Correlates of HIV testing among South African women with high sexual and substance-use risk behaviours

Increasing age and duration of sex work among female sex workers in South Africa and implications for HIV incidence estimation: Bayesian evidence synthesis and simulation exercise

Introduction

In sub-Saharan Africa, accurate estimates of the HIV epidemic in female sex workers are crucial for effective prevention and care strategies. These estimates are typically derived from mathematical models that assume certain demographic and behavioural characteristics like age and duration of sex work to remain constant over time. We reviewed this assumption for female sex workers in South Africa.

Methods

We reviewed studies that reported estimates on either the age or the duration of sex work among female sex workers in South Africa. We used Bayesian hierarchical models to synthesize reported estimates and to study time trends. In a simulation exercise, we also investigated the potential impact of the "constant age and sex work duration"-assumption on estimates of HIV incidence.

Results

We included 24 different studies, conducted between 1996 and 2019, contributing 42 estimates on female sex worker age and 27 estimates on sex work duration. There was evidence suggesting an increase in both the duration of sex work and the age of female sex workers over time. According to the fitted models, over each decade the expected duration of sex work increased by 55.6% (95%-credible interval [CrI]: 23.5%-93.9%) and the expected age of female sex workers increased by 14.3% (95%-CrI: 9.1%-19.1%). Over the 23-year period, the predicted mean duration of sex work increased from 2.7 years in 1996 to 7.4 years in 2019, while the predicted mean age increased from 26.4 years to 32.3 years. Allowing for these time trends in the simulation exercise resulted in a notable decline in estimated HIV incidence rate among sex workers over time. This decline was significantly more pronounced than when assuming a constant age and duration of sex work.

Conclusions

In South Africa, age and duration of sex work in female sex workers increased over time. While this trend might be influenced by factors like expanding community mobilization and improved rights advocacy, the ongoing criminalisation, stigmatisation of sex work and lack of alternative employment opportunities could also be contributing. It is important to account for these changes when estimating HIV indicators in female sex workers.

Gender Differences in Psychosocial Predictors of Sexual Activity and HIV Testing Among Youth in Kenya

Sub-Saharan Africa (SSA) carries a disproportionate burden of HIV in the world relative to its population. Youth are at particular risk. Understanding HIV risk factors, as well as factors affecting HIV testing among SSA youth, is important given that HIV testing, linkage to care, and viral suppression are part of the global strategy to end HIV. Because young women face disparate sexual and reproductive health outcomes, exploring gender differences related to HIV risk, and testing is vital. Using existing program evaluation data from a larger project, the purpose of this study was to explore gender differences related to sexual activity and HIV testing among youth in SSA. Participant data from 581 youth ages 13–24 in Kenya was analyzed using descriptive statistics, analysis of covariance, and binomial logistic regression. Findings revealed that young men were more likely to report sexual activity than young women. Age was a predictor of sexual activity for all youth. However, among psychosocial variables, depression predicted sexual activity for young women while stress predicted sexual activity for young men. Although there were no gender differences in HIV testing after controlling for demographic and psychosocial variables, there were some differences between young women and young men with regard to predictors of HIV testing. Age and full-time self-employment predicted HIV testing among young women, while part-time self-employment, education, and substance abuse risk predicted HIV testing among young men. Findings suggest a need for gender and youth friendly strategies for addressing the HIV treatment cascade and care continuum.

Prior Exposure to Intimate Partner Violence Associated With Less HIV Testing Among Young Women

Low-income minority women are disproportionately represented among those living with HIV in the United States. They are also at risk for the SAVA (substance abuse, violence, and HIV/AIDS) syndemic issues. Women who have recently given birth are at high risk for substance use and intimate partner violence (IPV), and HIV testing is not routinely administered during the postpartum visit. We explored the relationship between substance use, IPV, and HIV testing among low-income young adult women attending Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), a federally supported nutrition program. A survey assessed substance use, relationships in particular with violence exposure, and HIV testing behavior in the past 6 months among a convenience sample of 100 women aged 18 to 30. The survey was conducted at several WIC offices in an urban setting in the Mid-Atlantic region between June and December 2015. Physical violence was the only IPV variable significantly associated (p = .022) with not being tested for HIV in the past 6 months, remaining significant even after adjusting for demographic and other significant variables (adjusted odds ratio [AOR] = 0.02; 95% confidence interval [CI] = [0.00, 0.41]). Women exposed to physical IPV or psychological IPV in the past year were significantly more likely to have ever used an illicit drug (physical IPV: 34% vs. 59%, p = .052; psychological IPV: 22% vs. 53%. p = .002). These findings between physical IPV and HIV testing history highlight the need to further understand how the context of violence affects HIV testing behaviors. Providing convenient, safe, and accessible HIV testing sites in spaces like WIC may increase HIV testing rates overall and specifically among women experiencing IPV.

