The Amazon Hope: A qualitative and quantitative assessment of a mobile clinic ship in the Peruvian Amazon.

The Loreto region of the Peruvian Amazon faces many obstacles to health care delivery. The majority of the population is river-bound and lives below the poverty line, with some of the worst health indicators in Peru. To overcome these barriers and fill a gap in health services, an NGO-based provider known as the Vine Trust has been providing care since 2001 via a mobile ship clinic called the Amazon Hope. This study presents an assessment of the Amazon Hope, first reporting health indicators of the program´s catchment area, services provided, and program utilization. It then describes perceptions of the program by community members and health workers, the program's strengths and weaknesses in contributing to health service delivery, and provides recommendations addressing limitations. The qualitative analysis included 20 key informant interviews with community members and health service providers. In the quantitative analysis, 4,949 residents of the catchment area were surveyed about medical histories, experiences with the program, and suggestions for improvement. The survey showed poor indicators for reproductive health. The AH clinic was the main provider of health care among those surveyed. Community members reported satisfaction with the program's quality of care, and health workers felt the program provided a unique and necessary service. However, community members requested prior notification and additional services, while health workers described misunderstandings in community-tailored care, and difficulties with continuity of care and coordination. Data show that the program has been successful in providing quality health care to a population but has room to improve in its health service delivery. Suggested improvements are provided based on participant suggestions and relevant literature. The study sheds light on the important role of mobile clinics in Peru, and the methodology can serve as a model for assessing the role of mobile clinics in other remote settings.

HPV Prevalence in Multiple Anatomical Sites among Men Who Have Sex with Men in Peru.

BACKGROUND: Human Papilloma Virus (HPV) infection is the most common sexually transmitted viral infection worldwide. HPV is highly prevalent in sexually active men who have sex with men (MSM) and has been associated with anal cancer, penile cancer, and oropharyngeal cancer. METHODS: From March to September 2011, we conducted a cross-sectional study of HPV prevalence among MSM above age 18 years. Participants were recruited using respondent driven sampling at Clinica Cayetano Heredia. All participants provided anal, genital, and oral samples for HPV DNA testing, and blood for HIV and HPV antibody testing. RESULTS: A total of 200 MSM were recruited in the study. The mean age was 34 years (range 18-59 years, SD = 9.4) and101 participants were HIV negative (99 HIV positive). HPV 6/11/16/18 or quadrivalent HPV vaccine (HPV4) genotype seroprevalence among HIV negative and positive MSM was 64.3% (55%-75.9%) and 93.8% (87.6%-99.2%) respectively (p<0.001). HIV positivity was associated with a higher prevalence of HPV4 and HPV 16/18 DNA at external genital sites and the anal canal. HPV4 DNA prevalence at external genital sites among HIV negative and positive MSM was 14.9% and 28.7% (p = 0.02) respectively, at anal canal was 50.9% and 79.0% (p = 0.001), and at the oral cavity was 9.9% and 8.5% (p = 0.6). CONCLUSIONS: HPV4 seroprevalence was high in our study among both HIV positives and negatives, with HPV DNA prevalence much lower, and the anal canal being the anatomical site with the highest HPV DNA prevalence. HPV prevention interventions are needed among MSM at high-risk for HIV infection.

High prevalence of human T-lymphotropic virus infection in indigenous women from the peruvian Amazon.

BACKGROUND: In an earlier study, we detected an association between human T-cell lymphotropic virus (HTLV) infection and cervical human papillomavirus (HPV) in indigenous Amazonian Peruvian women of the Shipibo-Konibo ethnic group. As both HTLV and HPV can be transmitted sexually, we now report a population-based study examining the prevalence and risk factors for HTLV-1 and HTLV-2 infection in this population. METHODS: Between July and December 2010, we conducted a comprehensive screening for HTLV among Shipibo-Konibo women 15 to 39 years of age living in two communities located in Lima and in 17 communities located within four hours by car or boat from the Amazonian city of Pucallpa in Peru. RESULTS: We screened 1,253 Shipibo-Konibo women for HTLV infection 74 (5.9%) tested positive for HTLV-1, 47 (3.8%) for HTLV-2 infection, and 4 (0.3%) had indeterminate results. In the multivariate analysis, factors associated with HTLV-1 infection included: older age (Prevalence Ratio (PR): 1.04, 95% CI 1.00-1.08), primary education or less (PR: 2.01, 95% CI: 1.25-3.24), younger or same age most recent sex partner (PR: 1.66, 95% CI: 1.00-2.74), and having a most recent sex partner who worked at a logging camp (PR: 1.73, 95% CI: 1.09-2.75). The only factor associated with HTLV-2 infection was older age (PR: 1.08, 95% CI: 1.03-1.12). CONCLUSION: HTLV infection is endemic among Shipibo-Konibo women. Two characteristics of the sexual partner (younger age and labor history) were associated with infection in women. These results suggest the need for implementation of both HTLV screening during the antenatal healthcare visits of Shipibo-Konibo women, and counseling about the risk of HTLV transmission through prolonged breastfeeding in infected women. We also recommend the implementation of prevention programs to reduce sexual transmission of these viruses.

