The association of area deprivation and state child health with respiratory outcomes of pediatric patients with cystic fibrosis in the United States

Associations between income level and health outcomes in people with cystic fibrosis in Turkey

BACKGROUND

Our study aimed to identify the social domains that pose the greatest barriers to managing and supporting pwCF, particularly in relation to income levels.

METHODS

To identify associations between income and health outcomes in pwCF in our center the shorter form of the survey "Your Current Life Situation" (YCLS) was used in face-to-face interviews. Participants were also asked to complete the validated Turkish versions of the 9-item Patient Health Questionnaire (PHQ-9) and the 7-item Generalized Anxiety Disorder scale (GAD-7) to assess depression and anxiety, respectively.

RESULTS

In total, 282 pwCF were included in this study. 51.1 % were female (n = 144), mean (±SD) age was 13.8 (±8.7) years and 75 % (n = 211) were <18 years old. The median (IQR) values of pwCF; FEV1pp (percent predictive) 83 % (41-97), BMI (body mass index) 17 kg/m2 (15∼20), BMI z-score -0.1 (-1∼0.3). Of the pwCF in the study 89 % (n = 251) had an income below the poverty threshold and 21 % (n = 60) of them had an income below the hunger threshold. The results of YCLS survey showed that the highest level of insecurity was in the social domain (68.5 %, n = 193); this was followed by health and clinical care (62.1 %, n = 173), financial (37.9 %, n = 106), and food insecurity (37.2 %, n = 103). All individuals experiencing housing insecurity stated that they had requested help from local organisations.

CONCLUSION

The study highlights the substantial socioeconomic challenges faced by pwCF, a significant majority live below the poverty threshold and experience high levels of social and health insecurity, underscoring the need for comprehensive support systems to address these issues.

Effects of Air Pollution on Respiratory Events and Pain Crises among Children with Sickle Cell Disease in New York City

Rationale: The disease burden of sickle cell disease (SCD) is highest among U.S. Black and Hispanic populations, which are often disproportionately represented in communities with poor air quality. There are limited data on the effects of air pollution exposure and social environmental factors on health outcomes in children with SCD. Objectives: The objectives of our study were to examine the associations between air pollution exposure and acute respiratory and vaso-occlusive pain crises (VOCs) and to further study the associations when stratifying by asthma status and neighborhood disadvantages. Methods: We conducted a retrospective study, collecting data on outpatient sick and emergency department visits, hospital admissions for respiratory events (i.e., respiratory tract infections, asthma exacerbation, acute chest syndrome), and hospitalizations for VOCs among children with SCD in a tertiary care center in New York City from 2015 to 2018. Modeled data from the New York City Community Air Survey data using home addresses' estimated street-level annual average exposure to air pollution (i.e., black carbon, particulate matter with an aerodynamic diameter ≤2.5 μm, and nitrogen dioxide). The area deprivation index (ADI) continuous national ranking percentile (1-100) was used, representing a composite index for neighborhood-level social disadvantage. We further dichotomized study participants at the upper tertile (high vs. low ADI). Multivariable Poisson regression in generalized estimating equation models were used to estimate relative risks (RRs) after adjusting for potential covariates. Results: A total of 114 children with SCD were included in this study and had between one and four annual repeated measures of annual average air pollutants over a total of 425 visits. Overall, there were no significant associations between air pollution levels and acute respiratory pain crises and VOCs among children with SCD and when stratified by asthma status. We found significant interactions between air pollution levels and the continuous ADI variable on respiratory outpatient and frequent respiratory outpatient/ED visits (P < 0.1). When stratified by high ADI, increased exposure to particulate matter with an aerodynamic diameter ≤2.5 μm was significantly associated with more frequent respiratory outpatient/emergency department visits among children residing in higher ADI neighborhoods (RR [95% confidence interval], 1.13 [1.01, 1.27]; P < 0.05), but not among those in lower ADI neighborhoods. Increased exposure to nitrogen dioxide was associated with more outpatient respiratory events for children in high ADI neighborhoods (RR [95% confidence interval], 2.74 [1.24, 6.08]; P < 0.05) compared with low ADI neighborhoods. Conclusions: Air pollution exposures increased respiratory complications among children with SCD living in deprived neighborhoods.

