Poverty during pregnancy: Its effects on child health outcomes

The association between poverty and longitudinal patterns of adverse childhood experiences across childhood and adolescence: Findings from a prospective population-based cohort study in the UK

BACKGROUND

Adverse childhood experiences (ACEs) affect up to half the general population, they are known to co-occur, and are particularly common among those experiencing poverty. Yet, there are limited studies examining specific patterns of ACE co-occurrence considering their developmental timing.

OBJECTIVE

To examine the longitudinal co-occurrence patterns of ACEs across childhood and adolescence, and to examine the role of poverty in predicting these.

PARTICIPANTS AND SETTING

The sample was 8859 children from the Avon Longitudinal Study of Parents and Children, a longitudinal prospective population-based UK birth cohort.

METHODS

Repeated measures of ten ACEs were available, occurring in early childhood (birth-5 years), mid-childhood (6-10 years), and adolescence (11-16 years). Latent class analysis was used to identify groups of children with similar developmental patterns of ACEs. Multinomial regression was used to examine the association between poverty during pregnancy and ACE classes.

RESULTS

Sixteen percent of parents experienced poverty. A five-class latent model was selected: "Low ACEs" (72·0 %), "Early and mid-childhood household disharmony" (10·6 %), "Persistent parental mental health problems" (9·7 %), "Early childhood abuse and parental mental health problems" (5·0 %), and "Mid-childhood and adolescence ACEs" (2·6 %). Poverty was associated with a higher likelihood of being in each of the ACE classes compared to the low ACEs reference class. The largest effect size was seen for the "Early and mid-childhood household disharmony" class (OR 4·70, 95 % CI 3·68-6·00).

CONCLUSIONS

A multifactorial approach to preventing ACEs is needed - including support for parents facing financial and material hardship, at-risk families, and timely interventions for those experiencing ACEs.

Family poverty, neighbourhood greenspace and perinatal outcomes

OBJECTIVE

The relationship between low income and adverse perinatal outcomes, such as low birth weight and developmental delays, is well established making the search for protective factors important. One such factor may be neighbourhood greenspace. This study elucidates the role of urban neighbourhood greenspace in the relationship between income and perinatal outcomes in a nationally representative birth cohort from the UK.

METHODS

Data on 14 050 infants participating in the initial wave at age 9 months of the Millennium Cohort Study were used (51% male, 20% non-white, 52% living in disadvantaged areas). We tested whether the association between income and perinatal outcomes is moderated by urban greenspace (measured in deciles) before and after adjustments for confounding. The perinatal outcomes included birth weight, gestational age (in days), communication and motor delays. The models were adjusted for the infant's sex and ethnicity, mother's age, education, substance use and mental health as well as area disadvantage and air pollution.

RESULTS

Neighbourhood greenspace moderated the association between income and gestational age, even after adjustment for all confounders, b=-0.11, 95% CI (-0.215, -0.004). For births in low-income households, in particular, it was associated with an increase in gestational age by an average of approximately 3 days. However, after adjustment, greenspace was not found to influence birth weight, communication or motor delays at age 9 months.

CONCLUSION

The biophilic design of urban environments is a modifiable factor for improving perinatal outcomes in the UK as urban greenspaces appear to be mitigating the risk of preterm birth associated with family poverty.

Community level factors and racial inequities in delivery hospitalizations involving severe maternal morbidity in the United States, 2016-2019

The objective of this study was to evaluate the racial and ethnic disparities in delivery hospitalizations involving severe maternal morbidity (SMM) by location of residence and community income. We used the 2016 to 2019 Healthcare Cost and Utilization Project National Inpatient Sample. International Classification of Diseases, Tenth Revision, Clinical Modification codes were used to identify delivery hospitalizations with SMM. Using logistic regression models, we examined the association between race and ethnicity and delivery hospitalizations involving SMM. In adjusted analyses, the models were stratified by location of residence and community income and adjusted for patient and hospital characteristics. In rural areas, non-Hispanic Black women (AOR 1.50; 95% CI 1.25-1.79) and women of other races (AOR 1.32; 95% CI 1.03-1.69) had an increased odds of experiencing a delivery hospitalization involving SMM when compared to non-Hispanic White women. In micropolitan areas, non-Hispanic Black women (AOR 1.88; 95% CI 1.79-1.97), non-Hispanic Asian/Pacific Islander women (AOR 1.54; 95% CI 1.16-2.05), and women of other races (AOR 1.31; 95% CI 1.03-1.67) had an increased odds of experiencing a delivery hospitalization involving SMM when compared to non-Hispanic White women. Non-Hispanic Black women also had increased odds of experiencing a delivery hospitalization involving SMM in communities with the lowest income (quartile 1) (AOR 1.59; 95% CI 1.49-1.66), middle income (quartiles 2 and 3) (AOR 1.81; 95% CI 1.72-1.91), and highest income (AOR 2.09; 95% CI 1.90-2.29) when compared to non-Hispanic White women. We found that location of residence and community income are associated with racial and ethnic differences in SMM in the United States. These factors, outside of individual factors assessed in previous studies, provide a better understanding of some of the structural and systemic factors that may contribute to SMM.

Social fund and infant mortality: Evidence from an anti-poverty policy in Northeast Brazil

This paper evaluates the effects of a social fund that meets the needs of the poor in Northeast Brazil, the Fundos Estaduais de Combate e Erradicação da Pobreza (FECEP). The program could have improved infant health by reducing poverty and improving access to health care, sanitation, food, and housing. Using a difference-in-differences approach robust to heterogeneous treatment effects, we confirm that the program has effectively reduced poverty in treated areas. Furthermore, we document that this poverty reduction is associated with a significant decline in infant mortality. These findings provide consistent evidence that targeted public investments can improve living conditions in vulnerable regions.

Identifying Longer-Term Health Events and Outcomes and Health Service Use of Low Birthweight CALD Infants in Australia

INTRODUCTION

Approximately one-third of all births in Australia each year are by culturally and linguistically diverse (CALD) women. CALD women are at an increased risk of adverse pregnancy and birth outcomes including prematurity and low birthweight. Infants born weighing less than 2500 g are susceptible to increased risk of ill health and morbidities such as cognitive defects including cerebral palsy, and neuro-motor functioning.

METHODS

An existing linked administrative dataset, Maternity 1000 was utilized for this study which has identified all children born in Queensland (QLD), Australia, between 1st July 2012 to 30th June 2018 from the QLD Perinatal Data Collection. This has then been linked to the QLD Hospital Admitted Patient Data Collection, QLD Hospital Non-Admitted Patient Data Collection, QLD Emergency Department Data Collection, and Medicare Benefits Schedule and Pharmaceutical Benefits Scheme Claims Records between 1 and 2012 to 30th June 2019.

RESULTS

Culturally and linguistically diverse infants born with low birthweight had higher mean and standard deviation of all health events and outcomes; potentially preventable hospitalisations, hospital re-admissions, ED presentations without admissions, and development of chronic diseases compared to non-CALD infants born with low birthweight.

DISCUSSION

Results from this study highlight the disparities in health service use and health events and outcomes associated with low birthweight infants, between both CALD and Australian born women. This study has responded to the knowledge gap of low birthweight on the Australian economy by identifying that there are significant inequalities in access to health services for CALD women in Australia, as well as increased health events and poor birth outcomes for these infants when compared to those of mothers born in Australia.

Could commercial meal kits be part of the solution to food insecurity during pregnancy? An Australian exploratory study

AIM

To explore the nutritional content of meal kits from two main Australian companies over a 6-week period against healthy eating guidelines for pregnancy.

METHOD

Across the 6-week period, weekly meal kits from both Provider 1 and Provider 2 were purchased, 36 individual meals were assessed. All data were analysed for the development of a macronutrient and micronutrient profile of meals. Extracted data were macronutrient, vitamin, and mineral composition, which were compared against the healthy eating guidelines for pregnant women in Australia and New Zealand.

RESULTS

Meal kits include higher levels of sodium, and lower levels of dietary fibre, calcium, magnesium, zinc, iron, thiamin, riboflavin, grains, and dairy when compared against the guidelines for healthy eating for pregnant women in Australia and New Zealand.

CONCLUSIONS AND IMPLICATIONS

Meal kits may increase meals prepared and consumed in the home, and thanks to the clear instructions and pre-portioned ingredients, may reduce stress related to food preparation. They have the potential to provide nutritionally adequate meals to pregnant women as a way to mitigate food insecurity or hunger during pregnancy and may provide some nutritional benefits and have the potential to remove some of the challenges with maintaining an adequate diet when pregnant.

Birth, cognitive and behavioral effects of intrauterine cannabis exposure in infants and children: A systematic review and meta-analysis

BACKGROUND AND AIMS

Δ9-tetrahydrocannabinol (THC), the principal psychoactive component of cannabis, has been implicated in affecting fetal neurodevelopment by readily crossing the placenta. However, little is known regarding the long-term effects of intrauterine cannabis exposure. This systematic review and meta-analysis synthesized prospective and cross-sectional human studies to measure the effects of intrauterine cannabis exposure on birth, behavioral, psychological and cognitive outcomes in infancy until early childhood.

