HIV Testing Program Activities and Challenges in Four U.S. Urban Areas.

The national "Ending the HIV Epidemic: A Plan for America" supports expanded testing in jurisdictions and groups with disproportionate HIV burden. Public health planners benefit from learning HIV testing service (HTS) strengths, challenges, and innovations. We conducted semistructured interviews with 120 HTS staff from local health departments, community-based organizations, and community members in Houston, Texas; Miami, Florida; New Orleans, Louisiana; and Washington, DC. We coded interview transcripts using qualitative methods to identify themes. Program strengths include HIV testing integration with other client services; prioritized testing and tailored incentives; multiple advertising methods; and partnerships among HTS providers. Challenges include stigma, fear, and disparities; funding requirements that create competition between providers; and service accessibility, unnecessary repeat testing, and insufficient innovation. The four jurisdictions addressed some, but not all, of these challenges. Cross-jurisdictional collaboration, together with state and federal partners plus program data may help identify additional strategies for strengthening HTS.

Basic data on visits to family planning services sites: United States, 1980.

PIP: Cross tabulations of data from the National Reporting System for Family Planning Services are presented. Information was collected on the sociodemographic characteristics of patients as well as family planning service utilization. A sample of private facilities as well as those supported by Public Health Services family planning grants were selected to participate in the survey. The family planning visit is the basic sampling unit and the proportion of visits selected from each site varies with geographic location and annual visit volume. Only visits made by women were included. The Clinic Visit Record (i.e., the data collection form) contains 14 items: identifying information (2 items), date, sex, determination of hispanic origin, race, birthdate or age if unknown, prior utilization of family planning services, educational attainment, family income and family size, pregnancy history, contraceptive history, medical services received, and contraceptive method chosen at conclusion of visit. The results are presented in 12 tables. The data estimate 9,261,000 family planning visits were made in 1980, only 19% were 1st visits. 89% of the visits were made by women under the age of 30; teenagers comprise 1/3 of this group. Women of hispanic origin made 12.6% of the total visits. 80% of all visits were made by women with 12 years of education or less and 14% by women from families receiving public assistance. 54% of the women were nulliparous. In 89% of the visits, some method of contraception was adopted or continued (68% chose oral contraceptives, 7.2% IUDs and 6.5% diaphragms). Prior contraception use was reported by women comprising 82% of the visits. 40.3 million medical services, including blood pressure checks, pelvic examinations, breast examinations and Pap smears, were provided.^ieng

Collaborative AIDS prevention research in the developing world: the CAPS experience.

BACKGROUND: Prevention through behavior change is the only way to control the spread of HIV infection in the developing world. Success in prevention requires consistent and persistent intervention over time, a clear understanding of the realities of target populations and involvement of members of these populations in prevention efforts. Applied local research is urgently needed, especially in the developing world, to design interventions that meet these criteria and to test their effectiveness. CENTER FOR AIDS PREVENTION STUDIES (CAPS) MODEL OF INTERNATIONAL COLLABORATIVE RESEARCH: Each year, eight to 10 scientists from developing countries visit CAPS in San Francisco for 10 weeks of intensive learning and collaboration. The main emphasis is on designing a protocol for a research project related to AIDS prevention in the visiting scientist's home country. CAPS provides pilot study funding and technical assistance to implement the project. RESULTS: The quality of the resulting collaborative research is represented by the articles published in this volume and by the many alumni of the program who have undertaken additional research projects and/or assumed leadership positions in AIDS control efforts in their countries.

PIP: Prevention through behavior change is the only way to control the spread of HIV infection in the developing world. Success in prevention requires consistent and persistent intervention over time, a clear understanding of the realities of target populations, and involvement of members of these populations in prevention efforts. Applied local research is urgently needed, especially in the developing world, to design interventions that meet these criteria and to test their effectiveness. The Center for AIDS Prevention Studies (CAPS) model of international collaborative research has been used at the University of California, San Francisco, for the past eight years. The model involves an intensive period for protocol development and another one for data analysis. Each year, 8-10 scientists from developing countries visit CAPS in San Francisco for 10 weeks of intensive learning and collaboration. They are immersed in HIV epidemiology, research design, computer skills, data management, and psychosocial aspect of the AIDS epidemic. The main emphasis is on designing a protocol for a research project related to AIDS prevention in the visiting scientist's home country. The greatest impediment to intervention trials in developing countries is lack of funding. CAPS provides pilot study funding and technical assistance to implement the project in the home country. In the summer of 1995 eight alumni worked intensively with the CAPS faculty on data analysis and manuscript preparation. The quality of the resulting collaborative research is represented by the articles published and by the many alumni of the program who have undertaken additional research projects and/or assumed leadership positions in AIDS control efforts in their countries. These studies cover a wide range of risk groups, including sexually transmitted disease patients in Zambia; adolescents in the Philippines and Russia; wives of HIV-infected men in Uganda; female sex workers in Brazil, India, and Thailand; and HIV-infected women of childbearing age in Rwanda.

Integration of AIDS program activities into national health systems.

