RESUMEN

BACKGROUND: Reasons for the strikingly increased rates of HIV and other sexually transmitted infections (STIs) among African Americans in the rural Southeastern United States remain unclear. Investigators have devoted little attention to the potential influence of the social and economic context on sexual behaviors. GOAL: To examine the potential influence of these contextual factors on behaviors that promote the transmission of STIs. STUDY DESIGN: Focus group interviews in which African Americans from rural North Carolina discussed life in their communities and contextual factors affecting sexual behavior. RESULTS: Respondents reported pervasive economic and racial oppression, lack of community recreation, boredom, and resultant substance abuse. Many perceived a shortage of black men because of their higher mortality and incarceration rates compared with whites, and believed this male shortage to be partly responsible for the concurrent sexual partnerships that they perceived as widespread among unmarried persons. CONCLUSION: Contextual features including racism, discrimination, limited employment opportunity, and resultant economic and social inequity may promote sexual patterns that transmit STIs.

RESUMEN

OBJECTIVES: Optimistic predictions for the Healthy People 2010 goals of eliminating racial/ethnic disparities in health have been made based on absolute improvements in life expectancy and mortality. This study sought to determine whether there is evidence of relative improvement (a more valid measure of inequality) in life expectancy and mortality, and whether such improvement, if demonstrated, predicts future success in eliminating disparities. METHODS: Historical data from the National Center for Health Statistics and the Census Bureau were used to predict future trends in relative mortality and life expectancy, employing an Autoregressive Integrated Moving Average (ARIMA) model. Excess mortality and time lags in mortality and life expectancy for blacks relative to whites were also estimated. RESULTS: Based on data for 1945 to 1999, forecasts for relative black:white age-adjusted, all-cause mortality and white:black life expectancy at birth showed trends toward increasing disparities. From 1979, when the Healthy People initiative began, to 1998, the black:white ratio of age-adjusted, gender-specific mortality increased for all but one of nine causes of death that accounted for 83.4% of all US mortality in 1998. From 1980 to 1998, average numbers of excess deaths per day among American blacks relative to whites increased by 20%. American blacks experienced 4.3 to 4.5 million premature deaths relative to whites in 1940-1999. CONCLUSIONS: The rationale that underlies the optimistic Healthy People 2010 forecasts, that future success can be built on a foundation of past success, is not supported when relative measures of inequality are used. There has been no sustained decrease in black-white inequalities in age-adjusted mortality or life expectancy at birth at the national level since 1945. Without fundamental changes, most probably related to the ways medical and public health practitioners are trained, evaluated, and compensated for prevention-related activities, as well as further research on translating the findings of prevention studies into clinical practice, it is likely that simply reducing disparities in access to care and/or medical treatment will be insufficient. Millions of premature deaths will continue to occur among African Americans.

RESUMEN

OBJECTIVES: To describe a case study of a community-based intervention located in the Harlem community of New York City, one of the oldest African-American communities in the United States. Although not specifically designed to prevent HIV infection, the program, 'Family to Family', exemplifies a 'structural intervention' that was created to strengthen family functioning and to strengthen the bonds that connect families to each other. By fostering strong relationships within and between families in a community with high rates of violence, drug abuse, and HIV infection, the program seeks to improve the quality of neighborhood life and influence the social determinants of individual risk behavior. SOCIAL CAPITAL: Family to Family was created specifically to develop the 'social capital' that is available to children and families in the Harlem community. Social capital refers to resources that result from social relationships, and that enhance an individual's or a group's ability to function and achieve a given set of goals and objectives. In addition to fostering closer relationships between children and their parents, this program also works to help participating families develop closer relationships with other participating families and with Columbia University student and faculty volunteers. Finally, Family to Family is sustained through the efforts of volunteers; it receives no grant support and is entirely self-supporting. CONCLUSIONS: Family to Family has the potential to change the social dynamics that promote HIV risk behavior in communities such as Harlem. Should it prove successful in improving the relationships between families and children, and in increasing the social capital available to all of its participants, it may become an important asset to public health prevention specialists concerned about preventing the spread of HIV.

