🟢 Strong Evidence
Compulsory and free basic education policies reduced offspring mortality by approximately 9% in low-income and middle-income countries (LMICs), according to a quasi-experimental analysis published in The Lancet Global Health (2026). However, educational disruptions from COVID-19 appear to have substantially reversed these mortality gains, highlighting how school closures can have cascading effects on child health beyond direct classroom instruction.
Key takeaways
- Compulsory and free basic education policies reduced offspring mortality by approximately 9% in LMICs, with greatest benefits in the poorest households
- COVID-19 school closures led to substantial increases in modelled offspring mortality due to interrupted instruction time and loss of educational services
- Educational disruptions pose a critical public health risk that extends far beyond academic outcomes, affecting maternal and child health trajectories

How education policies protect child survival
The analysis examined the relationship between compulsory and free basic education policy implementation and reductions in offspring mortality across LMICs. The mechanisms underlying this protective effect operate through multiple pathways: improved maternal literacy and health knowledge, increased household income through improved employment prospects, delayed childbearing through extended school enrolment, and enhanced access to health information and services. According to The Lancet Global Health (2026), the benefits were particularly pronounced in the poorest households, where compulsory education policies reduced offspring mortality by 12–14%, compared to 5–7% in middle-income households.
This finding aligns with broader evidence on education as a social determinant of health. Research on maternal education and child survival has consistently documented that each additional year of maternal schooling is associated with reduced under-five mortality, particularly in settings with limited healthcare infrastructure where household knowledge becomes the primary health intervention.
COVID-19 disruptions reversed protective gains
The modelling component of the study projected substantial increases in offspring mortality when educational instruction time was interrupted during COVID-19 lockdowns. According to The Lancet Global Health analysis (2026), the interruption of schooling reversed mortality gains accumulated over previous decades, particularly affecting the most vulnerable populations. The effect size suggests that each month of school closure was associated with measurable increases in modelled offspring mortality risk in LMICs.
This finding reflects multiple mechanisms: loss of nutritional support from school feeding programmes, reduced supervision and care for younger siblings while older children were in school, interrupted access to health services delivered through schools (immunisations, contraception, mental health support), and reduced maternal economic productivity when childcare demands increased. The research documenting health consequences of school closures indicates that the mortality impact extends beyond direct health services to encompass household economic and social disruption.
Equity implications: why poorest households suffer most
The analysis revealed substantial variation in policy effectiveness and vulnerability to disruption according to baseline household wealth. In the poorest households, both the protective effect of education policies and the harmful effect of disruptions were most pronounced. This reflects the reality that in very low-income settings, education serves not only as knowledge transfer but as a critical lifeline for nutrition, childcare, contraception access, and economic stability. The Lancet Global Health (2026) emphasises that the poorest populations lack alternative safety nets to buffer against educational disruption.
Conversely, wealthier households in the same countries have greater ability to absorb school closures through private tutoring, internet access, and maintained household income during lockdowns. This concentration of harm in the poorest households underscores how COVID-19 educational disruptions may have widened health inequalities within LMICs, reversing decades of mortality progress among the most vulnerable children.
Policy implications and forward priorities
The evidence points to urgent need for policies designed to minimise educational disruptions and strengthen the resilience of school-based health and nutrition services. WHO guidance on maternal and child health increasingly recognises education as a foundational intervention, yet school systems remain vulnerable to closure during crises. Building redundancy into essential school services—particularly nutrition support, immunisation, and contraception access—could preserve mortality benefits during future disruptions.
For countries that have not yet implemented free basic education, the analysis provides robust evidence of mortality benefit that justifies investment. For countries currently recovering from pandemic-related closures, the findings suggest that rapid restoration of full in-person schooling, combined with catch-up nutrition and health services, should be prioritised as a public health intervention with direct implications for child survival.
Compulsory and free basic education policies reduced offspring mortality by approximately 9% in low-income and middle-income countries, with greatest protective effect in the poorest households. However, COVID-19-related educational disruptions substantially reversed these mortality gains through mechanisms including loss of school nutrition programmes, interrupted childcare, and reduced maternal economic participation.

What this means
Frequently asked questions
Why does education reduce child mortality if it is not a direct health intervention?
Education operates through multiple pathways. Educated mothers have greater health literacy, delayed childbearing, higher household income, and improved ability to navigate healthcare systems. In low-income settings, schools provide critical nutrition support, childcare that enables maternal work, and direct health services including immunisations and contraception. These combined effects translate to measurable reductions in offspring mortality according to The Lancet Global Health (2026) analysis.
How large was the mortality increase from COVID-19 school closures?
The modelling study projected substantial increases in offspring mortality during periods of educational disruption, with effect sizes varying by household wealth. The poorest households faced the greatest mortality risk from closures. The Lancet Global Health (2026) indicates that each month of interrupted instruction time contributed measurably to modelled mortality increases, though the specific percentage increase is dependent on baseline mortality rates and duration of closure in each setting.
Do these findings apply only to very low-income countries?
The analysis specifically examined low-income and middle-income countries, where benefits were most pronounced. The mechanisms—education improving maternal health knowledge, delaying childbearing, and enabling access to health services—are most impactful in settings with limited baseline healthcare infrastructure. However, The Lancet Global Health (2026) notes that education remains a documented health determinant across income levels, and school closures pose risks to child health universally.
The evidence that educational policies reduce offspring mortality in LMICs is now sufficiently robust to inform international development priorities. As countries implement recovery programmes following pandemic disruptions, protecting educational continuity should rank alongside vaccination and nutrition programmes as a core child survival intervention. Future crises must be managed with explicit recognition that school closures carry population health consequences that extend for decades through their effects on maternal education and household economic stability.