In this paper we have defined integration as being the health unit team acceptance of responsibility for all aspects of care at the health service/community interface level. The health unit functions within a system whose elements (hospitals, laboratory, pharmacy, etc.) function in complementarity with those of the FLHS. Vertical approaches are often adopted because of weaknesses in some elements of the NHS, thereby further undermining such an NHS. The development of innovative community-based approaches in some areas and countries has resulted from this type of situation. However, isolated from the NHS, such approaches cannot be expected to be sustainable or to have long-term impact. Integration is the best choice of approach; it offers a chance to influence the course of the AIDS epidemic and the response of health systems in each country. The basic structure of the NHS and the characteristics of a FLHS are analyzed. The challenge to AIDS programs is to define more exactly objectives and activities at the operational, interface levels. Based on this analysis, planning of operations should be delegated to the district. Weakness of some elements and aspects of the NHS which are relevant to AIDS control program implementation can be overcome, not by organizing the program vertically and independently from the NHS, but rather by sharing resources to strengthen the weak elements. Integration may be more difficult in the early stages of implementation, but in the long term it offers sustainable development of AIDS prevention and control activities.

PIP: This paper reviews the integration of AIDS program activities into national health systems as a possible way to make the activities more effective, efficient, and sustainable. For the purposes of this paper, integration is the health unit team acceptance of responsibility for all aspects of care at the health service/community interface level. Consideration is limited to the integration of AIDS control activities into national health systems, but the concept of integration is also applicable to other sectoral service systems such as education, religion, and rural development. The integration of activities will become a prerequisite for sustainability as the AIDS epidemic spreads. While such integration may be difficult in the early stages of implementation, it offers the sustainable development of AIDS prevention and control activities over the long term. Examples of the successful integration of AIDS activities into other health programs need to be studied in order to identify what is the most effective form of integration. The authors discuss integration and vertical approaches, and the structure of the national health service and characteristics of first-line health services.

HIV and intravenous drug use.

There is now evidence from a wide variety of geographic areas that many intravenous drug users will change their behavior in order to reduce their risk of developing AIDS. There is even evidence from some areas that the behavior change has led to relative stabilization of seroprevalence rates, although longer-term studies will be needed to establish this definitively. AIDS behavior change in the area of sexual risk reduction appears to be much more difficult than change of drug injection behavior. Conceptual models of AIDS-related behavior change are needed, particularly models that can incorporate the injection of different drugs and variation in social and psychological characteristics among drug injectors. There is increasing evidence for a wider spectrum of HIV-related morbidity and mortality among intravenous drug users than is captured by the current surveillance definition for AIDS, again emphasizing the need for effective prevention programs.

PIP: Topics concerning intravenous drug use and AIDS are reviewed. Topics include seroprevalence of HIV among users worldwide, evidence that iv drug users will alter behavior to avoid AIDS, results of safer injections programs, no evidence for reduction in high-risk behavior regarding sexual transmission of AIDS by users, diversity in HIV prevalence among users, and clinical aspects of their disease. Seroprevalence of HIV among drug users has remained at about 30% in the U.S. and parts of Europe, while lower in Asia and South America. There is now evidence from several places in Europe and the U.S. that many iv drug users will change drug injecting behavior to avoid AIDS. A conceptual model of new social norms needed to change behavior involves 3 stages: knowing the dangers of AIDS, having the means to change behavior (treatment or clean syringes), and a mechanism to reinforce the new behavior (perceived efficacy or social approval). There is no evidence that safer injection programs either keep users from going to treatment or increase numbers of users. In contrast, there is no evidence for improved sexual risk-taking behaviors among users, a fact which argues for stronger efforts to prevent already infected users from spreading HIV. The public, policy-markers, and researchers are unaware that seroprevalence of HIV varies with the type of drug injected (cocaine; heroin; amphetamine), and with socioeconomic status of the user (ethnic minority; majority). The clinical presentation, infection rate, persistence of infection, and mortality rate among iv drug users differs from that of the general AIDS population. Endocarditis, tuberculosis and bacterial pneumonias are 3 of the common findings in drug users. Even "non-AIDS" deaths apparently due to immunosuppression are reported in drug users. There may be undiscovered co-factors in HIV infection in this population.

Men with sexually transmitted diseases in Bangkok: where do they go for treatment and why?

OBJECTIVES: To describe and identify predictors of health-care seeking behavior among men with sexually transmitted diseases (STDs) in Bangkok, Thailand. DESIGN: Cross-sectional survey. METHODS: Men presenting with STDs were recruited from government clinics (n = 101), private clinics (n = 50) and pharmacies (n = 62). They completed interviewer-administered questionnaires on risk behavior, patterns of treatment-seeking for current and past STDs and attitudes toward health care. RESULTS: Two-thirds of all subjects had had a previous STD. Approximately one-half believed a partner other than a sex worker was the source of their current infection. Of the sample, 39% of men seen initially at drugstores, 29% at private clinics and 19% at government clinics sought subsequent treatment; failure to respond to therapy was the primary reason for seeking additional care. Men attending drugstores were likely to be younger, have less education and income, and to practice riskier sexual behavior. Patients at drugstores and general private clinics received the least amount of counseling or STD testing, while those attending specialized private STD clinics received the most comprehensive services. Attitudes towards government clinics were uniformly positive regardless of the site of enrollment; conversely, about 50% of clients at drugstores felt that the advice and treatment they received were inadequate. Convenience, affordability and lack of embarrassment were associated with choice of treatment site. CONCLUSIONS: STD/HIV control in Thailand must focus on improved treatment and counseling at the point of first encounter in the health-care system, particularly in the private sector. Men may be dissuaded from attending government clinics because of lack of convenience. Syndromic case management, incorporation of STD care at other public clinics and the recognition that more men practice unsafe sex with partners other than sex workers could improve STD control.

