The role of sexual compulsivity in unprotected intercourse among STI patients in Shanghai, China. BMC Public Health 2021; 21:141. [PMID: 33446160 PMCID: PMC7809841 DOI: 10.1186/s12889-021-10186-0] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2020] [Accepted: 01/06/2021] [Indexed: 11/10/2022] Open
Abstract
Background Sexual compulsivity (SC) and its relationship with unprotected intercourse (UI) have long been an intriguing topic, but its existential meaning in the management of public health or, more precisely, sexually transmitted infections (STIs) has rarely been studied to date. This study examines whether SC plays a role in UI among sexually active STI patients. Method A cross-sectional study was conducted in two sexual transmitted disease (STD) clinicals of Shanghai Skin Diseases Hospital in Shanghai. Totally 664 sexually active STI patients were included. Results The ages of the 664 participants ranged from 18 to 76 years, with 58.73% between 26 and 40 years old. 449 (191 male and 258 female) reported had UI during the past 6 months. Although the only statistically significant difference (p < 0.01) was in relation to UI with a casual sexual partner, the difference between male/female and regular/casual sexual partners remained evident. Conclusions SC is evidently a potential predictor of UI with a casual sexual partner in male STI patients, while the use of condoms is more likely to be affected by other factors. In addition to general sexual education, counseling interventions should be provided by health institutions, and specific intervention methods targeting gender and sexual partners should be considered.

Abstract
Along with other partners of key population groups, men who purchase sex (MWPS) contributed to around 18% of new reported HIV cases in 2018 among people aged 15-49 years worldwide. A systematic review was performed to evaluate interventions conducted to reduce HIV risk among MWPS in low- and middle-income countries (LMICs). A comprehensive search of studies published in Embase, Medline, Global Health, Scopus, and Cinahl was performed. Among 32,115 studies found, 21 studies met the review's inclusion criteria. Only four studies recruited MWPS, while the rest recruited groups often used as proxy populations for MWPS. The interventions were made primarily to increase HIV-related knowledge or perceptions through education and to improve condom usage rates through promotion and distribution. Few studies evaluated the impact of interventions on HIV testing rates and none looked at HIV treatment. Given the important role of testing as a prevention gate, together with UNAIDS' 90-90-90 testing and treatment coverage goals for people infected with HIV, more studies which evaluate the impact of HIV testing and treatment provision among this group are needed.

Abstract
This study assesses the results of a 2-year community-based peer education program aimed at increasing HIV/AIDS knowledge, attitudes toward condoms, and condom use behavior among taxicab and tricycle drivers in the Philippines. Pretest, posttest, and follow-up data were collected throughout the educational intervention program. The results of the repeated measures analysis of variance (ANOVA) indicate a significant change on knowledge about HIV/AIDS from baseline to posttest and from posttest to follow-up ( F= 449.27, df= 2, p< .001). There was also a significant change on attitudes about condom use from baseline to posttest and from posttest to follow-up ( F= 425.19, df= 2, p= 0.001), and a significant effect on condom use behavior with commercial sex workers from baseline to posttest and follow-up ( F= 428.31, df= 2, p= .001). The peer-mediated intervention was found to be an effective means of HIV/AIDS prevention among taxi and tricycle drivers in the Philippines.

Abstract
This paper examines whether a peer group intervention that reduced self-reported risky behaviors for rural adults in Malawi also had impacts on non-participants in the same communities. We randomly assigned two districts to the intervention and control conditions, and conducted surveys at baseline and 18 months post-intervention using unmatched independent random samples of intervention and control communities in 2003-2006. The six-session peer group intervention was offered to same-gender groups by trained volunteers. In this analysis, we divided the post-intervention sample into three exposure groups: 243 participants and 170 non-participants from the intervention district (total n = 415) and 413 control individuals. Controlling for demographics and participation, there were significant favorable diffusion effects on five partially overlapping behavioral outcomes: partner communication, ever used condoms, unprotected sex, recent HIV test, and a community HIV prevention index. Non-participants in the intervention district had more favorable outcomes on these behaviors than survey respondents in the control district. One behavioral outcome, community HIV prevention, showed both participation and diffusion effects. Participating in the intervention had a significant effect on six psychosocial outcomes: HIV knowledge (two measures), hope, condom attitudes, and self-efficacy for community HIV prevention and for safer sex; there were no diffusion effects. This pattern of results suggests that the behavioral changes promoted in the intervention spread to others in the same community, most likely through direct contact between participants and non-participants. These findings support the idea that diffusion of HIV-related behavior changes can occur for peer group interventions in communities, adding to the body of research supporting diffusion of innovations theory as a robust approach to accelerating change. If diffusion occurs, peer group intervention may be more cost-effective than previously realized. Wider implementation of peer group interventions can help meet the global goal of reducing new HIV infections.

