Postpartum care for parent-infant dyads: A community midwifery model.

INTRODUCTION: Postpartum health is in crisis in the United States, with rising pregnancy-related mortality and worsening racial inequities. The World Health Organization recommends four postpartum visits during the 6 weeks after childbirth, yet standard postpartum care in the United States is generally one visit 6 weeks after birth. We present community midwifery postpartum care in the United States as a model concordant with World Health Organization guidelines, describing this model of care and its potential to improve postpartum health for birthing people and babies. METHODS: We conducted semi-structured interviews with 34 community midwives providing care in birth centers and home settings in Oregon and California. A multidisciplinary team analyzed data using reflexive thematic analysis. RESULTS: A total of 24 participants were Certified Professional Midwives; 10 were certified nurse-midwives. A total of 14 midwives identified as people of color. Most spoke multiple languages. We describe six key elements of the community midwifery model of postpartum care: (1) multiple visits, including home visits; typically five to eight over six weeks postpartum; (2) care for the parent-infant dyad; (3) continuity of personalized care; (4) relationship-centered care; (5) planning and preparation for postpartum; and (6) focus on postpartum rest. CONCLUSION: The community midwifery model of postpartum care is a guideline-concordant approach to caring for the parent-infant dyad and may address rising pregnancy-related morbidity and mortality in the United States.

Pumps: A Possible Tool to Promote More Equitable Lactation Outcomes.

Pregnant individuals and infants in the US are experiencing rising morbidity and mortality rates. Breastfeeding is a cost-effective intervention associated with a lower risk of health conditions driving dyadic morbidity and mortality, including cardiometabolic disease and sudden infant death. Pregnant individuals and infants from racial/ethnic subgroups facing the highest risk of mortality also have the lowest breastfeeding rates, likely reflective of generational socioeconomic marginalization and its impact on health outcomes. Promoting breastfeeding among groups with the lowest rates could improve the health of dyads with the greatest health risk and facilitate more equitable, person-centered lactation outcomes. Multiple barriers to lactation initiation and duration exist for families who have been socioeconomically marginalized by health and public systems. These include the lack of paid parental leave, increased access to subsidized human milk substitutes, and reduced access to professional and lay breastfeeding expertise. Breast pumps have the potential to mitigate these barriers, making breastfeeding more accessible to all interested dyads. In 2012, The Patient Protection and Affordable Care Act (ACA) greatly expanded access to pumps through the preventative services mandate, with a single pump now available to most US families. Despite their near ubiquitous use among lactating individuals, little research has been conducted on how and when to use pumps appropriately to optimize breastfeeding outcomes. There is a timely and critical need for policy, scholarship, and education around pump use given their widespread provision and potential to promote equity for those families facing the greatest barriers to achieving their personal breastfeeding goals.

Civil service organization as a political determinant of health: Analyzing relationships between merit-based hiring, corruption, and population health.

A growing literature finds that the way governments are organized can impact the societies they serve in important ways. The same is apparent with respect to civil service organizations. Numerous studies show that the recruitment of civil servants based on their credentials rather than on nepotism or patronage reduces corruption in government. Political corruption in turn appears to harm population health. Up to this time, however, civil service organization is not a recognized determinant of health and is little discussed outside of political science disciplines. To provoke a broader conversation on this subject, the following study proposes that meritocratic recruitment of civil servants improves population health. To test this proposition, a series of regression models examines comparative data for 118 countries. Consistent with study hypotheses, meritocratic recruitment of civil servants corresponds longitudinally with both lower rates of corruption and lower rates of infant mortality. Results are similar after robustness checks. Findings with regard to life expectancy are more mixed. However, additional tests suggest meritocratic recruitment contributes to life expectancy over a longer span of time. Findings also offer more support for a direct pathway from meritocratic recruitment to population health rather than via changes in corruption levels per se, although this may depend on a country's level of economic development. Overall, this study offers first evidence that civil service organization, particularly the recruitment of civil servants based on the merits of their applications rather than on whom they happen to know in government, is a positive determinant of health. More research in this area is needed.