Correlates of uptake of HIV testing among children and young adolescents in Akwa-Ibom state, Nigeria: a secondary data analysis of the Akwa-Ibom aids indicator survey, 2017

Background

In order to end the AIDS epidemic by 2030, there is a need to significantly reduce the rate of new infection among children and young adolescents. Identifying the correlates of testing behaviour is necessary to improve HIV testing campaigns by refining messages that target individuals in this age group. The objective of this study was to determine the correlates of HIV testing among children and young adolescents in Akwa-Ibom, Nigeria.

Methods

The outcome was a secondary data analysis of the 2017 Akwa-Ibom AIDS Indicator Survey. Data of 4037 children and young adolescents aged 0–14 years was assessed in this study. Analysis was done using STATA version 16. Chi-squared test and logistic regression models were used to measure association and its strength between uptake of HIV testing and some independent variables (child/caregiver’s age, sex, educational status, child’s location, caregiver’s knowledge of HIV and caregiver ever tested for HIV) at 5% significance level.

Results

Result showed that only 14.2% of the children and young adolescents have been tested for HIV. Previous history of blood transfusion (AOR = 5.33, 95%C.I = 2.60–10.92, P = < 0.001), caregiver’s level of education (AOR = 2.67, 95%C.I = 1.30–5.51, P = 0.008) and caregiver ever tested for HIV (AOR = 8.31, 95%C.I = 5.67–12.19, P = < 0.001) were significantly associated with uptake of HIV testing.

Conclusion

This study concludes that a large proportion of children and young adolescents in Akwa-Ibom state have never been tested for HIV. There is a need for HIV testing interventions to be targeted towards this age groups and their parents/guardian. Addressing the knowledge gap amongst caregivers especially in rural areas is crucial towards improving the effectiveness of HIV testing interventions.

Partner violence and HIV testing uptake among Ethiopian women

Guided by the Anderson Behavioral Model, the researchers in this study examined the association between emotional violence and HIV testing uptake among women, using the 2016 Ethiopian Demographic and Health Survey. Only 3,637 women between the ages of 15 and 49 years were included. In the bivariate analysis, emotional violence, reported by 42.6% of respondents, was associated with prior HIV testing. In the multiple logistic regression model, emotional violence was not associated with HIV testing uptake among women (p > 0.05). Our findings suggest that efforts to improve women's socio-economic status and decision-making autonomy may be more relevant to increasing HIV testing uptake.

Female sex workers perspectives and concerns regarding HIV self-testing: an exploratory study in Tanzania

BACKGROUND

HIV testing is a gateway to HIV care and treatment for people diagnosed with HIV and can link those with negative results to HIV preventive services. Despite the importance of HIV testing services (HTS) in HIV control, uptake of HTS among female sex workers (FSWs) across sub-Saharan Africa (SSA) remains sub-optimal. Concerns about stigma associated with sex work and fear of loss of livelihood if HIV status becomes known, are some of the restrictions for FSWs to utilize HTS offered through health care facilities. Introduction of HIV self-testing (HIVST) may mitigate some of the barriers for the uptake of HTS. This study explored the acceptability of FSWs towards the introduction of HIVST in Tanzania.

METHODS

We conducted an exploratory study employing in-depth interviews (IDI) and participatory group discussions (PGD) with FSWs in selected regions of Tanzania. Study participants were recruited through snowball sampling. Data were thematically analysed by two analysts using NVivo software. The analysis was informed by the social-ecological model and focused on factors associated with the acceptability of HIVST.

RESULTS

We conducted 21 PGD sessions involving 227 FSWs. Twenty three IDIs were conducted to complement data collected through PGD. Our study has demonstrated that FSWs are enthusiastic toward HIVST. Convenience (time and cost saved), and belief that HIVST will increase privacy and confidentiality motivated participants' support for the self-testing approach. Participants did express concerns about their ability to interpret and trust the results of the test. Participants also expressed concern that HIVST could cause personal harm, including severe distress and self-harm for individuals with a reactive test. Very likely, concern about adverse effects of HIVST was linked to the study participants' lay perception that HIVST would be provided only through unassisted modality.

CONCLUSIONS

FSWs demonstrated high enthusiasm to use the HIVST once it becomes available. Expectations for increased confidentiality, autonomy, and reduced opportunity costs were among the leading factors that attracted FSWs to HIVST. The major obstacles to the acceptability of HIVST included fear of HIV reactive test and not trusting self-diagnoses. Our findings underscore the importance of providing adequate access to counselling and referral services in conjunction with HIVST.

National HIV testing and diagnosis coverage in sub-Saharan Africa: a new modeling tool for estimating the 'first 90' from program and survey data

OBJECTIVE

HIV testing services (HTS) are a crucial component of national HIV responses. Learning one's HIV diagnosis is the entry point to accessing life-saving antiretroviral treatment and care. Recognizing the critical role of HTS, the Joint United Nations Programme on HIV/AIDS (UNAIDS) launched the 90-90-90 targets stipulating that by 2020, 90% of people living with HIV know their status, 90% of those who know their status receive antiretroviral therapy, and 90% of those on treatment have a suppressed viral load. Countries will need to regularly monitor progress on these three indicators. Estimating the proportion of people living with HIV who know their status (i.e. the 'first 90'), however, is difficult.

