Use of the Internet and mobile-based "apps" for sex-seeking among men who have sex with men in New York City.

The Internet continues to be a popular venue for men who have sex with men (MSM) to seek sexual partners. Increased sexual risk behavior has been linked to MSM who use the Internet to seek partners. However, there has been little research on how new mobile-based social networking applications (“apps”) may affect sex-seeking and sexual risk behaviors of MSM. One hundred twenty-six MSM in New York City were recruited to complete an online survey on the use of the Internet and other technology for sex-seeking. The authors collected data on variables of interest including sexual sensation seeking, gay identity affirmation, internalized homophobia, Internet/app use, and sexual behavior with men met via the Internet and mobile apps. Results indicated that men who use both the Internet and mobile apps to seek partners were younger and reported higher incomes (p < .05) than men who used the Internet only. There were no significant differences between the groups with regard to race, sexual sensation seeking, gay identity affirmation, or internalized homophobia, indicating that the use of mobile-based apps for sex-seeking may be simply an example of evolving technologies. These findings may provide insight for the feasibility and planning of effective mobile app-based HIV/STI programs for MSM.

Intersecting identities and the association between bullying and suicide attempt among New York city youths: results from the 2009 New York city youth risk behavior survey.

OBJECTIVES We examined the intersections of sexual minority, gender, and Hispanic ethnic identities and their interaction with experiences of bullying in predicting suicide attempt among New York City youths. METHODS We performed secondary data analysis of the 2009 New York City Youth Risk Behavior Survey, using logistic regression to examine the association of sexual identity, gender, ethnicity, and bullying with suicide attempt. We stratified results on these measures and reported adjusted odds ratios. RESULTS Compared with non-sexual minority youths, sexual minority youths had 4.39 and 1.96 times higher odds, respectively, of attempting suicide and reporting bullying. Identity variables did not interact with bullying in predicting suicide attempt individually; however, a four-way interaction term was significant. The effect of bullying on suicide attempt was strongest among non-Hispanic sexual minority male youths (odds ratio = 21.39 vs 1.65-3.38 for other groups). CONCLUSIONS Sexual minority, gender, and ethnic identities interact with bullying in predicting suicide attempt among New York City youths. Interventions to limit both the prevalence and the effect of bullying among minority youths should consider an intersectional approach that considers ethnic, gender, and sexual identities.

Expecting the unexpected: a mixed methods study of violence to EMS responders in an urban fire department

Background Struck by injuries experienced by females were observed to be higher compared to males in an urban fire department. The disparity was investigated while gaining a grounded understanding of EMS responder experiences from patient‐initiated violence. Methods A convergent parallel mixed methods design was employed. Using a linked injury dataset, patient‐initiated violence estimates were calculated comparing genders. Semi‐structured interviews and a focus group were conducted with injured EMS responders. Results Paramedics had significantly higher odds for patient‐initiated violence injuries than firefighters (OR 14.4, 95%CI: 9.2–22.2, P < 0.001). Females reported increased odds of patient‐initiated violence injuries compared to males (OR = 6.25, 95%CI 3.8–10.2), but this relationship was entirely mediated through occupation (AOR = 1.64, 95%CI 0.94–2.85). Qualitative data illuminated the impact of patient‐initiated violence and highlighted important organizational opportunities for intervention. Conclusions Mixed methods greatly enhanced the assessment of EMS responder patient‐initiated violence prevention. Am. J. Ind. Med. 59:150–163, 2016.

Drug use among men by sexual behaviour, race and ethnicity: prevalence estimates from a nationally representative US sample

BACKGROUND: Men who have sex with men (MSM) report drug use more frequently than non-MSM, however data are lacking that examine the disparity within racial and ethnic groups. METHODS: Using a nationally representative sample of men in the US stratified by race and ethnicity, we present prevalence estimates of self-reported drug use comparing MSM to non-MSM. RESULTS: Prevalence of self-reported drug use was greater among MSM compared to non-MSM, with the exception of heroin. White MSM reported greatest drug use overall, with amphetamine use representing the greatest disparity compared to black or Hispanic MSM. Hispanic MSM reported the greatest crack/cocaine and heroin use. Men who reported using drugs were younger then men who did not report using drugs; there were no age patterns of reported drug use among MSM. CONCLUSION: Drug use is a public health concern among MSM, compounding a racial and ethnic disparity. Intersectionality is a useful framework for identifying subgroups with highest reported rates of drug use. Language: en

A public health perspective on HIV/AIDS in Africa: Victories and unmet challenges

