Prevalence of STI symptoms and high levels of stigma in STI healthcare among men who have sex with men in Dar es Salaam, Tanzania: a respondent-driven sampling study

Peer-to-Peer Chain Recruitment for Enrolling Young South African Women into an HIV Pre-exposure Prophylaxis (PrEP) Intervention Study: How Did It Perform?

Peer-to-peer chain recruitment has been used for descriptive studies, but few intervention studies have employed it. We used this method to enroll sexually active women ages 18 to 25 into an online Pre-Exposure Prophylaxis (PrEP) information and motivation intervention pilot in eThekwini (Durban), South Africa. Seeds (N = 16) were recruited by study staff and randomized to Masibambane, Ladies Chat, a Gender-Enhanced group-based WhatsApp Workshop (GE), or Individual-Access (IA), a control condition that provided participants with online information/motivation materials only. Each seed could recruit up to three women to participate in the same study condition, with an incentive for each enrolled woman; participants in subsequent waves could choose to recruit or not. We evaluated if peer-to-peer recruitment was self-sustaining and resulted in enrolling women who, in subsequent waves, had less contact with the health care system and less knowledge about PrEP than the initial seeds. Over three recruitment waves beyond the seeds, 84 women were recruited. Almost 90% of women became recruiters, with each recruiting on average 1.90 women and 1.26 eligible enrolled women. The approach was successful at reaching women with less education but not women with less health system contact and PrEP knowledge across waves. IA participants had a slightly higher, though non-significantly different, percentage of individuals who became Peer Health Advocates (PHAs) than GE participants and, on average, they recruited slightly more women who enrolled. Our findings demonstrated that peer-to-peer recruitment is a feasible and self-sustaining way to recruit SA young women into a PrEP intervention study.

Cultural adaption and validation of the Explanatory Model Interview Catalogue-Community Stigma Scale in the assessment of public stigma related to schistosomiasis in lakeshore areas of Mwanza region, Tanzania

BACKGROUND

Previous qualitative studies on attitudes towards schistosomiasis demonstrated inconclusive results on the extent of stigma towards schistosomiasis in endemic communities around the world. The Explanatory Model Interview Catalogue-Community Stigma Scale (EMIC-CSS) has been used and validated for the assessment of public stigma across numerous countries in various health conditions. This study tested the performance of the scale in the context of stigma related to schistosomiasis in twelve communities in the three districts of Magu, Nyamagana and Ilemela in Mwanza region, Tanzania.

METHODOLOGY/PRINCIPAL FINDINGS

The 15-item-version of the EMC-CSS was first translated to Kiswahili language. The translation was discussed within the research team to retain the meaning of the items and implement cultural adaptations. Validation of the adapted EMIC-CSS scale was conducted following the framework of Herdman and Fox- Rushby. A pilot study with 41 participants from two communities provided the basis for testing the performance of each item and assessing the semantic and operational equivalence of the scales. In addition, eight qualitative focus group discussions (FGDs) were conducted to evaluate the conceptional equivalence of the EMIC-CSS. Finally, the performance of the adjusted scale was tested on 200 participants with a 50:50 male-female ratio from ten communities. The mean score of the EMIC-CSS M = 8.35 (SD = 6.63) shows clear indications for public stigma towards schistosomiasis. The EMIC-CSS demonstrated a good internal consistency with Cronbach's alpha α = .857 and no floor and ceiling effects.

CONCLUSION/SIGNIFICANCE

The results demonstrate that the EMIC-CSS is a useful instrument in assessing public stigma towards schistosomiasis and allow a clear recommendation of the EMIC-CSS for schistosomiasis in the Tanzanian culture. However, future studies are additionally recommended to address specific aspects and forms of the disease and how they contribute to the development of stigma towards schistosomiasis.

Prevalence of and factors associated with anal high-risk human papillomavirus in urban Tanzanian men who have sex with men, 2011-2012

Background: Anal cancer is primarily caused by high-risk human papillomavirus (hrHPV), is associated with HIV infection, and has a very high incidence among men who have sex with men (MSM). We assessed prevalence of hrHPV, and factors associated with hrHPV in anal canal specimens collected in Dar es Salaam, Tanzania from HIV-positive and HIV-negative MSM. Methods: MSM were recruited using respondent-driven sampling in this cross-sectional study. The primary outcome in this ancillary analysis of 116 MSM was prevalence of HPV-16 and other hrHPV types. Prevalence ratios (PR) estimated the association between hrHPV and HIV-negative participants' demographics, sexual behaviour and sexually transmitted infections. Results: Median age was 23 years and 33.6% of participants were HIV-positive. HrHPV and HPV-16 prevalence was 54.3% and 17.2%, respectively, with HPV-16 prevalence highest among HIV-positive MSM identifying as gay (36.1%) and lowest among HIV-negative MSM identifying as bisexual (2.9%). Having two or more receptive anal sex partners in the past month was associated with hrHPV (PR 3.20, 95%CI 1.69-6.07, vs. 0 partners) among HIV-negative MSM.Conclusions: HrHPV prevalence was high among MSM in Dar es Salaam and highest among HIV-positive MSM identifying as gay. These estimates may be used to support HPV vaccination and screening initiatives.

