all adolescents delivering prior to 38 weeks (n = 30) and randomly selected 30 adolescents delivering between 38 and 42 weeks gestation for comparison. PBT was defined via birth appraisal, assessed by a one-item rating scale, and trauma impact, assessed via the Impact of Event Scale. Surveys, including the Center for Epidemiological Studies-Depression Scale, were completed within 72 hours of birth. We used frequencies and percentages to describe the sample and Chi square, Spearman Rank-Order Correlation, and Pearson's Product Moment Correlation to determine relationships between variables. Chi square and ANOVA statistical tests determined group differences. Results: Adolescents were primarily Latina, single, primigravidas, and over 16 years of age. Adolescents delivering before 38 weeks experiencing cesarean births reported symptoms of depression and were highest risk for PBT. Additionally adolescents delivering before 38 weeks reported lack of pain control and unsupportive caregivers in labor. Clinical Implications: Healthcare professionals cognizant of the potential risk factors for PBT can help vulnerable adolescents through caregiver support, adequate pain control in labor, education, and screening and treatment of depressive symptoms. Follow-up postdischarge, especially for high-risk adolescents, should be arranged to monitor for continued, delayed, or remitting symptoms of depression and PBT. [ABSTRACT FROM AUTHOR]

This review is an attempt to provide an integrative view for the biological changes triggered by fetal stress through a multidisciplinary approach. Acceleration of brain and lung maturation in certain risk pregnancies was first described clinically and confirmed by biochemical, electrophysiological and experimental data. Moreover, new experimental findings suggest that a fetal clock centrally mediated by fetal nutritional status could determine timing of parturition. However, some skepticism persisted about the usefulness of this body of knowledge for obstetrical management in developed countries. The interest concerning this adaptation to intrauterine stress was later renewed from various sources, as developed in Part II. [Copyright &y& Elsevier]

Aim: Although many pregnancies and birth processes have passed without any problems, all pregnancies have various risks. The main purpose should be to control risky situations in pregnancy without threatening the health of mother and baby. Our study was carried out in order to investigate the complications related to the risks determined by the risk assessments of women who were followed during pregnancy and puerperants in a family health center.Methods: Women who were registered in the family medicine unit and whose pregnancy and puerperium were followed were scanned through the automation system during the study period. During the pregnancy periods, risk factors and time of birth were examined. Patients with any risk factor were considered as risky pregnant and examined whether a pathological condition developed during pregnancy or during the postpartum period.Results: It was determined that during pregnancy period 10 pregnant women had at least one risk factor of 81 pregnant women whose risk assessments were examined. The distribution of risk factors was as follow; 3 with grand-multiparity story, 3 with preterm delivery, 2 with pregnancy over 35, 2 with Rh incompatibility, 1 with cardiovascular disease, 1 with multiple pregnancy, 1 with preterm labor, and under 18 years of age in 1 pregnant women was determined. It was found statistically significant that the risk of having a risk factor was higher than that of non-risk patients at 38 weeks (p, Amaç: Birçok gebelik ve doğum süreci sorunsuz yaşansa da gebelikler çeşitli riskler barındırır. Gebelikteki riskli durumları, anne ve bebeğin sağlığını tehdit etmeden kontrol altına almak asıl amaç olmalıdır. Çalışmamız bir aile sağlığı merkezinde, gebelik ve lohusalık boyunca takip edilmiş kadınların risk değerlendirmeleri ile tespit edilen risklerine bağlı komplikasyon gelişme durumlarını incelemek amacıyla yapılmıştır.Yöntem: Aile hekimliği birimimizde kayıtlı kadınlardan çalışma döneminde gebelik ve lohusalık izlemleri yapılmış olanlar otomasyon sistemi üzerinden tarandı. Gebelik dönemlerindeki risk varlığı, doğum haftaları incelendi. Herhangi bir risk faktörüne sahip olan gebeler riskli gebe olarak kabul edilip, gebelikte veya lohusalık döneminde patolojik bir durum gelişip gelişmediği incelenmiştir.Bulgular: Gebelik ve lohusalık takipleri yapılmış 81 kadının risk değerlendirme formları incelendiğinde 10 tanesinin gebelik döneminde en az bir risk faktörü olduğu tespit edildi. Saptanan risk faktörlerinin dağılımı ise şu şekildeydi; akraba evliliği yapmış 3, grandmultiparite öyküsü olan 3, erken doğum öyküsü olan 2, 35 yaş üstü gebelik durumunda olan 2, Rh uygunsuzluğu olan 2, kardiyovasküler hastalığı olan 1, çoğul gebeliği olan 1, erken doğum eylemi olan 1 ve 18 yaş altında olan 1 gebede saptandı. Risk faktörü mevcut olan gebelerin, risk olmayanlara göre 38 haftadan erken doğum yapma riskinin daha fazla olduğu istatistiksel olarak anlamlı tespit edildi (p

