White Infants Research Articles

Diversity and representation in infant research: Barriers and bridges toward a globalized science of infant development.

Psychological researchers have become increasingly concerned with generalized accounts of human behavior based on narrow participant representation. This concern is particularly germane to infant research as findings from infant studies are often invoked to theorize broadly about the origins of human behavior. In this article, we examined participant diversity and representation in research published on infant development in four journals over the past decade. Sociodemographic data were coded for all articles reporting infant data published in Child Development, Developmental Science, Developmental Psychology, and Infancy between 2011 and 2022. Analyses of 1682 empirical articles, sampling approximately 1 million participants, revealed consistent under-reporting of sociodemographic information. For studies that reported sociodemographic characteristics, there was an unwavering skew toward White infants from North America/Western Europe. To address a lack of diversity in infant studies and its scientific impact, a set of principles and practices are proposed to advance toward a more globally representative science.

Neighborhood Deprivation and Association With Neonatal Intensive Care Unit Mortality and Morbidity for Extremely Premature Infants

Socioeconomic status affects pregnancy and neurodevelopment, but its association with hospital outcomes among premature infants is unknown. The Area Deprivation Index (ADI) is a validated measure of neighborhood disadvantage that uses US Census Bureau data on income, educational level, employment, and housing quality. To determine whether ADI is associated with neonatal intensive care unit (NICU) mortality and morbidity in extremely premature infants. This retrospective cohort study was performed at 4 level IV NICUs in the US Northeast, Mid-Atlantic, Midwest, and South regions. Non-Hispanic White and Black infants with gestational age of less than 29 weeks and born between January 1, 2012, and December 31, 2020, were included in the analysis. Addresses were converted to census blocks, identified by Federal Information Processing Series codes, to link residences to national ADI percentiles. ADI, race, birth weight, sex, and outborn status. In the primary outcome, the association between ADI and NICU mortality was analyzed using bayesian logistic regression adjusted for race, birth weight, outborn status, and sex. Risk factors were considered significant if the 95% credible intervals excluded zero. In the secondary outcome, the association between ADI and NICU morbidities, including late-onset sepsis, necrotizing enterocolitis (NEC), and severe intraventricular hemorrhage (IVH), were also analyzed. A total of 2765 infants with a mean (SD) gestational age of 25.6 (1.7) weeks and mean (SD) birth weight of 805 (241) g were included in the analysis. Of these, 1391 (50.3%) were boys, 1325 (47.9%) reported Black maternal race, 498 (18.0%) died before NICU discharge, 692 (25.0%) developed sepsis or NEC, and 353 (12.8%) had severe IVH. In univariate analysis, higher median ADI was found among Black compared with White infants (77 [IQR, 45-93] vs 57 [IQR, 32-77]; P < .001), those who died before NICU discharge vs survived (71 [IQR, 45-89] vs 64 [IQR, 36-86]), those with late-onset sepsis or NEC vs those without (68 [IQR, 41-88] vs 64 [IQR, 35-86]), and those with severe IVH vs those without (69 [IQR, 44-90] vs 64 [IQR, 36-86]). In a multivariable bayesian logistic regression model, lower birth weight, higher ADI, and male sex were risk factors for mortality (95% credible intervals excluded zero), while Black race and outborn status were not. The ADI was also identified as a risk factor for sepsis or NEC and severe IVH. The findings of this cohort study of extremely preterm infants admitted to 4 NICUs in different US geographic regions suggest that ADI was a risk factor for mortality and morbidity after adjusting for multiple covariates.

Epidemiology of Salmonellosis Among Infants in the United States: 1968-2015.

