Voluntary counselling and testing: uptake, impact on sexual behaviour, and HIV incidence in a rural Zimbabwean cohort

HIV testing uptake, enablers, and barriers among African migrants in China: A nationwide cross-sectional study

Background

African migrants in China face social, structural, and cultural barriers to human immunodeficiency virus (HIV) testing with scarce information on their HIV testing behaviours. This study estimated the prevalence of HIV testing and its social and behavioural correlates to understand how to better provide HIV testing services for African migrants living in China.

Methods

We conducted a national cross-sectional survey among adult African migrants who lived in China for more than one month between January 19 to February 7, 2021. The survey was disseminated online through six African community organizations and via participant referrals. We collected data on HIV testing behaviours and history of HIV testing, social, and cultural factors and applied univariate and multivariable logistic regression to identify testing correlates.

Results

Among a total of 1305 participants, 72.9% (n = 951/1305) tested for HIV during their stay in China and yielded a self-reported HIV prevalence of 0.4% (n = 4/951). The most common reason for HIV testing was to comply with Chinese residence policy requirements (88.5%, n = 842/951); for not testing was "no need to be tested" (79.4%, n = 281/354). We found most African migrants have experienced low acculturation stress (54.5%, n = 750/1305), low social discrimination (65.6%, n = 856/1305), have a moderate stigma towards HIV (54.3%, n = 709/1305), and low community engagement around sexual health and HIV topics. In multivariable analysis, African migrants who were students (adjusted odds ratio (aOR) = 3.36, 95% CI = 2.40-4.71), living in student dormitories (aOR = 3.86, 95% CI = 1.51-9.84), received health services in China in past year (aOR = 1.67, 95% CI = 1.25-2.23), had lifetime sexually transmitted infections (STI) testing (aOR = 1.95, 95% CI = 1.23-3.10), had HIV testing before coming to China (aOR = 13.56, 95% CI = 9.36-19.65), and those engaged in community discussions of HIV and sexual health (aOR = 2.77, 95% CI = 1.31-5.83) were more likely to test for HIV in China.

Conclusions

Despite 73% of African migrants having tested for HIV in China, there are unmet needs and barriers identified in our study, such as language barriers. Access to HIV knowledge and testing services were the most important enablers for testing, including studentship, past STI/HIV testing, and community discussion on sexual health. Culturally appropriate and community-based outreach programs to provide information on HIV and testing venues for African migrants might be helpful to promote testing uptake.

Individual and community-level determinates of risky sexual behaviors among sexually active unmarried men: A multilevel analysis of 2016 Ethiopian Demographic and Health Survey

Background

In Ethiopia, HIV/AIDS continues to be a major public health problem mostly due to the high prevalence of risky sexual behaviors. However, research on risky sexual behavior and its determinants among unmarried men (never married, widowed, and divorced) who are highly vulnerable to risky sexual behavior was limited. Therefore, this study aimed to assess the magnitude of risky sexual behavior and its determinants among non-married men using a nationally representative sample.

Methods

The analysis was done on 5680 sexually active unmarried men aged 15–59 years using data from the 2016 Ethiopia Demographic Health Survey (EDHS). The main outcome variable was risky sexual behavior which defined as having at least one of the following: multiple sexual partners; initiation of sex before the age of 18 years; inconsistent condom use in the last 12 months; alcohol consumption at last sex. Multivariable generalized linear mixed-effects regression was employed to identify variables associated with risky sexual behavior.

Result

The overall magnitude of risky sexual behavior was 26.9% (95% CI; 25.7, 28.0). Currently employed (AOR = 2.49, 95% CI = 1.64–3.77), history of HIV testing (AOR = 2.51, 95% C = 1.95–3.23), drinking alcohol almost every day (AOR = 5.49, 95 CI = 2.73–11.02), and using Internet daily (AOR = 1.99, 95% CI = 1.06–3.74) increase the odds of risky sexual behavior. Whereas, primary education (AOR = 0.44, 95% CI = 0.32–0.61), secondary education level (AOR = 0.46, 95% CI = 0.29–0.72) and a high proportion of community-level media exposure (AOR = 0.42, 95% CI = 0.12–0.75) decrease the odds of risky sexual behavior.

Conclusion

In general, a significant proportion of sexually active unmarried men in Ethiopia have practiced risky sexual behavior. An intervention should be designed which are against the factors found to increase the odds of risky sexual behavior to reduce the incidence of HIV and other sexually transmitted infections.

Statistical considerations for cross-sectional HIV incidence estimation based on recency test

Longitudinal cohorts to determine the incidence of HIV infection are logistically challenging, so researchers have sought alternative strategies. Recency test methods use biomarker profiles of HIV-infected subjects in a cross-sectional sample to infer whether they are "recently" infected and to estimate incidence in the population. Two main estimators have been used in practice: one that assumes a recency test is perfectly specific, and another that allows for false-recent results. To date, these commonly used estimators have not been rigorously studied with respect to their assumptions and statistical properties. In this article, we present a theoretical framework with which to understand these estimators and interrogate their assumptions, and perform a simulation study and data analysis to assess the performance of these estimators under realistic HIV epidemiological dynamics. We find that the snapshot estimator and the adjusted estimator perform well when their corresponding assumptions hold. When assumptions on constant incidence and recency test characteristics fail to hold, the adjusted estimator is more robust than the snapshot estimator. We conclude with recommendations for the use of these estimators in practice and a discussion of future methodological developments to improve HIV incidence estimation via recency test.

Social-Cognitive Determinants of HIV Testing Among Tuberculosis Infected Patients in Kassala State, Sudan

Background: Use of HIV testing and counselling (HTC) services remains low among TB patients in Sudan. Identifying the social-cognitive (sub) determinants associated with HTC uptake is essential before developing interventions to promote uptake. This study aims to assess the sub-determinants of intention to use and actual behaviour of using HTC services among TB patients in Sudan and to ascertain the most relevant beliefs to inform future interventions. Methods: A cross-sectional study was carried out in five health facilities selected randomly in Kassala State. First, a small elicitation study (N = 25) was conducted to inform the Reasoned Action Approach (RAA) based questionnaire. A total of 411 TB patients completed the survey questionnaire. Confidence Interval Based Estimation of Relevance analysis (CIBER) was employed to establish the sub-determinants' relevance. Result: The studied beliefs explained 38-52% of the variance in the intention and 20-35% in the behaviour variance. The beliefs that "Using HTC services increases my fear of being tested positive for HIV" and "Using HTC services increases my fear of losing my partner if I have a positive test result" were negatively associated with intentions and use of HTC services; and both were highly relevant for intervention. The belief "If I use HTC services, I would know my HIV status" was positively associated with intentions and use of HTC services. However, it was less relevant for intervention. Perceived susceptibility to HIV infection was not associated with intention and only weakly associated with use of HTC services. Its relevance was low for intervention. Conclusions: The study showed that the social-cognitive beliefs (sub-determinants) vary in their relationship with the intention and use of HTC services among TB patients; with variable relevance for intervention. Interventions to enhance the use of HTC services should address the most relevant beliefs to maximise the effectiveness of interventions. Further studies are needed to identify other relevant sub-determinants of HTC use behaviour.

Factors Influencing Utilization of HIV Testing Services among Boda-Boda Riders in Kabarole District, Southwestern Uganda: A Cross-Sectional Study

Background

HIV testing is an important step for entry and linkage into HIV care. Utilization of HIV testing services among transport workers may be challenging, because of the mobile nature of their jobs. We assessed utilization of HIV testing services and identified factors influencing the utilization of HIV testing services among motorcycle taxi (boda-boda) riders in Fort Portal Municipality, Kabarole District, Southwestern Uganda.

Methods

We conducted a cross-sectional study among boda-boda riders, aged 18 years and above, from July 15 to July 29, 2020. We recruited participants through simple random sampling. Data were captured using a self-administered questionnaire. Binary logistic regression was used to identify factors associated with utilization of HIV testing services.

Results

Of the 315 participants who received questionnaires, 305 (97%) responded. The mean age of the participants was 32 (±7.1) years and ranged from 18 to 55 years. Of the 305 participants, 238 reported having taken an HIV test and received results in the past 12 months, for an HIV testing utilization rate of 78.0% (95% CI: 73.0–82.6%). In multivariable analysis, participants who were less likely to utilize HIV testing services were those aged ≥30 years (aOR = 0.33; 95% CI: 0.16–0.70, P = 0.004) and those who had HIV-related stigma (aOR = 0.27; 95% CI: 0.08–0.88, P = 0.030). Participants who were more likely to utilize HIV testing services were those who knew HIV status of their primary partners (aOR = 4.23; 95% CI: 1.24–14.49, P = 0.022) and those who had good knowledge on HIV/AIDS (aOR = 3.94; 95% CI: 1.65–9.41, P = 0.002).

