Implementation and evaluation of an HIV/STD intervention in Peru

Study protocol for a hybrid implementation-effectiveness trial of Game Changers for Cervical Cancer Prevention in Uganda

INTRODUCTION

Cervical cancer (CC) is the leading cause of cancer-related deaths among Uganda women, yet rates of CC screening are very low. Training women who have recently screened to engage in advocacy for screening among women in their social network is a network-based strategy for promoting information dissemination and CC screening uptake.

METHODS

Drawing on the Exploration, Preparation, Implementation and Sustainment (EPIS) framework for implementation science, this hybrid type 1 randomized controlled trial (RCT) of a peer-led, group advocacy training intervention, Game Changers for Cervical Cancer Prevention (GC-CCP), will examine efficacy for increasing CC screening uptake as well as how it can be implemented and sustained in diverse clinic settings. In the Preparation phase we will prepare the four study clinics for implementation of GC-CCP and the expected increase in demand for CC screening, by using qualitative methods (stakeholder interviews and client focus groups) to identify and address structural barriers to easy access to CC screening. In the Implementation phase, GC-CCP will be implemented over 36 months at each clinic, with screened women (index participants) enrolled as research participants receiving the intervention in the first 6 months as part of a parallel group RCT overseen by the research study team to evaluate efficacy for CC screening uptake among their enrolled social network members. All research participants will be assessed at baseline and months 6 and 12. Intervention implementation and supervision will then be transitioned to clinic staff and offered as part of usual care in the subsequent 30 months as part of the Sustainability phase. Using the RE-AIM framework, we will evaluate engagement in GC-CCP and CC advocacy (reach), alter CC screening (effectiveness), adoption into clinic operations, implementation outcomes (acceptability, feasibility, fidelity, cost-effectiveness) and maintenance.

DISCUSSION

This is one of the first studies to use a network-driven approach and empowerment of CC screened peers as change agents to increase CC screening. If shown to be an effective and sustainable implementation strategy for promoting CC screening, this peer advocacy model could be applied to other preventative health behaviors and disease contexts.

Seeking information and services associated with reproductive health among rural Peruvian young adults: exploratory qualitative research from Amazonas, Peru

BACKGROUND

Sexual and reproductive health (SRH) literacy allows young adults to make informed decisions about health outcomes. In Peru, roughly one fifth of the population lives in rural areas, and little is known about where young adults in rural areas get their SRH information. The aim of this study was to identify what motivates and influences young adults to seek information and care related to SRH in three rural communities in the highlands of Northern Peru.

METHODS

Five gender-stratified focus group discussions with a total of 24 participants, and nine follow-up interviews were conducted to generate in-depth narrative data and triangulate data from the target group. Participants were women and men aged 18-24. The focus group discussions and interviews explored sources of reproductive health information, the role of informal social networks, barriers to care, and primary health concerns of the target population.

RESULTS

Main findings include: (1) The two greatest perceived SRH risks were unwanted pregnancy and abnormal discharge; (2) There appears to be limited concern about HIV or other sexually transmitted infections in the narratives; (3) There is a low quality of information concerning SRH, with discrepancies between the genders; (4) A broad spectrum of sources for SRH information were cited, including Internet, traditional healers, and specialized care; and varied by gender and life experience; (5) Having trust in the information source was the primary variable associated with uptake of services and/or access to information for both men and women. However, men reported more embarrassment around seeking services and information, whereas women faced more physical barriers.

CONCLUSIONS

There is a lack of SRH information among young adults in some communities in the northern highlands of Peru. Both schools and health centers were noted as being trusted and established information sources for all genders so could be a key resource to explore as a way to disseminate information.

Social network-based group intervention to promote uptake of cervical cancer screening in Uganda: study protocol for a pilot randomized controlled trial

INTRODUCTION

Cervical cancer (CC) is the most common cancer and accounts for one quarter of all cancer-related deaths among women in Uganda, where lifetime CC screening is estimated to be as low as 5%. This study will evaluate the feasibility, acceptability, and preliminary efficacy of a social network-based group intervention designed to empower women who have received CC screening to encourage women in their social network to also screen.

