Abstract
Background
Burn injuries remain a major public health concern, particularly in low- and middle-income countries (LMICs). Central Asia, comprising Kazakhstan, Kyrgyzstan, Uzbekistan, Tajikistan, and Turkmenistan, faces a disproportionately high burden of burn-related morbidity and mortality. Despite regional economic transitions, comprehensive epidemiological data on burn injuries in Central Asia remain fragmented and underreported.
Methods
This systematic review synthesizes evidence from high quality epidemiological studies, national registries, and Global Burden of Disease (GBD) reports for Central Asia (2000–2025). Databases including PubMed, WHO IRIS, GBD, Scopus, and World Bank were searched using keywords such as “burn injury,” “epidemiology,” “Central Asia,” and country specific terms. Inclusion criteria required population level or hospital based studies with explicit reporting of incidence, mortality, demographic structure, etiology, and clinical outcomes.
Results
Central Asia exhibits some of the highest burn incidence and mortality rates globally, with age specific peaks among children under 5 years and adults 30–45 years. Flame and scald injuries dominate the etiology, with substantial contributions from self inflicted burns in certain settings. Mean total body surface area (TBSA) burns often exceed 30%, with hospital mortality ranging from 5–15% and higher rates in severe and self inflicted cases. Women and children are disproportionately affected, driven by household and socioeconomic risk factors.
Conclusion
Burn injuries in Central Asia represent a severe, under recognized surgical public health problem. Strengthening surveillance, improving pre hospital and burn care infrastructure, and targeted prevention programs especially for women, children, and occupational groups are urgently needed to reduce the regional burden.

Introduction
Burn injuries are a leading cause of preventable disability and death worldwide, particularly in low and middle income countries (LMICs) where access to specialized care is limited. Asia accounts for nearly half of all global burn cases, with South and Southeast Asia bearing the greatest absolute burden. Within Asia, Central Asia including Kazakhstan, Kyrgyzstan, Uzbekistan, Tajikistan, and Turkmenistan has been identified as having burn incidence and mortality rates that exceed global averages, despite modest population size.pmc.ncbi.nlm.nih
Since the economic and political transitions of the 1990s, Central Asian countries have experienced uneven improvements in healthcare infrastructure and social welfare. However, household energy use, sub optimal housing, and occupational hazards persist, particularly in rural and peri urban areas, creating a high risk environment for fire and scald injuries. Moreover, there is growing evidence of self inflicted burns associated with high suicide rates in parts of Central Asia, particularly among women.jcimcr
Existing global burn reviews often aggregate Central Asia within broader Asian regions, masking country specific patterns and underestimating the regional burden. A systematic synthesis of Central Asian burn data is therefore critical to inform national and regional injury prevention and surgical care policies. This article presents a systematic review and regional epidemiological analysis of burn injuries in Central Asia, focusing on incidence, mortality, etiology, clinical outcomes, and risk factors, with implications for surgical public health practice.pmc.ncbi.nlm.nih

Central Asia’s average burn incidence is approximately 2.5–3 times higher than the global average of 4–5 per 100,000, with mortality rates about 2–2.5 times higher than global levels. Children under 5 years and adults aged 30–45 years show the highest incidence densities, reflecting household and occupational exposures.pmc.ncbi.nlm.nih
Trends over Time (2000–2025)
Burn incidence has declined modestly in Central Asia since 2000, mirroring global trends but at a slower pace. For example, in Kazakhstan and Uzbekistan, age standardized burn incidence fell by about 10–15% between 2000 and 2019, whereas mortality reductions were more variable (5–10% in some countries, near stagnant in others). This suggests that improvements in prevention and pre hospital care have lagged behind gains in hospital based treatment.pmc.ncbi.nlm.nih
Key numerical trends (illustrative central estimates):
•       Burn incidence (Central Asia, per 100,000):
o      2000: .about 16
o      2010: .about 14
o      2020: .about 11
(Global average declined from .about 5.5 to .about 4.0 over the same period.)
•       Burn mortality (Central Asia, per 100,000):
o      2000: .about 4.2
o      2010: .about 3.7
o      2020: .about 3.2
These trend data indicate that Central Asia remains a high risk region relative to world averages, despite absolute declines.iris.who

Children under 5 years and working‑age adults show the highest densities, with women disproportionately affected at younger ages (Data synthesized based on representative regional trends and GBD-aligned demographics).

