Repeat Voluntary HIV Counseling and Testing (VCT), Sexual Risk Behavior and HIV Incidence in Rakai,Uganda

We examined the effects of repeat Voluntary HIV counseling and testing (VCT) on sexual risk behaviors and HIV incidence in 6,377 initially HIV-negative subjects enrolled in a prospective STD control for HIV prevention trial in rural Rakai district, southwestern Uganda. Sixty-four percent accepted VCT, and of these, 62.2% were first time acceptors while 37.8% were repeat acceptors. Consistent condom use was 5.8% in repeat acceptors, 6.1% in first time acceptors and 5.1% in non-acceptors. A higher proportion of repeat acceptors (15.9%) reported inconsistent condom use compared to first-time acceptors (12%) and non-acceptors (11.7%). Also, a higher proportion of repeat acceptors (18.1%) reported 2+ sexual partners compared to first-time acceptors (14.1%) and non-acceptors (15%). HIV incidence rates were 1.4/100 py (person-years) in repeat acceptors, 1.6/100 py in first time acceptors and 1.6/100 py in non-acceptors. These data suggest a need for intensive risk-reduction counseling interventions targeting HIV-negative repeat VCT acceptors as a special risk group.     

Patterns of Self-reported Behaviour Change Associated with Receiving Voluntary Counselling and Testing in a Longitudinal Study from Manicaland, Zimbabwe

Voluntary counselling and testing (VCT) is promoted as a potential HIV prevention measure. We describe trends in uptake of VCT for HIV, and patterns of subsequent behaviour change associated with receiving VCT in a population-based open cohort in Manicaland, Zimbabwe. The relationship between receipt of VCT and subsequent reported behaviour was analysed using generalized linear models with random effects. At the third survey, 8.6% of participants (1,079/12,533), had previously received VCT. Women who received VCT, both those positive and negative, reduced their reported number of new partners. Among those testing positive, this risk reduction was enhanced with time since testing. Among men, no behavioural risk reduction associated with VCT was observed. Significant increases in consistent condom use, with regular or non-regular partners, following VCT, were not observed. This study suggests that, among women, particularly those who are infected, behavioural risk reduction does occur following VCT.     

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

OBJECTIVES: To examine the determinants of uptake of voluntary counselling and testing (VCT) services, to assess changes in sexual risk behaviour following VCT, and to compare HIV incidence amongst testers and non-testers. METHODS: Prospective population-based cohort study of adult men and women in the Manicaland province of eastern Zimbabwe. Demographic, socioeconomic, sexual behaviour and VCT utilization data were collected at baseline (1998-2000) and follow-up (3 years later). HIV status was determined by HIV-1 antibody detection. In addition to services provided by the government and non-governmental organizations, a mobile VCT clinic was available at study sites. RESULTS: Lifetime uptake of VCT increased from under 6% to 11% at follow-up. Age, increasing education and knowledge of HIV were associated with VCT uptake. Women who took a test were more likely to be HIV positive and to have greater HIV knowledge and fewer total lifetime partners. After controlling for demographic characteristics, sexual behaviour was not independently associated with VCT uptake. Women who tested positive reported increased consistent condom use in their regular partnerships. However, individuals who tested negative were more likely to adopt more risky behaviours in terms of numbers of partnerships in the last month, the last year and in concurrent partnerships. HIV incidence during follow-up did not differ between testers and non-testers. CONCLUSION: Motivation for VCT uptake was driven by knowledge and education rather than sexual risk. Increased sexual risk following receipt of a negative result may be a serious unintended consequence of VCT. It should be minimized with appropriate pre- and post-test counselling.     