METHODS

We developed a mathematical model (henceforth referred to as 'Shiny90') that formally synthesizes population-based survey and HTS program data to estimate HIV status awareness over time. The proposed model uses country-specific HIV epidemic parameters from the standard UNAIDS Spectrum model to produce outputs that are consistent with other national HIV estimates. Shiny90 provides estimates of HIV testing history, diagnosis rates, and knowledge of HIV status by age and sex. We validate Shiny90 using both in-sample comparisons and out-of-sample predictions using data from three countries: Côte d'Ivoire, Malawi, and Mozambique.

RESULTS

In-sample comparisons suggest that Shiny90 can accurately reproduce longitudinal sex-specific trends in HIV testing. Out-of-sample predictions of the fraction of people living with HIV ever tested over a 4-to-6-year time horizon are also in good agreement with empirical survey estimates. Importantly, out-of-sample predictions of HIV knowledge of status are consistent (i.e. within 4% points) with those of the fully calibrated model in the three countries when HTS program data are included. The model's predictions of knowledge of status are higher than available self-reported HIV awareness estimates, however, suggesting - in line with previous studies - that these self-reports could be affected by nondisclosure of HIV status awareness.

CONCLUSION

Knowledge of HIV status is a key indicator to monitor progress, identify bottlenecks, and target HIV responses. Shiny90 can help countries track progress towards their 'first 90' by leveraging surveys of HIV testing behaviors and annual HTS program data.

Factors Affecting HIV Testing among Youth in Kenya

With the high prevalence of HIV among youth in sub-Saharan Africa, it is vital to better understand factors affecting HIV testing among this population; this is the first step in the HIV treatment cascade. The purpose of this study was to examine factors related to behavioral intentions regarding HIV testing using existing pre-test data from the HIV SEERs (Stigma-reduction via Education, Empowerment, and Research) Project, a community-based participatory research program targeting 13-24-year-olds in Kenya. It was hypothesized that HIV knowledge, social support, subjective well-being, and mental health (depression, anxiety, and stress) would serve as facilitators to HIV testing while projected stigma and substance use would serve as barriers to HIV testing. In partial support of our hypotheses, findings from logistic regression analyses revealed that HIV knowledge, substance use, depression, and social support were significant predictors of HIV testing intentions. However, HIV knowledge and substance use served as facilitators while depression and social support served as barriers. While projected stigma was correlated with HIV testing intentions, it was not a significant predictor in the regression analysis. Subjective well-being, anxiety, and stress were not significant predictors in the regression analysis. These findings have important implications for HIV testing initiatives designed for youth in Kenya as well as future research on HIV testing with this population.

Determinants of access to HIV testing and counselling services among female sex workers in sub-Saharan Africa: a systematic review

BACKGROUND

HIV testing and counselling (HTC) is an essential component for HIV prevention and a critical entry point into the HIV continuum of care and treatment. Despite the importance of HTC for HIV control, access to HTC services among female sex workers (FSWs) in sub-Saharan Africa (SSA) remains suboptimal and little is known about factors influencing FSWs' access to HTC. Guided by the client-centred conceptual framework, we conducted a systematic review to understand the facilitators and barriers influencing FSWs in SSA to access HTC services.

METHODS

A systematic search was conducted in MEDLINE, POPLINE and Web of Science databases for literature published between January 2000 and July 2017. References of relevant articles were also searched. We included primary studies of any design, conducted in SSA and published in the English language. Studies conducted in multi-sites inclusive of SSA were included only if data from sites in SSA were separately analysed and reported. Similarly, studies that included other subpopulations were only eligible if a separate analysis was done for FSWs. This review excluded papers published as systematic reviews, editorial comments and mathematical modelling. The protocol for this review is registered in the Prospective Register of Systematic Reviews (PROSPERO), registration number CRD42017062203.

RESULTS

This review shows that factors related to approachability, acceptability, availability, affordability and appropriateness of the services are crucial in influencing access to HTC services among FSWs in SSA. These factors were mediated by individual attributes such as HIV risk perceptions, awareness of the availability of HTC, and perceptions of the importance and quality of HTC services. The decision to utilise HTC was predominantly hampered by discriminatory social norms such as HIV stigma and criminalisation of sex work.

CONCLUSIONS

FSWs' access to HTC is facilitated by multiple factors, including individual awareness of the availability of HTC services, and perceived quality of HTC especially with regard to assured confidentiality. Concerns about HIV stigma and fear about discrimination due to community intolerance of sex work acted as major barriers for FSWs to seek HTC services from the facilities offering health services to the general population.

Correlates of HIV status awareness among older adults in Uganda: results from a nationally representative survey

Background

Recent evidence suggests that HIV prevalence is generally higher among older than younger persons. However, few studies have explored issues regarding HIV testing and awareness of HIV status among older persons. We explored the correlates of HIV status awareness among older adults (aged 45+ years) in Uganda.