More than three decades after the first cases of HIV were recognized in the United States and worldwide, Africa remains a remarkable example of both public health successes and remaining challenges. Although many African countries initially lacked the resources and sociopolitical will to advance HIV treatment and prevention strategies, world governments, a committed scientific community, and activists have made tremendous advances. We present a public health perspective on the history of the HIV epidemic in Africa, combining summaries of the epidemiology of HIV infection rates and risk factors for horizontal and vertical HIV transmission, along with a historic perspective on programmatic and funding initiatives that have strongly reduced levels of HIV infection across the continent. In our preparation of this review two clear themes emerged: that (1) the HIV epidemic in Africa remains geographically and culturally heterogeneous, so that treatment and prevention strategies need to be thoughtfully tailored for maximal effectiveness; and (2) a lack of openness to recognize and discuss infection disparities in high risk groups, disseminate prevention information, and enact policies to partner with these highly stigmatized risk groups. This is especially true of female sex workers, people who inject drugs, and men who have sex with men, communities that are often not recognized or typically undercounted when HIV testing and prevention policies are developed by many African governments. Without changes to recognize and de-stigmatize these high-risk groups, a lack of sociopolitical will to alter public health perspectives will likely hinder advances to further curb the HIV epidemic.

What role does transactional sex play in the HIV/STI and reproductive health risk behaviour among high-tier entertainment centre workers in China?

Chinas rapid economic growth over the last three decades has led to increased population wealth and the proliferation of entertainment centres where people can conduct business, relax and meet new people. Little is known about the sexual risk behaviours of employees at high-tier entertainment centres. This paper addresses this gap in knowledge by comparing HIV risk perception and sexual and reproductive health behaviours among female and male employees at three high-tier entertainment centres in two cities in China, comparing those who report a history of transactional sex to those who do not. In both cities, participants who reported a history of transactional sex were more likely than those without a history of transactional sex to report multiple sexual partnerships, more lifetime sexual partners, a history of sexually transmitted infections (STIs), having anal sex and/or recent abortions, and were more likely to perceive themselves to be at risk for STIs/HIV. However, risk behaviour was also high among those with no history of transactional sex. These findings highlight the need for targeted sexual and reproductive health initiatives for employees in these work settings.

The Effect of PrEP on HIV Incidence Among Men Who Have Sex With Men in the Context of Condom Use, Treatment as Prevention, and Seroadaptive Practices

Background: HIV preexposure prophylaxis (PrEP) is an effective tool in preventing HIV infection among high-risk men who have sex with men (MSM). It is unknown how effective PrEP is in the context of other implemented HIV prevention strategies, including condom use, seroadaption, and treatment as prevention (TasP). We evaluate the impact of increasing uptake of PrEP in conjunction with established prevention strategies on HIV incidence in a high-risk population of MSM through simulation. Methods: Agent-based simulation models representing the sexual behavior of high-risk, urban MSM in the United States over the period of 1 year were used to evaluate the effect of PrEP on HIV infection rates. Simulations included data for 10,000 MSM and compared increasing rates of PrEP uptake under 8 prevention paradigms: no additional strategies, TasP, condom use, seroadaptive behavior, and combinations thereof. Results: We observed a mean of 103.2 infections per 10,000 MSM in the absence of any prevention method. PrEP uptake at 25% without any additional prevention strategies prevented 30.7% of infections. In the absence of PrEP, TasP, condom use, and seroadaptive behavior independently prevented 27.1%, 48.8%, and 37.7% of infections, respectively, and together prevented 72.2%. The addition of PrEP to the 3 aforementioned prevention methods, at 25% uptake, prevented an additional 5.0% of infections. Conclusions: To achieve a 25% reduction in HIV infections by 2020, HIV prevention efforts should focus on significantly scaling up access to PrEP in addition to HIV testing, access to antiretroviral therapy, and promoting condom use.

Sexual and reproductive health risk behaviours among South African university students: results from a representative campus-wide survey

Among South African university students, HIV prevalence is lower than in age-peers, but at 3.8% it is not negligible. We examined prevalence of factors potentially associated with HIV risk, focusing on partnership characteristics and consistent condom use. We hypothesised that contraceptive-related factors, for example, desire to prevent pregnancy and not using hormonal contraceptives, would be positively associated with consistent condom use. Data were drawn from a representative interviewer-administered survey of 2nd to 4th year students conducted during registration at a university campus in KwaZulu-Natal. Of 576 students, 218 (83 women, 135 men) reported vaginal intercourse in the past 2 months. Of these, 7% of women and 43% of men reported past-year concurrent partnerships, and 24% knew/ suspected partner non-monogamy. Although reported condom use at last intercourse was 90%, 2-month consistent use was 53% (women) and 73% (men). Reported hormonal contraception use was low (women: 36.8%; men: 16.7%), and 68% used condoms for dual protection. In gender-stratified multivariable analyses, consistent condom use was higher for men who reported their partner did not use (vs. used) hormonal contraception (aOR = 5.84; 95%CI = 2.71, 12.57; p < 0.001) and who reported using condoms for dual protection (vs. single protection) (aOR = 2.46; 95%CI = 1.43, 4.25; p = 0.001). No contraception-related factors were associated with consistent condom use among women. Sexual partnership characteristics potentially place sexually active university students at high HIV risk and should be investigated further. Among men, but not women, contraceptive concerns were associated with consistent condom use. Promoting condoms for dual protection may resonate with students and should be continued.
