RESUMO

The slogan Undetectable equals Untransmittable (U = U) communicates that people living with HIV (PLHIV) who are on antiretroviral therapy (ART) will not transmit HIV to their sexual partners. We describe awareness of U = U among sexual and gender minorities (SGM) living in Brazil, Mexico, and Peru by self-reported HIV status (PLHIV, negative, unknown) during 2021 using an online survey. We estimated two models using Poisson regression for each population group: Model A including socio-demographic factors (country, gender, age, race, education, and income), and then Model B including taking ART (for PLHIV) or risk behavior, ever-taking PrEP, and HIV risk perception (for HIV-negative or of unknown HIV status). A total of 21,590 respondents were included (Brazil: 61%, Mexico: 30%, Peru: 9%). Among HIV-negative (74%) and unknown status (12%), 13% ever used PrEP. Among PLHIV (13%), 93% reported current use of ART. Awareness of U = U was 89% in both Brazil and Mexico, which was higher than in Peru 64%. Awareness of U = U was higher among PLHIV (96%) than HIV-negative (88%) and HIV-unknown (70%). In multivariate models, PLHIV with lower education were less aware of U = U, while those taking ART were more aware. Among HIV-negative, non-cisgender, lower income, and those with lower education had lower awareness of U = U, while individuals ever using PrEP had higher awareness. In conclusion, awareness of U = U varied by HIV status, socio-demographic characteristics, and HIV risk behavior. The concept of U = U should be disseminated through educational strategies and include a focus on SGM to combat HIV stigma.


RESUMEN: Indetectable = Intransmisible (I = I) comunica que las personas que viven con VIH (PVVIH) y reciben tratamiento antirretroviral (TAR) no transmitirán el VIH a sus parejas sexuales. En este estudio, describimos la concienciación sobre I = I entre las minorías sexuales y de género (MSG) de Brasil, México y Perú según el estado de VIH autoreportado (PVVIH, negativo, desconocido) durante 2021 utilizando una encuesta en línea. Se estimaron dos modelos mediante regresión de Poisson para cada grupo: Modelo A, que incluyó factores sociodemográficos (país, sexo, edad, raza, educación e ingresos) y Modelo B, que incluyó recibir TAR (para PVVIH) o comportamiento de riesgo, uso de PrEP y percepción de riesgo (para VIH negativo o desconocido). Se incluyó 21,590 encuestados (Brasil: 61%, México: 30%, Perú: 9%). Entre aquellos negativos para VIH (74%) y con estado desconocido (12%), el 13% utilizó alguna vez PrEP. Entre las PVVIH (13%), el 93% reportó recibir actualmente TAR. La concienciación de I = I fue del 89% tanto en Brasil como en México, superior al 64% de Perú. La concienciación de I = I fue mayor entre PVVIH (96%) que entre los VIH-negativos (88%) y los VIH-desconocidos (70%). En los modelos multivariados, las PVVIH con menor educación eran menos conscientes de I = I, mientras que los que tomaban TAR eran más conscientes. Entre los VIH-negativos, las personas no cisgéneros, con menores ingresos y con menor educación eran menos consciente de I = I, mientras que los que tenían experiencia usando PrEP eran más conscientes. En conclusión, la concienciación sobre I = I varió según el estado serológico de VIH, las características sociodemográficas y el comportamiento de riesgo. El concepto de I = I debe difundirse a través de estrategias educativas, incluyendo un enfoque en MSG para combatir el estigma del VIH.

RESUMO

BACKGROUND: Current syphilis tests cannot distinguish between active and past syphilis among patients with serofast rapid plasma reagin (RPR) titers. We investigated whether cytokine profiles might provide insight in the differentiation of active and treated syphilis. METHODS: We collected quarterly serum samples from participants at risk for incident syphilis in a prospective cohort study of men and male-to-female transgender women. We defined incident syphilis as a new RPR titer ≥ 1:8 or a fourfold increase from a prior RPR titer and a positive Treponema pallidum particle agglutination assay. We measured cytokine expression using a 63-multiplex bead-based Luminex assay (eBiosciences/Affymetrix, San Diego, California, USA). We used tertile bins and Chi square tests to identify differences in proportions of cytokines between samples from patients with active and treated syphilis. We constructed a network of cytokine profiles from those findings. We used R software (R version 3.4.1, R, Vienna, Austria) to fit models. RESULTS: We identified 20 pairs of cytokines (out of 1953 possible pairs) that differed between active and treated syphilis. From those, we identified three cytokine networks of interest: an Eotaxin-Rantes-Leptin network, a Mig-IL1ra-Trail-CD40L network, and an IL12p40-IL12p70 network. CONCLUSIONS: Differences in cytokine profiles are present among men and male-to-female transgender women with active and treated syphilis. Cytokine assays may be a potentially useful tool for identifying active syphilis among patients with serologic syphilis reactivity.