Methods

This paper is based on secondary analysis of existing data on persons aged between 45 and 59 years from a nationally representative Uganda AIDS Indicator Survey which was conducted between February and September 2011. Records on the socio-demographics and HIV/AIDS-specific indicators for 2472 persons were extracted for analysis. Individuals were considered to be aware of their HIV status if they reported that they had tested and received their HIV test results within the past 12 months. Data analyses were done using the sample survey procedures to take into account the sampling structure of the data. Odds ratios were used to quantify the associations between receipt of HIV test results and potential factors.

Results

Of the 2472 respondents, 48% had ever tested and received their HIV test results while 23% tested and received their HIV results in the past 12 months or already knew that they are HIV positive. Individuals with the following characteristics had higher odds of being aware of their HIV status: being female (adjusted Odds Ratio (AOR) = 1.26; 95% CI: (1.04, 1.53), having high comprehensive knowledge of HIV/AIDS (AOR = 1.28; 95% CI: 1.04, 1.58), having attended secondary school education (AOR = 2.10; 95% CI: 1.47, 2.99) and engagement in high risk sexual behaviors (AOR = 1.53; 95% CI: (1.11, 2.10). A high level of stigma (holding at least three stigmatizing attitudes toward people living with HIV) was negatively correlated with awareness of HIV status (AOR =0.60; 95% CI: (0.45, 0.78).

Conclusion

Less than a quarter of older Ugandans are aware of their current HIV status. High levels of stigma and low comprehensive knowledge of HIV/AIDS remained critical barriers to HIV testing and awareness of HIV status. These findings suggest a need for innovative HIV testing strategies to increase HIV status awareness among older adults in Uganda.

Substance use and HIV infection awareness among HIV-infected female sex workers in Lilongwe, Malawi

BACKGROUND

HIV diagnosis, the first step in HIV care and treatment engagement, may be inhibited by substance use among female sex workers (FSW). We assessed the relationship between alcohol and cannabis use and lack of HIV infection awareness among HIV-infected FSW in Lilongwe, Malawi.

METHODS

From July to September, 2014, 200 FSW aged ≥18 years were enrolled using venue-based sampling to examine substance use, HIV testing history, and serostatus ascertained by HIV rapid test. We used Poisson regression with robust variance estimates to estimate the associations of alcohol and cannabis use and lack of HIV infection awareness.

RESULTS

Of the 138 HIV-infected FSW, 20% were unaware of their HIV infection, with 70% not testing within 6 months prior. According to the Alcohol Use Disorder Identification Tests (AUDIT), 55% of FSW unaware of their HIV infection reported hazardous, harmful, or dependent alcohol consumption. We observed a dose-response relationship between alcohol use and lack of HIV infection awareness, with alcohol dependency significantly associated with lack of HIV infection awareness (adjusted prevalence ratio: 3.0, 95% CI: 1.3, 6.8). Current cannabis use was uncommon (26%) among unaware HIV-infected FSW and weakly associated with lack of HIV infection awareness adjusted prevalence ratio: 1.1, 95% CI: 0.5, 2.5).

CONCLUSION

Increased levels of alcohol use is associated with lack of HIV infection awareness among HIV-infected FSW in Malawi. Frequent, consistent HIV testing integrated with alcohol reduction strategies could improve the health and infection awareness of substance-using FSW.

Young women's views on testing for sexually transmitted infections and HIV as a risk reduction strategy in mutual and choice-restricted relationships

AIM

The aim of this study was to identify relationship dynamics that influences the use of STI/HIV testing among young, urban African American women.

BACKGROUND

Increasing STI/HIV testing is a key prevention strategy, but more research is needed to identify barriers to testing for young women such as intimate partner violence (IPV).

METHODS

Thirty semi-structured interviews were conducted with African American women ages 18-24. Content analysis was used.

RESULTS

Women in choice-restricted relationships were unable to negotiate safer sex practices and testing was viewed as the best option. Women in relationships where the desire to use condoms was mutual used STI and HIV testing as a sign of trust building that preceded unprotected sex.

CONCLUSIONS

STI/HIV testing must be viewed as one strategy within a package of possible risk reduction. For those in choice-restricted relationships, clinicians should screen patients for partner abuse and provide additional support and referrals as clinically appropriate.

Rates of HIV testing and diagnosis in South Africa: successes and challenges

BACKGROUND

UNAIDS aims for 90% of HIV-positive individuals to be diagnosed by 2020, but few attempts have been made in developing countries to estimate the fraction of the HIV-positive population that has been diagnosed.

METHODS

To estimate the rate of HIV diagnosis in South Africa, reported numbers of HIV tests performed in the South African public and private health sectors were aggregated, and estimates of HIV prevalence in individuals tested for HIV were combined. The data were integrated into a mathematical model of the South African HIV epidemic, which was additionally calibrated to estimates of the fraction of the population ever tested for HIV, as reported in three national household surveys.