Race, Neighborhood Disadvantage, and Prehospital Law Enforcement Handcuffing in Children With Behavioral Health Emergencies

Importance

Minoritized youth and children in resource-limited neighborhoods rely on emergency medical services (EMS) for accessing care, including during behavioral health emergencies (BHEs). Law enforcement (LE) officers sometimes use forceful tactics in such settings. Assessing LE actions is needed to ensure safe and equitable care for vulnerable populations.

Objective

To examine whether race and ethnicity, neighborhood disadvantage, sex, and age are associated with LE handcuffing during pediatric BHEs.

Design, Setting, and Participants

This cross-sectional study analyzed LE handcuffing, demographic factors, and neighborhood disadvantage in Alameda County, California. The study population included children younger than 18 years who were evaluated by EMS for BHEs between January 1, 2012, and June 30, 2019. Data analysis was completed between January 1, 2022, and August 30, 2023.

Exposures

Primary exposures included race and ethnicity and Area Deprivation Index (ADI) rank as ADI I (1-3 [lowest]), ADI II (4-6 [moderate]), and ADI III (7-10 [highest]).

Main Outcome and Measure

The primary outcome was LE handcuffing during BHEs. The study calculated handcuffing proportions stratified by race and ethnicity, ADI, and sex.

Results

The final dataset consisted of 6759 pediatric BHE encounters with complete data. Among these, 3864 encounters (57.2%) were with females. The median age was 14.9 (IQR, 13.4-16.2) years. Overall, LE handcuffing occurred in 517 encounters (7.6%); Black children had higher odds than their White peers (adjusted odds ratio [AOR], 1.80; 95% CI, 1.39-2.33). Compared with low neighborhood disadvantage, moderate neighborhood disadvantage was independently associated with increased odds of handcuffing (ADI II: AOR, 1.51; 95% CI, 1.21-1.88), as was highest neighborhood disadvantage (ADI III: AOR, 1.54; 95% CI, 1.19-1.99). Male sex (AOR, 2.31; 95% CI, 1.91-2.79) and age (AOR per 1-year increase, 1.15; 95% CI, 1.10-1.21) were also associated with increased odds of handcuffing. In moderately disadvantaged neighborhoods, the odds were higher for Black children (AOR, 2.52; 95% CI, 1.65-3.86). When stratified by sex, the odds of handcuffing were significantly higher for Black females compared with White females (AOR, 2.59; 95% CI, 1.69-3.98).

Conclusions and Relevance

The findings of this cross-sectional study suggest that accessing EMS for BHEs may expose Black children and youth in disadvantaged neighborhoods to LE use of handcuffing. Emergency medical services should reconsider the role of LE officers in these settings.

Comparing two measures of neighborhood quality and internalizing and externalizing behaviors in the adolescent brain cognitive development study

PURPOSE

There is widespread recognition of the importance and complexity of measuring neighborhood contexts within research on child psychopathology. In this study, we assessed the cross-sectional associations between two measures of neighborhood quality and internalizing and externalizing behaviors in preadolescence.

METHODS

Drawing on baseline data from the Adolescent Brain Cognitive Development Study (n = 10,577 preadolescents), we examined two multi-component assessments of neighborhood quality in relation to children's internalizing and externalizing symptoms: the Area Deprivation Index (ADI), which measures socioeconomic adversity, and the Child Opportunity Index 2.0 (COI), which measures economic, educational, and environmental opportunity. Both measures were categorized into quintiles. We then used mixed-effects linear regression models to examine bivariate and adjusted associations.

RESULTS

The bivariate associations displayed strong inverse associations between the COI and ADI and externalizing symptoms, with a graded pattern of fewer externalizing behaviors with increasing neighborhood quality. Only the ADI was associated with externalizing behaviors in models adjusted for child and family characteristics. We did not observe a clear association between either measure of neighborhood quality and internalizing behaviors in bivariate or adjusted models.

CONCLUSIONS

Neighborhood quality, as measured by the COI and ADI, was associated with externalizing behaviors in preadolescent children. The association using the ADI persisted after adjustment for family-level characteristics, including financial strain. Our results indicate that different assessments of neighborhood quality display distinct associations with preadolescent behavioral health. Future research is needed to assess the association between neighborhood quality and behavior trajectories and to identify place-based intervention strategies.

Components of Residential Neighborhood Deprivation and Their Impact on the Likelihood of Live-Donor and Preemptive Kidney Transplantation

INTRODUCTION

Adults residing in deprived neighborhoods face various socioeconomic stressors, hindering their likelihood of receiving live-donor kidney transplantation (LDKT) and preemptive kidney transplantation (KT). We quantified the association between residential neighborhood deprivation index (NDI) and the likelihood of LDKT/preemptive KT, testing for a differential impact by race and ethnicity.

