Summary: Unique DNA methylation shifts in Syrian refugee babies were triggered by war-related genes that were involved in brain development and stress response. These genetic changes suggest possible long-term effects on health and advancement, different from other traumas like poverty.
Additionally, the study found that women have more genetic responses than boys, which highlights how vulnerable they are. The research highlights the deep biological and psychological effects that war has had on younger people. These results provide new information on the genetic makeup of trauma and its effects on health.
Important Information:
- Important genes for brain function and pressure rules have been linked to DNA methyl changes caused by war coverage.
- Ladies showed more important DNA changes than males, suggesting higher risk.
- The study found that children exposed to conflict may have slower genetic aging, which might have an impact on development.

According to a groundbreaking study from the University of Surrey, children living in war-torn nations never only suffer from poor mental health benefits, but also that combat may lead to harmful genetic changes at the DNA level that could have a long-term impact on their health.  ,
In the first research of its kind, the research team collected saliva samples from 1, 507 Syrian refugee children, aged 6 to 19, living in informal communities in Lebanon.
They conducted an analysis of DNA methylation ( DNAm ), an epigenetic procedure that adds chemical tags to DNA at various locations throughout the genome ( the set of genes ) to determine the extent of the process. Without altering the DNA code, these DNAm changes you turn on or off genes.  ,
Surveys, completed by both the kids and their caregivers, were used to calculate exposure to the war-related occasions experienced by the baby.  ,
Surrey – in collaboration with University College London, Institute for Development, Research, Advocacy and Applied Care, Lebanon, St Georges University Lebanon, and a leading international NGO – found that youngsters who had been exposed to combat situations showed DNA m shifts at various places and areas in the genome.
Some of these modifications were attributed to genes involved in crucial processes like intracellular transport and neurotransmission ( how materials move within cells ).  ,  ,
These particular changes, which are unobserved in various forms of trauma like bullying and poverty, suggest that war may induce particular physiological responses in the body.  ,
The National Institutes of Health ( NIH) provides funding for this study.  ,
 , Professor Michael Pluess, head author of the study from the School of Psychology at the University of Surrey, said:  ,
Our study has found proof of the natural methods underlying this result, despite it being well known that war has a negative impact on children’s mental health. Additionally, we discovered that combat may have a bearing on children’s enhancement because it is related to slower epigenetic ageing.  ,
Our study provides a more in-depth understanding of the dreadful cost of war, beyond the emotional strain and for the many millions of children who are ensnared in it, all told. ”  ,
This report is piece of the , BIOPATH research,  , a demographic study which began in 2017. The first comprehensive review of its kind conducted among immigrant children is BIOPATH, which will help us understand how pain affects mental health development.  ,
Additionally, the researchers examined whether boys ‘ and girls ‘ biological effects of war differed. They discovered that girls who went through a war had more important DNA m changes than boys, mainly in genes related to brain development and stress response.
Girls showed a stronger physiological response to combat exposure, suggesting that they may be more prone to the long-term effects of stress at a molecular level despite being affected by both boys and girls.  ,
In a normal process, small chemical molecules, known as methyl groups, are added to particular DNA regions. These individuals act like relays, changing the expression of genes or altering their expression levels. Importantly, this does n’t change the actual DNA sequence itself.  ,  ,
DNA m is a significant component of ordinary development, and diet, stress, and trauma exposure can all play a role. Serious events, like war, can cause DNA m to change, which could have an impact on a person’s long-term physical and mental health. Researchers research these changes to realize how physical trauma can have a profound impact on the body.  ,

Abstract
Children and adolescents from Syrian refugee who have been exposed to conflict risk DNA methylation
Importance
Poor mental health outcomes are related to combat coverage. Long-lasting DNA imprinting changes can result from severe and traumatic events, which could explain the relationship between adversity and psychological health.
We are currently unable to fully understand the physiological effects of war contact because of the limited number of studies that have been conducted on the effect of war on DNA methylation in young children or adolescents.
Objective
To discover oral DNA methylation variations between refugee children and adolescents who have been exposed to war.
Design, Setting, and Participants ,  ,
Syrian migrant children and adolescents were included in this cohort study, and their main caregivers were chosen from Lebanon’s tentacled communities. Data collection was carried out in 2 ripples, 1 year off, from October 2017 to January 2018 and October 2018 to January 2019. Children and their caregiver were interviewed, and babies provided saliva tests for DNA recovery. Data analysis was conducted in 2022, 2023, and 2024.
Exposure
The War Events Questionnaire was used to interview kids and their caregivers and assess their level of involvement in the war.
Main Result and Measures ,  ,
The Infinium MethylationEPIC BeadChip ( Illumina ) was used to measure the salivary DNA methylation levels. Using a set of already-existing genetic aging clocks, an acceleration of epigenetic aging was calculated. A writing research revealed earlier unidentified DNA methylation correlations with childhood pain.
Results
The study population included 1507 children and adolescents ( mean]SD] age, 11.3]2.4] years, age range, 6-19 years, 793 female]52.6 % ] ). In the first year, 1449 kids received saliva samples for DNA recovery, and 872 children received samples in the second year.
There were a number of unevenly methylated locations and regions in kids who reported war events. Enrichment analyses indicated an enhancement of dna sets associated with membranes transport, neurotransmission, and cellular motion in genes that exhibited variable methylation.
Numerous sex-specific DNA methylation differences were identified as a result of sex-specific analyses of battle coverage. Just 2 of 258 ( 0.8 % ) previously reported trauma-associated DNA methylation places were associated with war contact ( B = −0.004, 95 % CI, −0.005 to −0.003, Bonferroni , P = .04 and B = −0.005, 95 % CI, −0.006 to −0.004, Bonferroni , P = .03 ).
Any war contact or assault was officially associated with decreased genetic time using the Horvath multitissue clock ( B = −0.39, 95 % CI, −0.63 to −0.14,  , P = .007 and B = −0.42, 95 % CI, −0.73 to −0.11,  , P = .002 ).
Opinions and Relevance ,  ,
War contact was linked to a number of distinctive differences in oral DNA methylation in this group of Syrian migrant children and adolescents.