RESUMEN

OBJECTIVES: One factor contributing to the decay of inner-city areas, and to consequent excess mortality, is the massive loss of housing. This report studied the effects of a redevelopment project on social functioning in an inner-city community. METHODS: This ethnographic study included the following elements: a longitudinal study of 10 families living in renovated housing, repeated observations and photographing of the street scene, focus groups, and informal interviews with area residents. The project was located in the Bradhurst section of Harlem in New York City and was focused on a redevelopment effort sponsored by local congregations. RESULTS: Those who were able to move into newly renovated housing found that their living conditions were greatly improved. Neighborhood revitalization lagged behind the rehabilitation of individual apartment houses. This uneven redevelopment was a visual and sensory reminder of "what had been." Residents missed the warmth and social support that existed in Harlem before its decline. CONCLUSIONS: Rebuilding damaged housing contributes greatly to the well-being of inner-city residents. The current pace and scope of rebuilding are insufficient to restore lost vitality.

RESUMEN

INTRODUCTION: In 1980, age-adjusted mortality rates in Central Harlem were the highest among New York City's 30 health districts. This population-based study was designed to describe the self-reported frequency of selected health conditions, behavioral risk factors, preventive health practices, and drug use in the Harlem community. METHODS: From 1992 to 1994, in-person interviews were conducted among 695 adults aged 18 to 65 years who were randomly selected from dwelling-unit enumeration lists for the Central Harlem health district. Descriptive statistics were computed for men and women separately, and compared to other population-based surveys. RESULTS: Self-reported medical insurance coverage in Harlem was unexpectedly high (74% of men, 86% of women) as was lifetime use of preventive health practices, e.g., blood cholesterol screening (58% of men, 70% of women). However, lifetime rates of substance use, e.g. crack cocaine (14%) and self-reported history of traumatic events, e.g., witnessing someone seriously injured or violently killed (49% of men, 21% of women) were also high in Harlem, especially in comparison to other populations. CONCLUSIONS: This study has identified important patterns of similarities and differences in risk behaviors between Harlem and other populations. Potential solutions to the health problems of Harlem may lie in the creation of strategies that operate at the community, municipal, and regional level, as well as at the level of individual behavior and risk-taking.

RESUMEN

Substance abuse has had a devastating impact on the lives of millions. As substance use and abuse continues to ravage communities, researchers remain in the dark about what works to ensure successful recovery from addiction. In searching for the answers, researchers have often overlooked the role of religious and spiritual practices and beliefs in preventing use and relapse. The study reported here describes the process of spiritual awakenings experienced by some persons in recovery during their quest for sobriety. The data suggests that persons in recovery often undergo life altering transformations as a result of embracing a power higher than one's self, that is, a Higher Power. The result is often an intense spiritual journey that leads to sustained abstinence. Given how widespread substance abuse is, research on the nature, implications, and limitations of a spiritual approach to addiction might offer new options for treatment.

RESUMEN

OBJECTIVES: Widespread violence affects individuals but also alters group life. This study was designed to examine the effects of violence on an inner-city community. METHODS: A qualitative study was undertaken that included field observations and semistructured interviews. The study took place in Washington Heights, a New York City neighborhood with a high rate of violence, largely secondary to the drug trade. RESULTS: The 100 people interviewed differed widely in their definitions of violence and in their likelihood of having experienced violent acts in the course of daily life. High, medium, and low violence microenvironments were identified; risk of exposure to violence, but not individual definitions of violence, differed by location. Violence in all parts of the neighborhood inhibited social interactions, but the intensity of this effect differed by microenvironment. CONCLUSIONS: In Washington Heights, violence has injured individuals and fractured social relationships, leading to the state of social disarray referred to as "anomie." The public health response to the violence epidemic should address anomie through community organizing efforts.

RESUMEN

Self-organized criticality offers more than a descriptive model or a doomsday forecast. We have tried to suggest that it is a paradigm for understanding the interconnections between apparently complex processes. At best, it suggests a method for finding the pressure points that can be used to bring unstable systems of public health services into greater levels of stability. The model enjoins us to understand that our goal is not to achieve equilibrium--that perfect match between the demand for health services and its delivery--but rather stability (or, more precisely, metastability). As is true of the sandpile, our systems of public health are constantly evolving. If we are correct, then the mechanism driving this ostensibly complex pattern of change and growth reflects the existence of simpler and, hopefully, more manageable processes. By monitoring these processes, it may be increasingly possible to adapt to change and even manage it effectively.

