Transgender HIV prevention: a qualitative needs assessment.

Although clinical experience and preliminary research suggest that some transgender people are at significant risk for HIV, this stigmatized group has so far been largely ignored in HIV prevention. As part of the development of HIV prevention education targeting the transgender population, focus groups of selected transgender individuals assessed their HIV risks and prevention needs. Data were gathered in the following four areas: (1) the impact of HIV/AIDS on transgender persons; (2) risk factors; (3) information and services needed; and (4) recruitment strategies. Findings indicated that HIV/AIDS compounds stigmatization related to transgender identity, interferes with sexual experimentation during the transgender 'coming out' process, and may interfere with obtaining sex reassignment. Identified transgender-specific risk factors include: sexual identity conflict, shame and isolation, secrecy, search for affirmation, compulsive sexual behaviour, prostitution, and sharing needles while injecting hormones. Community involvement, peer education and affirmation of transgender identity were stressed as integral components of a successful intervention. Education of health professionals about transgender identity and sexuality and support groups for transgender people with HIV/AIDS are urgently needed.

Perceptions of HIV/AIDS and caring for people with terminal AIDS in southern Thailand.

This study presents data collected from village-based ethnographic research conducted in southern Thailand in 1995-1996, and focuses on perceptions of HIV/AIDS infection, patients with AIDS and their provision of care. Individual interviews were conducted with 300 village women. These data were supplemented by data from 14 focus group discussions involving 100 participants, both men and women, randomly selected from six villages in Hatyai district, Songkla Province, Thailand. In addition, 23 people with HIV/AIDS and their caregivers participated in subsequent in-depth interviews. Participants generally obtained their information about HIV/AIDS from television and radio, and the information they obtained was generally negative. AIDS was perceived as a disease associated with dirt, danger and death, although it was also considered to be a disease of karma (rok khong khon mee kam) and a 'woman's disease' (rok phu ying) associated with prostitution. Few women perceived themselves to be at risk of infection because they 'trusted' their husbands to be faithful. There were some differences in attitudes towards caring for AIDS patients among people who lived in semi-urban and rural areas, and with areas which had not yet experienced AIDS among community members. Focus group discussions clarified issues related to the illness and patterns of caregiving among men and women. Areas of misperception and confusion were identified and will be used for interventions.

Knowledge, attitudes and practices concerning HIV/AIDS among sex workers in Phnom Penh, Cambodia.

The human immunodeficiency virus (HIV)/AIDS epidemic is currently spreading faster in Cambodia than anywhere else in Asia. Heterosexual transmission of HIV through prostitution is believed to be catalyzing the epidemic, and sex workers (SWs) are at a very high risk for becoming infected with HIV and subsequently developing AIDS. In order to gain a better understanding of the knowledge, attitudes and practices of this highly vulnerable population, face-to-face interviews were conducted with SWs (N = 502) in the capital city, Phnom Penh. The SWs surveyed were predominantly young, uneducated, poor women from rural areas, many of whom remain isolated in brothels. Brothel-based SWs are probably at greatest risk for acquiring HIV. They reported twice as many sexual contacts per day and used condoms less frequently than community-based SWs. The majority of SWs surveyed knew that condoms offered protection against HIV/AIDS, although one-quarter of SWs did not always use condoms. Despite their high level of baseline HIV/AIDS knowledge, nearly all SWs requested that additional health education materials be made available to them and their customers.

Heterosexual anal intercourse, health risks and drug use: a review with special attention to drug users.

