Association of a Housing Mobility Program With Childhood Asthma Symptoms and Exacerbations

Residential relocation and changes in patterns of environmental exposures by health determinants among children and adolescents in Catalonia, Spain

Residential relocation leads to environmental changes, besides being likely to be influenced by sociodemographic characteristics. The relationship between them is, however, still not well described. We aimed to investigate changes in patterns of urban, natural and physical environmental exposures due to relocation and related sociodemographic determinants in a population-based cohort study of children and adolescents. We included individuals between 0 and 17 years of age, registered in primary healthcare records in Catalonia, Spain from 2006 to 2018 and categorized them as non-movers and movers (first residential change). Hierarchical clustering identified groups of individuals based on their exposure to air pollution, green spaces and built environment. Low, medium and high environmental hazard exposure clusters were identified, which were used to identify changes in environmental exposure patterns due to relocation, namely same, worse, and better environment. Multinomial logistic regression determined whether sex, age, nationality and area-level deprivation influenced these changes. From 1,316,138 individuals, 221,058 were movers. Compared to non-movers, movers were more frequently with foreign nationality (12.1% vs. 21.3%, respectively) and more likely to live in the most deprived areas at baseline (19.2% vs. 24.4%). Younger children had higher risk of moving to better or worse environments. Individuals living in areas with the highest levels of deprivation were least likely to move within the same environments (i.e., either moving to better (Odds Ratio [95% Confidence Interval] 1.39[1.34-1.44]) or worse environment (1.56[1.49-1.63])). Compared to people from Spain, those from Africa moved to similar environments (OR of moving to a better environment 0.90 (0.87-0.94) with respect to move to the same environment, and OR of moving to a worse environment 0.82 (0.78-0.85)), those from America tended to move to other environments (1.17 (1.12-1.23) better and 1.09 (1.03-1.15) worse), while those from Asia and Europe moved to better environments (1.22 (1.12-1.33) and 1.20 (1.14-1.27) respectively). No associations were found for sex. Changes in patterns of environmental exposures due to residential mobility are complex and may be determined by age, deprivation and nationality.

Interventions addressing systemic racism in the US: A scoping review

Previous studies have reported on the health impact of systemic racism among historically oppressed populations. In fact, there is an emerging body of literature, including systematic reviews, which describe the negative health consequences of systemic racism among racial/ethnic minoritized groups in the US. Less is known, however, about effective intervention strategies to address systemic racism and the resulting health inequities. This scoping review was conducted to synthesize the published literature on U.S.-based interventions designed to improve health equity by addressing systemic racism. The Preferred Reporting Items for Systematic Reviews and Meta-analyses extension for scoping review (PRISMA-ScR) checklist was used to report this review. We searched six databases (MEDLINE, CINAHL, PsycINFO, Sociological Abstracts, Web of Science Core Collection, and Scopus) to examine the intervention studies. A total of 172 articles were included in review. These interventions were classified by typology which included healing-centered approaches, community-based interventions targeting health disparities, diversity, equity, inclusion (DEI) efforts, anti-racism training interventions, and policy interventions. The findings from this review have important implications for the development, testing, and scaling of interventions designed to addressed systemic racism.

Research Priorities in Pediatric Asthma Morbidity: Addressing the Impacts of Systemic Racism on Children with Asthma in the United States. An Official American Thoracic Society Workshop Report

Background: In the United States, Black and Latino children with asthma are more likely than White children with asthma to require emergency department visits or hospitalizations because of an asthma exacerbation. Although many cite patient-level socioeconomic status and access to health care as primary drivers of disparities, there is an emerging focus on a major root cause of disparities-systemic racism. Current conceptual models of asthma disparities depict the historical and current effects of systemic racism as the foundation for unequal exposures to social determinants of health, environmental exposures, epigenetic factors, and differential healthcare access and quality. These ultimately lead to biologic changes over the life course resulting in asthma morbidity and mortality. Methods: At the 2022 American Thoracic Society International Conference, a diverse panel of experts was assembled to identify gaps and opportunities to address systemic racism in childhood asthma research. Panelists found that to examine and address the impacts of systemic racism on children with asthma, researchers and medical systems that support biomedical research will need to 1) address the current gaps in our understanding of how to conceptualize and characterize the impacts of systemic racism on child health, 2) design research studies that leverage diverse disciplines and engage the communities affected by systemic racism in identifying and designing studies to evaluate interventions that address the racialized system that contributes to disparities in asthma health outcomes, and 3) address funding mechanisms and institutional research practices that will be needed to promote antiracism practices in research and its dissemination. Results: A thorough literature review and expert opinion discussion demonstrated that there are few studies in childhood asthma that identify systemic racism as a root cause of many of the disparities seen in children with asthma. Community engagement and participation in research studies is essential to design interventions to address the racialized system in which patients and families live. Dissemination and implementation studies with an equity lens will provide the multilevel evaluations required to understand the impacts of interventions to address systemic racism and the downstream impacts. To address the impacts of systemic racism and childhood asthma, there needs to be increased training for research teams, funding for studies addressing research that evaluates the impacts of racism, funding for diverse and multidisciplinary research teams including community members, and institutional and financial support of advocating for policy changes based on study findings. Conclusions: Innovative study design, new tools to identify the impacts of systemic racism, community engagement, and improved infrastructure and funding are all needed to support research that will address impacts of systemic racism on childhood asthma outcomes.

