We assessed the relationship between stress, substance use and sexual risk behaviors in a primary care population in Cape Town, South Africa. A random sample of participants (and over-sampled 18–24-year-olds) from 14 of the 49 clinics in Cape Town’s public health sector using stratified random sampling (n = 2,618), was selected. We evaluated current hazardous drug and alcohol use and three domains of stressors (Personal Threats, Lacking Basic Needs, and Interpersonal Problems). Several personal threat stressors and an interpersonal problem stressor were related to sexual risk behaviors. With stressors included in the model, hazardous alcohol use, but not hazardous drug use, was related to higher rates of sexual risk behaviors. Our findings suggest a positive screening for hazardous alcohol use should alert providers about possible sexual risk behaviors and vice versa. Additionally, it is important to address a broad scope of social problems and incorporate stress and substance use in HIV prevention campaigns.  相似文献

The ‘Health Belief Model’ (HBM) identifies perception of HIV/AIDS risks, recognition of its seriousness, and knowledge about prevention as predictors of safer sexual activity. Using data from the Cape Area Panel Survey (CAPS) and hazard models, this study examines the impact of risk perception, considered the first step in HIV prevention, set within the context of the HBM and socio-economic, familial and school factors, on the timing of first sexual intercourse among youth aged 14–22 in Cape Town, South Africa. Of the HBM components, female youth who perceive their risk as ‘very small’ and males with higher knowledge, experience their sexual debut later than comparison groups, net of other influences. For both males and females socio-economic and familial factors also influence timing of sexual debut, confirming the need to consider the social embeddedness of this sexual behavior as well as the rational components of decision making when designing prevention programs.

Tailoring sexual and reproductive health services to meet the needs of people living with the human immuno-deficiency virus (HIV) is a growing concern but there are few insights into these issues where HIV is most prevalent. This cross-sectional study investigated the fertility intentions and associated health care needs of 459 women and men, not sampled as intimate partners of each other, living with HIV in Cape Town, South Africa. An almost equal proportion of women (55%) and men (43%) living with HIV, reported not intending to have children as were open to the possibility of having children (45 and 57%, respectively). Overall, greater intentions to have children were associated with being male, having fewer children, living in an informal settlement and use of antiretroviral therapy. There were important gender differences in the determinants of future childbearing intentions, with being on HAART strongly associated with women’s fertility intentions. Gender differences were also apparent in participants’ key reasons for wanting children. A minority of participants had discussed their reproductive intentions and related issues with HIV health care providers. There is an urgent need for intervention models to integrate HIV care with sexual and reproduction health counseling and services that account for the diverse reproductive needs of these populations.  相似文献

For women enrolled in prevention of mother-to-child transmission (PMTCT) programs, non-disclosure of their HIV status can be a significant barrier to sustained HIV care engagement. To explore decision-making surrounding HIV disclosure among HIV-infected pregnant women, we conducted repeated in-depth interviews during pregnancy and postpartum with 20 women recruited from a PMTCT clinic in Cape Town, South Africa. Three domains were examined using thematic analysis: (1) disclosure experiences, (2) challenges associated with partner disclosure, and (3) implications of nondisclosure. All women had disclosed to someone by the time of the baby’s birth, typically limiting their disclosure to trusted individuals. Only half of participants disclosed to the father of the child. Nondisclosure, particularly to partners, was a significant source of worry and stress. Women used pregnancy as an explanation for using medication and attending frequent clinic appointments, and recognized impending challenges in the postpartum period when this excuse would no longer apply. Results suggest that PMTCT programs have a key role to play in helping individuals to make decisions about HIV disclosure, and assisting patients to navigate the disclosure process, especially with partners.  相似文献

South Africa has the highest number of HIV-1-infected individuals in the world, with HIV-1 subtype C prevailing. However, HIV-1 subtype C accessory genes are rarely characterized in the country. These genes are important for establishing viral pathogenesis. The Vif protein has been shown to counteract the antiretroviral activity of APOBEC3G/F cytidine deaminases. In this study an additional 50 HIV-1 vif sequences are characterized. These include 48 HIV-1 subtype C and 2 HIV-1 subtype B sequences. Highly conserved HIV-1 subtype C motifs are outlined. The previously identified RLRR (90-93) motif does not seem to be conserved among our newly analyzed sequences. Conserved motifs can be useful for developing new vaccine strategies or antiretroviral drugs.  相似文献

HIV/AIDS and intimate partner violence (IPV) are growing public health concerns in South Africa. Knowledge about adult men’s perpetration of IPV and links between HIV risk behaviours and IPV is limited. Respondent driven sampling was used to recruit men who have multiple concurrent female sexual partners. Forty-one percent of the 428 recruited men had perpetrated IPV. Inconsistent condom use was associated with physical IPV; experiencing a symptom of a sexually transmitted infection and engaging in transactional sex were associated with physical and sexual IPV; problem alcohol use was associated with physical, and any IPV, but not sexual IPV; having five or more partners was associated with sexual IPV; perceptions of partners’ infidelity were associated with physical and any IPV. HIV risk reduction interventions among men, especially those with multiple female sex partners, should incorporate strategies to change the underlying construction of masculinity that combines the anti-social and risky behaviours of IPV perpetration, inconsistent condom use, transactional sex and heavy alcohol consumption.  相似文献

