During mid-1987 to mid-1988 and mid-1990 to mid-1991, researchers conducted cross sectional serological surveys at the STD clinic in Port of Spain in Trinidad to examine trends in HIV-1 prevalence among 2019 and 1606 STD patients, respectively. They also conducted a case control study of risk factors for HIV-1 infection among heterosexual STD patients (131 cases and 173 age- and sex-matched controls) in 1992-1993. Between 1987-1988 and 1990-1991, HIV-1 seroprevalence increased markedly (3% to 13.6%). It increased more in women than in men (9- vs. 4-fold). During 1987-1988, men were more likely to be infected with HIV-1 (odds ratio [OR] = 3.1), but by 1990-1991, gender was no longer a significant risk factor (OR = 1.3). In 1990-1991, significant risk factors for HIV-1 infection were urban residence (OR = 2.2), HTLV-1 infection (OR = 3.1), and being at least 40 years old (OR = 1.8). None of these risk factors were significant in 1987-1988. HIV-1/HTLV-1 coinfection increased between the two surveys (0.05% to 1.5%). Significant independent HIV-1 risk factors in men identified in the case control study were: used crack cocaine in the past 6 months (adjusted OR [AOR] = 6.2; p = 0.0001); ever had anal sex (AOR = 7.2; p = 0.003); ever had syphilis (AOR = 3.2; p = 0.02); current genital ulcer disease (AOR = 5.2; p = 0.0001); and current genital warts (AOR = 3.9; p = 0.02). Significant independent HIV-1 risk factors in women were: less than 14 years old at first sex (OR = 4.8; p = 0.01); ever been a commercial sex worker (AOR = 5.7; p = 0.02); and ever had nongonococcal cervicitis (AOR = 4.1; p = 0.005). These findings suggest that sexual exposure to HIV-1 through ulcers for men and inflammatory STD and/or prostitution for women, all fueled by the crack cocaine epidemic, account for much of HIV-1 exploding in Trinidad. Public health interventions to prevent, detect, and treat STDs and crack cocaine addition may greatly reduce HIV-1 transmission.

A survey was carried out in 2 drug use treatment centres (TCs) in Rio de Janeiro, Brazil, to assess risk behaviours, HIV infection and other sexually transmitted infections/blood-borne infections (STIs/BBIs). Two hundred and twenty-five drug users (195 males and 30 females) were interviewed and clinically examined, and their blood and urine were tested for STIs/BBIs. Prevalences (%) for these infections were as follows--HIV: 0.9, hepatitis B virus (HBV): 14.7, hepatitis C virus (HCV): 5.8, syphilis: 5.3, gonorrhoea/chlamydia (CT/NG): 4.7. In bivariate analyses CT/NG infection was associated with younger age (P=0.003); current genitourinary symptoms (odds ratio [OR]=6.2) and a mainly illegal source of income (OR=9.1). Hepatitis C infection was associated with a history of ever having injected any drug (OR=19.6), and with each one of the injected drugs. After multiple logistic regression, lower educational level (adjusted odds ratio [AOR]=3.70) and 'ever having injected drugs' (AOR=3.69) remained as independent risk factors for hepatitis B infection. In conclusion, TCs must implement programmes directed towards the prevention of STIs/BBIs.

This study of 921 adolescents found condom failure (past 90 days) was experienced by at least one-third of the sample, regardless of gender. Frequency of condom failure was positively associated with STD diagnosis (AOR = 1.22, 95% CI = 1.01-1.48), with the odds of testing positive increasing 22% for each added event of failure.