METHODS

We studied 403 937 adults (age ≥ 18) KT candidates (national transplant registry; 2006-2021). NDI and its 10 components were averaged at the ZIP-code level. Cause-specific hazards models were used to quantify the adjusted hazard ratio (aHR) of LDKT and preemptive KT across tertiles of NDI and its 10 components.

RESULTS

Candidates residing in high-deprivation neighborhoods were more likely to be female (40.1% vs. 36.2%) and Black (41.9% vs. 17.7%), and were less likely to receive both LDKT (aHR = 0.66, 95% confidence interval [CI]: 0.64-0.67) and preemptive KT (aHR = 0.60, 95% CI: 0.59-0.62) than those in low-deprivation neighborhoods. These associations differedby race and ethnicity (Black: aHRLDKT = 0.58, 95% CI: 0.55-0.62; aHRpreemptive KT = 0.68, 95% CI: 0.63-0.73; Pinteractions: LDKT < 0.001; Preemptive KT = 0.002). All deprivation components were associated with the likelihood of both LDKT and preemptive KT (except median home value): for example, higher median household income (LDKT: aHR = 1.08, 95% CI: 1.07-1.09; Preemptive KT: aHR = 1.10, 95% CI: 1.08-1.11) and educational attainments (≥high school [LDKT: aHR = 1.17, 95% CI: 1.15-1.18; Preemptive KT: aHR = 1.23, 95% CI: 1.21-1.25]).

CONCLUSION

Residence in socioeconomically deprived neighborhoods is associated with a lower likelihood of LDKT and preemptive KT, differentially impacting minority candidates. Identifying and understanding which neighborhood-level socioeconomic status contributes to these racial disparities can be instrumental in tailoring interventions to achieve health equity in LDKT and preemptive KT.

Neighborhood Racial and Ethnic Segregation and the Risk of Dementia in Older Adults Living with Kidney Failure

Key Points

Background

Dementia disproportionately affects older minoritized adults with kidney failure. To better understand the mechanism of this disparity, we studied the role of racial and ethnic segregation (segregation hereafter), i.e., a form of structural racism recently identified as a mechanism in numerous other health disparities.

Methods

We identified 901,065 older adults (aged ≥55 years) with kidney failure from 2003 to 2019 using the United States Renal Data System. We quantified dementia risk across tertiles of residential neighborhood segregation score using cause-specific hazard models, adjusting for individual- and neighborhood-level factors. We included an interaction term to quantify the differential effect of segregation on dementia diagnosis by race and ethnicity.

Results

We identified 79,851 older adults with kidney failure diagnosed with dementia between 2003 and 2019 (median follow-up: 2.2 years). Compared with those in low-segregation neighborhoods, older adults with kidney failure in high-segregation neighborhoods had a 1.63-fold (95% confidence interval [CI], 1.60 to 1.66) higher risk of dementia diagnosis, an association that differed by race and ethnicity (Asian: adjusted hazard ratio [aHR] = 1.26, 95% CI, 1.15 to 1.38; Black: aHR = 1.66, 95% CI, 1.61 to 1.71; Hispanic: aHR = 2.05, 95% CI, 1.93 to 2.18; White: aHR = 1.59, 95% CI, 1.55 to 1.64; P interaction < 0.001). Notably, older Asian (aHR = 1.76; 95% CI, 1.64 to 1.89), Black (aHR = 2.65; 95% CI, 2.54 to 2.77), Hispanic (aHR = 2.15; 95% CI, 2.04 to 2.26), and White (aHR = 2.20; 95% CI, 2.09 to 2.31) adults with kidney failure residing in minority-predominant high-segregation neighborhoods had a higher risk of dementia diagnosis compared with older White adults with kidney failure in White-predominant high-segregation neighborhoods. Moreover, older adults with kidney failure receiving care at dialysis facilities located in high-segregation neighborhoods also experienced a higher risk of dementia diagnosis (aHR = 1.53; 95% CI, 1.50 to 1.56); this association differed by race and ethnicity (P interaction < 0.001).

Conclusions

Residing in or receiving care at dialysis facilities located in high-segregation neighborhoods was associated with a higher risk of dementia diagnosis among older individuals with kidney failure, particularly minoritized individuals.

