Infantile mistreatment accelerates organic aging

Infantile mistreatment leaves lasting consequences that go far beyond physical and psychological injuries. For example, Scientific data has long been showing that children victims of mistreatment. In addition, negligence run an increased risk of chronic diseases, mental disorders and premature deaths throughout their lives. Furthermore, A new study specifies the mechanisms.

Behind the ill -treated children.

A Japanese study advances knowledge – Infantile mistreatment accelerates organic aging

To fill these shortcomings. a research team from the University of Fukui in Japan conducted a study examining both organic aging and the social behavior of young children. Their results. which have just been published in the leading scientific journal PLOS Oneshed light on the way in which child abuse accelerates organic aging and harms social development.

For this, the researchers studied 96 children aged 4 to 5, comparing infantile mistreatment accelerates organic aging 36 having undergone serious mistreatment at 60 in normal development. They measured organic aging by analyzing the methylation profiles of DNA (chemical marks posed on genetic material which allow the cell to decide which genes must be activated. deactivated, without changing the DNA code itself) using a new method whose team was pioneer during their previous work. These molecular signatures. captured from the genetic material of oral samples, essentially indicate the cellular speed of the body of a child. In addition. they used oculometry technology to monitor the social attention patterns of children, by measuring the duration during which they looked at different elements in carefully selected video sequences.

Accelerated organic aging

The team found that children victims of mistreatment had an accelerated biological aging compared to those. with normal development. In addition, they spent much less time looking at their eyes when presented them with human faces videos. This infantile mistreatment accelerates organic aging decrease in the attention paid to the eyes (an essential aspect of social interaction. understanding) suggests differences in the way in which social information treats social information. In addition. the acceleration of organic aging and the reduction of visual contact were both strongly linked to higher scores to the measures of emotional and behavioral difficulties, determined using tools based on questionnaires.

Infantile mistreatment can therefore leave invisible, but measurable traces, on the biological and social development of the child. These results highlight the importance of early intervention. support for ill -treated children in order to mitigate the long -term effects of accelerated aging and sociocognitive deficits.
