BACKGROUND Although the rate of death from injuries due to violent acts is much higher among black women than among white women in the United States, little is known about the nature and correlates of violent injuries among black women living in urban areas. METHODS In this case-control study conducted at three emergency departments in one inner-city community (in west Philadelphia), we studied 405 adolescent girls and women who had been intentionally injured and 520 adolescent girls and women (control subjects) who had health problems not related to violent injury. Data were collected by conducting standardized interviews with use of questionnaires and by screening urine for illicit drugs. Individual logistic-regression models were constructed to identify factors associated with violent injuries inflicted by partners and those inflicted by persons other than the partners of the victims. RESULTS The male partners of the injured women were much more likely than the male partners of control subjects to use cocaine (odds ratio, 4.4; 95 percent confidence interval, 2.3 to 8.4) and to have been arrested in the past (odds ratio, 3.1; 95 percent confidence interval, 1.8 to 5.2). Fifty-three percent of violent injuries to the women had been perpetrated by persons other than their partners. Womens use of illicit drugs and alcohol abuse were factors associated with both violence on the part of partners and violence on the part of other persons. Neighborhood characteristics, including low median income, a high rate of change of residence, and poor education, were independently associated with the risk of violent injuries among women. CONCLUSIONS Women in this urban, low-income community face violence from both partners and other persons. Substance abuse, particularly cocaine use, is a significant correlate of violent injuries. Standard Census data may help identify neighborhoods where women are at high risk for such violence and that would benefit from community-level interventions.

PURPOSE To investigate the association of psychological distress and health risk behaviors among HIV infected adolescents. It was hypothesized that higher levels of distress would be associated with increased sexual risk behaviors, and increased use of alcohol and drugs. METHODS HIV infected adolescents (N = 323) were recruited into an observational study in 15 clinical sites; for the 323 subjects, a total of 1212 visits were used in a repeated measures analysis. Data on depression (using the CES-D), anxiety (manifest anxiety scale), sexual behaviors and alcohol and marijuana use were obtained through computer-assisted self-administered interview. RESULTS Approximately 65% of the sample was sexually active across all six study visits, with approximately 43% consistently reporting having unprotected sex at last intercourse. Higher levels of depression were associated with frequent alcohol use and with unprotected sex at last intercourse, with depressed adolescents significantly more likely to have had unprotected sex than those who were not depressed. Health anxiety was associated with frequent marijuana use and with recent sexual activity, and physiological anxiety was also associated with recent sexual activity. CONCLUSIONS Despite the fact that these HIV infected adolescents are all engaged in primary care, overall the sample is maintaining its high-risk sexual behavior. In addition, these adolescents may be self-medicating to deal with health-related anxiety. Health interventions for HIV infected adolescents should examine whether psychological distress is contributing to maintenance health risk behaviors.

Background:Many patients use emergency departments (EDs) for primary care. Previous studies have found that patient characteristics affect ED utilization. However, such studies have led to few policy changes. Objectives:We sought to determine whether Medicaid patients’ ED use is associated with characteristics of their primary care practices. Research Design:This was a cohort study. Subjects:A total of 57,850 patients, assigned to 353 primary care practices affiliated with a Medicaid HMO, were included. Measures:Predictor variables were characteristics of primary care practices, which were measured by visiting each practice. The outcome variable was ED use adjusted for patient characteristics. Results:On average, patients made 0.80 ED visits/person/yr. Patients from practices with more than 12 evening hours/wk used the ED 20% less than patients from practices without evening hours. A higher ratio of the number of active patients per clinician-hour of practice time was associated with more ED use. When more Medicaid patients were in a practice, these patients used the ED more frequently. Other factors associated with ED use included equipment for the care of asthma and presence of nurse practitioners and physician assistants. Discussion:Modifiable characteristics of primary care practices were associated with ED use. Because the observational design of this study does not allow definitive conclusions about causality, future studies should include intervention trials to determine whether changing practice characteristics can reduce ED use. Conclusions:Improving primary care access and scope of services may reduce ED use. Focusing on systems issues rather than patient characteristics may be a more productive strategy to improve appropriate use of emergency medical care.

OBJECTIVES Injury is a major US public health problem, particularly in urban minority communities. This paper evaluates the impact of the Safe Block Project, a comprehensive injury prevention trial, on home hazards and injury prevention knowledge in a poor urban African-American community. METHODS Nine census tracts in the community were allocated to either the intervention area or the control area. The intervention, carried out by trained community outreach workers, consisted of (1) home modification for simple prevention measures, (2) home inspection accompanied by information about home hazards, and (3) education about selected injury prevention practices. Approximately 12 months after the intervention, random samples of control and intervention homes were assessed for home hazards and injury prevention knowledge. RESULTS A significantly larger proportion of intervention homes than control homes had functioning smoke detectors, syrup of ipecac, safely stored medications, and reduced electrical and tripping hazards. No consistent differences were observed between control and intervention homes on home hazards requiring major effort to correct. CONCLUSIONS There was a distinct difference between control and intervention homes with respect to safety knowledge and home hazards requiring minimal to moderate effort to correct. The Safe Block Project could serve as a model for future urban injury prevention efforts.