- Abstract
Background. Preterm birth (PTB) is a devastating syndrome impacting 1 in 7.5 births to African American women. Improved methods to predict and prevent PTB are sorely needed and require a mechanistic understanding of PTB not yet achieved. Gestation may be shortened through premature initiation of an inflammatory cascade. Impaired interleukin(IL)-1beta regulation may play a role among African American women and can be considered according to IL-1beta and IL-1 receptor antagonist(Ra) production, cortisol levels, and glucocorticoid sensitivity. Chapter 2 reviews how a bio-panel of these mediators may predict early birth.Several single nucleotide polymorphisms (SNPs) have been linked to lower IL-1Ra and psychosocial stress/depressive symptoms to enhanced IL-1beta; production, cortisol elevations, and decreased glucocorticoid sensitivity. Therefore, Chapters 3 and 4 address the following aims: evaluate if 1) allele status predicts shortened gestation and whether relationships are mediated by: a) IL-1Ra production, and/or b) modification of IL-1beta and IL-1Ra production relationship, and 2) psychosocial stress/depressive symptoms predict shortened gestation and whether relationships are related to: a) IL-1beta production, b) cortisol levels, and/or c) glucocorticoid sensitivity. Methods. This prospective cohort study enrolled 96 African American women at 28-32 weeks gestation. Stress and depressive symptom inventories were administered. Blood was drawn. Allelic discrimination was performed. IL-1beta and IL-1Ra production were measured following ex vivo stimulation. Plasma cortisol levels and the neutrophil:lymphocyte ratio were measured (loss of expected positive association suggests decreased glucocorticoid sensitivity). Medical records were reviewed. Associations were examined. Results. Women lacking minor allele A at IL1RN SNP rs2637988 had 3.09 times higher odds of delivery before 39 weeks, 95%CI=1.07-8.92. The relationship between IL-1Ra production and timing of delivery depended upon allele status. One ng/ml greater IL-1Ra production was associated with 29% lower odds of delivery before 38 weeks among women possessing minor allele A, 95%CI=.41-1.2, but 2.78 times greater odds among women lacking minor allele A, 95%CI=1.06-7.27. The SNP moderated the association between IL-1beta; and IL-1Ra production, beta=-1.23, t=-3.00, p=.004. Though, influential data points were identified. Higher IL-1beta production predicted delivery before 38 weeks, OR=1.45, 95%CI=1.10-1.91. Women with significant depressive symptoms delivered 5.59 days earlier than women without significant depressive symptoms, beta=-.26, t=-2.35, p=.021. One microgram/dl greater cortisol was associated with delivery .61 days earlier, beta=-.25, t=-2.26, p=.026. The relationship between cortisol and the neutrophil:lymphocyte ratio did not differ by depressive symptom status. However, one microgram/dl greater cortisol was associated with 1.41 times greater odds of delivery before 39 weeks among women with, 95%CI=1.01-1.96, but not without significant depressive symptoms, OR=.98, 95%CI=.83-1.14. A one unit positive difference in the neutrophil:lymphocyte ratio trended toward greater odds of delivery before 39 weeks among women with, OR=2.28, 95%CI=.95-5.57, but not without significant depressive symptoms, OR=.72, 95%CI=.45-1.16. Conclusions. Results support an inflammatory etiology to early birth among African Americans. The IL1RN SNP may relate to timing of delivery by modifying the IL-1beta:IL-1Ra relationship. Results also suggest that elevated cortisol may play a role in early delivery. Decreased glucocorticoid sensitivity may be important among women without depressive symptoms. Continued work in this area is warranted.

- Abstract
Congenital birth defects and early/premature birth are common complex conditions affecting populations throughout the world, the interaction of which accounts for a significant proportion of neonatal morbidity and mortality. The relationship between these two conditions is not well understood. Several congenital birth defects can directly lead to early delivery. In addition, certain fetal conditions may necessitate early or premature delivery, several of which are also associated with maternal conditions necessitating early birth. Further understanding of both the incidences and causes of congenital birth defects and of early and premature birth will facilitate establishment of strategies to improve neonatal mortality and morbidity., (Copyright © 2013 Elsevier Inc.
