OBJECTIVES: Adverse childhood experiences (ACEs) have been linked to adulthood chronic diseases, but there is little research examining the mechanisms underlying this association. We tested pathways from ACEs to adult disease mediated via risk factors of depression, smoking, and body mass index. METHOD: Prospective data from adults 18 to 74 years old from the Hispanic Community Health Study/Study of Latinos and Sociocultural Ancillary Study were used. Retrospectively reported ACEs and hypothesized mediators were measured at Visit 1 (2008-2011). Outcomes of disease prevalence were assessed at Visit 2, approximately 6 years later. The analytic sample includes 5,230 Hispanic/Latino participants with ACE data. Statistical mediation was examined using structural equation modeling on cardiometabolic and pulmonary disease prevalence and reported probit regression coefficients with 95% confidence intervals (CIs). RESULTS: We found a significant association between ACEs and the prevalence of asthma/chronic obstructive pulmonary disorder (standardized ß = .07, 95% CI [0.02, 0.12]). In the mediational model, the direct association was nonsignificant (ß = .02, 95% CI [-0.04, 0.07]) but was mediated by depressive symptoms (ß = .03, 95% CI [0.02, 0.04]). There were no associations between ACEs and the prevalence of diabetes and self-reported coronary heart disease or cerebrovascular disease. However, a small indirect effect was identified via depressive symptoms and coronary heart disease (ß = .02, 95% CI [0.01, 0.03]). CONCLUSION: In this diverse Hispanic/Latino sample, depressive symptoms were found to be a pathway linking ACEs to self-reported cardiopulmonary diseases, although the effects were of small magnitude. Future work should replicate pathways, confirm the magnitude of effects, and examine cultural moderators that may dampen expected associations.

OBJECTIVE: There are persistent disparities in pediatric asthma morbidity in the U.S. We linked claims data with information on neighborhood-level risk factors to explore drivers of asthma disparities among Medicaid-enrolled children in New York City subsidized housing. METHODS: We constructed a cohort of Medicaid-enrolled children living in public or other subsidized housing, based on residential address, in NYC between 2016 and 2019 (n = 108,969). We examined claims-derived asthma prevalence across age and racial and ethnic groups, integrating census tract-level information and using the Bayesian Improved Surname Geocoding (BISG) algorithm to address high rates of missing data in self-reported race and ethnicity. We used inverse probability weighting (IPW) to explore the extent to which disparities persisted when exposure to asthma risk factors - related to the built environment, neighborhood poverty, and air quality - were balanced across groups. This analysis was conducted in 2022-2023. RESULTS: Claims-derived asthma prevalence was highest among children <7 years at baseline and among non-Hispanic Black and Hispanic children. For example, among children aged 3-6 years at baseline, claims-derived prevalence was 17.3% and 18.1% among non-Hispanic Black and Hispanic children, respectively, compared to 9.3% and 9.0% among non-Hispanic White and non-Hispanic Asian American/Pacific Islander children. Using IPW to balance exposure to asthma risk factors across racial and ethnic groups attenuated, but did not eliminate, disparities in asthma prevalence. CONCLUSIONS: We found high asthma burden among children living in subsidized housing. Modifiable place-based characteristics may be important contributors to pediatric asthma disparities.