OBJECTIVES To assess prevalence of victimization and perpetration of relationship violence before and during college, to explore variations by gender, and to examine differences by relationship type. DESIGN Anonymously surveyed students in 67 randomly chosen classes. SETTING Three urban college campuses. PARTICIPANTS Nine hundred ten undergraduate college students aged 17 to 22 years. MAIN OUTCOME MEASURES Self-reported victimization and perpetration of physical, emotional, and sexual violence; relationship to the victim or perpetrator. RESULTS Most (57.1%) students were female, and 58.7% were white, 16.4% black, and 15.1% Asian. Of 910 participants, 407 (44.7%) experienced partner or nonpartner violence: 383 (42.1%) reported victimization and 156 (17.1%) reported perpetration. All victimization and perpetration rates were highest before college. Emotional violence was most common before college (21.1%); during college, sexual and emotional violence were equally common (12.0% and 11.8%, respectively). Women reported more victimization than men, but male victimization was considerable (27.2%). More men perpetrated sexual violence; more women perpetrated physical violence. More than half (130 of 227) of the violence experienced during college was partner related. Students experiencing partner violence during college were more likely to experience physical and emotional violence and were less likely to experience sexual violence. CONCLUSIONS Relationship violence is prevalent among college students and frequently occurs before college. Emotional violence was most frequent before college; sexual and emotional violence were equally common during college. Women reported more victimization than men, but male victimization was common. Men perpetrated more sexual violence; women perpetrated more physical violence. Physical violence and emotional violence were most often committed by partners, while sexual violence was less likely to be partner related.

Introduction Epidemic increases in obesity negatively affect the health of US children, individually and at the population level. Although surveillance of childhood obesity at the local level is challenging, height and weight data routinely collected by school districts are valuable and often underused public health resources. Methods We analyzed data from the School District of Philadelphia for 4 school years (2006–2007 through 2009–2010) to assess the prevalence of and trends in obesity and severe obesity among public school children. Results The prevalence of obesity decreased from 21.5% in 2006–2007 to 20.5% in 2009–2010, and the prevalence of severe obesity decreased from 8.5% to 7.9%. Both obesity and severe obesity were more common among students in grades 6 through 8 than among children in lower grades or among high school students. Hispanic boys and African American girls had the highest prevalence of obesity and severe obesity; Asian girls had much lower rates of obesity and severe obesity than any other group. Although obesity and severe obesity declined during the 4-year period in almost all demographic groups, the decreases were generally smaller in the groups with the highest prevalence, including high school students, Hispanic males, and African American females. Conclusion Although these data suggest that the epidemic of childhood obesity may have begun to recede in Philadelphia, unacceptably high rates of obesity and severe obesity continue to threaten the health and futures of many school children.

Even though injuries are a leading cause of morbidity and mortality among the elderly in the United States, no comprehensive population‐based study of nonfatal and fatal injuries has been carried out in an elderly minority inner‐city population. To study injuries in this population, we developed an active surveillance system as part of a large injury prevention program in a poor urban black community. We report 577 cases of nonfatal and fatal injuries in a community of 12,139 persons 65 years of age and older that resulted in emergency room treatment or death between March 1, 1987, and February 29, 1988.

Objectives. To identify systematic problems in coordinating care for inner-city minority youths with attention-deficit/hyperactivity disorder. Methods. We recruited participants from inner-city minority communities in a single metropolitan area for a focus group study. We held separate meetings for pediatricians, mental health therapists, school staff, and parents (both black and Latino). We audiotaped and transcribed the meetings. We identified themes by consensus and used root cause analysis as a conceptual framework to guide our analysis. Results. We held 13 focus group meetings. Participants uniformly perceived insufficient communication and coordination of care. Five themes representing system and human factors that contributed to this fragmentation in care emerged: (1) a lack of consensus about who should oversee care; (2) changes in health care providers or teachers; (3) uncertainty in the diagnosis, insufficient training, and few resources; (4) distrust and blame that emerged when relationships among people who care for the child were absent or otherwise inadequate; and (5) lack of support from employers, friends, and family to engage in collaborative care. Conclusions. Using a root cause analysis framework, we identified system- and human-level factors that were perceived to impede communication and coordination of care for this population of children with attention-deficit/hyperactivity disorder. These results suggest that better organizational policies that define provider responsibilities and accountability, support the coordination of care, bridge relationships between agencies, and provide additional education and resources may improve collaboration. Additional study is needed to assess the generalizability of these finding to other settings.

OBJECTIVE. The purpose of this work was to explore the knowledge, attitudes, and beliefs of urban, minority adolescent girls about intention to use emergency contraception pills and to identify barriers to emergency contraception pill use. PATIENTS AND METHODS. We conducted an in-depth, semistructured interview study of healthy, urban-dwelling, English-speaking 15- to 19-year-old black adolescents seeking care in a childrens hospital emergency department. Purposive sampling was used to recruit sexually active and nonsexually active adolescents and those with and without a history of pregnancy. Enrollment continued until saturation of key themes was achieved. Participants returned after their emergency department visit for a 1-hour interview. The interview consisted of semistructured questions based on the theory of planned behavior constructs: attitudes (including knowledge), subjective norms, and perceived behavioral control, as well as demographic data collection. Interviews were recorded and transcribed. Transcripts were coded by 2 members of the study team by using a modified grounded-theory method. RESULTS. Thirty interviews were required for saturation. Mean participant age was 16.4 years; 53% reported being sexually active, and 17% reported a history of pregnancy. Specific knowledge gaps exist about emergency contraception pills, including misconceptions about the recommended time frame for taking the medication. Several major themes were noted for each of the constructs. Intention to use emergency contraception pills is affected by the conflicting attitudes that the emergency contraception pill works faster than birth control pills and that those who use emergency contraception pills are irresponsible; family and friends are important influences and have uninformed but generally supportive opinions; and adolescents have a perception of limited behavioral control because of their young age and concerns about confidentiality. CONCLUSIONS. Urban, minority adolescent girls have misconceptions about emergency contraception pills, are affected by the opinions of those close to them, and express concern about specific barriers. These findings can inform specific interventions aimed at addressing the barriers to emergency contraception pill use that are of most importance to this population of young women.