PIP: The determinants of treatment-seeking behaviors associated with sexually transmitted diseases (STDs) were investigated in a cross-sectional survey of 213 men recruited from government clinics (n = 101), private clinics (n = 50), and pharmacies (n = 62) in Bangkok, Thailand. 142 of these men had had a prior STD. 34% of men who initially attended pharmacies and 19% of those who first attended a government clinic sought multiple treatments for prior STDs because of an incomplete response to treatment. 50% of STD clients had visited a commercial sex worker in the 3 months preceding the current STD; half believed a casual or new sex partner was the source of infection. 12% of men had sex while they were symptomatic with the current STD. Advice on condom use was conveyed to 88% of government clinic patients, 94% of private clinic patients, and 52% of pharmacy customers; only 72%, 14%, and 22%, respectively, were urged to contact their sexual partner. Men with less education and symptoms of dysuria were more likely to seek care at drugstores. Also associated with seeking care at a pharmacy rather than a government site were waiting less than 7 days to seek treatment, having a travel time less than 20 minutes, and feeling able to pay for treatment. Those seeking care at pharmacies were also more likely to believe that they would recover at least as well as those treated at a government clinic and to believe they were at risk for human immunodeficiency virus infection. Possible strategies for improving STD treatment at the first point of contact within the health care system include promotion of syndromic STD management among pharmacists and general practitioners, integrated STD programs within health care services already providing care to adolescents and other high-risk groups, and strengthening the referral network to government clinics.

Evidence of marked sexual behavior change associated with low HIV-1 seroconversion in 149 married couples with discordant HIV-1 serostatus: experience at an HIV counselling center in Zaire.

To determine the effect of an HIV-1 counselling program on 149 married Zairian couples with discordant HIV-1 serology, the rates of HIV-1 seroconversion and reported condom utilization have been observed during 382.4 person-years of follow-up (minimum follow-up time per couple of 6 months). Before determination of HIV-1 serostatus and counselling, less than 5% of these couples had ever used a condom. One month after notification of HIV-1 serostatus and counselling, 70.7% of couples reported using condoms during all episodes of sexual intercourse. At 18 months follow-up, 77.4% of the 140 couples still being followed reported continued use of condoms during all episodes of sexual intercourse. At the time of notification of HIV-1 serostatus, 18 couples experienced acute psychological distress. Home-based counselling by trained nurses resolved these difficulties in all but three couples who subsequently divorced. Intensive counselling following notification of HIV-1 serostatus led to low rates of HIV-1 seroconversion (3.1% per 100 person-years of observation) in Zairian married couples with discordant HIV-1 serostatus who voluntarily attended an HIV counselling center.

Couple communication, sexual coercion and HIV risk reduction in Kigali, Rwanda.

OBJECTIVE: To describe sexual interaction and HIV-related communication in Rwandan couples and to examine their relationship to HIV testing and condom use. STUDY DESIGN: Cross-sectional survey of a longitudinal cohort. METHODS: In 1988, women recruited for an epidemiological study of HIV, and interested male partners, received confidential HIV testing and counseling. Two years after enrollment, 876 women reporting one steady partner in the past year completed a questionnaire addressing sexual and HIV-related communication, sexual motivation and violence in the partnership. RESULTS: Men control sexual decision making, and coercive sex and violence between partners is not uncommon. HIV-positive women were more likely to report coercive sex and less likely to have discussed their test results with their partner. Women with HIV-positive partners were more likely to report being physically abused. Condom use was more common if the man had been previously tested, and if women reported discussing or negotiating condom use. HIV-negative women with untested or seronegative partners were the least likely to use condoms or to discuss or attempt to negotiate condom use. CONCLUSIONS: Participation of the male partner is crucial for successful HIV risk reduction in couples. HIV testing and counseling of couples has beneficial long term effects on condom use and HIV-related communication. Couple communication is associated with condom use, but only when the discussion is specific (sexually transmitted disease risks and using condoms). Seronegative women with untested partners are at increased risk for HIV as they are the least likely to discuss or attempt to negotiate condom use.

PIP: The salience of couple communication to the prevention of human immunodeficiency virus (HIV) was demonstrated in a study of 876 Rwandan women with one steady sexual partner in the preceding year. These women were part of a longitudinal study of the natural history of HIV infection involving 1458 mothers recruited from prenatal and pediatric clinics at a Kigali Hospital in 1988. At study entry, 234 (27%) of the 876 monogamous women were HIV-positive; 45 additional women had seroconverted by the time of the two-year follow-up. Among the 855 sexually active subjects, only 196 (23%) were using condoms. Condom use was substantially higher among HIV-positive women (39%) than their HIV-negative counterparts (17%). In addition, condom use was significantly more likely if the woman had discussed condoms with her partner or if the male partner had agreed to an HIV test. Seronegative women with untested or HIV-negative partners were the least likely to discuss or use condoms. Notable was a pattern of male control of sexual decision making and female responsibility for condom provision, coercive sex, and domestic violence. 33% of women had been forced to have sex with their partner against their will and 21% had been beaten; these rates were even higher among HIV-positive women or HIV-negative women with infected partners. Given the disproportionate power of men in sexual relations in many African societies, efforts to strengthen women's condom negotiation skills may be counterproductive. Recommended, instead, are interventions that increase male involvement in HIV testing and counseling.

Declining risk for HIV among injecting drug users in Kathmandu, Nepal: the impact of a harm-reduction programme.

OBJECTIVE: To measure changes in self-reported risk behaviour for HIV infections and HIV seroprevalence among injecting drug user (IDU) clients of an outreach harm-reduction programme in Kathmandu, Nepal. METHODS: The Lifesaving and Lifegiving Society (LALS) of Kathmandu began providing sterile injecting equipment and education to Nepalese IDU in 1991. A sample of these IDU were interviewed and tested for HIV each year from 1991 through 1994. RESULTS: Indicators of unsafe injecting fell, as knowledge of HIV rose more in 1994 for those who had been in touch with LALS for longer. Indicators of unsafe sex did not change. HIV seroprevalence remained low, 1.6% in 1991 and 0% in 1994. CONCLUSION: We conclude that programmes for the prevention of HIV spread among IDU are possible and effective in Asia, and are urgently needed.