Research studying HIV risk-taking behaviour has tended to focus on specific populations who are characterized by particular behaviours. Such practices include the extent of unprotected anal intercourse among homosexual men, the sharing of injecting equipment among drug users and unprotected vaginal intercourse among female sex workers. There is often a failure among both researchers and practitioners to address specific risk behaviours outside of the defined risk group. Reviewed here are studies of heterosexual anal intercourse, with special attention to drug users and female sex workers. Among the general population, the reporting of heterosexual anal intercourse varies greatly across time and cultural groups. However, a body of recent research suggests that, despite some geographical differences, rates in most countries are relatively high. Many studies have also found that associated condom usage is low. Although unprotected anal intercourse is known to be an efficient method for the transmission of HIV and other viral infections, it has rarely been addressed outside cohorts of men who have sex with men. Of particular concern is the interaction of risk behaviours among drug users and women engaging in prostitution, many studies having found high levels of unprotected anal intercourse among these groups. Harm reduction interventions must address all the health risk behaviours their target groups are engaging in, if the challenge of reducing the transmission of HIV and other viral infections is to be met.

The pattern of intravenous drug use and associated criminal activity in patients on a methadone treatment waiting list.

Sixty-four patients on the Christchurch Methadone Treatment Programme waiting list were questioned on their drug-use behaviour, criminal activity and sources of income, both legal and illegal, for the preceding 7 days. Opioids used included morphine sulphate tablets, methadone and opium poppies, while other drugs used included tranquillizers, cannabis and alcohol. A significant minority were prescribed opioids. The mean cost of drugs used in 7 days across all subjects was 882 dollars. The mean financial gain from criminal sources for the same period was 1079 dollars and was derived from drug-related crime, property crime and prostitution. Few gender differences were found relating to criminal activity or drug use. The majority of the sample were on unemployment benefits of varying types while a minority were in paid employment. Those in paid employment did not earn significantly less from criminal activity, nor did they spend significantly less on drug use than did those not in paid employment. An important implication of these findings is that untreated opioid users are a substantial financial burden to the community, strongly supporting the argument for greater treatment provision.

HIV/AIDS risk factors as portrayed in mass media targeting First Nations, Métis, and Inuit peoples of Canada.

PURPOSE: The purpose of this study was to describe the coverage and portrayal of human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) risk factors as framed in newspaper targeting Aboriginal (First Nations, Métis, and Inuit) peoples in canada. METHODS: From a sample of 31 Aboriginal newspapers published in English from 1996 to 2000, 14 newspapers were randomly selected. Of 167 articles published on HIV/AIDS during this time period, all anecdotal (n=34) and an approximate 25% random sample of scientific (n=32) articles were analyzed using both quantitative (coding reliability and frequencies) and qualitative (in-depth content analysis) analyses. RESULTS: Individual risk factors for HIV/AIDS were described in 74%, (49/66) of the articles and included unprotected sexual intercourse (20/49 or 41%), sharing of needles for injection drug use (IDU; 16/49 or 33%), infected blood transfusions (3/49 or 6%), and vertical transmission from mother to a baby (10/49 or 20%). Additional risk factors of alcohol use and poverty were mentioned in 29% and 25% of the articles. In addition to the well-recognized HIV/AIDS risk groups of prostitutes and homosexual men, sexual abuse victims, prisoners, and women were identified in aboriginal newspapers as being at risk. Although Aboriginal women were identified as being at high risk, the newspaper coverage also emphasized their lack of knowledge regarding HIV/AIDS. Heterosexual men were not mentioned as being at risk for HIV/AIDS in the newspaper articles. BACKGROUND: The prevalence of HIV/AIDS is higher among Canadian Aboriginals than in the general population. Local and community newspapers are an important channels for the dissemination of health information for isolated, rural, and aboriginal communities. INTERPRETATION: The findings show that Aboriginal media identify high-risk groups and individualistic risk factors for HIV/AIDS within a public health perspective.

Vulnerability on the streets: female sex workers and HIV risk.

In-depth interviews were conducted with 24 purposively selected female sex workers who were perceived to be vulnerable to risks associated with their lifestyle and occupation. Brothel workers were found to be considerably less exposed to risk than the women working on the streets. Client resistance was the major obstacle to women maintaining safe sex practices. Physical threats and coercion from clients, the absence of legal protection for street workers, the workers' extreme social isolation and lack of community support added to the difficulties experienced by women in their attempts to insist on condoms for all sex services. Youth, homelessness and heavy drug use had contributed to women being at times even more vulnerable because they had less capacity to manage situations of potential violence or STD risk. Whether through sex work or in their private relationships, HIV remains a risk for some of these women. This study highlights the dangers associated with illegal sex work. While decriminalization of prostitution would reduce some of the dangers to which women were exposed and increase women's capacity to insist on safe sex practices, it is also important for community education programmes to address men's failure to accept responsibility for condom use when seeking the services of sex workers.

