Testing a Model of Resilience to Develop an Intervention for Health Aging in Older HIV-Seropositive Adults

Name: GOLD III
Funder: NYU Provost Office Mega Grants Initiative
Dates: 5/1/2017
Principal Investigators: Perry Halkitis, PhD, MPH, Farzana Kapadia, PhD, MPH & Danielle C. Ompad, PhD
Description: Older (50+) people living with HIV/AIDS (PLWHA) experience increased mental (e.g. depression, stress, anxiety, substance use, etc.) and psychosocial burdens (e.g. ageism, homophobia/homonegatvitiy, diminished social capital and social support, and social isolation, etc.) that exacerbates their physical health (e.g. HIV and HIV-related conditions, other chronic, etc.) and, in turn, diminishes their overall health. These multiple health states comprising overall health are interrelated and influenced by HIV therapies, the aging process, and psychosocial and structural conditions. To ensure the overall health and well-being of older PLWHA, we must attend to HIV and HIV-related conditions as well as mental health, psychosocial burdens and the physical conditions that affect aging adults.

One understudied area of focus is the understanding how resilience may serve to buffer the effects that HIV/HIV therapies, aging, and social/structural conditions have on health. Resilience is operationalized as a trait or characteristic that equips individuals with the ability to buffer against stressful life events and maintain their overall health/well-being. This project aims to evaluate a theoretical model that delineates the role of resilience in relation to the overall health/well-being (mental, physical and social) of older adults living with HIV and against the aforementioned stressors that impact overall health.

Project 18 (P18) Neighborhood Study

Funder: National Institute of Mental Health / National Institutes of Health
Dates: 4/01/2016-3/31/2018
Principal Investigator: Dustin Duncan, ScD
Co-Investigators: Perry Halkitis, PhD, MPH & Rumi Chunara, PhD
Description: This project seeks to investigate spatial mobility across neighborhoods as well as relationships between Global Positioning System (GPS)-defined activity space neighborhoods and HIV risk among young men who have sex with men (MSM) in the New York City metropolitan area, through the use of innovative methodological approaches including real-time geospatial methods and geo-located Twitter posts. We will randomly enroll 250 young MSM in the NIH-funded P18 Cohort Study in the proposed study to address the aims of the research. Eligibility requirements include report having had sex with another male in the past 6 months; HIV-seronegative; self-report no restrictions to usual physical activity; and willingness to complete a two-week GPS protocol. Participants will wear the GPS device following protocols we have used in our previous feasibility research projects. Findings from the proposed research will impact HIV prevention intervention activities. First, this research will inform specific neighborhood-level policy interventions. For example, increasing community efforts to combat lesbian, gay, bisexual and transgender (LGBT) hate crime neighborhood rates through increased local police attention in high-crime locations may be an HIV prevention intervention. Second, given that we will know the travel patterns of young MSM, we can identify geographic locations for HIV testing/prevention interventions, which is an advancement of the literature as such interventions are not often spatially targeted. Finally, this research will also facilitate identifying geographic locations for recruiting young MSM in research studies (an improved method of venue-based sampling), in this understudied group.

Shabaab Study

Start Date: 10/15/2016
Principal Investigator: Paul Brown, MA
Co-Investigator: Perry Halkitis, PhD, MPH
Principal Investigator: Perry Halkitis, PhD, MPH
Description: The purpose of this pilot study is to learn more about the experiences of Arab men who have sex with men (MSM) in the United States; to survey and measure encounters with racism, ethnic and/or religious based discrimination and homophobia; and to find whether these experiences are associated with sexual risk behavior. Several research studies have shown associations between racial and ethnic discrimination, homophobia and sexual risk among other racial ethnic minority MSM in the U.S. However these associations have not yet been explored among Arab MSM. This pilot study seeks to shed light on a sorely understudied population.

