Child abuse and mental health among adolescents in dependent care.

Do adolescents in dependent care who have been abused or neglected demonstrate more mental health problems than their nonabused peers? This study examined relationships of child abuse, depression, and self-esteem among 82 adolescents (mean age 14.5 years, 52% male, 82.9% white) living in a dependent care facility. Of these, 32 adolescents were victims of child abuse or neglect. Upon admission, 54 adolescents were identified as depressed on the Beck Depression Inventory. Initial scores on the depression and self-esteem instruments did not differ by age, race, or history of maltreatment, though trends among subtypes of abuse were identified. Females had significantly lower self-esteem and tended toward more depression. Repeat evaluation 6 months after admission revealed significant improvement in both depression and self-esteem scores for the entire sample. As a group, however, the maltreated adolescents did not demonstrate significant improvement in depression, and a history of neglect was associated with less improvement. Depression in this dependent care sample was common, however, we did not identify the maltreated adolescents as having significantly more problems with self-esteem or depression. For some adolescents, dependent care may be an appropriate and helpful alternative.

Factors associated with condom use among sexually active female adolescents.

A health belief model of condom use was used to identify factors associated with condom use in 390 sexually active female adolescents, aged 12 through 19 years, recruited at the time of a visit for reproductive health care. Fifty-six percent were white and the remainder black. Nineteen percent had genitourinary infections with Chlamydia trachomatis. Forty-six percent reported having had more than one sexual partner in the preceding year. Reported condom use for at least one specific reason (prevention of pregnancy, sexually transmitted disease, or acquired immunodeficiency syndrome) increased as behavioral, emotional, and sexually transmitted disease risk decreased, and as cognitive maturity and positive condom attitudes increased. Although uses of condoms to prevent pregnancy, sexually transmitted disease, and acquired immunodeficiency syndrome were positively intercorrelated, each made a contribution to explaining condom use at most recent coitus (odds ratios 2.95, 3.96, and 2.81, respectively). After statistical adjustment for the reported reasons for previous condom use, behavioral risk was the only additional factor associated with condom use at the most recent sexual encounter; women who participated in more risk behaviors (substance and alcohol use and minor delinquency) were less likely to have used a condom (odds ratio 0.61). Knowledge about sexually transmitted disease and acquired immunodeficiency syndrome, and concurrent use of contraceptive pills, were not related to condom practices. The data suggest that adolescents' perceptions about condoms, including the individual functions of condoms for contraception and for prevention of sexually transmitted disease, may be important in determining their use. Engaging in unprotected intercourse may be part of a larger behavioral domain that includes other unhealthy behaviors.

Relationships of somatic symptoms to behavioral and emotional risk in young adolescents.

Junior high students (n = 1508) from a midwestern community completed a health behavioral questionnaire that asked the frequency of headache and abdominal pain and of a number of behavioral and emotional risk indicators. Headache (24%) and abdominal pain (13%) were frequently reported among these young adolescents, particularly among girls. Those reporting frequent somatic complaints also reported significantly more behavioral and emotional symptoms indicative of risk (p less than 0.001). Further, the interaction between somatic complaint and gender significantly affected risk status (p less than 0.01). This interaction was greater with behavioral risk: boys with both abdominal pain and headaches reported higher behavioral risk than all other groups (p less than 0.0001). Somatic symptoms continued to account for a significant amount of variance in behavioral risk after the effects of emotional risk and age were removed. This suggests that behavioral risk and emotional risk are independently associated with somatic complaints. The evaluation of persistent somatic complaints in adolescents, particularly in boys with abdominal symptoms, should include careful examination of emotional risk factors and other health-endangering behaviors such as substance use, early sexual activity, and delinquency.

Abdominal Pain

Premature sexual activity as an indicator of psychosocial risk.

