RESUMO

BACKGROUND: The prevalence and effect of polygamous relationships may have serious reproductive and /or health consequences for women. In South Africa, unlike in other sub-Saharan countries, no nationwide survey has investigated polygamy except for the 2002 HIV/AIDS population-based household survey. The aim of this study was to profile socio-demographic and behavioural characteristics associated with women in polygamous relationships in South Africa using the 2002 survey data. METHODS: The survey data were collected using a multi-stage stratified cluster randomised sampling design. Bivariate and multivariate logistic regression models were used to assess the relationship between polygamy, and selected socio-demographic and behavioural factors. RESULTS: Of 1437 women who responded to the question on polygamy, 8.3% reported being in a polygamous marriage. Women in polygamous marriages were significantly less likely to have tertiary education [OR = 0.03(95% CI: 0.00-0.28), p = 0.003], to have money for food and clothes [OR = 0.12 (95% CI: 0.06-0.27), p < 0.001], to have a sexual partner five years younger [OR = 0.10 (95% CI: 0.01-0.94), p = 0.044] or sexual partner within 5 years older or younger [OR = 0.35 (95% CI: 0.13-0.991), p = 0.032]. They were also significantly more likely to have two or more sexual partners [OR = 20.42 (95% CI: 1.10-379.89), p = 0.043]. CONCLUSION: The finding that polygamy is associated with uneducated and women of low economic means, who have relationships with older men and multiple sexual partners warrants further attention. Contemporary studies on polygamy are needed in South Africa.

RESUMO

The present study investigated the associations among alcohol use, socioeconomic status (SES), and human immunodeficiency virus (HIV) status, in the South African context. It was hypothesized that SES (predictor; measured as median split asset score) and alcohol use in the past 12 months (predictor) would interact such that current drinkers of low SES would be at an increased risk of testing HIV-positive (outcome). Nationally representative, cross-sectional survey data from 2005 (N = 16,110), 2008 (N = 13,055), and 2012 (N = 25,979) were analyzed using multinomial regression models. Current drinkers of low SES had an elevated risk of HIV infection in all survey years, ranging from a relative risk ratio (RRR) of 1.94 (95% confidence interval (CI) 1.29-3.00, t = 2.93, p = 0.002) in 2012 to RRR of 3.51 (95% CI 2.02-6.08, t = 4.47, p < 0.001) in 2008. Targeting preventive strategies to alcohol users of low SES could help reduce HIV burden and associated socioeconomic differences.

RESUMO

This paper explores the prevalence and correlates of HIV seropositive status disclosure to sexual partners by people living with HIV (PLHIV) in South Africa. Secondary analysis of the 2012 South African National HIV Prevalence, Incidence and Behaviour Survey was conducted on data obtained from 934 sexually active PLHIV aged 15 years and older who responded to the question about HIV seropositive status disclosure. Overall, a large majority of respondents (77.1 %) reported disclosing their HIV-positive status to all their current sex partners. Multiple regression analysis, after adjustments for sex, marital status and locality type, revealed that those who were living together, going steady, and those who were single were all 60 % [adjusted odds ratio (AOR) = 0.4, 95 % CIs 0.20-0.78; AOR = 0.4, 95 % CIs 0.24-0.77; and AOR = 0.4, 95 % CIs 0.19-1.00, all ps < 0.05] less likely to disclose their HIV positive status to their partners compared to those who were married. Those who lived in rural formal areas were 70 % less likely to disclose their HIV status to their partners compared to those who stayed in urban formal areas (AOR = 0.3, 95 % CI 0.17-0.69, p < 0.001). Those who had correct HIV knowledge and rejection of myths were 2.0 times more likely to disclose their HIV status to their partners compared to those who did not have correct HIV knowledge and rejection of myths (AOR = 2.0, 95 % CI 1.04-3.68, p < 0.05). In conclusion, intervention programmes which help improve HIV seropositive status disclosure are needed by PLHIV who are not married, live in rural formal areas, and have incorrect HIV knowledge and rejection of myths.