Funder: National Institute of Allergy and Infectious Disease/National institutes of Health

Description: This ancillary study of HPV and HSV-1 and -2 infection as part of the P18 Cohort Study of racially/ethnically and socioeconomically diverse YMSM seek to (1) to detect cases of oral and anal HPV infection through site-specific PCR testing and clinically significant HPV subtype through serotyping and to estimate HPV persistence and clearance rates; (2) to identify uptake and completion of HPV vaccination via a combination of self-reported vaccination history in addition to New York State HPV vaccine registry verification; (3) to determine the prevalence and incidence of HSV-1 and HSV-2 by serology; (4) to estimate HIV risk among YMSM with and without HSV-1 and/or HSV-2 and to assess whether HSV infection explains racial/ethnic disparities in HIV risk; and (5) to determine the extent to which biological, behavioral, psychosocial and social/structural factors explain the likelihood of (a) oral/anal HPV infection, broadly and infection of HPV 6, 11, 16, and 18, specifically; (b) HPV vaccination uptake, (c) HSV-1 and HSV-2 infection, and (d) co-infections of HIV, HSV, and/or HPV.

Understanding the Barriers and Facilitators to Health Care Access among Young Gay Men

Funder: New York State AIDS Institute, New York State Department of Health
Dates: 4/1/2015-4/30/2016

Start Date: 9/1/2016
Description: This quantitative study seeks to more fully explicate the dynamics associated with accessing care among YWSW. We will (1) identify the extent to which YWSW have access to health care facilities that serve the LGBT population; (2) disentangle the roles that sexual orientation and sexual behavior may play in preventing the access of consistent and appropriate care of YWSW; (3) delineate the patterns by which YWSW.

Collective Trauma and Resilience among LGBTQ People in the Aftermath of the Orlando Mass Shooting

Dates: 07/27/2016 – 10/31/2016
Principal Investigator: Perry Halkitis, PhD, MPH
Student Investigator: Christopher Stults, MS, LMHC
Description: In the aftermath of traumatic events, including mass shootings, people in communities that were geographically close to the event often experience symptoms of trauma. However, the recent shooting in Orlando, FL, appears to have been motivated, at least in part, by hatred towards lesbian, gay, bisexual, transgender, and queer-identified (LGBTQ) people. As such, experiences of trauma among people in the LGBTQ community may extend far beyond the geographic confines of the Greater Orlando area. To assess this hypothesis, a brief Internet survey assessing collective trauma (i.e., trauma experienced by an entire community) will be advertised on LGBTQ email listservs and Facebook pages. LGBTQ people will be invited to complete the survey, which includes items intended to assess experiences of collective trauma and resilience in the face of such atrocities.

Heroin Cessation and HIV Risk: A Case-Control Study

Name: Change Study
Funder: National Institute on Drug Abuse / National Institutes of Health
Dates: 9/20/2007-7/31/2015
Principal Investigator: Danielle C. Ompad, PhD
Description: The purpose of this case-control study is to characterize the prognostic indicators, including HIV infection, for the positive outcome of sustained heroin cessation among persons with a prior history of chronic heroin use within economically disadvantaged, predominantly racial/ethnic minority neighborhoods in New York City (NYC). With drug use as a major risk factor for HIV and a chronic relapsing condition, identifying factors that promote sustained cessation can be key to enhancing HIV prevention and treatment efforts.

Assessing HIV/STI Risk in Emerging Adult Gay and Bisexual Men in Consensual Non-monogamous Relationships

Dates: 12/09/14-12/31/15
Funder: Doug Kirby Adolescent Sexual Health Research Grant, Rural Center for AIDS/STD Prevention
Principal Investigator: Christopher Stults, MS, LMHC
Description: The purpose of this qualitative study was to elucidate how consensual non-monogamous (e.g. open, polyamorous, monogamish, etc.) relationships relate to HIV/STI risk. The study aimed to describe different types of CNM relationships among large sample of urban YMSM, assess how different CNM relationship structures relate to sex risk, elucidate how partners in CNM relationships perceive their own risk for HIV/STIs, communicate about extradyadic sex, and negotiate sex practices.