RESUMO

HIV infections in Peru are concentrated among men who have sex with men (MSM) and transgender women (TW). HIV testing rates among them remain low, delaying entrance into care. We assessed the prevalence of frequent HIV testing (at least every 6 months) and associated factors among 310 MSM and TW who attend sexual health clinics in Lima, Peru, and who reported that they were HIV seronegative or unaware of their status. Only 39% of participants tested frequently, and 22% had never tested; 29% reported that they were at low or no risk for acquiring HIV. Reporting low or no risk for acquiring HIV was associated with frequent testing (adjusted prevalence ratio [aPR] = 1.53, 95% CI 1.13-2.08); those reporting unprotected anal sex were less likely to test frequently (aPR = 0.66, 95% CI 0.50-0.87). HIV prevalence was 12% and did not vary by risk perception categories. This at-risk population tests infrequently and may not understand the risk of having unprotected sex.

RESUMO

Alcohol abuse can influence sexual risk behavior; however, its measurement is not straightforward. This study compared self-reported alcohol use, via the AUDIT and CAGE, with levels of phosphatidylethanol (Peth), a phospholipid biomarker that forms with chronic, heavy drinking, among high-risk MSM and TW in Lima, Peru. Chi square, Fisher's exact, Wilcoxon ranksum tests compared the instruments. Receiver operating curves determined sensitivity and specificity of the self-reported measures. Among 69 MSM and 17 TW, PEth was positive for 86% (95% CI 77-93%) of participants, while 67% reported binge-drinking in the last 2 weeks. The AUDIT classified 25% as hazardous drinkers while CAGE identified 6% as problem drinkers. Self-reported binge drinking was more sensitive than the AUDIT for PEth positivity (71% vs. 27%, p = 0.022). Among high-risk MSM and TW in Lima, validated, self-report measures of alcohol abuse underestimated biological measures. Further research correlating bio-markers and self-reported alcohol abuse measures is needed.

RESUMO

We assessed the laboratory performance of the Chembio dual-path platform HIV-syphilis rapid immunodiagnostic test and electronic reader for detection of HIV and Treponema pallidum antibodies in 450 previously characterized serum specimens. For visual or electronic reader HIV antibody detection, the sensitivity was 100% and the specificity was 98.7%. For visual T. pallidum antibody detection, the test sensitivity was 94.7% and the specificity was 100.0%; with the electronic reader, the sensitivity was 94.7% and the specificity was 99.7%.

RESUMO

Combining the detection of syphilis and HIV antibodies into one point-of-care test integrates syphilis screening into already existing HIV screening programs, which may be particularly beneficial in settings such as antenatal care. Using the INSTI Multiplex downward-flow immunoassay, we tested 200 stored serum samples from high-risk patients enrolled in a longitudinal study on HIV infection and syphilis in Peruvian men who have sex with men and transgender women. This rapid assay detected HIV and Treponema pallidum serum antibodies with sensitivities of 100% (95% confidence interval [CI], 95.9% to 100%) and 87.4% (95% CI, 81.4% to 92.0%), respectively, and specificities of 95.5% (95% CI, 89.9% to 98.5%) and 97.0% (95% CI, 84.2% to 99.9%), respectively (n = 200). The sensitivity for syphilis antibody detection was higher in patients with a rapid plasma reagin titer of ≥1:8 (97.3%) than in those with a titer of ≤1:4 (90%) or a nonreactive titer (66.7%).