Bridging the gap between healthcare sectors: Facilitating the transition from NICU to the municipality and home for families with premature infants.

PURPOSE: The transition from hospital to home can be challenging for parents of prematurely born infants. The aim of this ethnographic study was to describe a multidisciplinary and cross-sectoral discharge conference for families with premature infants transitioning from a neonatal intensive care unit to municipal healthcare services. DESIGN AND METHODS: An ethnographically/anthropologically inspired qualitative design was adopted. We conducted four participant observations of multidisciplinary and cross-sectoral discharge conferences and 12 semistructured interviews with four neonatologists, four nurses, and four health visitors who had attended one of the conferences. Salient themes were generated by two-part analysis consisting of a thematic analysis followed by Turner's ritual analysis. RESULTS: This study illustrated how multidisciplinary and cross-sectoral discharge conferences improved the quality of care for premature infants and their families in their transition process which was perceived as complex. These conferences contributed to promoting a sense of coherence and continuity of care. The healthcare professionals experienced that this event may be characterized as a ritual, which created structures that promoted cross-sectoral cooperation and communication while increasing interdisciplinary knowledge sharing. Thus, the conferences triggered a sense that the participants were building bridges to unite healthcare sectors, ensuring a holistic and coordinated approach to meet the unique needs of the infants and their families. IMPLICATIONS FOR PRACTICE: This study presented a unique holistic and family-centered approach to constructing multidisciplinary and cross-sectoral discharge conferences that seemed to underpin the quality of interdisciplinary and health-related knowledge sharing and establish a crucial starting point for early interventions, preventive measures, and health-promoting efforts. Hopefully, our findings will encourage others to rethink the discharge conference as a transitional ritual that may potentially bridge the gap between healthcare sectors. Specifically, our findings contribute to the mounting body of knowledge of family-centered care by showing how healthcare professionals may-in a meaningful and tangible manner-operate, develop, and implement this somewhat elusive theoretical foundation in their clinical practice.

Social inequalities, advanced maternal age, and birth weight. Evidence from a population-based study in Spain.

OBJECTIVE: To examine whether advanced maternal age (≥40 years) is linked to an increased likelihood of low or high birth weight among native and foreign-born mothers giving birth in Spain. METHOD: A cross-sectional study was conducted using a novel database provided by the Spanish National Statistics Office which links the 2011 Census with information on individual births (2011-2015) from the Vital Statistics (Natural Movement of the Population). First, multinomial logistic regression models were used to estimate the potential association between maternal age and the likelihood of having a baby with low or high birth weight. Second, average adjusted predictions of giving birth to children with low, high, and adequate weight for the origin and the maternal age at birth were also calculated. RESULTS: Findings indicate that women with advanced maternal age showed an increased probability of giving birth to low birth weight infants. Conversely, mothers aged below <30 years had an elevated risk for high birth weight infants. When considering maternal migratory status, the findings were mixed. On one hand, foreign-born mothers showed a higher likelihood of delivering infants with high birth weight; on the other, they displayed a lower risk of low birth weight among newborns in comparison to Spanish natives. CONCLUSIONS: The study addresses two key aspects. First, it highlights the increased risk of low birth weight in mothers delivering at an advanced age. Second, it emphasizes the importance of accounting for maternal migratory status when investigating the association between age at birth and birth weight outcomes among immigrant mothers.

An Application of Social Vulnerability Index to Infant Mortality Rates in Ohio Using Geospatial Analysis- A Cross-Sectional Study.