Although unprotected premature sexual activity is associated with well-defined biologic risks of sexually transmitted disease and pregnancy, the concomitant psychosocial risks are less well documented. The strength of association (odds ratio) of coital status with other risk behaviors and feelings was examined in 1504 junior high school students. Among the 12 through 16-year-old students, 63% of the boys and 36% of the girls were nonvirginal (had had intercourse at least once). The proportion of sexually experienced boys and girls increased with age. Nonvirginal boys and girls were significantly (P less than .001) more likely than their virginal cohorts to engage in other activities considered risky. The odds ratios for nonvirginal youth ranged from 3.5 for girls having used drugs other than alcohol or marijuana, to 10.4 for girls having used marijuana. Nonvirginal boys and girls were also at significantly greater risk for engaging in minor delinquent acts and having school problems. Nonvirginal girls (but not boys) were 6.3 times more likely to report having attempted suicide. The strength of associations with feelings was weaker. Nonvirginal girls were at slightly greater risk for reporting feeling lonely, feeling upset, and having difficulty sleeping. A significant proportion of the students reported sexual experience and ever use of alcohol or marijuana (45% of boys, 27% of girls). There were strong age effects so that by age 15 years, 63% of the boys and 50% of the girls reported experience with both activities. The data suggest that early sexual experience among adolescents is associated with other potentially health-endangering behaviors and that the syndrome of problem behaviors is important in this age group.

Behavioral risk, emotional risk, and child abuse among adolescents in a nonclinical setting.

In this replication study of adolescents in a nonclinical setting, the prevalence of reported problem behaviors, emotions, and abuse is evaluated, and the impact of abuse on multivariate emotional and behavioral risk is assessed. A total of 3998 students (69%) in a rural midwestern community in grades 7 to 12 participated in the study. Almost 20% of the students reported some form of physical and/or sexual abuse, with more girls than boys reporting sexual abuse (chi 2 = 48.5, P less than .001). Some problem behaviors (alcohol use) and emotions (trouble sleeping, difficulty with anger) were common among all adolescents and some were strongly associated with a history of abuse (especially, considering or attempting suicide, running away, laxative use, and vomiting to lose weight). Higher emotional and behavioral risk scores among abused students were confirmed. The effects of physical and sexual abuse on risk scores were independent and additive; no interaction was observed. An interaction of gender and sexual abuse on problem behavior was observed, with problem behavior being significantly greater among sexually abused boys. The results confirm increased risk of problem behaviors and negative feelings among abused adolescents when compared with nonabused peers, and better define influences of gender and abuse type on emotional and behavioral risks.

Reported sexual behaviors and self-esteem among young adolescents.

Six hundred seventy-seven adolescents in grades 7 through 9 of a blue-collar, midwestern junior high school responded to a survey of sexual behavior and self-esteem. The focus of this study was on the relationship between sexual experience and self-esteem. Fifty-five percent of the students reported having had at least one coital experience; 7% reported having intercourse about once a week. The proportion of sexually experienced adolescents increased with age; 28% of 12-year-olds, 52.7% of 13-year-olds, 60.1% of 14-year-olds, 73.6% of 15-year-olds, and 90% of 16-year-olds reported having intercourse on at least one occasion. More boys of all ages were sexually active than girls. Six percent of students had had, or were suspicious of having had, a sexually transmitted disease; 7.8% were involved in a pregnancy. The average of the self-esteem scores for girls was significantly lower than the average for boys. There was an interaction effect between gender and coital history for self-esteem. Girls who reported having had intercourse had lower self-esteem scores than those who did not. On the other hand, self-esteem of sexually experienced and inexperienced boys did not differ, nor did self-esteem of virginal boys and girls. Boys and girls with a history of sexually transmitted diseases had lower self-esteem than all others. Pregnancy, on the other hand, did not seem to affect self-esteem of the sexually experienced adolescents. This cross-sectional study does not permit determination of whether the lower average self-esteem among certain girls was antecedent to or a consequence of sexual experience.

Clinical evaluation of computer-assisted self-monitoring of blood glucose system.

The Glucometer M Diabetes Management System includes a glucose-reflectance meter with memory that can interface with a microcomputer for data manipulation and analysis. We evaluated the system in a short-term randomized control trial to determine its impact on metabolic control, self-monitoring of blood glucose (SMBG) testing behaviors, regimen self-adjustment, understanding of insulin-dependent diabetes mellitus (IDDM) treatment, attitudes about SMBG, and perceived quality of patient-physician interaction. Twenty-nine adolescent subjects (experimental) with IDDM were randomly assigned the Glucometer M system for 4 mo. Twenty-eight control subjects used meters without memory. All subjects returned twice to the clinic at 2-mo intervals during the study. At clinic visits, both groups reviewed their SMBG data with their physician. Reviews on experimental subjects were conducted with computer-generated data formats. Control subject reviews used traditional logbooks. Both groups showed a significant drop in glycosylated hemoglobin during the study period (P less than .001); however, there were no between-group differences. There were also no differences in SMBG testing behavior or self-reported regimen self-adjustment between groups or within groups compared with baseline. Compared with control subjects, experimental subjects indicated a significant increase in self-reported understanding of IDDM treatment (P = .002), perceived importance of testing (P = .006), and the quality of interaction with their physician (P less than .001). These data suggest that use of computer-assisted SMBG systems in the outpatient setting does not improve metabolic control over 4 mo. It may, however, contribute to improving communication between the patient and health-care providers.