METHODS

Reporting according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement, cross-sectional and prospective studies published from database inception until June 2023, investigating developmental outcomes of infants, toddlers and young children with intrauterine cannabis exposure were considered. All articles were obtained from PubMed or PsycINFO databases.

RESULTS

The literature search resulted in 932 studies, in which 57 articles met eligibility criteria. The meta-analysis revealed that intrauterine cannabis exposure increases the risk of preterm delivery [odds ratio (OR) = 1.68, 95% confidence interval (CI) = 1.05-2.71, P = 0.03], low birth weight (OR = 2.60, CI = 1.71-3.94, P < 0.001) and requirement for neonatal intensive care unit (NICU) admission (OR = 2.51, CI = 1.46-4.31; P < 0.001). Our qualitative synthesis suggests that intrauterine cannabis exposure may be associated with poorer attention and externalizing problems in infancy and early childhood. We found no evidence for impairments in other cognitive domains or internalizing behaviors.

CONCLUSIONS

Prenatal cannabis use appears to be associated with lower birth weight, preterm birth and neonatal intensive care unit admission in newborns, but there is little evidence that prenatal cannabis exposure adversely impacts behavioral or cognitive outcomes in early childhood, with the exception of attention and externalizing problems.

A cost-effectiveness analysis of a South African pregnancy support grant

Poverty among expectant mothers often results in sub-optimal maternal nutrition and inadequate antenatal care, with negative consequences on child health outcomes. South Africa has a child support grant that is available from birth to those in need. This study aims to determine whether a pregnancy support grant, administered through the extension of the child support grant, would be cost-effective compared to the existing child support grant alone. A cost-utility analysis was performed using a decision-tree model to predict the incremental costs (ZAR) and disability-adjusted life years (DALYs) averted by the pregnancy support grant over a 2-year time horizon. An ingredients-based approach to costing was completed from a governmental perspective. The primary outcome was the incremental cost-effectiveness ratio (ICER). Deterministic and probabilistic sensitivity analyses were performed. The intervention resulted in a cost saving of R13.8 billion ($930 million, 95% CI: ZAR3.91 billion - ZAR23.2 billion/ $1.57 billion - $264 million) and averted 59,000 DALYs (95% CI: -6,400-110,000), indicating that the intervention is highly cost-effective. The primary cost driver was low birthweight requiring neonatal intensive care, with a disaggregated incremental cost of R31,800 ($2,149) per pregnancy. Mortality contributed most significantly to the DALYs accrued in the comparator (0.68 DALYs). The intervention remained the dominant strategy in the sensitivity analyses. The pregnancy support grant is a highly cost-effective solution for supporting expecting mothers and ensuring healthy pregnancies. With its positive impact on child health outcomes, there is a clear imperative for government to implement this grant. By investing in this program, cost savings could be leveraged. The implementation of this grant should be given high priority in public health and social policies.

Respectful Maternal Care Experience in Low- and Middle-Income Countries: A Systematic Review

Background and Objectives: Respectful maternity care promotes practices that acknowledge women's preferences and women and newborns' needs. It is an individual-centered strategy founded on ethical and human rights principles. The objective of this systematic review is to identify the impact of income on maternal care and respectful maternity care in low- and middle-income countries. Materials and Methods: Data were searched from Google Scholar, PubMed, Web of Science, NCBI, CINAHL, National Library of Medicine, ResearchGate, MEDLINE, EMBASE database, Scopus, Cochrane Central Register of Controlled Trials (CENTRAL), and Maternity and Infant Care database. This review followed PRISMA guidelines. The initial search for publications comparing low- and middle-income countries with respectful maternity care yielded 6000 papers, from which 700 were selected. The review articles were further analyzed to ensure they were pertinent to the comparative impact of income on maternal care. A total of 24 articles were included, with preference given to those published from 2010 to 2023 during the last fourteen years. Results: Considering this study's findings, respectful maternity care is a crucial component of high-quality care and human rights. It can be estimated that there is a direct association between income and maternity care in LMICs, and maternity care is substandard compared to high-income countries. Moreover, it is determined that the evidence for medical tools that can enhance respectful maternity care is sparse. Conclusions: This review highlights the significance of improving maternal care experiences, emphasizing the importance of promoting respectful practices and addressing disparities in low- and middle-income countries.

Lower academic performance among children with perinatal HIV exposure in Botswana

INTRODUCTION

Studies have reported a higher risk of suboptimal neurodevelopment among children who are HIV-exposed uninfected (HEU) compared to children HIV-unexposed uninfected (HUU). Actual academic performance among school-aged children by HIV exposure status has not been studied.

METHODS

Academic performance in Mathematics, Science, English, Setswana and overall among children enrolled in the Botswana-based FLOURISH study who were attending public primary school and ranging in age from 7.1 to 14.6 years were compared by HIV exposure status using a Cochran-Mantel-Haenszel test. Lower academic performance was defined as a grade of "C" or lower (≤60%). Unadjusted and adjusted logistic regression models were fit to assess for an association between HIV exposure and lower academic performance.

RESULTS

Between April 2021 and December 2022, 398 children attending public primary school enrolled in the FLOURSH study, 307 (77%) were HEU. Median age was 9.4 years (IQR 8.9-10.2). Only 17.9% of children HEU were breastfeed versus 100% of children HUU. Among children HEU, 80.3% had foetal exposure to three-drug antiretroviral treatment, 18.7% to zidovudine only and 1.0% had no antiretroviral exposure. Caregivers of children HEU were older compared to caregivers of children HUU (median 42 vs. 36 years) and more likely to have no or primary education only (15.0% vs. 1.1%). In unadjusted analyses, children HEU were more likely to have lower overall academic performance compared to their children HUU (odds ratio [OR]: 1.96 [95% confidence interval (CI): 1.16, 3.30]), and lower performance in Mathematics, Science and English. The association was attenuated after adjustment for maternal education, caregiver income, breastfeeding, low birth weight and child sex (aOR: 1.86 [95% CI: 0.78, 4.43]).

CONCLUSIONS

In this Botswana-based cohort, primary school academic performance was lower among children HEU compared to children HUU. Biological and socio-demographic factors, including child sex, appear to contribute to this difference. Further research is needed to identify modifiable contributors, develop screening tools to identify the risk of poor academic performance and design interventions to mitigate risk.

Communal Poverty Is a Significant Risk Factor for Neonatal Seizures

INTRODUCTION

Neonatal seizures (NS) are a severe condition with significant mortality and long-term morbidity. This study aims to identify risk factors for NS in a racially or ethnically diverse population in Israel.

METHODS

This is a case-control study. The cases were all newborns born between 2001 and 2019 at Emek Medical Center in Israel and admitted with NS. Two healthy controls born in the same period were matched for each case. Demographic, maternal, and neonatal variables were abstracted from the electronic medical files.

RESULTS

A total of 139 cases were matched with 278 controls. Residing in a town with lower socioeconomic status (SES), primiparity and abnormal prenatal ultrasound were significantly associated with NS. Prematurity, assisted delivery, a lower birthweight, being small for gestational age, and lower Apgar score were also associated with NS. In two different multivariable regression models, lower SES (odds ratio [OR] = 4.07) and Arab race/ethnicity (OR = 2.66) were risk factors for NS. Other significant risk factors in the multivariable regression models included an assisted mode of delivery (OR = 2.33), prematurity (OR = 2.27), and a 5-minute Apgar score below 7 (OR = 54.1).

DISCUSSION

Communal poverty, as reflected by lower SES of towns of residence, was found to be a stronger risk factor than race or ethnicity, for NS. More studies should focus on social class, as a risk factor for maternal and neonatal adverse outcomes. As SES is a modifiable variable every effort should be invested in fighting communal poverty and improving the SES of impoverished towns and population.

Mechanisms of equality and inequality in mammalian societies

The extent of (in)equality is highly diverse across species of social mammals, but we have a poor understanding of the factors that produce or inhibit equitable social organizations. Here, we adopt a comparative evolutionary perspective to test whether the evolution of social dominance hierarchies, a measure of social inequality in animals, exhibits phylogenetic conservatism and whether interspecific variation in these traits can be explained by sex, age or captivity. We find that hierarchy steepness and directional consistency evolve rapidly without any apparent constraint from evolutionary history. Given this extraordinary variability, we next consider multiple factors that have evolved to mitigate social inequality. Social networks, coalitionary support and knowledge transfer advantage to privilege some individuals over others. Nutritional access and prenatal stressors can impact the development of offspring, generating health disparities with intergenerational consequences. Intergenerational transfer of material resources (e.g. stone tools, food stashes, territories) advantage those who receive. Nonetheless, many of the same social species that experience unequal access to food (survival) and mates (reproduction) engage in levelling mechanisms such as food sharing, adoption, revolutionary coalitions, forgiveness and inequity aversion. Taken together, mammals rely upon a suite of mechanisms of (in)equality to balance the costs and benefits of group living. This article is part of the theme issue 'Evolutionary ecology of inequality'.