Couples-based voluntary HIV counseling and testing (CVCT) allows couples to receive their HIV test results together and has been demonstrated to be effective in reducing HIV transmission, increasing and sustaining condom use, and reducing sexual risk-taking among at-risk heterosexual couples. However, the acceptability of CVCT among MSM has yet to be evaluated in an African setting. The results from seven focus group discussions and 29 in-depth interviews conducted in Cape Town, South Africa exhibit overwhelmingly high acceptance of CVCT. Participants were attracted to the counseling components of the service, stating that these would allow for the couple to increase their commitment and to explore methods of how to effectively reduce their risk of acquiring or transmitting HIV in the presence of a trained counselor. These results suggest CVCT would be highly welcomed and could work to fill the significant lack of services available and accessible to MSM couples in Cape Town.  相似文献

Alcohol use may have significant negative impacts on individuals’ ability to remain adherent to antiretroviral therapy (ART), and may also yield other negative psychosocial, health-related, and behavioral outcomes. In addition, false beliefs about the consequences of mixing alcohol with ART use may cause individuals to avoid taking ART when drinking (alcohol-related ART avoidance). Although research conducted in the U.S. and Europe has reported on alcohol-ART avoidance, the current study presents among the first quantitative evidence of alcohol-related intentional ART nonadherence in South Africa. Patients receiving ART from a community clinic in Cape Town (N?=?441) completed anonymous surveys of alcohol use, ART adherence, and alcohol-ART avoidance. Results showed that 292 (66%) participants reported current alcohol use; 25% who use alcohol believed that people who drink should stop taking ART when they are drinking and 24% stop their own ART when drinking. Alcohol-ART avoidance mediated the association between alcohol use and ART adherence. Results were robust when controlling for participant age, gender, current care status, and first- versus second-line ART. We found alcohol-ART avoidance may threaten successful ART in South Africa. Corrective messages that take a harm reduction approach to maximize ART adherence when drinking should be implemented in existing clinical services.  相似文献

HIV prevalence and risk behaviour among foreign migrants in South Africa has not been explored. This paper describes the effectiveness of respondent-driven sampling (RDS) to recruit foreign migrant women residing in Cape Town, reports HIV prevalence, and describes key characteristics among them. We conducted a biological and behavioural surveillance survey using RDS. After written informed consent, participants completed an audio computer assisted self-interview and provided a dried blood sample for HIV analysis. HIV prevalence was estimated to be 7 % (CI 4.9–9.5) among 935 women. HIV sero-positivity was associated with older age (p = 0.001), country of origin (p < 0.000), being unmarried (p < 0.000), having lived in South Africa for 3–5 years (p = 0.023), sexual debut at ≥15 years (p = 0.047), and having used a condom at last sex with a main partner (p = 0.007). Few women reported early sexual debut, or multiple sexual partners. RDS was successful in recruiting foreign migrant women.  相似文献

One in three new cases of HIV in South Africa is among adolescents. Given that adolescents are particularly affected, scalable, and cost-effective prevention programs are urgently needed. This study aims to identify opportunities to integrate technology into youth HIV prevention efforts. In 2012, 1107 8th–11th graders completed a paper-and-pencil survey. Respondents were enrolled in one of three public high schools in Langa, a lower income community in Cape Town, South Africa. Eighty-nine percent of respondents have used text messaging (SMS) and 86% have gone online. If an HIV prevention program was offered online, 66% of youth would be somewhat or extremely likely to access it; slightly fewer (55%) felt the same about SMS-based programming. In comparison, 85% said they would be somewhat or extremely likely to access a school-based HIV prevention program. Interest in Internet- (60%) and SMS-based (54%) HIV prevention programming was similar for youth who had a self-appraised risk of HIV compared to youth who appraised their risk to be lower, as it was for youth who were tired of hearing messages about HIV prevention. Technology use is common – even among high school students who live in lower income communities. At the same time, these data reveal that it is not uncommon for youth to be tired of hearing messages about HIV prevention, and many of the typical topics key to HIV prevention have low interest levels among youth. HIV prevention researchers need to be mindful of the extent of existing programming that youth are exposed to. Technology-based programming may be especially amenable to meeting these requirements because of its novelty especially in developing countries, and because interactive functionality can be easily integrated into the program design. Given the preference for school- and Internet-based programming, it seems that a hybrid approach is likely feasible and acceptable.  相似文献