METHODS

Forty adult women (index participants) who have recently screened for CC will be recruited, 20 of whom will be randomly assigned to take part in the intervention and 20 to the wait-list control. Each index participant will be asked to recruit up to three female social network members (i.e., alters; maximum total = 120 alters) who have not screened for CC to participate in the study. Assessments (survey and chart abstraction) will be administered at baseline and month 6 to index and alter participants. The primary outcome is CC screening among participating alters, with a secondary outcome being engagement in CC prevention advocacy among index participants. Repeated-measure multivariable regression analyses will be conducted to compare outcomes between the intervention and control arms.

DISCUSSION

If successful, this intervention model has the potential not only to impact uptake of CC screening and treatment but also to establish a paradigm that can be applied to other health conditions.

A Peer-Led Online Community to Increase HIV Self-Testing Among African American and Latinx MSM: A Randomized Controlled Trial

OBJECTIVE

We sought to assess the effectiveness of using a peer-led online community to increase HIV self-testing among Latinx and African American men who have sex with men (MSM).

DESIGN

Randomized controlled trial.

METHODS

Throughout 6 waves, between February 18, 2017, and January 8, 2021, 900 HIV negative and/or serostatus unknown Los Angeles-based MSM (68.9% Latinx, 16.0% African American, and 7.4% White) participated in an online 12-week HIV prevention randomized controlled trial. A total of 79 trained role models (peer leaders) were randomly assigned to participants within clusters to build trust and deliver HIV testing information on Facebook groups. Participants in control groups were assigned to groups without peer leaders. Participants were not required to respond to peer leaders or to remain group members. Participants completed self-report assessments at baseline and 12-week follow-up and could receive a free HIV self-testing kit during the study period.

RESULTS

Compared with control group participants, intervention group participants were significantly more likely to accept the offer for the HIV self-testing kit (intervention 130 of 450, 29%; control 102 of 450, 22.7%; odds ratio = 1.43, 95% confidence interval: 1.04 to 1.95, P = 0.03), report having taken an HIV self-test within the past 3 months (odds ratio = 1.47, 95% confidence interval: 1.01 to 2.13, P = 0.04), and report drinking fewer glasses of alcohol in an average week (P = 0.01). Effects seemed concentrated within later study waves. Study retention was greater than 93%.

CONCLUSIONS

A peer-led online community seems to be an effective method of increasing HIV self-testing among MSM of color. We discuss the implications of the wave effects on public health research and policy.

Social network-based group intervention to promote HIV prevention in Uganda: study protocol for a cluster randomized controlled trial of Game Changers

INTRODUCTION

Innovative strategies are needed to disseminate HIV prevention messages across communities efficiently, as well as reduce HIV stigma while promoting HIV prevention. This randomized controlled trial will evaluate the efficacy of a social network-based group intervention, Game Changers, which trains persons living with HIV (PLWH) to encourage members of their social network to use HIV protective behaviors METHODS: PLWH in HIV care for at least 1 year will be randomly assigned to receive the 8-session group advocacy training intervention or no-intervention control group. Each enrolled PLWH (index participant) will be asked to recruit up to four social network members (alter participant). Assessments will be administered at baseline and months 6, 12, and 18 to both index and alter participants. The primary outcomes are HIV testing and condom use among alter participants; secondary outcomes are engagement in HIV prevention advocacy and internalized HIV stigma among index participants. Repeated-measures multivariable regression analyses will be conducted to compare outcomes between the intervention and control arms, in addition to a cost-effectiveness evaluation.

DISCUSSION

This social network-based approach to HIV prevention is particularly timely in the era of biomedical interventions, which require widespread penetration of effective HIV prevention and care messaging into communities. Positioning PLWH as central to the solution for controlling (vs. causing) the HIV epidemic has the potential to reduce HIV stigma and improve prevention outcomes at the individual and network levels.

