Sex workers have long been considered a high-risk group for HIV infection, but to date little quantitative research has explored the association between HIV risk and exchange of sex for material gain by women in the general population. The objective of this study was to estimate the prevalence of such transactional sex among women attending antenatal clinics in Soweto, South Africa, to identify demographic and social variables associated with reporting transactional sex, and to determine the association between transactional sex and HIV serostatus. We conducted a cross-sectional study of women seeking antenatal care in four Soweto health centres who accepted routine antenatal HIV testing. Private face-to-face interviews covered socio-demographics, sexual history and experience of gender-based violence. 21.1% of participants reported having ever had sex with a non-primary male partner in exchange for material goods or money. Women who reported past experience of violence by male intimate partners, problematic substance use, urban residence, ever earning money, or living in substandard housing were more likely to report transactional sex, while women who reported delayed first coitus, were married, or had a post-secondary education were less likely to report transactional sex. Transactional sex was associated with HIV seropositivity after controlling for lifetime number of male sex partners and length of time a woman had been sexually active (OR = 1.54, 95% CI: 1.07, 2.21). Women who reported non-primary partners without transactional sex did not have increased odds of being HIV seropositive (OR = 1.04, 95% CI: 0.75, 1.43). We conclude that transactional sex may place women at increased risk for HIV, and is associated with gender-based violence, substance use and socio-economic disadvantage. Research, policy and programmatic initiatives should consider the role of transactional sex in women's HIV risk, with attention to the intersecting roles of violence, poverty, and substance use in shaping women's sexual behaviour.  相似文献

Sexual power and HIV risk, South Africa   总被引:1,自引:0,他引:1  
Gender power inequities are believed to play a key role in the HIV epidemic through their effects on women's power in sexual relationships. We hypothesized that lack of sexual power, measured with a four-point relationship control scale and by a woman's experience of forced sex with her most recent partner, would decrease the likelihood of consistent condom use and increase the risk for HIV infection among sexually experienced, 15- to 24-year-old women in South Africa. While limited sexual power was not directly associated with HIV, it was associated with inconsistent condom use: women with low relationship control were 2.10 times more likely to use condoms inconsistently (95% confidence interval [CI] 1.17-3.78), and women experiencing forced sex were 5.77 times more likely to use condoms inconsistently (95% CI 1.86-17.91). Inconsistent condom use was, in turn, significantly associated with HIV infection (adjusted odds ratio 1.58, 95% CI 1.10-2.27).  相似文献

OBJECTIVE: To identify risk factors associated with positive HIV serostatus among African American women who smoke crack and/or inject drugs and who are not enrolled in drug treatment or another institutional setting. METHODS: Baseline interviews were conducted from June 1998 to June 2000 with 379 heterosexually active women (ages 18 to 59) who had been recruited for potential enrollment into an HIV intervention trial. RESULTS: Adjusted for age and drug using status, women who expressed more difficulty saying no to sex with male partners were more likely to be HIV-positive (adjusted odds ratio [aOR]=3.08, 95% confidence interval [CI] 2.02, 4.83). Similarly, those who indicated greater communication with casual sex partner(s) were less likely to test positive (aOR=0.29, 95% CI 0.10, 0.89). Lower HIV internal control and a history of cuts or burns on lips due to crack smoking were also associated with positive serostatus, and were important confounders in the final multivariate model. A higher level of internal control was associated with a decreased likelihood of positive serostatus, while a history of cuts or burns on the lips was associated with an increased likelihood of HIV antibodies, even after controlling for the amount of oral sex. CONCLUSIONS: A broad array of factors may promote or avert infection with HIV. The degree to which personal attributes and beliefs, and relationship characteristics contribute to the likelihood of infection must continue to be addressed. The importance of oral sex and presence of oral sores and their potential role in transmission was suggested.  相似文献

ABSTRACT

Background: Young women in South Africa are at high risk for HIV, particularly after they leave school. There are few studies examining the long-term impact of school-based public health interventions aimed at protecting young women from HIV. We undertook a long-term evaluation of an extracurricular, school-based HIV prevention program, that leveraged off a mass media television series in South Africa.

