Is childhood sexual abuse a risk factor for bulimia nervosa?

OBJECTIVE: It is of considerable theoretical and clinical importance to assess whether childhood sexual abuse is a risk factor for the development of bulimia nervosa. The authors reviewed the scientific literature bearing on this issue. METHOD: Since prospective studies on this question have not been done, they assessed 1) controlled retrospective studies comparing the prevalence of childhood sexual abuse among bulimic and control groups, 2) uncontrolled retrospective studies of the prevalence of childhood sexual abuse in samples of 10 or more bulimic subjects, and 3) studies of the prevalence of childhood sexual abuse in the general population, which were chosen to match as closely as possible in methodology the available studies of bulimia nervosa (i.e., in geographic location, age and ethnicity of subjects, interview method, and criteria for defining childhood sexual abuse). RESULTS: Controlled studies generally did not find that bulimic patients show a significantly higher prevalence of childhood sexual abuse than control groups, especially when allowance is made for possible methodologic effects. Furthermore, neither controlled nor uncontrolled studies of bulimia nervosa found higher rates of childhood sexual abuse than were found in studies of the general population that used comparable methods. When it is taken into consideration that several methodologic factors might have exaggerated the rates of childhood sexual abuse among subjects with bulimia nervosa relative to rates in the general population, the absence of actual observed differences becomes particularly striking. CONCLUSIONS: Current evidence does support the hypothesis that childhood sexual abuse is a risk factor for bulimia nervosa.

Childhood sexual histories of women with somatization disorder.

The author interviewed 60 women with somatization disorder and 31 women with primary affective disorders who were matched for race, age at interview, and level of education to obtain their childhood sexual development histories. The two groups of women reported similar sexual experiences at similar ages, except that significantly more women with somatization disorder had been molested as children.

Past sexual victimization by females of male patients in an adolescent medicine clinic population.

In an adolescent medicine clinic with more than 1,000 patients during 1982-1984, 11 male adolescents reported a history of sexual molestation by females. This molestation had commonly involved acquaintances and was unlikely to have been accompanied by threats of violence or physical coercion. One-fourth of the victims of both male and female molesters described themselves as sexually dysfunctional, and eight of the victims of male molesters identified themselves as homosexual. Both groups experienced the molestation as highly traumatic.

Sexual abuse and bulimia nervosa: three integrated case control comparisons.

OBJECTIVE: This study had three aims: to determine whether sexual abuse increases the risk of developing bulimia nervosa, to see whether any increase in risk is specific to bulimia nervosa, and to determine whether patients referred for treatment of bulimia nervosa differ from a community group of subjects with bulimia nervosa with respect to their exposure to sexual abuse. METHOD: A case control design with individual matching was used. There were three related case control comparisons. Fifty community-based subjects with bulimia nervosa were compared with 100 community-based comparison subjects without an eating disorder, 50 community-based comparison subjects with other psychiatric disorders, and 50 patients (secondary referrals) with bulimia nervosa. An investigator-based interview was used to assess sexual abuse. RESULTS: Sexual abuse involving physical contact was reported by a minority of the community-based subjects with bulimia nervosa. It was more common among this group than among the normal comparison subjects. There was no difference between the community-based subjects with bulimia nervosa and either the subjects with general psychiatric disorders or the patients with bulimia nervosa. CONCLUSIONS: While the findings indicate that sexual abuse is a risk factor for the development of bulimia nervosa, it does not appear to be specific to bulimia nervosa nor is it relevant to most cases. Sexual abuse appears to be a risk factor for psychiatric disorder in general (including bulimia nervosa) among young adult women. There was no evidence that secondary referrals of bulimia nervosa are biased with respect to sexual abuse.

Childhood origins of self-destructive behavior.

OBJECTIVE: Clinical reports suggest that many adults who engage in self-destructive behavior have childhood histories of trauma and disrupted parental care. This study explored the relations between childhood trauma, disrupted attachment, and self-destruction, using both historical and prospective data. METHOD: Seventy-four subjects with personality disorders or bipolar II disorder were followed for an average of 4 years and monitored for self-destructive behavior such as suicide attempts, self-injury, and eating disorders. These behaviors were then correlated with independently obtained self-reports of childhood trauma, disruptions of parental care, and dissociative phenomena. RESULTS: Histories of childhood sexual and physical abuse were highly significant predictors of self-cutting and suicide attempts. During follow-up, the subjects with the most severe histories of separation and neglect and those with past sexual abuse continued being self-destructive. The nature of the trauma and the subjects' age at the time of the trauma affected the character and the severity of the self-destructive behavior. Cutting was also specifically related to dissociation. CONCLUSIONS: Childhood trauma contributes to the initiation of self-destructive behavior, but lack of secure attachments helps maintain it. Patients who repetitively attempt suicide or engage in chronic self-cutting are prone to react to current stresses as a return of childhood trauma, neglect, and abandonment. Experiences related to interpersonal safety, anger, and emotional needs may precipitate dissociative episodes and self-destructive behavior.