RESULTS

The fraction of HIV-positive adults who were undiagnosed declined from more than 80% in the early 2000s to 23.7% [95% confidence interval (95% CI) 23.1-24.3] in 2012. The undiagnosed proportion in 2012 was substantially higher in men (31.9%, 95% CI 29.7-34.3) than in women (19.0%, 95% CI 17.9-19.9). Projected probabilities of experiencing disease progression (CD4 cell count <350 cells/μl) without diagnosis are more than 50% for most HIV-positive adults over the age of 40. The fraction of HIV-positive adults who are undiagnosed is projected to decline to 8.9% by 2020 if current targets (10 million tests per annum) are met.

CONCLUSION

South Africa has made significant progress in expanding access to HIV testing, and at current testing rates, the target of 90% of HIV-positive adults diagnosed by 2020 is likely to be reached. However, uptake is relatively low in men and older adults.

The influence of relationship power dynamics on HIV testing in rural Malawi

Using the theory of gender and power (TGP) and data from the Tsogolo la Thanzi (TLT) study, we examined how relationship power shapes young people's decisions to test for HIV in rural Malawi (N=932), a high-HIV prevalence setting undergoing rapid expansions in testing services. We used generalized estimating equations (GEE) to examine associations among five constructs of relationship power (socioeconomic inequalities, relationship dominance, relationship violence, relationship unity, and mistrust), perceived risk, and receiving an HIV test over a 16-month period. The results indicate that young Malawians are testing for HIV at relatively high rates, repeatedly, and not just during pregnancy. Over the study period, 47.3% of respondents received at least one HIV test outside of TLT (range: 0-4). The GEE analysis revealed that men and women with higher levels of relationship unity were less likely to test for HIV. For men, being a victim of sexual coercion was an additional barrier to testing. Women's testing decisions were more strongly influenced by perceptions of a partner's risk for HIV than their own, whereas men relied more on self-assessments. The results highlight that testing decisions are deeply embedded within the relationship context, which should be considered in future HIV testing interventions.

Perceived vulnerability and HIV testing among youth in Cape Town, South Africa

The importance of perceived vulnerability to risk-reducing behaviors, including HIV testing, is fairly established, especially among youth in sub-Saharan Africa. Yet, the majority of studies that examined this important relationship used cross-sectional data that inherently assume that perceived vulnerability does not change. While these studies have been useful, the assumption of perceived vulnerability as time invariant is a major flaw and has largely limited the practical usefulness of this variable in AIDS prevention and programing. Using longitudinal data and applying random-effects logit models, this study makes a major contribution to scholarship by examining if changes in perceived vulnerability associate with a change to test for HIV among 857 young people in Cape Town, South Africa. Results show that female youth who changed their risk perceptions were more likely to also change to test for HIV, but the effects were completely attenuated after controlling for theoretically relevant variables. No significant relationships were observed for males. Also, females who were virgins at wave 2 but had sex between waves were significantly more likely to have changed to test for HIV. Of most importance was that sexual behavior eliminated the effects of change in risk perceptions suggesting that a change in perception may have occurred as a result of changes in sexual behavior. AIDS prevention programs must pay particular attention to helping youth become aware of their vulnerability to HIV risks, especially as these have implications for risk-reducing behaviors, especially for females who are burdened.

Levels of alcohol use and history of HIV testing among female sex workers in Mombasa, Kenya

HIV testing is a critical first step to accessing HIV care and treatment, particularly for high-risk groups such as female sex workers (FSWs). Alcohol use may be a barrier to accessing HIV services, including HIV testing. We analyzed data from a cross-sectional survey of 818 FSWs in Mombasa, Kenya, and estimated the association between different levels of alcohol use and having never tested for HIV. In multivariable analyses, higher levels of alcohol consumption were associated with having never tested for HIV (PR 1.60; 95% CI: 1.07, 2.40). Future interventions should explore whether reducing harmful drinking improves HIV testing among FSWs.

Correlates of social exclusion and negative labeling and devaluation of people living with HIV/AIDS in rural settings: evidence from a General Household Survey in Zambézia Province, Mozambique

Background

Increased HIV/AIDS knowledge and access to antiretroviral treatment (ART) have been hypothesized to decrease HIV stigma. However, stigma persists as a barrier to HIV services uptake. We studied the relationship between stigma, knowledge and attitudes towards HIV and its treatment, and confidence in the legal system (legal rights certitude).

Methods

We analyzed data from a household survey of 3749 randomly sampled female heads of households in 259 enumeration areas across 14 districts of Zambézia Province, Mozambique. The questionnaire included questions about beliefs, attitudes and behavior towards PLWHA, HIV transmission knowledge, treatment-related beliefs, and legal rights certitude. Factor analysis distinguished two stigma constructs: Negative labeling and devaluation (NLD) and social exclusion (SoE). Multivariable linear regression was used to determine the association between stigma, knowledge of HIV/AIDS, treatment-related beliefs, and legal rights certitude, while controlling for variance in socio-demographics.

