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.  相似文献

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.  相似文献

This paper examines the socio-demographic factors and sexual risk behaviors (condom use, number of sexual partners, STI symptoms) associated with voluntary counselling and testing (VCT) acceptance and self-perceived risk of being HIV-infected among black men with multiple and younger sex partners in a South African township outside of Cape Town. Using respondent driven sampling, we interviewed 421 men, of whom 409 (97.3%) consented to provide a dried blood spot, 12.3% were HIVinfected (95% confidence intervals [CI.] 8.3, 16.9) and 47.2% (CI. 41.1, 53.6) accepted on site VCT. Twenty six percent (CI. 20.2, 30.7) reported having an HIV test in the past year. Few men perceived themselves as very likely to be infected with HIV (15.6%; CI. 10.4, 20.5). VCT acceptance was significantly associated with being older, married or living with a partner, having higher education, having four to six partners in the past three months and testing HIV positive. Self-perceived likelihood of being HIV infected was significantly associated with low condom use and having seven or more partners in the past three months, and testing HIV positive. These findings indicate that men correctly understand that engaging in certain HIV risk behaviors increases the likelihood of HIV-infection. However, those who perceive themselves at high risk of having HIV do not seek testing. Further investigation into the psychological and cultural barriers to reducing risky sexual behaviors and accessing VCT and other HIV services is recommended.  相似文献

OBJECTIVES: Voluntary counseling and testing (VCT) for the human immunodeficiency virus (HIV) is recommended for persons treated for tuberculosis (TB). Opportunities to diagnose HIV may be missed by limiting HIV testing to only persons diagnosed with TB. Among TB suspects in Uganda, we determined HIV prevalence, risk behaviors, and willingness to refer family for VCT. METHODS: Consenting adult patients presenting for evaluation at a referral TB clinic received same-day VCT. TB diagnosis data were abstracted from clinical records. RESULTS: Among 665 eligible patients, 565 (85%) consented to VCT. Among these, 238 (42%) were HIV-positive. Of the HIV-infected patients, 37% had received a non-TB diagnosis. HIV seroprevalence was higher in patients with a non-TB diagnosis (49%) than those diagnosed with TB (39%) (P = 0.02). Fewer than 6% of HIV-infected patients reported always using condoms with sexual partners. The majority of patients (86%) reported being 'very willing' to refer family members for VCT. CONCLUSIONS: Over 35% of HIV-infected cases in our population would have been undetected if HIV testing was limited to cases with diagnosed TB. The high HIV seroprevalence in both TB and non-TB cases merits HIV testing for all patients evaluated at TB clinics. HIV-infected TB suspects reporting high-risk behavior are at risk for HIV transmission, and should receive risk-reduction counseling.  相似文献

In France, HIV testing can be easily performed in free and anonymous voluntary counselling testing (VCT) centres. The recent national study among French men who have sex with men (MSM) showed that 73% of those already tested for HIV had been tested in the previous two years. Nothing is known about the risk behaviours of MSM attending VCT centres. This study aimed to characterize sexual risk behaviours of MSM tested for HIV in such centres and identify factors associated with inconsistent condom use (ICU). A cross-sectional study was conducted from March to December 2009 in four VCT centres where a self-administered questionnaire was proposed to all MSM about to have a HIV test. ICU was defined as reporting non-systematic condom use during anal intercourse with casual male partners. Among the 287 MSM who fully completed their questionnaire, 44% reported ICU in the previous six months. Among those who had been already tested, 63% had had their test in the previous two years. Factors independently associated with ICU included: never avoiding one-night stands, not having been recently HIV tested, experiencing difficulty in using condoms when with a HIV negative partner or when under the influence of drugs or alcohol and finally, reporting to have had a large number of casual male partners in the previous six months. The rate of recently tested MSM was high in our study. Nevertheless, this rate was lower than that found in the last national study. Furthermore those not recently tested were significantly more likely to report high risk behaviours. We therefore recommend that further efforts be made to adapt the offer of both HIV testing and counselling to meet the specific needs of hard-to-reach MSM. Accordingly, an additional community-based offer of HIV testing to reach most-at-risk MSM is forthcoming in France.  相似文献