Describe characteristics of gastroenteritis, bacteremia, and meningitis caused by nontyphoidal Salmonella among US infants. We analyze national surveillance data during 1968-2015 and active, sentinel surveillance data during 1996-2015 for culture-confirmed Salmonella infections by syndrome, year, serotype, age, and race. During 1968-2015, 190 627 culture-confirmed Salmonella infections among infants were reported, including 165 236 (86.7%) cases of gastroenteritis, 6767 (3.5%) bacteremia, 371 (0.2%) meningitis, and 18 253 (9.7%) with other or unknown specimen sources. Incidence increased during the late 1970s-1980s, declined during the 1990s-early 2000s, and has gradually increased since the mid-2000s. Infants' median age was 4 months for gastroenteritis and bacteremia and 2 months for meningitis. The most frequently reported serotypes were Typhimurium (35 468; 22%) for gastroenteritis and Heidelberg for bacteremia (1954; 29%) and meningitis (65; 18%). During 1996-2015 in sentinel site surveillance, median annual incidence of gastroenteritis was 120, bacteremia 6.2, and meningitis 0.25 per 100 000 infants. Boys had a higher incidence of each syndrome than girls in both surveillance systems, but most differences were not statistically significant. Overall, hospitalization and fatality rates were 26% and 0.1% for gastroenteritis, 70% and 1.6% for bacteremia, and 96% and 4% for meningitis. During 2004-2015, invasive salmonellosis incidence was higher for Black (incident rate ratio, 2.7; 95% confidence interval, 2.6-2.8) and Asian (incident rate ratio, 1.8; 95% confidence interval, 1.7-1.8) than white infants. Salmonellosis causes substantial infant morbidity and mortality; serotype heidelberg caused the most invasive infections. Infants with meningitis were younger than those with bacteremia or gastroenteritis. Research into risk factors for infection and invasive illness could inform prevention efforts.

Association of Biomarker-Based Artificial Intelligence With Risk of Racial Bias in Retinal Images

Although race is a social construct, it is associated with variations in skin and retinal pigmentation. Image-based medical artificial intelligence (AI) algorithms that use images of these organs have the potential to learn features associated with self-reported race (SRR), which increases the risk of racially biased performance in diagnostic tasks; understanding whether this information can be removed, without affecting the performance of AI algorithms, is critical in reducing the risk of racial bias in medical AI. To evaluate whether converting color fundus photographs to retinal vessel maps (RVMs) of infants screened for retinopathy of prematurity (ROP) removes the risk for racial bias. The retinal fundus images (RFIs) of neonates with parent-reported Black or White race were collected for this study. A u-net, a convolutional neural network (CNN) that provides precise segmentation for biomedical images, was used to segment the major arteries and veins in RFIs into grayscale RVMs, which were subsequently thresholded, binarized, and/or skeletonized. CNNs were trained with patients' SRR labels on color RFIs, raw RVMs, and thresholded, binarized, or skeletonized RVMs. Study data were analyzed from July 1 to September 28, 2021. Area under the precision-recall curve (AUC-PR) and area under the receiver operating characteristic curve (AUROC) at both the image and eye level for classification of SRR. A total of 4095 RFIs were collected from 245 neonates with parent-reported Black (94 [38.4%]; mean [SD] age, 27.2 [2.3] weeks; 55 majority sex [58.5%]) or White (151 [61.6%]; mean [SD] age, 27.6 [2.3] weeks, 80 majority sex [53.0%]) race. CNNs inferred SRR from RFIs nearly perfectly (image-level AUC-PR, 0.999; 95% CI, 0.999-1.000; infant-level AUC-PR, 1.000; 95% CI, 0.999-1.000). Raw RVMs were nearly as informative as color RFIs (image-level AUC-PR, 0.938; 95% CI, 0.926-0.950; infant-level AUC-PR, 0.995; 95% CI, 0.992-0.998). Ultimately, CNNs were able to learn whether RFIs or RVMs were from Black or White infants regardless of whether images contained color, vessel segmentation brightness differences were nullified, or vessel segmentation widths were uniform. Results of this diagnostic study suggest that it can be very challenging to remove information relevant to SRR from fundus photographs. As a result, AI algorithms trained on fundus photographs have the potential for biased performance in practice, even if based on biomarkers rather than raw images. Regardless of the methodology used for training AI, evaluating performance in relevant subpopulations is critical.

Trend Toward Older Maternal Age Contributed To Growing Racial Inequity In Very-Low-Birthweight Infants In The US.