Most patients attending urban STD clinics can benefit from workshops designed to promote sexual health and reduce sexual risk behaviors. However, many patients do not attend such workshops when invited. The purpose of this study was to evaluate the effects of providing a financial incentive on attendance at a sexual risk reduction workshop tailored to patients at an urban STD clinic. A quasi-experimental design with two conditions (incentive vs no incentive) was implemented sequentially with 107 STD clinic patients (58 men, 49 women; 69% African American; mean age = 27 years) reporting risky sexual behavior. Attendance at a subsequent sexual risk reduction workshop served as the key outcome. Results indicated that participants who were provided with a $30 cash incentive were more likely to attend the risk reduction workshop (38%) than participants who were not offered an incentive (9%), chi (1, N = 107) = 12.88, p < .001. Additional analyses confirmed that incentive (AOR = 7.59, p < .001) predicted attendance even after controlling for other significant predictors, namely, employment status (AOR = 3.04, p < .05) and age (AOR = 1.07, p < .05). We conclude that financial incentives are an effective way to increase attendance at sexual risk reduction workshops for at-risk urban populations.

The question of whether people will engage in greater levels of HIV-associated risk behaviour after receiving an AIDS vaccine has not been sufficiently investigated. Three objectives were: (1) assess the likelihood that people will engage in greater levels of HIV-risk behaviour after receiving an AIDS vaccine; (2) determine the association of increases with vaccination intent; and (3) identify differences between people who would and would not increase their HIV-risk behaviour after vaccination.A cross-sectional survey was conducted of 278 adults from three populations: gay men, African-American women, and persons who used illicit drugs. Nearly one-quarter of the sample indicated a likelihood that their HIV-risk behaviour would increase after vaccination. This increase was positively associated (r = 0.24) with increased intent to be vaccinated. Previous worry about having HIV (adjusted odds ratio [AOR] = 3.4, P = 0.004), being 32 years of age or older (AOR = 2.9, P = 0.0007), and having less than a high school education (AOR = 2.3, P = 0.027) were each associated with a post-vaccination increase in HIV risk. With the seemingly real potential for increased HIV-risk behaviours after being vaccinated against AIDS, intervention studies are warranted to identify strategies with potential to minimize this phenomenon.

We studied predictors of no prenatal care (PNC) and influence of no PNC on pregnancy outcome in a multisite study of 1071 women with syphilis in Russia. We assessed PNC utilization, HIV testing, syphilis treatment, and pregnancy outcome. We found that 37% of women with syphilis received no PNC, and 1% was HIV infected. Lacking official residency status was independently related to no PNC (adjusted odds ratio [AOR]: 8.1; 95% confidence intervals [CI]: 5.3-12.3). Among women with inadequately treated current syphilis, those without PNC were more likely to have a stillborn infant than those with PNC (25% vs. 3%, odds ratio [OR] 9.5, 95% CI 4.0-23.5). Women with adequately treated current syphilis and no PNC were more likely to deliver a low birth weight (OR 3.8; 95% CI 1.8-8.1) or preterm infant (OR 3.9; 95%CI 1.8-8.7). Women with previous or current syphilis and no PNC were significantly more likely to abandon their infants.

Understanding predisposing factors for sexually transmitted infections (STIs) in young adults may identify targets for public health interventions. We conducted a cross-sectional web-based survey of university students' sexual attitudes, behaviours and lifestyles and self-reported rates of STI. A total of 827 students responded, 22.4% had two or more sexual partners in the previous year with inconsistent condom use and the lifetime prevalence of STIs was 9.6%. Factors associated with a diagnosis of STI were increasing age and number of sexual partners ever, female gender (adjusted odds ratio [AOR] 2.70, 95% confidence interval [CI] 1.31, 5.56) and use of crack (AOR 10.45, 95% CI 1.46, 75.16). For female students, these were increasing age and number of partners ever, whereas for male students having sex with other men (bisexual AOR 4.8, 95% CI 1.02, 22.595, homosexual AOR 17.66, 95% CI 3.03, 103.04) and use of crack (AOR 32.24, 95% CI 3.33, 312.08). Multiple partners and recreational drug use may predict incidence of STI. Prevention strategies need to aim at reducing risk behaviour across various activities.