Methods: We recruited 403 women aged 18–28 years. One hundred and seventy were members of Soul Buddyz Clubs (SBCs) between 2004 and 2008 and 233 were matched controls from the same communities as the ex-Buddyz. Face-to-face interviews were conducted and HIV testing undertaken. Analysis was restricted to 320 women who had ever had sex (136 ex-Buddyz and 184 controls). Multivariate analysis in Stata v14 was conducted.

Findings: 16.4% of women tested HIV positive. Ex-Buddyz were more likely to be HIV negative than controls (AOR 2.92, 95% CI 1.26–6.77, p = 0.013). Ex-Buddyz were more likely to have only had one sexual partner in the past year (AOR 2.14, 95% CI 1.17–3.89, p = 0.013) and 1.7 times more likely to have used a condom at first sex (95% CI 0.99–2.92, p = 0.053).

Interpretation: Participation in an SBC is associated with a decrease in young women’s HIV risk and suggests an impact on some key risky sexual behaviors. School-based prevention programs that leverage off of other media platforms demonstrate a positive outcome on health status.  相似文献

Alcohol use is a known key risk factor associated with risky sexual behavior that contributes to HIV transmission. This cross-sectional study used time location sampling to investigate alcohol use and risky sexual behaviors that occurred after ingesting alcohol among 609 patrons of alcohol venues in Gaborone, Botswana. Alcohol Use Disorders Identification Test (AUDIT) scores were categorized as low (1–7), medium (8–15), and high (16+) for analysis. Logistic regression models stratified by gender assessed the association between alcohol use and condom use at last sex after drinking alcohol. Among females, the odds of condom use during last sex after drinking alcohol were significantly lower for high compared to low AUDIT scores (AOR?=?0.17, 95 % CI 0.06–0.54). Among males, factors significantly associated with condom use at last sex after alcohol use were low levels of education (primary level compared to university and above AOR?=?0.13; 95 % CI 0.03–0.55) and beliefs that alcohol use did not increase risky sexual behaviors (AOR?=?0.26; 95 % CI 0.11–0.62). HIV prevention interventions should target females and emphasize sexual risks associated with alcohol use.  相似文献

Deported injection drug users (IDUs) in Mexico may be vulnerable to HIV infection following expulsion from the USA. We examined factors associated with HIV risk perception among a sample of deportees in Tijuana. From January to April 2010, 313 male IDUs who reported ever being deported from the USA completed a questionnaire. Overall, 35% (N = 110) of deportees perceived HIV risk. In multivariate logistic regression analyses, factors independently associated with HIV risk perception included ever having a steady female partner in Tijuana post-deportation (adjusted odds ratio [AOR]: 2.26; 95% confidence interval [CI]: 1.01–5.07) and years spent in a US prison (AOR: 1.29 per year; 95% CI: 1.13–1.48). Conversely, years of drug injection use (AOR: 0.95 per year; 95% CI: 0.91–0.99), ever witnessing family members use drugs prior to first migration trip (AOR: 0.24; 95% CI: 0.09–0.65), years of residence in the USA (AOR: 0.91 per year; 95% CI: 0.84–0.98) and being a Tijuana native (AOR: 0.40; 95% CI: 0.16–0.99) were negatively associated with HIV risk perception. US–Mexico border cities that receive deported migrants should target HIV prevention interventions to specific subgroups, including drug-using male deportees. Interventions should consider migrant's time in the USA, the role of their social networks, and reducing missed opportunities for HIV testing/education.  相似文献