A Pilot Test of Game Changers, a Social Network Intervention to Empower People with HIV to be Prevention Advocates in Uganda

We conducted a pilot randomized controlled trial of Game Changers, a 6-session group intervention that empowers people with HIV to be HIV prevention advocates in their social networks. Ninety-nine people with HIV (51 intervention, 48 wait-list control) and 58 of their social network members (alters) completed baseline and 5- and 8-month post-baseline assessments. Results indicated high acceptability, demonstrated by participants' and facilitators' positive attitudes qualitatively and favorable ratings of intervention sessions quantitatively, and high feasibility (76% attended all intervention sessions). Intention-to-treat analyses indicated significantly increased HIV prevention advocacy among HIV-positive participants and alters [b (SE) = 0.4 (0.2), p = .017; b (SE) = 0.4 (0.2), p = .035]; reduced internalized HIV stigma [b (SE) =  - 0.3 (0.1), p = .012], increased HIV-serostatus disclosure [b (SE) = 0.1 (0.1), p = .051], and increased social network density among HIV-positive participants [b (SE) = 0.1 (0.03), p = .004]; and marginally reduced condomless sex among alters [OR (95% CI) = 0.3 (0.1-1.2), p = .08]. Positioning people with HIV as central to prevention has the potential to reduce stigma and improve prevention outcomes throughout social networks.

Explaining the Education-Health Gradient in Preventing STIs in Andean Peru: Cognitive Executive Functioning, Awareness and Health Knowledge

CONTEXT

Little is known about the pathways mediating the relationship between education and health. It is widely assumed that formal schooling leads to awareness of health risks (e.g., STIs) and, in turn, to adoption of preventive behavior (e.g., condom use); however, evidence supporting this mechanism has been limited.

METHODS

Survey data were collected in 2010 from a sample of 247 adults aged 30-62 living in an isolated Andean district of Peru; these individuals had widely varying exposure to schooling, and their community had recently experienced elevated risks of STIs. Structural equation modeling was used to estimate the degree to which schooling is associated with cognitive resources, STI awareness and sexual health knowledge, and how these jointly are associated with ever-use of condoms.

RESULTS

Thirty-two percent of respondents reported ever-use of condoms. One additional year of schooling was associated with a 2.7-percentage-point increase in the probability of condom use, after adjustment for covariates. The pathway between education and condom use was mediated by cognitive executive functioning (CEF) skills (0.26 standard deviations), STI awareness (0.09) and sexual health knowledge (0.10); CEF skills were associated with condom use both directly and indirectly, through STI awareness and sexual health knowledge, and accounted for two-thirds of the education-condom use gradient.

CONCLUSIONS

The relationship between education and STI prevention may be more complex than is often assumed and is mediated by CEF skills, STI awareness and sexual health knowledge. Studies should examine whether STI prevention interventions are more effective if they enhance cognitive skills used to translate information into protective behaviors.

Using opinion leaders to address intervention gaps in concussion prevention in youth sports: key concepts and foundational theory