RESUMO

Literature from sub-Saharan Africa and elsewhere supports a global association between alcohol and HIV risk. However, more rigorous studies using multiple event-level methods find mixed support for this association, suggesting the importance of examining potential moderators of this relationship. The present study explores the assumptions of alcohol expectancy theory and alcohol myopia theory as possible moderators that help elucidate the circumstances under which alcohol may affect individuals' ability to use a condom. Participants were 82 individuals (58 women, 24 men) living with HIV who completed daily phone interviews for 42 days which assessed daily sexual behavior and alcohol consumption. Logistic generalized estimating equation models were used to examine the potential moderating effects of inhibition conflict and sex-related alcohol outcome expectancies. The data provided some support for both theories and in some cases the moderation effects were stronger when both partners consumed alcohol.

RESUMO

This article presents key findings from the 2012 HIV prevalence, incidence and behaviour survey conducted in South Africa and explores trends in the HIV epidemic. A representative household based survey collected behavioural and biomedical data among people of all ages. Chi-squared test for association and formal trend tests (2002, 2005, 2008 and 2012) were used to test for associations and trends in the HIV epidemic across the four surveys. In 2012 a total of 38 431 respondents were interviewed from 11 079 households; 28 997 (67.5%) of 42 950 eligible individuals provided blood specimens. HIV prevalence was 12.2% [95% CI: 11.4-13.1] in 2012 with prevalence higher among females 14.4% than males 9.9%. Adults aged 25-49 years were most affected, 25.2% [95% CI: 23.2-27.3]. HIV prevalence increased from 10.6% [95%CI: 9.8-11.6] in 2008 to 12.2% [95% CI: 11.4-13.1] in 2012 (p < 0.001). Antiretroviral treatment (ART) exposure doubled from 16.6% in 2008 to 31.2% in 2012 (p < 0.001). HIV incidence in 2012 among persons 2 years and older was 1.07% [95% CI: 0.87-1.27], with the highest incidence among Black African females aged 20-34 years at 4.5%. Sexual debut before 15 years was reported by 10.7% of respondents aged 15-24 years, and was significantly higher among male youth than female (16.7% vs. 5.0% respectively, p < 0.001). Reporting of multiple sexual partners in the previous 12 months increased from 11.5% in 2002 to 18.3% in 2012 (p < 0.001). Condom use at last sex dropped from 45.1% in 2008 to 36.2% in 2012 (p < 0.001). Levels of accurate HIV knowledge about transmission and prevention were low and had decreased between 2008 and 2012 from 31.5% to 26.8%. South Africa is on the right track with scaling up ART. However, there have been worrying increases in most HIV-related risk behaviours. These findings suggest that there is a need to scale up prevention methods that integrate biomedical, behavioural, social and structural prevention interventions to reverse the tide in the fight against HIV.

RESUMO

Theory-based sexual risk reduction interventions are often demonstrated effective, but few studies have examined the mechanisms that mediate their behavior changes. In addition, critical contextual factors, such as alcohol use, are often not accounted for by social cognitive theories and may add to the explanatory value of intervention effects. The purpose of this study is to examine the underlying mechanisms driving condom use following a brief sexual risk reduction intervention grounded in the information, motivation, behavioral skills (IMB) model of behavior change. We examined IMB theoretical constructs and alcohol-related contextual factors as potential mediators in separate models. Patients (n = 617) from an STI clinic in Cape Town, South Africa were randomly assigned to either a brief risk reduction intervention or an education-only control condition. We assessed IMB, and alcohol-related variables at baseline, 3, 6, 9, and 12 months and modeled IMB constructs and alcohol-related factors as mediators of behavior change. Results of growth-curve mediational modeling showed that 1 year after counseling, the intervention indirectly affected sexual risk behavior through alcohol-related constructs, but not IMB constructs. Alcohol use and related factors play critical roles in explaining HIV and STI risk reduction intervention effects. Interventions that directly address alcohol use as a factor in sexual risk behavior and behavior change should be the focus of future research.

