A CBPR Partnership Increases HIV Testing Among Men Who Have Sex With Men (MSM): Outcome Findings From a Pilot Test of the CyBER/testing Internet Intervention

The Internet has emerged as an important tool for the delivery of health promotion and disease prevention interventions. Our community-based participatory research (CBPR) partnership developed and piloted CyBER/testing, a culturally congruent intervention designed to promote HIV testing among men who have sex with men (MSM) within existing Internet chat rooms. Using a quasi-experimental, single-group study design, cross-sectional data were collected from chat room participants, known as “chatters,” at pretest (n = 346) and posttest (n = 315). Extant profile data also were collected to describe the demographics of the online population. The intervention significantly increased self-reported HIV testing among chatters overall, increasing rates from 44.5% at pretest to nearly 60% at posttest (p < .001). Furthermore, chatters who reported having both male and female sexual partners had nearly 6 times the odds of reporting HIV testing at posttest. Findings suggest that chat room—based HIV testing intervention may increase testing among MSM who may be difficult to reach in traditional physical spaces.

A pilot intervention utilizing Internet chat rooms to prevent HIV risk behaviors among men who have sex with men.

Objectives. Chat room-based prevention interventions for human immunodeficiency virus (HIV) are being implemented to reduce the risk of HIV exposure, infection, and re-infection among men who have sex with men (MSM). Methods. Our community-based participatory research partnership implemented a chat room-based intervention known as Cyber-Based Education and Referral/Men for Men (CyBER/M4M). We collected both quantitative and qualitative data to describe the characteristics of chat-room participants (“chatters”) and their HIV risks and prevention needs, and to document intervention delivery. Results. Of the 1,851 chatters who participated in the 18-month intervention, 210 completed the online assessment. The mean age was 30 years. Although the majority self-identified as gay, 25.8% self-identified as bisexual. More than half self-identified as white and one-third as black or African American. A total of 8.6% reported being HIV-positive and 14.8% reported never having been tested for HIV. Grounded theory analysis of transcripts from chat-room instant-message discussions identified 13 thematic categories related to chatter characteristics, prevention needs, and intervention delivery. Chatters were looking for sexual partners, were not open about their orientation, lacked basic information about HIV, had questions about how to be tested, and perceived a lack of general community resources to meet their needs. Furthermore, CyBER educators had to understand and respect the online culture, build trust, and deliver well-crafted and focused messages. Conclusions. Chat room-based interventions hold promise to systematically reach Internet communities of MSM, a group that is particularly at risk for infection with HIV and other sexually transmitted diseases.

Behavioral Risk Disparities in a Random Sample of Self-Identifying Gay and Non-Gay Male University Students

This Internet-based study was designed to compare health risk behaviors of gay and non-gay university students from stratified random cross-sectional samples of undergraduate students. Mean age of the 4,167 male participants was 20.5 (±2.7) years. Of these, 206 (4.9%) self-identified as gay and 3,961 (95.1%) self-identified as heterosexual. After adjusting for selected characteristics and clustering within university, gay men had higher odds of reporting: multiple sexual partners; cigarette smoking; methamphetamine use; gamma-hydroxybutyrate (GHB) use; other illicit drug use within the past 30 days and during lifetime; and intimate partner violence (IPV). Understanding the health risk behaviors of gay and heterosexual men is crucial to identifying associated factors and intervening upon them using appropriate and tailored strategies to reduce behavioral risk disparities and improve health outcomes.

Using Community-Based Participatory Research to Develop a Chat Room-Based HIV Prevention Intervention for Gay Men

Background: Although seeking sexual partners on the Internet is an identified risk factor for HIV and sexually transmitted disease infection among gay men and men who have sex with men (MSM), the medical literature lacks descriptions of the development, implementation, and evaluation of interventions for reducing infections among men who seek sexual partners online. Objectives: We sought to fill this gap by describing Cyber-Based Education and Referral/Men for Men (CyBER/M4M), an intervention designed to reduce HIV exposure and transmission among gay men and MSM who use geographically defined chat rooms. Methods: CyBER/M4M was developed by a community–university partnership that included gay men who had experience with seeking sexual partners online, and representatives from community-based organizations, the local Results: Two products emerged: the CyBER/M4M Training Manual, designed to facilitate training of lay health advisors known as CyBER/M4M Educators, and CyBER/M4M Resource Manual, designed as a reference for the Educators. Conclusions: Further research is clearly needed, but this work provides insight into the development, implementation, and evaluation of a chat room-based HIV prevention intervention using CBPR.