Conclusions

Utilization of HIV testing services among the boda-boda riders in Fort Portal Municipality, Southwestern Uganda, was high. More efforts should focus on targeting older boda-boda riders for HIV testing, reduction of HIV-related stigma, improving knowledge on HIV/AIDS, and encouraging communication and disclosure between partners, in order to consolidate the gains made in HIV testing services in this bridge population.

eTest: a limited-interaction, longitudinal randomized controlled trial of a mobile health platform that enables real-time phone counseling after HIV self-testing among high-risk men who have sex with men

BACKGROUND

HIV disproportionately affects men who have sex with men (MSM) in the USA, and new infections continue to increase, particularly among African American (AA) and Hispanic/Latino (H/L) MSM. Rates of HIV testing are particularly low among AA and H/L MSM, and innovative approaches to encourage testing may help address high incidence in these men. HIV self-testing (HST) may be an important tool for increasing rates and frequency of testing. HST may be particularly well-suited for AA and H/L MSM, given that stigma and mistrust of medical care contribute to low testing rates. Despite its promise, however, many are concerned that HST does not sufficiently connect users with critical post-testing resources, such as confirmatory testing and care among those who test positive, and that these limitations may result in delayed linkage to care.

METHODS

We developed a mobile health platform (eTest) that monitors when HST users open their tests in real time, allowing us to provide timely, "active" follow-up counseling and referral over the phone. In this study, 900 high-risk MSM (with targets of 40% AA, 35% H/L) who have not tested in the last year will be recruited from social media and other gay-oriented websites in several major cities. Over 12 months, participants will be randomly assigned to receive (1) HST with post-test phone counseling and referral (eTest condition), (2) HST without active follow-up (standard condition), or (3) reminders to get tested for HIV at a local clinic (control) every 3 months. Primary outcomes include rates of HIV testing, receipt of additional HIV prevention services, and PrEP initiation verified by clinical medical records.

DISCUSSION

This study tests whether providing more active counseling and referral after HST encourages more regular HIV testing and engagement with other prevention services among MSM, compared to more passive approaches or clinic-based testing alone. It will also explore the cost-effectiveness and emotional/behavioral effects of these two strategies.

Perceived Knowledge of HIV-Negative Status Increases Condom Use Among Female Sex Workers in Zambian Transit Towns

Knowledge of HIV status is a necessary pre-condition for most HIV interventions, including treatment as well as biomedical and behavioral prevention interventions. We used data from a female sex worker (FSW) cohort in three Zambian transit towns to understand the effect that knowledge of HIV status has on FSWs' HIV risk-related sexual behaviors with clients. The cohort was formed from an HIV self-testing trial that followed participants for 4 months. Participants completed three rounds of data collection at baseline, 1 month, and 4 months where they reported their perceived knowledge of HIV status, number of clients on an average working night, and consistent condom use with clients. We measured the effect of knowledge of HIV status on participants' sexual behaviors by using linear regression models with individual fixed effects. The majority of the 965 participants tested for HIV at least once during the observation period (96%) and changed their knowledge of HIV status (79%). Knowledge of HIV status did not affect participants' number of clients, but it did affect their consistency of condom use. Compared with unknown HIV status, knowledge of HIV-negative status significantly increased participants' consistent condom use by 8.1% points [95% confidence interval (CI): 2.7–13.4, p = 0.003] and knowledge of HIV-positive status increased participants' consistent condom use by 6.1% points (95% CI: −0.1 to 12.9, p = 0.08); however, this latter effect was not statistically significant. FSWs in Zambia engaged in safer sex with clients when they learned their HIV status. The expansion of HIV testing programs may serve as a behavioral HIV prevention measure among FSWs.

Testing and testing positive: childhood adversities and later life HIV status among Kenyan women and their partners

Background

Adverse childhood experiences are a critical feature of lifelong health. No research assesses whether childhood adversities predict HIV-testing behaviors, and little research analyzes childhood adversities and later life HIV status in sub-Saharan Africa.

Methods

We use regression models with cross-sectional data from a representative sample (n = 1974) to analyze whether adverse childhood experiences, separately or as cumulative exposures, predict reports of later life HIV testing and testing HIV+ among semi-rural Kenyan women and their partners.

Results

No significant correlation was observed between thirteen cumulative childhood adversities and reporting prior HIV testing for respondent or partner. Separately, childhood sexual abuse and emotional neglect predicted lower odds of reporting having previously been tested for HIV. Witnessing household violence during one's childhood predicted significantly higher odds of reporting HIV+. Sexual abuse predicted higher odds of reporting a partner tested HIV+.

Conclusions

Preventing sexual abuse and household violence may improve HIV testing and test outcomes among Kenyan women. More research is required to understand pathways between adverse childhood experiences and partner selection within Kenya and sub-Saharan Africa, and data presented here suggest understanding pathways may help improve HIV outcomes.

HIV prevention among youth: A randomized controlled trial of voluntary counseling and testing for HIV and male condom distribution in rural Kenya

OBJECTIVE

Voluntary Counseling and Testing for HIV (VCT) and increasing access to male condoms are common strategies to respond to the HIV/AIDS pandemic. Using biological and behavioral outcomes, we compared programs to increase access to VCT, male condoms or both among youth in Western Kenya with the standard available HIV prevention services within this setting.

DESIGN

A four arm, unblinded randomized controlled trial.

METHODS

The sample includes 10,245 youth aged 17 to 24 randomly assigned to receive community-based VCT, 150 male condoms, both VCT and condoms, or neither program. All had access to standard HIV services available within their communities. Surveys and blood samples for HSV-2 testing were collected at baseline (2009-2010) and at follow up (2011-2013). VCT was offered to all participants at follow up. HSV-2 prevalence, the primary outcome, was assessed using weighted logistic regressions in an intention-to-treat analysis.

RESULTS

For the 7,565 respondents surveyed at follow up, (effective tracking rate = 91%), the weighted HSV-2 prevalence was similar across groups (control group = 10.8%, condoms only group = 9.1%, VCT only group = 10.2%, VCT and condoms group = 11.5%). None of the interventions significantly reduced HSV-2 prevalence; the adjusted odds ratios were 0.87 (95% CI: 0.61-1.25) for condoms only, 0.94 (95% CI: 0.64-1.38) for VCT only, and 1.12 (95% CI: 0.79-1.58) for both interventions. The VCT intervention significantly increased HIV testing (adj OR: 3.54, 95% CI: 2.32-5.41 for VCT only, and adj OR: 5.52, 95% CI: 3.90-7.81 for condoms and VCT group). There were no statistically significant effects on risk of HIV, or on other behavioral or knowledge outcomes including self-reported pregnancy rates.

CONCLUSION

This study suggests that systematic community-based VCT campaigns (in addition to VCT availability at local health clinics) and condom distribution are unlikely on their own to significantly reduce the prevalence of HSV-2 among youth.

Is knowledge of HIV status associated with sexual behaviours? A fixed effects analysis of a female sex worker cohort in urban Uganda

INTRODUCTION

Female sex workers (FSWs) have strong economic incentives for sexual risk-taking behaviour. We test whether knowledge of HIV status affects such behaviours among FSWs.

METHODS

We used longitudinal data from a FSW cohort in urban Uganda, which was formed as part of an HIV self-testing trial with four months of follow-up. Participants reported perceived knowledge of HIV status, number of clients per average working night, and consistent condom use with clients at baseline, one month, and four months. We measured the association between knowledge of HIV status and FSWs' sexual behaviours using linear panel regressions with individual fixed effects, controlling for study round and calendar time.

RESULTS

Most of the 960 participants tested for HIV during the observation period (95%) and experienced a change in knowledge of HIV status (71%). Knowledge of HIV status did not affect participants' number of clients but did affect their consistent condom use. After controlling for individual fixed effects, study round and calendar month, knowledge of HIV-negative status was associated with a significant increase in consistent condom use by 9.5 percentage points (95% CI 5.2 to 13.5, p < 0.001), while knowledge of HIV-positive status was not associated with a significant change in consistent condom use (2.5 percentage points, 95% CI -8.0 to 3.1, p = 0.38).

CONCLUSIONS

In urban Uganda, FSWs engaged in safer sex with clients when they perceived that they themselves were not living with HIV. Even in communities with very high HIV prevalence, the majority of the population will test HIV-negative. Our results thus imply that expansion of HIV testing programmes may serve as a behavioural HIV prevention measure among FSWs.

Longitudinal effects of home-based HIV self-testing on well-being and health empowerment among men who have sex with men (MSM) in the United States

HIV self-test (HST) kits have been available for purchase directly by consumers since 2012. However, public health and prevention programs have been slow to adopt self-testing as a strategy for improving testing rates and regularity, in part due to concerns about its effects on the well-being of users and lack of follow-up. This study explored whether there were differences in several constructs related to well-being, including health-related quality of life, social support, health empowerment, and emotional distress, across those who used HSTs versus tested at a clinic over time. Data were drawn from a longitudinal randomized controlled trial exploring methods of encouraging HIV testing (clinic-based, regular home delivery of HSTs) and providing follow-up afterward. Results showed that using HST in a given month was not associated with changes in either distress or well-being that same month. Although social support was lower in months when HST was used (versus clinic-based testing), participants reported that engaging in other health behaviors (e.g., Healthy diet, exercise) were more important in months they used HST compared to testing in a clinic, suggesting that HST may empower MSM to begin making other lifestyle changes that could improve their health.

