Predicting substance abuse among youth with, or at high risk for, HIV.

This article describes data from 4,111 males and 4,085 females participating in 10 HIV/AIDS service demonstration projects. The sample was diverse in age, gender, ethnicity, HIV status, and risk for HIV transmission. Logistic regression was used to determine the attributes that best predict substance abuse. Males who were younger; HIV positive; homeless; involved in the criminal justice system; had a sexually transmitted disease (STD); engaged in survival sex; and participated in risky sex with men, women, and drug injectors were most likely to have a substance abuse history. For females, the same predictors were significant, with the exception of having an STD. Odds ratios as high as 6 to 1 were associated with the predictors. Information about sexual and other risk factors also was highly predictive of substance abuse issues among youth.

Service use patterns of youth with, and at high risk for, HIV: a care typology.

This paper uses confirmatory structural equation models to develop and test a theoretical model for understanding the service utilization history of 4679 youth who received services from 10 national HIV/AIDS demonstration models of youth-appropriate and youth-attractive services funded by the Special Projects of National Significance (SPNS) Program, HIV/AIDS Bureau, Health Resources and Services Administration. Although the projects differ from one another in the areas of emphasis in their service models, each is targeted to youth at high risk for HIV, or those youth who have already contracted HIV. Collectively, the projects represent a comprehensive adolescent HIV service model. This paper examines the characteristics of the services provided to young people ranging from outreach to intensive participation in medical treatment. Major typologies of service utilization are derived empirically through exploratory factor and cluster analysis methods. Confirmatory structural equation modeling methods are used to refine the exploratory results using a derivation and replication strategy and methods of statistical estimation appropriate for non-normally distributed service utilization indicators. The model hypothesizes that youth enter the service system through a general construct of connectedness to a comprehensive service model and through service-specific methods, primarily of outreach or emergency services. Estimates are made of the degree to which a comprehensive service model drives the services as opposed to specific service entry points.

Drug-involved women as potential users of vaginal microbicides for HIV and STD prevention: a three-city survey.

We wished to obtain potential users' perspectives on vaginal microbicides from a population of women at high risk for HIV. We conducted a face-to-face survey of convenience samples (total n = 743) of drug-using women and female sexual partners of male injection drug users in Bridgeport, Connecticut, Providence, Rhode Island, and San Juan, Puerto Rico. Ninety percent of respondents said that they would be very likely to use microbicides with paying partners and 78% with primary partners (p = 0.001). High hypothetical likelihood of use was expressed even after several potential product characteristics (e.g., causes minor vaginal irritation or burning) were rated as unacceptable. Latinas had significantly higher predicted likelihood of use with primary (p = 0. 001) and paying partners (p = 0.018) than blacks and whites. Eighty percent of respondents preferred products that enhance sexual pleasure by providing additional lubrication or "wetness." More than 80% of respondents said that they would want their primary partners to know of their microbicide use, and 42% (p = 0.001) said that they would want their paying partners to know. Women's concern about a paying partner's violent response to suggested use of risk reduction measures was inversely related to predicted likelihood of microbicide use (p = 0.045). Microbicides should be assessed in the context of the potential users' actual relationships and cultures. Achieving broad acceptability among drug-involved women will require a range of products.

Acceptability of formulations and application methods for vaginal microbicides among drug-involved women: results of product trials in three cities.

BACKGROUND AND OBJECTIVES: Female-controlled methods of HIV prevention, such as vaginal microbicides, are urgently needed, particularly among drug-involved women. Acceptability research is critical to product development. GOAL: To assess the acceptability of forms and application methods for future microbicides. DESIGN: Eighty-four drug-involved women were introduced in groups to three lubricant products, asked to try each for 3 weeks, and scheduled for individual follow-up interviews. RESULTS: Participants and their partners felt positive about the products, and expressed willingness to use microbicides if they were shown to be effective against HIV. Women agreed on product characteristics that influenced their reactions (e.g. ease of insertion, degree of "messiness"), but often disagreed on whether their reactions to these characteristics were positive or negative. CONCLUSION: Development of acceptable and effective HIV-prevention products depends on understanding the interaction between characteristics of the products and the characteristics and perceptions of women. Levels of sexual risk and acceptability factors based on drug-use patterns, race and ethnicity, culture, age, and types and attitudes of male partners suggest that a "one size fits all" approach will not win broad acceptance among drug-involved women.