Factors Influencing the Intention of MSM to Use the PrEP Intelligent Reminder System

PURPOSE

Low adherence to medication is an important reason why pre-exposure prophylaxis (PrEP) is not effective at reducing the rate of new human immunodeficiency virus (HIV) infections among men who have sex with men (MSM). The intelligent reminder system (IRS) has been designed to improve user compliance, but the intention of MSM to use the IRS remains unclear. This study establishes a theoretical model to analyze the factors influencing their intention to use the IRS.

PATIENTS AND METHODS

Non-probability sampling was used to recruit MSM volunteers in Chongqing and Sichuan, China, and the data were collected from MSM who had used the IRS. A model based on the unified theory of acceptance and use of technology (UTAUT) was established for the data through a structural equation model, and the perceived privacy risk was considered to explore the subjects' behavior intention.

RESULTS

A total of 111 volunteers who had used the IRS filled out a questionnaire. Social influence had the greatest impact on behavior intention (β = 0.360, P < 0.001), followed by performance expectancy (β = 0.331, P < 0.001), and perceived privacy risk had a negative impact on behavior intention (β = -0.151, P = 0.040). In addition, social influence had an indirect effect on behavior intention (β = 0.182, P = 0.003) and performance expectancy played a mediating role in this indirect effect.

CONCLUSION

Developments in the IRS are required to improve its usefulness and adequately explain its role when recommending it to MSM. It is also important to improve the system's ability to protect user privacy. Clinical evidence for the effectiveness of the IRS is conducive to its widespread use.

'Fighting an uphill battle': a qualitative study of the challenges encountered by pharmacy workers when providing services to men who have sex with men in Dar es Salaam, Tanzania

Background

Previous research suggests that Tanzanian MSM might prefer consulting pharmacies and drugstores, rather than public healthcare services, when in need of STI medicines and treatment. Yet, few studies have explored the experiences of providing services to MSM clients among those working at pharmacies and drugstores and examined what challenges they encounter in providing these services.

Objective

To gain increased knowledge and understanding of the perceived challenges encountered by pharmacists and drugstore workers when providing STI services to MSM clients in Dar es Salaam, Tanzania.

Method

In early 2016, 16 semi-structured interviews were conducted with persons working at private pharmacies and drugstores in Dar es Salaam. Data were interpreted through qualitative content analysis.

Results

The overarching theme that emerged was labelled ‘Fighting an uphill battle’, which reflected the challenges pharmacy workers experienced during interactions with MSM clients, and in particular service provision. Pharmacy workers tried to act upon the best of their knowledge to meet the needs of clients, given their understanding of risks and obstacles that MSM faced. Yet, the lack of educational and professional preparedness and insufficient financial and human resources, regarded as necessary to meet the needs of a stigmatised client group, formed barriers for effective service delivery.

Conclusions

In order to support pharmacists and drug-store workers in Tanzania to address perceived challenges for service delivery to MSM clients, systematic and continuous training on MSM’s sexual health is required. Furthermore, inter-professional cooperation that harnesses provider involvement from all tiers in the healthcare system is essential to offer complementary services to ensure proper STI care and treatment. Thus, interventions that focus on inter-professional communication and interaction between pharmacists and physicians could have a positive impact on timely referrals of suspected STI cases among marginalised populations.

First Responses to the Symptoms of Sexually Transmitted Infections and Treatment-Seeking Behavior Among Men Who Have Sex With Men in 13 Cities in China

BACKGROUND

Data are scarce on sexually transmitted infection (STI) treatment-seeking behavior among men who have sex with men (MSM) in China. The purpose of the study was to characterize the first response to STI symptoms, treatment-seeking behavior, and its associated factors among MSM in China.

METHODS

A cross-sectional study with convenience sampling design was conducted in 13 cities from April to July 2017. Face-to-face interviews were conducted to collect information on demographics, STI symptoms, and treatment-seeking behavior. Logistic regression analysis was conducted to evaluate variables associated with not seeking treatment.

RESULTS

Among 3925 recruited participants, 628 (16.0%) reported STI symptoms in the past 12 months and were included in the analysis. Upon or after being notified of the symptoms, MSM sought help from various sources or self-tested using rapid testing kits. Only 322(51.3%) went to see a doctor in clinic. In multiple logistic regression analyses, younger age, lower income, less STI knowledge (adjusted odds ratio [AOR], 1.8; 95% confidence interval [CI], 1.2-2.5), not knowing own STI risk (AOR, 1.8; 95% CI, 1.2-2.7), no symptoms of anogenital ulcers (AOR, 2.3; 95% CI, 1.3-3.8) or anogenital warts (AOR, 2.4; 95% CI, 1.6-3.7), no syphilis testing in the past 12 months (AOR, 2.1; 95% CI, 1.5-3.0) were associated with higher probability of not seeking treatment in clinics.

CONCLUSIONS

We found a high prevalence of STI symptoms among MSM and only half sought treatment. Prevention efforts should promote STI education, testing, and adequate treatment-seeking behavior.