Abstract
HIV epidemics spread rapidly through Asian sex work networks two decades ago under conditions of high vulnerability, low condom use, intact male foreskins and ulcerative STIs. Experiences implementing interventions to prevent transmission in sex work in ten Asian countries were reviewed. All report increasing condom use trends in sex work. In the seven countries where condom use exceeds 80%, surveillance and other data indicate declining HIV trends or low and stable HIV prevalence with declining STI trends. All four countries with national-level HIV declines among sex workers have also documented significant HIV declines in the general population. While all interventions in sex work included outreach, condom programing and STI services, the largest declines were found in countries that implemented structural interventions on a large scale. Thailand and Cambodia, having controlled transmission early, are closest to providing universal access to HIV care, support and treatment and are exploring HIV elimination strategies.

Abstract
Despite extensive early prevention efforts, recent surveys suggest that sexual risk taking may again be on the rise in Thailand. The present cross-sectional study surveyed 3,299 recruits in the Thai Navy in 2010, to examine their rates and correlates of consistent condom use. Most participants were aged 21-22 years, unmarried, and had a secondary education. Almost half were employed in labor/agriculture. Only 17 % of sexually experienced recruits were consistent condom users, and 53 % reported multiple sex partners in the past 3 months. In multiple logistic regression, residence in the Northeast (AOR 1.47), age (AOR 1.43), being single (AOR 2.13), non-MSM status (AOR 1.41), voluntary testing (AOR 1.24), and condom use at first sex (AOR 4.29) were significantly associated with consistent condom use. These findings suggest gaps in Thailand's condom campaign targeting both sexually experienced and inexperienced youth. Interventions targeting naval recruits may benefit from including sex education in the training curriculum, building drillmasters' capacities to facilitate sex education/counseling, and creating a supportive environment with better access to condoms.

Abstract
For a country with a moderate adult HIV prevalence of just over 1% in 2012, Thailand is widely perceived as having made some extraordinary contributions to the global management of the HIV/AIDS pandemic. It has been promoted as a model of effective HIV control and applauded for its leadership in providing access to antiretroviral treatment. Thailand has also received international recognition for its contribution to biomedical HIV prevention research, which is generally perceived as exceptional. In this paper, Thailand's global role model function as an example of effective HIV/AIDS control and high-quality biomedical HIV prevention research is re-evaluated against the background of currently available data and more recent insights. The results indicate that Thailand's initial response in raising the level of the political significance of HIV/AIDS was indeed extraordinary, which probably prevented a much larger epidemic from occurring. However, this response transpired in unusual extraconstitutional circumstances and its effectiveness declined once the country returned to political normalcy. Available data confirm the country's more than exceptional contribution to biomedical HIV prevention research. Thailand has made a huge contribution to the global management and control of the HIV/AIDS pandemic.

Abstract
BACKGROUND Opinion leaders are often local individuals with high credibility who can influence other people. Robust effects using opinion leaders in diffusing innovations have been shown in several randomized controlled trials, for example regarding sexually transmitted infections (STI), human immunodeficiency virus (HIV) prevention, mammography rates and caesarean birth delivery rates. In a Cochrane review 2010 it was concluded that the use of opinion leaders can successfully promote evidence-based practice. Thus, using opinion leaders within the public health sector might be one means to speed up the dissemination of health promoting and disease preventing innovations. Social network analysis has been used to trace and map networks, with focus on relationships and positions, in widely spread arenas and topics. The purpose of this study was to use social network analysis in order to identify potential opinion leaders at the arena of child health promotion in Sweden. RESULTS By using snowball technique a short e-mail question was spread in up to five links, starting from seven initially invited persons. This inquiry resulted in a network consisting of 153 individuals. The most often mentioned actors were researchers, public health officials and paediatricians, or a combination of these professions. Four single individuals were mentioned by five to seven other persons in the network. These individuals obviously possess qualities that make other professionals within the public health sector listen to and trust them. CONCLUSIONS Social network analysis seemed to be a useful method to identify influential persons with high credibility, i.e. potential opinion leaders, at the arena of child health promotion in Sweden. If genuine opinion leaders could be identified directed measures can be carried out in order to spread new and relevant knowledge. This may facilitate for public health actors at the local, regional and national level to more rapidly progress innovations into everyday practice. However, effectiveness studies of opinion leaders in the public health sector still have to be performed.