Advocacy in neonatology: current issues and introduction to the series

Advocacy is an increasingly important skill for neonatologists. As social factors play a greater influence on short & long-term newborn outcomes, neonatal physicians must be attentive to policy factors and work to ensure they benefit the health of both patients and the specialty. In this article, we review advocacy issues of current relevance to neonatal practice, including the "Born Alive Executive Order," the "Newborn Screening Saves Lives Act," subspecialty loan repayment and legislation related to donor human milk, as well as introduce topics further discussed as part of the American Academy of Pediatrics Section on Neonatal-Perinatal Medicine Advocacy Series.

Harmful effects of opioid use in pregnancy: A scientific review commissioned by the European Board and College of obstetrics and gynaecology (EBCOG)

Caring for pregnant women who have a recreational opioid use disorder is a common clinical challenge in modern obstetric care. These are an elusive population who often have multiple social issues that complicate their pregnancy management. Comprehensive and supportive maternal care can motivate these mothers to change her lifestyle. Multidisciplinary non-judgemental approach with appropriate medication and management, can result in good pregnancy outcomes for mother and her baby.

Perinatal Health Outcomes Across Rural and Nonrural Counties Within a Single Health System Catchment

Background

Perinatal health outcomes are influenced by a variety of socioeconomic, behavioral, and economic factors that reduce access to health services. Despite these observations, rural communities continue to face barriers, including a lack of resources and the fragmentation of health services.

Objective

To evaluate patterns in health outcomes, health behaviors, socioeconomic vulnerability, and sociodemographic characteristics across rural and nonrural counties within a single health system catchment area.

Methods

Socioeconomic vulnerability metrics, health care access as determined by licensed provider metrics, and behavioral data were obtained from FlHealthCHARTS.gov and the County Health Rankings. County-level birth and health data were obtained from the Florida Department of Health. The University of Florida Health Perinatal Catchment Area (UFHPCA) was defined as all Florida counties where ≥5% of all infants were delivered at Shands Hospital between June 2011 and April 2017.

Results

The UFHPCA included 3 nonrural and 10 rural counties that represented more than 64,000 deliveries. Nearly 1 in 3 infants resided in a rural county, and 7 out of 13 counties did not have a licensed obstetrician gynecologist. Maternal smoking rates (range 6.8%-24.8%) were above the statewide rate (6.2%). Except for Alachua County, breastfeeding initiation rates (range 54.9%-81.4%) and access to household computing devices (range 72.8%-86.4%) were below the statewide rate (82.9% and 87.9%, respectively). Finally, we found that childhood poverty rates (range 16.3%-36.9%) were above the statewide rate (18.5%). Furthermore, risk ratios suggested negative health outcomes for residents of counties within the UFHPCA for each measure, except for infant mortality and maternal deaths, which lacked sample sizes to adequately test.

Conclusions

The health burden of the UFHPCA is characterized by rural counties with increased maternal death, neonatal death, and preterm birth, as well as adverse health behaviors that included increased smoking during pregnancy and lower levels of breastfeeding relative to nonrural counties. Understanding perinatal health outcomes across a single health system has potential to not only estimate community needs but also facilitate planning of health care initiatives and interventions in rural and low-resource communities.

Ameliorating poverty-related communication and swallowing disabilities: Sustainable Development Goal 1

PURPOSE

More than 700 million people globally are still living in extreme poverty. No poverty (Sustainable Development Goal 1, SDG 1), is considered to be the greatest global challenge. This paper aims to outline the effects of poverty on communication and swallowing disabilities across the lifespan and steps to take for its amelioration.

RESULT

Poverty and disability are in a vicious cycle with each being a cause for and a consequence of the other. Poverty has incontrovertible and significant ramifications for communication and swallowing disabilities across the lifetime from pregnancy to old age. The individual, family and social burden and costs of these disabilities have lifelong economic and social consequences.

CONCLUSION

Considering poverty is a known and important determinant of communication and swallowing disabilities, the most potent weapon is to focus on preventing and ameliorating poverty-related communication and swallowing disabilities in children. A call to action is issued to speech-language pathologists to take steps towards this goal. This commentary paper focusses on Sustainable Development Goal of no poverty (SDG 1) and also addresses zero hunger (SDG 2), reduced inequalities (SDG 10), and climate action (SDG 13).

Tourism-induced poverty impacts of COVID-19 in Indonesia

International tourism is an important sector in developing countries for its ability to alleviate poverty. Impacts of COVID-19 are detrimental to all tourism destinations. This paper examines the pandemic effects on poverty of regional economies based on a multi-household CGE model using Indonesia as a case study. Results are critically important for policymakers, as the pandemic retracts achievement of poverty reduction significantly, more than a decade of effort for Bali in this case study. Adverse impacts are transferred to other non-tourism destinations through inter-regional trade flows. The paper provides empirical evidence to call for government's targeted support to combat the economic impacts of the pandemic improve poverty more effectively.

Low income and schizophrenia risk: a narrative review

Despite decades of research, the precise etiology of schizophrenia is not fully understood. Ample evidence indicates that the disorder derives from a complex interplay of genetic and environmental factors during vulnerable stages of brain maturation. Among the plethora of risk factors investigated, stress, pre- and perinatal insults, and cannabis use have been repeatedly highlighted as crucial environmental risk factors for schizophrenia. Compelling findings from population-based longitudinal studies suggest low income as an additional risk factor for future schizophrenia diagnosis, but underlying mechanisms remain unclear. In this narrative review, we 1) summarize the literature in support of a relationship between low (parental) income and schizophrenia risk, and 2) explore the mediating role of chronic stress, pre- and perinatal factors, and cannabis use as established risk factors for schizophrenia. Our review describes how low income facilitates the occurrence and severity of these established risk factors and thus contributes to schizophrenia liability. The broadest influence of low income was identified for stress, as low income was found to be associated with exposure to a multitude of severe psychological and physiological stressors. This narrative review adds to the growing literature reporting a close relationship between income and mental health.

Prenatal environmental stressors impair postnatal microglia function and adult behavior in males

Gestational exposure to environmental toxins and socioeconomic stressors is epidemiologically linked to neurodevelopmental disorders with strong male bias, such as autism. We model these prenatal risk factors in mice by co-exposing pregnant dams to an environmental pollutant and limited-resource stress, which robustly activates the maternal immune system. Only male offspring display long-lasting behavioral abnormalities and alterations in the activity of brain networks encoding social interactions. Cellularly, prenatal stressors diminish microglial function within the anterior cingulate cortex, a central node of the social coding network, in males during early postnatal development. Precise inhibition of microglial phagocytosis within the anterior cingulate cortex (ACC) of wild-type (WT) mice during the same critical period mimics the impact of prenatal stressors on a male-specific behavior, indicating that environmental stressors alter neural circuit formation in males via impairing microglia function during development.

Block et al. show that combined exposure to air pollution and maternal stress during pregnancy activates the maternal immune system and induces male-specific impairments in social behavior and circuit connectivity in offspring. Cellularly, prenatal stressors diminish microglia phagocytic function, and inhibition of microglia phagocytosis phenocopies behavioral deficits from prenatal stressors.

Association of Prenatal Exposure to Early-Life Adversity With Neonatal Brain Volumes at Birth

Importance

Exposure to early-life adversity alters the structural development of key brain regions underlying neurodevelopmental impairments. The association between prenatal exposure to adversity and brain structure at birth remains poorly understood.

Objective

To examine whether prenatal exposure to maternal social disadvantage and psychosocial stress is associated with neonatal global and regional brain volumes and cortical folding.

Design, Setting, and Participants

This prospective, longitudinal cohort study included 399 mother-infant dyads of sociodemographically diverse mothers recruited in the first or early second trimester of pregnancy and their infants, who underwent brain magnetic resonance imaging in the first weeks of life. Mothers were recruited from local obstetric clinics in St Louis, Missouri from September 1, 2017, to February 28, 2020.

Exposures

Maternal social disadvantage and psychosocial stress in pregnancy.

Main Outcomes and Measures

Confirmatory factor analyses were used to create latent constructs of maternal social disadvantage (income-to-needs ratio, Area Deprivation Index, Healthy Eating Index, educational level, and insurance status) and psychosocial stress (Perceived Stress Scale, Edinburgh Postnatal Depression Scale, Everyday Discrimination Scale, and Stress and Adversity Inventory). Neonatal cortical and subcortical gray matter, white matter, cerebellum, hippocampus, and amygdala volumes were generated using semiautomated, age-specific, segmentation pipelines.

