They can have lasting, cumulative effects on mental and physical health and overall well-being far into adulthood. Here's a look at traumatic experiences in childood, their effects, and some coping strategies to try. What to Know About Traumatic Shock Types of Adverse Childhood Experiences (ACEs) Examples of ACEs include: Physical or emotional abuse Abandonment or neglect Loss of a family member to suicide Substance abuse or alcoholism in the household A mentally ill parent An incarcerated parent Parental divorce or separation Early Research In 1995, researchers at the Centers for Disease Control and Prevention (CDC), in conjunction with Kaiser Permanente, became the first to explore the consequences of childhood trauma on adult well-being. They interviewed roughly 17,000 people about various traumatic childhood experiences such as abuse, violence, neglect, and abandonment. An estimated 66% of respondents said they'd experienced at least one ACE; 20% had experienced three ACEs. The researchers noted associations between ACEs and physical health issues such as heart disease and cancer even years later. Risk Factors ACEs don’t happen randomly. Many factors make a child more likely to experience an ACE, including: A low-income or low-education familyHigh levels of family or economic stressA family who is not close and does not speak openly about feelingsParents who used spanking or corporal punishmentParents who had been abused or neglectedA community with high rates of violence or substance abuseAn economically disadvantaged communityA community with few resources for youth Incidence About 64% of U.S. adults said they'd experienced one or more types of ACE by the time they'd reached 18—and 17.3% had experienced four or more. Racial disparities in the data are prevalent. About 61% of Black children, 51% of Hispanic children, 23% of Asian children, and 40% of white children had experienced an ACE. Impact All children have difficult experiences at times, but they generally can learn from their experiences and become stronger with the proper tools. ACEs, however, are more difficult to overcome and can leave lasting scars, especially if the child lacks support. ACEs can cause “toxic stress,” which floods the body enough to cause changes to the metabolic, immune, cardiovascular, brain, and nervous systems. Their effects are cumulative: The more ACEs a child experiences, the greater impact it can have on mental and physical health. ACEs and toxic stress may be associated with: Difficulty forming close relationships with othersTrouble keeping a jobDifficulty with financesDepressionGreater likelihood of being involved in violenceEarly, unplanned pregnanciesGreater likelihood of incarcerationHigher levels of unemploymentExposure of offspring to ACEsHigher risk of alcohol or substance abuseGreater risk of suicide attemptsHealth issues such as heart disease, cancer, lung disease, and liver disease Mental Health Effects of Different Types of Abuse Prevention According to the CDC, preventing ACEs in children requires a multipronged group effort. Here are some of the top ACE prevention strategies: Policymakers can work toward reducing financial, food, and housing insecurity. Employers can adopt family-friendly policies and offer family leave. Communities and policymakers can promote antiviolence campaigns and education. Professionals who work with families can teach positive parenting skills and socio-emotional learning. Policymakers can expand childcare, preschool, and early childhood education options. Communities can prioritize youth services, mentorships, and substance abuse recovery programs. Substance Use vs. Substance Abuse: What Are the Differences? Coping With ACEs Remember that ACEs commonly have effects for years and even decades afterward—and there are proven strategies to try as you work through them. See a trauma-focused therapist or social worker, who can help with ACE-related anxiety, depression, and (PTSD).Speak with a healthcare provider if you're feeling physical effects that you suspect might be linked to an ACE.Learn meditation techniques and breathing exercises.Add some physical activity to your day.Release some of your feelings through journaling.Join a support group specific to your ACE (for example, abandonment, abuse, etc.).