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.  相似文献

The rates, barriers, and outcomes of HIV serostatus disclosure to sexual partners are described for 245 female voluntary counseling and testing (VCT) clients in Dar es Salaam, Tanzania. VCT clients were surveyed 3 months after HIV testing to describe their HIV-serostatus disclosure experiences. Sixty-four percent of HIV-positive women and 79.5% of HIV-negative women (p = 0.028) reported that they had shared HIV test results with their partners. Among women who did not disclose, 52% reported the reason as fear of their partner's reaction. Both 81.9% of HIV-negative women and 48.9% of HIV-positive women reported that their partner reacted supportively to disclosure (p < 0.001). Less than 5% of women reported any negative reactions following disclosure. VCT should continue to be widely promoted. However, intervention approaches such as development of screening tools and new counseling approaches are important to ensure the safety of women who want to safely disclose HIV serostatus to their sexual partners.  相似文献

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.  相似文献

VCT has been shown to be an important HIV risk reduction strategy; however, little is known about who attends VCT or why people seek VCT. A retrospective analysis was performed on charts of 6330 clients who attended VCT between 1994 and 2002 at Y.R. Gaitonde Centre for AIDS Research and Education, a non-governmental organization in Chennai, Tamil Nadu, India. Most clients reported more than one reason for attending VCT, and the most commonly reported reasons were risk behavior, having symptoms, having a current HIV-positive partner, and reconfirming a previous positive HIV test. Reasons varied by gender and over time, and the likelihood of testing positive for HIV varied by reason reported. Understanding why people seek VCT informs an understanding of knowledge and attitudes about HIV and HIV testing, which has implications for the development of education, outreach and other HIV prevention services.  相似文献

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.  相似文献

The objective of this paper is to describe the baseline characteristics, risk behavior, and HIV prevalence of individuals and couples who enrolled in the Voluntary HIV Counseling and Testing Efficacy Study at the study site in Dar es Salaam, Tanzania. Participants were recruited through flyers, radio, and outreach to schools and workplaces to participate in a randomized clinical trial testing the effectiveness of HIV voluntary counseling and testing (HIV VCT) for prevention of new HIV and STD infections. Recruitment was stratified to include men and women enrolling alone and as couples. Baseline data were collected in face-to-face interviews, then participants were randomized to receive HIV VCT or health information. A total of 1,427 participants were recruited, 708 women and 719 men; 444 participants enrolled as part of a couple. HIV seroprevalence for those who received VCT at baseline was 21% overall (12% men, 30% women). Those enrolled as couples reported less sexual risk behavior than those enrolled as individuals. Both couples and individuals reported high rates of unprotected sexual intercourse with commercial partners. Overall 45% of participants self-reported an STD symptom (54% of women and 36% of men), and men were more likely to have received treatment for their symptoms. A large number of individuals and couples responded to advertisements for VCT in Dar es Salaam, Tanzania. High rates of HIV seroprevalence and couple serodiscordance, self-reported STD symptoms, and sexual risk behavior indicate that at-risk participants were recruited. Implications for delivery of HIV VCT and related services are discussed.  相似文献

OBJECTIVES: To estimate the prevalence of, and identify factors associated with, HIV testing in Britain. DESIGN: A large, stratified probability sample survey of sexual attitudes and lifestyles. METHODS: A total of 12,110 16-44 year olds completed a computer-assisted face-to-face interview and self-interview. Self-reports of HIV testing, i.e. the timing, reasons for and location of testing, were included. RESULTS: A total of 32.4% of men and 31.7% of women reported ever having had an HIV test, the majority of whom were tested through blood donation. When screening for blood donation and pregnancy were excluded, 9.0% of men and 4.6% of women had had a voluntary confidential HIV test (VCT) in the past 5 years. However, one third of injecting drug users and men who have sex with men had a VCT in the past 5 years. VCT in the past 5 years was significantly associated with age, residence, ethnicity, self-perceived HIV risk, reporting greater numbers of sexual partners, new sexual partners from abroad, previous sexually transmitted infection diagnosis, and injecting non-prescribed drugs for men and women, and same-sex partners (men only). Whereas sexually transmitted disease clinics were important sites for VCT, general practice accounted for almost a quarter of VCT. CONCLUSION: HIV testing is relatively common in Britain; however, it remains largely associated with population-based blood donation and antenatal screening programmes. In contrast, VCT remains highly associated with high-risk (sexual or drug-injecting) behaviours or population sub-groups at high risk. Strategies to reduce undiagnosed prevalent HIV infection will require further normalization and wider uptake of HIV testing.  相似文献