Neighborhood-level variability in asthma-related emergency department visits in Central Texas

BACKGROUND

The extent to which incidence rates of asthma-related emergency department (ED) visits vary from neighborhood to neighborhood and predictors of neighborhood-level asthma ED visit burden are not well understood.

OBJECTIVE

We aimed to describe the census tract-level spatial distribution of asthma-related ED visits in Central Texas and identify neighborhood-level characteristics that explain variability in neighborhood-level asthma ED visit rates.

METHODS

Conditional autoregressive models were used to examine the spatial distribution of asthma-related ED visit incidence rates across census tracts in Travis County, Texas, and assess the contribution of census tract characteristics to their distribution.

RESULTS

There were distinct patterns in ED visit incidence rates at the census tract scale. These patterns were largely unexplained by socioeconomic or selected built environment neighborhood characteristics. However, racial and ethnic composition explained 33% of the variability of ED visit incidence rates across census tracts. The census tract predictors of ED visit incidence rates differed by racial and ethnic group.

CONCLUSIONS

Variability in asthma ED visit incidence rates are apparent at smaller spatial scales. Most of the variability in census tract-level asthma ED visit rates in Central Texas is not explained by racial and ethnic composition or other neighborhood characteristics.

Increasing awareness regarding the relationship between environmental exposures and allergic disease

This review highlights studies from the past 3 years that add to the understanding of the impact of environmental exposures on allergic disease. These include aeroallergens, air quality, prenatal or early-life exposures, and occupational exposures. Recent studies have focused on the relationship between the environment, the microbiome, and allergic disease, and new therapeutic options have also been reviewed. Lastly, there has been significant recent research improving our knowledge of the link between health disparities and environmental exposures. These scientific advances have resulted in a better understanding that sets the foundation for current and future research dedicated to improving health outcomes by modifying environmental exposures.

Advocacy and Health Equity: The Role of the Pediatric Pulmonologist

Pediatric pulmonologists have the expertise to be advocates in many areas that affect the respiratory health of children. This article provides an overview of selected advocacy topics related to health equity and provides key examples that can improve child respiratory health in the clinical encounter and beyond.

Child Opportunity Index Mobility, Recurrent Wheezing, and Asthma in Early Childhood: A Population-Based Prospective Cohort Study

We prospectively examined associations between mobility in neighborhood opportunity and early childhood recurrent wheezing/asthma. Downward mobility was associated with developing asthma, but not recurrent wheezing, though associations were attenuated after adjusting for family-level socioeconomic status. Elucidating how neighborhoods impact asthma may inform asthma equity initiatives in early childhood.

A Scoping Review to Identify Community- and Societal-Level Strategies Evaluated from 2013 to 2023 for Their Potential Impact on Child Well-Being in the United States

There is increased recognition for solutions that address the social determinants of health (SDOHs)-the context in which families are raising children. Unfortunately, implementing solutions that address inequities in the SDOHs has proven to be difficult. Many child and family serving systems and communities do not know where to start or do not have the capacity to identify and implement upstream SDOH strategies. As such, we conducted a scoping review to assess the status of evidence connecting strategies that address the SDOHs and child well-being. A total of 29,079 records were identified using natural language processing with 341 records meeting inclusion criteria (e.g., outcomes focused on child well-being, interventions happening at a population level, and evaluations of prevention strategies in the United States). Records were coded, and the findings are presented by the SDOH domain, such as strategies that addressed economic stability (n = 94), education access and quality (n = 17), food security (n = 106), healthcare access and quality (n = 96), neighborhood and built environment (n = 7), and social and community context (n = 12). This review provides an overview of the associations between population-level SDOH strategies and the impact-good and bad-on child well-being and may be a useful resource for communities and practitioners when considering equitable solutions that promote thriving childhoods.