Results

A 4-point increase in knowledge about HIV transmission was associated with more than a 3 unit decrease in NLD and SoE stigma scores (p<0.001). Given HIV transmission knowledge, a 25-point increase in legal rights certitude was associated with a 4.62 unit drop in NLD stigma (p<0.001); we did not detect an association between legal rights certitude and SoE stigma. Knowing at least one HIV positive person was associated with lower SoE (−3.17, 95% CI: −5.78, −0.56); no association with NLD (p = 0.1) was detected. ART efficacy belief was associated with higher NLD and lower SoE (2.90 increase and 6.94 decrease, respectively; p≤0.001).

Conclusion

Increasing knowledge about HIV transmission and access to ART are likely to reduce stigma, but neither of the two is a panacea. Raising community awareness of the legal rights of PLWHA might improve the efficacy of stigma reduction efforts. Strategies that focus on specific domains of stigma might be more effective than generic stigma reduction strategies.

Individual- and school-level correlates of HIV testing among secondary school students in Kenya

The policy framework guiding Kenya's response to the AIDS epidemic identifies voluntary counseling and testing as crucial to risk reduction and HIV-preventive activities. Yet in Kenya, as in most sub-Saharan countries, voluntary testing rates are low, especially among young people. Using hierarchical linear models, we identify both individual- and teacher/school-level factors that affect voluntary HIV testing among secondary school students in Kenya. Results indicate that adolescents are more likely to test for HIV serostatus when they are knowledgeable about testing, have been involved in HIV/AIDS activities in primary school, have been provided with HIV information in secondary school, perceive themselves as at high risk of contracting HIV or know of someone infected with or who has died from HIV/AIDS, and have ever engaged in sexual intercourse. Barriers include fear of going to testing centers and being perceived as HIV-positive. Teacher/school-level characteristics are relevant for explaining rates of HIV testing, especially among girls. To encourage testing, policymakers should attend to teacher/school-level factors as well as individual characteristics of students.

The relevance of social contexts and social action in reducing substance use and victimization among women participating in an HIV prevention intervention in Cape Town, South Africa

Objectives

To examine qualitatively how women’s social context and community mobilization (eg, mobilizing women to take social action and engaging their community in social change) influence substance use abstinence and victimization among women participating in a human immunodeficiency virus (HIV) intervention in Cape Town, South Africa.

Methods

Thirty women who had participated in a randomized controlled trial of a group-delivered intervention to address substance use, gender-based violence, and associated risk for HIV (The Women’s Health CoOp) were selected to participate in semi-structured interviews about their perceived impact of the intervention on their substance use and exposure to victimization. The Women’s CoOp intervention involved creating a new positive social environment for women within a group setting that also fostered women’s social action (eg, educating peers or family members) in the community. Interviews were analyzed using content analysis and coded to examine women’s descriptions of social contexts and social action, and the influence of these on women’s substance use abstinence and exposure to victimization.

Results

Social support (eg, via program staff and other participants) and social action (eg, engaging others in the community on issues relevant to substance use prevention or other health topics) promoted within the program, as well as outside social influences within women’s life contexts (eg, support from non-substance using family or male partners, leaving male partners or other peer relationships characterized by drug use, or finding employment) were key factors reported by women in terms of facilitating their substance use abstinence and in reducing women’s exposures to victimization.

Conclusion

Findings highlight the potential for group-delivered interventions that include mobilizing women to take social action in the larger community to be effective approaches for facilitating substance use abstinence, reductions in victimization, and ultimately, to address the intersection between substance use, violence, and HIV risk among women in this high HIV prevalence setting.

Alcohol consumption as a barrier to prior HIV testing in a population-based study in rural Uganda

Early receipt of HIV care and ART is essential for improving treatment outcomes, but is dependent first upon HIV testing. Heavy alcohol consumption is common in sub-Saharan Africa, a barrier to ART adherence, and a potential barrier to HIV care. We conducted a population-based study of 2,516 adults in southwestern Uganda from November-December 2007, and estimated the relative risk of having never been tested for HIV using sex-stratified Poisson models. More men (63.9 %) than women (56.9 %) had never been tested. In multivariable analysis, compared to women who had not consumed alcohol for at least 5 years, women who were current heavy drinkers and women who last drank alcohol 1-5 years prior, were more likely to have never been tested. Alcohol use was not associated with prior HIV testing among men. HIV testing strategies may thus need to specifically target women who drink alcohol.

Predictors of late presentation for HIV diagnosis: a literature review and suggested way forward

Early commencement of antiretroviral treatment can be beneficial and economical in the long run. Despite global advances in access to care, a significant proportion of adults presenting at HIV/AIDS care facilities present with advanced HIV disease. Understanding factors associated with late presentation for HIV/AIDS services is critical to the development of effective programs and treatment strategies. Literature on factors associated with late presentation for an HIV diagnosis is reviewed. Highlighted is the current emphasis on socio-demographic factors, the limited exploration of psychosocial correlates, and inconsistencies in the definition of late presentation that make it difficult to compare findings across different studies. Perspectives based on experiences from resource limited settings are underreported. Greater exploration of psychosocial predictors of late HIV diagnosis is advocated for, to guide future intervention research and to inform public policy and practice targeted at 'difficult to reach' populations.