Results

A total of 280 mothers (mean [SD] age, 29.1 [5.3] years; 170 [60.7%] Black or African American, 100 [35.7%] White, and 10 [3.6%] other race or ethnicity) and their healthy, term-born infants (149 [53.2%] male; mean [SD] infant gestational age, 38.6 [1.0] weeks) were included in the analysis. After covariate adjustment and multiple comparisons correction, greater social disadvantage was associated with reduced cortical gray matter (unstandardized β = -2.0; 95% CI, -3.5 to -0.5; P = .01), subcortical gray matter (unstandardized β = -0.4; 95% CI, -0.7 to -0.2; P = .003), and white matter (unstandardized β = -5.5; 95% CI, -7.8 to -3.3; P < .001) volumes and cortical folding (unstandardized β = -0.03; 95% CI, -0.04 to -0.01; P < .001). Psychosocial stress showed no association with brain metrics. Although social disadvantage accounted for an additional 2.3% of the variance of the left hippocampus (unstandardized β = -0.03; 95% CI, -0.05 to -0.01), 2.3% of the right hippocampus (unstandardized β = -0.03; 95% CI, -0.05 to -0.01), 3.1% of the left amygdala (unstandardized β = -0.02; 95% CI, -0.03 to -0.01), and 2.9% of the right amygdala (unstandardized β = -0.02; 95% CI, -0.03 to -0.01), no regional effects were found after accounting for total brain volume.

Conclusions and Relevance

In this baseline assessment of an ongoing cohort study, prenatal social disadvantage was associated with global reductions in brain volumes and cortical folding at birth. No regional specificity for the hippocampus or amygdala was detected. Results highlight that associations between poverty and brain development begin in utero and are evident early in life. These findings emphasize that preventive interventions that support fetal brain development should address parental socioeconomic hardships.

Severe maternal hardships are associated with food insecurity among low-income/lower-income women during pregnancy: results from the 2012–2014 California maternal infant health assessment

Background

Assess the associations between ten severe maternal hardships and food insecurity experienced during pregnancy.

Methods

Data on 14,274 low-income/lower-income women (below 400% of the income to federal poverty guideline ratio) from the statewide-representative 2010–2012 California Maternal and Infant Health Assessment were used to estimate food security status prevalence. Prevalence of severe maternal hardships by food security status was estimated. Multinomial logistic regression was used to assess the associations between severe maternal hardship and food security status, adjusting for sociodemographic characteristics.

Results

Food insecurity was common among low- and lower-income pregnant women in California; 23.4% food insecure and an additional 11.5% marginally secure. In adjusted analysis, nine of ten hardships were associated with food security status. Only the respondent or someone close to the respondent having a problem with alcohol or drugs was not associated with food security status after adjusting for socioeconomic factors. Husband/partner losing a job, depressive symptoms, not having practical support and intimate partner violence were consistently associated with marginal, low and very low food security status. Each additional severe maternal hardship a woman experienced during pregnancy was associated with a 36% greater risk of reporting marginal food security (Relative Risk Ratio 1.36, 95% CI: 1.27, 1.47), 54% for low food security (Relative Risk Ratio 1.54, 95% CI: 1.44, 1.64), and 99% for very low food security (Relative Risk Ratio 1.99, 95% CI: 1.83, 2.15).

Conclusions

Food security status was strongly linked with several maternal hardships that could jeopardize maternal and/or infant health.

Services—including prenatal care and nutritional assistance—for a large proportion of pregnant women should address a wide range of serious unmet social needs including food insecurity.

Postpartum scarcity-adversity disrupts maternal behavior and induces a hypodopaminergic state in the rat dam and adult female offspring

Postpartum adversity is among the strongest predictors for the emergence of postpartum depression (PPD) in humans and a translational risk factor employed in rodent models. Parental care is disturbed under conditions of environmental adversity, including low resource environments, and in PPD. Nonetheless, the neural changes associated with these adversity-induced maladaptive behavioral states remain poorly understood. Postpartum scarcity-adversity can be modeled in rats by providing the dam with limited bedding and nesting (LBN) materials, which mimics the effects of a stressful low resource environment in potentiating maltreatment/neglect in humans. Indeed, LBN exposure from postpartum days (PD) 2-9 increased adverse maternal behaviors, impaired pup retrieval, and increased passive stress coping responses. Since mesolimbic dopamine (DA) activity is an important mechanism for motivated maternal behavior and is implicated in PPD, we assessed the impact of postpartum scarcity-adversity on in vivo electrophysiological properties of ventral tegmental area (VTA) DA neurons at two timepoints. We found reduced numbers of active VTA DA neurons in LBN dams at PD 9-10 but not PD-21, suggesting a transient impact on VTA population activity in LBN dams. Finally, we assessed the impact of early life scarcity-adversity on VTA DA function by conducting VTA recordings in adult female offspring and found a long-lasting attenuation in DA activity. These findings highlight a link between adversity-induced deficits in DA function and disrupted maternal behavior, suggesting the VTA/mesolimbic DA system as a potential mechanism by which postpartum scarcity-adversity drives aberrant maternal behavior, and early postnatal programming of adult VTA function in the offspring.

Socioeconomic inequality in congenital heart diseases in Iran

INTRODUCTION

Social-economic factors have an important role in shaping inequality in congenital heart diseases. The current study aimed to assess and decompose the socio-economic inequality in Congenital Heart Diseases (CHDs) in Iran.

METHODS

This is a cross-sectional research conducted at Shahid Rajaie Cardiovascular Medical and Research Center in Tehran, Iran, as one of the largest referral heart hospitals in Asia. Data were collected primarily from 600 mothers who attended in pediatric cardiology department in 2020. The polychoric principal component analysis (PCA) and Errygers corrected CI (ECI) were used to construct household socioeconomic status and to assess inequality in CHDs, respectively. A regression-based decomposition analysis was also applied to explain socioeconomic-related inequalities. To select the explanatory social, medical/biological, and lifestyle variables, the chi-square test was first used.

RESULTS

There was a significant pro-rich inequality in CHDs (ECI = -0.65, 95% CI, - 0.72 to - 0.58). The social, medical/biological, and lifestyle variables accounted for 51.47, 43.25, and 3.92% of inequality in CHDs, respectively. Among the social variables, family SES (about 50%) and mother's occupation (21.05%) contributed the most to CHDs' inequality. Besides, in the medical/biological group, receiving pregnancy care (22.06%) and using acid folic (15.70%) had the highest contribution.

CONCLUSION

We concluded that Iran suffers from substantial socioeconomic inequality in CHDs that can be predominantly explained by social and medical/biological variables. It seems that distributional policies aim to reduce income inequality while increasing access of prenatal care and folic acid for disadvantaged mothers could address this inequality much more strongly in Iran.

Assessing Health and Wellness Outcomes of Medicaid-Enrolled Infants Born to Adolescent Mothers

OBJECTIVE

To assess the effect of adolescent birth on the health and wellness of these infants within their first year of life.

METHODS

Our study focused on 2011 Medicaid births nationwide. The study group (infants born to adolescents, aged 10 to 19 at time of birth) was matched with infants born to adults (aged 20 to 44 at time of birth), based on demographics. Statistical tests (proportion test and Poisson test) were used to compare the outcomes of these two groups to determine if differences were significant.

RESULTS

The outcomes assessed were: low birth weight (LBW), substance exposure, foster care, health status, infant mortality, emergency department (ED) visits, and wellness visits. Of the 68,562 infant pairs included in the study, we found statistically significant higher rates of LBW (P ≤ 0·005), infant mortality (P = 0·05), and ED visits (P ≤ 0·005) for infants born to adolescents at the 95% confidence interval. The rate of wellness visits for all infants was well below the recommended amount. Additional differences were found at the race/ethnicity and urbanicity levels.

CONCLUSION FOR PRACTICE

Infants born to adolescents had a higher rate of ED visits within the first year of life, however, the increased rates of LBW and mortality for the Medicaid population are not as significant as previous national studies suggest. Analysis of outcomes across stratification helped identify vulnerable populations (i.e. urban infants). Public health programs are urged to examine ED visits in infants born to adolescents among the Medicaid population. Improved health education or phone-based resources could help reduce unnecessary visits and reduce cost.

Higher Marijuana use among Young Adults Persists Even during Pregnancy

Background

Marijuana is linked to adverse pregnancy health effects, yet limited data exist regarding demographic and regional differences in marijuana use during pregnancy.

Objective

To determine the prevalence of prenatal marijuana use among reproductive-age women and assess regional and age-related differences.

Methods

This study secondarily analyzed cross-sectional, population-based Pregnancy Risk Assessment Monitoring System data from states querying about marijuana use. It included 10,350 women with live births in 2009-2011. Primary outcome was "any use of marijuana" during pregnancy. Logistic regression analysis examined associations between marijuana use, age, and other socio demographic characteristics.