Behavioral interventions to increase disclosure and proper management of concussion in youth sports have unrealized potential when it comes to preventing concussion. Interventions have focused on changing individual athlete behavior and have fallen short of the potential for sustained systemic behavioral change. One potentially critical reason for this shortfall is that other key determinants of risk behaviors at all levels of the socio-ecological model (e.g. interpersonal, community, policy) are not addressed in extant programming. There is a critical need for theory-driven interventions that address concussion prevention and education at the community level and target sustainable culture change. The Popular Opinion Leader (POL) intervention, a multi-level intervention model previously successfully employed in multiple public health contexts, is theoretically well positioned to affect such change. POL is based on the Diffusion of Innovations framework and involves identifying, recruiting, and training well-respected and trusted individuals to personally endorse prevention and risk-reduction within their social networks. Critical behavioral changes related to concussion disclosure and management have been shown to diffuse to others if enough opinion leaders endorse and support the behaviors. This article summarizes the concepts and principles of POL and describes how it could be adapted for and implemented in youth sport settings. For optimal impact, POL needs to adapt to several factors unique to youth sports settings and culture. First, adult involvement may be important, given their direct involvement in the athlete's medical care. However, parents and coaches' opinions on injury care-seeking, competition, and safety may affect their perceptions of POL. Second, youth sports are structured settings both physically and socioculturally. Games and practices may provide opportunities for the informal interactions that are critical to the success of POL. However, youth sport setting membership is transient as players get older and move to other sport settings; POL approaches need to be self-sustaining despite this turnover. Moreover, stakeholder value placed on athlete development and competition, alongside safety, must be considered. Formative research is needed to ensure that POL principles are translated into the youth sport setting while maintaining fidelity to the concepts and principles that have made POL successful for other health outcomes.

The HOPE social media intervention for global HIV prevention in Peru: a cluster randomised controlled trial

BACKGROUND

Social media technologies offer new approaches to HIV prevention and promotion of testing. We examined the efficacy of the Harnessing Online Peer Education (HOPE) social media intervention to increase HIV testing among men who have sex with men (MSM) in Peru.

METHODS

In this cluster randomised controlled trial, Peruvian MSM from Greater Lima (including Callao) who had sex with a man in the past 12 months, were 18 years of age or older, were HIV negative or serostatus unknown, and had a Facebook account or were willing to create one (N=556) were randomly assigned (1:1) by concealed allocation to join intervention or control groups on Facebook for 12 weeks. For the intervention, Peruvian MSM were trained and assigned to be HIV prevention mentors (peer-leaders) to participants in Facebook groups. The interventions period lasted 12 weeks. Participants in control groups received an enhanced standard of care, including standard offline HIV prevention available in Peru and participation in Facebook groups (without peer leaders) that provided study updates and HIV testing information. After accepting a request to join the groups, continued participation was voluntary. Participants also completed questionnaires on HIV risk behaviours and social media use at baseline and 12 week follow-up. The primary outcome was the number of participants who received a free HIV test at a local community clinic. The facebook groups were analysed as clusters to account for intracluster correlations. This trial is registered with ClinicalTrials.gov, number NCT01701206.

FINDINGS

Of 49 peer-leaders recruited, 34 completed training and were assigned at random to the intervention Facebook groups. Between March 19, 2012, and June 11, 2012, and Sept 26, 2012, and Dec 19, 2012, 556 participants were randomly assigned to intervention groups (N=278) or control groups (N=278); we analyse data for 252 and 246. 43 participants (17%) in the intervention group and 16 (7%) in the control groups got tested for HIV (adjusted odds ratio 2·61, 95% CI 1·55–4·38). No adverse events were reported.

INTERPRETATION

Development of peer-mentored social media communities seemed to be an efficacious method to increase HIV testing among high-risk populations in Peru. Results suggest that the HOPE social media intervention could improve HIV testing rates among MSM in Peru.

Association of Internalized and Social Network Level HIV Stigma With High-Risk Condomless Sex Among HIV-Positive African American Men

We examined whether internalized HIV stigma and perceived HIV stigma from social network members (alters), including the most popular and most similar alter, predicted condomless intercourse with negative or unknown HIV status partners among 125 African American HIV-positive men. In a prospective, observational study, participants were administered surveys at baseline and months 6 and 12, with measures including sexual behavior, internalized HIV stigma, and an egocentric social network assessment that included several measures of perceived HIV stigma among alters. In longitudinal multivariable models comparing the relative predictive value of internalized stigma versus various measures of alter stigma, significant predictors of having had condomless intercourse included greater internalized HIV stigma (in all models), the perception that a popular (well-connected) alter or alter most like the participant agrees with an HIV stigma belief, and the interaction of network density with having any alter that agrees with a stigma belief. The interaction indicated that the protective effect of greater density (connectedness between alters) in terms of reduced risk behavior dissipated in the presence of perceived alter stigma. These findings call for interventions that help people living with HIV to cope with their diagnosis and reduce stigma, and inform the targets of social network-based and peer-driven HIV prevention interventions.

