Relationship of childhood abuse and household dysfunction to many of the leading causes of death in adults. The Adverse Childhood Experiences (ACE) Study.

BACKGROUND The relationship of health risk behavior and disease in adulthood to the breadth of exposure to childhood emotional, physical, or sexual abuse, and household dysfunction during childhood has not previously been described. METHODS A questionnaire about adverse childhood experiences was mailed to 13,494 adults who had completed a standardized medical evaluation at a large HMO; 9,508 (70.5%) responded. Seven categories of adverse childhood experiences were studied: psychological, physical, or sexual abuse; violence against mother; or living with household members who were substance abusers, mentally ill or suicidal, or ever imprisoned. The number of categories of these adverse childhood experiences was then compared to measures of adult risk behavior, health status, and disease. Logistic regression was used to adjust for effects of demographic factors on the association between the cumulative number of categories of childhood exposures (range: 0-7) and risk factors for the leading causes of death in adult life. RESULTS More than half of respondents reported at least one, and one-fourth reported > or = 2 categories of childhood exposures. We found a graded relationship between the number of categories of childhood exposure and each of the adult health risk behaviors and diseases that were studied (P < .001). Persons who had experienced four or more categories of childhood exposure, compared to those who had experienced none, had 4- to 12-fold increased health risks for alcoholism, drug abuse, depression, and suicide attempt; a 2- to 4-fold increase in smoking, poor self-rated health, > or = 50 sexual intercourse partners, and sexually transmitted disease; and 1.4- to 1.6-fold increase in physical inactivity and severe obesity. The number of categories of adverse childhood exposures showed a graded relationship to the presence of adult diseases including ischemic heart disease, cancer, chronic lung disease, skeletal fractures, and liver disease. The seven categories of adverse childhood experiences were strongly interrelated and persons with multiple categories of childhood exposure were likely to have multiple health risk factors later in life. CONCLUSIONS We found a strong graded relationship between the breadth of exposure to abuse or household dysfunction during childhood and multiple risk factors for several of the leading causes of death in adults.

Adverse childhood experiences and personal alcohol abuse as an adult.

Adult alcohol abuse has been linked to childhood abuse and family dysfunction. However, little information is available about the contribution of multiple adverse childhood experiences (ACEs) in combination with parental alcohol abuse, to the risk of later alcohol abuse. A questionnaire about childhood abuse, parental alcoholism and family dysfunction while growing up was completed by adult HMO members in order to retrospectively assess the independent relationship of eight ACEs to the risk of adult alcohol abuse. The number of ACEs was used in stratified logistic regression models to assess their impact on several adult alcohol problems in the presence or absence of parental alcoholism. Each of the eight individual ACEs was associated with a higher risk alcohol abuse as an adult. Compared to persons with no ACEs, the risk of heavy drinking, self-reported alcoholism, and marrying an alcoholic were increased twofold to fourfold by the presence of multiple ACEs, regardless of parental alcoholism. Prevention of ACEs and treatment of persons affected by them may reduce the occurrence of adult alcohol problems.

Adverse childhood experiences and the risk of premature mortality.

BACKGROUND Strong, graded relationships between exposure to childhood traumatic stressors and numerous negative health behaviors and outcomes, healthcare utilization, and overall health status inspired the question of whether these adverse childhood experiences (ACEs) are associated with premature death during adulthood. PURPOSE This study aims to determine whether ACEs are associated with an increased risk of premature death during adulthood. METHODS Baseline survey data on health behaviors, health status, and exposure to ACEs were collected from 17,337 adults aged >18 years during 1995-1997. The ACEs included abuse (emotional, physical, sexual); witnessing domestic violence; parental separation or divorce; and growing up in a household where members were mentally ill, substance abusers, or sent to prison. The ACE score (an integer count of the eight categories of ACEs) was used as a measure of cumulative exposure to traumatic stress during childhood. Deaths were identified during follow-up assessments (between baseline appointment date and December 31, 2006) using mortality records obtained from a search of the National Death Index. Expected years of life lost (YLL) and years of potential life lost (YPLL) were computed using standard methods. The relative risk of death from all causes at age < or =65 years and at age < or =75 years was estimated across the number of categories of ACEs using multivariable-adjusted Cox proportional hazards regression. Analysis was conducted during January-February 2009. RESULTS Overall, 1539 people died during follow-up; the crude death rate was 91.0 per 1000; the age-adjusted rate was 54.7 per 1000. People with six or more ACEs died nearly 20 years earlier on average than those without ACEs (60.6 years, 95% CI=56.2, 65.1, vs 79.1 years, 95% CI=78.4, 79.9). Average YLL per death was nearly three times greater among people with six or more ACEs (25.2 years) than those without ACEs (9.2 years). Roughly one third (n=526) of those who died during follow-up were aged < or =75 years at the time of death, accounting for 4792 YPLL. After multivariable adjustment, adults with six or more ACEs were 1.7 (95% CI=1.06, 2.83) times more likely to die when aged < or =75 years and 2.4 (95% CI=1.30, 4.39) times more likely to die when aged < or =65 years. CONCLUSIONS ACEs are associated with an increased risk of premature death, although a graded increase in the risk of premature death was not observed across the number of categories of ACEs. The increase in risk was only partly explained by documented ACE-related health and social problems, suggesting other possible mechanisms by which ACEs may contribute to premature death.