In 2016 the Centers for Disease Control and Prevention reported that for the first time, US women in their thirties were bearing more children than those in their twenties. Analyzing US vital statistics data from the period 1989-2019, we simulated the effect that the distributional shift to older maternal ages at first birth had on health inequity between Black and White infants. Net of maternal socioeconomic indicators, this shift increased the relative odds that White women gave birth to very-low-birthweight (VLBW) infants by 10percent, versus 19percent for Black women, largely accounting for the rise in VLBW and the increase in racial inequity seen in the years analyzed. Reductions in infant mortality over the period were dampened by the maternal age shift, especially among Black babies, exacerbating Black-White inequity. Policy implications for promoting reproductive justice include universal tertiary care access, increasing the supply and distribution of maternity care providers, addressing the holistic needs of mothers throughout pregnancy and postpartum, and expanding family support policies. Conceptually, we recommend centering the realities of pregnancy and parenting from the perspective of the populations at highest risk-centering on the margins-and taking into account their implications for maternal weathering (accelerated deterioration due to disparate impacts of structural racism).

Perspectives of Infant Mortality from African American Community Members.

Infant mortality (IM) is often used to determine overall population health and well-being. Health disparities exist with African American (AA) infants having higher rates of IM than White infants. The purpose of this study was to examine the knowledge, attitudes, and perceptions of members in an AA community regarding IM, which can be used to develop interventions. A qualitative descriptive design guided this study. A county in the state of Indiana was the setting from which the researchers enrolled participants in this study. The participants consisted of 16 AA community members who were recruited from a local agency and who had completed an educational program on IM. Through semistructured phone interviews, participants described their understanding of IM. The data analysis of the transcribed interviews was performed via content analysis to yield overall themes from the data. The analysis identified three themes describing AA Community members' perspectives on IM: (1) Shying Away from the Topic of Infant Mortality; (2) Receiving Misinformation from Family Members; and (3) Considering Infant Mortality as Unpreventable. The findings of this study suggest that participants avoided the topic of IM, often received misinformation from family members, and believed infant death could not be prevented. Health care providers should have an open and culturally competent discussion about issues of IM, engage family members, and support community-based initiatives and education for members in AA communities.

Race, hypoxaemia and oxidative stress in prematurely-born infants

BackgroundDisparities in neonatal respiratory outcomes in prematurely-born infants might be partially explained by racial differences and the relationship of hypoxia and oxidative stress. AimsTo determine if Black, preterm infants were exposed more frequently to hypoxaemia compared to White infants and had a higher level of oxidative damage. Study designSingle-centre retrospective cohort study at King's College Hospital, London, UK between 2018 and 2021. SubjectsInfants born before 32 completed weeks of gestational age. Outcome measuresThe median arterial oxygen saturation (SaO2) over the first seven days was measured. The maximum carboxyhaemoglobin (COHb) level for the first three days was also recorded as an index of oxidative stress. ResultsTwo thousand and sixty blood gases from 87 infants (38 Black) with a median (IQR) gestational age of 26.4 (24.6–28.3) weeks were analysed. The median (IQR) SaO2 was not significantly different in Black [96.1 (95.2–96.8) %] compared to White infants [96.7 (95.6–97.7) %, p = 0.24]. The median (IQR) COHb was not significantly different in Black infants [1.9 (1.7–2.4) %] compared to White infants [1.9 (1.7–2.3) %, p = 0.77]. The highest COHb was significantly related to the median SaO2 in all infants (r = −0.51, p < 0.001) and separately in Black (r = −0.50, p = 0.002) and White (r = −0.56, p < 0.001) infants. ConclusionsPreterm, Black infants were not exposed more frequently to hypoxaemia compared to White infants. Lower saturation levels were associated with higher maximum carboxyhaemoglobin levels indicating a higher risk of oxidative stress, irrespective of racial background.