HIV Prevalence and Awareness of Positive Serostatus Among Men Who Have Sex With Men and Transgender Women in Bogotá, Colombia

OBJECTIVES

We estimated HIV prevalence among men who have sex with men (MSM) and transgender women in Bogotá, Colombia, and explored differences between HIV-positive individuals who are aware and unaware of their serostatus.

METHODS

In this cross-sectional 2011 study, we used respondent-driven sampling (RDS) to recruit 1000 MSM and transgender women, who completed a computerized questionnaire and received an HIV test.

RESULTS

The RDS-adjusted prevalence was 12.1% (95% confidence interval [CI] = 8.7, 15.8), comparable to a previous RDS-derived estimate. Among HIV-positive participants, 39.7% (95% CI = 25.0, 54.8) were aware of their serostatus and 60.3% (95% CI = 45.2, 75.5) were unaware before this study. HIV-positive-unaware individuals were more likely to report inadequate insurance coverage, exchange sex (i.e., sexual intercourse in exchange for money, goods, or services), and substance use than other participants. HIV-positive-aware participants were least likely to have had condomless anal intercourse in the previous 3 months. Regardless of awareness, HIV-positive participants reported more violence and forced relocation experiences than HIV-negative participants.

CONCLUSIONS

There is an urgent need to increase HIV detection among MSM and transgender women in Bogotá. HIV-positive-unaware group characteristics suggest an important role for structural, social, and individual interventions.

Engagement in HIV Prevention Advocacy Associated with Increased Consistent Condom Use Among HIV Clients in Uganda

We examined whether engagement in prevention advocacy among HIV clients is associated with their own condom use and HIV care adherence. Longitudinal data merged from three studies in Uganda produced a sample of 1,882 participants who were administered assessments at baseline and months 6 and 12. The measure of prevention advocacy was the mean of two Likert scale items assessing encouragement of others to (1) use condoms, and (2) get HIV tested. In regression analyses controlling for demographics and known correlates of the dependent variables, increased prevention advocacy from baseline to month 12 was significantly associated with increased consistent condom use and marginally associated with increased antiretroviral adherence and clinic attendance. These results suggest that empowering HIV clients to engage in prevention advocacy with others may benefit their own HIV protective behaviors and should be promoted as a component to interventions targeting positive living among people living with HIV.

Feasibility of Recruiting Peer Educators to Promote HIV Testing Using Facebook Among Men Who have Sex with Men in Peru

A peer leader-based intervention using social media can be an effective means to encourage Peruvian gay men to test for HIV. The objective was to explore the feasibility of recruiting and training leaders to deliver a peer intervention via Facebook to promote HIV testing. Training consisted of three sessions focused on HIV epidemiology, consequences of stigma associated with HIV, and ways to use Facebook. We performed pre- and post-training evaluations to assess HIV knowledge and comfort using Facebook. We trained 34 peer leaders. At baseline, the majority of peer leaders were already qualified and knowledgeable about HIV prevention and use of social media. We found a significant increase in proportion of peer leaders who were comfortable using social media to discuss about sexual partners and about STIs. It is feasible to recruit peer leaders who are qualified to conduct a social media based HIV prevention intervention in Peru.

Methods for measuring diffusion of a social media-based health intervention

This study evaluated the feasibility of measuring diffusion from a social networking community-level intervention. One year after completion of a randomized controlled HIV prevention trial on Facebook, 112 minority men who have sex with men (MSM) were asked to refer African-American and/or Latino sex partners to complete a survey. Results suggest that, compared to non-referrers, referrers spent more time online, controlling for age, race, education, and condition. Over 60% of referrals reported hearing about the intervention, and over half reported that the referrer talked to them about changing health behaviors. Results provide support and initial feasibility of using social networking for diffusing community-based HIV interventions.