RESUMO

OBJECTIVES: To conduct a systematic review of published and unpublished data from research and public health information systems on the prevalence of male-to-male sex in the total male population; as well as among men who have sex with men (MSM), data on prevalence of heterosexual activity and heterosexual unions; prevalence of condom use with male and female partners; and prevalence of HIV infection and other sexually transmitted infections (STIs). METHODS: Key indicators were defined (a) among men in the general population: prevalence of sex with a man ever and last year; (b) among MSM: prevalence of heterosexual experiences ever and last year; proportion of male-female transgenders; proportion of sex workers; prevalence of HIV and other STIs, condom use in last sexual encounter; consistent condom use with men last year; never used a condom with a man. With help from key informants, study searches were conducted in Pubmed, LILLACS, institutional databases, conference records and other sources. Methodology and quality of information were assessed, and the best data available for 2003-7 were selected. Indicator estimates from each study were used to propose regional estimate ranges. RESULTS: A total of 83 new entries were entered into the database in addition to the previous 561, totalling 644. Of these, 107 showing 2003-7 data were selected. Many new studies came from sub-Saharan Africa, portraying hidden HIV epidemics among MSM. The most frequently reported estimate was HIV infection, with high estimate ranges in most of the regions, except for Middle East and North Africa and Eastern Europe. The next most frequently reported was lifetime frequency of heterosexual sex, showing that roughly 50% of MSM ever had sex with a woman. The small number of newer studies reporting prevalence of "sex with a man in last 12 months" between 2003 and 2007, did not warrant enough new evidence to revise our 2005 size estimates for MSM populations. CONCLUSIONS: A considerable number of new studies with estimates of relevance to understanding sexual behaviour and HIV among MSM were identified, with an encouraging amount of new data coming from sub-Saharan Africa. However, limitations in the quality, utility and comparability of available information persist. At least three measures could be promoted for use in surveillance and academic studies: standardised indicators for MSM studies; standardised operational definitions of, and instructions to describe, variables; and standardised research designs and data gathering strategies. A prerequisite for this all is intense advocacy to ensure a social climate in which research into such matters is prioritised, resources are made available as needed and the human rights of MSM are respected.

RESUMO

OBJECTIVES: To assess the prevalence of sexually transmitted infections (STIs), the frequency of sexual risk behaviours, and the relation between knowledge of HIV infection status and sexual risk behaviour among men who have sex with men (MSM) infected with HIV attending an STI clinic in Peru. METHODS: We recruited a convenience sample of 559 MSM from a municipal STI clinic in Lima, Peru. Participants completed a survey and provided blood for HIV, syphilis and HSV-2 antibody testing, and urine for gonorrhoea and chlamydia nucleic acid testing. RESULTS: Among 124 MSM with HIV, 72.6% were aware that they were infected with HIV. Active syphilis (RPR> or =1:8) was diagnosed in 21.0% of men infected with HIV, HSV-2 in 79.8%, urethral gonorrhoea in 1.6% and chlamydia in 1.6%. Among 41 participants reporting insertive anal intercourse with their last sex partner, 34.2% did not use a condom. Of the 86 participants reporting receptive anal intercourse, 25.6% did not use a condom. At least one episode of insertive unprotected anal intercourse (UAI) with a partner uninfected with HIV during the past 6 months was reported by 33.6% (35/104) of participants, and receptive UAI with a partner uninfected by HIV was reported by 44.6% (45/101). There was no difference in frequency of UAI with partners infected or uninfected with HIV observed between men who knew their serostatus compared with those who were previously undiagnosed (all p values >0.05). CONCLUSIONS: MSM with HIV in Peru engaged in high-risk behaviours for spreading HIV and STIs. Knowledge of whether someone was infected with HIV was not associated with a decreased frequency of UAI. Additional efforts to reduce risk behaviour after the diagnosis of HIV infection are necessary.

RESUMO

The goal of this study was to determine the prevalence of bacterial vaginosis (BV) in Peruvian women from socioeconomically deprived populations and to determine the association between BV and risk factors for sexually transmitted diseases (STDs). Women were administered an epidemiologic survey to determine sexual risk behaviour and they provided biological samples to test for BV and STDs. The prevalence of BV was high (27%) and was significantly associated with having a bacterial STD or trichomoniasis. Age, marital status, and a history of sex work, but not of sexual experience, frequency of intercourse, and unprotected intercourse, were associated with BV. As BV may be a marker for STDs, screening for STDs should be performed in individuals with BV to promote early detection and treatment of co-infecting sexually transmitted pathogens.