Voluntary HIV counseling and testing acceptance, sexual risk behavior and HIV incidence in Rakai, Uganda

OBJECTIVE: To assess the acceptance of voluntary HIV counseling and testing (VCT) and the effects of VCT on sexual risk behavior and HIV acquisition in Rakai, Uganda. METHODS: In a rural cohort, 10 694 consenting adults were interviewed, provided blood for HIV testing and were offered free VCT by community resident counselors. The proportions receiving VCT and the adjusted risk ratio (adj. RR) of VCT acceptance were estimated by log binomial regression. Risk behaviors and HIV incidence per 100 person-years (PY) in HIV-negative acceptors and non-acceptors of VCT were assessed prospectively. RESULTS: Although 93% initially requested HIV results, 62.2% subsequently accepted VCT. VCT acceptance was lower among persons with no prior VCT [Adj. RR = 0.88; 95% confidence interval (CI), 0.85-0.90], individuals with primary education (adj. RR = 0.94; 95% CI, 0.90-0.99) or higher (adj. RR = 0.91; 95% CI, 0.87-0.97), individuals who were HIV-positive (adj. RR = 0.72; 95% CI, 0.68-0.76), and persons reporting condom use in the past 6 months (inconsistent users, adj. RR = 0.95; 95% CI, 0.90-0.99; consistent users, adj. RR = 0.88; 95% CI, 0.82-0.95). VCT acceptance was higher among the currently married (adj. RR = 1.14; 95% CI, 1.08-1.20) and previously married (adj. RR = 1.11; 95% CI, 1.04-1.18). Receipt of results was not significantly associated with age, gender, and self-perception of HIV risk. There were no significant differences in sexual risk behaviors, or in HIV incidence between acceptors (1.6/100 PY) and non-acceptors (1.4/100 PY) of VCT. CONCLUSION: In this rural cohort where VCT services are free and accessible, there is self-selection of individuals accepting VCT, and no impact of VCT on subsequent risk behaviors or HIV incidence.     

Voluntary counselling,HIV testing and adjunctive cotrimoxazole reduces mortality in tuberculosis patients in Thyolo,Malawi

OBJECTIVES: To assess the feasibility and effectiveness of voluntary counselling, HIV testing and adjunctive cotrimoxazole in reducing mortality in a cohort of tuberculosis (TB) patients registered under routine programme conditions in a rural district of Malawi. DESIGN: 'Before' and 'after' cohort study using historical controls. METHODS: Between 1 July 1999 and 30 June 2000 all TB patients were started on standardized anti-TB treatment, and offered voluntary counselling and HIV testing (VCT). Those found to be HIV-positive were offered cotrimoxazole at a dose of 480 mg twice daily, provided there were no contraindications. Side-effects were monitored clinically. End-of-treatment outcomes in this cohort (intervention group) were compared with a cohort registered between 1 July 1998 and 30 June 1999 in whom VCT and cotrimoxazole was not offered (control group). FINDINGS: A total of 1986 patients was registered in the study: 1061 in the intervention group and 925 in the control cohort. In the intervention group, 1019 (96%) patients were counselled pre-test, 964 (91%) underwent HIV testing and 938 (88%) were counselled post-test. The overall HIV-seroprevalence rate was 77%. A total of 693 patients were given cotrimoxazole of whom 14 (2%) manifested minor dermatological reactions. The adjusted relative risk of death in the intervention group compared with the control group was 0.81 (P < 0.001). The number needed to treat with VCT and adjunctive cotrimoxazole to prevent one death during anti-TB treatment was 12.5. INTERPRETATION: This study shows that VCT and adjunctive cotrimoxazole is feasible, safe and reduces mortality rates in TB patients under routine programme conditions.     

Uptake of HIV voluntary counselling and testing services in rural Tanzania: implications for effective HIV prevention and equitable access to treatment

Objective To describe the associations between socio‐demographic, behavioural and clinical characteristics and the use of HIV voluntary counselling and testing (VCT) services among residents in a rural ward in Tanzania. Methods Eight thousand nine hundred and seventy participants from a community‐based cohort were interviewed, provided blood for research HIV testing, and were offered VCT. Univariate and multivariate logistic regression was used to identify socio‐demographic, clinical and behavioural factors associated with VCT use. Results Although 31% (1246/3980) of men and 24% (1195/4990) of women expressed an interest in the service, only 12% of men and 7% of women subsequently completed VCT. Socio‐demographic factors, such as marital status, area of residence, religion and ethnicity influenced VCT completion among males and females in different ways, while self‐perceived risk of HIV, prior knowledge of VCT, and sex with a high‐risk partner emerged as important predictors of VCT completion among both sexes. Among males only, those infected with HIV for 5 years or less tended to self‐select for VCT compared to HIV‐negatives (adjusted odds ratio = 1.43; 95% CI: 0.99–2.14). This contributed to a higher proportion of HIV‐positive males knowing their status compared to HIV‐positive females. Conclusions In this setting, a disproportionate number of HIV‐positive women are failing to learn their status, which has implications for equitable access to onward referral for care and treatment services. Evidence that some high‐risk behaviours may prompt VCT use is encouraging, although further interventions are required to improve knowledge about HIV risk and the benefits of VCT. Targeted interventions are also needed to promote VCT uptake among married women and rural residents.     

