Global mortality gap widens for children and adolescents with disabilities
Childhood mortality has fallen across much of the world, yet this synthesis shows that survival remains sharply unequal for young people with disabilities. Across 29 cohort studies representing more than 35 million children and adolescents, mortality was consistently higher in the disabled group than among peers without disabilities, and the difference was large enough to resist easy explanation by chance alone.
Overall, children and adolescents with disabilities faced a 5.31-fold higher risk of all-cause death, with a 95% confidence interval of 3.63 to 7.77 and a p value below 0.001. The spread between studies was substantial, with an I2 of 98% and tau of 0.88, which signals wide variation in how disability was defined, measured, and analyzed across settings. Even so, the direction of effect did not change: mortality was higher in every major age stratum examined.
The clinical message is blunt. Disability in childhood is not only a matter of function, participation, or schooling; it is also linked to survival.
The mortality excess was strongest in early childhood
Age separated the signal, but it did not weaken it. Among children aged 0 to 5 years, the hazard ratio for death reached 7.51, with a 95% confidence interval of 4.70 to 12.00, p below 0.001, tau of 0.44, and I2 of 91%. In the 6 to 19 year age group, mortality remained elevated at 4.68, with a 95% confidence interval of 2.26 to 9.69, p below 0.001, tau of 0.93, and I2 of 96%.
Early childhood is the period when congenital conditions, feeding difficulties, infection vulnerability, and delays in accessing care can exact their greatest toll. For children with disabilities, these risks can stack quickly: a baseline impairment may interact with poor nutrition, missed vaccinations, respiratory compromise, delayed recognition of illness, or a health system that is not designed to accommodate mobility, communication, or sensory needs. The result is not a single pathway but a convergence of biological fragility and structural exclusion.
One finding stands out for its size.
Neurological disabilities carried the steepest mortality burden
Disability type mattered, and neurological disability showed the most pronounced association with death. The hazard ratio reached 11.71, with a 95% confidence interval of 7.90 to 17.35, p below 0.001, tau of 0.19, and I2 of 76%.
This is clinically plausible. Neurological conditions often bring feeding impairment, aspiration risk, seizures, tone abnormalities, motor disability, and dependence on caregivers for daily survival tasks. Those complications can raise mortality directly, but they also raise the odds that treatable problems are recognized late or managed incompletely. In settings where pediatric rehabilitation, assistive devices, and specialist follow-up are sparse, the gap between need and care can widen rapidly.
The review also included children with other impairment categories, but the paper’s central message does not hinge on one diagnosis group. The mortality difference appeared across disability types, which argues against a narrow explanation based only on a single congenital condition or rare disorder.
What the review included and how the evidence was assembled
Investigators prospectively registered the review in PROSPERO and searched Embase, Global Health, MEDLINE, PubMed, and PsycInfo for studies published from January 1, 2000 through August 20, 2026. The analysis included cohort and other longitudinal studies comparing children and adolescents with and without disabilities, limited to participants aged 0 to 19 years.
Twenty-nine studies met inclusion criteria. Sixteen provided data suitable for meta-analysis, and 26 comparative analyses were used in the quantitative synthesis. The methods were intentionally broad on effect size, allowing hazard ratios, mortality rate ratios, odds ratios, and standardized mortality ratios when available, provided the study design included a comparator group and a clear disability definition.
Disability was operationalized through functional limitation, activity limitation, self-report, registration, certification, or specific impairment and condition categories such as cerebral palsy, spina bifida, visual impairment, hearing impairment, and intellectual and developmental disability. That breadth strengthened scope, but it also introduced heterogeneity. Different ascertainment tools capture different children, and the threshold for identifying disability can shift with local policy, diagnostic access, and cultural practice.
Why the mortality gap likely reflects more than impairment alone
The paper places the mortality gap in a broader social and health-system context. Children with disabilities are more likely to face exclusion from education, poverty, stigma, social isolation, violence, and abuse. Those exposures affect nutrition, development, caregiver support, and timely healthcare use. They can also influence whether a child reaches care at all, whether symptoms are recognized, and whether treatment is adapted to their needs.
Health-system barriers are part of the mechanism. Inaccessible services, limited professional training in disability care, and poor accommodation for communication or mobility needs can turn manageable illness into preventable death. When a child cannot physically enter a clinic, cannot communicate symptoms, or is not recognized as needing urgent attention, mortality becomes a systems problem as much as a medical one.
The elevated risk seen here is unlikely to be explained by impairment alone. The diversity of disabilities included in the review makes that plain. Biological vulnerability matters, but so do the conditions under which children live, learn, and seek care.
Evidence gaps remain largest where need is greatest
The review is strongest in what it aggregates and weakest in where it cannot reach. Substantial between-study heterogeneity limits precision. Disability definitions varied. Effect measures varied. Some studies relied on administrative records, others on self-report or clinical classification. Those differences make pooled estimates useful, but not tidy.
The geographic distribution of evidence is another constraint. The number of studies from low-income and middle-income countries was small, even though most children with disabilities live in those settings. That imbalance matters because the drivers of mortality can differ sharply when specialized care, rehabilitation, nutrition support, and emergency services are scarce.
What the review can say with confidence is narrow and important: children and adolescents with disabilities die more often than their peers without disabilities. What it cannot yet say is which interventions narrow the gap most effectively, or how much of the excess mortality is preventable with early identification, inclusive primary care, rehabilitation, nutrition support, and better family and community services.
The next evidence needed is not another estimate of the gap. It is practical data on how to close it.
