Understanding the biology linking childhood trauma to long-term health problems
Children who experience abuse or neglect, or grow up in unstable environments, have a greater risk of health problems including asthma, cognitive delays, obesity, heart disease and cancer, throughout their lives, a growing body of evidence suggests. To understand why, researchers are looking at the measureable physical changes that adverse childhood experiences (ACEs) cause to young brains and bodies. The hope is that identifying these biomarkers will help pinpoint which children are most at risk for health problems, and provide targets for treatment.
One promising area of research involves the stress hormone cortisol. In infancy, interactions with caregivers shapes the way bodies learn to handle stress. In the absence of supportive caregiving, this system may not develop properly.