Project HOPE: online social network changes in an HIV prevention randomized controlled trial for African American and Latino men who have sex with men

OBJECTIVES

We examined whether and how an HIV prevention diffusion-based intervention spread throughout participants' online social networks and whether changes in social network ties were associated with increased HIV prevention and testing behaviors.

METHODS

We randomly assigned 112 primarily racial/ethnic minority men who have sex with men (MSM) to receive peer-delivered HIV (intervention) or general health (control) information over 12 weeks through closed Facebook groups. We recorded participants' public Facebook friend networks at baseline (September 2010) and follow-up (February 2011), and assessed whether changes in network growth were associated with changes in health engagement and HIV testing.

RESULTS

Within-group ties increased in both conditions from baseline to follow-up. Among the intervention group, we found a significant positive relation between increased network ties and using social media to discuss sexual behaviors. We found a positive trending relationship between increased network ties and likelihood of HIV testing, follow-up for test results, and participation in online community discussions. No significant differences were seen within control groups.

CONCLUSIONS

Among high-risk MSM, peer-led social media HIV prevention interventions can increase community cohesion. These changes appear to be associated with increased HIV prevention and testing behaviors.

Comparison between peer-led and teacher-led education in tuberculosis prevention in rural middle schools in Chongqing, China

The aim of this study was to investigate the efficacy of tuberculosis (TB) education through a comparison of peer-led and teacher-led methods of education about TB prevention among middle school students in rural Chongqing, China. A preintervention and postintervention questionnaire survey was conducted in 2 different middle school student groups to measure changes in knowledge, attitude, and practice (KAP) status of those students before and after each TB education program. Of 1265 students participating in the preintervention survey, 1176 completed the postintervention survey. KAP scores of both peer-led and teacher-led groups after intervention improved by as much as 2 times compared with before the intervention and those of the control group (P < .01). KAP scores of immediate evaluation were higher than those of long-term evaluation in the teacher-led education group (P < .01). The teacher-led group had a larger improvement than the peer-led group in practice scores (P < .01) in immediate effect evaluation.

A social-media based HIV prevention intervention using peer leaders

This study seeks to investigate qualities of peer leaders in a social media-based peer-led HIV intervention. African American and Latino men who have sex with men (MSM) peer leaders were recruited through online/offline methods. They were required to have experience with health communication and social media. Over 57% of reported using social networking for seeking sex partners within 3 months. Over 53% spent over 3 hours per week online and about 53% of peer leaders had fewer than 200 Facebook friends. Results suggest that peer leaders can be recruited for social media-based health interventions. Qualities of peer leaders are discussed.

Social networking technologies as an emerging tool for HIV prevention: a cluster randomized trial

BACKGROUND

Social networking technologies are an emerging tool for HIV prevention.

OBJECTIVE

To determine whether social networking communities can increase HIV testing among African American and Latino men who have sex with men (MSM).

DESIGN

Randomized, controlled trial with concealed allocation. (ClinicalTrials.gov: NCT01701206).

SETTING

Online.

PATIENTS

112 MSM based in Los Angeles, more than 85% of whom were African American or Latino.

INTERVENTION

Sixteen peer leaders were randomly assigned to deliver information about HIV or general health to participants via Facebook groups over 12 weeks. After participants accepted a request to join the group, participation was voluntary. Group participation and engagement were monitored. Participants could request a free, home-based HIV testing kit and completed questionnaires at baseline and 12-week follow-up.

MEASUREMENTS

Participant acceptance of and engagement in the intervention and social network participation, rates of home-based HIV testing, and sexual risk behaviors.

RESULTS

Almost 95% of intervention participants and 73% of control participants voluntarily communicated using the social platform. Twenty-five of 57 intervention participants (44%) requested home-based HIV testing kits compared with 11 of 55 control participants (20%) (difference, 24 percentage points [95% CI, 8 to 41 percentage points]). Nine of the 25 intervention participants (36%) who requested the test took it and mailed it back compared with 2 of the 11 control participants (18%) who requested the test. Retention at study follow-up was more than 93%.