PIP: To reduce the high rate of human immunodeficiency virus (HIV) infection among intravenous drug users in Nepal, the Lifesaving and Lifegiving Society of Kathmandu has been distributing sterile injecting equipment in exchange for contaminated materials since 1991. In addition, community health outreach workers affiliated with the program provide condoms and bleach, HIV counseling and education, and primary health care to about 750 of the estimated 1500-2000 intravenous drug users in the Kathmandu valley. Of the 48,386 client contacts in 1991-94, over half involved syringe exchange. During this period, 586 randomly selected clients were selected for interviews and serologic testing. The number of times drug users shared equipment declined from 14 times per week in the 1991 subsample to once a day or less in the 1993 and 1994 subsamples. Knowledge of HIV infection rose from 58% in 1991 to almost 100% in 1994, while the proportion of drug users considering themselves at risk of HIV increased from 25% to 47%. There were no significant changes in HIV seropositivity (1.6% in 1991) during the study period, and no new cases were recorded in 1993 or 1994. This finding confirms the effectiveness of needle/syringe exchange programs in controlling the spread of HIV infection among intravenous drug users.

Impact of an intervention on HIV, sexually transmitted diseases, and condom use among sex workers in Bombay, India.

OBJECTIVE: To develop and test an HIV intervention targeting sex workers and madams in the brothels of Bombay. SUBJECTS AND METHODS: In a controlled intervention trial, with measurements before and after the intervention, 334 sex workers and 20 madams were recruited from an intervention site, and 207 and 17, respectively, from a similar control site, both in red-light areas of Bombay. All sex workers were tested for antibodies to HIV and syphilis, and for hepatitis B surface antigen. Information on sexual practices, condom use and knowledge of HIV was collected by interviewer-administered questionnaire. All subjects in the intervention group underwent a 6-month program of educational videos, small group discussions and pictorial educational materials; free condoms were also distributed. The blood tests and the questionnaire were readministered to all subjects at both sites immediately after the intervention. Both groups were followed for approximately 1 year. RESULTS: The baseline level of knowledge about HIV and experience with condoms was extremely low among both sex workers and madams. The baseline prevalence of HIV antibodies was 47% in the intervention group and 41% in the control group (P = 0.17). The incidence densities for HIV and sexually transmitted diseases were significantly different in the two groups (all P < 0.005): 0.05 and 0.16 per person-year of follow-up for HIV, 0.08 and 0.22 per person-year for antibodies to syphilis, and 0.04 and 0.12 per person-year for hepatitis B surface antigen in the intervention and control women, respectively. Following the intervention, women reported increased levels of condom use, and some (41%) said they were willing to refuse clients who wouldn't use them. However, both the sex workers and the madams were concerned about losing business if condom use was insisted upon. CONCLUSIONS: Both HIV prevalence and incidence are alarmingly high among female sex workers in Bombay. Successful interventions can be developed for these women, and even a partial increase in condom use may decrease the transmission of HIV and sexually transmitted diseases. Intervention programs of longer duration that target madams and clients and make condoms easily available are urgently needed at multiple sites in red-light areas.

PIP: The objective was to develop and test an HIV intervention targeting sex workers and madams in the brothels of Bombay. In a controlled intervention trial, with measurements before and after the intervention, 334 sex workers and 20 madams were recruited from an intervention site, and 207 and 17, respectively, from a similar control site, both in red-light areas of Bombay. All sex workers were tested for antibodies to HIV and syphilis, and for hepatitis B surface antigen. Information on sexual practices, condom use, and knowledge of HIV was collected by questionnaires. All subjects in the intervention group underwent a 6-month program of educational videos, small group discussions and pictorial educational materials; free condoms were also distributed. The blood tests and the questionnaire were readministered to all subjects at both sites immediately after the intervention. Both groups were followed for approximately 1 year. The baseline prevalence of HIV antibodies was 47% in the intervention group and 41% in the control group (p = 0.17). The incidence densities for HIV and sexually transmitted diseases were significantly different in the 2 groups (all p 0.005): 0.05 and 0.16 per person-year of follow-up for HIV, 0.08 and 0.22 per person-year for antibodies to syphilis, and 0.04 and 0.12 per person-year for hepatitis B surface antigen in the intervention and control women, respectively. Following the intervention, there was a significant increase in knowledge of modes of HIV transmission in the intervention group (n = 334) compared to the control group (n = 190) (60% vs. 99% compared to 56% vs. 26%, p 0.001). In addition, women reported increased levels of condom use and some (41%) said they were willing to refuse clients who would not use them. However, both the sex workers and 100% of the madams were concerned about losing business if condom use was insisted upon. Intervention programs of longer duration that target madams and clients and make condoms easily available are urgently needed.

Behavioral factors in the spread of HIV infection.