BACKGROUND: Emerging adults (aged 18-29) are less likely to receive the COVID-19 vaccine than any other adult age group. Black Americans are less likely than non-Hispanic white Americans to be fully vaccinated against COVID-19. This study explored factors which affect vaccine intention and attitudes in Black American emerging adults with asthma. METHODS: Participants were recruited from an NHLBI-funded clinical trial to improve asthma control. Fifty-nine Black American emerging adults completed a Qualtrics survey that assessed asthma control, intention to vaccinate, and factors which may affect the decision to vaccinate. Twenty-five participants also completed a semi-structured interview via Zoom. Bivariate correlations and descriptive statistics, including Chi Square analyses, were run using SPSS. Interview thematic analyses were conducted via QDA Miner. RESULTS: Of the 59 Black American emerging adults with asthma who completed surveys, 32.2% responded that they were highly unlikely to receive the COVID-19 vaccine, while 50.8% responded that they were highly likely to receive it. Increased asthma control was significantly correlated with a higher likelihood to discuss the COVID-19 vaccine with their healthcare provider (ρ = 0.339, α = 0.011). Concerns about immediate (ρ= -0.261, α = 0.050) and long-term (ρ= -0.280, α = 0.035) side effects were inversely correlated with intention to vaccinate. Only 17% of the participants who were unemployed stated that they were highly likely to receive the vaccines compared to 65% of the participants who were employed; however, interview participants who were unemployed stated not needing the vaccine because they were protecting themselves by social distancing. When deciding whether to receive the vaccine, safety, efficacy, and immediate side effects were the top three factors for 91%, 54%, and 49% of the participants, respectively. Beliefs about the vaccines' safety and efficacy, information gathering, personal factors, and societal factors emerged as important themes from the interviews. CONCLUSION: Only half of the surveyed Black American emerging adults with asthma were highly likely to receive the COVID-19 vaccine. Safety and efficacy were important for the majority of the participants, regardless of vaccine intention. Greater asthma control, but not access to asthma-related healthcare, was correlated with intention to discuss the vaccine with their healthcare provider.

The Global Lung Initiative (GLI) race-neutral equations are considered to be race agnostic, using inverse probability weight, and have lower limits of normality (LLN) different from the GLI mixed equations. In this observational study, we analyzed the impact of using GLI equations to interpret spirometry of 1,169 patients with chronic respiratory diseases, including asthma, chronic obstructive pulmonary disease (COPD), COPD suspects, small airway obstruction, posttubercular lung disease, and preserved ratio with impaired spirometry (PRISm) (46% females, average age 46 years). Predicted normal and the LLN using GLI equations were significantly higher than those using Indian equations. The GLI race-neutral equations changed the category in 35.17% of males and 42.64% of females compared to Indian equations. The GLI mixed equations categorized a greater percentage of patients to have a mixed ventilatory pattern compared to the GLI race-neutral equations. There was a significant change in the grading of the severity of COPD using Global Initiative for Chronic Obstructive Lung Disease (GOLD) stages based on the percentage of predicted values of FEV1. Although GLI race-neutral equations have greater concordance with Indian equations than GLI Mixed equations, these substantially overdiagnose abnormal ventilatory patterns on spirometry in adult Indians in western India with chronic respiratory disease. A substantial number of patients with normal or obstructive patterns on spirometry are recategorized to have mixed or restrictive patterns. The use of GLI race-neutral equations increases the severity of airflow limitation in COPD patients. GLI race-neutral predictions for FEV1 result in substantially fewer patients demonstrating postbronchodilator responsiveness (PBDR).

BACKGROUND AND OBJECTIVES: Asthma is a common, potentially serious childhood chronic condition that disproportionately afflicts Black children. Hospitalizations and emergency department (ED) visits for asthma can often be prevented. Nearly half of children with asthma are covered by Medicaid, which should facilitate access to care to manage and treat symptoms. We provide new evidence on racial disparities in asthma hospitalizations and ED visits among Medicaid-enrolled children. METHODS: We used comprehensive Medicaid claims data from the Transformed Medicaid Statistical Information System. Our study population included 279 985 Medicaid-enrolled children with diagnosed asthma. We identified asthma hospitalizations and ED visits occurring in 2019. We estimated differences in the odds of asthma hospitalizations and ED visits for non-Hispanic Black versus non-Hispanic white children, adjusting for sex, age, Medicaid eligibility group, Medicaid plan type, state, and rurality. RESULTS: In 2019, among Black children with asthma, 1.2% had an asthma hospitalization and 8.0% had an asthma ED visit compared with 0.5% and 3.4% of white children with a hospitalization and ED visit, respectively. After adjusting for other characteristics, the rates for Black children were more than twice the rates for white children (hospitalization adjusted odds ratio 2.45, 95% confidence interval 2.23-2.69; ED adjusted odds ratio 2.42; 95% confidence interval 2.33-2.51). CONCLUSIONS: There are stark racial disparities in asthma hospitalizations and ED visits among Medicaid-enrolled children with asthma. To diminish these disparities, it will be important to implement solutions that address poor quality care, discriminatory treatment in health care settings, and the structural factors that disproportionately expose Black children to asthma triggers and access barriers.