Dissociation in women with chronic pelvic pain.

OBJECTIVE: The authors' goal was to determine if women with chronic pelvic pain are significantly more likely to use dissociation as a coping mechanism than women without pain. METHOD: The subjects were recruited from women who attended a university women's clinic during a 1-month period. Twenty-two women who reported that they had at any time in their lives experienced pelvic pain nearly every day for a period of at least 6 months were included in the study, along with 21 randomly selected women without a history of chronic pelvic pain. The 43 women were given structured sexual assault interviews and completed psychological self-report measures. RESULTS: The women with chronic pain were significantly more likely to use dissociation as a coping mechanism, to show current psychological distress, to see themselves as medically disabled, to experience vocational and social decrements in function, and to amplify physical symptoms. They were also significantly more likely to have experienced severe childhood sexual abuse. In the total study group, women with a childhood history of sexual abuse had significantly higher scores on measures of psychological distress, somatization, and dissociation and viewed their physical health and functioning as more impaired. CONCLUSIONS: The authors discuss a model for the development of somatization, dissociation, and pain symptoms in victims of early sexual abuse.

Psychiatric correlates of incest in childhood.

OBJECTIVE: The purpose of the study was to describe more precisely the type of psychiatric illness associated with incest during childhood. METHOD: The Diagnostic Interview Schedule was administered to 52 adult women who had been victims of incest during childhood and to 23 age- and race-matched comparison subjects from local self-help agencies. RESULTS: The prevalence of 19 psychiatric disorders was higher in the incest group than base population rates. Rates of anxiety disorders (panic disorder, agoraphobia, social and simple phobia), major depression, and alcohol abuse and dependence were significantly higher in the incest group than in the comparison group. More severe types of incestuous abuse were associated with a higher risk for the development of psychiatric disorders. CONCLUSIONS: There was an association between incest and psychiatric disorders in this community-based treatment population. All patients, especially those who present with these specific psychiatric disorders, should be queried about childhood sexual abuse during the history.

Childhood sexual and physical abuse in adult patients with borderline personality disorder.

Experiences of abuse and neglect were assessed in 24 adults diagnosed as having borderline personality disorder according to the Diagnostic Interview for Borderline Patients and in 18 depressed control subjects without borderline disorder. Significantly more of the borderline patients than depressed patients reported childhood sexual abuse, abuse by more than one person, and both sexual and physical abuse. There were no between-group differences for rates of neglect or physical abuse without sexual abuse. A stepwise logistic regression revealed that derealization, diagnostic group, and chronic dysphoria were the best predictors of childhood sexual abuse in this group of patients.

Sexual and physical abuse histories and psychiatric symptoms among male psychiatric outpatients.

Of 125 consecutive male patients at an adult psychiatric outpatient clinic, 48% reported histories of sexual abuse and/or physical abuse. The mean scores on the global severity index of the SCL-90-R at the first visit were significantly higher for those who reported histories of abuse than for those who had no such history. Childhood abuse also was associated with high levels of psychiatric symptoms in these men.

Dissociation and childhood trauma in psychologically disturbed adolescents.

OBJECTIVE: To test the hypothesis that dissociation in adolescence is positively correlated with stress or abuse experienced earlier, the authors assessed dissociation in a heterogeneous group of disturbed adolescents and examined the relationship between the degree of dissociation and the degree of reported childhood stress, abuse, or trauma. METHOD: The subjects were 47 adolescents, 13-17 years old, who were institutionalized for periods of 1-13 weeks in a private mental hospital; 35 were girls and 12 were boys. Participants completed the Dissociative Experiences Scale and a child abuse and trauma questionnaire. The hospital records of 40 of the 47 adolescents were also available. RESULTS: Scores on the Dissociative Experiences Scale correlated significantly with self-reported physical abuse or punishment, sexual abuse, psychological abuse, neglect, and negative home atmosphere but not with abuse ratings made from hospital records. CONCLUSIONS: Together with the authors' previous work showing a relation between childhood stress and later dissociation in normal college students, these findings support the view that dissociation represents a reaction to early negative experience and places multiple personality disorder at the extreme end of a continuum of dissociative sequelae of childhood trauma. Researchers should continue to try to identify psychiatric patients with prominent dissociative characteristics or symptoms and attempt to correlate this phenomenology with negative earlier experiences.