Trends in the uptake of voluntary counselling and testing for HIV in rural Tanzania in the context of the scale up of antiretroviral therapy

Objectives To describe trends in voluntary counselling and testing (VCT) use and to assess whether high‐risk and infected individuals are receiving counselling and learning their HIV status in rural Tanzania. Methods During two rounds of linked serological surveys (2003–2004 and 2006–2007) with anonymous HIV testing among adults, VCT was offered to all participants. The crude and adjusted odds ratios for completing VCT in each survey were calculated to compare uptake by demographic, behavioural and clinical characteristics, stratified by sex. Repeat testing patterns were also investigated. Results The proportion of participants completing VCT increased from 10% in 2003–2004 to 17% in 2006–2007, and among HIV‐infected persons from 14% to 25%. A higher proportion of men than women completed VCT in both rounds, but the difference declined over time. Socio‐demographic and behavioural factors associated with VCT completion were similar across rounds, including higher adjusted odds of VCT with increasing numbers of sexual partners in the past 12 months. The proportion having ever‐completed VCT reached 26% among 2006–2007 attendees, with repeat testing rates highest among those aged 35–44 years. Among 3923 participants attending both rounds, VCT completion in 2006–2007 was 17% among 3702 who were HIV negative in both rounds, 19% among 124 who were HIV infected in both rounds and 22% among 96 who seroconverted between rounds. Conclusion VCT services are attracting HIV‐infected and high‐risk individuals. However, 2 years after the introduction of antiretroviral therapy, the overall uptake remains low. Intensive mobilisation efforts are needed to achieve regular and universal VCT use.     

Decline in sexually transmitted infection prevalence and HIV incidence in female barworkers attending prevention and care services in Mbeya Region, Tanzania

OBJECTIVE: To assess trends in sexually transmitted infection (STI) prevalence and HIV incidence and associated factors in a cohort of female barworkers exposed to behavioural interventions and STI screening and treatment. METHODS: An open cohort of 600 female barworkers in Mbeya Region, Tanzania was offered 3-monthly information and education sessions on HIV/STI and reproductive health, voluntary HIV counselling and testing and clinical health check-ups including STI syndromic management with simple STI laboratory support. Outcome assessments included HIV, herpes simplex virus type 2 (HSV-2) and syphilis serology, polymerase chain reaction for Neisseria gonorrhoeae, Chlamydia trachomatis and ulcerative STI, microscopy for Trichomonas vaginalis, Candida albicans and bacterial vaginosis and interviews on sociodemographic and behavioural characteristics. RESULTS: Over a period of 30 months 600 barworkers were enrolled at the baseline examination round and 153 thereafter as replacements for losses to follow-up. At 3-monthly examinations the prevalence of gonorrhoea declined steadily from 22.2 to 6.8% (odds ratio for trend per quarter: 0.81; P < 0.001). The prevalence of all other STI/RTI, except for genital herpes and bacterial vaginosis, also decreased significantly. HIV incidence declined from 13.9/100 to 5.0/100 person-years over three consecutive 9-month periods. HIV incidence was significantly associated with genital ulcers and positive syphilis serology, but not with genital herpes or HSV-2 seropositivity. CONCLUSION: A relatively simple intervention consisting of regular 3-monthly STI screening and syndromic management in combination with HIV/STI information and counselling sessions was well accepted and effective in reducing STI among barworkers. Such interventions should be implemented more widely in high-risk environments in sub-Saharan Africa.     