BACKGROUND: The Pediatric Asthma Severity Score (PASS) is one of the most-used clinical scoring systems for assessing the severity of asthma exacerbations in children. The aim of the present study was to validate a Spanish version of the PASS in a population of Hispanic children with asthma exacerbations living in urban Bogota, Colombia. METHODS: In a prospective cohort and a validation study, parents/caregivers of children between 2 and 18 years old attended in the emergency department (ED) with asthma exacerbations who were admitted to the inpatient unit were invited to participate in the study. During the hospitalization period, we gathered the necessary data for assessing the criterion validity (comparing its score with the Pediatric Respiratory Assessment Measure [PRAM]), construct validity, interrater reliability, responsiveness, and internal consistency of the Col-PASS, the Colombian version of the PASS. RESULTS: At baseline, the scores of the Col-PASS correlated positively with the scores of the PRAM score (ρ = 0.588, p < .001). The baseline Col-PASS scores in patients who required admission to a more complex service were significantly higher than those in patients who presented clinical improvement (1.0 (0.0-2.0) vs. 0.0 (0.0-0.0), p < .001). The interrater reliability was found to be κ = 0.897, 95% CI 0.699-1.000, p < .001. Cronbach's α was .701 for the questionnaire as a whole. CONCLUSION: The Col-PASS has excellent construct validity, adequate criterion validity, interrater reliability, responsiveness; and acceptable internal consistency when used in children between 2 and 18 years old with asthma exacerbations.

Importance: Mortality rates in US youth have increased in recent years. An understanding of the role of racial and ethnic disparities in these increases is lacking. Objective: To compare all-cause and cause-specific mortality trends and rates among youth with Hispanic ethnicity and non-Hispanic American Indian or Alaska Native, Asian or Pacific Islander, Black, and White race. Design, Setting, and Participants: This cross-sectional study conducted temporal analysis (1999-2020) and comparison of aggregate mortality rates (2016-2020) for youth aged 1 to 19 years using US Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research database. Data were analyzed from June 30, 2023, to January 17, 2024. Main Outcomes and Measures: Pooled, all-cause, and cause-specific mortality rates per 100â¯000 youth (hereinafter, per 100â¯000) for leading underlying causes of death were compared. Injuries were classified by mechanism and intent. Results: Between 1999 and 2020, there were 491â¯680 deaths among US youth, including 8894 (1.8%) American Indian or Alaska Native, 14â¯507 (3.0%) Asian or Pacific Islander, 110â¯154 (22.4%) Black, 89â¯251 (18.2%) Hispanic, and 267â¯452 (54.4%) White youth. Between 2016 and 2020, pooled all-cause mortality rates were 48.79 per 100â¯000 (95% CI, 46.58-51.00) in American Indian or Alaska Native youth, 15.25 per 100â¯000 (95% CI, 14.75-15.76) in Asian or Pacific Islander youth, 42.33 per 100â¯000 (95% CI, 41.81-42.86) in Black youth, 21.48 per 100â¯000 (95% CI, 21.19-21.77) in Hispanic youth, and 24.07 per 100â¯000 (95% CI, 23.86-24.28) in White youth. All-cause mortality ratios compared with White youth were 2.03 (95% CI, 1.93-2.12) among American Indian or Alaska Native youth, 0.63 (95% CI, 0.61-0.66) among Asian or Pacific Islander youth, 1.76 (95% CI, 1.73-1.79) among Black youth, and 0.89 (95% CI, 0.88-0.91) among Hispanic youth. From 2016 to 2020, the homicide rate in Black youth was 12.81 (95% CI, 12.52-13.10) per 100â¯000, which was 10.20 (95% CI, 9.75-10.66) times that of White youth. The suicide rate for American Indian or Alaska Native youth was 11.37 (95% CI, 10.30-12.43) per 100â¯000, which was 2.60 (95% CI, 2.35-2.86) times that of White youth. The firearm mortality rate for Black youth was 12.88 (95% CI, 12.59-13.17) per 100â¯000, which was 4.14 (95% CI, 4.00-4.28) times that of White youth. American Indian or Alaska Native youth had a firearm mortality rate of 6.67 (95% CI, 5.85-7.49) per 100â¯000, which was 2.14 (95% CI, 1.88- 2.43) times that of White youth. Black youth had an asthma mortality rate of 1.10 (95% CI, 1.01-1.18) per 100â¯000, which was 7.80 (95% CI, 6.78-8.99) times that of White youth. Conclusions and Relevance: In this study, racial and ethnic disparities were observed for almost all leading causes of injury and disease that were associated with recent increases in youth mortality rates. Addressing the increasing disparities affecting American Indian or Alaska Native and Black youth will require efforts to prevent homicide and suicide, especially those events involving firearms.