Association of State-Level Tax Policy and Infant Mortality in the United States, 1996-2019

Infant mortality in the United States is highest among peer nations; it is also inequitable, with the highest rates among Black infants. The association between tax policy and infant mortality is not well understood. To examine the association between state-level tax policy and state-level infant mortality in the US. This state-level, population-based cross-sectional study investigated the association between tax policy and infant mortality in the US from 1996 through 2019. All US infant births and deaths were included, with data obtained from the National Center for Health Statistics. Data were analyzed from November 28, 2021, to July 9, 2022. State-level tax policy was operationalized as tax revenue per capita and tax progressivity. The Suits index was used to measure tax progressivity, with higher progressivity indicating increased tax rates for wealthier individuals. The association between tax policy and infant mortality rates was analyzed using a multivariable, negative binomial, generalized estimating equations model. Since 6 years of tax progressivity data were available (1995, 2002, 2009, 2012, 2014, and 2018), 300 state-years were included. Adjusted incidence rate ratios (aIRRs) were calculated controlling for year, state-level demographic variables, federal transfer revenue, and other revenue. Secondary analyses were conducted for racial and ethnic subgroups. There were 148 336 infant deaths in the US from 1996 through 2019, including 27 861 Hispanic infants, 1882 non-Hispanic American Indian or Alaska Native infants, 5792 non-Hispanic Asian or Pacific Islander infants, 41 560 non-Hispanic Black infants, and 68 666 non-Hispanic White infants. The overall infant mortality rate was 6.29 deaths per 1000 live births. Each $1000 increase in tax revenue per capita was associated with a 2.6% decrease in the infant mortality rate (aIRR, 0.97; 95% CI, 0.95-0.99). An increase of 0.10 in the Suits index (ie, increased tax progressivity) was associated with a 4.6% decrease in the infant mortality rate (aIRR, 0.95; 95% CI, 0.91-0.99). Increased tax progressivity was associated with decreased non-Hispanic White infant mortality (aIRR, 0.95; 95% CI, 0.91-0.99), and increased tax revenue was associated with increased non-Hispanic Black infant mortality (aIRR, 1.04; 95% CI, 1.01-1.08). In this cross-sectional study, an increase in tax revenue and the Suits index of tax progressivity were both associated with decreased infant mortality. These associations varied by race and ethnicity. Tax policy is an important, modifiable social determinant of health that may influence state-level infant mortality.

Reclassification of the Etiology of Infant Mortality With Whole-Genome Sequencing

Understanding the causes of infant mortality shapes public health, surveillance, and research investments. However, the association of single-locus (mendelian) genetic diseases with infant mortality is poorly understood. To determine the association of genetic diseases with infant mortality. This cohort study was conducted at a large pediatric hospital system in San Diego County (California) and included 546 infants (112 infant deaths [20.5%] and 434 infants [79.5%] with acute illness who survived; age, 0 to 1 year) who underwent diagnostic whole-genome sequencing (WGS) between January 2015 and December 2020. Data analysis was conducted between 2015 and 2022. Infants underwent WGS either premortem or postmortem with semiautomated phenotyping and diagnostic interpretation. Proportion of infant deaths associated with single-locus genetic diseases. Among 112 infant deaths (54 girls [48.2%]; 8 [7.1%] African American or Black, 1 [0.9%] American Indian or Alaska Native, 8 [7.1%] Asian, 48 [42.9%] Hispanic, 1 [0.9%] Native Hawaiian or Pacific Islander, and 34 [30.4%] White infants) in San Diego County between 2015 and 2020, single-locus genetic diseases were the most common identifiable cause of infant mortality, with 47 genetic diseases identified in 46 infants (41%). Thirty-nine (83%) of these diseases had been previously reported to be associated with childhood mortality. Twenty-eight death certificates (62%) for 45 of the 46 infants did not mention a genetic etiology. Treatments that can improve outcomes were available for 14 (30%) of the genetic diseases. In 5 of 7 infants in whom genetic diseases were identified postmortem, death might have been avoided had rapid, diagnostic WGS been performed at time of symptom onset or regional intensive care unit admission. In this cohort study of 112 infant deaths, the association of genetic diseases with infant mortality was higher than previously recognized. Strategies to increase neonatal diagnosis of genetic diseases and immediately implement treatment may decrease infant mortality. Additional study is required to explore the generalizability of these findings and measure reduction in infant mortality.

