Systemic inequities in education and health: How structural barriers to learning perpetuate global longevity disparities

Indigenous education models, such as those of the Māori (*whare wānanga*) or Navajo (*Diné*), centre land-based learning and collective well-being, demonstrating that longevity is not solely tied to formal schooling but to cultural continuity and ecological harmony. These systems have been disrupted by settler-colonial education policies (e.g., residential schools in Canada, Australia’s Stolen Generations) that severed intergenerational knowledge transfer, directly correlating with higher mortality rates in Indigenous populations. The study’s focus on Western metrics of education obscures these lived realities.

The link between education and longevity is not new; 19th-century public health reforms in Europe and Japan showed that mass education reduced mortality by enabling health literacy and civic participation. However, colonial education systems in Africa and Asia were designed to produce compliant labourers rather than critical thinkers, embedding structural inequities that persist today. The study’s ahistorical framing ignores how structural adjustment programs in the 1980s-90s forced Global South nations to cut education budgets, exacerbating health disparities—a cycle that continues under IMF loan conditions.

Cross-culturally, education’s role in longevity is mediated by cultural values; for instance, in Kerala, India, high female literacy rates (achieved through grassroots education movements) correlate with lower infant mortality, even amid poverty, due to community-driven health practices. In contrast, in the U.S., the privatisation of education has created 'education deserts' in Black and Latino communities, where school closures and underfunded districts directly reduce life expectancy. The study’s Western lens misses these nuanced, culturally specific pathways.

The study’s statistical approach—using imputed data to overcome gaps in global records—advances methodological rigor in global health research, particularly for low-data contexts. However, its reliance on years of schooling as a proxy for education ignores qualitative dimensions like curriculum quality, cultural relevance, and critical thinking skills, which are harder to quantify but equally vital for longevity. Future research should integrate mixed-methods designs to capture these dimensions.

Artistic and spiritual traditions often frame longevity as a byproduct of harmony—whether through Ayurveda’s emphasis on *dinacharya* (daily routines) in India, Traditional Chinese Medicine’s balance of *qi*, or African spiritual practices that view health as a communal covenant. These frameworks suggest that education’s role in longevity may be less about formal credentials and more about cultivating wisdom, resilience, and ecological reciprocity. The study’s secular, metric-driven approach overlooks these embodied knowledges.

If current trends persist, the global longevity gap will widen as education privatisation and austerity policies deepen, particularly in post-colonial nations where IMF loan conditions restrict public spending. Scenario modelling suggests that investing in community-controlled education—such as Brazil’s *Escola Sem Partido* or Finland’s equity-focused schools—could reduce premature mortality by 20-30% within a generation. Conversely, continued neoliberal education reforms may entrench health disparities for decades.

Marginalised communities—such as Roma in Europe, Dalit women in South Asia, or Indigenous peoples in the Americas—face systemic barriers to education that directly shorten lifespans, from segregated schools to language suppression. Their exclusion from the study reflects a broader pattern of epistemic violence, where their knowledge systems are deemed irrelevant to 'objective' research. Amplifying these voices requires decolonising education metrics and centring lived experiences in policy design.