BACKGROUND: Ohio ranks 43rd in the nation in infant mortality rates (IMR); with IMR among non-Hispanic black infants is three times higher than white infants. OBJECTIVE: To identify the social factors determining the vulnerability of Ohio counties to IMR and visualize the spatial association between relative social vulnerability and IMR at county and census tract levels. METHODS: The social vulnerability index (SVICDC) is a measure of the relative social vulnerability of a geographic unit. Five out of 15 social variables in the SVICDC were utilized to create a customized index for IMR (SVIIMR) in Ohio. The bivariate descriptive maps and spatial lag model were applied to visualize the quantitative relationship between SVIIMR and IMR, accounting for the spatial autocorrelation in the data. RESULTS: Southeastern counties in Ohio displayed highest IMRs and highest overall SVIIMR; specifically, highest vulnerability to poverty, no high school diploma, and mobile housing. In contrast, extreme northwestern counties exhibited high IMRs but lower overall SVIIMR. Spatial regression showed five clusters where vulnerability to low per capita income in one county significantly impacted IMR (p = 0.001) in the neighboring counties within each cluster. At the census tract-level within Lucas county, the Toledo city area (compared to the remaining county) had higher overlap between high IMR and SVIIMR. CONCLUSION: The application of SVI using geospatial techniques could identify priority areas, where social factors are increasing the vulnerability to infant mortality rates, for potential interventions that could reduce disparities through strategic and equitable policies.

Community infant safe sleep and breastfeeding promotion and population level-outcomes: A mixed methods study.

PROBLEM: In the U.S., sudden unexpected infant deaths due to accidental suffocation and strangulation in bed are increasing. Though breastfeeding is a protective factor against sudden unexpected infant death, motivations to breastfeed often couple with unsafe infant sleep practices. Racial/ethnic disparities are present in sudden unexpected infant death, accidental suffocation and strangulation in bed, and breastfeeding. BACKGROUND: Promoting infant safe sleep and breastfeeding through community-level initiatives could address disparities in related outcomes. AIM: Investigate the relationship between community-level strategies and associated state-level outcomes for infant safe sleep and breastfeeding. METHODS: We employed an intervention mixed methods framework and exploratory sequential design. The qualitative component entailed a hermeneutical phenomenological framework to analyze key informant interview data from seven U.S. community-level providers participating in a practice improvement initiative. The quantitative component entailed descriptively analyzing infant safe sleep and breastfeeding indicators from the 2019 Pregnancy Risk Assessment Monitoring System and Ohio Pregnancy Assessment Survey. Qualitative and quantitative data were linked through embedded integration. FINDINGS: We identified two mixed insights: gaps in promotion and outcomes, and persistent disparities between infant safe sleep and breastfeeding promotion and outcomes. DISCUSSION: Our findings indicate conversational approaches could improve infant safe sleep and breastfeeding promotion, outcomes, and relative disparities. We find that community collaboration is needed to address organizational capacity limitations in promoting infant safe sleep and breastfeeding. CONCLUSION: Community-level organizations and providers should consider tailoring program offerings and care delivery to include conversational approaches and community collaboration to promote infant safe sleep and breastfeeding and decrease relative disparities in outcomes.

Health equity in Somalia? An evaluation of the progress made from 2006 to 2019 in reducing inequities in maternal and newborn health.