RESUMO

Male condoms remain a key tool in preventing the spread of HIV and the female condom (FC) holds similar potential. Using data collected through a national cross-sectional population survey that was conducted in 2008, this report investigated the national prevalence of FC knowledge and use by sexually active males and females (n = 7,727) over the age of 15 years in South Africa, followed by a closer examination of the sexually active female population alone. Though knowledge of the FC among sexually active females over the age of 15 years (n = 4,551) was relatively high at 77.75 %, use was low at 7.16 %. The present study found statistically significant associations between knowledge or use of the FC and several demographic variables for females in South Africa. Having heard of the FC was consistently associated with locality, province, age, education level, marital status, and employment status. Use of the FC, however, was only associated with province and age group. Many demographic groups exhibited a high prevalence of knowledge but a low level of use; or conversely, a low prevalence of knowledge but a high level of use compared to their counterparts. Our findings support the need for a rigorous campaign to promote the use of FCs by women and also to increase their availability in public health sector facilities such as government clinics and hospitals in order to improve the chance of women using the FC, a cost-effective device that has the potential to protect both their rights and lives.

RESUMO

Condom use has increased significantly over the past decade among all adult age groups in South Africa, and it is widely believed to have played a major role in the recent significant decline in HIV incidence in the country, especially among young people. This study investigated the demographic, behavioural and psychosocial correlates of condom use at last sex among a national random probability sample of sexually experienced respondents aged 15 years and older (n = 7817, 42.9% males and 57.1% females) using data from the 2008 South African national HIV population-based household survey. Multivariate logistic regression analyses revealed that for both sexes, being aged 15-24 years and 25-49 years old, Black African, never married and unemployed were significantly associated with condom use at last sex. In addition, for males, condom use was associated with having had two or more sexual partners, whereas for females it was associated with living in urban formal, urban informal and rural informal areas, and having been in a current relationship for less than a year. Based on these findings, it was concluded that there is a need to further promote condom use especially among the subgroups of people with lower rates of condom use in order to reduce their risk of HIV infection.

RESUMO

BACKGROUND: South African alcohol-serving establishments (i.e., shebeens) offer unique opportunities to reduce HIV risks among men who drink. PURPOSE: To test an individual- and a social structural-level HIV prevention intervention for men who drink in shebeens. METHODS: Twelve matched pairs of township neighbourhoods were randomized to receive either (i) an HIV prevention intervention (guided by Social Action Theory) to reduce sexual risk and increase risk reduction communication in social networks, or (ii) an attention-matched control intervention that focused on the prevention of relationship violence. At the individual level, the interventions delivered skills building workshops focused on sexual risk reduction. At the social structural level, the intervention aimed to increase conversations about safer sex among men in the shebeens, distributed small media and implemented community educational events. Individual-level outcomes were assessed by following the workshop cohorts for 1 year (N = 984), and community-level outcomes were examined through cross-sectional community surveys conducted for 1 year in the shebeens (N = 9,678). RESULTS: Men in the HIV prevention workshops demonstrated greater condom use, more HIV prevention-oriented conversations and greater perceptions of safer sex norms than men in the comparison workshops. Changes at the community level demonstrated significant differences in condom use, although the pattern was not consistent over time. CONCLUSIONS: Multi-level interventions that target men who drink in South African shebeens may help reduce risks for HIV and other sexually transmitted infections.

RESUMO

South African townships have among the highest rates of HIV infection in the world. Considerable research on understanding the high rates of HIV transmission in this country has identified alcohol use as a critical factor in driving the HIV epidemic. Although the relationship between alcohol use and sexual risk-taking is well documented, less is known about how other factors, such as food insecurity, might be important in understanding alcohol's role in sexual risk-taking. Furthermore, prior research has highlighted how patterns of alcohol use and sexual risk-taking tend to vary by gender. We examined how food insecurity is related to both alcohol use and sexual risk-taking. We administered anonymous community surveys to men (n = 1,137) and women (n = 458) residing within four contiguous Black African townships outside of Cape Town, South Africa. In multivariate linear regression, we found that food insecurity was related to having higher numbers of male sex partners and condom-protected sex acts among women only. These relationships, however, were fully mediated by women's alcohol use. Among men, we found that food insecurity was negatively related to unprotected sex; that is, men with greater food security reported more unprotected sex acts. Unlike the results found among women, this relationship was not mediated by alcohol use. Food insecurity appears to be an important factor in understanding patterns of sexual risk-taking in regards to gender and alcohol use, and may serve as an important point of intervention for reducing HIV transmission rates.