LIMITATION

Only 2 Facebook communities were included for each group.

CONCLUSION

Social networking communities are acceptable and effective tools to increase home-based HIV testing among at-risk populations.

Online social networking for HIV education and prevention: a mixed-methods analysis

BACKGROUND

The purpose of this study is to use mixed (qualitative/quantitative) methods to determine (1) the feasibility and acceptability of using online social networking to facilitate HIV-related discussions and (2) the relationship between HIV-related online discussions and requests for a home-based HIV testing kit among men who have sex with men.

METHODS

Participants, primarily African American and Latino, were invited to join a "secret" group on the social networking Web site, Facebook. Peer leaders, trained in HIV prevention, posted HIV-related content. Participants were not obligated to respond to discussions or remain within the group. Participant public group conversations were qualitatively and thematically analyzed. Quantitative methods tested associations between qualitative data, participants' demographic information, and likelihood of requesting a home-based HIV testing kit.

RESULTS

Latino and African American participants (n = 57) voluntarily used Facebook to discuss the following HIV-related topics (n = 485 conversations): prevention and testing, knowledge, stigma, and advocacy. Older participants more frequently discussed prevention and testing, stigma, and advocacy, although younger participants more frequently discussed HIV knowledge-related conversations. As the study progressed, the proportion of messages related to prevention and testing and HIV stigma increased. Multivariate analysis showed that participants posting about HIV prevention and testing (compared with those who did not) were significantly more likely to request an HIV testing kit (odds ratio, 11.14; P = 0.001).

CONCLUSIONS

Facebook can serve as an innovative forum to increase both HIV prevention discussions and HIV testing requests among at-risk groups.

Feasibility of recruiting peer educators for an online social networking-based health intervention

OBJECTIVE

This study aims to determine the feasibility of recruiting peer leaders to deliver a community-based health intervention using social media.

METHOD

We recruited sixteen African American and Latino men who have sex with men (MSM) as peer leaders for either an HIV prevention or general health intervention using social media. Inclusion criteria required that peer leaders were African American or Latino MSM health communication experts experienced using social media. To receive certification, peer leaders attended 3 training sessions on using social media for public health. Questionnaires asking about health knowledge and comfort using social media to discuss health-related topics were provided at baseline and post-training to ensure that peer leaders were qualified post-training. Repeated measures ANOVA models and χ2 tests tested for differences in peer leader knowledge and comfort using social media pre- and post-training.

RESULTS

After training, peer leaders were significantly more comfortable using social media to discuss sexual positions. There were no significant differences pre- and post-training on other comfort or knowledge measures, as at baseline, almost all peer leaders were already comfortable using social media.

CONCLUSION

Results suggest that peer leaders can be recruited who are qualified to conduct health interventions without needing additional training. The discussed training plan can further ensure that any unqualified peer leaders will be prepared after training. To our knowledge, this is the first study to suggest that peer leaders can be recruited as peer health educators to communicate using social media.

An exploratory study of HIV-prevention advocacy by persons in HIV care in Uganda

To explore how people living with HIV (PLHIV) and in care encourage others to adopt HIV-protective behaviours, we conducted in-depth interviews with a purposive sample of 40 HIV clinic patients in Kampala, Uganda. Content analysis was used to examine the message content, trigger events, and outcomes of HIV-prevention advocacy events initiated by the HIV clients with members of their social networks. The content themes included encouraging specific behaviours, such as HIV testing and treatment, condom use and non-promiscuity, as well as more general cautionary messages about protecting oneself from HIV infection. Common triggers for bringing up HIV-prevention advocacy information in a discussion or conversation included: wanting to prevent the targeted person from 'falling into the same problems,' wanting to benefit oneself with regard to avoiding re-infection, out of concern that the target would engage in higher-risk behaviour, due to observed changes in the target's health, and to convey information after receiving treatment at the clinic. The participants mostly reported positive or neutral responses to these advocacy events; negative responses were rare. Interventions to empower PLHIV to be agents of change could represent a new frontier for HIV prevention.

