Oropharyngeal cancers (OPCa) caused by HPV have emerged as one of the leading causes of malignancies caused by HPV infection. They are also significantly more likely to occur in males and in people with a history of oral sex with multiple partners. Gay and bisexual men are disproportionately affected by HPV-positive oropharyngeal cancers.

Building trust and therapeutic relationships between healthcare providers and patients are crucial for delivering high-quality, comprehensive sexual and reproductive health (SRH) services. Yet, while patients face substantial SRH disparities in Tanzania, little is known about health care professionals' [HCPs] SRH history-taking practices and experiences. This paper describes HCPs' interdisciplinary practices, experience in conducting SRH taking, and the critical lessons learned to optimize quality SRH care.

Background/aims: Sexual minorities are small and under-researched populations that are at disproportionate risk for cancer and poor cancer outcomes. Described as a "hidden population," the principal research challenge has been to develop effective methods to identify and recruit such cancer patients into cancer studies. Online recruitment strategies, as well as targeted clinic recruitment using patient-entered sexual orientation and gender identity data from electronic medical records have potential to transform recruitment, but studies testing the effects of how to recruit using these have not been published.

On December 11, 2013, the Indian Supreme Court recriminalized non-peno-vaginal sex under Sec. 377 of the Indian Penal Code (IPC), overturning a 2009 ruling that deemed IPC Sec. 377 unconstitutional.

In this manuscript, we report lessons learned from our efforts to recruit Indian men and transgender women/hijras who have sex with men into an online cross sectional study. Between September 2013 and May 2014, we implemented a seven-phased recruitment strategy that included the use of online and offline strategies to enroll a total of 449 participants into an online survey about recent sexual behavior and various psychosocial measures. The phases were implemented sequentially and cost-per-eligible participant was calculated.

Recruiting hidden populations into online research remains challenging. In this manuscript, we report lessons learned from our efforts to recruit methamphetamine-using men who have sex with men. Between July and October 2012, we implemented a four-phase recruitment strategy to enroll a total of 343 methamphetamine-using MSM into an online survey about recent substance use, sexual behavior, and various psychosocial measures.

Objective: The objective of this study was to explore disparities in weight and weight-related behaviors by transgender identity.

Methods: Cross-sectional regression models were fit using 2007-2011 College Student Health Survey data.

Results: Compared to non-transgender, transgender subjects (N=53) were more likely to be either underweight [adjusted relative risk (95% CI): 4.

Technology-enabled HIV research and prevention has emerged in the past 10 years as an exciting dynamic field that offers great potential to help bring HIV prevention efforts to scale in key risk communities. Evolutions in technologies and in HIV epidemics suggest mutual opportunities to reach most at risk populations in novel ways. New technologies cannot completely replace interventions and services currently delivered by the people.

Personal responsibility beliefs of HIV-positive individuals to protect sex partners are an important determinant of engagement in transmission risk behavior. However, the degree to which such beliefs vary across different partners is unknown. HIV-positive men who have sex with men (n = 248) completing an online survey rated their personal responsibility beliefs for partners met in up to four different ways: (a) in a bar; (b) through the internet; (c) in a public sex environment (PSE); or (d) through friends or family.

Online social media and mobile technologies hold potential to enhance adherence to antiretroviral therapy (ART), although little is known about the current use of these technologies among people living with HIV (PLWH). To address this gap in understanding, 312 PLWH (84% male, 69% White) US adults completed an online survey in 2009, from which 22 persons accepted an invitation to participate in one of two online focus groups. Results showed that 76% of participants with lower ART adherence used social networking websites/features at least once a week.

To inform health information targeting, we used cross-sectional data from 2577 HIV-negative MSM to identify groups of men who access similar sources. Offline, more men reported talking to a physician about HIV than about having sex with men; fewer than half attended a safer sex workshop. Online, men sought information primarily through Internet search engines, GLBT websites, or health websites.

The aims of this study were to describe the overall pattern and predictors of attitudes toward criminalizing unprotected sex without disclosure by persons living with HIV among a broad sample of men who have sex with men (MSM) living in the USA, and to examine whether attitudes and sexual risk behavior differ by states with HIV-specific laws or no such laws. Participants (n=1725) were recruited in a 3.5 month period to complete a cross-sectional 70-minute online survey assessing attitudes and high risk sexual behavior.

This study sought to identify how urban gay communities are undergoing structural change, reasons for that change, and implications for HIV prevention planning. Key informants (N=29) at the AIDS Impact Conference from 17 cities in 14 countries completed surveys and participated in a facilitated structured dialog about if gay communities are changing, and if so, how they are changing. In all cities, the virtual gay community was identified as currently larger than the offline physical community.