RESUMO

South Africa has the highest prevalence of HIV in the world. Because living with HIV is stressful and because alcohol consumption is often used to cope with stress, we examined whether stress mediates the association between HIV status and alcohol use among adults residing in South African townships. Field workers approached pedestrians or patrons of informal alcohol-serving venues (i.e., shebeens) and invited their participation in a survey. Of the 1717 participants (98% Black, 34% women, mean age = 31 years), 82% were HIV-negative, 9% were HIV-positive, and 9% did not know their test result. Participants living with HIV reported greater perceived life stress compared to participants whose HIV status was negative or unknown. Perceived stress was associated with an increase in the frequency of alcohol use (drinking days, intoxication, and drinking in shebeens/taverns). Subsequent analyses showed that stress mediated the association between HIV status and alcohol use. These findings indicate that greater frequency of drinking days, perceived intoxication, and drinking at shebeens was associated with elevated stress levels among participants who were HIV positive. Perceived life stress mediates the association between HIV status and alcohol use. Programs to enhance stress management among HIV-positive South Africans may help to reduce alcohol consumption, which may, in turn, lead to reduced rates of HIV transmission.

RESUMO

South African townships have high HIV prevalence and a strong need for collective action to change normative sexual risk behaviors. This study investigated the relationship between perceptions of individuals about collective efficacy in the community's ability to prevent HIV and their personal HIV risk behaviors. Men (n = 1,581) and women (n = 718) completed anonymous surveys within four Black African Townships in Cape Town, South Africa from June 2008 to December 2010. Measures included demographics, alcohol use, attitudinal and behavioral norms, sexual health communications, and sexual risk behaviors. In multivariate logistic regressions, men were more likely to endorse collective efficacy if they were married, drank less often in alcohol serving establishments, believed that fewer men approve of HIV risk behaviors, talk more with others about HIV/AIDS, and had more sex partners in the past month. Women were more likely to endorse collective efficacy if they drank alcohol less often, talked more with others about HIV/AIDS, had more sex partners in the past month, but reported fewer unprotected sex acts in the past month. Community level interventions that strengthen collective efficacy beliefs will have to consider both protective and risk behaviors associated with believing that the community is ready and capable of preventing HIV.

RESUMO

HIV testing benefits those who test positive, allowing them to receive treatment, but the benefits for those who test negative remain controversial. We evaluated the impact of testing on HIV knowledge and sexual risk among men in South Africa. Men were recruited from townships outside Cape Town and completed a survey that assessed testing history, knowledge, and sexual behaviours. Among the 820 participants, 516 (63%) reported being tested (82% tested negative, 6% tested positive, and 12% unknown). Compared to those who had never been tested for HIV, men who tested for HIV were more knowledgeable about HIV transmission, but did not differ on sexual risk behaviour. Knowledge moderated the effect of testing on sexual risk such that men reported fewer sexual partners (incidence rate ratio (IRR) = 0.91, 95% CI = 0.84, 0.98) and fewer unprotected anal sex events (IRR = 0.81, 95% CI = 0.66, 1.00) if they had been tested for HIV and were knowledgeable about HIV transmission. For men testing HIV-negative, knowledge predicted fewer sexual risk behaviours. Previous HIV testing is associated with enhanced knowledge, which moderates sexual risk behaviour among South African men living in Cape Town. Results suggest that HIV testing may increase knowledge and lead to reductions in sexual risk even when results are negative.