BACKGROUND: Every human being has the right to affordable, high-quality health services. However, mothers and children in wealthier households worldwide have better access to healthcare and lower mortality rates than those in lower-income ones. Despite Somalia's fragile health system and the under-5 mortality rate being among the highest worldwide, it has made progress in increasing reproductive, maternal, and child health care coverage. However, evidence suggests that not all groups have benefited equally. We analysed secondary 2006 and 2018-19 data to monitor disparities in reproductive, maternal, and child health care in Somalia. METHODS: The study's variables of interest are the percentage of contraceptive prevalence through modern methods, adolescent fertility rate, prenatal care, the rate of births attended by midwives, the rate of births in a health care facility, the rate of early initiation of breastfeeding, stunting and wasting prevalence and care-seeking for children under-five. As the outcome variable, we analysed the under-five mortality rate. Using reliable data from secondary sources, we calculated the difference and ratio of the best and worst-performing groups for 2006 and 2018-19 in Somalia and measured the changes between the two. RESULTS: Between 2006 and 2018-19, An increase in the difference between women with high and low incomes was noticed in terms of attended labours. Little change was noted regarding socioeconomic inequities in breastfeeding. The difference in the stunting prevalence between the highest and lowest income children decreased by 20.5 points, and the difference in the wasting prevalence of the highest and the lowest income children decreased by 9% points. Care-seeking increased by 31.1% points. Finally, although under-five mortality rates have decreased in the study period, a marked income slope remains. CONCLUSIONS: The study's findings indicate that Somalia achieved significant progress in reducing malnutrition inequalities in children, a positive development that may have also contributed to the decrease in under-five mortality rate inequities also reported in this study. However, an increase in inequalities related to access to contraception and healthcare for mothers is shown, as well as for care-seeking for sick children under the age of five. To ensure that all mothers and children have equal access to healthcare, it is crucial to enhance efforts in providing essential quality healthcare services and distributing them fairly and equitably across Somalia.

Ecological variation in adult social play reveals a hidden cost of motherhood for wild chimpanzees.

Though common among humans, social play by adults is an uncommon occurrence in most animals, even between parents and offspring.1,2,3 The most common explanation for why adult play is so rare is that its function and benefits are largely limited to development, so that social play has little value later in life.3,4,5,6 Here, we draw from 10 years of behavioral data collected by the Kibale Chimpanzee Project to consider an alternative hypothesis: that despite its benefits, adult play in non-humans is ecologically constrained by energy shortage or time limitations. We further hypothesized that, since they may be the only available partners for their young offspring, mother chimpanzees pay greater costs of play than other adults. Our analysis of nearly 4,000 adult play bouts revealed that adult chimpanzees played both among themselves and with immature partners. Social play was infrequent when diet quality was low but increased with the proportion of high-quality fruits in the diet. This suggests that adults engage in play facultatively when they have more energy and/or time to do so. However, when diet quality was low and most adult play fell to near zero, play persisted between mothers and offspring. Increased use of play by adult chimpanzees during periods of resource abundance suggests that play retains value as a social currency beyond development but that its costs constrain its use. At the same time, when ecological conditions constrain opportunities for young to play, play by mothers fills a critical role to promote healthy offspring development.

Implementing and evaluating group interpersonal therapy for postnatal depression in Lebanon and Kenya-individually randomised superiority trial.

BACKGROUND: Depression ranks as the foremost mental health concern among childbearing women. Within low- and middle-income countries (LMICs), between 20 and 25% of women encounter depression during pregnancy or soon after delivery. This condition impacts not only the mothers but also their offspring. Offspring of women suffering from postnatal depression (PND) exhibit suboptimal cognitive development and increased emotional and behavioural issues throughout their growth. This scenario becomes more pronounced in LMICs, where numerous adversities further jeopardise children's developmental progress. Despite antenatal services providing a pivotal platform to address women's mental health needs, PND treatment remains inaccessible in many LMICs. The World Health Organization advocates interpersonal psychotherapy (IPT) for treating depression. While research from high-income countries has established the efficacy of IPT and group-IPT (g-IPT) for PND, its effectiveness within the LMIC context and its potential benefits for child development remain uncharted. This study seeks to gauge the potency of g-IPT for women with PND in two LMICs. METHODS: This multi-site randomised controlled trial is a continuation of two preceding phases-conceptual mapping and a feasibility study executed in Lebanon and Kenya. Insights gleaned from these phases underpin this comprehensive RCT, which contrasts the efficacy and cost-effectiveness of high-quality standard care (HQ-SC) augmented with g-IPT against HQ-SC in isolation. The trial, characterised as an individually randomised superiority assessment, targets women with postnatal depression in Beirut, Lebanon, and Nairobi, Kenya. It aims to determine if culturally tailored g-IPT, administered within community settings in both countries, outperforms HQ-SC in influencing child developmental outcomes, maternal depression, and the quality of the mother-child bond. DISCUSSION: The SUMMIT trial, designed with pragmatism, possesses the magnitude to evaluate g-IPT within two LMIC frameworks. It seeks to enlighten policymakers, service commissioners, professionals, and users about g-IPT's potential to alleviate maternal PND and bolster child developmental outcomes in LMICs. Additionally, the trial will generate valuable data on the clinical and economic merits of high-quality standard care. TRIAL REGISTRATION: ISRCTN, ISRCTN15154316. Registered on 27 September 2023, https://doi.org/10.1186/ISRCTN15154316.