Hormonal aspects of normal and abnormal behavior in adolescents. Study group report.

As stated initially, a significant proportion of health problems of youths have genetic predispositions and potentially identifiable antecedents of disease during childhood and adolescence. Until there is advancement in delineating the multiple dimensions and relationships of a psychobiologic developmental framework, interventions may fall short of their potential to either prevent or ameliorate these problems. To date, research has been limited by narrow definitions, lack of uniformity among measures, small samples, and homogenous populations. As a forward step, longitudinal investigations of subpopulations of youths may provide an opportunity for definitive study of the basic processes of puberty and be fruitful in evaluating the deleterious effects that stresses of contemporary life place on children and adolescents. In addition, efforts to communicate existing knowledge across disciplines and to approach psychobiologic research from an interdisciplinary perspective will enhance an understanding of the interplay of social, biologic, and environmental factors that are essential in the maturational process. This multidimensional approach with newer, broader perspectives is critical to advancing the development of a psychobiologic framework that will shed further light on the mechanisms of maturation and the interferences of this pubertal process that is the hallmark of adolescence.

Surreptitious insulin administration in adolescents with insulin-dependent diabetes mellitus.

Six adolescents, 12 to 15 years old, with insulin-dependent diabetes mellitus were discovered to be secretively taking extra insulin, not with the intent of improving metabolic control. Large discrepancies between reported and observed insulin requirements were noted. Psychosocial problems antedated the discovery of surreptitious insulin administration in all. Psychological testing and psychiatric evaluation revealed a variety of psychiatric conditions; depression was common. In two patients surreptitious insulin administration was believed to represent suicidal behavior. In others, it appeared to represent symptom substitution when use of other health-threatening behaviors such as recurrent ketoacidosis was made increasingly difficult through appropriate intervention. Surreptitious insulin administration may be one symptom of serious underlying psychiatric dysfunction in adolescents with insulin-dependent diabetes.

Normal sellar variations in frontal tomograms.

Frontal tomograms of 100 normal sellae were examined. The sellar floor was usually flat or had a smooth central depression of less than 2 mm. Six per cent had a marked central depression. In such cases, the lateral angles of the sellar floor, usually rounded, may be sharp, so that the diagnosis of intrasellar lesions cannot be based on such alterations. Where one or more septa divided the sphenoid sinus asymmetrically, sellar floor configuration was modified in 21% of cases. The normal sellar floor may have a slope of up to 8 degrees, making analysis of subtle contour variations difficult.

Computed tomographic positive contrast peritoneography.

Despite the use of intravenous and oral contrast material and antiperistaltic pharmaceuticals, abdominal computed tomography has limitations in the morphological study of the gastrointestinal tract, retroperitoneum, and pelvis. To better define these regions, positive contrast material was infused into the peritoneal space prior to abdominal CT. Results included: improved visualization of the peritoneal cavity and its contents; evident demarcation between the retroperitoneal space and intraperitoneal structures; sharp delineation of serosal surfaces of the bowel and solid viscera; and an obvious distinction between impinging bowel loops and pelvic organs.

Limitations of emergency room evaluations of sexually abused children.

A retrospective review was performed on charts of all children who were treated in 1975 in the Strong Memorial Hospital (Rochester, NY) emergency room for alleged sexual abuse, suspicious conditions, or complaints related to the genitourinary system, and on a randomly selected comparison sample of children treated for acute otitis media during the same period. In 44 cases of otitis media, pediatric house officers' charting uniformly evidenced adequate care. However, in ten cases of alleged sexual abuse and 29 cases considered suspicious, the evaluations and care were significantly (.01 greater than P less than .001) less adequate. The young pediatric house officer deals with these problems, which are complicated by emotional overtones and psychosocial implications, less effectively than those with more clear-cut, routine diagnoses.