The purpose of this study was to assess the prevalence and risk factors for syphilis infection among female sex workers (FSWs) in Liuzhou City, Guangxi Zhuang Autonomous Region, southern China. A cross-sectional study recruited FSWs using a venue-based method and subsequent snowball sampling with mapping strategies. Questionnaire-based interviews were conducted to collect demographic and behavioral information. Blood was tested for syphilis (RPR with TPPA confirmation) and HIV (EIA with Western blot confirmation) infections. Of the 362 eligible participants, 81.7% were non-local residents (60.5% from other parts of Guangxi and 21.2% were non-Guangxi residents); 58.0% belonged to non-Han minority ethnic groups; 37.5% reported inconsistent condom use with their clients and 71.2% reported inconsistent condom use with their regular sex partners during the past month. Nearly 10% reported having had sex with drug users. The prevalence rates for HIV and syphilis infections were 2.3% and 11.0%, respectively. Almost half (46.6%) of participants reported having had STD symptoms. Inconsistent condom use with clients in the past month (AOR = 5.0; 95% CI = 1.8-13.8), less education (OR = 2.6; 95% CI = 1.1-7.4), and HIV infection (AOR = 8.1; 95% CI = 1.1-68.5) were independently associated with syphilis infection.

The expense in time and money limit the use of randomized clinical trials (RCT) and cohort studies for evaluating long-term AIDS treatment outcomes. We conducted a case-control study to characterize predictors of AIDS mortality after the availability of highly active antiretroviral therapy (HAART) in San Francisco, in which cases were matched with controls on stage of disease, year of AIDS diagnosis and year of HAART initiation. Overall, 266 cases and 1173 controls were included, representing >90% of eligible patients. The class of initial HAART regimen was not associated with mortality. Predictors of mortality were older age ([adjusted odds ratio] AOR 1.23, 95% [confidence interval] CI: 1.13-1.35), public versus private health insurance (AOR 2.80, 95% CI: 1.77-4.42), no versus private insurance (AOR 1.45, 95% CI: 1.02-2.07) and unboosted saquinavir (AOR 2.50, 95% CI: 1.34-4.65). Survival benefit was found in following the 2004 US Department of Health and Human Services preferred treatment guidelines; borderline survival benefits were found in following the guidelines from other years. Similar predictors were found for all-cause and AIDS-specific mortality. Our findings mirrored those of RCT and multi-centre cohort studies, and may be applicable to other settings. Our findings support similar survival benefit to persons initiating HAART with non-nucleoside reverse transcriptase inhibitor- or protease inhibitor-based regimens.

Psychiatric co-morbidity and sex trade were tested as correlates of sexually transmitted infections (STIs) among 76 pregnant heroin- or cocaine-dependent women. Participants were recruited from a drug treatment programme and attended a clinician-administered assessment including the Structured Clinical Interview for DSM-IV (SCID-IV-TR) and self-report questionnaires about lifetime histories of sex trade and STIs (i.e. gonorrhoea, syphilis, chlamydia, herpes, genital warts or trichomonas). Lifetime and six month rates of STIs were 53.9% and 18.4%, respectively. The majority of women also had lifetime histories of psychiatric co-morbidity (61.8%) and/or sex trade (60.5%). Participants with psychiatric co-morbidity (adjusted odds ratio [AOR] 3.9; 95% confidence interval [CI] 1.3-11.6) and/or sex trade (AOR 3.2; 95% CI 1.1-9.5) were more likely to report STIs during their lifetime compared with those without such histories while controlling for age, education and race/ethnicity. Results suggest that as many as one-in-five pregnant heroin- or cocaine-dependent women in treatment have one or more STIs that are concurrent with their pregnancy and may contribute to risk for contracting HIV and pregnancy complications; psychiatric co-morbidity and/or sex trade were associated with greater STI risk. Findings underscore the importance of identifying and addressing co-morbid psychiatric disorders and sex trade behaviour in this population.