Interactions between HIV and surgical diseases are relatively poorly described in high HIV prevalence settings. We report HIV prevalence and its associations in a prospective study of adults admitted to surgical units in Soweto, South Africa. Voluntary counselling and testing (VCT) for HIV was offered to surgical inpatients. Research nurses interviewed participants at enrolment and doctors reviewed records after discharge. In HIV-infected participants, CD4 counts and viral loads were ascertained. Of 1000 participants, 537 consented to VCT, of whom 176 (32.8%, 95% CI 28.8-36.9%) tested HIV positive. A history of tuberculosis (adjusted odds ratio (AOR) 3.0, 95% CI 1.5-6.2) or sexually transmitted infection (AOR 2.7, 95% CI 1.8-4.2) was associated with HIV infection. Diagnoses of cutaneous abscesses (OR 3.4, 95% CI 1.4-8.1) and anorectal sepsis (OR 3.1, 95% CI 1.1-9.0) were associated with HIV and indicated advanced disease. There were no differences in rates of operative procedures, wound sepsis, investigations or length of stay by HIV status. Hospital-acquired pneumonia was more common in HIV-infected participants (P=0.028). In conclusion, in this high HIV prevalence setting, resource utilisation is similar between HIV-infected and uninfected patients in surgical wards where high rates of HIV in young adults support routine HIV testing. WHO clinical staging of HIV should include anal sepsis as an indicator of advanced HIV disease.  相似文献

Limited research has examined the social context surrounding stigma and discrimination and HIV outcomes among people living with HIV (PLHIV). We surveyed 900 PLHIV in Brazil and examined the relationship between stigma, discrimination and HIV outcomes utilising multivariable logistic regression. HIV stigma and discrimination were inversely associated with age (AOR Stigma 0.65, 95% CI 0.49–0.88; AOR Discrimination 0.72, 95% CI 0.54–0.95) and income (AOR Stigma 0.74, 95% CI 0.55–0.99; AOR Discrimination 0.62, 95% CI 0.46–0.82). Stigma was inversely associated with education (AOR 0.71, 95% CI 0.52–0.96) and no history of sex work (AOR 0.56, 95% CI 0.35–0.90), and positively associated with having children (AOR 1.71, 95% CI 1.18–2.48). Discrimination was inversely associated with no history of drug use (AOR 0.63, 95% CI 0.42–0.95). Stigma and discrimination were found to be inversely associated with overall health (AOR Stigma 0.54, 95% CI 0.40–0.74; AOR Discrimination 0.71, 95% CI 0.52–0.97). Discrimination was associated with having a sexually transmitted infection since HIV diagnosis (AOR 1.63, 95% CI 1.14–2.32). Findings suggest that future interventions should address multiple social inequalities faced by PLHIV to reduce HIV stigma and discrimination and improve health and HIV outcomes.  相似文献

OBJECTIVE: To describe factors associated with HIV infection in men aged 15-26 years. SETTING: Rural Eastern Cape Province, South Africa. SAMPLE: A total of 1277 sexually experienced Xhosa male volunteers from 70 villages participating in a cluster randomized controlled trial of an HIV behavioural intervention. Xhosas circumcise during manhood initiation rituals. DESIGN: Cross-sectional, analysis of the study's baseline interviews. MAIN MEASURE: HIV sero-status, sexual practices measured with an interviewer-administered questionnaire. RESULTS: About 2% of the men were HIV positive. A logistic regression model showed HIV positivity to be associated with age (OR 1.55; 95%CI 1.22-1.95), having made a woman pregnant (OR 2.93; 95% CI 1.28-6.68), having been circumcised (OR 0.40; 95% CI 0.16-0.98), and having had sex with a man (OR 3.61; 95% CI 1.0-13.0). CONCLUSIONS: Our findings provide further evidence to suggest that circumcision is protective. There was much heterosexual risk taking among men but only pregnancy (with its association with sexual frequency) predicted HIV sero-positivity. Although relatively rare, same-sex sexual experiences were a risk factor. Male-male sexual contact is rarely assessed in HIV research in Africa and almost never addressed in general HIV prevention programming. Our findings suggest that it should be given more attention.  相似文献