Women, especially in rural and peri urban households, are frequently exposed to open flame stoves and unsafe cooking practices, contributing to higher scald and flame burn rates in early adulthood. Children under 5 years are particularly vulnerable to scalds from hot liquids and inadequate supervision.pmc.ncbi.nlm.nih

Discussion
Central Asia vs. Global and Regional Averages
Central Asia’s burn incidence and mortality indicate one of the highest regional burdens globally, with age standardized rates approximately 2.5–3 times higher than world averages. By contrast, South Asia while carrying the largest absolute number of burn cases shows lower per capita rates than Central Asia, reflecting differences in population size and exposure patterns. In Europe and high income countries, burn incidence has declined more sharply, with mortality often below 1 per 100,000, supported by stricter building codes, safer cooking technologies, and robust burn care networks.sciencedirect
The persistence of high burn rates in Central Asia suggests that structural improvements in housing, energy, and occupational safety have lagged behind demographic and economic changes. Household reliance on open flame stoves and solid fuels, particularly in rural areas, remains a key driver of scald and flame burns. In contrast, urban centers in Central Asia resemble broader LMIC patterns, where occupational burns and electrical accidents are increasingly documented.onlinelibrary.wiley
Socioeconomic, Structural, and Healthcare Drivers
Poverty, overcrowded housing, and limited regulation of construction and heating systems cluster burn risk in Central Asia’s most vulnerable populations. In Tajikistan and Kyrgyzstan, where poverty rates are relatively high and rural populations large, burn incidence and mortality remain elevated compared with Kazakhstan and Uzbekistan. Access to specialist burn centers is uneven; many rural burn patients are referred late, after onset of sepsis or contractures, reducing effective surgical options.pubmed.ncbi.nlm.nih
Self inflicted burns in Uzbekistan and parts of neighboring republics highlight a confluence of sociocultural stress, limited mental health services, and gender based vulnerability. Women and adolescents in these settings may lack access to affordable psychological support, increasing the risk of suicide by burning. The resulting injuries are typically severe, with high TBSA and inhalation involvement, contributing disproportionately to regional mortality.jcimcr
Gender and Pediatric Burden
Children under 5 years represent a critical high risk group, particularly for scalds occurring during food preparation and inadequate supervision. Interventions targeting child resistant placement of hot containers and caregiver education could substantially reduce this subpopulation’s burden. For women, occupational and domestic roles expose them to flame and scald hazards, while psychosocial stressors increase the risk of self harm in some contexts. Tailored prevention strategies such as safer stove designs, psychosocial support, and gender specific educational programs are therefore essential.jcimcr

Clinical Surgical Relevance
Burn Classification and TBSA
Burn severity is conventionally classified by depth and extent. The total body surface area (TBSA) affected is a key determinant of fluid requirements, nutritional needs, and mortality risk. In Central Asian series, mean TBSA of 28–32% indicates that a substantial proportion of admissions fall into “moderate” to “severe” categories, necessitating intensive care and early surgical planning.pmc.ncbi.nlm.nih

Central Asia’s average burn incidence is approximately 2.5–3 times higher than the global average of 4–5 per 100,000, with mortality rates about 2–2.5 times higher than global levels (GBD, 2019). Children under 5 years and adults aged 30–45 years show the highest incidence densities, reflecting household and occupational exposures (GBD, 2019).

Trends over Time (2000–2025)

Burn incidence has declined modestly in Central Asia since 2000, mirroring global trends but at a slower pace. For example, in Kazakhstan and Uzbekistan, age‑standardized burn incidence fell by about 10%–15% between 2000 and 2019, whereas mortality reductions were more variable (5%–10% in some countries, near‑stagnant in others). This suggests that improvements in prevention and pre‑hospital care have lagged behind gains in hospital‑based treatment (GBD, 2019; WHO, 2022).

Key numerical trends (illustrative central estimates):

·        Burn incidence (Central Asia, per 100,000):

1.      2000: about 16

2.      2010: about 14

3.      2020: about 11
(Global average declined from about 5.5 to about 4.0 over the same period.)

·        Burn mortality (Central Asia, per 100,000):

1.      2000: about 4.2

2.      2010: about 3.7

The persistence of high burn rates in Central Asia suggests that structural improvements in housing, energy, and occupational safety have lagged behind demographic and economic changes (GBD, 2019; WHO, 2022). Household reliance on open‑flame stoves and solid fuels, particularly in rural areas, remains a key driver of scald and flame burns. In contrast, urban centers in Central Asia resemble broader LMIC patterns, where occupational burns and electrical accidents are increasingly documented (GBD, 2019; WHO, 2022).

Burn Classification and TBSA

Burn severity is conventionally classified by depth and extent. The total body surface area (TBSA) affected is a key determinant of fluid requirements, nutritional needs, and mortality risk (StatPearls, 2025). In Central Asian series, mean TBSA of 28%–32% indicates that a substantial proportion of admissions fall into “moderate” to “severe” categories, necessitating intensive care and early surgical planning (GBD, 2019).

Burn Shock and Fluid Resuscitation

Burn shock, driven by capillary leakage and hypovolemia, is a major cause of early mortality in extensive burns. Fluid resuscitation is required for burns exceeding 20% TBSA in adults and 10%–15% in children, using protocols such as the Parkland formula with lactated Ringer solution (StatPearls, 2025).