Abstract
BACKGROUND The workplace provides an important avenue to prevent HIV. OBJECTIVES To evaluate the effect of behavioral interventions for reducing HIV on high risk sexual behavior when delivered in an occupational setting. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE and PsycINFO up until March 2011 and CINAHL, LILACS, DARE, OSH Update, and EPPI database up until October 2010. SELECTION CRITERIA Randomised control trials (RCTs) in occupational settings or among workers at high risk for HIV that measured HIV, sexual transmitted diseases (STD), Voluntary Counseling and Testing (VCT), or risky sexual behaviour. DATA COLLECTION AND ANALYSIS Two reviewers independently selected studies for inclusion, extracted data and assessed risk of bias. We pooled studies that were similar. MAIN RESULTS We found 8 RCTs with 11,164 participants but one study did not provide enough data. Studies compared VCT to no VCT and education to no intervention and to alternative education.VCT uptake increased to 51% when provided at the workplace compared to a voucher for VCT (RR=14.0 (95% CI 11.8 to16.7)). After VCT, self-reported STD decreased (RR = 0.10 (95% CI 0.01 to 0.73)) but HIV incidence (RR=1.4 (95% CI 0.7 to 2.7)) and unprotected sex (RR=0.71 (0.48 to 1.06)) did not decrease significantly. .Education reduced STDs (RR = 0.68 (95%CI 0.48 to 0.96)), unprotected sex (Standardised Mean Difference (SMD)= -0.17 (95% CI -0.29 to -0.05), sex with a commercial sex worker (RR = 0.88 (95% CI 0.81 to 0.96) but not multiple sexual partners (Mean Difference (MD) = -0.22 (95% CI -0.52 to 0.08) nor use of alcohol before sex (MD = -0.01 (95% CI of -0.11 to 0.08). AUTHORS' CONCLUSIONS Workplace interventions to prevent HIV are feasible. There is moderate quality evidence that VCT offered at the work site increases the uptake of testing. Even though this did no lower HIV-incidence, there was a decrease in self-reported sexual transmitted diseases and a decrease in risky sexual behaviour. There is low quality evidence that educational interventions decrease sexually transmitted diseases, unprotected sex and sex with commercial sex workers but not sex with multiple partners and the use of alcohol before sex.More and better randomised trials are needed directed at high risk groups such as truck drivers or workers in areas with a very high HIV prevalence such as Southern Africa. Risky sexual behaviour should be measured in a standardised way.

Abstract
The HIV/AIDS epidemic continues to grow in pockets across Asia, despite early successes at curtailing its spread in countries like Thailand. Recent evidence documents dramatic increases in incidence among risk groups and, alarmingly, the general population. This meta-analysis summarizes the sexual risk-reduction interventions for the prevention of HIV-infection that have been evaluated in Asia. Sexual risk-reduction outcomes (condom use, number of sexual partners, incident sexually transmitted infections [STI], including HIV) from 46 behavioral intervention studies with a comparison condition and available by August 2010 were included. Overall, behavioral interventions in Asia consistently reduced sexual risk outcomes. Condom use improved when interventions sampled more women, included motivational content, or did not include STI testing and treatment. Incident HIV/STI efficacy improved most when interventions sampled more women, were conducted more recently, or when they included STI counseling and testing. Sexual frequency efficacy improved more in interventions that were conducted in countries with lower human development capacities, when younger individuals were sampled, or when condom skills training was included. Behavioral interventions for reducing sexual risk in Asia are efficacious; yet, the magnitude of the effects co-varies with specific intervention and structural components. The impact of structural factors on HIV intervention efficacy must be considered when implementing and evaluating behavioral interventions. Implications and recommendations for HIV/AIDS interventions are discussed.

Abstract
In 2008, 400 males ≥18 years old who paid or traded for sex with a female sex worker (FSW) in Tijuana, Mexico, in the past 4 months completed surveys and HIV/STI testing; 30 also completed qualitative interviews. To analyze environmental sources of HIV vulnerability among male clients of FSWs in Tijuana, we used mixed methods to investigate correlates of clients who met FSWs in nightlife venues and clients' perspectives on venue-based HIV risk. Logistic regression identified micro-level correlates of meeting FSWs in nightlife venues, which were triangulated with clients' narratives regarding macro-level influences. In a multivariate model, offering increased pay for unprotected sex and binge drinking were micro-level factors that were independently associated with meeting FSWs in nightlife venues versus other places. In qualitative interviews, clients characterized nightlife venues as high risk due to the following macro-level features: social norms dictating heavy alcohol consumption; economic exploitation by establishment owners; and poor enforcement of sex work regulations in nightlife venues. Structural interventions in nightlife venues are needed to address venue-based risks.

Abstract
For decades, the Roman Catholic Church opposed use of condoms to prevent spread of sexually transmitted infections (STI) because of their contraceptive effect. In 2009, Pope Benedict XVI said that widespread use of condoms could worsen the situation, a position rejected as 'unscientific'. Recently, however the Pontiff stated that because the Church considers acts of prostitution and homosexuality to be gravely immoral and disordered, in such specific cases use of a condom might become an initial step in the direction of a moralization leading to an assumption of responsibility and a new awareness of the meaning of sexuality. In doing so, he reaffirmed his belief that condoms cannot solve the problem of STI spread, stressing the Church's position that modern societies no longer see sexuality as an 'expression of love, but only as a sort of drug that people administer to themselves'. The new Papal position has been widely applauded, but made conservative Catholics unhappy. A dialogue with the Church now seems possible: Does concentrating on condoms hinder the effectiveness of other strategies? What are the respective roles of condoms and other approaches to prevent infection spread? Does a special situation exist in Africa requiring specific and focused interventions?

Abstract
OBJECTIVES We examined findings from a randomized controlled intervention trial designed to improve the quality of life of people living with HIV in Thailand. METHODS A total of 507 people living with HIV were recruited from 4 district hospitals in northern and northeastern Thailand and were randomized to an intervention group (n = 260) or a standard care group (n = 247). Computer-assisted personal interviews were administered at baseline and at 6 and 12 months. RESULTS At baseline, the characteristics of participants in the intervention and standard care conditions were comparable. The mixed-effects models used to assess the impact of the intervention revealed significant improvements in general health (B = 2.51; P = .001) and mental health (B = 1.57; P = .02) among participants in the intervention condition over 12 months and declines among those in the standard care condition. CONCLUSIONS Our results demonstrate that a behavioral intervention was successful in improving the quality of life of people living with HIV. Such interventions must be performed in a systematic, collaborative manner to ensure their cultural relevance, sustainability, and overall success.