Results

In all states, marijuana use during pregnancy was more likely in adolescent and young adults (AYA; <25 years) than older mothers: Alaska, prevalence rate ratio (PRR), 2.07 (95% confidence interval [CI], 1.5-2.6); Hawaii, PRR, 1.55 (95% CI, 1.2-1.9); Vermont, PRR, 2.44 (95% CI, 1.9-2.9). Regression analyses, controlling for other demographic characteristics, showed that age <25 was associated with higher odds of marijuana use in Alaska (adjusted odds ratio [aOR], 2.24 [95% CI, 1.9-2.5]) and Vermont (aOR, 1.74 [95% CI, 1.5-1.9]). Smoking cigarettes during pregnancy was associated with higher odds of concomitant marijuana use in Alaska (aOR, (P<0.05)) and Vermont (aOR, 1.2 (P<0.05)).

Conclusions

AYA reported higher marijuana use rates during pregnancy than older women. Cigarette use during pregnancy was associated with marijuana use. Additional research, examining national marijuana use patterns and maternal and child health outcomes in the context of evolving marijuana policies, is warranted.

Providing maternity care for disadvantaged women in Aotearoa New Zealand: The impact on midwives

BACKGROUND

Health inequities and socio-economic disadvantage are causes for concern in Aotearoa New Zealand. Becoming pregnant can increase a woman's vulnerability to poverty, with the potential for an increase in multiple stressful life events. Providing midwifery care to women living in socio-economic deprivation has been found to add additional strains for midwives. Exploring the perspectives of the midwives providing care to women living with socio-economic deprivation can illuminate the complexities of maternity care.

AIM

To explore the impact on midwives when providing care for socio-economically disadvantaged women in Aotearoa New Zealand.

METHOD

Inductive thematic analysis was used to analyse an open-ended question from a survey that asked midwives to share a story around maternal disadvantage and midwifery care.

FINDINGS

A total of 214 stories were received from midwives who responded to the survey. Providing care to disadvantaged women had an impact on midwives by incurring increased personal costs (time, financial and emotional), requiring them to navigate threats and uncertainty and to feel the need to remedy structural inequities for women and their wider families. These three themes were moderated by the relationships midwives held with women and affected the way midwives worked across the different maternity settings.

CONCLUSION

Midwives carry a greater load when providing care to socio-economically deprived women. Enabling midwives to continue to provide the necessary support for women living in socio-economic deprivation is imperative and requires additional resources and funding.

Secondhand Smoke Exposure during Pregnancy and its Effect on Birth Outcomes: Evidence from a Retrospective Cohort Study in a Tertiary Care Hospital in Bengaluru

Context:

The effect of maternal smoking on birth outcomes is well-established, but the effect of maternal secondhand smoke (SHS) exposure is less clear, especially among Indian women.

Aim:

To evaluate the effect of SHS exposure during pregnancy on birth outcomes such as gestational age at birth, neonatal anthropometry, and Apgar score.

Setting and Design:

Retrospective cohort study at a tertiary hospital in Bengaluru.

Methods:

208 postnatal mothers: 104 each in “exposed” and “nonexposed” group, based on the history of SHS exposure during pregnancy. Sociodemographic and obstetric details were obtained by interview schedule and birth outcomes were obtained from patient charts.

Statistical Analysis:

Association of SHS exposure with birth outcomes was analyzed using inferential statistics such as Chi-square, t-test, and Mann–Whitney U-test, whereas the strength of association was expressed as relative risk with 95% confidence intervals. P < 0.05 was considered statistically significant.

Results:

SHS exposed and nonexposed groups were comparable with regard to potentially confounding socioeconomic and obstetric covariates. Babies born to SHS-exposed mothers had significantly lower mean birth weight, mean birth length, and mean birth head circumference by 172.5 g (P = 0.027), 1.6 cm (P = 0.001), and 1.1 cm (P = 0.001), respectively.

Conclusion:

Mothers exposed to SHS during pregnancy were twice likely to deliver low birth weight babies (relative risk [RR] = 1.9 [1.0–3.6], P = 0.02) and babies of low birth length (RR = 2.64 [1.4–4.6], P = 0.001) than unexposed mothers. With a significant risk of adverse birth outcomes found among mothers exposed to SHS during pregnancy, it is important that a “no tobacco smoke” environment at home should be recommended for pregnant women and their families.

Neighbourhood maternal socioeconomic status indicators and risk of congenital heart disease

BACKGROUND

This study aimed to examine the relationships between various maternal socioeconomic status (SES) indicators and the risk of congenital heart disease (CHD).

METHODS

This was a population-based retrospective cohort study, including all singleton stillbirths and live births in Ontario hospitals from April 1, 2012 to March 31, 2018. Multivariable logistic regression models were performed to examine the relationships between maternal neighbourhood household income, poverty, education level, employment and unemployment status, immigration and minority status, and population density and the risk of CHD. All SES variables were estimated at a dissemination area level and categorized into quintiles. Adjustments were made for maternal age at birth, assisted reproductive technology, obesity, pre-existing maternal health conditions, substance use during pregnancy, rural or urban residence, and infant's sex.

RESULTS

Of 804,292 singletons, 9731 (1.21%) infants with CHD were identified. Compared to infants whose mothers lived in the highest income neighbourhoods, infants whose mothers lived in the lowest income neighbourhoods had higher likelihood of developing CHD (adjusted OR: 1.29, 95% CI: 1.20-1.38). Compared to infants whose mothers lived in the neighbourhoods with the highest percentage of people with a university or higher degree, infants whose mothers lived in the neighbourhoods with the lowest percentage of people with university or higher degree had higher chance of CHD (adjusted OR: 1.34, 95% CI: 1.24-1.44). Compared to infants whose mothers lived in the neighbourhoods with the highest employment rate, the odds of infants whose mothers resided in areas with the lowest employment having CHD was 18% higher (adjusted OR: 1.18, 95% CI: 1.10-1.26). Compared to infants whose mothers lived in the neighbourhoods with the lowest proportion of immigrants or minorities, infants whose mothers resided in areas with the highest proportions of immigrants or minorities had 18% lower odds (adjusted OR: 0.82, 95% CI: 0.77-0.88) and 16% lower odds (adjusted OR: 0.84, 95% CI: 0.78-0.91) of CHD, respectively.

CONCLUSION

Lower maternal neighbourhood household income, poverty, lower educational level and unemployment status had positive associations with CHD, highlighting a significant social inequity in Ontario. The findings of lower CHD risk in immigrant and minority neighbourhoods require further investigation.

The Changing Aspects of Motherhood in Face of the COVID-19 Pandemic in Low- and Middle-Income Countries

Purpose

To advocate perspectives to strengthen existing healthcare systems to prioritize maternal health services amidst and beyond the COVID-19 pandemic in low- and middle income countries.

Description

COVID-19 directly affects pregnant women causing more severe disease and adverse pregnancy outcomes. The indirect effects due to the monumental COVID-19 response are much worse, increasing maternal and neonatal mortality.

Assessment

Amidst COVID-19, governments must balance effective COVID-19 response measures while continuing delivery of essential health services. Using the World Health Organization’s operational guidelines as a base, countries must conduct contextualized analyses to tailor their operations. Evidence based information on different services and comparative cost-benefits will help decisions on trade-offs. Situational analyses identifying extent and reasons for service disruptions and estimates of impacts using modelling techniques will guide prioritization of services. Ensuring adequate supplies, maintaining core interventions, expanding non-physician workforce and deploying telehealth are some adaptive measures to optimize care. Beyond the COVID-19 pandemic, governments must reinvest in maternal and child health by building more resilient maternal health services supported by political commitment and multisectoral engagement, and with assistance from international partners.

Conclusions

Multi-sectoral investments providing high-quality care that ensures continuity and available to all segments of the population are needed. A robust primary healthcare system linked to specialist care and accessible to all segments of the population including marginalized subgroups is of paramount importance. Systematic approaches to digital health care solutions to bridge gaps in service is imperative. Future pandemic preparedness programs must include action plans for resilient maternal health services.

Sociodemographic characteristics associated with the utilization of maternal health services in Cambodia

Background

Cambodia is a Southeast Asian country and has one the highest rates of maternal and child mortality with inadequate use of maternal healthcare services in the region. The present study aimed to analyse the progress made in terms of using maternal healthcare services since 2000.

Methods

Two rounds of Demographic and Health Surveys (DHS 2000 and DHS 2014) were used in the study. Sample population consisted 11,961 women aged between 15 and 49 years. The outcome measures were: Timing of first antenatal care (ANC) attendance, adequacy of ANC attendance, place of delivery and postnatal checkup. WHO guidelines were used to set the cut-off/define these measures. Data were analyzed in Stata version 14 using descriptive and multivariate regression analyses.