RESUMO

BACKGROUND: Despite high HIV prevalence in transgender women in sub-Saharan Africa, to our knowledge no study presents data across the HIV care continuum for this population in the region. The aim of this study was to estimate HIV prevalence and present data to develop the HIV care continuum indicators for transgender women in three South African metropolitan municipalities. METHODS: Biobehavioural survey data were collected among sexually active transgender women in the metropolitan municipalities of Johannesburg, Buffalo City, and Cape Town, South Africa. Transgender women (aged ≥18 years, self-reporting consensual sex with a man in the 6 months before the survey) were recruited using respondent-driven sampling (RDS). An interviewer-administered questionnaire was used to determine awareness of HIV status; blood specimens were collected on dried blood spots to test for HIV antibodies, antiretroviral treatment (ART) exposure, and viral load suppression. Population-based estimates of HIV 95-95-95 cascade indicators were derived by use of individualised RDS weights with RDS Analyst software. Multivariate stepwise backward logistic regression modelling was used to determine factors associated with each cascade indicator. All eligible participants were included in the final analysis. FINDINGS: Between July 26, 2018, and March 15, 2019, we enrolled 887 sexually active transgender women: 323 in Johannesburg, 305 in Buffalo City, and 259 in Cape Town. HIV prevalence was highest in Johannesburg where 229 (74·1%) of 309 tests were positive (weighted prevalence estimate 63·3%, 95% CI 55·5-70·5), followed by Buffalo City where 121 (43·7%) of 277 were positive (46·1%, 38·7-53·6), and then Cape Town where 122 (48·4%) of 252 were positive (45·6%, 36·7-54·7). In Johannesburg, an estimated 54·2% (95% CI 45·8-62·4) of transgender women with HIV knew their positive status, in Cape Town this was 24·2% (15·4-35·8), and in Buffalo City this was 39·5% (27·1-53·4). Among those who knew their status, 82·1% (73·3-88·5) in Johannesburg, 78·2% (57·9-90·3) in Cape Town, and 64·7% (45·2-80·2) in Buffalo City were on ART. Of those on ART, 34·4% (27·2-42·4) in Johannesburg, 41·2% (30·7-52·6) in Cape Town, and 55·0% (40·7-68·4) in Buffalo City were virally suppressed. INTERPRETATION: Innovative strategies are needed to inform efforts to diagnose and to treat transgender women living with HIV promptly to achieve viral load suppression. Differentiated HIV services tailored to transgender women of race groups other than Black South African, and those with low education attainment and low outreach exposure, innovative testing, and adherence strategies should be developed to improve the HIV cascade for South African transgender women. FUNDING: The US President's Emergency Plan For AIDS Relief and US Centers for Disease Control and Prevention.

RESUMO

Population-based serological testing is important to understand the epidemiology and estimate the true cumulative incidence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to inform public health interventions. This study reports findings of a national household population SARS-CoV-2 serosurvey in people 12 years and older in South Africa. This cross-sectional multi-stage random stratified cluster survey undertaken from November 2020 to June 2021 collected sociodemographic data, medical history, behavioural data, and blood samples from consenting participants. The samples were tested for SARS-CoV-2 antibodies using the Roche ElecsysAnti-SARS-CoV-2 chemiluminescence immunoassay (CLIA) Total Antibody Test. The survey data were weighted by age, race, sex, and province with final individual weights benchmarked against the 2020 mid-year population estimates and accounted for clustering. Descriptive statistics summarize the characteristics of participants and seroprevalence. Logistic regression analyses were used to identify factors associated with seropositivity. From 13290 survey participants (median age 33 years, interquartile range (IQR) 23-46 years), SARS-CoV-2 seroprevalence was 37.8% [95% Confidence Interval (CI) 35.4-40.4] and varied substantially across the country's nine provinces, and by sex, age and locality type. In the final adjusted model, the odds of seropositivity were higher in women than in men [aOR = 1.3 (95% CI: 1.0-1.6), p = 0.027], and those living with HIV (self-report) [aOR = 1.6 (95% CI: 1.0-2.4), p = 0.031]. The odds were lower among those 50 years and older compared to adolescents 12-19 years old [aOR = 0.6 (95% CI: 0.5-0.8), p<0.001] and in those who did not attend events or gatherings [aOR = 0.7 (95% CI: 0.6-1.0), p = 0.020]. The findings help us understand the epidemiology of SARS-CoV-2 within different regions in a low-middle-income country. The survey highlights the higher risk of infection in women in South Africa likely driven by their home and workplace roles and also highlighted a need to actively target and include younger people in the COVID-19 response.