To prompt policymakers to revitalize HIV prevention, this study identifies a comprehensive list of HIV/AIDs preventive interventions that are likely to be effective and cost-effective in Thailand. Methods A systematic review of the national and international literature on HIV prevention strategies from 1997 to 2008 was undertaken. The outcomes used to consider the effectiveness of HIV prevention interventions were changes in HIV risk behaviour and HIV incidence. Economic evaluations that presented their results in terms of cost per HIV infection averted or cost per quality-adjusted life year (QALY) gained were also included. All studies were assessed against quality criteria. Results The findings demonstrated that school based-sex education plus life-skill programs, voluntary and routine HIV counselling and testing, male condoms, street outreach programs, needle and syringe programs, programs for the prevention of mother-to-child HIV transmission, male circumcision, screening blood products and donated organs for HIV, and increased alcohol tax were all effective in reducing HIV infection among target populations in a cost-effective manner. Conclusion We found very limited local evidence regarding the effectiveness of HIV interventions amongst specific high risk populations. This underlines the urgent need to prioritise health research resources to assess the effectiveness and cost-effectiveness of HIV interventions aimed at reducing HIV infection among high risk groups in Thailand.

Abstract
Despite their crucial role in HIV infection and transmission, commercial sex male clients (CSMCs) are rarely studied. The purpose of this study was to examine the relationship between peer norms and consistent condom use with female sex workers (FSWs) among CSMCs in Sichuan province, China. Male clients with peers who had paid for sex (n = 562) were recruited by local health workers through snowball sampling. Measures of peer norms included 1) descriptive norms which were evaluated by perceptions of peer's condom attitudes and behaviors with FSWs; 2) injunctive norms which were assessed by the perceived peer approval of using condoms with FSWs; and 3) communication of HIV-related topics with peers. The outcome was consistent condom use with FSWs. Results of multivariate logistic regression models revealed that consistent condom use with FSWs was significantly more likely among male clients who perceived more pro-condom descriptive and injunctive norms among their peer groups. In addition, the pattern of commercial sex visits moderated the relations between peer norms and consistent condom use with FSWs. More peer approval of condom use and more HIV-related communication were significantly associated with consistent condom use among clients who visited FSWs with friends but not among those who visited FSWs alone. The findings suggest that social activities surrounding commercial sex visits may provide an entry point for HIV prevention intervention with men who patronize FSWs and that such efforts should tap into existing dynamics of social interaction to promote pro-condom norms.

Abstract
OBJECTIVE To examine the relative importance of harassment-tolerant norms emanating from troops senior officers, immediate supervisors, and units on troops' sexual stressor experiences and to see whether associations differed by sex. METHOD Cross-sectional survey of all 681 willing and confirmed active duty troops enrolled in the VA National Enrollment Database between 1998 and 2002. Findings extended an earlier analysis. RESULTS After adjusting for other significant correlates, senior officers' perceived tolerance of sexual harassment was not associated with the severity of sexual harassment troops reported (p = 0.64) or with the numbers of sexual identity challenges they reported (p = 0.11). Harassment-tolerant norms emanating from troops' units and immediate supervisors were associated with reporting more severe sexual harassment and more sexual identity challenges (all p < 0.003). Findings generalized across sex. CONCLUSIONS Senior officers' norms did not appear to affect troops' reports of military sexual stressors, but unit norms and immediate supervisors' norms did.

Abstract
In 2005, the New York City Department of Health and Mental Hygiene (DOHMH) made free condoms available to organizations through a Web-based ordering system. In 2006, we interviewed managers and patrons about free condom availability, acquisition, and use in venues where people at high risk for human immunodeficiency virus congregate. DOHMH condom distribution increased from 5.8 million in 2004 to 17.3 million in 2006. Overall, managers reported making condoms available at 76% (309/409) of high-priority venues, but only at 40% of gay bars. Among patrons who saw free condoms, 80% (280/351) reported taking them; 73% (205/280) of those who reported taking them also reported using them. A simple, Web-based ordering system dramatically increased condom distribution. In the venues we sampled, the majority of patrons acquired and used free condoms when available and visible, suggesting that increasing free condom availability may increase use. Special efforts are needed to ensure availability at gay bars.

Abstract
Male partners of female sex workers are rarely targeted by HIV prevention interventions in the commercial sex industry, despite recognition of their central role and power in condom use negotiation. Social networks offer a naturally existing social structure to increase male participation in preventing HIV. The purpose of this study was to explore the relationship between social network norms and condom use among male partners of female sex workers in La Romana, Dominican Republic. Male partners (N =318) were recruited from 36 sex establishments to participate in a personal network survey. Measures of social network norms included 1) perceived condom use by male social network members and 2) encouragement to use condoms from social network members. Other social network characteristics included composition, density, social support, and communication. The primary behavioral outcome was consistent condom use by male partners with their most recent female sex worker partner during the last 3 months. In general, men reported small, dense networks with high levels of communication about condoms and consistent condom use. Multivariate logistic regression revealed consistent condom use was significantly more likely among male partners who perceived that some or all of their male social network members used condoms consistently. Perceived condom use was, in turn, significantly associated with dense networks, expressing dislike for condoms, and encouragement to use condoms from social network members. Findings suggest that the tight social networks of male partners may help to explain the high level of condom use and could provide an entry point for HIV prevention efforts with men. Such efforts should tap into existing social dynamics and patterns of communication to promote pro-condom norms and reduce HIV-related vulnerability among men and their sexual partners.

