Physical health impacts of childhood abuse and household dysfunction in adulthood
The oft-replicated Centre for Disease Control and Prevention's Adverse Childhood Experience (ACE) Study is one of the largest investigations of childhood abuse and neglect, and its impact on later-life health and well-being.
The study proved that adverse childhood experiences have a dose-response relationship with many physical-health problems; and a strong, graded relationship to numerous health, social, and behavioural problems throughout the entire lifespan. These were not usually thought of as related to childhood abuse or neglect, and included problems such as heart disease, cancer, chronic pain, emphysema, diabetes, chronic lung disease, sexual health problems, sexually transmitted infections, depression, eating disorders, major dental problems, self-mutilation, learning disorders, alcoholism, drug abuse, domestic violence, teenage pregnancies, homelessness, suicide, and more.