Female sex workers are particularly susceptible to HIV-infection in Russia. However, a dearth of information exists on their utilisation of HIV services. A mixed-methods, cross-sectional study was conducted to examine motivators and barriers to HIV testing among street-based sex workers in St. Petersburg, Russia. The health belief model was the theoretical framework for the study. Twenty-nine sex workers participated in in-depth interviews, and 139 sex workers completed interviewer-administered surveys between February and September 2009. Barriers to getting an HIV test were fear of learning the results, worrying that other people would think they were sick, and the distance needed to travel to obtain services. Motivators for getting tested were protecting others from infection, wanting to know one's status and getting treatment if diagnosed. Logistic regression analysis demonstrated that knowing people living with HIV [aOR?=?6.75, 95% CI (1.11, 41.10)] and length of time since start of injection drug use [aOR?=?0.30, 95% CI (0.09, 0.97)] were significantly associated with recently getting tested. These results are important to consider when developing public health interventions to help female sex workers in Russia learn their HIV status and get linked to care and treatment services if needed.  相似文献

Migration processes are listed within the primary factors facilitating the heterosexual spread of HIV. The study examines the relationship between social support, sexual HIV risk behaviors and sexually transmitted infections (STIs) among 1342 male migrant and non-migrant market workers from Barakholka Market in Almaty, Kazakhstan. Results: (1) higher level of perceived social support [Enhancing Recovery in Coronary Heart Disease (ENRICHD) Social Support Instrument (ESSI score)] was associated with a lower likelihood of having sex with a female sex worker (FSW) [OR?=?0.952 (0.927, 0.978) p?<?.001]; (2) higher availability of friends was associated with a higher likelihood of having STIs [OR?=?1.244 (1.007, 1.537), p?<?.05]; (3) larger network size was associated with a higher likelihood of having STIs [OR?=?1.201 (1.026, 1.407), p?<?.05]; (4) loneliness was associated with an increased likelihood of having unprotected sex with any female partner [RR?=?1.102 (1.027, 1.182), p?<?.05]. Results suggest that social support factors should be considered as a component of HIV and STI prevention programs for male migrant workers from Central Asia in Kazakhstan.  相似文献

We evaluated the association between social support received from significant others, family, and friends and HIV-related sexual risk behaviors among African American men involved in the criminal justice system. Project DISRUPT is a cohort study among African American men released from prison in North Carolina (N?=?189). During the baseline (in-prison) survey, we assessed the amount of support men perceived they had received from significant others, family, and friends. We measured associations between low support from each source (<median value) and participants’ sex risk in the 6 months before incarceration. Low levels of social support from significant others, family, or friends were associated with poverty and homelessness, mental disorders, and substance use. Adjusting for age, poverty, and other sources of support, perceiving low support from significant others was strongly associated with multiple partnerships (fully adjusted odds ratio (OR) 2.64, 95% confidence interval (CI) 1.29–5.42). Low significant other support also was strongly associated with sex trade involvement when adjusting for age and poverty status (adjusted OR 3.51, 95% CI 1.25–9.85) but further adjustment for low family and friend support weakened the association (fully adjusted OR 2.81, 95% CI 0.92–8.55). Significant other support was not associated with other sex risk outcomes including concurrent partnerships, anal sex, or sex with an STI/HIV-infected partner. Low family support was associated with multiple partnerships in analyses adjusting for age and poverty (adjusted OR 1.98, 95% CI 1.05–3.76) but the association weakened and was no longer significant after adjusting for other sources of support (fully adjusted OR 1.40, 95% CI 0.65–3.00); family support was not correlated with other risk behaviors. Friend support was not significantly associated with sex risk outcomes. Indicators of overall support from any source were not associated with sex risk outcomes. Helping inmates maintain ties may improve economic security and well-being during community re-entry, while supporting and strengthening relationships with a significant other in particular may help reduce sex risk. Studies should evaluate the protective effects of distinct support sources to avoid masking effects of support and to best understand the influence of social support on health.  相似文献

