The burden of pediatric respiratory disease remains disproportionately high in low- and middle-income countries (LMICs) and underserved populations globally. Despite this, research efforts and resource allocation in pediatric pulmonology have historically concentrated on high-income settings, leaving substantial gaps in evidence-based care for the most vulnerable children.
Pediatric respiratory conditions, including pneumonia, asthma, tuberculosis, and chronic lung disease of prematurity, contribute significantly to childhood morbidity and mortality worldwide.1 The World Health Organization estimates that pneumonia alone accounts for approximately 700,000 deaths annually in children under five years of age, with the vast majority occurring in LMICs.2 Despite this substantial disease burden, research infrastructure and funding for pediatric pulmonary investigations are often concentrated in high-income countries, leading to a paucity of evidence directly applicable to the unique epidemiological and resource-constrained environments of LMICs.3 This disparity results in diagnostic and therapeutic strategies that may not be feasible, affordable, or culturally appropriate for the populations most affected by these diseases.4
Addressing the Research Imbalance
The ATS 2026 session, "PEDIATRIC PULMONARY RESEARCH IN GLOBAL HEALTH AND UNDERSERVED POPULATIONS: IT’S A SMALL WORLD," aims to highlight these critical research gaps and foster collaborative efforts to address them. The session emphasizes the need for research that focuses on prevalent conditions in LMICs, such as severe acute respiratory infections, the long-term pulmonary sequelae of early childhood infections, and the impact of environmental exposures like household air pollution.5 For instance, while significant advancements have been made in managing asthma in high-income settings, the diagnosis and management of asthma in LMICs are often complicated by limited access to spirometry, inhaled corticosteroids, and specialist care.6
Furthermore, the session is expected to discuss the importance of developing and validating diagnostic tools that are suitable for low-resource settings. Current diagnostic methods for conditions like pediatric tuberculosis often rely on sophisticated laboratory techniques that are unavailable in many parts of the world.7 Research into point-of-care diagnostics and simplified clinical algorithms could significantly improve early detection and treatment initiation.8 The session will also likely underscore the necessity of implementation science research, which focuses on translating effective interventions into routine clinical practice within specific contexts, considering local health systems and community factors.9 This includes evaluating the effectiveness of vaccination programs, improved nutrition, and access to clean cooking fuels in reducing the burden of pediatric respiratory disease.10
The session is a call to action for the global pediatric pulmonology community to reorient research priorities. It advocates for increased investment in research capacity building within LMICs, fostering equitable partnerships, and ensuring that research outcomes directly inform policy and practice in the regions where they are most needed.11 The goal is to move beyond simply acknowledging disparities to actively generating the evidence required to improve respiratory health outcomes for all children, regardless of their geographic location or socioeconomic status.12
The persistent imbalance in pediatric pulmonary research is not merely an academic concern; it directly impacts the daily practice of clinicians in LMICs. When evidence is primarily derived from high-resource settings, it creates a vacuum for local practitioners who must then extrapolate or adapt guidelines, often without robust data to support their decisions. This can lead to suboptimal care, delayed diagnoses, and inefficient use of scarce resources. For example, the widespread use of bronchodilators for presumed asthma in children in settings where spirometry is unavailable may mask other treatable conditions or delay appropriate interventions for severe pneumonia.
From an industry perspective, the lack of targeted research in global health populations represents a missed opportunity and a moral imperative. Developing diagnostics and therapeutics specifically tailored for LMICs, such as heat-stable vaccines, affordable inhaled corticosteroids, or rapid, low-cost TB tests, could address massive unmet needs. Pharmaceutical companies and medical device manufacturers should be incentivized to invest in these areas, perhaps through public-private partnerships or tiered pricing models, rather than solely focusing on markets with higher purchasing power. The current landscape means that many children in LMICs are treated with older, less effective, or more expensive interventions simply because newer, more appropriate options have not been developed or tested for their context.
Ultimately, the patients, the children, bear the brunt of this research disparity. Their access to evidence-based care is limited, and their health outcomes suffer. The call for more equitable research is not about charity; it is about recognizing that every child deserves the benefit of scientific advancement. Until research priorities align with global disease burden, the promise of universal health coverage for pediatric respiratory conditions will remain an aspiration rather than a reality.
- The Pivot The ATS 2026 session "PEDIATRIC PULMONARY RESEARCH IN GLOBAL HEALTH AND UNDERSERVED POPULATIONS: IT’S A SMALL WORLD" directly addresses the disparity in research focus.
- The Data While no specific trial data is presented, the session highlights the urgent need for context-specific research to address conditions like severe pneumonia, tuberculosis, and chronic lung disease of prematurity in LMICs.
- The Action Clinicians and researchers should advocate for and participate in studies designed for and conducted within global health settings to generate actionable evidence for these populations.