HIV incidence and predictors of inconsistent condom use among adult men enrolled into an HIV vaccine preparedness study, Rustenburg, South Africa

INTRODUCTION

Understanding HIV incidence and risk behaviour among populations being considered for HIV vaccine studies is necessary for the appropriate design of trials.

METHODS

Between May 2012 and June 2015, we recruited men aged 18-49 years from urban and peri-urban areas of Rustenburg, a mining town in the North West Province, South Africa. Men who reported HIV-risk behaviour were followed for nine to 12 months to determine HIV incidence and factors associated with condom use.

RESULTS

A total of 400 HIV uninfected men were enrolled; 366 (91.5%) had at least one follow-up visit and were included in the analysis; 47.6% were under 25 years of age. HIV incidence was 1.9 per 100 person-years (95% CI: 0.79-4.56). Among heterosexual men (N = 339), 80.8% reported having vaginal intercourse with multiple partners in the past three months, among whom 74.1% reported inconsistent condom use. Sixty-eight percent reported vaginal intercourse with new female partners, of whom 40.6% reported inconsistent condom use. Over half (55.6%) of men who had sex with men (N = 27) reported anal intercourse with multiple male partners in the past three months, of whom 68.2% reported using condoms inconsistently. Men who had more than two female partners in the last three months (n = 121) were more likely to use condoms inconsistently (aOR 4.31, 95% CI: 1.34-13.8); in contrast, those with more than one new female sex partner (aOR 0.13, 94% CI 0.04-0.44), and whose sexual debut was after 19 years of age (aOR 0.39, 95% CI: 0.15-1.01) were less likely to use condoms inconsistently.

CONCLUSION

HIV incidence was low and similar to other studies of heterosexual men in South Africa. To identify men at high risk for HIV for enrolment in prevention trials, future researchers may need to focus on those who report early sexual debut and who report having multiple sexual partners. Men in newer relationships appear to use condoms more frequently.

Prevalence and determinants of unprotected sex in intimate partnerships of men who inject drugs: findings from a prospective intervention study

Unprotected sex, common among people who inject drugs, puts them and their partners at risk of sexually transmitted infections including human immunodeficiency virus (HIV). This analysis assesses the changes in sexual risk behavior with regular female partners (RFPs), among married men who inject drugs, before and after implementation of a HIV prevention intervention, and identifies correlates of unprotected sex. People who inject drugs (PWID) were assessed at three points: baseline, preintervention follow-up visit (FV)1, and postintervention FV2. Descriptive analysis was used for reporting changes in sexual behavior over time. Generalized estimating equation assessed the population-averaged change in self-reported unprotected sex with an RFP, attributable to intervention uptake. Multivariable logistic regression determined correlates of self-reported unprotected sex with an RFP at FV2. Findings suggest that the proportion of men reporting any unprotected sex remained high (baseline = 46.0%, FV1 = 43.5%, FV2 = 37.0%). A reduction was observed in unprotected sex after the intervention phase, but this could not be attributed to uptake of the intervention. Higher odds of self-reported unprotected sex with an RFP in the past three months at FV2 were associated with self-reported unprotected sex at baseline, living with family, and being HIV-negative. Married male PWID should receive counseling for safe sex with RFPs, especially those who are HIV-negative and live with their families.

Impact of HIV knowledge and stigma on the uptake of HIV testing - Results from a community-based participatory research survey among migrants from sub-Saharan Africa in Germany

Background

In 2015, 3,674 new HIV diagnoses were notified in Germany; 16% of those newly diagnosed cases originated from sub-Saharan Africa (sSA). One quarter of the newly diagnosed cases among migrants from sSA (MisSA) are notified as having acquired the HIV infection in Germany. In order to reach MisSA with HIV testing opportunities, we aimed to identify which determinants influence the uptake of HIV testing among MisSA in Germany.

Methods

To identify those determinants, we conducted a quantitative cross-sectional survey among MisSA in Germany. The survey was designed in a participatory process that included MisSA and other stakeholders in HIV-prevention. Peer researchers recruited participants to complete standardized questionnaires on HIV knowledge and testing. We conducted multivariable analyses (MVA) to identify determinants associated with ever having attended voluntary HIV testing; and another MVA to identify determinant associated with having had the last voluntary HIV test in Germany.

Results

Peer researchers recruited 2,782 participants eligible for inclusion in the MVA. Of these participants, 59.9% (1,667/2,782) previously had an HIV test. For each general statement about HIV that participants knew prior to participation in the study, the odds of having been tested increased by 19% (OR 1.19; 95%-CI: 1.11–1.27). Participants reporting that HIV is a topic that is discussed in their community had 92% higher odds of having been tested for HIV (OR 1.92; 95%-CI: 1.60–2.31). Migrants living in Germany for less than a year had the lowest odds of having had their last HIV test in Germany (OR 0.17; 95%-CI: 0.11–0.27). Additionally, MisSA 18 to 25 years (OR 0.55; 95%-CI: 0.42–0.73) and participants with varied sexual partners and inconsistent condom use (OR 0.75; 95%-CI: 0.44–0.97) had significantly lower odds of having had their last HIV test in Germany.

Discussion

Through participatory research, we were able to show that knowledge about HIV and discussing HIV in communities increased the odds of having attended HIV testing among MisSA. However, recent migrants and young sexually active people are among the least reached by testing offers in Germany. Community-based interventions may present opportunities to reach such migrants and improve knowledge and increase discussion about HIV.

HIV/AIDS workplace policy addressing epidemic drivers through workplace programs

BACKGROUND

HIV workplace policies have become an important tool in addressing the HIV Pandemic in Sub-Saharan Africa. In Zambia, the National AIDS Council has been advocating for establishing of HIV/AIDS workplace policies to interested companies, however no formal evaluation has been done to assess uptake and implementation. The study aimed to establish the existence of HIV/AIDS policies and programs in the private sector and to understand implementation factors and experiences in addressing HIV epidemic drivers through these programs.

METHODS

A mixed method assessment of the availability of policies was conducted in 128 randomly selected member companies of Zambia Federation of Employers in Lusaka. Categorized variables were analysed on Policy and programs using Stata version 12.0 for associations: Concurrently, 28 in-depth interviews were conducted on purposively sampled implementers. Qualitative results were analysed thematically before integrating them with qualitative findings.

RESULTS

Policies were found in 47/128 (36.72%) workplaces and the private sector accounted for 34/47 (72.34%) of all workplaces with a policy. Programs were available in 56/128 (43.75%) workplaces. The availability of policy was 2.7 times more likely to occur with increased size of a workplace, P value = 0.0001, (P < 0.05). Management support was 0.253 times more likely to occur in workplaces with policy, P value = 0.013, (P < 0.05) compared to those without. Having a specific budget for programs was 0.23 times more likely to occur in workplaces with a policy (P < 0.05) than those without a policy. Implementation was hindered by reduced funding, lack of time, sensitisation and lack of monitoring/evaluation systems. HIV awareness (56/56, 100%) and HIV/AIDS/Stigma (47/56, 83.93%) were the most addressed epidemic drivers through programs while Mother to Child Transmission (30/56 53.57%) and Males having sex with males were the least addressed (18/56, 32.14%).

CONCLUSION

HIV/AIDS policies exist in the private sector at a very low proportion but policy translation was very high suggesting that workplaces with polices are likely to implement programs. The eradication of HIV/AIDS by 2030, requires addressing epidemic drivers with a focus on marginalised populations, gender integration, a wellness and rights based approach within the context of the legal framework.

The association between client type and condom use with steady and unsteady partners among persons seeking HIV testing and counseling services in Kenya

BACKGROUND

Approximately 70% of global HIV infections are located in sub-Saharan Africa, and the prevalence of HIV infection in Kenya remains high.

OBJECTIVES

This study examined the association between client type (general population, commercial sex worker [CSW], or truck driver) and consistent condom use with steady and unsteady partners.

METHODS

Self-reported data included in the Kenyan Ministry of Health 2010-2011 National HIV Testing and Counseling Registry were used (n=11,567). Odds ratios (ORs) and 95% confidence intervals (CIs) were obtained using logistic regression.

RESULTS

After adjustment, CSWs and truck drivers had decreased odds of consistent condom use with steady partners compared to the general population (OR=0.52; 95% CI: 0.41-0.67 and OR=0.29; 95% CI: 0.13-0.63; respectively). CSWs had 1.95 times the odds of consistent condom use (95% CI: 1.58-2.42) and truck drivers had 0.64 times the odds of consistent condom use with unsteady partners (95% CI: 0.45-0.91) compared to the general population.

CONCLUSION

Although CSWs consistently use condoms with their unsteady partners, truck drivers do not consistently use condoms with any partners. Future HIV prevention efforts should target CSWs and truck drivers to increase consistent condom use with all partners. Such efforts may decrease the prevalence of HIV in Kenya.