Asthma Pathogenesis: Phenotypes, Therapies, and Gaps: Summary of the Aspen Lung Conference 2023

Although substantial progress has been made in our understanding of asthma pathogenesis and phenotypes over the nearly 60-year history of the Aspen Lung Conferences on asthma, many ongoing challenges exist in our understanding of the clinical and molecular heterogeneity of the disease and an individual patient's response to therapy. This report summarizes the proceedings of the 2023 Aspen Lung Conference, which was organized to review the clinical and molecular heterogeneity of asthma and to better understand the impact of genetic, environmental, cellular, and molecular influences on disease susceptibility, heterogeneity, and severity. The goals of the conference were to review new information about asthma phenotypes, cellular processes, and cellular signatures underlying disease heterogeneity and treatment response. The report concludes with ongoing gaps in our understanding of asthma pathobiology and provides some recommendations for future research to better understand the clinical and basic mechanisms underlying disease heterogeneity in asthma and to advance the development of new treatments for this growing public health problem.

Housing assistance among patients with cancer: SEER-Medicare US Department of Housing and Urban Development data linkage

BACKGROUND

Lack of stable, affordable housing is an important social determinant of health. Federal housing assistance may buffer against housing vulnerabilities among low-income households, but research examining the association of housing assistance and cancer care has been limited. We introduce a new linkage of Surveillance, Epidemiology, and End Results (SEER) program-Medicare and US Department of Housing and Urban Development (HUD) administrative data.

METHODS

Individuals enrolled in HUD public and assisted housing programs between 2006 and 2021 were linked with cancer diagnoses between 2006 and 2019 identified in the SEER-Medicare data from 16 states using Match*Pro (National Institutes of Health, Bethesda, MD) probabilistic linkage software. HUD administrative data include timing and type of housing assistance as well as verified household income. Medicare administrative data are available through 2020.

RESULTS

A total of 335 490 unique individuals who received housing assistance at any time point, including 156 794 who received housing assistance around the time of their diagnosis (at least 6 months before diagnosis until 6 months after diagnosis or death), were matched to SEER-Medicare data. A total of 63 251 individuals receiving housing assistance at the time of their diagnosis were aged 66 years and older and continuously enrolled in Medicare parts A and B fee for service; 12 035 had a diagnosis of lung cancer, 8866 of breast cancer, 7261 of colorectal cancer, and 4703 of prostate cancer.

CONCLUSIONS

This novel data linkage will be available through the National Cancer Institute and can be used to explore the ways in which housing assistance is associated with cancer diagnosis, care, and outcomes, including the role of housing assistance status in potentially reducing or contributing to inequities across racialized and ethnic groups.

The effects of violence and related stress on asthma

In the United States, people living in deprived urban areas and persons in certain minoritized groups are often exposed to violence and affected with asthma, and epidemiologic studies have shown a link between exposure to violence (ETV) and asthma throughout the lifespan. Indeed, ETV at the individual, intrafamilial and community levels has been linked to asthma in children and adults. In this review, we discuss the evidence for a causal relation between ETV and asthma, emphasizing findings published in the last five years. Interpretation of the available evidence is limited by variable quality of the assessment of ETV or asthma, potential recall and selection bias, inability to estimate the relative contribution of various types of violence to the observed associations, lack of objective biomarkers of asthma or asthma endotypes, and inconsistent consideration of potential confounders or modifiers of the ETV-asthma link. Despite such limitations, the aggregate evidence from studies conducted in different locations and populations suggests that ETV affects asthma and asthma outcomes, and that this is explained by direct physiologic effects of violence-related distress and indirect effects (e.g., through risky health behaviors or co-morbidities). Thus, large prospective studies with careful assessment of specific types of ETV, key covariates and comorbidities (including mental illness), and asthma are needed to advance this field. Such research efforts should not preclude screening for maltreatment in children with asthma and ETV-related depression and anxiety in adolescents and adults with asthma. Further, vigorous policies are needed to curtail violence, as such policies could benefit patients with asthma while saving lives.

The Child Opportunity Index 2.0 and exacerbation-prone asthma in a cohort of urban children

RATIONALE

Social determinants of health underlie disparities in asthma. However, the effects of individual determinants likely interact, so a summary metric may better capture their impact. The Child Opportunity Index 2.0 (COI) is one such tool, yet its association with exacerbation-prone (EP) asthma is unknown.