Coverage and determinants of infant postnatal care in Nigeria: A population-based cross-sectional study.

Importance: In 2019, Nigeria had the largest number of under-5 child deaths globally and many of these deaths occurred within the first week of life. The World Health Organization recommends infant postnatal care (PNC) attendance to support newborn survival; however, utilization of PNC is known to be low in many contexts. Objective: This study examined coverage and individual-level determinants of infant PNC attendance in Nigeria. Methods: Nigeria Demographic Health Survey (NDHS) 2018 data were used to evaluate infant PNC coverage and determinants. Infant PNC was defined as receipt of care within 2 days of birth. Children delivered up to 2 years before the 2018 NDHS were included. We examined predictors of infant PNC with modified Poisson regression models to estimate relative risks (RRs). Results: The national coverage of infant PNC was 37.3% (95% confidence interval [CI]: 35.8%-38.7%). Significant heterogeneity in PNC attendance existed at state and regional levels. Facility delivery was strongly associated with the uptake of PNC (RR: 6.07; 95% CI: 5.60-6.58). Greater maternal education, maternal employment, urban residence, female head of household, and greater wealth were also associated with an increased likelihood of PNC visits. Interpretation: The uptake of infant PNC is low and interventions are urgently needed to promote equity in access and increase demand for PNC in Nigeria.

[RECOMMENDATION FOR ITCH ASSESSMENT FROM THE ATOPIC ITCH CONSENSUS MEETING (AICOM)].

BACKGROUND: Itch is the most troublesome symptom of atopic dermatitis, and it is important to assess it appropriately for optimal treatment. We discussed issues regarding itch and the most appropriate methods of assessment at the Atopic Itch Consensus Meeting (AICOM), attended by physicians and researchers with expertise in itch treatment and research. METHODS: The AICOM participants prepared a draft consensus statement that addressed the most appropriate itch assessment methods for age groups <2 years, 2-6 years, 7-14 years, and ≥15 years. Consensus was defined as agreement by ≥80% of the participants. RESULTS: Votes were cast by 20 participants (8 dermatologists, 7 pediatricians, and 5 researchers), and a consensus on the best current methods of itch assessment was reached with 95% agreement. For infants and preschool children, because subjective evaluation is difficult, a checklist for itch assessment was developed for caregivers. CONCLUSION: For itch assessment, we recommend subjective evaluation by the patient using a rating scale. For infants and preschoolers, evaluation should be done by the caregiver using a checklist, combined with objective evaluation (of skin lesions, for example) by a physician. We anticipate that more objective itch assessment indices will be established in the future.

Optimizing ARA and DHA in infant formula: A systematic review of global trends, regional disparities, and considerations for precision nutrition.