PIP: Evidence that behavioral factors affect the spread of HIV infection, both direct and by implication from high-risk behavior in general, and a model for further research and intervention are reviewed. Measurement of prevalence of high-risk behaviors over time is essential to see whether risk is increasing or decreasing in populations. There is good evidence that AIDS education programs have controlled HIV spread among homosexual and bisexual men in San Francisco, judging by both HIV seroprevalence and that of gonococcal proctitis. These educational interventions virtually saturated the area. Other populations have failed to respond to AIDS education, particularly teens, young adults, poor, non-white, less educated, and people from other areas. 39% of AIDS cases in the U.S. are from minority groups; 50% are Black and 24% are Hispanic. Currently homosexual men living outside a gay community, those without social ties and bisexual men are still showing increasing HIV infections, while homosexual men in open, active communities have decreasing rates. Other risk-behaviors associated with HIV infection include use of drugs, alcohol, tobacco, and having sex outside of "relationships." Conditions correlated with safe behaviors included knowing of one's positive HIV status, possessing skills of safe sex, perceiving one's risk accurately, and having peer support. Peer support is extremely influential, and includes general social support, peer expectations and support for behavior change, and capability to seek help when needed. A detailed AIDS risk reduction model is proposed and described.^ieng

Rapid HIV testing and counseling for voluntary testing centers in Africa.

OBJECTIVE: Voluntary HIV testing and counseling (VTC) has been shown to reduce the incidence of HIV in cohabiting couples who now represent the majority of new infections in many African cities. Community and client perceptions of a 1-day voluntary testing and counseling program in Lusaka, Zambia, were assessed, and a rapid HIV-testing algorithm was evaluated for VTC centers. METHODS AND DESIGN: Between May 1995 and June 1996, outreach workers distributed written invitations door to door. The 1-day program was held 6 days/week including weekends. Transport, child care and lunch were provided. Community and client surveys followed in July 1996. RESULTS: Over 3500 couples married for a median of 4-5 years requested testing: 23% were HIV+/+, 57% were HIV-/- and 20% were discordant with one HIV+ and one HIV- partner. Sixty-eight per cent of couples surveyed had made the decision to be tested before attending the 1-day program and 80% had not previously known where to obtain HIV testing. Knowledge that couples could show discordant results rose from 29 before to 88% after pretest counseling. Clients reported high levels of satisfaction with the services and 90 out of 99 (92%) preferred to receive their results the same day. Clients at another center who waited 10 days for their results reported more fear, and 19 out of 31 (61%) would have preferred to get their results the same day. Over 99% of those who attended the program thought active promotion of voluntary HIV testing in the community was a positive thing, as did 90% of those who were invited but did not attend. Sensitivity and specificity of the rapid test algorithm were both 99.4% in this setting. CONCLUSIONS: Active promotion of voluntary HIV testing and counseling in couples is needed to reduce the spread of HIV in high-prevalence areas. The use of rapid, on-site HIV testing allows clients to receive result-specific counseling in a single visit. Ongoing quality control of a subset of samples at an outside laboratory is essential.

PIP: Voluntary, confidential HIV testing and counseling centers (VTCs) are becoming increasingly popular in African cities with high HIV prevalence. This strategy is especially effective among HIV-discordant couples. During a 12-month period during 1995-96, community outreach workers distributed written invitations to attend a VTC in Lusaka, Zambia, in which couples would receive testing and result-specific counseling in a single visit; transportation, child care, and lunch were offered. Over 3500 couples, one-third of those invited, responded to the invitation and underwent rapid HIV testing. The Dipstick HIV-1 + 2 rapid test was used for screening and the Capillus HIV-1/HIV-2 rapid test was employed for confirmation. Both partners were HIV-positive in 23% of cases and both were HIV-negative in 57%; in the remaining 20% of couples, 1 partner was HIV-positive and the other was uninfected. 68% of participating couples had decided to seek HIV testing before receiving notice of the VTC, but 80% of them did not know where to obtain such services. Couples who attended the VTC that offered same-day test results reported substantially less fear than those who had to wait 10 days for their results. 99% of those who participated in the program thought active community promotion of VTC was desirable, as did 90% of those who were invited but did not attend. The rapid test algorithm had both a sensitivity and specificity of 99.4%. Continued retesting of a subset of samples at an outside laboratory remains essential, however. This intervention is associated with an estimated cost of US $84 per HIV infection prevented.

Traditional Balinese youth groups as a venue for prevention of AIDS and other sexually transmitted diseases.

OBJECTIVES: Our aims were to assess the feasibility of conducting peer-led educational interventions against AIDS and other sexually transmitted diseases (STDs) through traditional Balinese youth groups and to gather information on sexual risk-taking and its correlates among Balinese youth. DESIGN: A cross-sectional survey was conducted, with follow-up questionnaires for pilot intervention participants. SUBJECTS AND METHODS: A self-administered questionnaire was given to 375 subjects (aged 16-25 years) from 12 youth groups representing four main resort areas in Bali. Post-intervention data were collected from 97 of these subjects who had taken part in pilot educational programs. Focus groups supplemented survey data in evaluating the intervention and understanding risk behaviors. RESULTS: In a cross-sectional survey, one-quarter of males and few females reported sexual activity; subsequent focus groups suggested under-reporting by females. While knowledge and worries about HIV/AIDS were high, only 10% of sexually active males and no females reported consistent condom use. The mean age of first sexual intercourse was highly correlated with first alcohol consumption (P = 0.0003). Peer educators from selected youth groups planned and implemented interventions for their own groups. Post-intervention data indicated significant increases in communication about sexual issues with friends and parents. Condom attitudes became less negative and efficacy increased. Participants reported this as a first experience with peer-led health education, preferred interactive activities to adult-led lectures and recommended follow-up educational sessions. CONCLUSIONS: Peer educators from traditional youth groups can plan and conduct prevention programs for HIV/STDs that are well-received by their group memberships. Using such venues may be an efficient way to reach a wide range of pre-sexual Balinese youth, as well as those already at risk for HIV/STD due to unprotected sex, alcohol consumption and multiple sexual partners.

