Background Medical mistrust is a barrier to engaging in HIV prevention and treatment, including testing and adherence to antiretroviral therapy. Research often focuses on how race and experiences of discrimination relate to medical mistrust, overlooking the role that other characteristics may play (e.g., history of physical abuse, diagnosis of mental illness). Furthermore, studies are often restricted to samples of men who have sex with men and findings may not generalize to other at-risk groups. Aims The current study explores a range of demographic, cognitive, behavioral, and social network correlates of medical mistrust. Method This study employed an egocentric network design among a racially diverse sample of at-risk women and women in their social networks ( n = 165). Results Results from multivariable linear regressions stratified by race (Black vs. others) indicate that medical mistrust is associated with both individual-level and network-level characteristics. Across both groups, age and experiences of racial discrimination were associated with higher medical mistrust. Having a regular sex partner and having a higher proportion of network members who are family was significantly associated with medical mistrust among non-Black women. Discussion Individual-level and network-level variables were significantly associated with medical mistrust. Therefore, interventions that attempt to mitigate medical mistrust as a barrier to HIV prevention and treatment should consider how mistrust may be related to characteristics of individuals and broader contexts. Conclusion Health interventions may benefit from conceiving of medical mistrust as a complex, rational response to cumulative discriminatory life experiences and a reflection of the networks within which individuals are embedded.

Abstract Background Neisseria gonorrhea (NG) has a long history of gaining resistance to nearly all antimicrobials used for treatment since the 1930s, which makes susceptibility to last-line cephalosporins of dire importance. Horizontal gene transmission is highly prevalent among the Neisseria genus, with genetic fragments from common commensal Neisseria having been found in resistant NG strains. Globally, NG disproportionately affects men-who-have-sex-with-men (MSM) and nearly all ceftriaxone-resistant cases have been reported from pharyngeal samples. Our study aims to assess the impact of antibiotic usage on the antimicrobial susceptibility of oropharyngeal Neisseria spp. Methods MSM from Hanoi, Vietnam, were surveyed regarding antibiotic usage. Pharyngeal swabs were collected and cultured on chocolate and modified-Thayer–Martin agar. Neisseria spp. were subcultured, identified using MALDI-TOF, and antimicrobial susceptibility determined by E-test using NG CLSI MIC breakpoints to ciprofloxacin (CIP), cefixime (CFM), ceftriaxone (CRO), and cefpodoxime (CPD). Results The 225 MSM surveyed were young (mean age 23.9 years, std 4.4). In the past 6 months: 41.6% participants used any antibiotics, among whom 62.4% did not have a prescription; 6.6% used CFM (16.4% more were unsure), among whom 55.6% did not have a prescription; and 4.5% received CRO. From 72 swabs, 102 Neisseria isolates were obtained; N. flavescens (n = 59), N. perflava (n = 14), N. macacae (n = 8), N. sublfava (n = 7), N. gonorrhoeae (n = 5), N. mucosa (n = 3), N. meningitides (n = 3), N. cinerea (n = 2), and N. lactamica (n = 1). 
“Reduced susceptibility” status for any Neisseria spp. was 35.3, 10, 8, and 30% to CIP, CFM, CRO, and CPD, respectively; 61.8% were “resistant” to CIP. MSM who took any antibiotics in the past 6 months were almost twice as likely to have Neisseria spp. with reduced susceptibility to cephalosporins (CFM, CRO, or CPD), RR 1.8 (95% CI 1.1–3.2; P = 0.026) compared with non-antibiotic users. Conclusion Many MSM in Hanoi used antibiotics recently, often without a prescription. Antibiotic use was associated with antimicrobial “reduced susceptibility” of commensal Neisseria spp. to cephalosporins, possibly potentiating resistance acquisition by NG.

Background: Sexually-transmitted disease (STD) is a facilitating cofactor that contributes to human immunodeficiency virus (HIV) transmission. Previous studies indicated a high prevalence of STDs among men who have sex with men (MSM) in China. To date, limited data are available for correlates of STD infection among young migrant MSM in China. The current study intends to examine the association between demographic and behavioral factors and STD infection. Methods: Data were collected from a sample of 307 migrant MSM aged 18–29 years in Beijing in 2009. Multivariate logistic regression analysis was employed to examine the factors associated with a history of STDs. Results: Results showed that about 13% of MSM reported a history of STDs. The average number of lifetime sexual partners was 15.0. About 56.7% of MSM did not use a condom at the first sexual encounter. The percentage of MSM who used a condom consistently was 47.4%. Multivariate logistic regression results showed that STD history was positively associated with education, income, the number of lifetime male sexual partners, and negatively associated with the frequency of properly using a condom. Conclusion: STD history was associated with socioeconomic status and sexual risk behaviors. The results suggested that HIV prevention intervention programs need to educate MSM to reduce the number of sexual partners and to use a condom properly. Furthermore, HIV prevention intervention programs among MSM need to be tailored to meet the needs of different socioeconomic groups of MSM.

BACKGROUND This is a case study from an HIV prevention project among young black men who have sex with men. Individual-level prevention interventions have had limited success among young black men who have sex with men, a population that is disproportionately affected by HIV; peer network–based interventions are a promising alternative. Facebook is an attractive digital platform because it enables broad characterization of social networks. There are, however, several challenges in using Facebook data for peer interventions, including the large size of Facebook networks, difficulty in assessing appropriate methods to identify candidate peer change agents, boundary specification issues, and partial observation of social network data. OBJECTIVE This study aimed to explore methodological challenges in using social Facebook networks to design peer network–based interventions for HIV prevention and present techniques to overcome these challenges. METHODS Our sample included 298 uConnect study respondents who answered a bio-behavioral survey in person and whose Facebook friend lists were downloaded (2013-2014). The study participants had over 180,000 total Facebook friends who were not involved in the study (nonrespondents). We did not observe friendships between these nonrespondents. Given the large number of nonrespondents whose networks were partially observed, a relational boundary was specified to select nonrespondents who were well connected to the study respondents and who may be more likely to influence the health behaviors of young black men who have sex with men. A stochastic model-based imputation technique, derived from the exponential random graph models, was applied to simulate 100 networks where unobserved friendships between nonrespondents were imputed. To identify peer change agents, the eigenvector centrality and keyplayer positive algorithms were used; both algorithms are suitable for identifying individuals in key network positions for information diffusion. For both algorithms, we assessed the sensitivity of identified peer change agents to the imputation model, the stability of identified peer change agents across the imputed networks, and the effect of the boundary specification on the identification of peer change agents. RESULTS All respondents and 78.9% (183/232) of nonrespondents selected as peer change agents by eigenvector on the imputed networks were also selected as peer change agents on the observed networks. For keyplayer, the agreement was much lower; 42.7% (47/110) and 35.3% (110/312) of respondent and nonrespondent peer change agents, respectively, selected on the imputed networks were also selected on the observed network. Eigenvector also produced a stable set of peer change agents across the 100 imputed networks and was much less sensitive to the specified relational boundary. CONCLUSIONS Although we do not have a gold standard indicating which algorithm produces the most optimal set of peer change agents, the lower sensitivity of eigenvector centrality to key assumptions leads us to conclude that it may be preferable. The methods we employed to address the challenges in using Facebook networks may prove timely, given the rapidly increasing interest in using online social networks to improve population health.