RESUMO

BACKGROUND: Alcohol use disorders (AUDs) may enhance the likelihood of risky sexual behaviors and the acquisition of sexually transmitted infections (STIs). Associations between AUDs with condomless anal intercourse (CAI) and STI/HIV prevalence were assessed among men who have sex with men (MSM) and transgender women (TW) in Lima, Peru. METHODS: MSM and TW were eligible to participate based on a set of inclusion criteria which characterized them as high-risk. Participants completed a bio-behavioral survey. An AUDIT score ≥8 determined AUD presence. Recent STI diagnosis included rectal gonorrhea/chlamydia, syphilis, and/or new HIV infection within 6 months. Prevalence ratios (PR) were calculated using Poisson regression. RESULTS: Among 312 MSM and 89 TW, 45% (181/401) had an AUD. Among those with an AUD, 164 (91%) were hazardous/harmful drinkers, and 17 (9%) had alcohol dependence. Higher CAI was reported by participants with an AUD vs. without, (82% vs. 72% albeit not significant). Reporting anal sex in two or more risky venues was associated with screening AUD positive vs. not (24% vs. 15%, p=0.001). There was no difference in recent STI/HIV prevalence by AUD status (32% overall). In multivariable analysis, screening AUD positive was not associated with CAI or recent STI/HIV infection. CONCLUSIONS: In our sample AUDs were not associated with CAI or new HIV infection/recent STI. However higher prevalence of CAI, alcohol use at last sex, and anal sex in risky venues among those with AUDs suggests that interventions to reduce the harms of alcohol should be aimed toward specific contexts.

RESUMO

OBJECTIVE: To describe sexual behavior patterns and identify psychosocial and situational correlates of safer practices among men who have sex with other men in Lima. DESIGN: A cross-sectional survey. SUBJECTS AND METHODS: In 1992, 223 mostly young, working- and middle-class homosexually active men in Lima, who reported either being seronegative or not knowing their HIV status, were recruited from public places, gay organizations and through snowballing techniques. Measurements included patterns of sexual behavior and socialization with other homosexually active men, and psychosocial and situational factors. Three risk behavior indicators were used: the practice of unprotected receptive anal intercourse, the practice of unprotected anal intercourse (insertive or receptive) and an index of behavioral risk based on numbers of sexual partners for different risk practices. RESULTS: The subjects (mean age 24.9 years, SD 6.3) were mostly exclusively homosexual (74%) and self-identified as gay/homosexual (73%); 41% had had unprotected anal intercourse during the last 4 months (75% of them in the receptive role). Reporting sex in public places consistently predicted riskier behavior by any of the three indices, whereas a lower perception of benefits of condoms/safer sex, poor AIDS knowledge, participation in a steady relationship and higher self-efficacy were associated with one or two of the indices. CONCLUSIONS: Besides considering basic AIDS information and the promotion of condoms and safer sex, intervention programs for homosexually active men in Lima should emphasize the need for open discussions on safety in steady relationships, promote accurate perceptions of personal risk and sensitively address the special difficulties posed by sexual activity in public places.

RESUMO

OBJECTIVES: To review current approaches to HIV surveillance among men who have sex with men (MSM), identify illustrative best practices and lessons learned, and outline ways to enhance surveillance systems. METHODS: Review of the literature and institutional guidelines for HIV/AIDS, sexually transmitted infection (STI), and behavioral surveillance and summary of results of an international workshop. RESULTS: On-going formative research, HIV/AIDS and STI case reporting, HIV prevalence and incidence studies, and behavioral surveys are essential components of an effective HIV surveillance system for MSM. Alliances with key organizations and actors in MSM communities provide points of access, assist in the development of measures, and guide appropriate use of data. Sampling techniques (convenience, snowball, quota, microsite, time-location, and population-based) offering a range of methods, complexity, and cost have been successfully implemented in MSM communities. Plausible estimates of the size of MSM populations, which are ultimately crucial to the interpretation of surveillance data, can be improved upon using primary and secondary data. CONCLUSIONS: The purpose of HIV surveillance among MSM is not only to monitor disease occurrence and its antecedents, but to regularly use data to plan and evaluate prevention and care programs, advocate for prevention resources, and improve the health, social welfare and human rights of MSM. Practical, incremental steps can be taken to improve HIV surveillance among MSM in all regions of the world in all stages of the epidemic.

