Our health, wellbeing and behavior are shaped by our childhood experiences. Exposure to trauma or intense stress, referred to as “adverse childhood experiences” (Aces) by experts, is linked to a multitude of negative outcomes later in life. These include an increased risk of developing physical and mental health problems, engaging in risky behavior, experiencing violence and lower educational attainment.

My colleagues and I wanted to understand the effect that childhood trauma may have on our relationships with healthcare professionals. We also wanted to gauge the level of comfort people had when visiting health settings. Our new research shows that Aces can be linked to distrust in health services and lower levels of comfort in hospitals and clinics.

The types of Aces that academic studies measure can vary. They typically include experiencing physical, emotional or sexual abuse, parental separation or divorce, growing up in a home where there is domestic violence or abuse, mental illness, drug or alcohol misuse, or where a household member has been in prison. Unfortunately, Aces are relatively common.

Research conducted in the UK has found that around half of people report they have experienced at least one Ace, while around one in ten report four or more Aces. And studies in more vulnerable populations find a much higher level of Aces, with more than half of male prisoners in one UK study reporting four or more Aces. Aces are thought to influence neurological and emotio.