HIV infection and silicosis: the impact of two potent risk factors on the incidence of mycobacterial disease in South African miners

OBJECTIVE: To investigate the combined effects of HIV infection and silicosis on mycobacterial disease. DESIGN AND SETTING: A retrospective cohort of 1374 HIV-positive and 2648 HIV-negative miners who attended a South African gold mining hospital and primary health clinics. PARTICIPANTS: Miners who had been tested for HIV, with consent, at primary health clinics during 1991-1996, predominantly because of a symptomatic sexually transmitted disease. RESULTS: Tuberculosis (TB) incidence was 4.9 and 1.1 per 100 person-years in HIV-positive and HIV-negative miners respectively. The incidence of Mycobacterium kansasii disease was also high (0.32 and 0.10 per 100 person-years, respectively). Silicosis was highly prevalent, implying inadequate dust control, and was a significant TB risk factor among both HIV-positive and HIV-negative men (adjusted incidence rate ratios 1.4-2.5 according to radiological severity). The data were consistent with the risks of silicosis and HIV combining multiplicatively, but did not fit an additive model. The incidence of HIV-associated TB increased significantly during the study, with no corresponding change in HIV-negative rates, to reach 16.1 per 100 person-years among HIV-positive silicotics. CONCLUSIONS: The risks of silicosis and HIV infection combine multiplicatively, so that TB remains as much a silica-related occupational disease in HIV-positive as in HIV-negative miners, and HIV-positive silicotics have considerably higher TB incidence rates than those reported from other HIV-positive Africans. The increasing impact of HIV over time may indicate epidemic TB transmission with rapid disease development in HIV-infected miners. Similar but currently unrecognized interactions may be contributing to TB control problems in other industrializing countries affected by the HIV epidemic.     

Condom use after voluntary counselling and testing in central Mozambique

OBJECTIVE: To evaluate the efficacy of voluntary counselling and testing (VCT) for HIV/AIDS in changing risky sexual behaviour in central Mozambique. METHOD: Longitudinal cohort study of men and women aged at least 18 years from October 2002 to June 2003. We interviewed 622 participants in VCT groups and 598 in non-VCT groups. The interviews occurred before counselling and 4 and 6 months afterwards. RESULTS: Reported use of condoms while having sex with a friends/prostitute increased over each time period in the VCT group and between baseline and first visit in the non-VCT group. Both men and women in the VCT group increased their condom use over time, but the women in the non-VCT group did not. Reported always/sometimes use of condoms for both literate and illiterate subjects was higher and rose over time in the VCT group. CONCLUSION: People who undergo voluntary counselling and testing fro HIV/AIDS change their behaviour, presumably as a result of their counselling.     

The use of a monitoring tool to assess counselling and HIV testing in the public health sector in Malawi

Scaling up of counselling and HIV testing (VCT) services requires a system of regular monitoring and evaluation. AVCT monitoring tool was developed through a consultative process and used to assess counselling and HIV testing services in 16 government and mission hospitals in Malawi, which had started expanded HIV-TB activities in July 2003. The essential components of theVCT monitoring tool included assessments of: (i) the hospital VCT personnel, in particular the number of counsellors (full-time and part-time) and those trained in and performing whole blood rapid HIV testing; (ii) the hospital laboratory service, in particular the protocols for HIV testing; (iii) the number, structure and function of dedicated VCT rooms; (iv) registers for patients, clients and donors having HIV tests; and (v) the quality of VCT through structured interviews with HIV-positive patients with TB. The main findings were: 9644 patients and clients were HIV tested between July and September 2003; HIV testing protocols were not standardized and differed between hospitals; there was little in the way of external quality assurance and there were deficiencies in the counselling process. In each hospital, the mean time taken to obtain the data and complete theVCT monitoring tool was 3 h. TheVCT monitoring tool is straightforward to use, and the data collected should help to improve standardization, quality and future planning of VCT services in the country.     

