$6.2 Million: NIH Funded a Study on Asthma in Transgender Patients. Asthma Is Real. The Population Framing Is the Question.
NIH NHLBI Funded $6.2 Million to Study Asthma Mechanisms and Treatment Outcomes Specifically in Transgender Individuals
The National Heart, Lung, and Blood Institute awarded a multi-year R01 grant for research into asthma outcomes, mechanisms, and treatment responses in transgender populations. The scientific basis is not implausible: published literature documents higher rates of asthma and respiratory conditions among transgender individuals, potentially attributable to hormone therapy effects on lung function, social stress pathways, and environmental exposures associated with gender nonconformity. DOGE flagged the grant as part of a broader review of NIH transgender health research, which collectively totaled hundreds of millions in active grants.
The policy question DOGE raises is not whether asthma is real — it is — or even whether transgender individuals have different health outcomes. The question is whether $6.2 million in NHLBI discretionary grant funding is best allocated to a population-specific study of approximately 1.6 million individuals, versus continuing research into asthma mechanisms affecting 25 million Americans. NIH prioritization decisions involve real tradeoffs between population-specific research and broadly applicable basic science.
NIH’s transgender health research portfolio expanded significantly under Biden — from a handful of grants in 2016 to dozens of active R01s, program projects, and center grants by 2024. House Energy and Commerce Committee Republicans compiled a list of what they characterized as politicized research spending, with this asthma study among the examples. NIH defended each grant on individual scientific merit as reviewed by peer-review study sections. The Trump administration’s review did not engage with individual scientific merit but applied a categorical rule: grants studying “gender ideology” were subject to termination.