Psychiatric morbidity in adult inpatients with childhood histories of sexual and physical abuse.

OBJECTIVE: To extend the knowledge on long-term effects of childhood abuse in psychiatric patients to a large sample, the authors explored childhood sexual and physical abuse in adult inpatients over 1,040 consecutive admissions. METHOD: The 947 patients were admitted to a tertiary-care military medical center. Each patient was interviewed, and abuse history, DSM-III-R diagnosis, and other characteristics were recorded. RESULTS: The prevalence of reported childhood abuse was 18% overall: 9% for sexual abuse (with or without physical abuse), 10% for physical abuse (with or without sexual abuse), and 3% for combined abuse. More female than male patients reported abuse. Alcohol use disorders were more common in victims of physical or combined abuse than in sexually abused or nonabused patients. Axis II diagnoses, particularly borderline personality disorder, were more frequent in abuse victims than in nonabused patients. Histories of drug and alcohol abuse were more common in patients reporting physical or combined abuse than in nonabused patients. Suicidality was also more frequent in abused than nonabused inpatients and was noted in 79% of the patients with histories of combined abuse. Combined abuse in women and physical abuse in men were associated with a family history of psychiatric illness, most commonly alcoholism in male relatives. CONCLUSIONS: These findings emphasize the need for greater attention to family dynamics, aggressive diagnosis and treatment of alcoholism within the family, and, especially, determination of patients' abuse histories, even if repeated questioning is necessary.

Impact of sexual abuse on children: a review and synthesis of recent empirical studies.

A review of 45 studies clearly demonstrated that sexually abused children had more symptoms than nonabused children, with abuse accounting for 15-45% of the variance. Fears, posttraumatic stress disorder, behavior problems, sexualized behaviors, and poor self-esteem occurred most frequently among a long list of symptoms noted, but no one symptom characterized a majority of sexually abused children. Some symptoms were specific to certain ages, and approximately one third of victims had no symptoms. Penetration, the duration and frequency of the abuse, force, the relationship of the perpetrator to the child, and maternal support affected the degree of symptomatology. About two thirds of the victimized children showed recovery during the first 12-18 months. The findings suggest the absence of any specific syndrome in children who have been sexually abused and no single traumatizing process.

Altered pain perception and psychosocial features among women with gastrointestinal disorders and history of abuse: a preliminary model.

OBJECTIVES: To evaluate the relationships between sexual/physical abuse, pain perception, environmental events, coping strategies, and psychiatric morbidity in a sample of female patients with painful gastrointestinal disorders. PATIENTS: Fifty paid volunteers from a tertiary care center including 13 patients with gastroesophageal reflux disease (GERD), 26 with noncardiac chest pain (NCCP), and 11 with irritable bowel syndrome (IBS). MEASUREMENTS: (1) Sexual and physical abuse interview questions; (2) Structured psychiatric interview; (3) Self-report questionnaires: demographics, clinical pain measurement, Millon Behavioral Health Inventory, Hassles and Uplifts Scales, Sickness Impact Profile, Life Experiences Survey, Pain Beliefs and Perceptions Inventory, and Coping Strategies Questionnaire; (4) Pain Perception and Sensory Decision Theory tasks. RESULTS: Fifty-six percent of the sample reported a history of sexual/physical abuse. Abuse was significantly more prevalent among patients with GERD (92%) and IBS (82%) compared with those with NCCP (27%). Abused patients, relative to nonabused patients, had significantly lower pain threshold levels in response to finger pressure stimuli and significantly lower cognitive standards for judging stimuli as noxious. Abused patients reported significantly higher levels of functional disability and a significantly greater number of psychiatric disorders, minor daily hassles, and pain syndromes unrelated to gastrointestinal disorders. In addition, abused patients more frequently blamed themselves for their pain and reported significantly greater use of maladaptive pain coping strategies than nonabused patients. CONCLUSION: These data suggest that the relationships between abuse, disability, multiple pain syndromes, and health care seeking behavior are mediated by abnormal pain perception, psychiatric disorders, disruption of physical function, and environmental stressors.