Results

Findings indicated that the overall prevalence of making the first ANC visit in the first trimester was 64.19% [95%CI = 62.22,66.11], and that of having at least four ANC visits was 43.80% [95%CI = 41.89,45.73]. Prevalence of health facility delivery was 48.76% [46.62,50.90] and that of postnatal checkup was 71.14% [95%CI = 69.21,73.01]. Between 2000 and 2014, the percentage of timely and adequate use of ANC increased by respectively 61.8 and 65.3%, while that of health facility delivery and postnatal care increased by respectively 74.5 and 43.9%. Important demographic, socioeconomic and geographic disparities were observed in the utilization of ANC, health facility delivery and postnatal care services. Urban residency, having better educational status, white collar job, access to electronic media showed positive association, whereas higher parity (having > 2 children) and unwanted pregnancy showed negative association with the use of maternal healthcare services. Having at least four ANC visits was associated with significantly increased higher odds of using health facility delivery and postnatal care.

Conclusion

There has a been a remarkable increase in the prevalence of women who are using the maternal healthcare services since 2000. The current findings provide important insights regarding the sociodemographic factors associated with the utilization of maternal health services in Cambodia that could contribute to evidence-based health policy making and designing intervention programs.

Influence of Family Income Level on Obstetric and Perinatal Outcomes in Spain

For pregnant women, having a low family income status is associated with late prenatal attendance and an increased risk of adverse outcomes during pregnancy, delivery, and immediately after delivery. However, the influence of the socioeconomic level on maternal and child health may be minimal as long as the health system model is able to neutralise health inequity. For this reason, the objective of this study is to determine the relationship between the socioeconomic level assessed through monthly household income and obstetric and perinatal outcomes in the Spanish Health System, where midwives play a relevant role. To meet this objective, a cross-sectional observational study aimed at women who have been mothers between 2013 and 2018 in Spain was developed. The final study population was 5942 women. No statistically significant differences with linear trend were found between income level and obstetric and perinatal outcomes after the adjustment by confounding factors (pregnancy composite morbidity, p = 0.447; delivery composite morbidity, p = 0.590; perinatal composite morbidity, p = 0.082; postpartum composite morbidity, p = 0.407). The main conclusion is that, in the current Spanish health system, household income as an indicator of socioeconomic status is not related to perinatal outcomes after the adjustment by confounding factors. These results are likely due to the public model of our health system that serves all citizens on equal footing, although other social and individual factors may have influenced these results

Postpartum environmental challenges alter maternal responsiveness and offspring development

Because many threats exist in an animal's natural habitat, it is important to understand the impact of environmental challenges on maternal-offspring interactions and outcomes. In the current study, a rodent model incorporating the presence of restricted resources and an environmental threat (e.g. predator-related odors and sounds) was investigated. Specifically, pregnant females were assigned to one of four treatments: standard resources, without threat (SR; n = 7); standard resources plus threat (SR-T; n = 8); restricted resources, without threat (RR; n = 7); and restricted resources plus threat (RR-T; n = 6). Maternal rats were moved into the assigned conditions on postnatal day 2 and remained until pups were weaned. Following a standard pup retrieval task on postnatal days 2 and 6, maternal rats were exposed to a retrieval challenge task on postnatal day 8 in which each rat had to traverse a novel barrier to retrieve pups. For neurobiological measures of stress/resilience responsiveness, fecal samples were collected for detection of corticosterone and DHEA metabolites; additionally, immunohistochemistry was conducted on the maternal brains to indicate the presence of Neuropeptide Y (NPY) and Brain Derived Neurotrophic Factor (BDNF) immunoreactivity in the hippocampus, amygdala and hypothalamus. Pup development measures, including body weight and tail length, were also collected. Results suggest that maternal rats with restricted resources exhibited diminished maternal responsiveness that resulted in altered pup development measures; further, restricted resource rats exhibited endocrine markers of compromised emotional resilience (lower DHEA) and decreased neural markers of neuroplasticity (BDNF) and emotional resilience (NPY). Interestingly, predator threat affected various aspects of maternal-pup interactions but had no effect on neurobiological variables, suggesting that restricted resources had a more negative impact on maternal-related outcomes than the presence of predator threat.

State- and county-level income inequality and infant mortality in the USA in 2010: a cohort study

OBJECTIVES

We examined the relationship between income inequality and the risk for infant/neonatal mortality at the state and county level and tested possible mediators of this relationship.

METHODS

We first linked state and county Gini coefficients to US Vital Statistics 2010 Cohort Linked Birth and Infant Death records (n = 3,954,325). We then fit multilevel models to test whether income inequality was associated with infant/neonatal mortality. County-level factors were tested as potential mediators.

RESULTS

Adjusted analyses indicated that income inequality at the county level-but not at the state level-was associated with increased odds of infant mortality (OR 1.14, 95% CI 1.10, 1.18) and neonatal death (OR 1.17, 95% CI 1.12, 1.23). Our mediators explained most of this variation. Bivariate analyses revealed associations between 3 county-level measures-patient-to-physician ratio, the violent crime rate, and sexually transmitted infection rate-and infant and neonatal mortality. Proportion of college-educated adults was associated with decreased odds for neonatal mortality.

CONCLUSIONS

Local variations in access to care, the rate of sexually transmitted disease, and crime are associated with infant mortality, while variations in college education in addition to these mediators explain neonatal mortality. To reduce infant and neonatal mortality, experiments are needed to examine the effectiveness of policies targeted at reducing income inequality and improving healthcare access, policing, and educational opportunities.

Muslim women's experiences of maternity services in the UK: qualitative systematic review and thematic synthesis

BACKGROUND

This review aimed to identify and synthesise evidence of Muslim women's experiences of maternity services in the UK. A systematic review and thematic synthesis of qualitative evidence, unrestricted by type of publication was conducted. Muslim women who had accessed maternity services in the UK, regardless of obstetric or medical history were included.

METHOD

Databases were searched from 2001 to 2019 and screened for inclusion using pre-determined criteria. The Critical Appraisal Skills Programme Qualitative Research Checklist was used to assess study quality and findings were synthesised using thematic synthesis, as described by Thomas and Harden.

RESULTS

Six studies were included. The following five themes were identified: Islamic practices and Individualised care; Talk, Teach and Translate; Injustice, Inequity and Intolerance; If Allah wills; and, 'It's not all that bad'. Synthesis highlighted the significance of Islam in shaping many of the women's decision-making relating to antenatal screening and medication, which was contrasted with healthcare professionals' limited awareness of the importance of Islam for motherhood. The majority of women experienced poor maternity care which at times indicated stereotypical and discriminatory behaviour.

CONCLUSIONS

Education for healthcare professionals is warranted, to enhance the quality and cultural competency in providing appropriate care that acknowledges and meets Muslim women's needs.

Structural Racism and Odds for Infant Mortality Among Infants Born in the United States 2010

OBJECTIVES

While ecological studies indicate that high levels of structural racism within US states are associated with elevated infant mortality rates, studies using individual-level data are needed. To determine whether indicators of structural racism are associated with the individual odds for infant mortality among white and black infants in the US.

METHODS

We used data on 2,163,096 white and 590,081 black infants from the 2010 US Cohort Linked Birth/Infant Death Data Files. Structural racism indicators were ratios of relative proportions of blacks to whites for these domains: electoral (registered to vote and voted; state legislature representation), employment (civilian labor force; employed; in management; with a bachelor's degree), and justice system (sentenced to death; incarcerated). Multilevel logistic regression was used to determine whether structural racism indicators were risk factors of infant mortality.

RESULTS

Compared to the lowest tertile ratio of relative proportions of blacks to whites with a bachelor's degree or higher-indicative of low structural racism-black infants, but not whites, in states with moderate (OR = 1.12, 95% CI = 0.94, 1.32) and high tertiles (OR = 1.25, 95% CI = 1.03, 1.51) had higher odds of infant mortality.

CONCLUSIONS

Educational and judicial indicators of structural racism were associated with infant mortality among blacks. Decreasing structural racism could prevent black infant deaths.

Differential relationship between state-level minimum wage and infant mortality risk among US infants born to white and black mothers

BACKGROUND

Compared to other Organisation for Economic Co-operation and Development (OECD) nations, US infant mortality rates (IMRs) are particularly high. These differences are partially driven by racial disparities, with non-Hispanic black having IMRs that are twice those of non-Hispanic white. Income inequality (the gap between rich and poor) is associated with infant mortality. One proposed way to decrease income inequality (and possibly to improve birth outcomes) is to increase the minimum wage. We aimed to elucidate the relationship between state-level minimum wage and infant mortality risk using individual-level and state-level data. We also determined whether observed associations were heterogeneous across racial groups.

METHODS

Data were from US Vital Statistics 2010 Cohort Linked Birth and Infant Death records and the 2010 US Bureau of Labor Statistics. We fit multilevel logistic models to test whether state minimum wage was associated with infant mortality. Minimum wage was standardised using the z-transformation and was dichotomised (high vs low) at the 75th percentile. Analyses were stratified by mother's race (non-Hispanic black vs non-Hispanic white).