Risk factors and characteristics of youth living with, or at high risk for, HIV.

Over 8,000 adolescents and young adults (4,111 males; 4,085 females) reported on several HIV-related risk behaviors during enrollment into 10 service demonstration projects targeted to youth living with, or at risk for, HIV. Distinct risk patterns emerged by gender when predicting HIV serostatus (versus unknown serostatus/negative serostatus). Males who had injection drug risk histories, had sex with an HIV positive partner, had sexually transmitted diseases, had sex with males, and/or were homeless had an inflated risk of being HIV positive. Females who engaged in sex with an HIV partner, had sex with an injection drug user, and/or had sexually transmitted diseases, were at the highest HIV risk. For both samples, engaging in sex with women reduced the likelihood of HIV positive status. Very basic information about risk factors obtained at service intake offers important information about HIV status of "high risk" youth presenting for care in community programs, as well as suggests clear risk factors for targeted preventive efforts.

Bridgeport's Teen Outreach and Primary Services (TOPS) project: a model for raising community awareness about adolescent HIV risk.

The Greater Bridgeport Adolescent Pregnancy Program (GBAPP), based on its skills in sex education, pregnancy, and sexually transmitted disease prevention, developed the Teen Outreach and Primary Services (TOPS) project, an innovative teen-focused community outreach model to expand and ensure access to health and support services for primarily underserved minority adolescents and young adults at risk for or living with the human immunodeficiency virus (HIV). TOPS is supported by the Special Projects of National Significance Program, HIV/Acquired Immunodeficiency Syndrome (AIDS) Bureau, Health Resources and Services Administration. The target population for TOPS is inner-city minority youth (ages 15-24 years) at high risk for HIV or HIV positive. Services ranging from outreach to intensive case management were provided to 2173 youth in the project. The number of HIV-positive youth has increased from three in the first year of the project to 17 in 1997. TOPS provides outreach, case management, HIV counseling and testing, risk-reduction activities, and referrals for housing, entitlements, specialty HIV clinics, and substance abuse counseling and treatment. A group of peer educators has been recruited from among the target population and is trained and paired with the staff to provide outreach services, peer counseling, and education, and to assist with recreational opportunities.

An evaluation of the Vita-Stat automatic blood pressure measuring device.

Four Vita-Stat (VS) automatic, coin-operated, blood pressure measuring devices were evaluated for accuracy and precision. Under field conditions, 342 adults had two blood pressure measurements with both the VS device and with the Random-Zero (RZ) device. Two of the VS machines gave significantly higher systolic (SBP) and diastolic blood pressure (DBP) values, compared to the RZ values. The mean difference between these two units and the RZ device were clinically important (14.0 and 6.9 mm Hg SBP; 7.5 and 6.8 mm Hg DBP), and resulted in the misclassification of 23% of normotensives as hypertensives. We observed a significant order effect on SBP with the VS device, with a mean decrement of 4.9 mm Hg between the first and second SBP values, compared to 0.6 mm Hg with the RZ device. Even after adjusting for this bias, all four VS devices gave significantly more variable SBP readings than the RZ unit; two of the four also gave more variable DBP values. These data suggest that the VS device is neither accurate nor precise enough at the present time to be recommended for widespread use. These findings also raise questions concerning the monitoring of performance of this and similar devices in the field.

Shared experiences: three programs serving HIV-positive youths.

This article presents the major components of three models of linked psychosocial care for HIV-positive youths and youths at high risk for HIV infection: YouthCare (Seattle, Washington), TOPS Program (Bridgeport, Connecticut), and Boston HAPPENS (Boston, Massachusetts). These models were developed to connect hard-to-reach and otherwise marginalized youths to needed services. All sites have successful programs that are well integrated with their communities' systems of care for HIV-positive adolescents. The projects share their program elements, successes, and challenges. Practical suggestions are offered to those interested in providing and evaluating youth-oriented HIV care programs.