Abstract
Background The BED IgG-Capture Enzyme Immunoassay (cBED assay), a test of recent HIV infection, has been used to estimate HIV incidence in cross-sectional HIV surveys. However, there has been concern that the assay overestimates HIV incidence to an unknown extent because it falsely classifies some individuals with non-recent HIV infections as recently infected. We used data from a longitudinal HIV surveillance in rural South Africa to measure the fraction of people with non-recent HIV infection who are falsely classified as recently HIV-infected by the cBED assay (the long-term false-positive ratio (FPR)) and compared cBED assay-based HIV incidence estimates to longitudinally measured HIV incidence. Methodology/Principal Findings We measured the long-term FPR in individuals with two positive HIV tests (in the HIV surveillance, 2003–2006) more than 306 days apart (sample size n = 1,065). We implemented four different formulae to calculate HIV incidence using cBED assay testing (n = 11,755) and obtained confidence intervals (CIs) by directly calculating the central 95th percentile of incidence values. We observed 4,869 individuals over 7,685 person-years for longitudinal HIV incidence estimation. The long-term FPR was 0.0169 (95% CI 0.0100–0.0266). Using this FPR, the cross-sectional cBED-based HIV incidence estimates (per 100 people per year) varied between 3.03 (95% CI 2.44–3.63) and 3.19 (95% CI 2.57–3.82), depending on the incidence formula. Using a long-term FPR of 0.0560 based on previous studies, HIV incidence estimates varied between 0.65 (95% CI 0.00–1.32) and 0.71 (95% CI 0.00–1.43). The longitudinally measured HIV incidence was 3.09 per 100 people per year (95% CI 2.69–3.52), after adjustment to the sex-age distribution of the sample used in cBED assay-based estimation. Conclusions/Significance In a rural community in South Africa with high HIV prevalence, the long-term FPR of the cBED assay is substantially lower than previous estimates. The cBED assay performs well in HIV incidence estimation if the locally measured long-term FPR is used, but significantly underestimates incidence when a FPR estimate based on previous studies in other settings is used.

Abstract
This paper makes five key points. First is that the aggregate effect of radical and sustained behavioural changes in a sufficient number of individuals potentially at risk is needed for successful reductions in HIV transmission. Second, combination prevention is essential since HIV prevention is neither simple nor simplistic. Reductions in HIV transmission need widespread and sustained efforts, and a mix of communication channels to disseminate messages to motivate people to engage in a range of options to reduce risk. Third, prevention programmes can do better. The effect of behavioural strategies could be increased by aiming for many goals (eg, delay in onset of first intercourse, reduction in number of sexual partners, increases in condom use, etc) that are achieved by use of multilevel approaches (eg, couples, families, social and sexual networks, institutions, and entire communities) with populations both uninfected and infected with HIV. Fourth, prevention science can do better. Interventions derived from behavioural science have a role in overall HIV-prevention efforts, but they are insufficient when used by themselves to produce substantial and lasting reductions in HIV transmission between individuals or in entire communities. Fifth, we need to get the simple things right. The fundamentals of HIV prevention need to be agreed upon, funded, implemented, measured, and achieved. That, presently, is not the case.

Abstract
We developed and evaluated a military-focused HIV prevention intervention to enhance HIV risk-reduction knowledge, motivation, and behaviors among Angolan soldiers. Twelve bases were randomly assigned to HIV prevention or control conditions, yielding 568 participants. HIV prevention participants received training in preventing HIV (4.5 days) and malaria (0.5 days). Control participants received the reverse. Monthly booster sessions were available after each intervention. We assessed participants at baseline, 3 and 6 months after the training. HIV prevention participants reported greater condom use and less unprotected anal sex at 3 months, as well as greater HIV-related knowledge and perceived vulnerability at 3 and 6 months. Within-group analyses showed HIV prevention participants increased condom use, reduced unprotected vaginal sex, and reduced numbers of partners at both follow-ups, while control participants improved on some outcomes at 3 months only. A military-focused HIV prevention intervention may increase HIV-related knowledge, motivation, and risk reduction among African soldiers.

Abstract
Northern Thailand has been the epicentre of a largely heterosexually transmitted HIV epidemic that has recently involved married women. In preparation for HIV-prevention trials, we investigated patterns of HIV and syphilis risk through annually measured HIV and syphilis prevalence among northern Thai, peri-urban, community-dwelling men (n=2564) and women (n=3907) aged 18-35 years between 1998 and 2001. Crude HIV and syphilis prevalence were 3.3% and 2.7% for men and 2.3% and 2.1% for women, respectively. In logistic regression models of HIV and syphilis, compared with married men/women, widowers and widows were at increased risk (odds ratio; 95% confidence interval) of syphilis (7.86; 1.56-39.6 and 3.3; 1.14-9.61, respectively) and HIV (12.68; 3.23-49.8 and 41.3; 24.3-70.3, respectively). The oldest women were at lower risk of HIV (0.43; 0.22-0.85). For men and women, those with syphilis were approximately three times more likely to have HIV. These unique population data illustrate evolving sex parity of HIV burden in northern Thailand.

