Childhood Abuse Can Lead to Health Problems Later

A new research study suggests the immune system may be damaged by childhood trauma leading to increased vulnerability to a range of health problems in later life.

Trauma was defined as as experiencing sexual, physical, or emotional abuse, neglect, or separation from caregivers before the age of 17.

Investigators from King’s College London found heightened inflammation across three blood biomarkers in adults who had been victims of childhood trauma. High levels of inflammation can lead to serious and potentially life-threatening conditions such as type II diabetes, cardiovascular disease, as well as the onset of psychiatric disorders.

The study has been published in the journal Molecular Psychiatry.

Previous research has shown that childhood trauma increases vulnerability to several psychiatric disorders, including depression, anxiety, psychosis, and post-traumatic stress disorder (PTSD), as well as several chronic physical health problems, including arthritis, cardiovascular disease, lung disease, and cancer.

However, the biological pathway mediating vulnerability for these health problems has, until now, been unclear.

The researchers conducted a meta-analysis of 25 studies which previously investigated the association between childhood traumatic experiences and markers of inflammation in adulthood. The final sample comprised more than 16,000 people, including healthy participants and patients with psychiatric disorders or physical illnesses.

As well as the association between childhood trauma and increased blood inflammation, the researchers found that different types of trauma — emotional, physical, or sexual abuse — affected these biomarkers in different ways.

For instance, physical and sexual abuse was associated with significantly increased levels of two biomarkers — tumour necrosis factor-α (TNF-α) and interleukin-6 (IL-6), whereas heightened levels of c-reactive protein (CRP) appeared to be primarily related to parental absence during early child development.

Dr Valeria Mondelli from the Department of Psychological Medicine comments: “Our findings are important not only because they help us to understand more about why people with a history of childhood trauma may develop psychiatric disorders or physical problems in adulthood, but also because they open the possibility of prevention and treatment strategies for these individuals.

“For instance, using these inflammatory markers might make it possible to identify victims of childhood trauma who are at higher risk of developing physical or mental health problems, and to test potential treatments which could decrease inflammation in these individuals.”

Mondelli also explained that although different types of trauma are associated with different types of inflammation, the reason for this remains unclear. While there are several factors which may offer some insight including the age and length of exposure to childhood trauma and the victim’s relationship with the perpetrator, further research is indicated to discover the molecular mechanisms behind these associations.

She concluded: “Understanding the biological consequences of childhood trauma may be crucial for identifying why some individuals go on to develop physical or psychiatric disorders following these traumatic experiences, whereas other remain resilient in face of similar traumatic exposure.”