Growing up with Parental Alcohol Abuse: Exposure to Childhood Abuse, Neglect, and Household Dysfunction.

OBJECTIVE This study is a detailed examination of the association between parental alcohol abuse (mother only, father only, or both parents) and multiple forms of childhood abuse, neglect, and other household dysfunction, known as adverse childhood experiences (ACEs). METHOD A questionnaire about ACEs including child abuse, neglect, household dysfunction, and exposure to parental alcohol abuse was completed by 8629 adult HMO members to retrospectively assess the relationship of growing up with parental alcohol abuse to 10 ACEs and multiple ACEs (ACE score). RESULTS Compared to persons who grew up with no parental alcohol abuse, the adjusted odds ratio for each category of ACE was approximately 2 to 13 times higher if either the mother, father, or both parents abused alcohol (p < 0.05). For example, the likelihood of having a battered mother was increased 13-fold for men who grew up with both parents who abused alcohol (OR, 12.7; 95% CI: 8.4-19.1). For almost every ACE, those who grew up with both an alcohol-abusing mother and father had the highest likelihood of ACEs. The mean number of ACEs for persons with no parental alcohol abuse, father only, mother only, or both parents was 1.4, 2.6, 3.2, and 3.8, respectively (p < .001). CONCLUSION Although the retrospective reporting of these experiences cannot establish a causal association with certainty, exposure to parental alcohol abuse is highly associated with experiencing adverse childhood experiences. Improved coordination of adult and pediatric health care along with related social and substance abuse services may lead to earlier recognition, treatment, and prevention of both adult alcohol abuse and adverse childhood experiences, reducing the negative sequelae of ACEs in adolescents and adults.

Exposure to abuse, neglect, and household dysfunction among adults who witnessed intimate partner violence as children: implications for health and social services.

Intimate partner violence (IPV) damages a woman’s physical and mental well-being, and indicates that her children are likely to experience abuse, neglect and other traumatic experiences. Adult HMO members completed a questionnaire about adverse childhood experiences (ACEs) including childhood abuse, neglect, and household dysfunction. We used their responses to retrospectively assess the relationship between witnessing intimate partner violence and experiencing any of the 9 ACEs and multiple ACEs (ACE score). Compared to persons who grew up with no domestic violence, the adjusted odds ratio for any individual ACE was approximately two to six times higher if IPV occurred (p < 0.05). There was a powerful graded increase in the prevalence of every category of ACE as the frequency of witnessing IPV increased. In addition, the total number of ACEs was increased dramatically for persons who had witnessed IPV during childhood. There was a positive graded risk for self-reported alcoholism, illicit drug use, IV drug use and depressed affect as the frequency of witnessing IPV increased. Identification of victims of IPV must include screening of their children for abuse, neglect and other types of adverse exposures, as well as recognition that substance abuse and depressed affect are likely consequences of witnessing IPV. Finally, this data strongly suggest that future studies, which focus on the effect of witnessing IPV on long-term health outcomes, may need to take into consideration the co-occurrence of multiple ACEs, which can also affect these outcomes.

Adverse childhood experiences are associated with the risk of lung cancer: a prospective cohort study

BackgroundStrong relationships between exposure to childhood traumatic stressors and smoking behaviours inspire the question whether these adverse childhood experiences (ACEs) are associated with an increased risk of lung cancer during adulthood.MethodsBaseline survey data on health behaviours, health status and exposure to adverse childhood experiences (ACEs) were collected from 17,337 adults during 1995-1997. ACEs included abuse (emotional, physical, sexual), witnessing domestic violence, parental separation or divorce, or growing up in a household where members with mentally ill, substance abusers, or sent to prison. We used the ACE score (an integer count of the 8 categories of ACEs) as a measure of cumulative exposure to traumatic stress during childhood. Two methods of case ascertainment were used to identify incident lung cancer through 2005 follow-up: 1) hospital discharge records and 2) mortality records obtained from the National Death Index.ResultsThe ACE score showed a graded relationship to smoking behaviors. We identified 64 cases of lung cancer through hospital discharge records (age-standardized risk = 201 × 100,000-1 population) and 111 cases of lung cancer through mortality records (age-standardized mortality rate = 31.1 × 100,000-1 person-years). The ACE score also showed a graded relationship to the incidence of lung cancer for cases identified through hospital discharge (P = 0.0004), mortality (P = 0.025), and both methods combined (P = 0.001). Compared to persons without ACEs, the risk of lung cancer for those with ≥ 6 ACEs was increased approximately 3-fold (hospital records: RR = 3.18, 95%CI = 0.71-14.15; mortality records: RR = 3.55, 95%CI = 1.25-10.09; hospital or mortality records: RR = 2.70, 95%CI = 0.94-7.72). After a priori consideration of a causal pathway (i.e., ACEs → smoking → lung cancer), risk ratios were attenuated toward the null, although not completely. For lung cancer identified through hospital or mortality records, persons with ≥ 6 ACEs were roughly 13 years younger on average at presentation than those without ACEs.ConclusionsAdverse childhood experiences may be associated with an increased risk of lung cancer, particularly premature death from lung cancer. The increase in risk may only be partly explained by smoking suggesting other possible mechanisms by which ACEs may contribute to the occurrence of lung cancer.