Adding fuel to the fire: alcohol's effect on the HIV epidemic in Sub-Saharan Africa

Alcohol consumption adds fuel to the HIV epidemic in sub-Saharan Africa (SSA). SSA has the highest prevalence of HIV infection and heavy episodic drinking in the world. Alcohol consumption is associated with behaviors such as unprotected sex and poor medication adherence, and biological factors such as increased susceptibility to infection, comorbid conditions, and infectiousness, which may synergistically increase HIV acquisition and onward transmission. Few interventions to decrease alcohol consumption and alcohol-related sexual risk behaviors have been developed or implemented in SSA, and few HIV or health policies or services in SSA address alcohol consumption. Structural interventions, such as regulating the availability, price, and advertising of alcohol, are challenging to implement due to the preponderance of homemade alcohol and beverage industry resistance. This article reviews the current knowledge on how alcohol impacts the HIV epidemic in SSA, summarizes current interventions and policies, and identifies areas for increased research and development.

Factors related to HIV-testing behavior and interest in testing in Namibia

HIV testing remains an important part of HIV prevention and treatment programs. Interventions to encourage testing may be more effective if they can be tailored to audiences with different readiness for testing. We sought to determine characteristics differentiating people who had tested from those who had not but were interested, and people who were interested from people who had not tested and were not interested in testing. We analyzed survey data from 2671 adults in Namibia, investigating demographic, psychosocial, interpersonal, behavioral, and access to care-related factors that might differentiate the groups. Findings indicated that the interested group differed from the not interested group on factors such as knowledge of testing locations and about HIV medications, higher perceived susceptibility for getting HIV, lower stigma toward people with HIV, and more positive interpersonal factors like more social support and discussion about HIV. The tested group differed from the interested group on factors relating to life stage and socioeconomic status, such as being older, more educated, having more access to amenities, being less likely to be a student, and more likely to be living with a sexual partner, along with access-related factors such as access to counseling resources and testing clinics. Consistent with results from stage-based behavior change studies, interest in HIV testing among the untested may be related more to knowledge, attitudes, and social openness about HIV, while testing behavior among the interested may be related more to socioeconomic and access-related barriers. As such, interventions tailored for these different audiences may be more effective than a single intervention to promote testing.

Factors related to past HIV testing among South African non-injection drug users

South Africa has some of the highest estimates of human immunodeficiency virus (HIV) in the world, with a prevalence of 21.5%. Despite this, based on population-level data, 39% of sexually active South Africans have never been tested for HIV. Non-injection drug users (NIDUs) are a high-risk and increasingly prevalent group in South Africa. However, few studies have examined HIV test utilization among high-risk groups such as drug users in South Africa. The study was conducted in Pretoria, South Africa between 2002 and 2006. Of the 382 individuals surveyed, 31% had been tested for HIV in the past. Results indicate that females and older individuals were significantly more likely to have been tested for HIV at some point in the past, while individuals who did not know someone with HIV/AIDS as well as individuals who are unsure of their risk of HIV infection were significantly less likely to have ever accessed testing. Identification of these subgroups has implications for the development of targeted interventions to promote greater HIV testing among at-risk groups in South Africa.

Factors associated with HIV testing history and HIV-test result follow-up among female sex workers in two cities in Yunnan, China

BACKGROUND

The majority of people living with HIV/AIDS in China are unaware of their serostatus, and increasing the utilization of HIV testing may help to control the epidemic.

METHODS

This longitudinal study was conducted among female sex workers (FSWs) in 2 cities in Yunnan Province, China. Participants were surveyed in face-to-face interviews and tested for HIV and STDs. Factors associated with HIV-testing history and HIV-test follow-up were analyzed.

RESULTS

Of the 1642 study participants, 291 (17.7%) had been previously tested and 868 (52.9%) returned for post-test follow-up. Factors associated with having a previous HIV test included attending the Kaiyuan study (aOR: 4.9, 95% CI: 2.3-10.1), ≥ 9 years of schooling (aOR: 10.9, 95% CI: 2.6-45.5), <5 clients in the recent week (aOR: 1.7, 95% CI: 1.2-2.3), having a regular sexual partner (aOR: 1.9, 95% CI: 1.4-2.5), illegal drug use history (aOR: 2.2, 95% CI: 1.5-3.1), pelvic pain in the past 12 months (aOR: 1.9, 95% CI: 1.1-3.6), HIV-seropositivity (aOR: 1.8, 95% CI: 1.2-2.8), and high perception of HIV risk (aOR: 1.5, 95% CI: 1.1-2.2). FSWs who had ≥ 9 years of schooling (aOR: 1.4, 95% CI: 1.1-1.9), had <5 clients in the recent week (aOR: 1.3, 95% CI: 1.1-1.6), or were from another province (aOR: 1.9, 95% CI: 1.4-2.5) or city (aOR: 1.4, 95% CI: 1.1-1.8) were more likely to follow-up.