OBJECTIVES: The Louisiana Department of Health identified a need for greater outreach in low-income Black communities that addressed environmental asthma triggers. We piloted an asthma virtual home visit (VHV) program and evaluated its reach and ability to promote asthma self-management strategies in communities with a high prevalence of poorly controlled asthma. METHODS: Participants from Louisiana were continuously recruited into the VHV program starting in March 2021 and provided with asthma education materials. Participants reporting poorly controlled asthma and environmental triggers were also offered 3 VHVs with a respiratory therapist. All participants were asked to complete a preintervention and postintervention knowledge test, an Asthma Control Test (ACT) (maximum score = 25; scores ≤19 indicate poorly controlled asthma), and a final survey that assessed perceptions about asthma management and reduction of environmental triggers. RESULTS: As of October 2022, 147 participants were enrolled in the program, and 52 had consented to and received ≥1 VHV. Forty VHV recipients (77%) were aged <18 years, 40 (77%) were Black people, and 46 (88%) were from families with extremely low or low incomes. Asthma symptoms improved across all participants, with a median increase of 2.4 points on the ACT. Knowledge tests revealed that 86% of participants learned about ≥1 new asthma trigger; a larger percentage of VHV recipients than nonrecipients (68% vs 36%) had an improved knowledge test score postintervention. Compared with preintervention, about three-quarters of participants reported feeling more empowered to self-manage their asthma and a significant improvement in their quality of life postintervention. CONCLUSIONS: The program provided virtual asthma education to communities with a high burden of asthma and improved asthma outcomes for participants. Similar virtual models can be used to promote health equity, especially in areas with limited access to health care.

Rationale: The share of Black or Latinx residents in a census tract remains associated with asthma-related emergency department (ED) visit rates after controlling for socioeconomic factors. The extent to which evident disparities relate to the within-city heterogeneity of long-term air pollution exposure remains unclear. Objectives: To investigate the role of intraurban spatial variability of air pollution in asthma acute care use disparity. Methods: An administrative database was used to define census tract population-based incidence rates of asthma-related ED visits. We estimate the associations between census tract incidence rates and 1) average fine and coarse particulate matter, nitrogen dioxide (NO2), and sulfur dioxide (SO2), and 2) racial and ethnic composition using generalized linear models controlling for socioeconomic and housing covariates. We also examine for the attenuation of incidence risk ratios (IRRs) associated with race/ethnicity when controlling for air pollution exposure. Measurements and Main Results: Fine and coarse particulate matter and SO2 are all associated with census tract-level incidence rates of asthma-related ED visits, and multipollutant models show evidence of independent risk associated with coarse particulate matter and SO2. The association between census tract incidence rate and Black resident share (IRR, 1.51 [credible interval (CI), 1.48-1.54]) is attenuated by 24% when accounting for air pollution (IRR, 1.39 [CI, 1.35-1.42]), and the association with Latinx resident share (IRR, 1.11 [CI, 1.09-1.13]) is attenuated by 32% (IRR, 1.08 [CI, 1.06-1.10]). Conclusions: Neighborhood-level rates of asthma acute care use are associated with local air pollution. Controlling for air pollution attenuates associations with census tract racial/ethnic composition, suggesting that intracity variability in air pollution could contribute to neighborhood-to-neighborhood asthma morbidity disparities.