Comparative profiles of women with PTSD and comorbid cocaine or alcohol dependence.

This study examined differences in substance abuse severity, trauma history, posttraumatic stress disorder (PTSD) symptomatology and psychiatric comorbidity among treatment-seeking women (N= 74) with PTSD and either comorbid cocaine or alcohol dependence. Women in the cocaine/PTSD group, compared with the alcohol/PTSD group, demonstrated greater occupational impairment (e.g., greater severity on the employment subscale of the Addiction Severity Index, less monthly income, fewer days worked in past month), more legal problems (e.g., greater number of months incarcerated and arrests for prostitution), and greater social impairment (e.g., fewer number of close friends, less likely to be married). Women in the alcohol/PTSD group evidenced higher rates of exposure to serious accidents, other situations involving serious injury, and other extraordinarily stressful life events. Rates of major depression and social phobia were higher among the alcohol/PTSD group than the cocaine/PTSD group. Women in the alcohol/PTSD group scored higher on the CAPS avoidance, hyperarousal, and total subscale scores. The current findings enhance our understanding of the substance-specific profiles of women with PTSD and comorbid substance use disorders and may have important implications for the design of dual-diagnosis interventions.

Use of clonidine for chemical submission.

CASE REPORT: An East-European prostitute in Amsterdam robbed several victims, after having sedated them with clonidine solution (available as plastic ampoules of eyedrops) added to her victims' drinks. One victim was hospitalized. His symptoms included bradycardia, hypotension, hypothermia, pallor, cyanosis, and impaired consciousness. Treatment included isoprenaline for 28 hours. The victim was released from hospital the next day. In court, the female offender confessed and was sentenced to prison for 3 1/2 years. She may have administered doses as high as 8 mg clonidine.

High dose cocaine use in São Paulo: a comparison of treatment and community samples.

This cross-sectional study investigates patterns of drug use and associated problems among 332 cocaine users from treatment and community samples in São Paulo, Brazil. Data were collected using a structured questionnaire and the Severity of Dependence Scale (SDS). The majority were regular users of high doses of smoked cocaine. After controlling for severity of cocaine use, users in the community were found to be more involved in illegal activities, more likely to report adverse effects of cocaine, to be involved in prostitution, and to have lived on the streets. Better methods are required to provide interventions to tackle the problems and risk behaviors of these cocaine users.

Use of psychoactive substances and sexual risk behavior in adolescents.

This study investigated the relationship between the use of illicit drugs and sexual-risk-behavior in a sample of students aged 14 to 21 years at a public high school in São Paulo in 1997. A total of 689 useable questionnaires documented the sample in consumption of psychoactive substances and sexual behavior. Sexual behavior of drug users and non-users was compared regarding history of complete sexual intercourse, age at first sexual intercourse, use of condoms, sexual intercourse with sex workers, and prostitution. Drug users (N = 366) presented a higher frequency of complete sexual intercourse (80.8% of users versus 53.5% of non-users), (N = 323, p < .001), a younger age at first sexual intercourse (on average 15.2 years in users versus 15.7 among non-users, p < .005), a trend toward lower use of condoms (56.7% among users versus 65.3% among non-users, p < .1), and more sexual intercourse with sex workers (31.1% among users versus 15% among non-users, p < .001). Sexual-risk-behavior increased with the number of drugs used. Alcohol and marijuana use were associated with the highest sexual-risk-behavior. These data are essential for the development of more specific preventive strategies, focusing on male alcohol and marijuana users.

Imprisoned drug offenders in Taiwan: a gender-based analysis.