RESUMO

OBJECTIVES: (1) To describe psychosocial variables related to sexual activity and the prevalence of contextual factors (e.g. coercion, paid sex and drug/alcohol use) and various sexual experiences among young men and women in Lima; and (2) to assess the relationship between psychosocial, contextual and behavioral factors on one hand and negative sexual health events such as unplanned pregnancies and sexually transmitted diseases (STDs) on the other hand. DESIGN: A cross-sectional serosurvey complemented with focus groups and in-depth interviews. SUBJECTS AND METHODS: A total of 611 adolescents (16-17 years old) and 607 young adults (19-30 years old) were recruited randomly from among those registering for military service (adolescents) or seeking work/study permits (young adults). These subjects were asked to fill out a self-administered questionnaire with detailed information on sexual experiences and psychosocial variables. The response rates were 98% (adolescents) and 82% (young adults). A subsample of 858 subjects provided blood specimens, which were analyzed for antibodies to HIV-1, the hepatitis B virus and syphilis. The relationship between the main study variables and sociodemographic indicators was also assessed, and multivariate analysis was used to identify those variables associated with sexual health problems. A preliminary qualitative phase helped in the questionnaire design and in interpreting survey findings. RESULTS: Thirty-four percent of adolescents and 75% of young adults were sexually experienced. The prevalence of bisexual behavior was high, particularly among males (12%). The males often reported paid sex (47%) and the females often reported sexual coercion (47%). Among the heterosexually active, only 11% reported consistent use of condoms. While 22% of the heterosexually active reported an unplanned pregnancy in self (females) or partner (males), 18% of the sexually active reported a history of STD symptoms or diagnoses. Among the sexually active who gave a blood sample, 0.2% were positive for HIV, 6.7% for hepatitis B and 1.5% for syphilis. Those who experienced an unplanned pregnancy or STD symptoms or, for the subsample, were seropositive for HIV or other STDs, were more likely to perceive social norms as restricting condom use to casual sex, to be older, to combine sex with alcohol or drugs and to report a history of sexual coercion or of having paid or been paid for sex. For females only, engaging in sex at a younger age was a risk marker, while engaging in any homosexual activity was protective. CONCLUSIONS: Cultural norms that restrict condoms to casual sex may place many young people in Lima at risk of an unplanned pregnancy or STDs. Sexual behavior may be especially risky in a context of sexual coercion and paid sex, when sex is combined with drugs and alcohol, and when engaged in by younger females. Sexual health education should work to change such cultural norms and these risky contexts.

RESUMO

PURPOSE: To determine the prevalence and correlates of sexual coercion in young adults in Lima, Peru. METHODS: Lifetime sexual coercion and that at first sexual experience were studied in 629 sexually active young people, drawn from representative samples of 611 adolescents and 607 young adults. RESULTS: Almost half of the young women and a quarter of the young men in the study reported sexual coercion. In multiple logistic regression analyses, men and women who reported having been coerced at heterosexual initiation also reported more lifetime sexually transmitted diseases and a lower age at first sex than those not reporting coercion. Men who reported coercion at heterosexual initiation also reported a lower number of lifetime heterosexual partners and less sexual knowledge than men not coerced. CONCLUSION: Experiencing heterosexual initiation as coercive appears to be a marker for a riskier sexual career for both genders and for future homosexual behavior in men.

RESUMO

PURPOSE: In a context of increasing HIV/STD risks among adolescents in Latin America, new conceptions of sequential "sex education" are needed. However, older adolescents must be reached through shorter programs. A quasi-experimental study was conducted to evaluate the impact of a short school-based STD/AIDS prevention program on knowledge, attitudes, and intended behavior among secondary students in Lima. METHODS: Aimed at empowering adolescents regarding their sexuality, improving knowledge and attitudes, and developing skills and prevention-oriented behavioral intentions, the program consisted of seven weekly two-hour sessions. Cost exclusive of research expenses was $3 per student reached. RESULTS: 1213 students from 14 schools participated in either the intervention or control groups. Significant changes in knowledge on sexuality and AIDS, erotophilia, acceptance of contraception, machismo, and discrimination against persons with HIV/AIDS were found in the intervention group, as compared to the control group. Self-efficacy and prevention-oriented behavioral intentions were significantly better in the intervention group. CONCLUSIONS: Owing to its effectiveness, acceptability, and low cost, this program may become useful in reaching adolescents unable to participate in longer-term sex education programs in Peru and elsewhere.