OBJECTIVE

To investigate the association between the COI and EP asthma and clinical measures of asthma severity in children.

METHODS

We analyzed data from two prospective observational pediatric asthma cohorts (n = 193). Children were classified as EP (≥1 exacerbation in the past 12 months) or exacerbation-null (no exacerbations in the past 5 years). Spirometry, exhaled nitric oxide, IgE, and Composite Asthma Severity Index (CASI) were obtained. The association between COI and EP status was assessed with logistic regression. We fit linear and logistic regression models to test the association between COI and each clinical measure.

RESULTS

A 20-point COI decrease conferred 40% higher odds of EP asthma (OR 1.4; 95%CI 1.1-1.76). The effect was similar when adjusted for age and sex (OR 1.38, 95%CI 1.1-1.75) but was attenuated with additional adjustment for race and ethnicity (OR 1.19, 95%CI 0.92-1.54). A similar effect was seen for the Social/Economic and Education COI domains but not the Health/Environment Domain. A 20-point COI decrease was associated with an increase in CASI of 0.34. COI was not associated with other clinical measures.

CONCLUSIONS

Lower COI was associated with greater odds of EP asthma. This highlights the potential use of the COI to understand neighborhood-level risk and identify community targets to reduce asthma disparities.

Maternal stressful life events during pregnancy and childhood asthma and wheeze

BACKGROUND

Studies have linked prenatal maternal psychosocial stress to childhood wheeze/asthma but have rarely investigated factors that may mitigate risks.

OBJECTIVE

To investigate associations between prenatal stress and childhood wheeze/asthma, evaluating factors that may modify stress effects.

METHODS

Participants included 2056 mother-child dyads from Environmental influences on Child Health Outcomes (ECHO)-PATHWAYS, a consortium of 3 prospective pregnancy cohorts (the Conditions Affecting Neurocognitive Development and Learning in Early Childhood study, The Infant Development and Environment Study, and a subset of the Global Alliance to Prevent Prematurity and Stillbirth study) from 6 cities. Maternal stressful life events experienced during pregnancy (PSLEs) were reported using the Pregnancy Risk Assessment Monitoring System Stressful Life Events questionnaire. Parents reported child wheeze/asthma outcomes at age 4 to 6 years using standardized questionnaires. We defined outcomes as ever asthma, current wheeze, current asthma, and strict asthma. We used modified Poisson regression with robust standard errors (SEs) to estimate risk ratios (RRs) and 95% CI per 1-unit increase in PSLE, adjusting for confounders. We evaluated effect modification by child sex, maternal history of asthma, maternal childhood traumatic life events, neighborhood-level resources, and breastfeeding.

RESULTS

Overall, we observed significantly elevated risk for current wheeze with increasing PSLE (RR, 1.09 [95% CI, 1.03-1.14]), but not for other outcomes. We observed significant effect modification by child sex for strict asthma (P interaction = .03), in which risks were elevated in boys (RR, 1.10 [95% CI, 1.02-1.19]) but not in girls. For all other outcomes, risks were significantly elevated in boys and not in girls, although there was no statistically significant evidence of effect modification. We observed no evidence of effect modification by other factors (P interactions > .05).

CONCLUSION

Risk of adverse childhood respiratory outcomes is higher with increasing maternal PSLEs, particularly in boys.

Impact of climate change on paediatric respiratory health: pollutants and aeroallergens

Paediatric populations are particularly vulnerable to respiratory diseases caused and exacerbated by aeroallergens, pollutants and infectious agents. Worsening climate change is expected to increase the prevalence of pollutants and aeroallergens while amplifying disease severity and causing disproportionate effects in under-resourced areas. The purpose of this narrative review is to summarise the role of anthropogenic climate change in the literature examining the future impact of aeroallergens, pollutants and infectious agents on paediatric respiratory diseases with a focus on equitable disease mitigation. The aeroallergens selected for discussion include pollen, dust mites and mould as these are prevalent triggers of paediatric asthma worldwide. Human rhinovirus and respiratory syncytial virus are key viruses interacting with climate change and pollution and are primary causal agents of viral respiratory disease. Within this review, we present the propensity for aeroallergens, climate change and pollution to synergistically exacerbate paediatric respiratory disease and outline measures that can ameliorate the expected increase in morbidity and severity of disease through a health equity lens. We support shifting from fossil fuels to renewable energy worldwide, across sectors, as a primary means of reducing increases in morbidity.