Childhood sexual abuse reported by facilitated communication.

Facilitated communication remains an unproven and controversial strategy for nonspeaking children with developmental disabilities. It is possible that the process may be influenced by the facilitator. The evaluation of alleged sexual abuse reported by FC must include a full psychosocial history, complete physical examination for evidence of abuse, and the assessment of the child's communicative competence. The demonstration of communicative competence requires a strategy similar to that utilized with Carla. The successful documentation of the child's communication of general information should precede the pursuit of specific abuse issues.

Behavior, family function, school performance, and predictors of persistent disturbance in sexually abused children.

OBJECTIVE: Although sexual abuse is widely considered to have severe sequelae, most studies of children's status after sexual abuse have had major limitations, including retrospective design, small sample sizes, selective enrollment of subjects, no comparison groups, and lack of information about potentially confounding characteristics of studied children. The aim of this study was to clarify the impact of sexual abuse on children's psychological well-being. METHODS: We prospectively studied 154 children who were brought to urban, university-affiliated hospitals for assessment of recently disclosed sexual abuse and compared them with a control group of 53 demographically similar children not known to have been sexually abused. RESULTS: In comparison with the control children, fewer of the sexually abused children had health insurance and more had received psychiatric care unrelated to the sexual abuse. Most initial ratings of behavior, maternal psychiatric status, family function, and school performance were less favorable among the sexually abused than among the control children (P < .05). At follow-up 6 months later, the psychiatric status of the mothers of the abused children apparently improved, but the children's difficulties largely persisted. Baseline characteristics of the abused children significantly or suggestively associated with persisting problematic behavior were older age (P = .04), lower maternal educational attainment (P = .06), poorer maternal psychiatric status (P = .04) and lower family integration (P < .001). These four factors accounted for 31% of the variance in the children's behavior at 6-month follow-up (P < .001). Unexpectedly, characteristics of the children's sexual abuse experiences did not predict their later behavioral status. CONCLUSIONS: These findings suggest that preexisting, long-standing adverse psychosocial circumstances may contribute importantly to persistently problematic behavior and school performance among sexually abused children. The findings also suggest that it is children's preexisting psychosocial circumstances, rather than the abuse, that determine, at least in part, the nature of their functional outcomes.

Perianal injuries resulting from sexual abuse: a longitudinal study.

Four children who incurred perianal injuries as a result of a sexual assault were followed on a longitudinal basis to document the anatomical changes that ensued. The subjects, whose ages ranged from 4 to 8 years, were followed from 1 week to 14 months. They were examined in both supine and prone knee-chest positions and a 35-mm camera mounted on a colposcope was used to record their injuries. At the time of the initial examination, there were a variety of findings including erythema of the tissues, edema of the skin folds, localized venous engorgement, dilation of the external anal sphincter, and lacerations of different depths. Superficial lacerations reepithelized within 1 to 11 days. The second-degree wounds in two of the children were healed by the 1- and 5-week return visits, leaving narrow bands of scar tissue. In the two subjects who were followed the longest, signs of both a second-degree laceration and a surgically repaired third-degree injury had virtually disappeared by 12 to 14 months after the assaults. The wounds in one subject, infected with a herpes simplex type 2 virus, remained erythematous for a longer period of time than did similar injuries in the other children. A skin tag created by the avulsion of the tissues in one subject persisted, although it became less obvious as it retracted into the redundant folds of the perianal tissues over time.

Transmission of human genital papillomavirus disease: comparison of data from adults and children.

A substantial body of evidence has demonstrated that the primary means of transmission of genital warts in sexually active adults is through sexual contact. However, the epidemiology and social significance of anal-genital warts in prepubertal children is controversial. Debate continues regarding the frequency with which these lesions have resulted from sexual abuse or transmission by other means. An accurate understanding of the dominant means of transmission of anal-genital warts in children is of particular importance because that understanding influences the extent to which child protective services may become involved following a diagnosis. This paper reviews the evolution of the data on the means of transmission of human papilloma virus disease of the genital tract of adults and compares those data with the information available concerning the transmission of anal-genital human papillomavirus-related disease in children. Methods for the diagnosis of child sexual abuse that have developed in the past decade form one of the bases for the evaluation of studies of the transmission of anal-genital human papillomavirus-related diseases to children.