Sociodemographic factors associated with tracheostomy and mortality in bronchopulmonary dysplasia.

We sought to investigate how race, ethnicity, and socioeconomic status relate to tracheostomy insertion and post-tracheostomy mortality among infants with bronchopulmonary dysplasia (BPD). The Vizient Clinical Database/Resource Manager was queried to identify infants born ≤32 weeks with BPDadmitted to US hospitals from January 2012 to December 2020. Markers of socioeconomic status were linked to patient records from the Agency for Healthcare Research and Quality's Social Determinants of Health Database. Regression models were used to assess trends in annual tracheostomy insertion rate and odds of tracheostomy insertion and post-tracheostomy mortality, adjusting for sociodemographic and clinical factors. There were 40,021 ex-premature infants included in the study, 1614 (4.0%) of whom received a tracheostomy. Tracheostomy insertion increased from 2012 to 2017 (3.1%-4.1%), but decreased from 2018 to 2020 (3.3%-1.6%). Non-Hispanic Black infants demonstrated a 25% higher odds (aOR 1.25, 1.09-1.43) and Hispanic infants demonstrated a 20% lower odds (aOR 0.80, 0.65-0.96) of tracheostomy insertion compared withnon-Hispanic White infants. Patients receiving public insurance had increased odds of tracheostomy insertion (aOR 1.15, 1.03-1.30), but there was no relation between other metrics of socioeconomic status and tracheostomy insertion within our cohort. In-hospital mortality among the tracheostomy-dependent was 14.1% and was not associated with sociodemographic factors. Disparities in tracheostomy insertion are not accounted for by differences in socioeconomic status or the presence of additional neonatal morbidities. Post-tracheostomy mortality does not demonstrate the same relationships. Further investigation is needed to explore the source and potential mitigators of the identified disparities.

A new perspective on the role of physical salience in visual search: Graded effect of salience on infants' attention.

We tested 6- and 8-month-old White and non-White infants (N = 53 total, 28 girls) from Northern California in a visual search task to determine whether a unique item in an otherwise homogeneous display (a singleton) attracts attention because it is a unique singleton and "pops out" in a categorical manner, or whether attention instead varies in a graded manner on the basis of quantitative differences in physical salience. Infants viewed arrays of four or six items; one item was a singleton and the other items were identical distractors (e.g., a single cookie and three identical toy cars). At both ages, infants looked to the singletons first more often, were faster to look at singletons, and looked longer at singletons. However, when a computational model was used to quantify the relative salience of the singleton in each display-which varied widely among the different singleton-distractor combinations-we found a strong, graded effect of physical salience on attention and no evidence that singleton status per se influenced attention. In addition, consistent with other research on attention in infancy, the effect of salience was stronger for 6-month-old infants than for 8-month-old infants. Taken together, these results show that attention-getting and attention-holding in infancy vary continuously with quantitative variations in physical salience rather than depending in a categorical manner on whether an item is unique.

Racial Differences in Retinopathy of Prematurity

ABSTRACT Purpose To delineate racial differences in the incidence and time course of ROP in a large cohort of premature infants. Methods The secondary analysis of data from the two Postnatal Growth and ROP Studies (G-ROP-1 and G-ROP-2) that were collected in 41 hospitals in North America from 2006 to 2017. According to self-reported maternal race, premature infants were classified into 3 groups: White (N = 5580), Black (N = 3252), and Asian (N = 353). Incidence, severity, and time course of ROP; plus disease; and postnatal weight gain rate were compared among racial groups. Results Black infants had significantly smaller BW (mean 1035 vs. 1131 vs.1144 grams, P < .001) and lower GA (28.2 vs. 28.6, vs. 29.1 weeks, P < .001) than White and Asian infants. However, Black infants had lower incidences of severe ROP (11.1% vs. 12.4% vs. 11.9%), ROP (42.1% vs. 43.2% vs. 30.6%), and plus disease (3.6% vs. 6.3%, vs. 5.9%) than White and Asian infants (BW and GA adjusted risk ratio for Black vs. White 0.69 for severe ROP, 0.83 for ROP, 0.44 for plus disease, all P < .0001). Mean daily-weight-gain on days of life 11–20 and 21–30 were similar across groups (P > .05), but lower in Black and Asian infants on days 31–40 (P < .001). There were no differences in the timing of severe ROP and ROP across racial groups. Conclusions Despite relatively lower GA, BW, and daily-weight-gain, Black preterm infants had lower incidences of ROP and plus disease than White preterm infants. The mechanisms for these differences require further investigation.