South Africa is experiencing a growing methamphetamine problem, and there is concern that methamphetamine use may accelerate HIV transmission. There has been little research on the HIV prevention needs of methamphetamine users receiving substance abuse treatment in South Africa. This study assessed the prevalence and correlates of HIV risk behaviors among 269 methamphetamine users entering substance abuse treatment in two clinics in Cape Town. The prevalence of sexual risk behaviors was high among sexually active participants: 34 % multiple partners, 26 % unprotected intercourse with a casual partner, and 24 % sex trading for money/methamphetamine. The strongest predictor of all sexual risk behaviors was concurrent other drug use. Over half had not been HIV tested in the past year, and 25 % had never been tested, although attitudes toward HIV testing were overwhelmingly positive. This population of primarily heterosexual, non-injecting methamphetamine users is a high-risk group in need of targeted HIV prevention interventions. Substance abuse treatment is an ideal setting in which to reach methamphetamine users for HIV services.  相似文献

Gender identity plays a potentially important role contributing to HIV risk among MSM in South Africa. Where studies have included a focus on gender identity, MSM reporting gender non-conformity have been found to have a higher risk of being HIV positive than other MSM. This article examines HIV risk among gender non-conforming MSM in a sample of 316 MSM in Cape Town, South Africa. Reporting gender non-conformity was associated with higher HIV prevalence and increased HIV risk behaviour. Gender non-conformity was also associated with a higher likelihood of being unemployed and reporting low household incomes. These findings highlight the importance of gender-identity as a factor affecting access to HIV treatment, care, and prevention in South Africa and this is an issue that needs to be addressed in interventions targeting MSM populations.  相似文献

This study investigated the factors influencing whether high school teachers implemented HIV/AIDS education. The independent variables included constructs derived from expectancy value theories, teachers' generic dispositions, their training experience, characteristics of their interactive context and the school climate. We conducted a postal survey of 579 teachers responsible for AIDS education in all 193 public high schools in Cape Town. Questionnaires were completed and returned by 324 teachers (56% response rate) from 125 schools. Many teachers (222; 70%) had implemented HIV/AIDS education during 2003, and female teachers were more likely to have implemented than males (74% vs. 58%). The teacher characteristics associated with teaching HIV/AIDS were previous training, self-efficacy, student-centeredness, beliefs about controllability and the outcome of HIV/AIDS education, and their responsibility. The existence of a school HIV/AIDS policy, a climate of equity and fairness, and good school-community relations were the school characteristics associated with teaching HIV/AIDS. These findings demonstrate the value of teacher training and school policy formulation. They also demonstrate the value and importance of interventions that go beyond a sexual health agenda, focussing on broader school development to improve school functioning and school climate.  相似文献

This study examines factors influencing HIV sero-status disclosure to sex partners among a sample of 630 HIV-infected men and women with recent sexual contact attending anti-retroviral therapy (ART) clinics in Cape Town, South Africa, with a focus on sex partner type, HIV-related stigma, and ART as potential correlates. About 20% of the sample had not disclosed their HIV status to their most recent sex partners. HIV disclosure to sex partner was more likely among participants who had a steady sex partner [Adjusted odds ratio (AOR) = 2.7; 95% CI: 1.6–4.6], had a partner with known-HIV status [AOR = 7.8; 95% CI: 3.2–18.7]; perceived less stigma [AOR = 1.9; 95% CI: 1.2–2.9]; and were on ART [AOR = 1.6; 95% CI: 1.1–2.3]. Stratified analyses by the type of sex partner further reveals that stigma and ART were significantly associated with HIV disclosure within steady relationships but were not significant correlates of HIV disclosure with casual sex partners. The findings support a positive prevention strategy that emphasizes increased access to ART, and behavioral interventions to reduce casual sex partnerships for persons who are HIV-positive. Mitigating the influence of HIV stigma on HIV status disclosure particularly within steady sex partnerships is also important and may be accomplished through individual and couple counseling.  相似文献

South Africa is in the midst of a devastating HIV-AIDS epidemic and most new HIV infections occur among young adults and adolescents. The current study examined risk behaviors and HIV risk factors among young people living in a Black South African township. Using community-based outreach methods of street intercept and facility-based surveying, 113 men and 115 women age 25 and younger responded to an anonymous survey. Results showed that men (68%) and women (56%) reported HIV-related high risk sexual behaviors. Although knowledge about HIV transmission was generally high, there was evidence that misconceptions about AIDS persist, particularly myths related to HIV transmission. For young men, HIV risk factors were associated with fewer years of education, lower levels of AIDS-related knowledge, condom attitudes, and Dagga (marijuana) use. Among young women, HIV risk factors were associated with beliefs that condoms get in the way of sex and rates of unprotected vaginal intercourse. Despite adequate general AIDS knowledge and risk sensitization, South African youth demonstrated high rates of sexual practices that place them at risk for HIV infection. There is an urgent need for behavioral interventions targeted to young South Africans living in the most economically disadvantaged areas.  相似文献
