Stressful childhood experiences increase risk of multiple chronic conditions
Published on 15 August 2024
New research shows that people who have faced traumatic or stressful events during childhood, such as abuse or neglect, have a higher risk of experiencing multiple long-term health conditions in adulthood.
University of Dundee research has revealed that each additional traumatic or stressful event experienced during childhood increases the odds of an individual suffering from multiple chronic conditions later in life by nearly 13%.
An adverse childhood experience (ACE) is a potentially traumatic or stressful event that occurs before the age of 18. They can include a wide variety of negative experiences, including abuse, neglect, household dysfunction, and other forms of stress such as bullying, famine or war.
ACEs have previously been associated with increased risk of many different poor health and social outcomes in adult life. However, their cumulative effect on the likelihood of someone suffering from simultaneous chronic health conditions, also known as multimorbidity, during adulthood is still unclear.
To establish the impact of ACEs on long-term health conditions, a team in the University’s School of Medicine, led by Dr Dhan Senaratne, conducted a systematic review and meta-analysis of 25 studies involving over 370,000 people.
Dr Senaratne, Clinical PhD Fellow, said, “As global populations continue to age, we are seeing an increase of people with multiple long-term health conditions.
“The natural implication is to think that is a problem that affects adults in mid or later life, but our research suggests that the origins may occur decades earlier in childhood.
“Data reveals that the more types of adversity you experience during your childhood, the more likely you are to have multiple long term health conditions, or multimorbidity, when you are an adult.
“The statistical analysis revealed that for every childhood adversity you experience, the likelihood of you having multimorbidity in later life is 12.9% higher.”
The paper ‘The impact of adverse childhood experiences on multimorbidity: a systematic review and meta‑analysis’ has been published in the BMC Medicine journal.
Dr Senaratne emphasised that while the research strengthens evidence supporting the lasting influence of childhood conditions on adult health and wellbeing, it does not establish whether ACEs are a direct cause of multimorbidity.
However, he said that future work on prevention and identification methods for ACEs may be beneficial in reducing risk for long-term health conditions.
“The increase of long-term health conditions within populations increases the complexity and cost of healthcare provision,” said Dr Senaratne. “If we want to address this, it may be necessary to include some strategies that also address childhood circumstances.
“There is an increased focus on developing trauma-informed models of healthcare, in which the impact of negative life experiences is incorporated into the assessment and management of long-term health conditions.
“However, identifying factors early in the cause of multimorbidity may help to mitigate the consequences of this developing healthcare crisis.”
This research is part of the Consortium Against Pain Inequality (CAPE), a multicentre programme of research involving researchers from the Universities of Dundee, Aberdeen, Edinburgh, Stirling, and University College London.
CAPE is investigating how ACEs affect chronic pain using a range of different research methods.