Using data collected from a 1999 nationwide survey of 700 incarcerated drug users in Taiwan, this article compares gender differences with respect to childhood experiences, family characteristics, drug use patterns, and criminal histories. The results from both bivariate and logistic regression analyses document some gender differences and offer tentative support for feminist views. Overall, female drug offenders in Taiwan were more likely to have spouses with alcohol or drug use-associated problems, experience physical or sexual abuse, grow up in non-two-parent households, and hold temporary and stereotypical female jobs, including prostitution. Compared to men, although female drug offenders reported earlier involvement in criminal activities, they were less violent and had fewer prior arrests. As for sources, women relied on friends or acquaintances to procure their drugs. No gender differences were identified with respect to illicit drug type or duration and frequency of use.

Risk factors for human T cell lymphotropic virus type II infection among the Guaymi Indians of Panama.

To examine risk factors for human T cell lymphotropic virus type II (HTLV-II) infection, a case-control study was conducted among the Guaymi Indians of Panama. In females, HTLV-II seropositivity was associated with early sexual intercourse (</=13 vs. >15 years; odds ratio [OR], 2.50; 95% confidence interval [CI], 1.11-6.14) and number of lifetime sex partners. One partner increased risk of seropositivity by 30% (OR, 1.30; CI, 1.05-1.64), and risk increased with number of partners. Similar risk was associated with number of long-term sexual relationships. Among males, intercourse with prostitutes was associated with HTLV-II seropositivity (OR, 1.68; CI, 1.04-2.72). These data support a role for sexual transmission in HTLV-II infection. Association of seropositivity with primary residence in a traditional village (OR, 3.75; CI, 1.02-15.38) and lack of formal education (0 vs. >6 years [OR, 3.89; CI, 1.67-9.82]) observed in males may reflect differences in sexual practices associated with acculturation.

Resistance to human immunodeficiency virus type 1 in vitro as a surrogate of vaccine-induced protective immunity.

An in vitro assay developed as a correlate of vaccine-induced protection from human immunodeficiency virus (HIV) was validated in populations with relative resistance to HIV-1 as well as in HIV vaccine recipients. Cultures of peripheral blood mononuclear cells (PBMC) were challenged with 10 TCID50 of HIV-1MN or HIV-1BaL, titered in PBMC from normal controls (n=57). PBMC from HIV-1-infected persons with low viremia (n=17), exposed uninfected persons (n=23), and HIV-2-infected Senegalese prostitutes (n=9) were significantly resistant to HIV-1BaL and/or HIV-1MN (P<.001). Among 34 HIV vaccine recipients of live canarypox vector expressing multiple HIV-1 gene products with or without rgp120 booster, PBMC from postvaccination samples were significantly resistant to both strains (P<.001), and cytotoxic T lymphocyte precursor-positive samples were significantly more resistant than were precursor-negative samples (P<.03). This is the first evidence of the induction by vaccination of a validated correlate of protection. This assay should serve as a useful criterion for assessing experimental HIV vaccines before phase III efficacy trials.

Virus load during primary Human Immunodeficiency Virus (HIV) type 1 infection is related to the severity of acute HIV illness in Kenyan women.

We evaluated the association between the severity of primary human immunodeficiency virus type 1 (HIV-1) illness and HIV-1 plasma virus load before seroconversion using stored plasma samples obtained from 74 prostitutes in Mombasa, Kenya. Fever, vomiting, headache, fatigue, arthralgia, myalgia, sore throat, skin rash, or being too sick to work were each associated with significantly higher virus loads before HIV-1 seroconversion, and each additional symptom or sign was associated with an increase in virus load of 0.4 log(10) copies/mL.

Shedding of human herpesvirus 8 in oral and genital secretions from HIV-1-seropositive and -seronegative Kenyan women.