PIP: In a 1995 survey of Balinese youth, 75% expressed a desire to discuss sexual issues and AIDS/sexually transmitted diseases (STDs) with their peers. A cross-sectional survey of 375 young people 16-25 years of age assessed the feasibility of using traditional Balinese youth groups as a vehicle for peer-led AIDS education. In Bali virtually all youth, regardless of educational level or socioeconomic status, join the youth group in their neighborhood at puberty and remain members until they marry. The average age at first intercourse reported in the baseline survey was 18.8 years for males and 20.0 years for females. For 46% of sexually active males, intercourse was accompanied by alcohol consumption. Although youth had adequate knowledge of AIDS before the intervention, only 10% of sexually active males reported consistent condom use. Follow-up interviews with 97 young people from 3 resort areas of Bali who were exposed to the peer-led intervention revealed significant increases in communication about sexual matters with friends and family, more positive attitudes toward condoms, and increased condom use. Exposed youth who participated in focus group discussions expressed a preference for peer-led interactive activities over lectures and indicated they felt more comfortable asking their peers questions about sex. Use of peer educators from Balinese youth groups appears to represent an efficient way to reach young people before the initiation of sexual activity as well as those at high risk of AIDS and other STDs as a result of unprotected sex, alcohol consumption, and multiple sexual partners.

HIV risk behavioral surveillance in Bangkok, Thailand: sexual behavior trends among eight population groups.

OBJECTIVE: To assess trends in HIV risk behaviors over a 3-year period in eight population groups in Bangkok, Thailand. DESIGN AND SUBJECTS: Using a repeated cross-sectional survey design with a structured questionnaire, we collected five sets of self-reported sexual behavior data related to HIV risk from the following subject groups at the same sampling sites during 1993-1996: direct and indirect female sex workers, male attenders of sexually transmitted disease (STD) clinics, female attenders of antenatal care clinics, male and female vocational students, and male and female factory workers. RESULTS: Reported patronage of commercial sex by the three male groups declined by an overall average of 48% over the 3-year period. Other non-regular sexual partnerships declined among male STD clinic attenders and vocational students. Condom use during most recent sexual intercourse between sex workers and clients peaked at high levels (>90%) in the early data waves, while among indirect sex workers and their clients, consistent condom usage increased from 56% to 89%. Low condom use persisted among sex workers and their non-paying sex partners. Single women reported low levels of sexual activity and condom use with no signs of an increase. Similarly, married women from antenatal clinics reported low condom use with their husbands, with no change throughout the period of the study. CONCLUSIONS: HIV risk behavioral surveillance is a useful way of determining whether behavior change has occurred in specific population groups. The results here confirm and add to a growing set of evidence of risk behavior reduction in Thailand. The behavioral changes did not occur uniformly but varied depending on the sexual dyad and the population group under study. Behavioral surveillance should be promoted and its methodologies strengthened in attempts to understand the local dynamics of HIV epidemics.

AIDS education for primary school children in Tanzania: an evaluation study.

OBJECTIVE: To test the effects of an HIV/AIDS education program. DESIGN: A quasi-experimental, nested cross-sectional design including baseline and 6-month follow-up surveys. Schools, stratified according to location, were randomly assigned to intervention (n = 6) or comparison conditions (n = 12). SETTING: Public primary schools in Arusha and Kilimanjaro regions, Tanzania. PARTICIPANTS: A total of 2026 sixth and seventh grade pupils (average age, 14.0 years) participated at baseline (85%) and 1785 at follow-up. INTERVENTION: The program was designed to reduce children's risk of HIV infection and to improve their tolerance of and care for people with AIDS. Local teachers and health workers attended a 1-week training workshop before implementing the program over a 2-3-month period (averaging 20 school hours per class). MAIN OUTCOME MEASURES: Self-reported exposure to AIDS information, communication regarding AIDS; AIDS knowledge, attitudes towards people with AIDS, attitudes towards having sexual intercourse, subjective norms regarding sexual intercourse, and intention to engage in sexual intercourse. RESULTS: Following this program, intervention pupils reported significantly higher scores for the following outcome measures than pupils attending the comparison schools: AIDS information (13.1 versus 10.5; P = 0.0001), AIDS communication (10.9 versus 7.8; P = 0.0001) AIDS knowledge (14.5 versus 11.5; P = 0.0001), attitudes towards people with AIDS (9.0 versus 6.7; P = 0.0008), subjective norms (45.5 versus 43.9; P = 0.011), and intention (1.3 versus 1.4; P = 0.020). No program effect was seen for attitudes towards sexual intercourse (47.0 versus 46.3, P = 0.44). CONCLUSIONS: These results indicate that it is feasible and effective to provide AIDS education for Tanzanian primary school children.

PIP: In the adjacent regions of Arusha and Kilimanjaro in Tanzania, researchers conducted a quasi-experimental, nested cross-sectional design to evaluate the Ngao (shield) HIV/AIDS education program for public primary school children, a culturally specific program. The baseline survey and the 6-month follow-up survey included 2026 and 1785 6th-7th grade children, respectively. Teachers of the participating schools and health workers participated in a 1-week training workshop before they implemented the program over 2-3 months. Its intent was to reduce the pupils' risk of HIV infection and to improve their acceptance of and care for people with AIDS. At baseline, the pupils in intervention and comparison schools tended to be comparable. At follow-up, however, intervention pupils had been exposed to more AIDS information (scores, 13.1 vs. 10.5), had discussed AIDS more often (10.9 vs. 7.8), and had a higher increase in AIDS knowledge (14.5 vs. 11.5) than did the comparison pupils (p = .0001 for all the above). They also had significantly more positive attitudes towards people with AIDS than the comparison pupils (9 vs. 6.7; p = .0008). Pupils in the intervention had more restrictive subjective norms regarding sexual intercourse (45.5 vs. 43.8; p = .011) and less intention to engage in sexual intercourse over the next 3 months than at baseline. Yet, they were not significantly different from comparison pupils, because the comparison pupils also had a change in attitude. These findings show that teachers in primary schools and health educators can implement a workable and effective HIV/AIDS education program for school children.