In the context of precision nutrition, the addition of ARA and DHA in infant formula needs to consider more factors. This study conducted a comprehensive literature review, including 112 relevant Chinese and English articles, to summarize and analyze the global levels of ARA, DHA, and the ARA/DHA ratio in breast milk. The data were correlated with local aquatic products intake and children's IQ. The results indicated that the average level of DHA in breast milk across regions is lower than that of ARA. Variations in DHA content were identified as a primary factor influencing ARA/DHA ratio fluctuations. Breast milk ARA and DHA levels decrease with prolonged lactation periods but increase over the past 22 years. Correlation analysis revealed a significant positive relationship between aquatic products intake and breast milk DHA levels (r = 0.64, p < 0.05). Breast milk DHA levels also showed a significant positive correlation with children's IQ (r = 0.67, p < 0.01). Stable breast milk ARA content did not exhibit significant correlations with aquatic products intake or children's IQ (r = 0, p > 0.05). Among 22 infant formula products available in China, only 5 had ARA levels within the range of breast milk. Most formula products had higher ARA levels than DHA, resulting in ARA/DHA ratios generally exceeding 1. The temporal and spatial variability in breast milk ARA and DHA levels may lead to diverse health outcomes in infants. Therefore, the addition of ARA and DHA in infant formula should consider this variability, including the molecular forms and positional isomerism of the added ARA and DHA. Additionally, considering the impact of different cognitive development tests and infant's gene expression on formula assessment results, there is a need to establish a more comprehensive infant health assessment system to guide the addition of ARA and DHA in formula.

Associations between alcohol taxes and varied health outcomes among women of reproductive age and infants.

OBJECTIVE: No studies have examined whether alcohol taxes may be relevant for reducing harms related to pregnant people's drinking. METHOD: We examined how beverage-specific ad valorem, volume-based, and sales taxes are associated with outcomes across three data sets. Drinking outcomes came from women of reproductive age in the 1990-2020 US National Alcohol Surveys (N = 11 659 women $\le$ 44 years); treatment admissions data came from the 1992-2019 Treatment Episode Data Set: Admissions (N = 1331 state-years; 582 436 pregnant women admitted to treatment); and infant and maternal outcomes came from the 2005-19 Merative Marketscan® database (1 432 979 birthing person-infant dyads). Adjusted analyses for all data sets included year fixed effects, state-year unemployment and poverty, and accounted for clustering by state. RESULTS: Models yield no robust significant associations between taxes and drinking. Increased spirits ad valorem taxes were robustly associated with lower rates of treatment admissions [adjusted IRR = 0.95, 95% CI: 0.91, 0.99]. Increased wine and spirits volume-based taxes were both robustly associated with lower odds of infant morbidities [wine aOR = 0.98, 95% CI: 0.96, 0.99; spirits aOR = 0.99, 95% CI: 0.98, 1.00] and lower odds of severe maternal morbidities [wine aOR = 0.91, 95% CI: 0.86, 0.97; spirits aOR = 0.95, 95% CI: 0.92, 0.97]. Having an off-premise spirits sales tax was also robustly related to lower odds of severe maternal morbidities [aOR = 0.78, 95% CI: 0.64, 0.96]. CONCLUSIONS: Results show protective associations between increased wine and spirits volume-based and sales taxes with infant and maternal morbidities. Policies that index tax rates to inflation might yield more public health benefits, including for pregnant people and infants.

Caucasian and African American racial disparity in neonatal hospital mortality.

Objective: To examine disparity in hospital mortality among Caucasian (C) and African American (AA) neonates born at different gestational ages (GA). Methods: De-identified national inpatient data were obtained from the Healthcare Cost and Utilization Project (HCUP) from the Agency for Healthcare Research and Quality (AHRQ) for the years 2011-2018. We compared the odds ratio for mortality among C and AA infants by sex and GA category. Analyses were repeated after controlling for multiple maternal and neonatal confounding variables in a logistic regression model. Results: The study included 18,758,233 infants; 78.3% of them were C and 21.7% were AA. Compared to C population, AA population has a significantly higher mortality in term infants born at GA ≥ 36 weeks. The racial/ethnic disparity in preterm infants was inconsistent without any difference at 35-36 weeks in male and female infants. The overall aOR for mortality in AA in all male preterm infants ≤36 weeks was 1.44 (1.39-1.49), <0.01; and the overall aOR for mortality in AA in all preterm female infants ≤36 weeks was 1.38 (1.33-1.44). Conclusion: Racial/Ethnic disparity in hospital mortality exists with higher AA mortality in infants born with GA > 36 weeks and less AA mortality in infants born with GA 24-26 weeks.