Situational and sociodemographic characteristics of children infected with human immunodeficiency virus from pediatric sexual abuse.

This study assessed the situational and sociodemographic characteristics of children infected with human immunodeficiency virus (HIV) from pediatric sexual abuse. A letter of inquiry was sent to 2147 professionals across health and social service disciplines involved with child abuse assessment, treatment, and prevention. Respondents working in programs where HIV antibody testing of abuse victims occurs and who had identified HIV infection in one or more abused children were sent a survey to assess the demographics of victims, the family/living situation where abuse occurred, alternative risks for HIV infection, bases for diagnosis of sexual abuse and for HIV antibody testing, and profiles of the perpetrator and type of abuse. Of 5622 estimated HIV antibody tests conducted during 113,198 sex abuse assessments, 28 children were infected with HIV and lacked any alternative transmission route to that of sexual abuse. A total of 41 HIV-infected children with a history of sexual abuse were identified. Thirteen cases had alternative risk factors and were excluded from analysis. Sixty-four percent of the 28 victims with sexual abuse as the sole risk factor were female and 71% were African-American. The mean age was 9 years. Coinfection with another sexually transmitted disease (STD) occurred in 9 (33%) cases. Sexual abuse was diagnosed on the basis of a victim disclosure in 21 (75%) cases. The basis for HIV antibody testing was physical findings suggestive of HIV infection in 9 (32%) cases, HIV-seropositive or high-risk perpetrator in 6 (21%) and 2 (7%) cases, respectively, and the presence of another STD in the victim in 4 (14%) cases. Perpetrators were a child's parent in 10 (42%) cases and another relative in 6 (25%) cases.(ABSTRACT TRUNCATED AT 250 WORDS)

Health risk behaviors and medical sequelae of childhood sexual abuse.

The relationship between childhood sexual abuse and subsequent health risk behaviors and medical problems was examined in 511 women who had used a family practice clinic in a rural midwestern community during a 2-year period (1988 and 1989). These women completed a questionnaire that assessed various health risk behaviors--smoking, drinking, drug abuse, number of sexual partners, and age at first intercourse--and a medical symptom checklist that assessed 38 medical problems related to major systems of body function, the somatization scale from the SCL-90, a screen for sexual abuse, and a brief measure of social support. The results indicated that sexually abused women, who represented 22.1% of the sample, reported significantly more medical problems, greater levels of somatization, and more health risk behaviors than did the nonabused women. More severe abuse (for example, penetration or multiple abusers) correlated with more severe problems. Extent of social support correlated inversely with the number of gynecologic problems reported in the sexually abused group. Fewer than 2% of the sexually abused women had discussed the abuse with a physician. To identify and assist victims of sexual abuse, physicians should become experienced with nonthreatening methods of eliciting such information when the medical history is obtained.

Prognosis of human immunodeficiency virus infection in children and adolescents.

The prognosis of 111 children and adolescents (from 2.5 months to 19.5 years of age) infected with human immunodeficiency virus (HIV) was assessed by survival analysis based on risk factors and clinical status. Risk factors included: maternal HIV infection 93; transfusion 12; both maternal HIV infection and transfusion 2; sexual abuse 1; and intravenous drug use and/or sexual activity 3. Children with perinatal infection survived from 2.5 months to 10.25 years (median, 1.87 years) and had inapparent infection from 6 weeks to 7.3 years (median, 0.75 years). Children who acquired HIV infection via transfusion had inapparent infection from 4 months to 5.7 years (median, 3.6 years). Actuarial survival following infection was not significantly different from maternally and transfusion-acquired infection; however, survival from infection was longer for children infected by transfusion beyond 2 years of age (mean, 7.5 years) than for children infected perinatally (mean, 5.6 years). The case-fatality ratio was 32%, with 25% of subjects succumbing within 1 year of developing an HIV-associated illness. Opportunistic infection was the most common acquired immunodeficiency syndrome-defining illness and the cause of death in 22 of the 35 children who died. Pneumocystis carinii and fungal pneumonias had the worst prognosis. Cryptosporidiosis and other opportunistic infections had a better prognosis. Because of difficulties in case finding, diagnosis of infection and variable survival of HIV-infected children, arge longitudinal studies and pooling of data among centers will be necessary to have an accurate understanding of the prognosis of individual clinical syndromes.(ABSTRACT TRUNCATED AT 250 WORDS)