Webcam Use in the Neonatal Intensive Care Unit during the First Year of the SARS-CoV-2 Pandemic.

The aim of this study was to evaluate patterns of webcam use in families of patients admitted to a neonatal intensive care unit (NICU) during the first year of the pandemic and characterize the families who used the technology. Retrospective chart review of the medical records and logins of our live webcam system was conducted for 2020. From January 1, 2020, to December 31, 2020, 843 infants were admitted to the NICU, with lengths of stay range of 1 to 169 days. More than half (n = 496, 58.8%) of all families of infants admitted to the NICU used the webcam system during the period of study. The number of webcam users did not change between the pre-coronavirus disease 2019 (COVID-19) and during COVID-19 time periods, or during versus after NICU visitor restrictions. Among webcam users, the median (interquartile range) number of logins per day was 2.9 (2.9) and ranged from 0 to 44. There were significant differences among races, site of admission, and diagnosis groups. Families of White infants had more frequent use compared with families of Black infants. Families of infants admitted for surgical reasons had more frequent use compared with those admitted for medical reasons. Among 284 of the 496 (57.3%) webcam users, we documented logins from 37 states in the United States and from 10 different countries. Webcam use is common in the NICU. There was no increase in webcam use within the first year of the COVID-19 pandemic in the NICU. More studies are needed to evaluate how this technology is used in the NICU and its impact on patients and families. · Webcam use in the NICU is common.. · Visitor restrictions did not increase webcam use.. · We observed racial differences in webcam use..

Demographic disparities in tracheal intubation success rates during infant out-of-hospital cardiac arrest

ObjectivesTracheal intubation is a skill performed by qualified emergency medical services (EMS) providers during out-of-hospital cardiac arrest (OHCA) in adult and pediatric patients. Unsuccessful intubation can negatively impact a patient's likelihood of survival. Thus, intubation success rates are an important quality improvement benchmark. Given other demographic disparities that have been reported in adults and children, we hypothesize there might be disparities in intubation success across infant race/ethnicity and/or sex. MethodsWe examined a national-level registry of EMS activations in the United States (NEMSIS). Inclusion criteria were OHCA calls involving infant patients (under 1 years of age) between January 2017 and May 2022 where EMS attempted tracheal intubation, documented whether the procedure was successful, and documented information about the patient's demographics (eg. race/ethnicity and sex). Intubation success rates across patient sex and racial/ethnic categories with more than one-hundred cardiac arrests with intubation attempts were compared. ResultsA total of 3663 infant cardiac arrests where tracheal intubation was attempted met inclusion criteria. White infants were associated with significantly higher rates of intubation success (62.2%) when compared with Black or African American infants (58.1%) and Hispanic/Latino infants (56.2%) (p < .01). Female infants were associated with slightly higher rates of intubation success than male infants, but this difference was not significant (p > .2). ConclusionSignificant demographic disparities in endotracheal intubation success rates exist among infants who experience OHCA. Future studies should continue to examine these disparities with the goal of identifying why these differences occur and concrete mechanisms for eliminating such disparities.