RESUMEN

BACKGROUND: To guide the development of an AIDS prevention program for urban minority high school students, the authors investigated the prevalence of AIDS-risk behaviors, and the relative explanatory power of demographic, contextual, and cognitive correlates of these behaviors, among black and Hispanic students in three New York City public high schools. METHODS: A survey was administered to a randomly selected sample of classrooms in the 9th through 12th grades of three public academic high schools in a New York City borough. Survey participants (n = 926) were 59% black and 34% Hispanic; the mean age was 16.4 (sd 1.4) years. RESULTS: Two-thirds of students reported having had sexual intercourse. Of the more than one-half of students who reported past-year intercourse, three-quarters had never or had inconsistently used condoms, one-third had multiple intercourse partners, one-tenth had a sexually transmitted disease, and one-twentieth had intercourse with a high-risk partner. Demographic (i.e., age, race/ethnicity) and contextual (i.e., academic failure, substance use, adverse life circumstances, cues to prevention) factors were most strongly associated with involvement in AIDS-risk behaviors; in contrast, cognitive factors (i.e., knowledge and beliefs about AIDS and AIDS-preventive actions) had little explanatory power. CONCLUSIONS: Addressing demographic and contextual risk factors for involvement in AIDS-related behaviors may prove to be a more powerful AIDS-prevention strategy among adolescents than simply teaching facts about AIDS and fostering prevention-related beliefs.

RESUMEN

The increasing prevalence of HIV infection among injection drug users mandates the development of innovative treatments. While extensive clinical experience suggests that acupuncture detoxification is both safe and acceptable to those in withdrawal, little research has been conducted to assess its efficacy as a treatment modality. In this first controlled study of acupuncture heroin detoxification, 100 addicted persons were randomly assigned, in a single-blind design, to the standard auricular acupuncture treatment used for addiction or to a "sham" treatment that used points that were geographically close to the standard points. Attrition was high for both groups, but subjects assigned to the standard treatment attended the acupuncture clinic more days and stayed in treatment longer than those assigned to the sham condition. Additionally, attendance varied inversely with self-reports of frequency of drug use, suggesting that those with lighter habits found the treatment modality more helpful. Limitations of the study are discussed.

RESUMEN

The recent spread of crack cocaine use among inner-city teenagers has been accompanied by dramatic increases in juvenile delinquency and sexually transmitted diseases (STDs) among teenagers. This study examined the prevalence of five factors which promote STDs, including human immunodeficiency virus (HIV), among a sample of sexually active black adolescent crack users and non-users from the San Francisco Bay Area. Significant differences were observed between these groups with respect to history of engaging in sexual intercourse under the influence of drugs or alcohol, exchanging sexual favors for drugs or money, condom use in the most recent sexual encounter, and having five or more sexual partners in the last year. Approximately 63% of all respondents reported engaging in at least one of these risk behaviors. In multiple logistic regression analysis, reporting one or more of these STD/HIV risk behaviors was significantly associated with crack use and having one or more relatives who used drugs. Intervention efforts need to address both individual and environmental risk factors in order to reduce teens' risk for STDs, including HIV.

PIP: Researchers combined data from two surveys conducted in the summer of 1988 to examine the association between sexually transmitted diseases (STD) risk behaviors and crack cocaine use among sexually active, black teenagers. All of the subjects lived in an inner city neighborhood in the San Francisco Bay Area in California. The Centers for Disease Control had earlier found a large increase in gonorrhea among black teenagers in San Francisco. Crack users were more likely the nonusers to have sexual intercourse under the influence of drugs or alcohol (43% vs. 11% for boys and 46% vs. 14% for girls; p .001), to take part in sexual acts placing them at risk for STD in exchange for money or drugs (29% vs. 4% for boys and 25% vs. 0 for girls; p .001), and to have more sexual partners in the last year (11.1 vs. 5.3 partners for boys; p .01 and 4.5 vs. 2.5 partners for girls; insignificant). Female nonusers were more likely to have used a condom during last sexual intercourse than were female crack users (39% vs. 18%; p .01). For both groups of boys, condom use during the last sexual act was at the same low rate (about 25%). Approximately 63% of all adolescents admitted to having at least one sexual risk behavior. Crack cocaine use and having at least one relative who used drugs were the greatest predictors of STD risk behavior (odds ratios, 2.2 and 1.97; p .001 and .01, respectively). An urban anthropology study in the same neighborhoods showed that the teenagers lived in an area conducive to high-risk behaviors including drug use common among friends and relatives, more than one sexual partner/year, high prevalence of STDs, and low condom use. The findings from these studies indicated that public health workers planning to implement interventions to prevent or reduce the risk of teenage drug use and/or HIV infection must consider both individual and environmental influences.