Social determinants of respiratory health from birth: still of concern in the 21st century?

Respiratory symptoms are ubiquitous in children and, even though they may be the harbinger of poor long-term outcomes, are often trivialised. Adverse exposures pre-conception, antenatally and in early childhood have lifetime impacts on respiratory health. For the most part, lung function tracks from the pre-school years at least into late middle age, and airflow obstruction is associated not merely with poor respiratory outcomes but also early all-cause morbidity and mortality. Much would be preventable if social determinants of adverse outcomes were to be addressed. This review presents the perspectives of paediatricians from many different contexts, both high and low income, including Europe, the Americas, Australasia, India, Africa and China. It should be noted that there are islands of poverty within even the highest income settings and, conversely, opulent areas in even the most deprived countries. The heaviest burden of any adverse effects falls on those of the lowest socioeconomic status. Themes include passive exposure to tobacco smoke and indoor and outdoor pollution, across the entire developmental course, and lack of access even to simple affordable medications, let alone the new biologicals. Commonly, disease outcomes are worse in resource-poor areas. Both within and between countries there are avoidable gross disparities in outcomes. Climate change is also bearing down hardest on the poorest children. This review highlights the need for vigorous advocacy for children to improve lifelong health. It also highlights that there are ongoing culturally sensitive interventions to address social determinants of disease which are already benefiting children.

Neighborhood Disadvantage and Clinical Outcome Following Concussion in Adolescents

Whether social determinants of health are associated with clinical outcome following concussion among adolescents is not well established. The present study examined whether neighborhood-level determinants are associated with clinical recovery time following concussion in adolescents. Participants included adolescent student athletes (n = 130; mean age = 16.6, standard deviation = 1.2; 60.8% boys, 39.2% girls) who attended one of nine selected high schools in Maine, USA. The Area of Deprivation Index (ADI), an indicator of neighborhood disadvantage was used to group high schools as either high or low in neighborhood disadvantage. Athletic trainers entered injury and recovery dates into an online surveillance application between September 2014 and January 2020. Chi-squared analyses and Kaplan-Meier survival analyses were used to compare the groups on two clinical outcomes: days to return to school and days to return to sports. Results of chi-squared tests did not reveal between-group differences in return to school at 21 or 28 days. However, groups differed in the percentage of adolescents who had returned to sports by 21 days (greater neighborhood disadvantage, 62.5%, lesser neighborhood disadvantage 82.0%, χ2 = 4.96, p = 0.03, odds ratio [OR] = 2.73, 95% confidence interval [CI], 1.11-6.74) and 28 days (greater neighborhood disadvantage, 78.6%, lesser neighborhood disadvantage 94.0%, χ2 = 5.18, p = 0.02, OR = 4.27, 95% CI, 1.13-16.16) following concussion. A larger proportion of adolescents attending schools located in areas of greater neighborhood disadvantage took more than 21 and 28 days to return to sports. These results indicate an association between a multi-faceted proxy indicator of neighborhood disadvantage and clinical outcome following concussion. Further research is needed to better characterize factors underlying group differences in time to return to sports and the interactions between neighborhood disadvantage and other correlates of clinical recovery following concussion.

Breath of fresh insight: unraveling the evolution of our understanding of cystic fibrosis pulmonary exacerbations

PURPOSE OF REVIEW

Pulmonary exacerbations are critical events with significant negative impacts in persons with cystic fibrosis, but their diagnosis and management are highly variable. Highly effective modulator therapies have greatly improved health and reduced exacerbation events, but have also reshaped how they present. This review discusses the complexities of the diagnosis and management of pulmonary exacerbations as well as the emerging work and evidence in this area.

RECENT FINDINGS

The shifting epidemiology and our understanding of risk factors for pulmonary exacerbations are discussed. As symptoms may be more subtle in the modulator context, novel technologies including studies of remote monitoring are presented. The continued relevance of pulmonary exacerbations, the heterogeneity in their management, as well as current and forthcoming clinical trials to optimize treatment approaches are detailed.

SUMMARY

In spite of the dramatic reductions in pulmonary exacerbations, airway infections persist, a proportion of persons with cystic fibrosis either on or off modulator therapies continue to experience exacerbation events, and long-term data is lacking. Innovative approaches and studies will be crucial to enable standardized and generalizable strategies to improve outcomes in persons with cystic fibrosis.