The Relationship Between Diet, Gut Microbiota, and Serum Metabolome of South Asian Infants at 1 Year

BackgroundDiet is known to affect the gut microbiota and the serum metabolome in adults, but this has not been fully explored in infants. Infancy is an important developmental period that may influence a person’s long-term health. Infant development can be affected by diet, which also interacts with the developing gut microbiota. ObjectivesThis study aimed to explore the associations between diet, the gut microbiota, and the serum metabolome of 1-y-old infants with the overarching goal of identifying serum biomarkers of diet and/or the gut microbiota. MethodsWe derived dietary patterns of 1-y-old infants (n = 182) participating in the Canadian South Asian Birth Cohort (START) study. We compared gut microbiota α-diversity and β-diversity and taxa relative abundance from 16S rRNA gene profiles with dietary patterns (PERMANOVA, Envfit) and investigated diet–serum metabolite associations using a multivariate analysis (partial least squares–discriminant analysis) and univariate analysis (t test). We explored the effect of nondietary factors on diet–serum metabolite relationships by incorporating diet, the gut microbiota, and maternal, perinatal, and infant characteristics in a multivariable forward stepwise regression. We replicated this analysis in White European infants, from the CHILD Cohort Study (n = 81). ResultsA dietary pattern characterized by formula consumption and negatively associated with breastfeeding most strongly predicted variation in the gut microbiota (R2 = 0.109) and serum metabolome (R2 = 0.547). Breastfed participants showed higher abundance of microbes from the genera Bifidobacterium (3.29 log2-fold) and Lactobacillus (7.93 log2-fold) and higher median concentrations of the metabolites S-methylcysteine (1.38 μM) and tryptophan betaine (0.43 μM) than nonbreastfed participants. Formula consuming infants showed higher median concentrations of branched-chain/aromatic amino acids (average 48.3 μM) than non–formula-consuming infants. ConclusionsFormula consumption and breastfeeding most strongly predicted the serum metabolites of 1-y-old infants, even when the gut microbiota, solid food consumption, and other covariates were considered.

Association of Severe Bronchiolitis during Infancy with Childhood Asthma Development: An Analysis of the ECHO Consortium.

Objective: Many studies have shown that severe (hospitalized) bronchiolitis during infancy is a risk factor for developing childhood asthma. However, the population subgroups at the highest risk remain unclear. Using large nationwide pediatric cohort data, namely the NIH Environmental influences on Child Health Outcomes (ECHO) Program, we aimed to quantify the longitudinal relationship of bronchiolitis hospitalization during infancy with asthma in a generalizable dataset and to examine potential heterogeneity in terms of major demographics and clinical factors. Methods: We analyzed data from infants (age <12 months) enrolled in one of the 53 prospective cohort studies in the ECHO Program during 2001−2021. The exposure was bronchiolitis hospitalization during infancy. The outcome was a diagnosis of asthma by a physician by age 12 years. We examined their longitudinal association and determined the potential effect modifications of major demographic factors. Results: The analytic cohort consisted of 11,762 infants, 10% of whom had bronchiolitis hospitalization. Overall, 15% subsequently developed asthma. In the Cox proportional hazards model adjusting for 10 patient-level factors, compared with the no-bronchiolitis hospitalization group, the bronchiolitis hospitalization group had a significantly higher rate of asthma (14% vs. 24%, HR = 2.77, 95%CI = 2.24−3.43, p < 0.001). There was significant heterogeneity by race and ethnicity (Pinteraction = 0.02). The magnitude of the association was greater in non-Hispanic White (HR = 3.77, 95%CI = 2.74−5.18, p < 0.001) and non-Hispanic Black (HR = 2.39, 95%CI = 1.60−3.56; p < 0.001) infants, compared with Hispanic infants (HR = 1.51, 95%CI = 0.77−2.95, p = 0.23). Conclusions: According to the nationwide cohort data, infants hospitalized with bronchiolitis are at a higher risk for asthma, with quantitative heterogeneity in different racial and ethnic groups.