"It doesn't matter if we're the most amazing professionals in the world " A qualitative study of professionals' perspectives on parent-child interaction assessment with deaf infants.

Introduction: Parent child interaction (PCI) is positively associated with deaf children's language development. However, there are no known, deaf-specific tools to observe how a parent interacts with their deaf child aged 0-3 years. Without a framework for professionals to use with families, it is unknown how professionals assess PCI, what they assess, why they assess, and how the assessment results relate to case management. Methods: Eighteen hearing and deaf professionals, who work with deaf and hard of hearing infants aged 0-3 years and their families, attended online focus groups. The aim of the study was to gain insight into the professional assessment of PCI. Data were analyzed using thematic analysis. Findings: Six themes were generated from the dataset. Professionals discussed how central parents were in the support offered to families in the home, the importance of knowing and understanding the individual family, and accounting for and supporting parental wellbeing. Descriptions on how to administer a best practice PCI assessment included which parent behaviors to assess and how to make adaptations for different populations. Professionals shared how the assessment and review process could be used to inform and upskill parents through video reflection and goal setting. Discussion: This study provides insight into the mechanisms and motivations for professionals assessing the interactive behaviors of parents who have deaf children aged 0-3. Professionals acknowledged that family life is multi-faceted, and that support is most meaningful to families when professionals worked with these differences and incorporated them into assessment, goal setting, and intervention plans.

Special economic zone and infant mortality: Evidence from China.

By exploiting the development of special economic zones (SEZs) in China as a quasi-natural experiment, this paper evaluates how such zones affect infant mortality. Difference-in-differences analysis reveals that SEZs significantly decrease the local infant mortality rate, and the impact is larger for male infants and infants with less-educated mothers. Further studies show that the SEZs, which acts as an economic growth shock, improve infant survival by increasing the local income. Furthermore, there is no supportive evidence that the SEZs significantly alter either women's fertility-associated behaviors or environmental pollution. These results highlight the previously ignored human capital-related consequences of place-based policies in China.

Inequity in US Racial/Ethnic Infant Health and Birth Outcomes: The Role of the Adult Sex Ratio as a Potential Indicator of Structural Anti-Black Racism.

BACKGROUND: Structural racism accounts for inequity in health outcomes in ways that are difficult to measure. To conduct more actionable research and measure the impact of intervention programs, there is a need to develop indicator measures of structural racism. One potential candidate is the Adult Sex Ratio (ASR), which was identified by Du Bois as an important indicator of social life functioning over 100 years ago and has remained significant up to the present day. This study investigated the utility of this measure. METHODS: We compared birth/infant health outcomes using the US 2000 Linked Birth/Infant Death Cohort Data Set matched with 2000 Census data on adult sex ratios in multilevel logistic regression models, stratified by the racial/ethnic category of the mothers. RESULTS: In an adjusted model, the odds of infant death was 21% higher among non-Hispanic Black (NHB) women living in counties in the lowest ASR tertile category when compared to their counterparts in counties in the highest ASR tertile. Similarly, the odds of giving birth to a preterm or a low birth weight infant were each 20% higher among NHB women living in counties in the lowest ASR tertile compared to their counterparts in counties in the highest ASR tertile. CONCLUSION: ASRs may serve as a useful indicator of anti-Black structural racism at the local level. More research is needed to determine the circumstances under which this factor may serve to improve assessment of structural racism and facilitate health equity research.

Agreement between Hammersmith Neonatal Neurological Examination (HNNE) and Test of Infant Motor Performance (TIMP) in neurodevelopmental assessment of preterm infants <32 weeks' gestation at term corrected age.