Syndromic treatment of sexually transmitted diseases reduces the proportion of incident HIV infections attributable to these diseases in rural Tanzania

OBJECTIVES: To compare the proportion of HIV seroconversions attributable to other sexually transmitted diseases in the intervention and comparison arms of the Mwanza sexually transmitted diseases (STD) intervention trial. DESIGN: Case-control study of 96 cases of HIV seroconversion and 974 HIV-negative controls, nested within the Mwanza trial cohort. METHODS: Data on reported STD symptoms during 2 years of follow-up, and serological evidence of recent syphilis, were used to obtain odds ratios (ORs) for HIV seroconversion, adjusted for community, age, marital status, sex partners and travel. Population-attributable fractions (PAF) of HIV seroconversions associated with these STD exposures were calculated separately for the intervention and comparison arms, and for men and women. RESULTS: In men in the comparison arm, adjusted ORs for ulcers (14.8), discharge (3.3), any symptom (4.1) and any STD (4.0) were highly significant. There were no significant associations between HIV incidence and STD exposures in the intervention arm. The PAF were consistently higher in the comparison arm than the intervention arm. In men, the PAF for any STD was 39.6% [95% confidence interval (CI), 12.4-58.3)] in the comparison arm but only 12.0% (CI, 0.0-35.9) in the intervention arm. The PAF for women were lower than for men. CONCLUSIONS: These are minimal PAF estimates and they do not account for STD effects on HIV infectiousness. Nevertheless, a substantial proportion of new HIV infections in men in the comparison arm were attributable to STD. Lower PAF in the intervention arm than in the comparison arm for men provide further evidence of the role of STD cofactors in HIV transmission, supporting the hypothesis that the Mwanza intervention reduced the duration of symptomatic STD, thus reducing the HIV risk associated with such STD.     

HIV incidence and risk behaviours after voluntary HIV counselling and testing (VCT) among adults aged 19-35 years living in peri-urban communities around Chiang Mai city in northern Thailand, 1999

The Thai government began HIV voluntary counselling and testing (VCT) in all provinces in 1992. We evaluated HIV incidence after participants utilized VCT and its effect on risk behaviours among northern Thai adults aged 19-35 years. A total of 924 men and 1,327 women volunteered to participate in the study. Subjects were counseled, interviewed (socio-demographic, HIV risk behaviour, and HIV testing history), and tested for HIV infection at baseline and at 6 months follow-up. All participants were provided group pre-test counselling; HIV test results were provided in individual confidential post-test counselling. Overall, 329 of 391 men and 621 of 669 women who reported a prior HIV test before participating in our study reported negative results at the previous test. Of these, nine men and 13 women tested positive at baseline, giving incidence rates of 1.04 and 0.69 per 100 person years (PY), respectively. Recent risk behaviour was rare; as a result, the effects of VCT on risk behaviours among the study participants could not be determined. The HIV incidence after VCT among this study population is substantial. Studies to investigate factors associated with HIV incidence among VCT clients could provide insights for more effective HIV prevention.     

Cost effectiveness of couple counselling to enhance infant HIV-1 prevention

Data collected in the years 2001--2003 from an antenatal clinic in Nairobi, Kenya, were used to assess the benefit of couple counselling and test it as a way of increasing the uptake of interventions in the prevention of mother-to-child transmission of HIV-1. Among 2833 women enrolled, 311 (11%) received couple pretest counselling and 2100 (74%) accepted HIV-1 testing. Among those tested 314 (15%) were HIV-1 seropositive. We incorporated these and other data from the cohort study into a spreadsheet-based model and costs associated with couple counselling were compared with individual counselling in a theoretical cohort of 10,000 women. Voluntary couple counselling and testing (VCT), although more expensive, averted a greater number of infant infections when compared with individual VCT. Cost per disability-adjusted life year was similar to that of individual VCT. Sensitivity analyses found that couple VCT was more cost-effective in scenarios with increased uptake of couple counselling and higher HIV-1 prevalence.     

