Social network correlates of HIV risk-related behaviors among male migrants in China
Abstract Background Significant domestic and global research has focused on HIV risk among Chinaâs large internal migrant population. Much of this work takes an individual behavior approach while ignoring the critical role social networks play in shaping HIV risk. Methods Based on past studies among migrant men in China of yingchou activities (activities that build and reinforce social networks such as eating, drinking alcohol and patronizing commercial sex), we constructed ego-centric networks for a sample of 385 male migrants recruited from multiple worksites in Beijing. We used a nested-model approach to examine the contribution of social network characteristics to HIV risk at both the variable and model levels. Results As compared to an individual-level model, addition of social network variables significantly improved the fit of the models. Commercial sex norms and condom use norms of core yingchou networks were significantly associated with egosâ commercial sex and condom use respectively. The size of yingchou network was associated with egosâ commercial sex. The network models became more sensitive after network norm measures took into account the intimacy of network ties and allowed for egosâ uncertainty when reporting their altersâ sexual behaviors. Conclusion Results suggest the importance of social network factors and core network members in HIV transmission and risk-reduction interventions for male migrants. Future studies could explore other important social networks among male migrants, consider the intimacy of network ties and egosâ uncertainty about altersâ situations in constructing network norms, and refine the measurement of network size and density
Challenges in language services: Identifying and responding to patients\u27 needs
Objective: Identify characteristics of hospitalbased language services (LS), and describe practices of identifying patients with limited English proficiency (LEP) and interpreter training.
Participants: Seventy-one hospitals applied to participate in a national initiative. Applicants were non-federal, acute care hospitals with substantial LEP populations, at least 10,000 discharges, and in-person interpreters.
Methods: Descriptive statistics were generated on language, collection of language data, LEP volume and service utilization, staffing and training requirements and organizational structure. The relationship between admissions and encounters was analyzed.
Results Ninety percent of hospitals collect primary language data. Spanish is the most common language (93% of hospitals). We found no statistically significant correlation between admissions and encounters. Eighty-four percent require training. Eightynine percent have a designated LS department but no clear organizational home.
Conclusions: Hospital-based LS programs are facing challenges identifying patients with language needs, staffing and training a workforce, and creating an organizational identity. Need is not associated with utilization, suggesting that LS are not reaching patients
Developing and validating a new scale to measure the acceptability of health apps among adolescents
Background
The acceptability of health interventions is centrally important to achieving their desired health outcomes. The construct of acceptability of mobile health interventions among adolescents is neither well-defined nor consistently operationalized.
Objectives
Building on the theoretical framework of acceptability, these two studies developed and assessed the reliability and validity of a new scale to measure the acceptability of mobile health applications (âappsâ) among adolescents.
Methods
We followed a structured scale development process including exploratory factor analyses (EFAs), confirmatory factor analyses (CFAs), and employed structural equation modeling (SEM) to assess the relationship between the scale and app usage. Adolescent participants used the Fooducate healthy eating app and completed the acceptability scale at baseline and one-week follow-up.
Results
EFA (nâ=â182) determined that the acceptability of health apps was a multidimensional construct with six latent factors: affective attitude, burden, ethicality, intervention coherence, perceived effectiveness, and self-efficacy. CFA (nâ=â161) from the second sample affirmed the six-factor structure and the unidimensional structures for each of the six subscales. However, CFA did not confirm the higher-order latent factor model suggesting that the six subscales reflect unique aspects of acceptability. SEM indicated that two of the subscalesâethicality and self-efficacyâwere predictive of health app usage at one-week follow-up.
Conclusions
These results highlight the importance of ethicality and self-efficacy for health app acceptability. Future research testing and adapting this new acceptability scale will enhance measurement tools in the fields of mobile health and adolescent health
Advances in HIV Prevention for Serodiscordant Couples
Serodiscordant couples play an important role in maintaining the global HIV epidemic. This review summarizes biobehavioral and biomedical HIV prevention options for serodiscordant couples focusing on advances in 2013 and 2014, including World Health Organization guidelines and best-evidence for couples counseling, couples-based interventions, and the use of antiviral agents for prevention. In the past few years marked advances have been made in HIV prevention for serodiscordant couples and numerous ongoing studies are continuously expanding HIV prevention tools, especially in the area of pre-exposure prophylaxis. Uptake and adherence to antiviral therapy remains a key challenge. Additional research is needed to develop evidence-based interventions for couples, and especially for male-male couples. Randomized trials have demonstrated the prevention benefits of antiretroviral-based approaches among serodiscordant couples; however, residual transmission observed in recognized serodiscordant couples represents an important and resolvable challenge in HIV prevention
Strategies and outcomes of HIV status disclosure in HIV-positive young women with abuse histories
Young women with HIV and histories of physical and/or sexual abuse in childhood may be vulnerable to difficulties with disclosure to sexual partners. Abuse in childhood is highly prevalent in HIV-positive women, and has been associated with poorer communication, low assertiveness, low self worth, and increased risk for sexual and other risk behaviors that increase the risk of secondary transmission of HIV. HIV disclosure may be an important link between abuse and sexual risk behaviors. Qualitative interviews with 40 HIV-positive young women with childhood physical and/or sexual abuse were conducted; some women had also experienced adult victimization. Results suggest that HIV-positive women with abuse histories use a host of strategies to deal with disclosure of HIV status, including delaying disclosure, assessing hypothetical responses of partners, and determining appropriate stages in a relationship to disclose. Stigma was an important theme related to disclosure. We discuss how these disclosure processes impact sexual behavior and relationships and discuss intervention opportunities based on our findings
