Understanding Adverse Childhood Experiences (ACEs)

Lecture Notes on Adverse Childhood Experiences (ACEs)

Introduction

  • In the mid-90s, CDC and Kaiser Permanente identified that childhood trauma significantly increases the risk of leading causes of death in the USA.
  • High doses of trauma affect brain development, the immune system, hormonal systems, and DNA transcription.
  • Those exposed to severe trauma have triple the lifetime risk of heart disease and lung cancer, and a 20-year reduction in life expectancy.
  • Doctors lack training in routine screening and treatment for childhood trauma.

Definition of Trauma

  • Focus on severe and pervasive threats that change physiology.
  • Types of trauma:
    • Abuse (physical, emotional, sexual)
    • Neglect
    • Growing up with a parent with mental illness or substance dependence
    • Other severe stressors (incarceration, domestic violence, parental separation/divorce)

Professional Background

  • Initially, viewed trauma as either a social problem (refer to social services) or a mental health problem (refer to mental health services).
  • Worked at California Pacific Medical Center, opening a clinic in Bayview-Hunters Point, a severely underserved area.
  • Focused on health disparities (access to care, immunization rates, asthma hospitalization rates).

Shift in Understanding

  • Many children referred for ADHD had histories of severe trauma rather than ADHD.
  • Realized the need to understand how adversity affects development.
  • Came across the Adverse Childhood Experiences Study (ACEs) by Dr. Vince Felitti and Dr. Bob Anda.

Adverse Childhood Experiences Study

  • Surveyed 17,500 adults about their exposure to ACEs.
  • ACEs include:
    • Physical, emotional, or sexual abuse
    • Physical or emotional neglect
    • Parental mental illness or substance dependence
    • Incarceration or domestic violence
    • Parental separation or divorce
  • Each affirmative response increased an individual's ACE score.

Key Findings

  • ACEs are common: 67% of the population has at least one ACE; 12.6% have four or more.
  • Correlation between ACE score and poor health outcomes:
    • Higher ACE scores correlate with increased risk of various diseases.
    • For example, ACE score of 4+ correlates with 2.5 times higher risk of chronic obstructive pulmonary disease (COPD) and hepatitis, 4.5 times higher risk of depression, and 12 times higher risk of suicidality.
    • ACE score of 7+ triples the risk of lung cancer and increases the risk of ischemic heart disease by 3.5 times.

Neurological Impact

  • ACEs affect brain structure and function:
    • Areas affected include the nucleus accumbens (pleasure/reward), prefrontal cortex (impulse control/executive function), and amygdala (fear response).
  • Even without high-risk behaviors, individuals with high ACE scores are still at a greater risk for chronic diseases due to changes in the stress response system (HPA axis).

Response and Treatment

  • Created the Center for Youth Wellness in San Francisco to address ACEs and toxic stress.
  • Routine screening for all children during physical exams.
  • Multidisciplinary treatment for children with positive ACE scores, focusing on reducing adversity and treating symptoms.
  • Education for parents on the impact of ACEs.
  • Tailored care for chronic conditions considering ACEs impact on hormonal and immune systems.

Public Health Perspective

  • Recognizing ACEs as a public health crisis is essential for effective solutions.
  • Historical public health successes (tobacco, lead poisoning, HIV-AIDS) can guide responses to ACEs.
  • Need for determination and commitment to address this issue nationwide.

Conclusion

  • ACEs affect many people, not just those in specific neighborhoods.
  • The need to face the issue of ACEs, as it is a collective challenge.
  • Emphasis on the importance of courage to acknowledge the reality of ACEs and the impact on health.
  • This issue is treatable and preventable.