Abstract
Asia has the highest numbers of tuberculosis cases (60% of the global total) and has experienced a marked rise in HIV seroprevalence (22% of the global total) in key subpopulations of these highly populous nations. Thus, co-infected patients are a challenge for practitioners and public health workers alike. The U.S.-Japan Cooperative Medical Science Program is spearheading interdisciplinary collaborations in Asia to address the many outstanding research priorities for HIV-tuberculosis co-infection. There is an urgency to this agenda for many reasons, including the frequency with which tuberculosis accounts for the death of HIV-infected persons in Asia, and the continued rise of multiple drug-resistant Mycobacterium tuberculosis. We review briefly the public health situation in Asia, highlighting research questions from US-Japan-Asian partner joint meetings, and cite salient studies to indicate trends and challenges.

Abstract
Counseling for participants in preventive HIV vaccine trials has been an area of continuing concern because of the need to address possible behavioral side effects (e.g., increased risk behavior because trial participants believe they may have received an active, effective vaccine) and social harms (e.g., discrimination in health care or employment because of vaccine-induced seropositivity on commercial HIV tests). Yet, the data on behavioral effects and social harms are limited and rather little detail has been provided regarding the counseling provided in current or past trials. This paper summarizes conceptual, cultural, and practical considerations in the development of a counseling program for HIV vaccine trials and provides examples from work done in the context of Phase I/II vaccine trials in Thailand.

Abstract
OBJECTIVE To estimate the incidence of HIV and study the impact of risk-reduction counseling (RRC) in a cohort of people with high-risk behavior for HIV transmission in Chennai, India. DESIGN Prospective cohort follow-up of 500 HIV-negative people (250 men and 250 women) at increased risk for HIV acquisition in Chennai, India for a maximum of 1 year was conducted. They received RRC at 0, 6, and 12 months. Generalized estimating equation methodology was used to determine the statistical significance of differences reported in behavior between baseline, 6 months, and 12 months. RESULTS The overall HIV incidence in this cohort was 0.44 per 100 person-years (95% confidence interval: 0.05-1.60). In the course of the study, both male and female participants reported statistically significant decreases in the number of different sexual partners, the number of new partners, and the proportion of sexual encounters with nonprimary partners. Participants who had more than 3 different partners at baseline and/or exchanged money for sex in the 6 months before enrollment demonstrated the greatest reductions in the number of different sexual partners. CONCLUSIONS Individualized sexual RRC seems to be a useful intervention to reduce risk-taking behavior among at-risk heterosexuals in India.

Abstract
Effective STD and HIV prevention requires synergism of individual-based prevention behaviors and societal/structural supports that will promote and maintain these behaviors. We should also expect the unexpected. STD rates in gay men have risen after effective prevention of HIV/STD in gay men and effective antiretroviral therapy. New drugs of abuse, such as methamphetamine ("crystal meth"), have induced risky sexual behaviors in gay and heterosexual communities. Economic dislocation in Eastern Europe has resulted in trafficking of commercial sex workers to Europe, the Mideast, and Asia, all with the potential for STD and HIV spread. James Curran, formerly director of the HIV epidemiology and prevention effort at the CDC, has written: It is ironic that the two clearest examples of large-scale success in HIV prevention-reduction in HIV transmission in gay men in the United States and national declines in HIV incidence in Thailand-arise in societies/communities known in their own way for sexual openness....the openness in both communities provided the environment to make the powerful revolutionary changes needed. In Africa, the powerful voice of President Museveni of Uganda has also encouraged candor about sexual risk-taking and facilitated that nation's encouraging early success in reducing HIV prevalence...Unfortunately, most of the world remains unable or unwilling to deal frankly and consistently with sexuality despite the considerable risks of HIV infection in many communities. There is a worldwide sexual hangup hampering HIV prevention efforts.

Abstract
BACKGROUND Previous reviews of interventions to prevent sexually transmitted infections (STIs) focused mostly on human immunodeficiency virus (HIV) infection. We reviewed trials of interventions to prevent sexual transmission of any STI, employing a multilevel perspective. METHODS We searched MEDLINE, the Cochrane Central Register of Controlled Trials, and recent unpublished presentations through 2003, to identify randomized controlled trials of preventive STI interventions having systematic, objective measurement of STI outcomes. We classified trials according to intervention target and level of randomization (individual, group, or community); impact target (acquisition, transmission, or complications of STI); and primary intervention modality. RESULTS Of 83 trials identified, 41 met inclusion criteria, including trials of 28 individual-level, 9 group-level, and 4 community-level interventions. Among individual- and group-level interventions, 32 targeted acquisition, 4 targeted transmission, and 1 targeted complications of STI. The 4 intervention modalities most often used included behavior change (12 studies), vaccination (7 studies), use of topical microbicides (10 studies), and prophylactic, curative, or suppressive therapy (10 studies). Community-level interventions had multiple impact targets, and 2 interventions used multiple modalities. Only 1 intervention showed efficacy against sexual transmission of HIV, but 22 (53.7%) showed effectiveness against other STIs. CONCLUSION Although many interventions have been found to be effective against STIs, few have been replicated, widely implemented, or carefully evaluated for effectiveness in other settings.