A cohort study of factors associated with failure to return for HIV post-test counselling in pregnant women: Kigali, Rwanda, 1992-1993.

OBJECTIVE: To identify factors associated with failure to return for HIV post-test counselling in pregnant women in Kigali (Rwanda). SUBJECTS AND METHODS: In the context of a study on the impact of HIV infection on pregnancy, HIV-1-antibody testing was offered to all pregnant women attending the antenatal clinic of the Centre Hospitalier de Kigali from July 1992 to August 1993. Pre-test counselling was performed after verbal informed consent was obtained. Two weeks later, we formally enrolled all HIV-positive women and a corresponding number of HIV-negative women in a cohort. At this visit, post-test counselling was given to those wishing to be informed of their HIV serostatus. Level of knowledge about modes of HIV transmission and condom use were recorded. Four months after delivery, another interview was conducted to determine the proportion of women who used condoms regularly. RESULTS: A total of 1233 pregnant women were screened. The HIV seroprevalence was 34.4% [95% confidence interval (CI), 31.7-37.1]; 271 (63.9%) out of 424 HIV-positive and 577 (71.3%) out of 809 HIV-negative women asked for their HIV serostatus (P = 0.008). In multivariate analysis, the only variable significantly associated with failure to return for post-test counselling was a positive HIV test result (odds ratio, 0.7; 95% CI, 0.5-0.9; P = 0.009), independently of obstetrical history and socioeconomic characteristics. Among the 848 women who had post-test counselling, 50.9% of the HIV-positive women and 94.6% of the HIV-negative women stated that they planned to inform their partner of their serostatus (P = 0.0001). More than 95% of the women interviewed knew about sexual and parenteral transmission of HIV, but half were unaware of mother-to-child transmission. More than 80% of the women had seen a condom before, but 14% only had used it at least once. Among women who were sexually active 4 months after delivery, 8.8% of the HIV-positive and 3.9% of the HIV-negative women reported using a condom (P = 0.04). CONCLUSION: Innovative approaches for HIV testing and counselling programs are needed and the importance of psychosocial and cultural factors associated with HIV testing should be emphasized in African populations.

The efficacy of brief group counseling in HIV risk reduction among homosexual Asian and Pacific Islander men.

OBJECTIVES: The incidence of AIDS is increasing at a higher rate among homosexual Asian and Pacific Islanders (API) than white homosexual men in the United States. The number of homosexual API men engaging in unsafe sex is increasing at an alarming rate. HIV risk reduction is urgently needed in this population. SUBJECTS AND METHODS: We developed and evaluated culturally appropriate brief group counseling with 329 self-identified homosexual API recruited in San Francisco between 1992 and 1994. Participants were randomized into a single, 3-h skills training group or a wait-list control group. The intervention consisted of four components: (1) development of positive self-identity and social support, (2) safer sex education, (3) eroticizing safer sex, and (4) negotiating safer sex. Data were collected at baseline and 3 months after the intervention. RESULTS: Significant reductions in number of sexual partners were observed among all treatment subjects, regardless of ethnicity (P = 0.003). Treatment decreased the number of partners reported at 3-month follow-up by 46% [95% confidence interval (CI), 28-77]. Chinese and Filipino men further benefited from the intervention: treatment subjects from these two ethnic groups reduced unprotected anal intercourse at follow-up by more than half when compared to their counterparts (odds ratio = 0.41; 95% CI, 0.19-0.89; P = 0.024). CONCLUSIONS: We demonstrated the efficacy of brief group counseling in reducing HIV risk among homosexual API. Cities with significant API populations should adopt culturally tailored skills training as part of HIV prevention strategies for this group of homosexual men.

The effects of post-test counselling on condom use among prostitutes in The Gambia.

OBJECTIVES: To determine the effect of counselling on condom use by prostitutes. DESIGN: Cohort study. SETTING: Field-based study in The Gambia. PARTICIPANTS: Thirty-one (12 HIV-positive and 19 HIV-negative) prostitutes. INTERVENTIONS: Post-test HIV counselling. MAIN OUTCOME MEASURES: Levels of condom use. RESULTS: Overall, counselling had no effect on condom use. CONCLUSIONS: Scarce resources should be directed towards providing condoms in bars rather than counselling.