RESUMO

PIP: Between November 1989 and January 1990, a pilot study was conducted among state secondary school students and teachers in Lima Peru by questionnaires with the objective of determining their knowledge about human sexuality, sexual behavior, pregnancy, sexually transmitted diseases (STDs), AIDS, drug abuse, and sexual activity. 110 students (64 boys and 46 women) aged 13-18 of low and medium-low socioeconomic background from metropolitan Lima participated. 40 teachers (70% females) aged 40.1 + or - 9.3 years also took part. THe adolescent focus groups were anxious to talk openly about sexuality to dispel their doubts. The levels of knowledge reached 46% for human sexuality, 50% for physiology and pregnancy, 35% for STDs and preventive sexual behavior, 50-60% for AIDS (transmission and risk groups), and only 35% for prevention. 21 had heterosexual experiences: 19 males and 2 females. 6 youngsters had homosexual experiences: 4 males and 2 females, 3 of these also had heterosexual sex. 20 of students without sexual experience expressed on interest, in engaging in sexual behavior if they fell in love. 33 adolescents reported using alcohol, 1/4 of these had consumed more than 6 bottles the previous week. The report on drug use was low, because 32% failed to answer this question. 60-70% of the teachers knew about human sexuality, while 72% knew about AIDS. 76.5% of them considered sex education in schools inadequate. 88.2% thought that adolescents need an explicit preventive program which should start in primary school and continue through all grades. This would require additional school resources. The teachers deemed daily life more educational about sexuality than information from schools and universities. 52% said that AIDS education messages had to be clear about preventive sexual behavior. 32% believed that correct use of the condom had to be demonstrated in class. 78% identified the mass media for dissemination of AIDS information, and only 15% judged their knowledge about AIDS sufficient for imparting it to students.^ieng

RESUMO

The emergence of opportunities for support from the Global Fund to Fight AIDS, Tuberculosis and Malaria (GFATM) for HIV-related projects has so far generated funding of over US$75 million for three proposals in Peru. The size of this investment creates the need for close monitoring to ensure a reasonable impact. This paper describes the effects of collaboration with the GFATM on key actors involved in HIV-related activities and on decision-making processes; on health sector divisions; on policies and sources of financing; on equity of access; and on stigma and discrimination of vulnerable and affected populations. Data analysed included primary data collected through interviews with key informants, in-depth interviews and group discussions with vulnerable and affected populations, as well as several public documents. Multisectorality, encouraged by the GFATM, is incipient; centralist proposals with limited consultation, a lack of consensus and short preparation times prevail. No accountability mechanisms operate at the Country Coordinating Mechanism (CCM) level regarding CCM members or society as a whole. GFATM-funded activities have required significant input from the public sector, sometimes beyond the capacity of its human resources. A significant increase in HIV funding, in absolute amounts and in fractions of the total budget, has been observed from several sources including the National Treasury, and it is unclear whether this has implied reductions in the budget for other priorities. Patterns of social exclusion of people living with HIV/AIDS are diverse: children and women are more valued; while transgender persons and sex workers are often excluded.

RESUMO

PIP: An evaluation of AIDS prevention and sex education program during a 3-month period in 190 in Peruvian schools (7 controls and 7 with the program) found that the intervention, based on behavioral change models, influenced knowledge and attitudes. Knowledge of sexuality and AIDS was greater among study participants than among controls. Attitudes toward erotophobia, condoms, contraception, and people with AIDS were also different among participants. Intentions to adopt prevention-oriented behaviors were also greater among study participants. A follow-up of 250 students was conducted in order to assess actual behavior change; analysis is pending. The curriculum is easy to implement and low-cost. The intervention and evaluation were developed by researchers and planners at the Cayetano Heredia University in Lima. The curriculum emphasized empowerment, self-esteem, information, attitude change, skill development, and a supportive environment. The 14-hour program covered the following topics: 1) puberty and adolescence, 2) sexual anatomy and physiology and human sexual responses, 3) conception and pregnancy (delivery, breast feeding, and unwanted pregnancy), 4) planned parenthood and contraceptive technologies including abortion, 5) sex and gender (social and cultural aspects and sexual orientation), 6) AIDS/STDs and condom skills, and 7) personal decision making about sexual issues (assertive communication skills and self-determination). Two hours of instruction were provided for each of the 7 units. Support materials included teacher and student training manuals, charts, a sample contraceptive kit, and condoms. Teaching techniques ranged from role playing and brainstorming to collaborative study with friends, family, and community heath institutions. Teachers received special training prior to the intervention.^ieng