Aiming to Improve Equity in Pulmonary Health: Cystic Fibrosis

This review summarizes the evidence of health disparities in cystic fibrosis (CF), an autosomal recessive genetic disorder with substantial variation in disease progression and outcomes. We review disparities by race, ethnicity, socioeconomic status, geographic location, gender identity, or sexual orientation documented in the literature. We outline the mechanisms that generate and perpetuate such disparities across levels and domains of influence and assess the implications of this evidence. We then recommend strategies for improving equity in CF outcomes, drawing on recommendations for the general population and considering approaches specific to people living with CF.

Poverty and relapse risk in children with acute lymphoblastic leukemia: a Children's Oncology Group study AALL03N1 report

The association between individual-level poverty and relapse in children receiving maintenance treatment for acute lymphoblastic leukemia (ALL) remains unclear. In a secondary analysis of COG-AALL03N1, we used data from US Census Bureau to categorize patients living below year-specific federal poverty thresholds, calculated using self-reported annual household income and size of household. Participants with federal poverty thresholds above 120% of their yearly household income were categorized as living in extreme poverty. Hazard of relapse was estimated using multivariable proportional subdistributional hazards regression for patients living in extreme poverty while receiving ALL maintenance therapy after adjusting for relevant predictors. Among 592 patients in this analysis, 12.3% of the patients were living in extreme poverty. After a median follow-up of 7.9 years, the cumulative incidence of relapse at 3 years from study enrollment among those living in extreme poverty was significantly higher (14.3%) than those not living in extreme poverty (7.6%). Multivariable analysis demonstrated that children living in extreme poverty had a 1.95-fold greater hazard of relapse than those not living in extreme poverty; this association was mitigated after the inclusion of race/ethnicity in the model, likely because of collinearity between race/ethnicity and poverty. A greater proportion of children living in extreme poverty were nonadherent to mercaptopurine (57.1% vs 40.9%); however, poor adherence did not completely explain the association between poverty and relapse risk. Future studies need to understand the mechanisms underlying the association between extreme poverty and relapse risk. This trial was registered at www.clinicaltrials.gov as #NCT00268528.

The implications of socioeconomic factors on salivary bioscience methodological variables in a large pediatric multi-site study

Introduction

Salivary bioscience has found increased utilization within pediatric research, given the non-invasive nature of self-collecting saliva for measuring biological markers. With this growth in pediatric utility, more understanding is needed of how social-contextual factors, such as socioeconomic factors or status (SES), influence salivary bioscience in large multi-site studies. Socioeconomic factors have been shown to influence non-salivary analyte levels across childhood and adolescent development. However, less is understood about relationships between these socioeconomic factors and salivary collection methodological variables (e.g., time of saliva collection from waking, time of day of saliva collection, physical activity prior to saliva collection, and caffeine intake prior to saliva collection). Variability in salivary methodological variables between participants may impact the levels of analytes measured in a salivary sample, thus serving as a potential mechanism for non-random systematic biases in analytes.

Methods

Our objective is to examine relationships between socioeconomic factors and salivary bioscience methodological variables within the Adolescent Brain Cognitive Development Study© cohort of children aged 9-10 years old (n = 10,567 participants with saliva samples).

Results

We observed significant associations between household socioeconomic factors (poverty status, education) and salivary collection methodological variables (time since waking, time of day of sampling, physical activity, and caffeine intake). Moreover, lower levels of household poverty and education were significantly associated with more sources of potential bias in salivary collection methodological variables (e.g., longer times since waking, collections later in the day, higher odds of caffeine consumption, and lower odds of physical activity). Consistent associations were not observed with neighborhood socioeconomic factors and salivary methodological variables.

Discussion

Previous literature demonstrates associations between collection methodological variables and measurements of salivary analyte levels, particularly with analytes that are more sensitive to circadian rhythms, pH levels, or rigorous physical activity. Our novel findings suggest that unintended distortions in measured salivary analyte values, potentially resulting from the non-random systematic biases in salivary methodology, need to be intentionally incorporated into analyses and interpretation of results. This is particularly salient for future studies interested in examining underlying mechanisms of childhood socioeconomic health inequities in future analyses.

Built environment factors predictive of early rapid lung function decline in cystic fibrosis

BACKGROUND

The extent to which environmental exposures and community characteristics of the built environment collectively predict rapid lung function decline, during adolescence and early adulthood in cystic fibrosis (CF), has not been examined.