The Network for Analysing Longitudinal Population-based HIV/AIDS data on Africa (ALPHA): Data on mortality, by HIV status and stage on the HIV care continuum, among the general population in seven longitudinal studies between 1989 and 2014

Timely progression of people living with HIV (PLHIV) from the point of infection through the pathway from diagnosis to treatment is important in ensuring effective care and treatment of HIV and preventing HIV-related deaths and onwards transmission of infection.  Reliable, population-based estimates of new infections are difficult to obtain for the generalised epidemics in sub-Saharan Africa.  Mortality data indicate disease burden and, if disaggregated along the continuum from diagnosis to treatment, can also reflect the coverage and quality of different HIV services.  Neither routine statistics nor observational clinical studies can estimate mortality prior to linkage to care nor following disengagement from care.  For this, population-based data are required. The Network for Analysing Longitudinal Population-based HIV/AIDS data on Africa brings together studies in Kenya, Malawi, South Africa, Tanzania, Uganda, and Zimbabwe.  Eight studies have the necessary data to estimate mortality by HIV status, and seven can estimate mortality at different stages of the HIV care continuum.  This data note describes a harmonised dataset containing anonymised individual-level information on survival by HIV status for adults aged 15 and above. Among PLHIV, the dataset provides information on survival during different periods: prior to diagnosis of infection; following diagnosis but before linkage to care; in pre-antiretroviral treatment (ART) care; in the first six months after ART initiation; among people continuously on ART for 6+ months; and among people who have ever interrupted ART.

Documenting and explaining the HIV decline in east Zimbabwe: the Manicaland General Population Cohort

PURPOSE

The Manicaland cohort was established to provide robust scientific data on HIV prevalence and incidence, patterns of sexual risk behaviour and the demographic impact of HIV in a sub-Saharan African population subject to a generalised HIV epidemic. The aims were later broadened to include provision of data on the coverage and effectiveness of national HIV control programmes including antiretroviral therapy (ART).

PARTICIPANTS

General population open cohort located in 12 sites in Manicaland, east Zimbabwe, representing 4 major socioeconomic strata (small towns, agricultural estates, roadside settlements and subsistence farming areas). 9,109 of 11,453 (79.5%) eligible adults (men 17-54 years; women 15-44 years) were recruited in a phased household census between July 1998 and January 2000. Five rounds of follow-up of the prospective household census and the open cohort were conducted at 2-year or 3-year intervals between July 2001 and November 2013. Follow-up rates among surviving residents ranged between 77.0% (over 3 years) and 96.4% (2 years).

FINDINGS TO DATE

HIV prevalence was 25.1% at baseline and had a substantial demographic impact with 10-fold higher mortality in HIV-infected adults than in uninfected adults and a reduction in the growth rate in the worst affected areas (towns) from 2.9% to 1.0%pa. HIV infection rates have been highest in young adults with earlier commencement of sexual activity and in those with older sexual partners and larger numbers of lifetime partners. HIV prevalence has since fallen to 15.8% and HIV incidence has also declined from 2.1% (1998-2003) to 0.63% (2009-2013) largely due to reduced sexual risk behaviour. HIV-associated mortality fell substantially after 2009 with increased availability of ART.

FUTURE PLANS

We plan to extend the cohort to measure the effects on the epidemic of current and future HIV prevention and treatment programmes. Proposals for access to these data and for collaboration are welcome.

Uptake of HIV testing in Burkina Faso: an assessment of individual and community-level determinants

Background

Previous studies have highlighted a range of individual determinants associated with HIV testing but few have assessed the role of contextual factors. The objective of this paper is to examine the influence of both individual and community-level determinants of HIV testing uptake in Burkina Faso.

Methods

Using nationally representative cross-sectional data from the 2010 Demographic and Health Survey, the determinants of lifetime HIV testing were examined for sexually active women (n = 14,656) and men (n = 5680) using modified Poisson regression models.

Results

One third of women (36%; 95% Confidence Interval (CI): 33–37%) reported having ever been tested for HIV compared to a quarter of men (26%; 95% CI: 24–27%). For both genders, age, education, religious affiliation, household wealth, employment, media exposure, sexual behaviors, and HIV knowledge were associated with HIV testing. After adjustment, women living in communities where the following characteristics were higher than the median were more likely to report uptake of HIV testing: knowledge of where to access testing (Prevalence Ratio [PR] = 1.41; 95% CI: 1.34–1.48), willing to buy food from an infected vendor (PR = 2.06; 95% CI: 1.31–3.24), highest wealth quintiles (PR = 1.18; 95% CI: 1.10–1.27), not working year-round (PR = 0.90; 95% CI: 0.84–0.96), and high media exposure (PR = 1.11; 95% CI: 1.03–1.19). Men living in communities where the proportion of respondents were more educated (PR = 1.23; 95% CI: 1.07–1.41) than the median were more likely to be tested.

Conclusions

This study shed light on potential mechanisms through which HIV testing could be increased in Burkina Faso. Both individual and contextual factors should be considered to design effective strategies for scaling-up HIV testing.

Reactions to Testing HIV Negative: Measurement and Associations with Sexual Risk Behaviour Among Young MSM Who Recently Tested HIV Negative

Receiving an HIV-positive test result is associated with reduced condomless anal sex (CAS), but little is known about negative test results. The recent development of the Inventory of Reactions to Testing HIV Negative confirmed that there are diverse reactions to receiving a negative test result, which have implications for risk behaviour. The goals of the current study were to validate the measure in a sample of young men who have sex with men who recently tested HIV-negative (N = 1113) and to examine its associations with CAS. Factor analysis identified four factors, three of which were the same as the original factors (Reinforced Safety, Luck, and Invulnerability) and one that was novel (Reinforced Risk). Construct validity was demonstrated with associations between subscales and constructs from the IMB model of HIV prevention. Lower Reinforced Safety and higher Luck and Reinforced Risk were associated with more CAS. Associations between Reinforced Safety and Luck with CAS were stronger for those who reported more lifetime HIV tests. Findings highlight the importance of reactions to testing HIV-negative and suggest that they become more important with repeated testing.

The effect of HIV counselling and testing on HIV acquisition in sub-Saharan Africa: a systematic review

OBJECTIVES

Annually, millions of people in sub-Saharan Africa (SSA) receive HIV counselling and testing (HCT), a service designed to inform persons of their HIV status and, if HIV uninfected, reduce HIV acquisition risk. However, the impact of HCT on HIV acquisition has not been systematically evaluated. We conducted a systematic review to assess this relationship in SSA.

METHODS

We searched for articles from SSA meeting the following criteria: an HIV-uninfected population, HCT as an exposure, longitudinal design and an HIV acquisition endpoint. Three sets of comparisons were assessed and divided into strata: sites receiving HCT versus sites not receiving HCT (Strata A), persons receiving HCT versus persons not receiving HCT (Strata B) and persons receiving couple HCT (cHCT) versus persons receiving individual HCT (Strata C).

RESULTS

We reviewed 1635 abstracts; eight met all inclusion criteria. Strata A consisted of one cluster randomised trial with a non-significant trend towards HCT being harmful: incidence rate ratio (IRR): 1.4. Strata B consisted of five observational studies with non-significant unadjusted IRRs from 0.6 to 1.3. Strata C consisted of two studies. Both displayed trends towards cHCT being more protective than individual HCT (IRRs: 0.3-0.5). All studies had at least one design limitation.

CONCLUSIONS

In spite of intensive scale-up of HCT in SSA, few well-designed studies have assessed the prevention impacts of HCT. The limited body of evidence suggests that individual HCT does not have a consistent impact on HIV acquisition, and cHCT is more protective than individual HCT.

Factors that lead to changes in sexual behaviours after a negative HIV test: protocol for a prospective cohort study in Kinshasa

Background

Considering the high percentage of couples in which one or both members are HIV negative, the frequency of transmission among non-regular partners and the probabilities of non-disclosure, attention should be paid to people getting a negative HIV test at the Voluntary Counseling and Testing (VCT). Research has shown that a negative HIV test may be followed by a change in sexual behaviours. In Sub-Saharan Africa, where most HIV infections occur, there are few studies that have analysed the factors associated with changes in sexual risk behaviours after a negative HIV test at the VCT clinic. The aim of this project is to evaluate the specific factors associated with changes in sexual behaviours, three months after a negative result in an HIV test, and to analyse the effect of counseling and testing on HIV-related knowledge of participants in an outpatient centre of Kinshasa (Democratic Republic of Congo).

Methods and design

Prospective cohort study from December 2014 until March 2016. People 15–60 year old that received VCT at Monkole Hospital (Kinshasa) were followed three months after they got a negative HIV test. In a face-to-face interview, participants replied to a baseline and a follow-up research questionnaire on HIV-related knowledge, attitudes and behaviours. At follow-up respondents were also offered a new HIV test and additional HIV counseling. Four hundred and fifteen participants completed the baseline questionnaire and 363 (87 %) came back for their 3-month follow up.

Discussion

This is the first longitudinal study in the DRC that evaluates the factors associated with changes in sexual behaviours after a negative HIV test at the VCT. Participants attending the VCT services within a clinical setting are a good study population as they can be good transmitters of preventive information for other people with no access to health facilities.