CONCLUSIONS

The low HIV-testing history and follow-up rates found in this is study is a significant public health problem as many high-risk individuals are not aware of their serostatus. Immediate action needs to be taken to increase the utilization of HIV testing services and notify people of their HIV status.

Effectiveness of an Adapted Evidence-Based Woman-Focused Intervention for Sex Workers and Non-Sex Workers: The Women's Health CoOp in South Africa

South Africa's concurrent epidemics of HIV, substance use, and gender-based violence point to the urgent need for interventions that address the intersectional nature of these issues. A community-based randomized trial assessed the efficacy of an adapted evidence-based Woman-Focused HIV intervention addressing all three issues with sex workers and non-sex workers. At 6-month follow-up, non-sex workers in the Woman-Focused intervention reported significantly lower mean numbers of days drinking alcohol in the previous 30 days, were significantly less likely to meet DSM-IV criteria for alcohol dependence, were more likely to report using a condom at last sex with a main partner, and were less likely to report sexual abuse by a main partner in the previous 90 days. Sex workers in the Woman-Focused intervention were significantly less likely to report physical abuse by a main partner. The findings suggest that gender-focused interventions can be effective for vulnerable women and should be offered more broadly.

Preliminary findings of an adapted evidence-based woman-focused HIV intervention on condom use and negotiation among at-risk women in Pretoria, South Africa

This article presents the results of a randomized trial in South Africa of an adapted evidence-based Woman-Focused intervention on condom use with primary sex partners. The preliminary findings show that regardless of HIV status, condom negotiation was significantly associated with condom use at the 3- and 6-month follow-ups. By intervention group, significant intervention effects were found at 6-month follow-up for HIV-positive and HIV-unknown status women in the Woman-Focused intervention who were more likely than women in the Standard intervention to report condom use with a primary male partner. Among HIV-positive women, those in the Woman-Focused group and those with greater sexual control were more likely to report condom use at the 6-month follow-up. The findings indicate that gender-based interventions for women may result in increased condom negotiation skills.

Health services utilization among South African women living with HIV and reporting sexual and substance-use risk behaviors

HIV health services are critical in sub-Saharan African where the burden of the HIV pandemic is devastating. Existing studies suggest that HIV-infected individuals from marginalized populations who know their status do not seek health services because they are unaware of available treatment and care options, may not understand how to access services, or have poor access to and utilization of health care services. This study examined factors associated with health service utilization in a sample of poor, underserved recently diagnosed HIV-positive South African women with sexual and substance use risk behaviors. The data were collected between June 2004 and May 2008. Primary outcomes included consultation with a medical professional and utilization of any health services since learning of HIV status at 3- and 6-month follow-up assessments. The study findings suggest that denial of HIV status may be a barrier to care, leading study participants to avoid utilizing health services specific to their disease and to prefer more general medical care services. In multivariate analyses, prior use of health services, financially supporting others, and sex trading were strongly associated with health service use at follow-up assessments. The study findings suggest a reduced likelihood of health services utilization among participants who met DSM-IV criteria for drug abuse as well as participants with greater numbers of poor physical health symptoms. As an important preliminary step in examining the issue of health services utilization in sub-Saharan Africa, the findings suggest an urgent need to promote HIV prevention and early testing, to strengthen long-term HIV care services, and to increase access to services.

Substance abuse, treatment needs and access among female sex workers and non-sex workers in Pretoria, South Africa

Background

This study examined cross-sectional data collected from substance-using female sex workers (FSW) and non-sex workers (non-SW) in Pretoria, South Africa, who entered a randomized controlled trial.

Methods

Women who reported alcohol use and recently engaging in sex work or unprotected sex were recruited for a randomized study. The study sample (N = 506) comprised 335 FSW and 171 female non-SW from Pretoria and surrounding areas. Self-reported data about alcohol and other drug use as well as treatment needs and access were collected from participants before they entered a brief intervention.

Results

As compared with female non-SW, FSW were found to have a greater likelihood of having a past year diagnosis of alcohol or other drug abuse or dependence, having a family member with a history of alcohol or other drug abuse, having been physically abused, having used alcohol before age 18, and having a history of marijuana use. In addition, the FSW were more likely to perceive that they had alcohol or other drug problems, and that they had a need for treatment and a desire to go for treatment. Less than 20% of participants in either group had any awareness of alcohol and drug treatment programs, with only 3% of the FSW and 2% of the non-SW reporting that they tried but were unable to enter treatment in the past year.

Conclusion

FSW need and want substance abuse treatment services but they often have difficulty accessing services. The study findings suggest that barriers within the South African treatment system need to be addressed to facilitate access for substance-using FSW. Ongoing research is needed to inform policy change that fosters widespread educational efforts and sustainable, accessible, woman-sensitive services to ultimately break the cycle for current and future generations of at-risk South African women.