OBJECTIVE

To identify built environment characteristics predictive of rapid CF lung function decline.

METHODS

We performed a retrospective, single-center, longitudinal cohort study (n = 173 individuals with CF aged 6-20 years, 2012-2017). We used a stochastic model to predict lung function, measured as forced expiratory volume in 1 s (FEV1 ) of % predicted. Traditional demographic/clinical characteristics were evaluated as predictors. Built environmental predictors included exposure to elemental carbon attributable to traffic sources (ECAT), neighborhood material deprivation (poverty, education, housing, and healthcare access), greenspace near the home, and residential drivetime to the CF center.

MEASUREMENTS AND MAIN RESULTS

The final model, which included ECAT, material deprivation index, and greenspace, alongside traditional demographic/clinical predictors, significantly improved fit and prediction, compared with only demographic/clinical predictors (Likelihood Ratio Test statistic: 26.78, p < 0.0001; the difference in Akaike Information Criterion: 15). An increase of 0.1 μg/m3 of ECAT was associated with 0.104% predicted/yr (95% confidence interval: 0.024, 0.183) more rapid decline. Although not statistically significant, material deprivation was similarly associated (0.1-unit increase corresponded to additional decline of 0.103% predicted/year [-0.113, 0.319]). High-risk regional areas of rapid decline and age-related heterogeneity were identified from prediction mapping.

CONCLUSION

Traffic-related air pollution exposure is an important predictor of rapid pulmonary decline that, coupled with community-level material deprivation and routinely collected demographic/clinical characteristics, enhance CF prognostication and enable personalized environmental health interventions.

Race- and Neighborhood-Related Disparities Spanning the COVID-19 Pandemic: Trajectories of Combined Glycemic Control and BMI in Youth With Diabetes

OBJECTIVE

To use combined glycemic (HbA1c) and BMI z-score (BMIZ) trajectories spanning the coronavirus disease 2019 (COVID-19) pandemic to identify high-risk subgroups of adolescents with diabetes.

RESEARCH DESIGN AND METHODS

Retrospective cohort of adolescents 10-19 years old with type 1 and type 2 diabetes with one or more visits at a large pediatric hospital from January 2018 through February 2020 (prepandemic) and April 2020 through August 2021 (pandemic). Group-based trajectory models were used to identify latent classes of combined BMIZ and HbA1c trajectories. Multinomial logistic regression was used to evaluate predictors of class membership, including Area Deprivation Index (ADI) (socioeconomic status proxy).

RESULTS

The cohort included 1,322 youth with type 1 diabetes (93% White and 7% Black) and 59 with type 2 diabetes (53% Black and 47% White). For type 1 diabetes, six trajectory classes emerged. Black youth were more likely to be in the class with worsening glycemic control and concurrent BMIZ decrease at pandemic onset (relative risk ratio [RRR] vs. White: 3.0 [95% CI 1.3-6.8]) or in the class with progressively worsening glycemic control and obesity (RRR 3.0 [95% CI 1.3-6.8]), while those from the most deprived neighborhoods (RRR ADI tertile 3 vs. 1: 1.9 [95% CI 1.2-2.9]) were more likely to be in the class with stable obesity and glycemic control. For type 2 diabetes, three distinct trajectories emerged, two of which experienced worsening glycemic control with concurrent BMIZ decline at pandemic onset.

CONCLUSIONS

Race and neighborhood deprivation were independently associated with distinct glycemic and BMIZ trajectory classes in youth with diabetes, highlighting persistent and widening disparities associated with the COVID-19 pandemic.

Healthcare Use in the Year Following Bronchiolitis Hospitalization

OBJECTIVES

Healthcare utilization after bronchiolitis hospitalization is incompletely understood. We aimed to characterize readmissions and outpatient visits within 1 year after hospital discharge.

METHODS

Retrospective multicenter observational cohort study of children under 24-months old admitted with bronchiolitis between January 1, 2010 and December 12, 2019 to the Pediatric Health Information Systems database. A single-center nested subset using linked electronic health records allowed analysis of outpatient visits.