HIV-testing among female sex workers on the border between Brazil and French Guiana: the need for targeted interventions

The border between Brazil and French Guiana is a place of economic, cultural, social and sexual exchange. Female sex workers represent a high risk population for HIV in this area where sexual tourism is particularly developed. HIV testing seems to be an important element in the fight against the epidemic. Indeed, early HIV testing gives access to treatments and prevention. An HIV/AIDS knowledge, attitudes, behaviors and practices survey was conducted in 2011 among sex workers along the border between Brazil and French Guiana. A total of 213 female sex workers were interviewed. One third (31.5%) of the interviewed had never tested for HIV. Factors associated with non HIV-testing were the lack of knowledge of places where to do an HIV test, to be 30 or older, feeling at risk of HIV, not evaluating one's own risk towards HIV, and living in Oiapoque. These results clearly suggest that targeted interventions are needed to encourage and assist female sex workers to get tested regularly.

Factors influencing the uptake of voluntary HIV counseling and testing in rural Ethiopia: a cross sectional study

Background

Voluntary counseling and testing (VCT) has been one of the key policy responses to the HIV/AIDS epidemic in Ethiopia. However, the utilization of VCT has been low in the rural areas of the country. Understanding factors influencing the utilization of VCT provides information for the design of context based appropriate strategies that aim to improve utilization. This study examined the effects of socio-demographic and behavioral factors, and health service characteristics on the uptake of VCT among rural adults in Ethiopian.

Methods/design

This study was designed as a cross sectional study. Data from 11,919 adults (6278 women aged 15–49 years and 5641 men aged 15–59 years) residing in rural areas of Ethiopia who participated in a national health extension program evaluation were used for this study. The participants were selected from ten administrative regions using stratified multi-stage cluster sampling. Multivariate logistic regression analysis was performed accounting for factors associated with the use of VCT service.

Results

Overall, men (28 %) were relatively more likely to get tested for HIV than women (23.7 %) through VCT. Rural men and women who were young and better educated, who perceived having small risk of HIV infection, who had comprehensive knowledge, no stigmatization attitude and discussed about HIV/AIDS with their partner, and model-family were more likely to undergone VCT. Regional state was also strongly associated with VCT utilization in both men and women. Rural women who belonged to households with higher socio-economic status, non-farming occupation, female-headed household and located near health facility, and who visited health extension workers and participated in community conversation were more likely to use VCT. Among men, agrarian lifestyle was associated with VCT use.

Conclusions

Utilization of VCT in the rural communities is low, and socio-economic, behavioral and health service factors influence its utilization. For increasing the utilization of VCT service in rural areas, there is a need to target the less educated, women, poor and farming families with a focus on improving knowledge and reducing HIV/AIDS related stigma. Strategy should include promoting partner and community conversations, accelerating model-family training, and using alternative modes of testing.

Strategies for delivery of HIV test results in population-based HIV seroprevalence surveys: a review of the evidence

OBJECTIVES

Many population-based demographic surveys assess local and national HIV prevalence in developing countries through home-based HIV testing and counselling (HBHTC), but results are rarely returned to participants. This review gathered evidence on the feasibility and best practices of providing HIV test results during such surveys by reviewing population-based surveys that provided test results.

STUDY DESIGN

Literature review.

METHODS

This review was conducted as part of a broader literature review related to HBHTC. We present results from population-based HIV seroprevalence surveys conducted between January 1984 and June 2013.

RESULTS

We identified eighteen population-based surveys describing uptake of results when testing or results were offered in the home, four of which compare home uptake to facility-based testing. All were from Sub-Saharan Africa. More people tested and received results in HBHTC compared to facility-based testing. Uptake of test results (72%) and the percentage of the population tested (59%) was highest when testing and the provision of results were provided in the home compared to the provision of results elsewhere (41% uptake; 37% population coverage), as well as mobile/facility-based testing and the provision of results (15% uptake; 13% population coverage). Providing results the same day as testing in HBHTC produces higher uptake (97% uptake; 74% population coverage) than delayed results.

CONCLUSIONS

Inclusion of home testing and provision of HIV results to participants in national population-based surveys in Sub-Saharan Africa is possible and should be prioritized. The timing and location of testing and the provision of results during HBHTC as part of population-based surveys affects uptake of testing and population coverage.

Facilitators and Barriers to HIV Screening: A Qualitative Meta-Synthesis

Accomplishments in biomedical research and technology, combined with innovative community and clinically based interventions, have expanded HIV testing globally. However, HIV screening and receipt of results remains a challenge in some areas. To optimize the benefits of HIV screening, it is imperative that there is a better understanding of the barriers to and motivators of testing for HIV infection. This study is a meta-synthesis of the qualitative literature on HIV screening and receipt of results; 128 unique publications had implications for HIV screening and receipt of results. A socioecological perspective provided an appropriate approach for synthesizing the literature. Three levels of influence emerged: individual attributes, interpersonal attributes, and broader patterns of influence. Findings were reviewed and found to have implications for continued engagement in the HIV treatment cascade. Recommendations to enhance HIV screening and to ensure receipt of results are proposed and discussed.

Factors Associated with Ever Being HIV-Tested in Zimbabwe: An Extended Analysis of the Zimbabwe Demographic and Health Survey (2010-2011)

INTRODUCTION

Zimbabwe has a high human immunodeficiency virus (HIV) burden. It is therefore important to scale up HIV-testing and counseling (HTC) as a gateway to HIV prevention, treatment and care.

OBJECTIVE

To determine factors associated with being HIV-tested among adult men and women in Zimbabwe.

METHODS

Secondary analysis was done using data from 7,313 women and 6,584 men who completed interviewer-administered questionnaires and provided blood specimens for HIV testing during the Zimbabwe Demographic and Health Survey (ZDHS) 2010-11. Factors associated with ever being HIV-tested were determined using multivariate logistic regression.

RESULTS

HIV-testing was higher among women compared to men (61% versus 39%). HIV-infected respondents were more likely to be tested compared to those who were HIV-negative for both men [adjusted odds ratio (AOR) = 1.53; 95% confidence interval (CI) (1.27-1.84)] and women [AOR = 1.42; 95% CI (1.20-1.69)]. However, only 55% and 74% of these HIV-infected men and women respectively had ever been tested. Among women, visiting antenatal care (ANC) [AOR = 5.48, 95% CI (4.08-7.36)] was the most significant predictor of being tested whilst a novel finding for men was higher odds of testing among those reporting a sexually transmitted infection (STI) in the past 12 months [AOR = 1.86, 95%CI (1.26-2.74)]. Among men, the odds of ever being tested increased with age ≥ 20 years, particularly those 45-49 years [AOR = 4.21; 95% CI (2.74-6.48)] whilst for women testing was highest among those aged 25-29 years [AOR = 2.01; 95% CI (1.63-2.48)]. Other significant factors for both sexes were increasing education level, higher wealth status and currently/formerly being in union.

CONCLUSIONS

There remains a high proportion of undiagnosed HIV-infected persons and hence there is a need for innovative strategies aimed at increasing HIV-testing, particularly for men and in lower-income and lower-educated populations. Promotion of STI services can be an important gateway for testing more men whilst ANC still remains an important option for HIV-testing among pregnant women.

Frequency of HIV-testing and factors associated with multiple lifetime HIV-testing among a rural population of Zambian men

BACKGROUND

Across sub-Saharan Africa, men's levels of HIV-testing remain inadequate relative to women's. Men are less likely to access anti-retroviral therapy and experience higher levels of morbidity and mortality once initiated on treatment. More frequent HIV-testing by men at continued risk of HIV-infection is required to facilitate earlier diagnosis. This study explored the frequency of HIV-testing among a rural population of men and the factors associated with more frequent HIV-testing.

METHODS

We conducted a secondary analysis of a population-based survey in three rural district in Zambia, from February-November, 2013. Households (N = 300) in randomly selected squares from 42 study sites, defined as a health facility and its catchment area, were invited to participate. Individuals in eligible households were invited to complete questionnaires regarding demographics and HIV-testing behaviours. Men were defined as multiple HIV-testers if they reported more than one lifetime test. Upon questionnaire completion, individuals were offered rapid home-based HIV-testing.

RESULTS

Of the 2376 men, more than half (61%) reported having ever-tested for HIV. The median number of lifetime tests was 2 (interquartile range = 1-3). Just over half (n = 834; 57%) of ever-testers were defined as multiple-testers. Relative to never-testers, multiple-testers had higher levels of education and were more likely to report an occupation. Among the 719 men linked to a spouse, multiple-testing was higher among men whose spouse reported ever-testing (adjusted prevalence ratio = 3.02 95% CI: 1.37-4.66). Multiple-testing was higher in study sites where anti-retroviral therapy was available at the health facility on the day of a health facility audit. Among ever-testers, education and occupation were positively associated with multiple-testing relative to reporting one lifetime HIV-test. Almost half (49%) of ever-testers accepted the offer of home-based HIV-testing.

DISCUSSION

Reported HIV-testing increased among this population of men since a 2011/12 survey. Yet, only 35% of all men reported multiple lifetime HIV-tests. The factors associated with multiple HIV-testing were similar to factors associated with ever-testing for HIV. Men living with HIV were less likely to report multiple HIV-tests and employment and education were associated with multiple-testing. The offer of home-based HIV-testing increased the frequency of HIV-testing among men.

CONCLUSION

Although men's levels of ever-testing for HIV have increased, strategies need to increase the lifetime frequency of HIV-testing among men at continued risk of HIV-infection.