RESULTS

High minimum wage (adjusted OR (AOR)=0.93, 95% CI 0.83 to 1.03) was associated with decreased odds of infant mortality but was not statistically significant. High minimum wage was significantly associated with reduced infant mortality among non-Hispanic black infants (AOR=0.80, 95% CI 0.68 to 0.94) but not among non-Hispanic white infants (AOR=1.04, 95% CI 0.92 to 1.17).

CONCLUSIONS

Increasing the minimum wage might be beneficial to infant health, especially among non-Hispanic black infants, and thus might decrease the racial disparity in infant mortality.

The Effectiveness of Different Doses of Iron Supplementation and the Prenatal Determinants of Maternal Iron Status in Pregnant Spanish Women: ECLIPSES Study

Iron deficiency (ID), anemia, iron deficiency anemia (IDA) and excess iron (hemoconcentration) harm maternal–fetal health. We evaluated the effectiveness of different doses of iron supplementation adjusted for the initial levels of hemoglobin (Hb) on maternal iron status and described some associated prenatal determinants. The ECLIPSES study included 791 women, randomized into two groups: Stratum 1 (Hb = 110–130g/L, received 40 or 80mg iron daily) and Stratum 2 (Hb > 130g/L, received 20 or 40mg iron daily). Clinical, biochemical, and genetic information was collected during pregnancy, as were lifestyle and sociodemographic characteristics. In Stratum 1, using 80 mg/d instead of 40 mg/d protected against ID on week 36. Only women with ID on week 12 benefited from the protection against anemia and IDA by increasing Hb levels. In Stratum 2, using 20 mg/d instead of 40 mg/d reduced the risk of hemoconcentration in women with initial serum ferritin (SF) ≥ 15 μg/L, while 40 mg/d improved SF levels on week 36 in women with ID in early pregnancy. Mutations in the HFE gene increased the risk of hemoconcentration. Iron supplementation should be adjusted to early pregnancy levels of Hb and iron stores. Mutations of the HFE gene should be evaluated in women with high Hb levels in early pregnancy.

Racial Differences and Factors Associated with Pregnancy in ESKD Patients on Dialysis in the United States

BACKGROUND

Pregnancy in women with ESKD undergoing dialysis is uncommon due to impaired fertility. Data on pregnancy in women on dialysis in the United States is scarce.

METHODS

We evaluated a retrospective cohort of 47,555 women aged 15-44 years on dialysis between January 1, 2005 and December 31, 2013 using data from the United States Renal Data System with Medicare as primary payer. We calculated pregnancy rates and identified factors associated with pregnancy.

RESULTS

In 47,555 women on dialysis, 2352 pregnancies were identified. Pregnancy rate was 17.8 per thousand person years (PTPY) with the highest rate in women aged 20-24 (40.9 PTPY). In the adjusted time-to-event analysis, a higher likelihood of pregnancy was seen in Native American (HR, 1.77; 95% CI, 1.33 to 2.36), Hispanic (HR, 1.51; 95% CI, 1.32 to 1.73), and black (HR, 1.33; 95% CI, 1.18 to 1.49) women than in white women. A higher rate of pregnancy was seen in women with ESKD due to malignancy (HR, 1.64; 95% CI, 1.27 to 2.12), GN (HR, 1.38; 95% CI, 1.21 to 1.58), hypertension (HR, 1.32; 95% CI, 1.16 to 1.51), and secondary GN/vasculitis (HR, 1.18; 95% CI, 1.02 to 1.37) than ESKD due to diabetes. A lower likelihood of pregnancy was seen among women on peritoneal dialysis than on hemodialysis (HR, 0.47; 95% CI, 0.41 to 0.55).

CONCLUSIONS

The pregnancy rate is higher in women on dialysis than previous reports indicate. A higher likelihood of pregnancy was associated with race/ethnicity, ESKD cause, and dialysis modality.

Poor mothers, unhealthy children: the transmission of health inequalities in the INMA study, Spain

BACKGROUND

The health of pregnant women and their fetuses are especially sensitive to socioeconomic conditions. This study analyzes the impact of maternal socioeconomic status (SES), evaluated by occupation and maternal education level, in preterm births (PTBs) and in small for gestational age (SGA) fetuses, considering the effect of the potential mediating factors on the SES and birth outcomes.

METHODS

A total of 2497 mother/newborn dyads from the INMA-Spain project were studied. We examined maternal occupation and education in relation to PTB and SGA along with covariate data, using logistic regression analysis. Adjusted models for each of the outcome variables in relation to SES indicators were estimated, considering potential mediating factors.

RESULTS

About 4.7% of babies were PTB and 9.7% SGA. Full adjusted logistic regression models showed similar odds ratio (OR) for SGA in both SES indicators. Manual working women or without university studies had higher risk of SGA than their counterpart groups (OR = 1.39% CI = 1.03-1.88 and OR = 1.39% CI = 1.00-2.00, respectively). Likewise, mothers with a manual occupation were at more risk of PTB than those with a non-manual occupation (OR = 1.74 95% CI = 1.13-2.74), but there was no association between education and PTB. Smoking, pre-pregnancy BMI and underweight gain during pregnancy were significantly associated to SGA births. The mother's age, presence of complications and overweight gain during pregnancy were related to PTB.

CONCLUSION

The mother's socioeconomic disadvantage was consistently associated with birth outcomes giving rise to intergenerational transmission of health inequalities. Reducing inequalities requires eliminating the upstream causes of poverty itself.

Maternal adverse childhood experiences and antepartum risks: the moderating role of social support

The aims of the current study were to examine the association between maternal adverse childhood experiences (ACEs) and antepartum health risks, and to investigate whether social support moderated this association. It was hypothesized that ACEs would be associated with antepartum health risks; however, social support in the prenatal period would buffer mothers from the deleterious consequences of ACEs. Data from 1994 women (mean age = 31 years) and their infants were collected from a longitudinal cohort recruited in health care offices in Alberta, Canada. Pregnant women completed questionnaires related to ACEs prior to the age of 18 and prenatal social support, and a health care professional assessed the mother's antepartum health risk. ACEs included physical, emotional, and sexual abuse, exposure to domestic violence, as well as exposure to household dysfunction such as parental substance use, mental illness, or incarceration. Regression analyses demonstrated a positive association between ACEs and antepartum health risks. However, a significant interaction between maternal ACEs and social support was also observed. Specifically, women exposed to high ACEs and low social support in pregnancy had high antepartum health risks. However, among mothers who had high ACEs but also high levels of social support, there was no association between ACEs and antepartum health risk. A history of ACEs can place mothers at risk of antepartum health complications. However, a resiliency effect was observed: women with a history of ACEs were buffered from experiencing antepartum health risks if they reported high levels of social support in pregnancy.

Psychosocial Factors Associated with Healthy and Unhealthy Interpregnancy Intervals

Purpose: To examine the influence of psychosocial factors, including anxiety, depression, social support, maternal substance abuse, and intimate partner violence (IPV) on interpregnancy intervals (IPIs).

Methods: B'more for Healthy Babies–Upton/Druid Heights is part of a citywide initiative to improve the health of at-risk pregnant women and their children. Participants with at least one prior birth completed baseline, postpartum, and 3-month follow-up surveys with questions about pregnancy, medical, and psychosocial history. Associations between IPI and the independent variables were assessed using chi-square analysis and analysis of variance. Multivariable multinomial logistic regression models examined significant associations while controlling for other independent variables and potential confounders.

Results: Participants with current IPV were more likely to have a short IPI (odds ratio [OR]=13.1; 95% confidence interval [CI]=1.07–158.9; p=0.04) than healthy IPI. Women with family social support were more likely to have a healthy IPI (OR=5.88, 95% CI=1.02–31.25, p=0.05) than those without family social support. Maternal anxiety and depression did not significantly influence IPI.

Conclusion: IPV increased the likelihood of having an unhealthy IPI among this population and family social support increased the likelihood of having a healthy IPI. Additional efforts to address IPV and enhance family social support may lead to improved pregnancy outcomes.

Prevalence of low birth weight and its association with maternal body weight status in selected countries in Africa: a cross-sectional study

OBJECTIVES

The present study aimed to estimate the prevalence of low birth weight (LBW), and to investigate the association between maternal body weight measured in terms of body mass index (BMI) and birth weight in selected countries in Africa.

SETTING

Urban and rural household in Burkina Faso, Ghana, Malawi, Senegal and Uganda.

PARTICIPANTS

Mothers (n=11 418) aged between 15 and 49 years with a history of childbirth in the last 5 years.

RESULTS

The prevalence of LBW in Burkina Faso, Ghana, Malawi, Senegal and Uganda was, respectively, 13.4%, 10.2%, 12.1%, 15.7% and 10%. Compared with women who are of normal weight, underweight mothers had a higher likelihood of giving birth to LBW babies in all countries except Ghana. However, the association between maternal BMI and birth weight was found to be statistically significant for Senegal only (OR=1.961 (95% CI 1.259 to 3.055)).