Racial and incident discrepancies in news media reporting of sudden unexpected infant death (SUID)

BackgroundRegardless of injury prevention and outreach efforts, there continue to be low rates of adherence with the American Academy of Pediatrics (AAP) safe sleep recommendations. Media is an important tool for parental education and may influence risk perception and caregiver choices. Due to media reports potentially serving as an opportunity for shaping social norms, caregiver education and injury prevention, an evaluation was undertaken to evaluate Georgia local news reporting of sudden unexpected infant death (SUID) as compared to drownings, homicides, and firearm injuries. Our objective was to evaluate incident and racial discrepancies in Georgia news media reporting of SUID as compared to other pediatric injury deaths.ResultsDespite its high incidence, SUID was far less commonly mentioned in the news media, with only 1.9% (10/525) mentioned as compared to 8.1% of drownings (17/211), 11.4% (74/649) of MVC’s, 14.7% (59/402) of homicides between ages 1–18, 20% (11/55) of fire-related deaths and 25% (15/59) of homicides under age one (infant homicides). Across SUID and homicide, deaths of White infants were reported in the news media at 2.5 times the rate of Black infants.ConclusionDespite SUID being a leading cause of infant death, it is infrequently mentioned in the news media. When mentioned, the news media are more likely to highlight the deaths of White infants as compared to Black infants, though the incidence rate of SUID is higher in Black infants as compared to White.

Racial differentials in American Indian- White American Postneonatal Mortality in the United States: evidence from cohort linked birth/infant death records

PurposePostneonatal mortality (PNM), which differs from infant and perinatal mortality, has been observed in the past 25 years with respect to the health outcomes of children. While infant and perinatal mortality have been well-evaluated regarding racial differentials, there are no substantial data on PNM in this perspective. The purpose of this study was to assess whether or not social determinants of health adversely affect racial/ethnic PNM differentials in the USA.Design/methodology/approachA cross-sectional, nonexperimental epidemiologic study design was used to assess race as an exposure function of PNM using Cohort Linked Birth/Infant Death Data (2013). The outcome variable assessed PNM, while the main independent variables were race, social demographic variables (i.e. sex and age) and social determinants of health (i.e. marital status and maternal education). The chi-square statistic was used to assess the independence of variables by race, while the logistic regression model was used to assess the odds of PNM by race and other confounding variables.FindingsDuring 2013, there were 4,451 children with PNM experience. The cumulative incidence of PNM was 23.6% (n = 2,795) among white infants, 24.3% (n = 1,298) among Black/African-Americans (AA) and 39.5% (n = 88) were American-Indian infants (AI), while 21.3% (n = 270) were multiracial, χ2 (3) = 35.7, p < 0.001. Racial differentials in PNM were observed. Relative to White infants, PNM was two times as likely among AI, odds ratio (OR) 2.11 (95% confidence interval [CI] 1.61, 2.78). After controlling for the confounding variables, the burden of PNM persisted among AI, although slightly marginalized, adjusted odds ratio (aOR) 1.70, (99% CI 1.10, 2.65).Originality/valueIn a representative sample of US children, there were racial disparities in PNM infants who are AI compared to their white counterparts, illustrating excess mortality. These findings suggest the need to allocate social and health resources in transforming health equity in this direction.

Responding to joint attention as a developmental catalyst: Longitudinal associations with language and social responsiveness.

Joint attention (JA), infants' ability to engage in triadic attention with another person and a separate object or event, emerges in infancy. Responding to joint attention (RJA) develops earlier than initiating joint attention (IJA) and may benefit from a reconceptualization from a competence to a skill that varies in performance. Investigating associations between RJA performance and important skills of toddlerhood such as language, social responsiveness, and executive function (EF) in typically developing samples can better elucidate how RJA may serve as a developmental precursor to later dimensional skills, with implications for both typical and atypical development. Here, 210 (82% White) infants completed the Dimensional Joint Attention Assessment (DJAA), a naturalistic play-based assessment of RJA, at 8-15months. At 16-38months social responsiveness, verbal ability, and EF were assessed. Multilevel models showed that DJAA scores were associated with later verbal abilities and parent-reported social responsiveness. Exploratory analyses showed trend-level associations between RJA and EF. Results establish the content validity of the DJAA as a measure of RJA, and longitudinal associations with later verbal ability and social responsiveness. Future work should examine EF emergence and consolidation, and RJA and later EF associations.