Challenges and key lessons learnt from its development and implementation are discussed.

Characterizing social cohesion and gender identity as risk determinants of HIV among cisgender men who have sex with men and transgender women in Côte d'Ivoire

PURPOSE

HIV prevalence has been previously estimated among cisgender men who have sex with men (MSM) in Côte d'Ivoire; however, limited data exist relating to the role of social cohesion and gender identity within this population. This study aims to examine these factors as risk determinants of HIV among MSM in Côte d'Ivoire.

METHODS

We conducted a cross-sectional study using respondent-driven sampling for recruitment with a structured sociobehavioral instrument and testing for HIV. After respondent-driven sampling adjustment, chi-squared tests and bivariate logistic regression and multivariate logistic regression analyses were performed to characterize social and identity-based risk determinants of biologically confirmed prevalent HIV infection.

RESULTS

HIV prevalence was 11.2% (n = 146/1301). Transgender woman identity was associated with higher odds of HIV compared with cisgender MSM (aOR = 3.4, 95% CI [2.0-5.8], P < .001). Having a combined social cohesion score of medium (aOR = 0.4, 95% CI [0.2-0.8], P < .01) or high (aOR = 0.2, 95% CI [0.1-0.3], P < .001) was associated with lower odds of HIV compared with a low score.

CONCLUSION

These data suggest that social cohesion is a determinant of prevalent HIV infection in Côte d'Ivoire among gay men, other cisgender MSM, and transgender women. The differences in HIV burden and social cohesion between transgender women and cisgender MSM highlight the need to better target the diversity of people traditionally included in the MSM umbrella to ensure comprehensive HIV prevention and treatment interventions.

Using pharmacists and drugstore workers as sexual healthcare givers: a qualitative study of men who have sex with men in Dar es Salaam, Tanzania

Background: Previous research has shown that men who have sex with men (MSM) avoid formal healthcare services because of the fear of discrimination as homosexuality is illegal and stigmatized in Tanzania. Instead, self-treatment by medications obtained directly from pharmacies or drugstores may be common when MSM experience symptoms of suspected sexually transmitted infections (STIs) related to sexual activity with men.

Objective: To explore MSM’s perceptions and experiences of seeking treatment and advice from pharmacists and drugstore workers in Dar es Salaam, Tanzania, with regards to their sexual health and STI-related problems.

Materials and Methods: 15 in-depth interviews were conducted with MSM with experience of seeking assistance relating to their sexual health at pharmacies and drugstores in Dar es Salaam in 2016. A qualitative manifest and latent content analysis was applied to the collected data.

Results: Four themes related to different aspects of MSM’s perceptions and experiences of pharmacy care emerged from the analysis: (1) Balancing threats against need for treatment reflected informants’ struggles concerning risks and benefits of seeking assistance at pharmacies and drugstores; (2) Identifying strategies to access required services described ways of approaching a pharmacist when experiencing a sexual health problem; (3) Seeing pharmacists as a first choice of care focused on informants’ reasons for preferring contact with pharmacies/drugstores rather than formal healthcare services; and (4) Lacking reliable services at pharmacies indicated what challenges existed related to pharmacy care.

Conclusions: MSM perceived the barriers for accessing assistance for STI and sexual health problems at pharmacies and drugstores as low, thereby facilitating their access to potential treatment. However, the results further revealed that MSM at times received inadequate drugs and consequently inadequate treatment. Multi-facetted approaches are needed, both among MSM and drugstore, pharmacy, and healthcare workers, to improve knowledge of MSM sexual health, STI treatment, and risks of antibiotic resistance.

Acting within an increasingly confined space: A qualitative study of sexual behaviours and healthcare needs among men who have sex with men in a provincial Tanzanian city

Objective

To explore risk perceptions, sexual practices and healthcare needs among men who have sex with men in the provincial city of Tanga in northern Tanzania. Previous research suggests that HIV/STIs are increasing problems for this population. Yet, few studies have been conducted outside the urban area of Dar es Salaam, which has limited our knowledge about the HIV/STI risk factors and healthcare needs among men who have sex with men who live outside major metropolitan areas.

Method

During three months in 2013, 10 in-depth interviews with men who have sex with men were conducted in Tanga. Data were interpreted through qualitative content analysis.

Results

The theme that emerged was labelled “Acting within an increasingly confined space”. The theme reflects the interference of stigma in men’s lives, and in the face of potential discrimination, men perceived their sexual and healthcare choices as limited. This created obstacles for forming romantic and sexual relationships, insisting on consistent condom use with sexual partners, maintaining open and conducive relationships with family, and accessing healthcare services when required.

Conclusions

Sexual stigma is a concern as it contributes to HIV/STI risk-related behaviours among men who have sex with men. Priority should be given to programmes that support same-sex practicing men in their efforts to make informed choices regarding their sexual health. Creating safe cyber networks provides an opportunity to reach this population with targeted sexual health education messages. Such programmes might be even more urgent in smaller towns and rural areas where gay specific initiatives are more limited than in urban areas.