Structural factors that increase HIV/STI vulnerability among indigenous people in the Peruvian amazon.

We examined structural factors-social, political, economic, and environmental-that increase vulnerability to HIV among indigenous people in the Peruvian Amazon. Indigenous adults belonging to 12 different ethnic groups were purposively recruited in four Amazonian river ports and 16 indigenous villages. Qualitative data revealed a complex set of structural factors that give rise to environments of risk where health is constantly challenged. Ferryboats that cross Amazonian rivers are settings where unprotected sex-including transactional sex between passengers and boat crew and commercial sex work-often take place. Population mobility and mixing also occurs in settings like the river docks, mining sites, and other resource extraction camps, where heavy drinking and unprotected sex work are common. Multilevel, combination prevention strategies that integrate empirically based interventions with indigenous knowledge are urgently needed, not only to reduce vulnerability to HIV transmission, but also to eliminate the structural determinants of indigenous people's health.

Short Text Messages to Motivate HIV Testing Among Men Who have Sex with Men: A Qualitative Study in Lima, Peru.

OBJECTIVE: The objective of this study is to identify features and content that short message service (SMS) should have in order to motivate HIV testing among men who have sex with men (MSM) in Lima, Peru. METHODS: From October, 2010 to February, 2011, we conducted focus groups at two stages; six focus groups were conducted to explore and identify SMS content and features and two additional focus groups were conducted to tailor SMS content. The text messages were elaborated within the theoretical framework of the Information-Motivation-Behavioral Skills model and the Social Support Theory. RESULTS: A total of 62 individuals participated in the focus groups. The mean age of participants was 28 years (range 18-39). We identified important features and content items needed for the successful delivery of text messages, including: a) the use of neutral and coded language; b) appropriate frequency and time of delivery; c) avoiding mass and repetitive messages; and d) use of short, concise and creative messages. Although in Peru receiving text messages is usually a free service, it is important to remind participants that receiving messages will be free of charge. CONCLUSION: Text messages can be used to promote HIV testing among Peruvian MSM. It is important to consider adequate frequency, message content and cost when delivering messages to promote HIV testing in this population.

Motivating men who have sex with men to get tested for HIV through the internet and mobile phones: a qualitative study.

BACKGROUND: Men who have sex with men (MSM) have the highest HIV prevalence in Peru, yet they are underserved by traditional preventive programs. In Peru, the Internet and mobile phones have emerged as an effective and convenient tool to reach this population. METHODS AND FINDINGS: From October 2010 to February 2011, we conducted eight focus groups with gay identified MSM (closeted and out-of-the-closet) and with self-identified heterosexual MSM in order to identify key features and preferences to be used to tailor culturally-appropriate messages that could be delivered through Internet and mobile phones to motivate MSM to get tested for HIV. Participants reported that in order to motivate HIV testing among MSM, interventions need to be based on motivational messages that encourage participants to overcome the fear of getting tested. Messages should increase the HIV risk perception (of participants who do not consider themselves at risk) by eliciting risky situations experienced by MSM. Messages should emphasize confidentiality, respect and the professionalism of the personnel conducting the counseling and testing. A thorough explanation of the process of HIV testing and the steps to follow after receiving the results should be provided. Messages should also contain information about the venue where the test will be conducted in terms of client characteristics, location, hours of operation and personnel. Finally, stigmatizing and stereotyping messages or images about "being gay" should not be included, as they act as deterrents for getting tested. CONCLUSIONS: Interventions aimed at motivating HIV testing among MSM should include motivational messages that reduce the fear of getting tested and increase the risk perception of participants. They should also market the venue where the testing will be conducted, the professionals who will perform the tests, and the type of tests available. Stigmatizing messages or images should be avoided.

HTLV-1 and -2 infections among 10 indigenous groups in the Peruvian Amazon.