The Impact of Married Individuals Learning HIV Status in Malawi: Divorce, Number of Sexual Partners, and Condom Use With Spouses

This article assesses how married individuals' knowledge of HIV status gained through HIV testing and counseling (HTC) affects divorce, the number of sexual partners, and the use of condoms within marriage. This study improves upon previous studies on this topic because the randomized incentives affecting the propensity to be tested for HIV permit control for selective testing. Instrumental variable probit and linear models are estimated, using a randomized experiment administered as part of the Malawi Longitudinal Study of Families and Health (MLSFH). The results indicate that knowledge of HIV status (1) does not affect chances of divorce for either HIV-negative or HIV-positive respondents; (2) reduces the number of reported sexual partners among HIV-positive respondents; and (3) increases reported condom use with spouses for both HIV-negative and HIV-positive respondents. These results imply that individuals actively respond to information about their HIV status that they learn during HTC, invoking protective behavior against future risk of HIV/AIDS for themselves and their actual and potential sexual partners. Some limitations of this study are a small sample size for those who are HIV-positive and dependence on self-reported sexual behaviors.

Testing negative means I'm lucky, making good choices, or immune: diverse reactions to HIV test results are associated with risk behaviors

BACKGROUND

HIV testing may lead to behavioral changes among some individuals, but no scale has been developed to assess potential mechanisms.

PURPOSE

We aimed to develop and evaluate the psychometric properties of a scale to measure psychological reactions to the receipt of a negative HIV test and explore the scale's associations with unprotected anal intercourse (UAI).

METHODS

Two focus groups were conducted to develop the Inventory of Reactions to Testing HIV Negative, which was subsequently tested on 725 men who have sex with men in the New York City area.

RESULTS

Factor analyses confirmed the presence of three subscales-Reinforced Safety, Invulnerability, and Luck. Regression analyses demonstrated that the subscales interacted with HIV testing behavior to influence UAI.

CONCLUSIONS

These findings support the notion that there is heterogeneity in how individuals respond to a negative HIV test, with some individuals subsequently being influenced towards increased engagement in HIV risk behaviors.

SURPRISING RESULTS: HIV TESTING AND CHANGES IN CONTRACEPTIVE PRACTICES AMONG YOUNG WOMEN IN MALAWI

This study uses eight waves of data from the population-based Tsogolo la Thanzi study (2009-2011) in rural Malawi to examine changes in young women's contraceptive practices, including the use of condoms, non-barrier contraceptive methods and abstinence, following positive and negative HIV tests. The analysis factors in women's prior perceptions of their HIV status that may already be shaping their behaviour and separates surprise HIV test results from those that merely confirm what was already believed. Fixed-effects logistic regression models show that HIV testing frequently affects the contraceptive practices of young Malawian women, particularly when the test yields an unexpected result. Specifically, women who are surprised to test HIV positive increase their condom use and are more likely to use condoms consistently. Following an HIV-negative test (whether a surprise or expected), women increase their use of condoms and decrease their use of non-barrier contraceptives; the latter may be due to an increase in abstinence following a surprise negative result. Changes in condom use following HIV testing are robust to the inclusion of potential explanatory mechanisms, including fertility preferences, relationship status and the perception that a partner is HIV positive. The results demonstrate that both positive and negative tests can influence women's sexual and reproductive behaviours, and emphasize the importance of conceptualizing of HIV testing as offering new information only insofar as results deviate from prior perceptions of HIV status.

What motivates use of community-based human immunodeficiency virus testing in rural South Africa?

Despite substantial progress in implementing HIV testing, challenges remain in achieving widespread uptake particularly in rural resource-limited settings. We sought to understand motivations for HIV testing in a community-based HIV testing programme in rural South Africa. We conducted a questionnaire survey in participants undergoing voluntary HIV testing within an ongoing community-based integrated HIV/tuberculosis intensive case finding programme at congregate rural settings. Participants responded to a six-item non-mutually exclusive motivations survey which included the topics of feeling ill, recent HIV exposure, risky lifestyle, illness in a family member, and pregnancy. Among 2068 respondents completing the survey, 1393 (67.4%) were women, median age was 40 years (IQR 19-56), and 1235 (59.7%) were first-time testers. Among all testers, 142 (6.9%) were HIV-positive with median CD4 count was 346 cells/mm(3) (IQR 218-542). Community-based testing for HIV is acceptable and meets the needs of community members in rural South Africa. Motivations for HIV testing at the community level are complex and differ according to gender, age, site of community testing, and HIV status. These differences can be utilised to improve the focus and yield of community-based HIV screening.

Factors associated with HIV counseling and testing and correlations with sexual behavior of teachers in primary and secondary schools in Addis Ababa, Ethiopia

Background

The HIV/AIDS pandemic is a global crisis that affects the lives of millions of people. Although HIV counseling and testing (HCT) serves as the entry point for HIV prevention, treatment, and care, it remains a low priority in many settings. The aim of this study, therefore, was to assess the factors associated with HCT and their correlation with the sexual behavior of primary and secondary school teachers in Addis Ababa.

Methods

A comparative cross-sectional study was conducted among primary and secondary school teachers in Addis Ababa, Ethiopia. A multistage sampling technique was used to select a representative sample of 1,136 teachers. HCT and sexual health behavior-related data were collected using a self-administered questionnaire. Binary logistic regression was employed to examine the relationships between HCT, sociodemographics, and risky sexual behavior-related variables.

Results

Of the 1,136 eligible study participants, 1,034 (91.0%) teachers completed the self-administered anonymous questionnaire. The proportion of teachers who had ever tested for HIV was 739/1,034 (71.5%; 95% confidence interval [CI] 69.1–74.2). Multivariate logistic regression analyses showed that being male (adjusted odds ratio [AOR] 0.63; 95% CI 0.44–0.90) was associated with a 37% decrease in odds of being ever tested for HIV compared with being female. Married teachers were less likely to have had HIV testing (AOR 0.30; 95% CI 0.19–0.47) compared with unmarried teachers. Being aged ≥45 years (AOR 4.05; 95% CI 1.82–9.03), having high HCT-related knowledge (AOR 3.56; 95% CI 1.73–7.32), and having a perceived risk of HIV (AOR 1.43; 95% CI 1.04–1.96) were positively associated with HCT. Moreover, regarding the correlation of HCT with the sexual behavior of teachers, those teachers who never had HCT were more likely to have multiple sexual partners than those who had ever had HCT (AOR 1.85; 95% CI 1.08–3.15). In contrast, teachers who had ever been tested for HIV were less likely to have used condoms consistently than those who had never been tested (AOR 0.55; 95% CI 0.32–0.96).

Conclusion

No significant differences were observed between primary and secondary school teachers regarding factors associated with HCT and its correlation with sexual behavior. Gender, age, marital status, knowledge of HCT, and perceived risk were found to be factors associated with HCT uptake. Correlations between being faithful to a partner, inconsistent use of condoms, and HCT uptake of teachers were also observed. Thus, strengthening the current practice of HCT services in the education sector with due emphasis on the observed factors could play a pivotal role in bringing about positive changes in the sexual behavior of school community.

Factors Associated with Low Levels of HIV Testing among Men Who Have Sex with Men (MSM) in Brazil

The aim of this study was to assess risk factors associated with low levels of HIV testing among MSM recruited through respondent driven sampling (RDS) in Brazil. Of 3,617 participants, 48.4% had never tested previously for HIV. A logistic model indicated that younger age, lower socioeconomic class, education, poor HIV/AIDS knowledge, no history of cruising, and having been tested during the study were characteristics independently associated with low levels of previous HIV testing. The HIV testing rate among MSM in Brazil is still low in spite of the availability of a large number services providing universal and free access to HIV/AIDS diagnosis and treatment. To respond to low utilization, the authors propose a higher priority for testing for key populations such as MSM, expanded education, expanding testing sites and a welcoming and nonjudgmental environment in health services.

HIV testing is associated with increased knowledge and reductions in sexual risk behaviours among men in Cape Town, South Africa

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.

Scaling up combined community-based HIV prevention interventions targeting truck drivers in Morocco: effectiveness on HIV testing and counseling

Background

Truck drivers constitute an important bridging group in the HIV epidemic in Morocco. This study examined the effect of a community-based educational intervention in Morocco on HIV testing and counseling, in representative samples of truck drivers before (2007) and after (2012) the intervention.

Methods

Face-to-face structured interviews, adapted from UNAIDS documents, collected data on socio-demographic characteristics, HIV testing and counseling, and HIV risk behaviors in both the 2007 and 2012 surveys. Information about exposure to the intervention was also collected in the latter. Individuals exposed to the intervention were compared with those unexposed (i.e. unexposed in 2012, and all the 2007 pre-intervention sample).

Results

The 2012 group included 459 men with a median [IQR] age of 38 [31–44] years, 53% of whom reported exposure to the educational intervention. The percentage of participants tested for HIV and receiving HIV counseling in the last 12 months, was significantly higher in the 2012 group (29.6% vs 4.3% in 2007). Data from the 2012 survey confirmed a significant positive trend between being HIV tested and receiving counseling and the number of times a participant was exposed to the intervention (once: (OR = 5.17(2.38-11.25)), twice or more (OR = 19.16(10.33 - 35.53)). These results were confirmed after adjustment for employment, knowledge that the HIV test results would remain confidential, inconsistent condom use with occasional partners or sex workers, and when including individuals from 2007 considered unexposed.