Adverse childhood experiences and risk of paternity in teen pregnancy.

OBJECTIVE Few studies have investigated risk factors that predispose males to be involved in teen pregnancies. To provide new information on such factors, we examined the relationships of eight common adverse childhood experiences to a males risk of impregnating a teenager. METHODS We conducted a retrospective cohort study using questionnaire responses from 7399 men who visited a primary care clinic of a large health maintenance organization in California. Data included age of the youngest female ever impregnated; the mans own age at the time; his history of childhood emotional, physical, or sexual abuse; having a battered mother; parental separation or divorce; and having household members who were substance abusers, mentally ill, or criminals. Odds ratios (ORs) for the risk of involvement in a teen pregnancy were adjusted for age, race, and education. RESULTS At least one adverse childhood experience was reported by 63% of participants, and 34% had at least two adverse childhood experiences; 19% of men had been involved in a teen pregnancy. Each adverse childhood experience was positively associated with impregnating a teenager, with ORs ranging from 1.2 (sexual abuse) to 1.8 (criminal in home). We found strong graded relationships (P < .001) between the number of adverse childhood experiences and the risk of involvement in a teen pregnancy for each of four birth cohorts during the last century. Compared with males with no adverse childhood experiences, a male with at least five adverse childhood experiences had an OR of 2.6 (95% confidence interval [CI] 2.0, 3.4) for impregnating a teenager. The magnitude of the ORs for the adverse childhood experiences was reduced 64–100% by adjustment for potential intermediate variables (age at first intercourse, number of sexual partners, having a sexually transmitted disease, and alcohol or drug abuse) that also exhibited a strong graded relationship to adverse childhood experiences. CONCLUSION Adverse childhood experiences have an important relationship to male involvement in teen pregnancy. This relationship has persisted throughout four successive birth cohorts dating back to 1900–1929, suggesting that the effects of adverse childhood experiences transcend changing sexual mores and contraceptive methods. Efforts to prevent teen pregnancy will likely benefit from preventing adverse childhood experiences and their associated effects on male behaviors that might mediate the increased risk of teen pregnancy.

Bias assessment for child abuse survey:: Factors affecting probability of response to a survey about childhood abuse

A device and method for reconstructing a vector wave and its source direction by measuring the amplitudes of the vector wave in directions chosen according to a necessary and sufficient condition that ensures that the measured amplitudes contain enough information to provide a unique set of relative phases among the sinusoidally time-varying components of the vector wave. Together with the amplitudes, these relative phases are processed by a microprocessor to yield the polarization characteristics of the vector wave and the direction of its source.

Adverse childhood experiences and smoking persistence in adults with smoking-related symptoms and illness.

OBJECTIVES Little is known about why people continue to smoke after learning that they have diseases and conditions that contraindicate smoking. Using data from the Adverse Childhood Experiences (ACE) Study, we examined the relation between ACEs and smoking behavior when smoking-related illnesses or conditions are present, both with and without depression as a mediator. METHODS Participants were more than 17,000 adult HMO members who retrospectively reported on eight categories of ACEs (emotional, physical, and sexual abuse; witnessing interparental violence; parental divorce; and growing up with a substance-abusing, mentally ill, or incarcerated household member). The number of maltreatment categories was summed to form an ordinal variable called the ACE Score. We measured current smoking, conditions that contraindicate smoking (heart disease, chronic lung disease, and diabetes), and symptoms of these illnesses (chronic bronchitis, chronic cough, and shortness of breath). Logistic regression models compared the ACE Score of smokers with smoking-related illnesses to participants who reported these illnesses but were not current smokers (n = 7483). RESULTS Significant dose-response relations between the ACE Score and smoking persistence were found (odds ratio = 1.69; confidence interval = 1.34-2.13 for participants with ≥4 ACEs). Depression was a significant independent predictor of smoking persistence as well as a mediator. Depression only slightly attenuated the relation between the ACE Score and persistent smoking, however. CONCLUSION Medical practitioners should consider the maltreatment history and depression status of their patients when a smoking-related diagnosis fails to elicit smoking cessation. Programs should be developed that better address the underlying motivations for continuing to smoke in the face of health problems that contraindicate smoking.