A cluster randomized-controlled trial to determine the effectiveness of Stepping Stones in preventing HIV infections and promoting safer sexual behaviour amongst youth in the rural Eastern Cape, South Africa: trial design, methods and baseline findings

OBJECTIVE: To describe the study design, methods and baseline findings of a behavioural intervention trial aimed at reducing HIV incidence. METHOD: A cluster randomized-controlled trial (RCT) conducted in 70 villages in rural South Africa. A behavioural intervention, Stepping Stones, was implemented in 35 communities in two workshops of 20 men and 20 women in each community who met for 17 sessions (50 h) over a period of 3-12 weeks. Individuals in the control arm communities attended a single session of about 3 h on HIV and safer sex. Impact assessment was conducted through two questionnaire and serological surveys at 12-month intervals. The primary outcome was HIV incidence and secondary measures included changes in knowledge, attitude and sexual behaviours. Qualitative research was also undertaken with 10 men and 10 women from two sites receiving the intervention (one rural and one urban) and five men and five women from one village in the control arm. They were interviewed individually three times prior to the workshops and then 9-12 months later. RESULTS: A total of 2776 participants (1409 intervention and 1367 control) were enrolled at baseline and had an interview, and HIV sero-status was established. HIV baseline prevalence rates in women were 9.8% in the intervention arm and 12.8% in the control arm. In men the prevalence was 1.7% in the intervention arm and 2.1% in the control arm. Demographic and behavioural characteristics were similar in the two arms. In the intervention groups 59.9% of participants attended more than 75% of the sessions. In the control group 66.3% attended the control session. CONCLUSION: This is the third RCT to be conducted in sub-Saharan Africa evaluating a behavioural intervention using HIV incidence as a primary outcome. It is of particular interest as the intervention in question is used in many developing countries. There is good baseline comparability between the study arms and the process data on the workshops suggested that the interventions were feasible and adequately implemented.     

Voluntary counselling, HIV testing and adjunctive cotrimoxazole are associated with improved TB treatment outcomes under routine conditions in Thyolo District, Malawi.

SETTING: Two rural districts in Malawi: Thyolo, where voluntary counselling and human immunodeficiency virus (HIV) testing (VCT) is offered to all tuberculosis (TB) patients and adjunctive cotrimoxazole to HIV positives, and Mulanje, where no such interventions are offered. OBJECTIVES: For all TB patients registered in 2001: 1) to determine the uptake of VCT and cotrimoxazole in Thyolo, and 2) to compare treatment outcomes between Thyolo and Mulanje. DESIGN: A cohort study using routinely collected programme data. RESULTS: There were 1239 TB patients in Mulanje and 1103 in Thyolo. In Thylo, 1064 (97%) patients consented to VCT, 1006 were HIV tested (91%) and 761 (69%) were started on cotrimoxazole a median of 4 days from registration; 77% of patients tested in Thyolo were HIV-positive. For all TB patients, in Thyolo and Mulanje, treatment success was respectively 75% and 61% (P < 0.001); death was 21% and 25% (P = 0.026); and other outcomes were 4% and 14% (P < 0.001). The adjusted relative risks of treatment success (1.23), death (0.84) and other outcomes (0.26) in Thyolo were significantly different from those in Mulanje (P < 0.001). CONCLUSION: VCT and adjunctive cotrimoxazole is well accepted by TB patients in Thyolo and, with other HIV care and support services, is associated with good treatment outcome indicators for the National Tuberculosis Programme. This intervention is being expanded to other districts in Malawi, and other African countries should consider a similar approach to the dual HIV-TB epidemic.     

Attitudes to HIV voluntary counselling and testing among mineworkers in South Africa: will availability of antiretroviral therapy encourage testing?

We conducted a study to identify attitudes that influence uptake of HIV voluntary counselling and testing (VCT) amongst gold mine workers in South Africa; 105 healthy men were interviewed. The level of basic knowledge of HIV was high, but reported awareness of the extent of HIV infection in the workforce and perceived personal risk of HIV infection was low. Health issues were considered the most important indication for HIV testing and one-third had been tested. Fear of testing positive for HIV and the potential consequences, particularly stigmatization, disease and death, were the major identified barriers to VCT. Half of the participants felt workplace education programmes needed to be improved to promote VCT access. Twenty-six per cent became more favourably inclined towards HIV testing in response to information on improvements that have been made to the confidentiality and convenience of the company's VCT service. Only 14% then indicated that they would be more likely to access VCT if antiretroviral therapy became available. A vigorous community education programme is essential if the introduction of ART is to be effective in promoting uptake of VCT.     