A study was conducted among individuals seeking voluntary HIV counselling and testing (VCT) in order to (a) describe their motives and source(s) of information, (b) describe their sexual behaviour; and (c) identify risk factors associated with HIV infection. Of 723 individuals who sought VCT, the most common reason (50%) was recent knowledge of HIV/AIDS and a desire to know their HIV status. The majority (77%) underwent VCT after being encouraged by others who knew their status. Ninety five per cent reported sexual encounters, with 337 (49%) engaging in unprotected sex. HIV prevalence was 31% and an HIV-positive status was associated with being female, being over 25 years of age and/or being a farmer. There is a demand for VCT, and the service provides an opportunity for intensive education about HIV/AIDS prevention on a one-to-one basis. It could also be an entry point to prevention and care for those who are infected.  相似文献

A venue-based HIV prevention study which included Voluntary Counseling and Testing (VCT) was conducted in three diverse areas of Kenya-Malindi, Nanyuki and Rachounyo. Aims of the study were to: (1) assess the acceptability of VCT for the general population, men who have sex with men (MSM), and injecting drug users (IDUs) within the context of a venue-based approach; (2) determine if there were differences between those agreeing and not agreeing to testing; and (3) study factors associated with being HIV positive. Approximately 98% of IDUs and 97% of MSM agreed to VCT, providing evidence that populations with little access to services and whose behaviors are stigmatized and often considered illegal in their countries can be reached with needed HIV prevention services. Acceptability of VCT in the general population ranged from 60% in Malindi to 48% in Nanyuki. There were a few significant differences between those accepting and declining testing. Notably in Rachuonyo and Malindi those reporting multiple partners were more likely to accept testing. There was also evidence that riskier sexual behavior was associated with being HIV positive for both men in Rachounyo and women in Malindi. Overall HIV prevalence was higher among the individuals in this study compared to individuals sampled in the 2008-2009 Kenya Demographic and Health Survey, indicating the method is an appropriate means to reach the highest risk individuals including stigmatized populations.  相似文献

This study investigates the self-reported history of HIV voluntary counseling and testing (VCT) among adults, aged 19–35 years, in northern Thailand. Participants were interviewed about their HIV testing history and risk behavior. Overall, 47% of 2251 participants had previously been tested, of whom 64% were tested at government clinics. Of those tested at private clinics, 50% reported not receiving pre- and post-test counseling, compared to 15% of those tested in government clinics. Ten percent of those tested had not received their test results. Among those who had never been previously tested for HIV, 66% believed they were not at risk, although 1.5% (2.7% among men) were HIV infected. Although VCT is widely available and utilized by the population of northern Thailand, substantial numbers of HIV infected persons have not been tested for HIV and among those tested many have not received comprehensive counseling. A Thai government policy enforcing effective counseling to accompany HIV testing is urgently needed.  相似文献

Correlates of individual HIV test results-seeking and utilization of partner counseling services were identified among male factory workers who participated in a longitudinal HIV prevention intervention study in Harare, Zimbabwe. Men working at participating factories were offered HIV voluntary counseling and testing (VCT) for themselves and their partners. While risk assessment counseling was offered in the workplace, result disclosure and partner counseling occurred at an off-workplace location. Of the 3,383 men undergoing risk assessment and testing, 1,903 (56%) chose to receive their test results and 230 (7%) brought their partners for VCT. Factors associated with receiving test results were history of STD and lower salary. Factors associated with bringing a partner for VCT were history of STD, being married, being employed at a factory with a peer educator, lower salary, and no prostitute contact. Incorporating VCT into STD treatment services is likely to reach a large number of men and their partners at highest risk for both types of infections. Because men are often the main decision-makers in sexual and reproductive matters, VCT must be easily accessible to urban, working African men.  相似文献