Sociocultural Determinants of HIV/AIDS Risk and Service Use among Immigrant Latinos in North Carolina.

Latinos in the United States have been disproportionately affected by the intersecting epidemics of HIV and sexually transmitted diseases. Using a community-based participatory research approach to problem identification, the objective of this study is to explore sociocultural determinants of HIV/AIDS risk and service use among immigrant Latino men living with HIV/AIDS in North Carolina. In-depth key-informant interviews with stake-holders (n = 8) and Latino men living with HIV/AIDS (n = 10) were conducted. Major themes identified among Latino men living with HIV/AIDS are misconceptions about HIV/AIDS prevention and treatment, intracommunity discrimination against individuals living with HIV, and feared discovery of their undocumented status. Further research is needed to reduce HIV risk and improve access to medical services among Latino men living with HIV/AIDS.

Condom Acquisition and Preferences within a Sample of Sexually Active Gay and Bisexual Men in the Southern United States

Health departments, community-based organizations (CBOs), and AIDS service organizations (ASOs) in the United States and abroad distribute large quantities of free condoms to sexually active individuals; however, little is known about where individuals who use condoms actually acquire them. This community-based participatory research (CBPR) study was designed to identify factors associated with the use of free condoms during most recent anal intercourse among self-identifying gay and bisexual men who reported condom use. Data were collected using targeted intercept interviewing during North Carolina Pride Festival events in Fall 2006, using the North Carolina Condom Acquisition and Preferences Assessment (NC-CAPA). Of the 606 participants who completed the assessment, 285 met the inclusion criteria. Mean age of participants was 33 (+/-10.8) years. The sample was predominantly white (80%), 50% reported being single or not dating anyone special, and 38% reported the use of free condoms during most recent anal intercourse. In multivariable analysis, participants who reported using free condoms during most recent anal sex were more likely to report increased age; dating someone special or being partnered; and having multiple male sexual partners in the past 3 months. These participants were less likely to report ever having had a sexually transmitted disease. Despite being in the third decade of the HIV epidemic, little is known about condom acquisition among, and condom preferences of, gay and bisexual men who use condoms. Although more research is needed, our findings illustrate the importance of free condom distribution.

Medications for sexual health available from non-medical sources: a need for increased access to healthcare and education among immigrant Latinos in the rural southeastern USA.

This study documented the types and quality of sexual health medications obtained by immigrant Latinos from non-medical sources. Samples of the medications were purchased from non-medical sources in the rural Southeast by trained native Spanish-speaking “buyers”. Medications were screened the presence of active pharmaceutical ingredients using mass spectrometry. Eleven medications were purchased from tiendas and community members. Six were suggested to treat sexually transmitted diseases, one was to treat sexual dysfunction, one was to prevent pregnancy, and two were to assist in male-to-female transgender transition or maintenance. All medications contained the stated active ingredients. Findings suggest that medications are available from non-medical sources and may not be used as indicated. Interventions that target immigrant Latinos within their communities and rely on existing structures may be effective in reducing barriers to medical and healthcare services and increasing the proper use of medications to reduce potential harm.

Correlates of HAART adherence among immigrant Latinos in the Southeastern United States.

Abstract We explored the relationships between sociocultural and psychological constructs and adherence to antiretroviral therapy among predominantly Spanish-speaking immigrant Latinos in the southeastern United States. A cross-sectional clinic-based sample of immigrant Latino men and women participated in an interviewer-administered assessment. Self-reported prevalence of adherence was assessed along with demographic characteristics, acculturation, physician trust, social support, and theory of planned behavior (TPB) constructs: attitude, subjective norm (SN), and perceived behavioral control (PBC). A total of 66 respondents met inclusion criteria. Average age was 38 years old, 74% of respondents were male, 71% heterosexual, and 86% reported being from Mexico or Central America. Prevalence of “complete” adherence (i.e., not missing a single dose) in the past 30 days was 71%. Social support was significantly and inversely associated with adherence, PBC, and attitude. Positive correlates of adherence included attitude, PBC, and employment status. In multivariable analysis, SN and PBC were significantly associated with social support, controlling for acculturation, physician trust, and number of behavioral referents. TPB constructs have utility in explaining ART adherence among immigrant Latinos in the “Deep South.” Further research is necessary to understand the complex relationships between social support, attribution processes, and ART adherence outcomes.