CONCLUSION

Underweight mothers in Senegal share a greater risk of having LBW babies compared with their normal-weight counterparts. Programmes targeting to address infant mortality should focus on promoting nutritional status among women of childbearing age. Longitudinal studies are required to better elucidate the causal nature of the relationship between maternal underweight and LBW.

Childbirth-Related Hospital Burden by Socioeconomic Status in a Universal Health Care Setting

INTRODUCTION

Hospital utilization varies across socioeconomic and demographic strata in Canada, a country with a universal health care system. Rates of adverse birth outcomes are known to differ among women of high and low socioeconomic status (SES), but less is known of the excess hospital burden related to SES over the course of childbirth across Canadian provinces.

OBJECTIVE

To examine length of stay and risk of hospitalization surrounding delivery, relative to women's socio-demographic characteristics.

METHODS

A population-based record linkage between the Canadian Community Health Survey (CCHS) years 2005-2011 and the Discharge Abstract Database (DAD) allowed the tracking of hospital utilization for linked survey respondents between 2005 and 2011. Hourly length of stay for delivery, risk of readmission, and risk of admission prior to delivery was modeled by socio-demographic factors, controlling for other clinical and individual-level characteristics.

RESULTS

There were 21,914 complete delivery records from 15,458 female CCHS respondents who agreed to link and share their information. Average length of stay (for both vaginal and Caesarian deliveries) dropped over the study period from 67.86 hours in 2005 to 59.37 hours in 2011. In multivariate analyses, women with the lowest income had on average, two-hour longer stays for vaginal delivery as compared to high-income women (IRR 1.04, 95% CI 1.00-1.08) and higher risk of admission prior to delivery (OR 1.43, CI 1.13-1.81). Low-income women, Aboriginal women and women living in rural areas were also at elevated risk for longer hospital stays and for hospital admission prior to delivery. There was no consistent socioeconomic patterning of hospital burden for Caesarian deliveries.

CONCLUSION

The length of hospital stays for childbirth has declined in Canada. Length of stay remains modestly longer, and risk of hospitalization in the perinatal period higher, for low income women, Aboriginal women and rural women. The absence of egregious income-related differences in hospital burden related to childbirth is reassuring for the equity goals of the Canadian health care system. The persistence of marginally longer, and in turn, costlier visits for low-income and Aboriginal women before and during delivery is, however, suggestive that resources targeted to the prenatal period might be highly cost-effective if they achieve population-wide reductions in length of stay and hospitalization in the perinatal period.

Adaptive Behavior of Sheltered Homeless Children in the French ENFAMS Survey

OBJECTIVES

To describe the adaptive behaviors in a large sample of homeless children and identify factors associated with developmental delay.

METHODS

Data were from a cross-sectional survey of 557 children younger than 6 years randomly sampled among homeless sheltered families in the Paris region, France (January-May 2013). An interviewer and a psychologist conducted face-to-face interviews to collect information on sociodemographic and health characteristics. We assessed adaptive behaviors using the Vineland Adaptive Behavior Scales, second edition (VABS-II).

RESULTS

The mean VABS-II composite score (SD) was 75.4 (12.0), and most participating children (80.9%) were considered developmentally delayed. Characteristics negatively associated with children's developmental score were age, birth in a country other than France, low birth weight, and past-year hospitalization.

CONCLUSIONS

There is a high prevalence of developmental delays among children growing up homeless. Public Health Implications. Long-term integrated programs improving parenting and children's opportunities for stimulation and socialization should be developed in daycare centers, schools, shelters, and medical practices to minimize negative effects of early living conditions on children's development.

Differential Effects of the Single-Family Room Neonatal Intensive Care Unit on 18- to 24-Month Bayley Scores of Preterm Infants

OBJECTIVES

To determine the effects of human milk and social/environmental disparities on developmental outcomes of infants born preterm cared for in a single-family room (SFR) neonatal intensive care unit (NICU).

STUDY DESIGN

Outcomes were compared between infants weighing ?1250 g cared for in an open-bay NICU (1/2007-8/2009) (n?=?394) and an SFR NICU (1/2010-12/2011) (n?=?297). Human milk provision at 1 week, 4 weeks and discharge, and 4 week volume (mL/kg/day) were analyzed. At 18-24 months of age, the Bayley III was administered. Group differences were evaluated and multiple linear regression analyses were run.

RESULTS

Infants cared for in the SFR NICU had higher Bayley III cognitive and language scores, higher rates of human milk provision at 1 and 4 weeks, and higher human milk volume at 4 weeks. In adjusted regression models, the SFR NICU was associated with a 2.55-point increase in Bayley cognitive scores and 3.70-point increase in language scores. Every 10?mL/kg/day increase of human milk at 4 weeks was independently associated with increases in Bayley cognitive, language, and motor scores (0.29, 0.34, and 0.24, respectively). Medicaid was associated with decreased cognitive (?4.11) and language (?3.26) scores, and low maternal education and non-white race with decreased language scores (?4.7 and ?5.8, respectively). Separate models by insurance status suggest there are differential benefits from SFR NICU and human milk between infants with Medicaid and private insurance.

CONCLUSIONS

Infants born preterm cared for in the SFR NICU have higher Bayley language and cognitive scores and receive more human milk. Independent effects on outcomes were derived from SFR NICU, provision of human milk, and social and environmental factors.

Gestational age and chronic 'body-mind' health problems in childhood: dose-response association and risk factors

Understanding the developmental course of all health issues associated with preterm birth is important from an individual, clinical and public health point-of-view. Both the number of preterm births and proportion of survivors have increased steadily in recent years. The UK Millennium Cohort Study (n = 18,818) was used to examine the association of gestational age with maternal ratings of general health and behavior problems at ages 5 and 11 years using binary and multinomial logistic regression analyses. The association between mothers' ratings of general health and behavior problems was relatively weak at each time point. Children rated as being in poor general health remained constant over time (4.0 % at age 5, 3.8 % at age 11), but children rated as having behavioral problems increased by almost 100 % (5.6 % at 5; 10.5 % at 11). A gradient of increasing risk with decreasing gestational age was observed for a composite health measure (general health problems and/or behavior problems) at age 5, amplified at age 11 and was strongest for those with chronic problems (poor health at both age 5 and age 11). This association was found to be compounded by child sex, maternal characteristics at birth (education, employment, marital status) and duration of breast feeding. Integrated support to at-risk families initiated during, or soon after pregnancy, may prevent chronic problems and might potentially reduce long term health costs for both the individual and health services.

Targeting factors for change: contraceptive counselling and care of female adolescents

INTRODUCTION

Sexual and reproductive health care should empower and enable all individuals to have a sex life that is as safe and pleasurable as possible. Achievement of this goal for adolescents is often impeded by regional and sociocultural barriers.

OBJECTIVES

To review global barriers to provision of effective counselling and care of adolescents seeking advice on contraception and sexual and reproductive health and identify elements of best practice that can be adapted to meet their needs at regional level.

METHODS

Experts with clinical experience and a scholarly background in the provision of contraceptive services to adolescents participated in a stepwise process of literature review and discussion according to the agreed objectives.

RESULTS

The Global CARE (Contraception: Access, Resources, Education) group identified barriers to the access, availability and acceptance of contraception by adolescents, not only at the political and sociocultural level but also within health care practice. The group collected and summarized successful local strategies and tools suitable for adaptation in other regions. Elements of best practice for providing contraception regardless of setting or regional constraints, including required skills, knowledge, and attitudes, were also proposed.

CONCLUSION

Sharing of evidence-based best practice in delivering contraceptive services, improvements in health care provider education, and sharing of experience between countries will hopefully help to overcome the barriers to appropriate and effective counselling and care of adolescents.

Intellectual Disability in a Birth Cohort: Prevalence, Etiology, and Determinants at the Age of 4 Years

Background

Intellectual disability (ID), characterized by impairments in intellectual function and adaptive behavior, affects 1-3% of the population. Many studies investigated its etiology, but few are cohort studies in middle-income countries.

Aims

To estimate prevalence, etiology, and factors related to ID among children prospectively followed since birth in a Southern Brazilian city (Pelotas).

Methods

In 2004, maternity hospitals were visited daily and births were identified. Live-born infants (n = 4,231) whose family lived in the urban area have been followed for several years. At the age of 2 and 4 years, performances in development and intelligence tests were evaluated using the Battelle Developmental Inventory and Wechsler Intelligence Scale, respectively. Children considered as having developmental delay were invited to attend a genetic evaluation.

Results

At 4 years of age, the prevalence of ID was 4.5%, and the etiology was classified into 5 groups: environmental (44.4%), genetic (20.5%), idiopathic (12.6%), neonatal sequelae (13.2%), other diseases (9.3%). Most children presented impairment in two or more areas of adaptive behavior. There was no difference in prenatal care attendance or maternal schooling among the groups.

Conclusion

For about 40% of children, ID was attributed to nonbiological factors, suggesting that the rate may be reduced with appropriate interventions early in life.