Conclusions

Community-based educational interventions targeting truck drivers can be effective in increasing coverage of HIV testing and counseling, particularly if they are repeated and cover a considerable portion of this at-risk population. These results are encouraging for other countries which urgently need to implement prevention interventions for most-at-risk populations. Furthermore, they clearly show the power of community-based organization interventions in settings where resources for HIV prevention remain limited.

HIV testing of construction workers in the Western Cape, South Africa

With an infection rate estimated at 14%, the South African construction industry is one of the economic sectors most adversely affected by the HIV/AIDS pandemic. Construction workers are considered a high-risk group. The provision and uptake of voluntary counselling and testing (VCT) is critical to reducing transmission rates. This study examined the testing behaviour of site-based construction workers in terms of demographic and lifestyle risk behaviour characteristics to help inform better strategies for work-based interventions by construction firms. A total of 512 workers drawn from six firms operating on 18 construction sites in the Western Cape province participated in the study. Twenty-seven per cent of the participants reported never having been tested for HIV. Results indicate that females (aOR = 4.45, 95% CI, 1.25-15.82), older workers (aOR = 1.40, 95% CI, 1.08-1.81), permanent workers (aOR = 1.67, 95% CI, 1.11-2.50) and workers whom had previously used a condom (aOR = 1.93, 95% CI, 1.02-3.65) were significantly more likely to have been tested. Ethnicity was not significantly related to prior testing. Identification of these subgroups within the industry has implications for the development of targeted work-based intervention programmes to promote greater HIV testing among construction workers in South Africa.

Poor-quality health services and lack of programme support leads to low uptake of HIV testing in rural Mozambique

Mozambique has one of the world's highest burdens of HIV infection. Despite the increase in HIV-testing services throughout the country, the uptake has been low. To identify barriers to HIV testing we conducted a study in six rural districts in Zambézia Province. We recruited a total of 124 men and women from the community through purposeful sampling to participate in gender-specific focus group discussions about barriers to HIV testing. The participants noted three main barriers to HIV testing: 1) poor conduct by clinicians, including intentional disclosure of patients' HIV status to other community members; 2) unintentional disclosure of patients' HIV status through clinical practices; and, 3) a widespread fatalistic belief that HIV infection will result in death, particularly given poor access to adequate food. Improving quality and confidentiality within clinical service delivery, coupled with the introduction of food-supplement programmes should increase people's willingness to test and remain in care for HIV disease.

Social cognitive determinants of HIV voluntary counselling and testing uptake among married individuals in Dar es Salaam Tanzania: Theory of Planned Behaviour (TPB)

Background

Cumulative evidence indicates increasing HIV infection among married individuals. Voluntary Counselling and Testing for HIV (HCT) is known to be an effective intervention to induce safer sex behaviour and access to early treatment, care and support among married individuals, which are important for HIV prevention. In this context, knowledge of factors associated with HCT uptake among married individuals is critical in promoting the use of the services. This study therefore intended to identify the social cognitive factors associated with acceptance of HCT among married individuals.

Methods

In a cross-sectional analytical study face to face questionnaires were administered among 200 randomly selected married individuals in Kinondoni district, Dar es Salaam Tanzania. The questionnaire included self-reported HCT, socio-demographic variables and social cognitive variables (attitude, subjective norms, perceived control and perceived risk). Logistic regression was used to identify the independent association of social cognitive predictors of HCT among married individuals.

Results

Nearly half (42%) of the respondents had never had HCT. Of the social cognitive constructs, the strongest predictor of HCT uptake was attitude (OR per additional score point = 1.07, 95% CI 1.04-1.10) followed by perceived behavioural control (OR = 1.04, 95% CI 1.02-1.06). Subjective norm and perceived risk were not associated with HCT uptake.

Conclusion

Public health interventions targeting married individuals should be designed to enhance their positive attitude towards HCT and empower them to overcome barriers to the use of the services.

HIV testing service awareness and service uptake among female heads of household in rural Mozambique: results from a province-wide survey

Background

HIV voluntary counseling and testing (VCT) utilization remains low in many sub-Saharan African countries, particularly in remote rural settings. We sought to identify factors associated with service awareness and service uptake of VCT among female heads of household in rural Zambézia Province of north-central Mozambique which is characterized by high HIV prevalence (12.6%), poverty, and suboptimal health service access and utilization.

Methods

Our population-based survey of female heads of household was administered to a representative two-stage cluster sample using a sampling frame created for use on all national surveys and based on census results. The data served as a baseline measure for the Ogumaniha project initiated in 2009. Survey domains included poverty, health, education, income, HIV stigma, health service access, and empowerment. Descriptive statistics and logistic regression were used to describe service awareness and service uptake of VCT.

Results

Of 3708 women surveyed, 2546 (69%) were unaware of available VCT services. Among 1162 women who were aware of VCT, 673 (58%) reported no prior testing. In the VCT aware group, VCT awareness was associated with higher education (aOR = 2.88; 95% CI = 1.61, 5.16), higher income (aOR = 1.41, 95% CI = 1.06, 1.86), higher numeracy (aOR = 1.05, CI 1.03, 1.08), more children < age 5 in the home (aOR = 1.53; 95% CI = 1.07, 2.18), closer proximity to a health facility (aOR = 1.05; 95% CI = 1.03, 1.07), and mobile phone ownership (aOR = 1.37; 95% CI = 1.03, 1.84) (all p-values < 0.04). Having a higher HIV-associated stigma score was the factor most strongly associated with being less likely to test. (aOR = 0.41; 95% CI = 0.23, 0.71; p<0.001).

Conclusions

Most women were unaware of available VCT services. Even women who were aware of services were unlikely to have been tested. Expanded VCT and social marketing of VCT are needed in rural Mozambique with special attention to issues of community-level stigma reduction.

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.

Evidence-based programming for adolescent HIV prevention and care: operational research to inform best practices

BACKGROUND

Globally, a staggering number of adolescents, approximately 2.1 million, were estimated to be living with HIV in 2012. Unique developmental, psychosocial, and environmental considerations make them particularly vulnerable to HIV acquisition and argue for a comprehensive response to address this burgeoning problem.

METHODS

This article explores the current state of the science of HIV prevention, treatment, and care for adolescents and identifies opportunities to address knowledge gaps and improve health outcomes for this age group.

RESULTS

Over the past decade, several important milestones have been achieved in HIV prevention and care among adults, and despite evidence that adherence to care and medications among affected adolescents is significantly compromised, critical research among adolescents and young adults substantially lags behind. Operational research, in particular, is crucial to understanding how to use effective services and interventions for HIV prevention and care safely and effectively for adolescents who are in dire need.

CONCLUSIONS

Operational research among adolescent populations affected by HIV is critically needed to close the knowledge and investment gaps, and scale-up efforts for HIV prevention, treatment, care, and support for this vulnerable age group.

Perceptions about the acceptability and prevalence of HIV testing and factors influencing them in different communities in South Africa

HIV counselling and testing (HCT) is considered important because it is an entry point to a comprehensive continuum of care for HIV/AIDS. The South African Department of Health launched an HCT campaign in April 2010, and this reached 13,269,746 people by June 2011, of which 16% tested HIV positive and 400,000 of those were initiated into antiretroviral treatment. The overall objective of this project was to gain insight into the general perceptions about HIV testing in the different South African communities. Factors influencing testing in these communities were also explored. Discussions with twelve focus groups (FG) of 8-12 participants each were conducted with male and female participants recruited from both urban formal and informal communities in Cape Town and Durban. Participants included four racial groups represented by different age groups as follows: adolescents (12-17 years), youth (18-24 years) and adults (25 years and older). Data were analyzed using thematic coding. Among the key themes that emerged from the findings were the inaccurate perception of risk, fear of testing HIV positive, stigma and discrimination. Participants from both African and Indian FGs reported being less likely to do self-initiated HIV testing and counselling, while those from the FG consisting of young whites were more likely to learn about their HIV status through blood donations and campus HIV testing campaigns. Most FGs said they were likely to test if they understood the testing process better and also if the results are kept confidential. The present findings reiterate the importance of spreading positive messages and ensuring confidentiality for HIV testing in a society where there is still some stigma associated with people living with HIV/AIDS. This can partly be accomplished by the continuation of the national HCT campaign, which has been a considerable success in the fight against HIV/AIDS in South Africa during the past two years.

The centrality of laboratory services in the HIV treatment and prevention cascade: The need for effective linkages and referrals in resource-limited settings

Strong laboratory services and systems are critical for delivering timely and quality health services that are vital to reduce patient attrition in the HIV treatment and prevention cascade. However, challenges exist in ensuring effective laboratory health systems strengthening and linkages. In particular, linkages and referrals between laboratory testing and other services need to be considered in the context of an integrated health system that includes prevention, treatment, and strategic information. Key components of laboratory health systems that are essential for effective linkages include an adequate workforce, appropriate point-of-care (POC) technology, available financing, supply chain management systems, and quality systems improvement, including accreditation. In this review, we highlight weaknesses of and gaps between laboratory testing and other program services. We propose a model for strengthening these systems to ensure effective linkages of laboratory services for improved access and retention in care of HIV/AIDS patients, particularly in low- and middle-income countries.