Effect of immediate initiation of antiretroviral therapy on risk of severe bacterial infections in HIV-positive people with CD4 cell counts of more than 500 cells per μL: secondary outcome results from a randomised controlled trial

Summary Background The effects of antiretroviral therapy on risk of severe bacterial infections in people with high CD4 cell counts have not been well described. In this study, we aimed to quantify the effects of immediate versus deferred ART on the risk of severe bacterial infection in people with high CD4 cell counts in a preplanned analysis of the START trial. Methods The START trial was a randomised controlled trial in ART-naive HIV-positive patients with CD4 cell count of more than 500 cells per μL assigned to immediate ART or deferral until their CD4 cell counts were lower than 350 cells per μL. We used Cox proportional hazards regression to model time to severe bacterial infection, which was defined as a composite endpoint of bacterial pneumonia (confirmed by the endpoint review committee), pulmonary or extrapulmonary tuberculosis, or any bacterial infectious disorder of grade 4 severity, that required unscheduled hospital admissions, or caused death. This study is registered with ClinicalTrials.gov, number NCT00867048. Findings Patients were recruited from April 15, 2009, to Dec 23, 2013. The data cutoff for follow-up was May 26, 2015. Of 4685 HIV-positive people enrolled, 120 had severe bacterial infections (immediate-initiation group n=34, deferred-initiation group n=86; median 2·8 years of follow-up). Immediate ART was associated with a reduced risk of severe bacterial infection compared with deferred ART (hazard ratio [HR] 0·39, 95% CI 0·26–0·57, p<0·0001). In the immediate-initiation group, average neutrophil count over follow-up was 321 cells per μL higher, and average CD4 cell count 194 cells per μL higher than the deferred-initiation group (p<0·0001). In univariable analysis, higher time-updated CD4 cell count (0·78, 0·71–0·85, p=0·0001) was associated with reduced risk of severe bacterial infection. Time-updated neutrophil count was not associated with severe bacterial infection. After adjustment for time-updated factors in multivariable analysis, particularly the CD4 cell count, the HR for immediate-initiation group moved closer to 1 (HR 0·84, 0·50–1·41, p=0·52). These results were consistent when subgroups of the severe bacterial infection composite were analysed separately. Interpretation Immediate ART reduces the risk of several severe bacterial infections in HIV-positive people with high CD4 cell count. This is partly explained by ART-induced increases in CD4 cell count, but not by increases in neutrophil count.

Female Sex Work Within the Rural Immigrant Latino Community in the Southeast United States: An Exploratory Qualitative Community-Based Participatory Research Study

Background: Little is known about the structure and context of, and the risks encountered in, sex work in the United States. Objective: This community-based participatory research (CBPR) study explored female sex work and the feasibility of conducting a larger study of sex work within the immigrant Latino community in North Carolina. Methods: Twelve abbreviated life story interviews were conducted with Latina women who sold sex, other women who sold sex to Latino men, and Latino men who hired sex workers. Content analysis was used to analyze narrative data. Results: Themes emerged to describe the structure of sex work, motivations to sell and hire sex, and the sexual health-related needs of sex workers. Lessons learned included the ease of recruiting sex workers and clients, the need to develop relationships with controllers and bar owners/managers, and the high compensation costs to reimburse sex workers for participation. Conclusions: Study findings suggest that it is possible to identify and recruit sex workers and clients and collect formative data within this highly vulnerable and neglected community; the prevention of HIV and STDs is a priority among sex workers, and the need for a larger study to include non-Latino men who report using Latina sex workers, other community insiders (e.g., bartenders), and service providers for Latina sex workers.