OBJECTIVE: To identify risk factors associated with hospital admission following an ED visit for asthma at the time of discharge among U.S. children and adults. METHODS: Asthma emergency department visits resulting in hospital admissions using discharge data among children (aged 0-17 years) and adults (aged 18 years or older) from the 2020 Nationwide Emergency Department Sample (NEDS), Healthcare Cost and Utilization Project (HCUP), Agency for Healthcare Research and Quality were examined. Risk factors associated with hospital admission following ED visits were identified using univariable and multi-variable logistic regression models. RESULTS: Among children, hospital admission after asthma-related ED visits was higher for females, ages less than 12 years, and discharged in January-March or in October-December and lower for Black children, Hispanic children, Medicaid or Medicare beneficiaries, other/no charge/self-pay, and in metropolitan non-teaching or non-metropolitan hospitals. Among adults, asthma ED visits resulting in hospital admissions were higher for females, ages 35 years or older, discharged in January-March, and for Medicare beneficiaries and lower for Black adults, Hispanic adults, adults of other races, other/no charge/self-pay, in metropolitan non-teaching or non-metropolitan hospitals, and median household income quartiles for patient's ZIP Code of less than $59,000 were lower. CONCLUSIONS: Sociodemographic factors, healthcare use, and household income were significantly associated with hospital admissions at the time of discharge from the ED. Examining hospital admission after an ED visit for asthma is important in identifying these groups and better addressing their healthcare needs.

Our objective was to investigate the distributions of six single nucleotide polymorphisms (SNPs) MS4A2 E237G, MS4A2 C-109T, ADRB2 R16G, IL4RA I75V, IL4 C-590T, and IL13 C1923T in Mauritian Indian and Chinese Han children with asthma. This case-control association study enrolled 382 unrelated Mauritian Indian children, 193 with asthma and 189 healthy controls, and 384 unrelated Chinese Han children, 192 with asthma and 192 healthy controls. The SNP loci were genotyped using polymerase chain reaction (PCR)-restriction fragment length polymorphism for the Chinese Han samples and TaqMan real-time quantitative PCR for the Mauritian Indian samples. In the Mauritian Indian children, there was a significant difference in the distribution of IL13 C1923T between the asthma and control groups (P=0.033). The frequency of IL13 C1923T T/T in the Mauritian Indian asthma group was significantly higher than in the control group [odds ratio (OR)=2.119, 95% confidence interval=1.048-4.285]. The Chinese Han children with asthma had significantly higher frequencies of MS4A2 C-109T T/T (OR=1.961, P=0.001) and ADRB2 R16G A/A (OR=2.575, P=0.000) than the control group. The IL13 C1923T locus predisposed to asthma in Mauritian Indian children, which represents an ethnic difference from the Chinese Han population. The MS4A2 C-109T T/T and ADRB2 R16G A/A genotypes were associated with asthma in the Chinese Han children.

Con el fin de investigar la rentabilidad de la prevención primaria del asma en lactantes de alto riesgo, de hasta 2 años, desde la perspectiva de la sociedad (PREVASC) y con un diagnóstico clínico de asma realizado por un médico generalista (MG) y un diagnóstico epidemiológico de asma basado en un modelo de predicción (EPM), se seleccionaron 476 lactantes de un ensayo aleatorizado y controlado (242 en el grupo de intervención, 234 en el grupo control). Por medio de informes semanales se evaluó la utilización de los recursos de salud. El margen de error acerca de los índices de rentabilidad incremental se determinó por análisis bootstrap. El 26.8% de los niños del grupo de intervención y el 25.5% de los controles recibieron el diagnóstico de asma por parte de un MG, mientras que el 69.9% y el 63.5%, respectivamente, tuvo el diagnóstico basado en un EPM. Con ambas definiciones no hubo diferencias en el diagnóstico de asma entre los participantes del grupo de intervención y el grupo control (odds ratio [OR]: 1.1, intervalo de confianza del 95% [IC]: 0.6-1.8 y OR: 1.3, IC: 0.8-2.2). La media de los costos totales en el grupo de intervención y el grupo control fue de 1564 euros (rango intercuartiles: 669-6 499 euros) y de 967 euros (rango intercuartiles: 29-7 136 euros). El índice de rentabilidad incremental del programa fue de -46 157 euros para el diagnóstico de asma por un MG y de -9 671 euros para la definición EPM, lo cual señala la inferioridad de la situación experimental. Todas las replicaciones bootstrap indicaron que el programa PREVASC es más costoso, con una probabilidad del 37% y del 13%, respectivamente, de que éste fuese más eficaz que la atención usual. La prevención primaria del asma en los primeros 2 años de vida no fue rentable con ambos modelos.