Infections with HTLV-1 and -2 were detected in 12 (1.9%) and 6 (0.9%) indigenous individuals living in 27 Amazonian villages in Peru. All infections occurred in Shipibo-Konibo people. HTLV was more common among participants living in villages distant from larger port cities and women with non-monogamous sexual partners.

Association between human papillomavirus and human T-lymphotropic virus in indigenous women from the Peruvian Amazon.

BACKGROUND: No association between the Human T-cell lymphotropic virus (HTLV), an oncogenic virus that alters host immunity, and the Human Papillomavirus (HPV) has previously been reported. Examining the association between these two viruses may permit the identification of a population at increased risk for developing cervical cancer. METHODS AND FINDINGS: Between July 2010 and February 2011, we conducted a cross-sectional study among indigenous Amazonian Peruvian women from the Shipibo-Konibo ethnic group, a group with endemic HTLV infection. We recruited women between 15 and 39 years of age who were living in the cities of Lima and Ucayali. Our objectives were to determine the association between HTLV and: (i) HPV infection of any type, and (ii) high-risk HPV type infection. Sexually active Shipibo-Konibo women were screened for HTLV-1 and HTLV-2 infections. All HTLV-1 or -2 positive women, along with two community-matched HTLV negative sexually active Shipibo-Konibo controls were later tested for the presence of HPV DNA, conventional cytology, and HIV. We screened 1,253 Shipibo-Konibo women, observing a prevalence of 5.9% (n = 74) for HTLV-1 and 3.8% (n = 47) for HTLV-2 infections. We enrolled 62 (60.8%) HTLV-1 positive women, 40 (39.2%) HTLV-2 positive women, and 205 community-matched HTLV negative controls. HTLV-1 infection was strongly associated with HPV infection of any type (43.6% vs. 29.3%; Prevalence Ratio (PR): 2.10, 95% CI: 1.53-2.87), and with high-risk HPV infection (32.3% vs. 22.4%; PR: 1.93, 95% CI: 1.04-3.59). HTLV-2 was not significantly associated with either of these HPV infections. CONCLUSIONS: HTLV-1 infection was associated with HPV infection of any type and with high-risk HPV infection. Future longitudinal studies are needed to evaluate the incidence of high-risk HPV infection as well as the incidence of cervical neoplasia among HTLV-1 positive women.

Risk behaviors and reasons for not getting tested for HIV among men who have sex with men: an online survey in Peru.

BACKGROUND: Men who have sex with men (MSM) account for the greatest burden of the HIV epidemic in Peru. Given that MSM are frequent users of the Internet, understanding the risk behaviors and the reasons for not getting tested among MSM who surf the Internet may improve the tailoring of future online behavioral interventions. METHODS: From October 2007 to April 2008, we conducted an online survey among users of seven Peruvian gay websites. RESULTS: We received 1,481 surveys, 1,301 of which were included in the analysis. The median age of the participants was 22.5 years (range 12-71), 67% were homosexual, and the remainder was bisexual. Of survey respondents, 49.4% had never been tested for HIV and only 11.3% were contacted in-person during the last year by peer health educators from the Peruvian Ministry of Health and NGOs. Additionally, 50.8% had unprotected anal or vaginal sex at last intercourse, and a significant percentage reported a condom broken (22.1%), slipped (16.4%) or sexual intercourse initiated without wearing a condom (39.1%). The most common reasons for not getting tested for HIV among high-risk MSM were "I fear the consequences of a positive test result" (n = 55, 34.4%), and "I don't know where I can get tested" (n = 50, 31.3%). CONCLUSIONS: A small percentage of Peruvian MSM who answered our online survey, were reached by traditional peer-based education programs. Given that among high-risk MSM, fear of a positive test result and lack of awareness of places where to get tested are the most important reasons for not taking an HIV test, Internet interventions aimed at motivating HIV testing should work to reduce fear of testing and increase awareness of places that offer free HIV testing services to MSM.

Effect of an online video-based intervention to increase HIV testing in men who have sex with men in Peru.