Lower socioeconomic status may help explain racial disparities in asthma and atopic dermatitis prevalence: A mediation analysis

BACKGROUND

Racial disparities in atopic disease (atopic dermatitis [AD], asthma, and allergies) prevalence are well documented. Despite strong associations between race and socioeconomic deprivation in the United States, and socioeconomic status (SES) and atopic diseases, the extent to which SES explains these disparities is not fully understood.

OBJECTIVE

We sought to identify racial disparities in childhood atopic disease prevalence and determine what proportion of those disparities is mediated by SES.

METHODS

This study used the National Health Interview Survey (2011-2018) to investigate AD, asthma, and respiratory allergy prevalence in Black and White children and the extent to which measures of SES explain any identified disparities.

RESULTS

By race, prevalences were as follows: AD, White 11.8% (95% CI: 11.4%, 12.2%) and Black 17.4% (95% CI: 16.6%, 18.3%); asthma prevalence, White 7.4% (95% CI: 7.0%, 7.7%) and Black 14.3% (95% CI: 13.5%, 15.0%); respiratory allergy, White 11.4% (95% CI: 11.0%, 11.9%) and Black 10.9% (95% CI: 10.3%, 11.6%). The percentage of the disparity between racial groups and disease prevalence explained by a multivariable measure of SES was 25% (95% CI: 15%, 36%) for Black versus White children with AD and 47% (95% CI: 40%, 54%) for Black versus White children with asthma.

CONCLUSIONS

In a nationally representative US population, Black children had higher prevalence of AD and asthma than White children did and similar prevalence of respiratory allergy; a multivariable SES measure explained a proportion of the association between Black versus White race and AD and a much larger proportion for asthma.

Impact of socioeconomic factors on allergic diseases

Allergic and immunologic conditions, including asthma, food allergy, atopic dermatitis, and allergic rhinitis, are among the most common chronic conditions in children and adolescents that often last into adulthood. Although rare, inborn errors of immunity are life-altering and potentially fatal if unrecognized or untreated. Thus, allergic and immunologic conditions are both medical and public health issues that are profoundly affected by socioeconomic factors. Recently, studies have highlighted societal issues to evaluate factors at multiple levels that contribute to health inequities and the potential steps toward closing those gaps. Socioeconomic disparities can influence all aspects of care, including health care access and quality, diagnosis, management, education, and disease prevalence and outcomes. Ongoing research, engagement, and deliberate investment of resources by relevant stakeholders and advocacy approaches are needed to identify and address the impact of socioeconomics on health care disparities and outcomes among patients with allergic and immunologic diseases.

Housing Insecurity and Asthma Outcomes

Asthma is a chronic respiratory disease with widespread prevalence that affects children, adolescents, and adults. Asthma morbidity and mortality can be exacerbated in the setting of housing insecurity. In this Grand Rounds Review article, we present a case and discuss the implications that housing insecurity has on asthma outcomes in the United States. We then highlight ways in which providers can advocate for patients with asthma and housing insecurity.

Impact of income-based public drug coverage deductibles on adherence to asthma medications

BACKGROUND

Cost-related nonadherence to medications can be a barrier to asthma management.

OBJECTIVE

To quantify the impact of public drug plan deductibles on adherence to asthma medications.

METHODS

We used a quasi-experimental regression discontinuity analysis to determine whether thresholds in deductibles for public drug coverage, determined on the basis of annual household income, decreased medication use among lower-income children and adults with asthma in British Columbia from 2013 to 2018. Using dispensed medication records, we evaluated deductible thresholds at annual household incomes of $15,000 (a deductible increase from 0% to 2% of annual household income), and $30,000 (a deductible increase from 2% to 3% annual household income). We evaluated medication costs, use, the ratio of inhaled corticosteroids-containing controller medications to total medications, excessive use of short-acting β-agonists, and the proportion of days covered by controller therapies. All costs are reported in 2020 Canadian dollars.

RESULTS

Overall, 88,935 individuals contributed 443,847 person-years of follow-up (57% of female sex, mean age 31 years). Public drug subsidy decreased by -$41.74 (95% CI, -$28.34 to -$55.13) at the $15,000-deductible threshold, a 28% reduction, and patient costs increased by $48.45 (95% CI, $35.37-$61.53). The $30,000 deductible threshold did not affect public drug costs (P = .31), but patient costs increased by $27.65 (95% CI, $15.22-$40.09), which is an 11% increase. Asthma-related medication use, inhaled corticosteroids-to-total medication ratio, excessive use of short-acting β-agonists, and proportion of days covered by controller therapies were not impacted by deductible thresholds.