Abstract
BACKGROUND Sexually transmitted disease (STD), including AIDS, disproportionately affects African-American and Hispanic women. GOAL To evaluate efficacy of standard and enhanced (addition of optional support groups) gender- and culture-specific, small-group behavioral interventions, compared to interactive STD counseling, in high risk minority women for two years. METHODS Women with a non-viral STD were treated and enrolled in a randomized trial. Follow-up screens and interviews occurred at 6 months, 1 year, 18 months (short interview, optional exam) and 2 years. The primary outcome was subsequent infection with chlamydia and/or gonorrhea. Secondary outcomes included risky sexual behaviors. We employed logistic regression based on intention-to-treat. RESULTS Data from 775 women were included; the retention rate was 91%. Adjusted infection rates were higher in the controls in Year 1 (26.8%), Year 2 (23.1%), and cumulatively (39.8%) than in the enhanced (15.4%, P = 0.004; 14.8%, P < 0.03; 23.7%, P < 0.001, respectively) and standard (15.7%, P = 0.006; 14.7%, P = 0.03; 26.2%, P < 0.008, respectively) intervention arms at these time points. Enhanced-intervention women who opted to attend support groups (attendees) had the lowest adjusted infection rates in Year 1 (12.0%) and cumulatively (21.8%). Intervention women in general, but particularly attendees, were significantly less likely than controls to have repeat infections. Multiple partners and unprotected sex with an untreated or incompletely treated partner helped explain group differences in infection. CONCLUSIONS Risk-reduction interventions significantly decreased both single and multiple infective episodes with chlamydia and/or gonorrhea and risky sexual behaviors in the two-year study period. Support-group attendance appeared to contribute additional risk reduction in Year 1.

Abstract
Thailand's comprehensive national response to the HIV/AIDS epidemic has been extensively documented since the beginning of epidemic. Substantial progress in the fight against HIV/AIDS has been made because awareness of the problem was raised. Top-level political commitment and multisectoral strategies mobilized funds and human resources to implement the control program at all levels. Behavioral change resulting in increased condom use in brothels on a national scale rose from virtually nil to more than 95%. This was accompanied by a 90% reduction of the sexually transmitted disease rate. In parallel, the rate of new HIV infections dropped by 80%. Despite these achievements, there remains an urgent need to continue efforts to ensure universal and unfailing condom use. Further, Thailand needs to establish pragmatic innovative approaches to reduce transmission, especially among injection drug users, women, and youth, as well as to develop effective strategies for implementation of antiretroviral treatment. Further strategies also need to consider the changing cultural, social, and economic characteristics of the Thai populations.

Abstract
Despite the remarkable advances that have been made in the last 20 years regarding the molecular virology, pathogenesis and epidemiology of HIV, the development of an effective HIV vaccine remains an elusive goal. The major reason for this is that we have not determined a correlate of immunity. The various explantations for this include integration of the virus into the host cell genome, infection of long-lived immune cells, HIV genetic diversity (especially in its envelope), persistent high viral replication releasing up to 10 billion viral particles per day and/or production of immunosuppressive products or proteins. However, there is evidence that the host can be protected: some highly exposed persons have remained uninfected; the relatively low incidence of mother to child (fetus) transmission; the initial effective immune response that significantly, if temporally, reduces viral loads; some infected persons are long-term non-progressors; experimental vaccines and passive immunisation have proven effective in experimental animals; and finally, successful vaccine development against other viral infections. At this time, the experimental vaccine pipeline is quite robust and ranges from HIV proteins (although the first such vaccine, recombinant gp120 made on Chinese hamster ovary cells, failed to protect volunteer men having sex with men [MSM]) to DNA vaccines and various novel delivery strategies. Perhaps the greatest impediment is the requirement to test these experimental vaccines in resource-poor developing countries that, at present, lack the necessary infrastructure for performing large, long-term, scientifically valid studies.

Abstract
As the HIV/AIDS epidemic continues its relentless spread in many parts of the world, DOI provides a useful framework for analyzing the difficulties in achieving behavior change necessary to reduce HIV rates. The DOI concepts most relevant to this question include communication channels, the innovation-decision process, homophily, the attributes of the innovation, adopter categories, and opinion leaders. The preventive measures needed to halt the transmission of HIV constitute a "preventive innovation." This article describes the attributes of this preventive innovation in terms of relative advantage, compatibility, complexity, trialability, and observability. It reviews studies that incorporated DOI into HIV/AIDS behavior change interventions, both in Western countries and in the developing world. Finally, it discusses possible reasons that the use of DOI has been fairly limited to date in HIV/AIDS prevention interventions in developing countries.