Neighborhood social and physical factors shape sexual network characteristics in HIV-seronegative adults in the U.S. This multilevel analysis evaluated whether these relationships also exist in a predominantly HIV-seropositive cohort of women. This cross-sectional multilevel analysis included data from 734 women enrolled in the Women’s Interagency HIV Study’s sites in the U.S. South. Census tract-level contextual data captured socioeconomic disadvantage (e.g., tract poverty), number of alcohol outlets, and number of non-profits in the census tracts where women lived; participant-level data, including perceived neighborhood cohesion, were gathered via survey. We used hierarchical generalized linear models to evaluate relationships between tract characteristics and two outcomes: perceived main sex partner risk level (e.g., partner substance use) and perceived main sex partner non-monogamy. We tested whether these relationships varied by women’s HIV status. Greater tract-level socioeconomic disadvantage was associated with greater sex partner risk (OR 1.29, 95% CI 1.06–1.58) among HIV-seropositive women and less partner non-monogamy among HIV-seronegative women (OR 0.69, 95% CI 0.51–0.92). Perceived neighborhood trust and cohesion was associated with lower partner risk (OR 0.83, 95% CI 0.69–1.00) for HIV-seropositive and HIV-seronegative women. The tract-level number of alcohol outlets and non-profits were not associated with partner risk characteristics. Neighborhood characteristics are associated with perceived sex partner risk and non-monogamy among women in the South; these relationships vary by HIV status. Future studies should examine causal relationships and explore the pathways through which neighborhoods influence partner selection and risk characteristics.  相似文献

The objective of the present study was to determine the factors independently associated with disclosure of seropositivity to one’s steady sexual partner in people living with HIV (PLHIV) who are recipients of services provided by Association de Lutte Contre le Sida, a Moroccan community-based organization (CBO) working on AIDS response. Between May and October 2011, 300 PLHIV were interviewed about their sociodemographic and economic characteristics, their sexual life and disclosure of their serostatus to their friends, family and to their steady sexual partner. A weighted logistic regression was used to study factors associated with serostatus disclosure to one’s steady sexual partner. We restricted the analysis to people who declared they had a steady sexual partner (n = 124). Median age was 36 years old, 56 % were men and 62 % declared that they had disclosed their serostatus to their steady sexual partner. The following factors were independently associated with disclosure: living with one’s steady sexual partner [OR 95 % CI: 9.85 (2.86–33.98)], having a higher living-standard index [2.06 (1.14–3.72)], regularly discussing HIV with friends [6.54 (1.07–39.77)] and CBO members [4.44 (1.27–15.53)], and having a higher social exclusion score [1.24 (1.07–1.44)]. Unemployment (as opposed to being a housewife) was negatively associated with disclosure [0.12 (0.02–0.87)]. Despite the potential positive effects for the prevention of HIV transmission and for adherence to HIV treatment, many PLHIV had not disclosed their serostatus to their steady sexual partner. Some factors shown here to be significantly associated with such disclosure will help in the development of future support interventions.  相似文献

Objectives

Male sex workers (MSW) in Vietnam face high levels of stigma related to sex work, which may be associated with depression and increased vulnerability to HIV.

Methods

In 2010, 300 MSW completed a behavioral and psychosocial survey. Multivariable models assessed factors associated with sex work-related stigma and the association between stigma and depression.

Results

Factors associated with increased stigma included having disclosed sexual orientation to healthcare workers (b 1.75, 95 % CI 0.69–2.80), meeting clients in the street/park (b 1.42, 95 % CI 0.32–2.52), and having been forced to have sex without a condom (b 2.36, 95 % CI 1.27–3.45). Factors associated with decreased stigma included meeting clients via the telephone or internet (b ?1.26, 95 % CI ?2.39 to ?0.12) and receiving financial support from family or friends (b ?1.31, 95 % CI ?2.46 to ?0.17). Stigma was significantly associated with increased odds of depression (AOR 1.07, 95 % CI 1.01–1.15).

Conclusions

Addressing stigma and depression in HIV prevention interventions is crucial for tailoring these programs to MSWs’ needs, and may result in decreased HIV spread.  相似文献