RESUMO

Alcohol use has been closely linked with HIV risk behaviors in South Africa. The places where people drink are often the same settings in which they meet new sex partners and may contribute independently to sexual risk. This current study examines the independent effects of patronizing alcohol serving establishments (shebeens) and alcohol use in predicting HIV risk behaviors. Men (n = 981) and women (n = 492) were recruited from inside shebeens and surrounding areas proximal to shebeens in eight separate neighborhoods in a Township in Cape Town, South Africa. Anonymous community surveys measured demographic characteristics, alcohol use, shebeen attendance, and sexual risk behaviors. Comparisons of 1210 (82 %) participants who patronized shebeens in the past month with 263 (18 %) participants who did not patronize shebeens demonstrated higher rates of alcohol use frequency and quantity, more sexual partners, and higher rates of vaginal intercourse without condoms for the patrons. Multiple linear regression analysis found shebeen attendance in the past month predicted greater sexual risk for HIV beyond demographic characteristics and alcohol use. Social influences and environmental factors in shebeens could be contributing to sexual risk behavior independently of alcohol consumption. Further research is needed to understand the environmental factors of shebeens that promote and influence HIV risk behaviors.

RESUMO

OBJECTIVES: The South African government recently launched a national campaign to test 15 million South Africans for HIV by 2011. Little is known about how receipt of HIV testing might influence interpersonal communication. To explore these questions, the authors examined the effects of prior HIV testing on sexual health communication among South Africans. METHODS: Adults (N=1284; 98% black, 36% women, mean age 31) residing in a South African township completed street-intercept surveys. RESULTS: Of the 1284 participants, 811 (63%) had been tested for HIV. Among those who had been tested, 77% tested negative, 12% tested positive, and 11% did not know their test result or refused to answer. Compared with those who had not been tested, participants who had been tested for HIV were more likely to communicate with community members about (a) HIV/AIDS, (b) getting tested for HIV, and (c) using condoms. Testing positive for HIV was associated with communication with sexual partners about condom use. Among participants who had been tested for HIV, exploratory analyses revealed that those who had engaged in sexual health communication with community members or sexual partners reported more condom-protected sex than those who had not engaged in sexual health communication. CONCLUSIONS: HIV testing is associated with sexual health communication among South African community members and sexual partners. Offering HIV testing to all South Africans may increase communication and lead to reductions in sexual risk.

RESUMO

BACKGROUND: Multiple recent sex partners promote the rapid spread of sexually transmitted infections (STI), including human immunodeficiency virus. Alcohol use is also closely associated with unprotected sexual behavior, but its use has not been investigated in relation to multiple recent sex partners in southern Africa. PURPOSE: To examine the combined risks of multiple recent sex partners and alcohol use among people seeking treatment for identified STI in Cape Town, South Africa. METHODS: Men (n = 529) and women (n = 210) receiving STI clinic services completed anonymous surveys of sexual behaviors and substance use over a two-month retrospective period. Sexual risk was defined by frequencies of unprotected intercourse and drinking alcohol before sexual intercourse. RESULTS: A total of 264 (31%) participants reported 2 or more sex partners in the previous 2 months; 87% of these partnerships occurred within 1 month of each other. Substantially greater multiple recent partners, including a greater fraction of sexual relationships estimated concurrently, were observed among men than women. Alcohol use was common in the sample, and drinking in sexual contexts was associated with multiple partners. Moderator analyses failed to show that alcohol use played a significant role in unprotected sex with multiple recent partners. CONCLUSIONS: Multiple recent partners and drinking appear independently related to unprotected sex, and both multiple partners and alcohol use should be targeted in human immunodeficiency virus risk reduction interventions.

RESUMO

OBJECTIVES: We examined the effects of a brief counseling intervention designed to reduce HIV risk behaviors and sexually transmitted infections (STIs) among patients receiving STI services in Cape Town, South Africa. METHODS: After randomization to either a 60-minute risk reduction counseling session or a 20-minute HIV-STI educational session, patients completed computerized sexual behavior assessments. More than 85% of the participants were retained at the 12-month follow-up. RESULTS: There were 24% fewer incident STIs and significant reductions in unprotected vaginal and anal intercourse among participants who received risk reduction counseling relative to members of the control condition. Moderator analyses showed shorter lived outcomes for heavy alcohol drinkers than for lighter drinkers. The results were not moderated by gender. CONCLUSIONS: Brief single-session HIV prevention counseling delivered to STI clinic patients has the potential to reduce HIV infections. Counseling should be enhanced for heavier drinkers, and sustained outcomes will require relapse prevention techniques. Disseminating effective, brief, and feasible behavioral interventions to those at highest risk for HIV infection should remain a public health priority.