RESUMEN

To examine the actual and potential spread of human immunodeficiency virus (HIV) from an acquired immunodeficiency syndrome (AIDS) epicenter to surrounding neighborhoods, we studied the prevalence of the viral infection and AIDS risk behaviors from 1988 to 1989 in a representative sample of unmarried whites, African Americans, and Hispanics living in San Francisco. We surveyed 1,770 single men and women aged 20 to 44 years (a 64% response rate) in a random household sample drawn from 3 neighborhoods of varying geographic and cultural proximity to the Castro District where the San Francisco epidemic began. Of 1,369 with blood tests, 69 (5%) had HIV antibodies; all but 5 of these reported either homosexual activity (32% HIV-positive; 95% confidence interval [CI] = 23%, 41%), injection drug use (5% HIV-positive; CI = 1%, 14%), or both (59% HIV-positive; CI 42%, 74%). Homosexual activity was more common among white men than among African-American or Hispanic men, but the proportion of those infected was similar in the 3 races. Both the prevalence of homosexually active men and the proportion infected were much lower in the 2 more outlying neighborhoods. Risk behaviors in the past year for acquiring HIV heterosexually--sex with an HIV-infected person or homosexually active man or injection drug user, unprotected sexual intercourse with more than 4 partners, and (as a proxy) having a sexually transmitted disease--were assessed in 1,573 neighborhood residents who were themselves neither homosexually active men nor injection drug users. The prevalence of reporting at least 1 of these risk behaviors was 12% overall, and race-gender estimates ranged from 5% among Hispanic women to 21% among white women. We conclude that in San Francisco, infection with HIV is rare among people who are neither homosexually active nor injection drug users, but the potential for the use spread of infection is substantial, as 12% of this group reported important risk behaviors for acquiring the virus heterosexually.

RESUMEN

This study examines the impact of race and psychiatric symptomatology on the treatment of black patients with acquired immunodeficiency syndrome (AIDS). The study consisted of two parts: 1) focused group discussions with AIDS health professionals, and 2) a retrospective chart review of 44 hospitalized AIDS patients. The group discussions revealed that there are specific gaps in mental health services for all AIDS patients and that psychiatric and medical services must be delivered in an ethnically sensitive manner to be effective with black patients. The chart review revealed no statistically significant difference between black and white patients in terms of prevalence of psychiatric symptoms. The results of this study suggest that ethnically sensitive psychiatric diagnosis and treatment may have important clinical implications in the long-term management of black patients with AIDS.

RESUMEN

Crack cocaine is a smokable form of cocaine hydrochloride that has been associated with increases in admissions to drug treatment programs, and, recently, increases in the incidence of sexually transmitted diseases (STDs) among black teenagers. In an exploratory, cross-sectional study of the prevalence of risk behaviors that would promote the dissemination of STDs (including human immunodeficiency virus) among 222 black teenaged crack users, 41% of those interviewed reported a history of an STD. A history of an STD was more likely to be reported by girls (55%) than by boys (34%) and by those who combined crack use with sexual relations (51%) than those who did not (32%). The number of risk behaviors for STDs or human immunodeficiency virus reported by respondents (including failure to use a condom in one's most recent sexual encounter, having had a history of an STD, engaging in exchanges of sex for drugs or money, combining sexual activity with drug use, and reporting five or more sexual partners per year) was evaluated using multiple regression analysis stratified by gender. For girls, a history of selling crack and the number of reported risk behaviors (R = .46); for boys who chose the description "I don't know ahead of time if I'm going to have sex--it just happens" and the number of drugs used on a daily basis were associated with the number of reported risk behaviors (R = .31). Because of the impetuous nature of some crack-related sexual activity and because 76% of respondents acknowledged that they were either "very worried" or "somewhat worried" that they might get acquired immunodeficiency syndrome, it is possible that a program of widespread distribution of condoms in neighborhoods where crack use is prevalent might make it possible for the worried, impulsive crack user to practice "safer sex."