A peer-education intervention to reduce injection risk behaviors for HIV and hepatitis C virus infection in young injection drug users

OBJECTIVES: To evaluate whether a behavioral intervention, which taught peer education skills, could reduce injection and sexual risk behaviors associated with primary HIV and hepatitis C virus infection (HCV) among young injection drug users (IDU). DESIGN: We conducted a randomized controlled trial involving HIV and HCV antibody-negative IDU, aged 15-30 years, recruited in five United States cities. A six-session, small-group, cognitive behavioral, skills-building intervention in which participants were taught peer education skills (n = 431) was compared with a time-equivalent attention control (n = 423). Baseline visits included interviews for sociodemographic, psychosocial, and behavioral factors during the previous 3 months; HIV and HCV antibody testing; and pre/posttest counselling. Procedures were repeated 3 and 6 months postintervention. RESULTS: The intervention produced a 29% greater decline in overall injection risk 6 months postintervention relative to the control [proportional odds ratio 0.71; 95% confidence limit (CL) 0.52, 0.97], and a 76% decrease compared with baseline. Decreases were also observed for sexual risk behaviors, but they did not differ by trial arm. Overall HCV infection incidence (18.4/100 person-years) did not differ significantly across trial arms (relative risk 1.15; 95% CL 0.72, 1.82). No HIV seroconversions were observed. CONCLUSION: Interventions providing information, enhancing risk-reduction skills, and motivating behavior change through peer education training can reduce injection risk behaviors, although risk elimination might be necessary to prevent HCV transmission.     

HIV voluntary counselling and testing in Nakuru, Kenya: findings from a community survey

OBJECTIVES: HIV voluntary counselling and testing (VCT) is important for prevention, detection and treatment of HIV infection. A study was conducted to determine the extent of utilization of VCT, and to study the attitudes and preferences of the community regarding VCT. METHODS: A total of 301 adults, aged 18-49 years, residing in Nakuru, Kenya were randomly selected using a two-stage sampling process. A self-administered questionnaire delivered during home visits was used to collect data over a 4-week period. RESULTS: The majority of study participants (184 of 287; 64.1%) had never been tested for HIV; 77 (26.8%) had received VCT, and 26 (9.1%) had received HIV testing without counselling. A total of 219 (78.2%) of the 280 responding participants expressed readiness to have VCT. The majority of participants (216 of 296; 73%) preferred VCT, while 46 (15.5%) preferred testing without counselling. The majority (227; 76.7%) preferred couple testing and dedicated clinics and private doctors' offices as testing facilities. The choice of a nearby facility was ranked above the provision of anonymity by most participants (162 of 298; 54.4%; vice versa for 136 of 298; 45.6%). CONCLUSIONS: With HIV/AIDS continuing to be a major public health concern in Kenya, the issues surrounding acceptance and use of VCT need to be addressed. Enhancing community awareness of the benefits of early HIV diagnosis, providing couple-based VCT as an integral part of VCT and increasing access to VCT testing sites may enhance utilization of VCT.     

Use of UNAIDS tools to evaluate HIV voluntary counselling and testing services for mineworkers in South Africa

HIV voluntary counselling and testing (VCT) is now an integral part of many HIV care and control programmes. However, very little work has been done to assess the quality of VCT services. An evaluation of VCT services for mineworkers in Welkom, South Africa was conducted to assess client and counsellor satisfaction, the quality of the services and to identify barriers to uptake of VCT. A cross-sectional survey was carried out using tools developed by UNAIDS, consisting of semi-structured interviews and observation of counselling sessions. Twenty-two nurse counsellors and six community volunteers were interviewed. Twenty-four counselling sessions were observed and 24 client exit interviews were conducted. Although nine of the 22 nurse counsellors had only in-service rather than formal training for HIV counselling whereas all community volunteers had been formally trained, nurse counsellors demonstrated better interpersonal skills than did community volunteers. Both clients and counsellors identified fear of a positive result as a major barrier to HIV testing. Clients also raised concerns about confidentiality. UNAIDS evaluation tools were a feasible and an acceptable method of assessing VCT in this operational setting. The study identified areas where training needs to be strengthened and suggested ways of improving the services, and changes to the service have now been implemented in line with these recommendations.