OBJECTIVES: To determine the agreement between HNNE and TIMP at TCA for preterm infants born <32+0 weeks' gestation, and to evaluate their correlation to PDMS-2 at 12-month corrected age (CA). METHODS: Infants born between November 2013 to June 2022 who had both HNNE and TIMP performed at TCA of 37+0-41+6 weeks gestation, and motor outcome assessed using the PDMS-2 at 12-month old were enrolled. The HNNE and 12-month PDMS-2 findings were categorized as optimal vs sub-optimal. TIMP was categorized as typical vs atypical. Cohen's kappa was used to determine the agreement between HNNE and TIMP. Sensitivity analysis and Receiver Operating Characteristic (ROC) curves were used to evaluate the predictive values of HNNE and TIMP on motor outcome at CA of 12-months. RESULTS: HNNE and TIMP done on 125 infants at TCA do not show reliable agreement. HNNE demonstrated slight and fair agreement with the 12-month Total Motor Quotient (TMQ) and Fine Motor Quotient (FMQ) of the PDMS-2 respectively. TIMP at TCA demonstrated fair agreement with all sub-domains of motor function on PDMS-2 at 12-months. In comparison with TIMP, HNNE at TCA is more sensitive at predicting suboptimal total, gross and fine motor outcomes at 12-month CA with sensitivity of 68.4 %, 51.9 %, and 83.3 % vs 44.4 %, 31.8 % and 53.3 % respectively. Atypical TIMP at TCA is more specific for suboptimal total, gross and fine motor outcomes at 12-month CA with specificity of 90.3 %, 89 % and 90.5 % respectively. Neurobehavioral assessments at TCA using HNNE and TIMP were predictive of suboptimal fine motor quotient at CA of 12-months with AUC of 0.760 (p = 0.011) and 0.718 (p = 0.032) respectively. The difference in AUC between the 2 instruments of 0.042 was not statistically significant (p = 0.741). CONCLUSIONS: While the HNNE and TIMP done at TCA did not demonstrate significant agreement, suboptimal HNNE and atypical TIMP at TCA were predictive of suboptimal FMQ on PDMS-2 at 12-month CA.

Microbiome function and neurodevelopment in Black infants: vitamin B12 emerges as a key factor.

The early life gut microbiome affects the developing brain, and therefore may serve as a target to support neurodevelopment of children living in stressful and under-resourced environments, such as Black youth living on the South Side of Chicago, for whom we observe racial disparities in health. Microbiome compositions/functions key to multiple neurodevelopmental facets have not been studied in Black children, a vulnerable population due to racial disparities in health; thus, a subsample of Black infants living in urban, low-income neighborhoods whose mothers participated in a prenatal nutrition study were recruited for testing associations between composition and function of the gut microbiome (16S rRNA gene sequencing, shotgun metagenomics, and targeted metabolomics of fecal samples) and neurodevelopment (developmental testing, maternal report of temperament, and observed stress regulation). Two microbiome community types, defined by high Lachnospiraceae or Enterobacteriaceae abundance, were discovered in this cohort from 16S rRNA gene sequencing analysis; the Enterobacteriaceae-dominant community type was significantly negatively associated with cognition and language scores, specifically in male children. Vitamin B12 biosynthesis emerged as a key microbiome function from shotgun metagenomics sequencing analysis, showing positive associations with all measured developmental skills (i.e., cognition, language, motor, surgency, effortful control, and observed stress regulation). Blautia spp. also were identified as substantial contributors of important microbiome functions, including vitamin B12 biosynthesis and related vitamin B12-dependent microbiome functions, anti-inflammatory microbial surface antigens, competitive mechanisms against pathobionts, and production of antioxidants. The results are promising with respect to the potential for exploring therapeutic candidates, such as vitamin B12 nutritional or Blautia spp. probiotic supplementation, to support the neurodevelopment of infants at risk for experiencing racial disparities in health.