According to the 2002 census living ion chile 692.192 persons belonging to ethnic groups. Largest groups correspond to the mapuche ethnic group with 604.349 people. Not know the prevalence and caractheristics ofasthma in Chilean aboriginal groups. Worlwide while the number of publications is limited research shows that asthma prevalence is important in adult indigenous population of the Australia and United States. So well havedeveloped some interesting projects in Chile of interaction in health with the mapuche and huilliche communitiesnational studies are needed to enable the development of appropriate health policies for the management of asthma aboriginal populations.
Según el censo 2002 en Chile viven 692.102 personas pertenecientes a grupos étnicos. El grupo más grande corresponde a la etnia mapuche con 604.349 personas. Se desconoce la prevalencia y características del asma bronquial en grupos aborígenes chilenos. A nivel mundial si bien el número de publicaciones es reducido los estudios revelan que el asma presenta una prevalencia importante en población indígena adulta de Australia y Estados Unidos. Si bien en Chile se han desarrollado algunos proyectos interesantes de interacción en salud en comunidades mapuches y huilliches es necesario realizar estudios nacionales que permitan el desarrollo de políticas de salud adecuadas para el manejo del asma en poblaciones indígenas.

OBJETIVO: Analisar os significados culturais da asma infantil com origem na mãe-cuidadora. PROCEDIMENTOS METODOLÓGICOS: Pesquisa qualitativa realizada em 2004, no município de Fortaleza, CE. Foi utilizada a observação participante com abordagem etnográfica e entrevistas com sete mães acompanhantes de seus filhos em unidade de emergência hospitalar. Os significados das falas das mães foram identificados utilizando-se a técnica de análise temática. ANÁLISE DOS RESULTADOS: Foram identificadas duas categorias de discussão; na primeira, "desinformação sobre a doença", foi possível perceber que as mães não são informadas sobre a doença do filho. Na segunda categoria, "cuidado cultural", as mães referem informações sobre os cuidados e utilizam recursos do saber popular para prevenir a asma dos filhos, como o cuidado ambiental e a utilização de remédios caseiros à base de plantas medicinais. CONCLUSÕES: As características de desinformação e desconhecimento materno em relação à asma do filho mostram a necessidade de haver um trabalho educativo intenso, dialógico e problematizador em estreita colaboração com o tratamento, visando à melhoria do prognóstico da doença.

Para determinar algunas características epidemiológicas del asma en la costa caribe colombiana, se examinaron cuatro mil personas de Cartagena para establecer la prevalencia de esta enfermedad y los registros de defunciones ocurridas desde 1986 hasta 1990 en dos departamentos representativos del sector geográfico (Bolivar y Atlántico), con el fin de investigar la tendencia de la tasa de mortalidad por asma en ese período. Además, se investigó la importancia del asma entre otras enfermedades alérgicas haciendo un estudio poblacional con los pacientes que asistieron a un consultorio de alergias en Cartagena, en el cual se obtuvieron las frecuencias de las enfermedades alérgicas por la que consultaron. Los resultados mostraron una prevalencia de asma acumulativa y puntual de 8.8 por ciento y 12.2 por ciento respectivamente y una tasa de mostalidad en ascenso con valores que van desde 0.74 en 1986 hasta 1.62 en 1990. Setenta por ciento de la población general afectada por asma tenían menos de 15 años de edad y en la consulta de alergias se observó que el asma era la segunda enfermedad más frecuente después de la rinitis. Los datos de estos estudios sugieren que la frecuencia de asma es alta, la mortalidad por dicha enfermedad no es muy diferente a la encontrada en otros sitios y la distribución de las enfermedades alérgicas muestra un predominio de los procesos respiratorios.