RESULTS

There were 308 306 admissions for bronchiolitis among 271 115 patients across 47 hospitals between 2010-2019. The percent of patients readmitted within 30 days after discharge was 6.0% (16 167 of 271 115), and 17.8% (48 332 of 271 115) of patients were readmitted within 1 year. 22.9% (16 919 of 74 001) of patients admitted to an ICU and 26.8% (7865 of 29 378) of patients undergoing mechanical ventilation were readmitted within 1 year. There were 1438 patients with outpatient healthcare data available. There were a median (interquartile range) of 9 (6-13) outpatient visits per patient within 1 year after discharge. Outpatient healthcare use increased for 4 months following bronchiolitis hospitalization compared with previously reported age-matched controls. Higher income, white race, commercial insurance, complex chronic conditions, ICU admission, and mechanical ventilation were associated with higher outpatient utilization. Higher quartiles of outpatient use were associated with readmission for bronchiolitis and all-cause readmissions.

CONCLUSIONS

Readmissions in the year after bronchiolitis hospitalization are common, and outpatient healthcare use is increased for 4 months following discharge. Prospective study is needed to track long-term outcomes of infants with bronchiolitis.

Area deprivation and respiratory morbidities in children with bronchopulmonary dysplasia

INTRODUCTION

Infants and children diagnosed with bronchopulmonary dysplasia (BPD) have a higher likelihood of recurrent hospitalizations and asthma-like symptoms. Socio-environmental factors that influence the frequency and severity of pulmonary symptoms in these children during the preschool age are poorly understood. In this study, we used the Area Deprivation Index (ADI) to evaluate the relationship between the socio-environmental exposures in children with BPD and respiratory outcomes during the first few years of life.

METHODS

A registry of subjects recruited from outpatient BPD clinics at Johns Hopkins University (n = 909) and the Children's Hospital of Philadelphia (n = 125) between January 2008 and October 2021 was used. Subjects were separated into tertiles by ADI scores aggregated to ZIP codes. Caregiver questionnaires were used to assess the frequency of respiratory morbidities and acute care usage for respiratory symptoms.

RESULTS

The mean gestational age of subjects was 26.8 ± 2.6 weeks with a mean birthweight of 909 ± 404 g. The highest tertile (most deprived) of ADI was significantly associated with emergency department visits (aOR 1.72; p = 0.009), hospital readmissions (aOR 1.66; p = 0.030), and activity limitations (aOR 1.55; p = 0.048) compared to the lowest tertile. No association was seen with steroid, antibiotic or rescue medication use, trouble breathing, or nighttime symptoms.

CONCLUSION

In this study, children with BPD who lived in areas of higher deprivation were more likely to be rehospitalized and have ED visits for respiratory reasons. Identifying socio-environmental factors that contribute to adverse pulmonary outcomes in children with BPD may provide opportunities for earlier interventions to improve long-term pulmonary outcomes.

Socioeconomic determinants of respiratory health in patients with cystic fibrosis: implications for treatment strategies

INTRODUCTION

Great variation exists in the progression and outcomes of cystic fibrosis (CF) lung disease, due to both genetic and environmental influences. Social determinants mediate environmental exposures and treatment success; people with CF from socioeconomically disadvantaged backgrounds have worse health and die younger than those in more advantaged positions.

AREAS COVERED

This paper reviews the literature on the mechanisms that are responsible for generating and sustaining disparities in CF health, and the ways by which social determinants translate into health advantages or disadvantages in people with CF. The authors make recommendations for addressing social risk factors in CF clinical practice.

EXPERT OPINION

Socioeconomic factors are not dichotomous and their impact is felt at every step of the social ladder. CF care programs need to adopt a systematic protocol to screen for health-related social risk factors, and then connect patients to available resources to meet individual needs. Considerations such as daycare, schooling options, living and working conditions, and opportunities for physical exercise and recreation as well as promotion of self-efficacy are often overlooked. In addition, advocacy for changes in public policies on health insurance, environmental regulations, social welfare, and education would all help address the root causes of CF health inequities.

Experiences and Perspectives of Individuals with Cystic Fibrosis and Their Families Related to Food Insecurity

Food insecurity (FI) rates among people with cystic fibrosis (CF) are significantly higher than in the general US population. This study explored the experiences and perceptions of adults and parents of children with CF surrounding FI. We recruited parents of children with CF ages 0–18 years and adults with CF ages 18 years and older from a large, accredited U.S. CF care center and the Cystic Fibrosis Foundation Community Voice to participate in a qualitative study using semi-structured telephone interviews to explore experiences and preferences related to food insecurity. Two coders independently reviewed each transcript to apply the codebook and identify any emerging codes using an ongoing, iterative process to identify central themes. We interviewed 20 participants (six adults with CF and 14 parents of children with CF) and identified five major themes: (1) FI in CF is influenced by a variety of factors, ranging from nutritional demands to competing financial barriers; (2) FI impacts CF health outcomes; (3) Open patient-provider communication around FI is vital; (4) FI screening and discussions should be normalized in CF care; (5) Comprehensive FI resources are vital. FI is an important topic that should routinely be addressed with the CF care team to destigmatize and encourage individuals to be more forthcoming about their FI status. Results from this study will inform future larger investigations on the impact of FI on CF health and aid in the design and planning of targeted interventions and advocacy efforts.