CONCLUSION

Income-based deductibles reduced public drug costs with no effect on asthma-related medication use, adherence to controller therapies, or excessive reliever therapy use in lower-income individuals with asthma.

Neighborhood Opportunity and Vulnerability and Incident Asthma Among Children

Background

The extent to which physical and social attributes of neighborhoods play a role in childhood asthma remains understudied.

Objective

To examine associations of neighborhood-level opportunity and social vulnerability measures with childhood asthma incidence.

Design, Setting, and Participants

This cohort study used data from children in 46 cohorts participating in the Environmental Influences on Child Health Outcomes (ECHO) Program between January 1, 1995, and August 31, 2022. Participant inclusion required at least 1 geocoded residential address from birth and parent or caregiver report of a physician's diagnosis of asthma. Participants were followed up to the date of asthma diagnosis, date of last visit or loss to follow-up, or age 20 years.

Exposures

Census tract-level Child Opportunity Index (COI) and Social Vulnerability Index (SVI) at birth, infancy, or early childhood, grouped into very low (<20th percentile), low (20th to <40th percentile), moderate (40th to <60th percentile), high (60th to <80th percentile), or very high (≥80th percentile) COI or SVI.

Main Outcomes and Measures

The main outcome was parent or caregiver report of a physician's diagnosis of childhood asthma (yes or no). Poisson regression models estimated asthma incidence rate ratios (IRRs) associated with COI and SVI scores at each life stage.

Results

The study included 10 516 children (median age at follow-up, 9.1 years [IQR, 7.0-11.6 years]; 52.2% male), of whom 20.6% lived in neighborhoods with very high COI and very low SVI. The overall asthma incidence rate was 23.3 cases per 1000 child-years (median age at asthma diagnosis, 6.6 years [IQR, 4.1-9.9 years]). High and very high (vs very low) COI at birth, infancy, or early childhood were associated with lower subsequent asthma incidence independent of sociodemographic characteristics, parental asthma history, and parity. For example, compared with very low COI, the adjusted IRR for asthma was 0.87 (95% CI, 0.75-1.00) for high COI at birth and 0.83 (95% CI, 0.71-0.98) for very high COI at birth. These associations appeared to be attributable to the health and environmental and the social and economic domains of the COI. The SVI during early life was not significantly associated with asthma incidence. For example, compared with a very high SVI, the adjusted IRR for asthma was 0.88 (95% CI, 0.75-1.02) for low SVI at birth and 0.89 (95% CI, 0.76-1.03) for very low SVI at birth.

Conclusions

In this cohort study, high and very high neighborhood opportunity during early life compared with very low neighborhood opportunity were associated with lower childhood asthma incidence. These findings suggest the need for future studies examining whether investing in health and environmental or social and economic resources in early life would promote health equity in pediatric asthma.

Why Current Therapy Does Not Cure Asthma. Is It Time to Move Towards a One Health Approach?

Asthma continues to be a disease for which there is no cure, even if it can be very well controlled with the appropriate therapies, which take into account the specific phenotype. The paradox of asthma is that asthma can heal spontaneously, albeit in a small percentage of cases. This observation is highly relevant, since understanding the mechanisms of spontaneous healing can pave the way for new strategies for treating asthma. It is likely that the lack of cure for asthma is due to the fact that current therapies target downstream mediators of the inflammatory response. Asthma can be considered a response of maladaptation of the airway epithelium to the environment, through the orientation of the innate immunity towards an inflammatory response. The important effect of the environment on asthma progress comes from interventions which help children who live in disadvantaged urban neighborhoods move to higher resourced neighborhoods. It is quite interesting that the magnitude of decrease of exacerbations associated with moving was larger than the effect of inhaled corticosteroids and similar to that observed for the effect of biologic agents. Alpine altitude climate treatment is a natural treatment that targets biological pathway, improving various outcomes such as asthma control and quality of life, exacerbation rate and hospitalizations. If as researchers we want to set ourselves the goal of achieving complete remission of asthma, without the need for ongoing maintenance treatment, we need to change the approach to finding new asthma treatment strategies. The One Health approach, an interdisciplinary strategy with focal point on human, animal, and environmental health interconnections, appears to be the right tool for researching asthma prevention and treatment.