Polymerase chain reaction was used to determine the prevalence and correlates of human herpesvirus 8 (HHV8) in saliva, mouth, cervical, vaginal, plasma, and peripheral-blood mononuclear cell (PBMC) samples from 174 HHV8-seropositive female prostitutes in Mombasa, Kenya. The prevalence of detection of HHV8 was 32% in saliva samples, 28% in mouth swabs, 4% in cervical swabs, 2.3% in vaginal swabs, 9% in plasma samples, and 18% in PBMC samples. Human immunodeficiency virus type 1 (HIV-1) seropositivity was associated with detection of HHV8 from any mucosal surface (odds ratio, 2.1 [95% confidence interval, 1.1-4.0]). In HIV-1-seropositive women, there was no association between detection of HHV8 and either CD4 count or HIV-1 viral load.

Female-to-male infectivity of HIV-1 among circumcised and uncircumcised Kenyan men.

BACKGROUND: A lack of male circumcision has been associated with increased risk of human immunodeficiency virus type 1 (HIV-1) acquisition in a number of studies, but questions remain as to whether confounding by behavioral practices explains these results. The objective of the present study was to model per-sex act probabilities of female-to-male HIV-1 transmission (i.e., infectivity) for circumcised and uncircumcised men, by use of detailed accounts of sexual behavior in a population with multiple partnerships. METHODS: Data were collected as part of a prospective cohort study of HIV-1 acquisition among 745 Kenyan truck drivers. Sexual behavior with wives, casual partners, and prostitutes was recorded at quarterly follow-up visits. Published HIV-1 seroprevalence estimates among Kenyan women were used to model HIV-1 per-sex act transmission probabilities. RESULTS: The overall probability of HIV-1 acquisition per sex act was 0.0063 (95% confidence interval, 0.0035-0.0091). Female-to-male infectivity was significantly higher for uncircumcised men than for circumcised men (0.0128 vs. 0.0051; P=.04). The effect of circumcision was robust in subgroup analyses and across a wide range of HIV-1 prevalence estimates for sex partners. CONCLUSIONS: After accounting for sexual behavior, we found that uncircumcised men were at a >2-fold increased risk of acquiring HIV-1 per sex act, compared with circumcised men. Moreover, female-to-male infectivity of HIV-1 in the context of multiple partnerships may be considerably higher than that estimated from studies of HIV-1-serodiscordant couples. These results may explain the rapid spread of the HIV-1 epidemic in settings, found throughout much of Africa, in which multiple partnerships and a lack of male circumcision are common.

Genital ulcers: etiology, clinical diagnosis, and associated human immunodeficiency virus infection in Kingston, Jamaica.

Individuals presenting consecutively with genital ulcers in Kingston, Jamaica, underwent serological testing for human immunodeficiency virus (HIV) infection, chlamydial infection, and syphilis. Ulcer material was analyzed by multiplex polymerase chain reaction (M-PCR) analysis. DNA from herpes simplex virus (HSV), Haemophilus ducreyi, and Treponema pallidum was detected in 158 (52.0%), 72 (23.7%), and 31 (10.2%) of 304 ulcer specimens. Of the 304 subjects, 67 (22%) were HIV-seropositive and 64 (21%) were T. pallidum-seroreactive. Granuloma inguinale was clinically diagnosed in nine (13.4%) of 67 ulcers negative by M-PCR analysis and in 12 (5.1%) of 237 ulcers positive by M-PCR analysis (P = .03). Lymphogranuloma venereum was clinically diagnosed in eight patients. Compared with M-PCR analysis, the sensitivity and specificity of a clinical diagnosis of syphilis, herpes, and chancroid were 67.7%, 53.8%, and 75% and 91.2%, 83.6%, and 75.4%, respectively. Reactive syphilis serology was 74% sensitive and 85% specific compared with M-PCR analysis. Reported contact with a prostitute in the preceding 3 months was associated with chancroid (P = .009), reactive syphilis serology (P = .011), and HIV infection (P = .007). The relatively poor accuracy of clinical and locally available laboratory diagnoses pleads for syndromic management of genital ulcers in Jamaica. Prevention efforts should be intensified.