BACKGROUND: Although many men who have sex with men (MSM) in Peru are unaware of their HIV status, they are frequent users of the Internet, and can be approached by that medium for promotion of HIV testing. METHODS: We conducted an online randomized controlled trial to compare the effect of HIV-testing motivational videos versus standard public health text, both offered through a gay website. The videos were customized for two audiences based on self-identification: either gay or non-gay men. The outcomes evaluated were 'intention to get tested' and 'HIV testing at the clinic.' FINDINGS: In the non-gay identified group, 97 men were randomly assigned to the video-based intervention and 90 to the text-based intervention. Non-gay identified participants randomized to the video-based intervention were more likely to report their intention of getting tested for HIV within the next 30 days (62.5% vs. 15.4%, Relative Risk (RR): 2.77, 95% Confidence Interval (CI): 1.42-5.39). After a mean of 125.5 days of observation (range 42-209 days), 11 participants randomized to the video and none of the participants randomized to text attended our clinic requesting HIV testing (p = 0.001). In the gay-identified group, 142 men were randomized to the video-based intervention and 130 to the text-based intervention. Gay-identified participants randomized to the video were more likely to report intentions of getting an HIV test within 30 days, although not significantly (50% vs. 21.6%, RR: 1.54, 95% CI: 0.74-3.20). At the end of follow up, 8 participants who watched the video and 10 who read the text visited our clinic for HIV testing (Hazard Ratio: 1.07, 95% CI: 0.40-2.85). CONCLUSION: This study provides some evidence of the efficacy of a video-based online intervention in improving HIV testing among non-gay-identified MSM in Peru. This intervention may be adopted by institutions with websites oriented to motivate HIV testing among similar MSM populations. TRIAL REGISTRATION: Clinicaltrials.gov NCT00751192.

Riesgos y beneficios del uso de Internet entre personas viviendo con VIH/SIDA en Lima, Perú / Risks and benefits of Internet use among people living with HIV/AIDS in Lima, Peru

Objetivo: Evaluar el uso de Internet para buscar parejas sexuales e información sobre VIH/SIDA o infecciones de transmisión sexual (ITS) entre personas viviendo con VIH/SIDA (PVVS). Materiales y métodos: Entrevistamos a las PVVS que acudieron consecutivamente a Vía Libre en Lima Perú entre mayo y junio de 2004. Resultados: De las 100 PVVS (46 hombres que tienen sexo con hombres [HSH], 18 hombres heterosexuales y 36 mujeres), 59 por ciento reportó el uso de Internet en los últimos 12 meses. De ellos, la mayoría (73 por ciento) accedió a Internet en un lugar público; 16 (27,1 por ciento) reportaron haber buscado parejas sexuales en línea y cinco (8,5 por ciento) reportaron haber tenido sexo con una pareja que conocieron por Internet. Todas las PVVS que buscaron sexo en Internet fueron hombres, siendo el porcentaje de HSH significativamente mayor que la de heterosexuales (94 por ciento frente a 6 por ciento; p=0,032). Los cinco que reportaron haber tenido sexo con una pareja que conocieron en línea fueron HSH. De los que accedieron a Internet en el último año, 76 por ciento (45/59) lo hizo para buscar información sobre VIH/SIDA y 39 por ciento (23/59) para buscar información sobre otras ITS. Conclusiones: Entre las PVVS encuestadas, más de la mitad reportó acceso a Internet. La mayoría lo hizo para buscar información sobre VIH/SIDA y más de la cuarta parte - casi exclusivamente HSH - lo hizo para buscar parejas sexuales. Estos hallazgos sugieren que Internet es una herramienta conveniente para brindar mensajes de prevención en línea sobre VIH/ITS a HSH de alto riesgo.

Objective: To evaluate use of the Internet for seeking sex partners and information on HIV and/or sexually transmitted infections (STIs) among people living with HIV/AIDS (PLWHA). Materials and methods: We interviewed consecutive PLWHA attending at Vía Libre, in Lima, Peru, between May and June 2004. Results: Of 100 PLWHA, (46 men who had sex with men [MSM], 18 heterosexual men and 36 women), 59 per cent reported using the Internet in the last 12 months. Of these, the majority (73 per cent) accessed the Internet at a public place; 16 (27,1 per cent) reported having gone online to search for sexual partners; and five (8,5 per cent) reported having had sex with a partner found over the Internet. All sex seekers were men, of them a greater percentage were MSM rather than heterosexual (94 per cent vs. 6 per cent, p= 0,032). All five respondents who reported having had sex with a partner found online were MSM. Of those who accessed the Internet in the past year, 76 per cent (47/59) had used it to find information on HIV/AIDS, and 39 per cent (23/59) had used it to seek information on other STIs. Conclusions: Among PLWHA interviewed more than half reported Internet access. More than a quarter -almost exclusively MSM- had used it to search for sex partners, however, the majority had used the Internet to look for information about HIV/AIDS. These findings suggest that the Internet offers a convenient tool to engage high-risk MSM in online HIV/STI prevention.