Care for Chiari malformation type I: the role of socioeconomic disadvantage and race

OBJECTIVE

There is little research on the effect of social determinants of health on Chiari malformation type I (CM-I). The authors analyzed data on all children evaluated for CM-I at a single institution to assess how socioeconomic factors and race affect the surgical treatment of this population.

METHODS

Medical records of patients treated for CM-I at the authors' institution between 1992 and 2017 were reviewed. Area Deprivation Index (ADI) and Rural-Urban Commuting Area (RUCA) codes for each patient were used to measure neighborhood disadvantage. Non-Hispanic White patients were compared to non-White patients and Hispanic patients of any race (grouped together as non-White in this study) in terms of insurance status, ADI, and RUCA. Patients with initially benign CM-I, defined as not having undergone surgery within 9 months of their initial visit, were then stratified by having delayed symptom presentation or not, and compared on these same measures.

RESULTS

The sample included 665 patients with CM-I: 82% non-Hispanic White and 18% non-White. The non-White patients were more likely to reside in disadvantaged (OR 3.4, p < 0.001) and urban (OR 4.66, p < 0.001) neighborhoods and to have public health insurance (OR 3.11, p < 0.001). More than one-quarter (29%) of patients underwent surgery. The non-White and non-Hispanic White patients had similar surgery rates (29.5% vs 28.9%, p = 0.895) at similar ages (8.8 vs 9.7 years, p = 0.406). There were no differences by race/ethnicity for symptoms at presentation. Surgical and nonsurgical patients had similar ADI scores (3.9 vs 4.2, p = 0.194), RUCA scores (2.1 vs 2.3, p = 0.252), and private health insurance rates (73.6% vs 74.2%, p = 0.878). A total of 153 patients underwent surgery within 9 months of their initial visit. The remaining 512 were deemed to have benign CM-I. Of these, 40 (7.8%) underwent decompression surgery for delayed symptom presentation. Patients with delayed symptom presentation were from less disadvantaged (ADI 3.2 vs 4.2; p = 0.025) and less rural (RUCA 1.8 vs 2.3; p = 0.023) areas than those who never underwent surgery.

CONCLUSIONS

Although non-White patients were more likely to be socioeconomically disadvantaged, race and socioeconomic disadvantage were not associated with undergoing surgical treatment. However, among patients with benign CM-I, those undergoing decompression for delayed symptom presentation resided in more affluent and urban areas.

Geospatial Analysis of Food Deserts and Their Impact on Health Outcomes in Children with Cystic Fibrosis

Food insecurity (FI) is defined as "the limited or uncertain access to adequate food." One root cause of FI is living in a food desert. FI rates among people with cystic fibrosis (CF) are higher than the general United States (US) population. There is limited data on the association between food deserts and CF health outcomes. We conducted a retrospective review of people with CF under 18 years of age at a single pediatric CF center from January to December 2019 using demographic information and CF health parameters. Using a Geographic Information System, we conducted a spatial overlay analysis at the census tract level using the 2015 Food Access Research Atlas to assess the association between food deserts and CF health outcomes. We used multivariate logistic regression analysis and adjusted for clinical covariates and demographic covariates, using the Child Opportunity Index (COI) to calculate odds ratios (OR) with confidence intervals (CI) for each health outcome. People with CF living in food deserts and the surrounding regions had lower body mass index/weight-for-length (OR 3.18, 95% CI: 1.01, 9.40, p ≤ 0.05 (food desert); OR 4.41, 95% CI: 1.60, 12.14, p ≤ 0.05 (600 ft buffer zone); OR 2.83, 95% CI: 1.18, 6.76, p ≤ 0.05 (1200 ft buffer zone)). Food deserts and their surrounding regions impact pediatric CF outcomes independent of COI. Providers should routinely screen for FI and proximity to food deserts. Interventions are essential to increase access to healthy and affordable food.