PIP: HIV infection is much more prevalent in prostitution than in the general population of the Gambia (26.2 vs. 1.7%, respectively, in 1988). The short-and long-term effects of counseling on condom use by prostitutes was examined by determining condom use in 29 prostitutes, 11 HIV-positive (group 1) and 18 HIV-negative (group 2), before and 1 month after counseling and in 31 prostitutes, 12 HIV-positive group 3) and 19 HIV-negative (group 4), before and 2-5 month after counseling. HIV-positive women were told that reinfection would increase their chances of developing AIDS as well as lead to transmission of the virus. 3515 sexual contacts were recorded before counseling, 1252 after 1 month, and 4949 at 2-5 months later. Group 1 women reported an 89.3% rate of use before counseling; 1 month later, 9 maintained their rate, 1 increased use from 56 to 81%, and 1 decreased use from 31 to 26%. Group 2 women had 88% use before and, in 11 of the 12 women, 90% use after counseling; the 12th woman reduced use to 66% and was observed to increase her alcohol intake significantly. In both groups, 4 increased use and 3 reduced use. In Group 3, condom use declined insignificantly from 89.3 to 83.5%. 4 women maintained 90% use, 6 reduced use, and 2 increased it. Group 4 women decreased use insignificantly from 88% before to 84.4% after counseling. 8 women maintained original levels of use, 4 increased, and 7 decreased (1 from 90% to as low as 17%). In groups 3 and 4, 74% had 90% use precounseling; this fell to 69% at 1 month and 36% at 2-5 months after counseling, a significant decrease in usage. In all of the prostitutes, condom use increased in the first month after counseling and fell 2-5 months later. Counseling, therefore, failed to increase overall condom use. Possible reasons for this failure include the Senegalese backgrounds of many of the women (they were accustomed to health checks and free condoms); the low number of AIDS deaths in the Gambia, which keeps the disease a distant possibility instead of a pressing reality for the prostitutes; and the consideration of condom use as primarily a method to prevent contraction of the traditional sexually transmitted diseases. When resources are scarce, it may be more important to provide free condoms in bars frequented by prostitutes than to provide counseling.

Knowledge, attitudes and behaviour among HIV-positive and HIV-negative clients of a confidential HIV counselling and testing centre in Thailand.

OBJECTIVE: To describe the clients, operation and impact of an Asian public HIV counselling and testing centre. DESIGN AND SETTING: Analysis of samples from clients attending the Thai Red Cross Anonymous Clinic (TRC-AC) in Bangkok, Thailand in 1993. SUBJECTS: HIV-positive and HIV-negative consecutive clients (250 of each). MAIN OUTCOME MEASURES: HIV seroprevalence rates, knowledge, attitudes and behaviour. RESULTS: Overall HIV-1 prevalence was 16%; 13% in men and 24% in women. Reasons for requesting an HIV test were high-risk behaviour (21%), feeling unwell (20%), checking a previous HIV test result (18%), a planned marriage or new relationship (10%), and planning a baby (5%). Heterosexual risk behaviour was reported by 85% of clients, while in each case only 1% reported male homosexual or intravenous drug use risk behaviour. Factors associated with HIV infection on univariate analysis included a history of sexually transmitted disease, not using condoms, a low level of education and salary, and being female. Knowledge about HIV transmission risks and AIDS prevention measures was good, and most clients expressed a caring attitude towards people with HIV and AIDS. A former negative HIV test result was associated with higher levels of condom use, and most clients expressed the intention to reduce their HIV risk behaviour in response to a positive or negative HIV test result (more so if positive). CONCLUSIONS: Our study demonstrates the demand for and the feasibility of confidential HIV counseling and testing services in Thailand and illustrates the value of these services in achieving behaviour changes. Such services should be considered as an additional approach for reducing HIV transmission in Asia, especially in areas with high HIV seroprevalence rates.

PIP: Data are presented from HIV serodiagnoses and knowledge, attitude, and behavior questionnaire responses for 250 HIV-positive and 250 HIV-negative consecutive clients attending the Thai Red Cross Anonymous Clinic in Bangkok, Thailand in 1993. The study was conducted to describe the clients, operation, and impact of the public HIV counseling and testing center. The men and women were of mean age 26-29 years in a range of 16-64 years. 16% overall were HIV-1-seropositive; 13% of men and 24% of women. 21% requested the HIV test in response to previous high-risk behavior, 20% felt sick, 18% were checking a previous HIV test result, 10% planned marriage or a new relationship, and 5% planned to have a baby. Heterosexual risk behavior was reported by 85% of clients, but only 1% reported male homosexual or IV drug use risk behavior. These behaviors were reported despite the existence among the sample of ample information about HIV transmission risks and AIDS prevention measures. An history of sexually transmitted disease, not using condoms, low education and salary levels, and being female were associated with HIV infection. Former negative HIV test results were associated with higher levels of condom use, while most clients expressed the intention to reduce their HIV risk behavior in response to either a positive or negative HIV test result. Most clients had caring attitudes toward people with HIV and AIDS. The authors note that sufficient demand exists for confidential HIV counseling and testing services in Thailand. Such services should be considered as a means of reducing HIV transmission in Asia, especially in areas of high HIV seroprevalence.

Care of children with HIV infection and AIDS in Africa.

PIP: HIV/AIDS is a major cause of pediatric morbidity and mortality, especially in Africa. The UN Joint Program on HIV/AIDS (UNAIDS) estimates that 85% of the 2.6 million children with HIV infection are from sub-Saharan Africa. About 650,000 children are living with HIV/AIDS and approximately 1000 infected infants are born every day in Africa. Since few of the 7 million infected African women have access to HIV testing and counseling, not to mention interventions such as AZT to reduce the risk of HIV transmission to their infants, the high incidence of HIV-infected children in Africa will likely continue for some time. The countries of east and southern Africa and several countries in west Africa have the highest HIV prevalence rates in the world. The development of cost-effective strategies to provide care and improve the quality of life of HIV-infected infants and children in Africa should be a priority area for increased research and support. The authors describe progress in understanding the natural history of HIV infection in African children, review strategies for managing HIV-infected children in resource-poor settings, and discuss issues of community response and counseling for children.^ieng