Effect of a community popular opinion leader HIV/STI intervention on stigma in urban, coastal Peru

Evaluating interventions that reduce HIV stigma may help to craft effective stigma-reduction programs. This study evaluates the effects of a community popular opinion leader HIV/STI intervention on stigma in urban, coastal Peru. Mixed effects modeling was used to analyze data on 3,049 participants from the Peru site of the NIHM collaborative trial. Analyses looked at differences between the comparison and intervention groups on a stigma index from baseline to 12- and 24-month follow-up. Sub-analyses were conducted on heterosexual-identified men (esquineros), homosexual-identified men (homosexuales), and socially marginalized women (movidas). Compared to participants in the comparison group, intervention participants reported lower levels of stigma at 12- and 24-month follow-up. Similar results were found within esquineros and homosexuales. No significant differences were found within movidas. Findings suggest that interventions designed to normalize HIV prevention behaviors and HIV communication can reduce HIV-related stigma and change community norms.

Evaluating an HIV and AIDS Community Training Partnership Program in five diamond mining communities in South Africa

In 2006, De Beers Consolidated Diamond Mines in South Africa entered into a partnership with the Soul City Institute for Health and Development Communications to implement an HIV and AIDS Community Training Partnership Program (CTPP), initially in five diamond mining areas in three provinces of South Africa. The aim of CTPP was to improve HIV knowledge and to contribute to positive behavior changes in the targeted populations. This paper describes the evaluation of the CTPP, one year after implementation. The evaluation combined qualitative interviews with key informants and trainers and a post-intervention survey of 142 community members. The successes of the CTPP included capacity building of trainers through an innovative training approach and HIV and AIDS knowledge transfer to community trainers and targeted communities in remote mining towns. The Soul City edutainment brand is popular and emerged as a major reason for success. Challenges included insufficient attention paid to contextual factors, resource constraints and the lack of a monitoring and evaluation framework. Independent evaluations are useful to strengthen program implementation. In remote areas and resource constraint settings, partnerships between non-governmental organisations and corporations may be required for successful community HIV and AIDS initiatives.

Process evaluation of the Community Support Connections merger

Community Support Connections (CSC) is the result of the merger of four private not-for-profit community health care agencies. The purpose of this research project was to evaluate the progress of CSC toward its stated goal: improvement of coordination and accessibility of health services. As of this writing, more than one year into the merger, managers, staff and volunteers believe that the goals of serving more clients more completely through case management are being achieved.

Globalized research and "national science": the case of Peru

Issues in the area of international health research are insufficiently discussed in Latin America. We examine the practices of stakeholders such as the state and the academic community regarding research policy processes and funding sources in Peru. Our findings showed that research policy development and evaluation processes are poor in Peru, most of the country's academic research is published in English only, and researchers' access to funding is limited. Given that the relationship between local academic institutions and foreign research centers is key in developing a "national science," there is a clear need to reinforce the state's capacities for management and research oversight and implementation and to encourage the academic community to improve their institutional policies and research frameworks.

A social marketing approach to building a behavioral intervention for congenital cytomegalovirus

Congenital cytomegalovirus (CMV) is the most common congenital infection in the United States, causing permanent disabilities in more than 5,500 children born each year. In the absence of a vaccine, a promising means of prevention is through a behavioral intervention that educates women about CMV and promotes adherence to hygiene guidelines during pregnancy. Although effective behavioral interventions have been identified for other infectious diseases with similar transmission modes, current research has not yet identified an effective intervention for CMV. One way to gather evidence and identify key elements of a successful CMV intervention is through a social marketing approach. This article describes a five-step process for applying social marketing principles to the research and development, implementation, and evaluation of a CMV behavioral intervention.