The impact of voluntary counselling and testing services on sexual behaviour change and HIV incidence: observations from a cohort study in rural Tanzania

Background

It is widely assumed that voluntary counselling and testing (VCT) services contribute to HIV prevention by motivating clients to reduce sexual risk-taking. However, findings from sub-Saharan Africa have been mixed, particularly among HIV-negative persons. We explored associations between VCT use and changes in sexual risk behaviours and HIV incidence using data from a community HIV cohort study in northwest Tanzania.

Methods

Data on VCT use, sexual behaviour and HIV status were available from three HIV serological surveillance rounds undertaken in 2003–4 (Sero4), 2006–7 (Sero5) and 2010 (Sero6). We used multinomial logistic regression to assess changes in sexual risk behaviours between rounds, and Poisson regression to estimate HIV incidence.

Results

The analyses included 3,613 participants attending Sero4 and Sero5 (3,474 HIV-negative and 139 HIV-positive at earlier round) and 2,998 attending Sero5 and Sero6 (2,858 HIV-negative and 140 HIV-positive at earlier round). Among HIV-negative individuals VCT use was associated with reductions in the number of sexual partners in the last year (aRR Seros 4–5: 1.42, 95% CI 1.07-1.88; aRR Seros 5–6: 1.68, 95% CI 1.25-2.26) and in the likelihood of having a non-cohabiting partner in the last year (aRR Seros 4–5: 1.57, 95% CI 1.10-2.25; aRR Seros 5–6: 1.48, 95% CI 1.07-2.04) or a high-risk partner in the last year (aRR Seros 5–6 1.57, 95% CI 1.06-2.31). However, VCT was also associated with stopping using condoms with non-cohabiting partners between Seros 4–5 (aRR 4.88, 95% CI 1.39-17.16). There were no statistically significant associations between VCT use and changes in HIV incidence, nor changes in sexual behaviour among HIV-positive individuals, possibly due to small sample sizes.

Conclusions

We found moderate associations between VCT use and reductions in some sexual risk behaviours among HIV-negative participants, but no impacts among HIV-positive individuals in the context of low overall VCT uptake. Furthermore, there were no significant changes in HIV incidence associated with VCT use, although declining background incidence and small sample sizes may have prevented us from detecting this. The impact of VCT services will ultimately depend upon rates of uptake, with further research required to better understand processes of behaviour change following VCT use.

Heterogeneous HIV testing preferences in an urban setting in Tanzania: results from a discrete choice experiment

BACKGROUND

Efforts to reduce Human Immunodeficiency Virus (HIV) transmission through treatment rely on HIV testing programs that are acceptable to broad populations. Yet, testing preferences among diverse at-risk populations in Sub-Saharan Africa are poorly understood. We fielded a population-based discrete choice experiment (DCE) to evaluate factors that influence HIV-testing preferences in a low-resource setting.

METHODS

Using formative work, a pilot study, and pretesting, we developed a DCE survey with five attributes: distance to testing, confidentiality, testing days (weekday vs. weekend), method for obtaining the sample for testing (blood from finger or arm, oral swab), and availability of HIV medications at the testing site. Cluster-randomization and Expanded Programme on Immunization (EPI) sampling methodology were used to enroll 486 community members, ages 18-49, in an urban setting in Northern Tanzania. Interviewer-assisted DCEs, presented to participants on iPads, were administered between September 2012 and February 2013.

RESULTS

Nearly three of five males (58%) and 85% of females had previously tested for HIV; 20% of males and 37% of females had tested within the past year. In gender-specific mixed logit analyses, distance to testing was the most important attribute to respondents, followed by confidentiality and the method for obtaining the sample for the HIV test. Both unconditional assessments of preferences for each attribute and mixed logit analyses of DCE choice patterns suggest significant preference heterogeneity among participants. Preferences differed between males and females, between those who had previously tested for HIV and those who had never tested, and between those who tested in the past year and those who tested more than a year ago.

CONCLUSION

The findings suggest potentially significant benefits from tailoring HIV testing interventions to match the preferences of specific populations, including males and females and those who have never tested for HIV.

Understanding the relationships among HIV/AIDS-related stigma, health service utilization, and HIV prevalence and incidence in Sub-Saharan Africa: a multi-level theoretical perspective

HIV-positive individuals often face community-wide discrimination or public shame and humiliation as a result of their HIV-status. In Sub-Saharan Africa, high HIV incidence coupled with unique cultural contexts make HIV-positive individuals particularly likely to experience this kind of HIV/AIDS-related (HAR) stigma. To date, there is a relatively small amount of high-quality empirical literature specific to HAR stigma in this context, supporting the notion that a better understanding of this phenomenon is needed to inform potential interventions. This paper provides a thorough review of the literature specific to HAR stigma in Sub-Saharan Africa, finding (a) qualitative support for the existence of important relationships between HAR stigma and health service utilization and barriers; (b) a need for more quantitative study of stigma and its relationships both to health service utilization and to HIV outcomes directly; and (c) a disconnect between methodological techniques used in this context-specific literature and well-known theories about stigma as a general phenomenon. This paper then draws from its empirical literature review, as well as from well-known theoretical frameworks from multiple disciplines, to propose a theoretical framework for the ecological and multilevel relationships among HAR stigma, health service utilization, and HIV outcomes in this context.

Importance of relationship context in HIV transmission: results from a qualitative case-control study in Rakai, Uganda

We present results from life history interviews with 60 young adults from southern Uganda. Using a novel qualitative case-control design, we compared newly HIV-positive cases with HIV-negative controls matched on age, gender, marital status, and place of residence. Relationship context was the most salient theme differentiating cases from controls. Compared with HIV-negative respondents, recent seroconverters described relationships marked by poorer communication, greater suspicion and mistrust, and larger and more transitory sexual networks. Results highlight the importance of dyadic approaches to HIV and possibly of couple-based interventions. Using HIV-matched pairs allowed additional understanding of the factors influencing transmission. This hybrid methodological approach holds promise for future studies of sexual health.

HIV testing: current practice and future directions

New approaches to expanding HIV testing and effective treatment and the wider availability of rapid testing technology have created new opportunities for achieving national and global HIV testing goals. In spite of HIV testing expansion in many settings, growing evidence of the prevention benefits of HIV testing, and the development of new, cost-effective approaches to HIV testing service provision, formidable obstacles to HIV testing expansion persist. Inequitable testing coverage exists within and across countries. While the proportion of people with HIV aware of their status is about 80% in the U.S., the majority of HIV-infected persons in Africa are unaware of their status. Testing of most-at-risk populations, couples, children, and adolescents pose still unresolved policy and programmatic challenges. Future directions for HIV testing include rapid testing technology and detection of acute HIV infection, self-testing expansion, and partner notification. Expanded routine HIV screening and widespread testing is a public health imperative to reach national and international HIV prevention and treatment goals.

Community stigma endorsement and voluntary counseling and testing behavior and attitudes among female heads of household in Zambézia Province, Mozambique

Background

Some aspects of HIV-related stigma have been shown to be a barrier to HIV services uptake and adherence to antiretroviral treatment (ART). Distinguishing which domains of stigma impact HIV services uptake can enhance the efficacy and efficiency of stigma-reduction interventions.

Methods

The relationships between use of voluntary counseling and testing (VCT) services and two domains of community stigma identified through factor analysis, negative labeling/devaluation and social exclusion, were investigated among 3749 female heads of household. Data were from a general household survey conducted in rural Mozambique. Multivariable logistic regression outcomes were: lifetime VCT use, past-6-months VCT use and VCT endorsement.

Results

Thirteen percent (13%) of the participants reported lifetime VCT use, 10% reported past-6-months VCT use and 63% endorsed VCT. A 25-point decrease (from 50 to 25) in the score for negative labeling and devaluation stigma was associated with increased lifetime VCT use (adjusted OR: 1.6, 95% CI: 1.1-2.3) and past-6-months VCT use (adjusted OR: 1.6, 95% CI: 1.1-2.4). A decrease from 50 to 25-points in the score for social exclusion stigma was associated with 1.5 and 1.3-fold increase in odds for past-6-months VCT use and endorsing VCT use, respectively (p < 0.001 for both). Compared with never-testers, considerably high endorsement of VCT use was observed among testers who did not receive HIV test results (adjusted OR: 2.7, 95% CI: 1.6-4.6) and much higher among testers who received results (adjusted OR: 7.3, 95% CI: 4.9-11.0). Distance from health facilities was associated with lower VCT use, but not lower endorsement of VCT.

Conclusions

VCT use and endorsement might differ by domains of stigma held by individuals in the community. Greater uptake and favorable disposition towards use of VCT services in rural settings might be achieved by addressing stigma via domain-specific interventions and by improving the proximity of services and the dissemination of HIV test results.