Networking Activities and Perceptions of HIV Risk Among Male Migrant Market Vendors in China
HIV research among internal migrants in China has not fully explored the contexts and perceptions of âriskâ. In 2011, urban markets in Liuzhou, China were mapped, and sixty male vendors, age 22 to 56, were selected for in-depth interviews on migration, social and family life, and perceptions and practices of sexual risk behavior. Participants were evenly divided among higher income shop and small stall vendors. All men were sexually active. Only the shop vendors reported non-marital sexual partners, including concurrent partners (n=15), commercial partners (n=10), and other sexual relationships (n=11). Shop vendors engaged in networking activities that facilitated commercial and non-commercial high-risk sex. Perceptions of HIV risk from commercial sex led some men to doubt the protective ability of condoms and rely on local (unproven) self-protection techniques. Networking activities played a role in high-risk sex and shaping migrants' risk perceptions and health practices. The networks created through these processes could also be used to facilitate health promotion activities
Unpacking the âstructuralâ in a structural approach for HIV prevention among female sex workers: A case study from China
Interventions for HIV prevention among female sex workers (FSWs) in China focus on HIV/sexually transmitted infection (STI) and individual behaviour change. An occupational health framework facilitates intervention across an array of health issues FSWs face including HIV/STI, violence, reproductive health, stigma and substance use. Through a case study of a community-based Jiaozhou (JZ) FSW programme, we developed a conceptual framework incorporating global discussions of structural approaches to HIV prevention with the specific social and structural contexts identified among FSWs in China. Based on ethnographic fieldwork between August 2010 and May 2013, we describe the evolution of this programme to its current occupational health focus and unpack the intervention strategies. We describe the critical features of the programme that have fostered success among FSWs including high-quality clinical services provided within a welcoming setting, responsive outreach work through staff and trained FSW peers, interpersonal and community-level engagement aimed at changing the local social and structural environments of sex work and tailored health education materials. This intervention differs from other projects in China by adopting a more holistic approach to FSW health that incorporates social issues. It also demonstrates the feasibility of structural interventions among FSWs even within an environment that has strong anti-prostitution policies
Social Contexts of Heterosexual Transmission of HIV/STI in Liuzhou City, China
In this special issue of AIDS and Behavior, we focus on the social contexts of sexual transmission of HIV/STI in one South China city. Our multiple projects grew from partnerships across the social and biomedical sciences, and with public health experts in Liuzhou City, to address critical gaps in knowledge about how social factors drive heterosexual transmission. The eleven articles that comprise this special issue feature multidisciplinary and mixed method approaches, collecting data in Liuzhou from different populations, environments, and social venues where individuals often find sexual partners. They document heterosexual behaviors and their meanings. They investigate the experiences and behaviors of women and men in social venues, exploring the networks of people within these venues, how they relate to one another, share information, and influence each other. The articles also examine the experiences of people living with HIV, again collecting data from multiple levels and sources, and revealing the ongoing power of stigma to shape these lives. Taken together, the articles demonstrate the critical role of social contexts in shaping behaviors and meanings, which are linked to heterosexual transmission of HIV/STI, and which must be taken into account for the development of appropriate and effective public health interventions
More than just tracking time: Complex measures of user engagement with an internet-based health promotion intervention
BACKGROUND: There has been a rise in internet-based health interventions without a concomitant focus on new methods to measure user engagement and its effect on outcomes. We describe current user tracking methods for internet-based health interventions and offer suggestions for improvement based on the design and pilot testing of healthMpowerment.org (HMP).
METHODS: HMP is a multi-component online intervention for young Black men and transgender women who have sex with men (YBMSM/TW) to reduce risky sexual behaviors, promote healthy living and build social support. The intervention is non-directive, incorporates interactive features, and utilizes a point-based reward system. Fifteen YBMSM/TW (age 20-30) participated in a one-month pilot study to test the usability and efficacy of HMP. Engagement with the intervention was tracked using a customized data capture system and validated with Google Analytics. Usage was measured in time spent (total and across sections) and points earned.
RESULTS: Average total time spent on HMP was five hours per person (range 0-13). Total time spent was correlated with total points earned and overall site satisfaction.
CONCLUSION: Measuring engagement in internet-based interventions is crucial to determining efficacy. Multiple methods of tracking helped derive more comprehensive user profiles. Results highlighted the limitations of measures to capture user activity and the elusiveness of the concept of engagement
HIV test uptake among MSM in China: Implications for enhanced HIV test promotion campaigns among key populations
Despite global efforts to increase HIV test uptake among men who have sex with men (MSM), social stigma and negative attitudes toward homosexuality hinder the effectiveness of traditional test promotion campaigns. Increasing HIV test uptake requires greater understanding of the conditions that facilitate decisions to get tested. We conducted an online survey hosted by two of the most highly frequented MSM web portals in China. A generalised ordered logistic regression analysis was conducted to determine factors associated with HIV testing behaviour. Compared to men who had never tested for HIV, men who had tested in the past year were more likely to have never engaged in sex with women, have multiple male sex partners in the past 3 months and have disclosed their sexual orientation to others. MSM found testing at local Chinese Centers for Disease Control and Prevention (80.7%), gay menâs community-based organisations (80.2%) and public hospitals (70.9%) to be acceptable, while saunas (50.5%) and gay bars (41.8%) were found to be unacceptable testing venues. Our study shows that MSM in China prefer to test at venues that guarantee confidentiality, quality and quick results. Our study also suggests that self-testing may be a feasible approach to increase test uptake