Abstract
Investigation of sexual behavior involves many challenges, including how to assess sexual behavior and how to analyze the resulting data. Sexual behavior can be assessed using absolute frequency measures (also known as counts) or with relative frequency measures (e.g., rating scales that range from never to always). We discuss these 2 assessment approaches in the context of research on HIV risk behavior. We conclude that these 2 approaches yield nonredundant information and, more important, that only data yielding information about the absolute frequency of risk behavior have the potential to serve as valid indicators of HIV contraction risk. However, analyses of count data may be challenging because of non-normal distributions with many outliers. Therefore, we identify new and powerful data analytical solutions that have been developed recently to analyze count data and discuss limitations of a commonly applied method (viz., analysis of covariance using baseline scores as covariates).

Abstract
OBJECTIVES To examine the association between HIV infection and tuberculosis (TB) and the proportion of TB attributable to HIV in Chiang Rai province, northern Thailand, in response to a rapidly changing incidence of HIV infection. METHODS Case-control study covering the period 1990 to 1998. Cases were all new TB patients seen at Chiang Rai Hospital. Controls were antenatal clinic attendees, delivery patients, surgical patients, blood donors, and military conscripts. Odds ratios (ORs) were calculated by year, age group, and sex, using each control group separately. The population attributable fraction was calculated by year. RESULTS During the study period, the number of new TB cases in Chiang Rai Hospital increased more than threefold. The ORs increased over time compared with all control groups for both sexes but did not vary consistently with age. The proportion of TB cases attributable to HIV rose to 72.0% in male patients and 65.8% in female patients by 1998. CONCLUSIONS The HIV epidemic has a profound and prolonged impact on TB burden. Despite the marked reduction in HIV incidence already seen in Chiang Rai, the HIV prevalence among TB cases and the proportion of cases attributable to HIV continue to rise.

Abstract
OBJECTIVES Willingness to participate in HIV-1 vaccine trials and associated factors were investigated in a sample of 2670 Royal Thai Army conscripted recruits. METHODS Self administered questionnaires were used. Data were collected during the final visit of a longitudinal cohort study of HIV-1 epidemiology. Cross sectional analysis of data from this visit was performed. RESULTS 32% of the respondents reported they would "definitely" join an HIV-1 vaccine trial. Greater willingness was associated with perceived risk of HIV-1 infection and a desire to help Thai society, although tangible incentives and intentions to reduce condom use in a vaccine trial also were associated with increased willingness. Concerns about physical harm and anticipated social pressure from family not to join were the most substantial impediments to willingness. Concerns about "social harm" (for example, participation would give appearance of having AIDS virus, a partner might refuse sex) also appeared to inhibit interest in joining trials and approached significance. CONCLUSIONS Willingness to participate was somewhat greater than in other investigations of non-injection drug user (IDU) cohorts in Thailand, with fewer concerns expressed about physical harm. Motivations appear to involve tradeoffs among perceived risk, anticipated social pressure, altruism, and tangible rewards. The absence of significant problems associated with vaccine trials to date, along with the presence of educational interventions in the study may help explain the lower level of concerns here relative to other Thai studies.

Abstract
The past 2 decades have taught us that HIV prevention can work. We now have evidence from places as diverse as Senegal, Thailand, Uganda, and Australia that concerted HIV prevention efforts at the national level have resulted in the maintenance of low seroprevalence rates where they otherwise would have been expected to rise. We are beginning to observe declining rates of HIV prevalence and incidence in places and populations with historically high rates--for example, injection drug users in New York City. This trend points to the long-term impact of prevention efforts in those communities. The best of these efforts have been based on sound scientific research. As we move into the third decade of the AIDS epidemic, it is important to restate principles, acknowledge advances, and identify challenges and future directions in HIV prevention research.

Abstract
BACKGROUND In Latin America, motels rent rooms for commercial and non-commercial sex. We investigated the impact of providing health-education material and condoms on condom use in Managua, Nicaragua. METHODS In a randomised controlled trial, in 19 motels, we gave condoms on request, made them available in rooms, or gave condoms directly to couples, with and without the presence of health-education material in the rooms. In a factorial design we assessed condom use directly by searching the rooms after couples had left. FINDINGS 11 motels were used mainly by sex workers and their clients and eight mainly for non-commercial sex. 6463 couples attended the motels in 24 days. On 3106 (48.0%) occasions, at least one used condom was retrieved. Condom use was more frequent for commercial sex than for non-commercial sex (60.5 vs 20.2%). The presence of health-education material lowered the frequency of condom use for commercial sex (odds ratio 0.89 [95% CI 0.84-0.94]) and had no effect on use for non-commercial sex (1.03 [0.97-1.08]). Condom use increased for commercial (1.31 [1.09-1.75]) and non-commercial sex (1.81 (1.14-2.81) if condoms were available in rooms. Directly handing condoms to couples was similarly effective for commercial sex but less effective for non-commercial sex (1.32 [1.03-1.61] vs 1.52 [1.01-2.38]). INTERPRETATION In Latin America, motels are key locations for promoting the use of condoms. Making condoms available in rooms is the most effective strategy to increase condom use, whereas use of health-education material was ineffective. These findings have important implications for HIV-prevention policies.
