Differences in Healthcare and Everyday Discrimination among Racial and Ethnic Minority Cancer Survivors in the all of the US Research Program
A Socioecological Perspective on Sexual Health Promotion Choices Among Youth At-Risk for and Living with HIV in Los Angeles and New Orleans
Youth in the US remain at high relative risk for HIV and sexually transmitted infections compared to other age groups despite increasing diversity in the available tools to reduce HIV risk through behavioral strategies, biomedical methods, and treatment as prevention. Previous research has shown that acceptability and appeal of prevention methods vary across youth, and over-emphasis on any one strategy may overlook youth’s autonomy to make their …

PrEP Disparities Among Transgender Feminine, Transgender Masculine, Nonbinary, and Gender Expansive Youth and Young Adults in the United States
This study assessed disparities in pre-exposure prophylaxis (PrEP) use among transgender and gender expansive youth and young adults (N = 477) between 15 and 24 years old in the CARES (ATN 149) and TechStep (ATN 160) study protocols within the National Adolescent Medicine Trials Network for HIV/AIDS Interventions (ATN). Structural equation modeling was used to test mediation pathways between gender identity and PrEP uptake among the full sample a…
Online Peer Support for Youth at Higher Risk of or Living with HIV
With the rise of technology-based interventions for HIV risk reduction among adolescents, research is needed to assess how youth participate in these strategies. We used qualitative content analysis to examine youth's posts in an online peer support intervention through the Adolescent Trials Network (ClinicalTrials.gov NCT03134833, registered May 1, 2017) for youth at higher risk of or living with HIV. We analyzed 308 posts across 85 conversation…
Latent Class Analysis of Household and Community Adversity Among Pre-Adolescent Youth in the United States
The purpose of this study was to: 1) examine the co-occurrence of household and community adverse childhood experiences (ACEs) among preadolescent youth using latent class analysis (LCA), and 2) examine the association of ACE latent clusters to clinical-range scores on the Child Behavior Checklist (CBCL). Data came from the baseline and year 1 survey of the Adolescent Brain Cognitive Development (ABCD) Study with 10,915 youth recruited from schoo…
The Homeless Outreach Behavioral Screen (Hobs)
A necessary conversation to develop chatbots for HIV studies
Chatbots increase business productivity by handling customer conversations instead of human agents. Similar rationale applies to use chatbots in the healthcare sector, especially for health coaches who converse with clients. Chatbots are nascent in healthcare. Study findings have been mixed in terms of engagement and their impact on outcomes. Questions remain as to chatbot acceptability with coaches and other providers; studies have focused on cl…

Longitudinal Analysis of Overlapping Psychosocial Factors Predicting Incident Hospitalization Among Mixed HIV Serostatus Men who have Sex with Men in the Multicenter Aids Cohort Study
Strategies to Facilitate Service Utilization Among Youth at Risk for HIV
Sexual and gender minority youth (SGMY) are vulnerable to acquiring HIV and need HIV prevention and health services, but may have competing needs. A prior analysis found that PrEP use reports increased in a combination intervention study arm with coaching, peer support, and automated text-messages. This paper examines ancillary support and healthcare services utilization as secondary intervention objectives. SGMY (N = 895, 40% Black, 29% Latino) …
Exercise preferences for young people at-risk for and living with HIV
Exercise can improve physical and mental health for young people at risk for and with HIV, but prevalence rates remain low. This study explored exercise preferences and barriers among young people at risk for and with HIV, and potential gender differences. A total of 129 participants (66.7% male, mean age = 23.8 [SD = 2.1; range: 19-28], 35.7% Black/African American) at-risk for or with HIV were recruited from a larger study and completed an onli…
Psychiatric hospitalization among youth at high risk for HIV
Youth at-risk for HIV are also at-risk for mental health disorders and psychiatric hospitalization. Understanding the association between engagement in HIV prevention, concurrent risk behaviors, and psychiatric hospitalization may lead to improvements in integrated prevention and mental health treatment efforts. Youth at-risk for HIV, aged 14–24 years old, predominantly Black/African American and Latinx (75%) were recruited through youth-serving …
Intersection of Covid-19, HIV and exercise
The worldwide spread of COVID-19 has led to closures or reduced capacity of non-essential businesses and recreational areas and stay-at-home orders to promote social distancing. Although effective to reduce transmission, these policies may negatively impact exercise behaviors. Exercise is effective at mitigating the risk of developing or exacerbating several of underlining risk factors for a more severe COVID-19 disease course and may be particul…

Risk Behaviors Associated with Patterns of Sexualized Stimulant and Alcohol Use among Men Who Have Sex with Men
Association between Federally Qualified Health Center usage and emergency department utilization among California’s HIV-infected Medicaid beneficiaries, 2009
Federally Qualified Health Centers (FQHCs) have long been important sources of care for publicly insured people living with HIV. FQHC users have historically used emergency departments (EDs) at a higher-than-average rate. This paper examines whether this greater use relates to access difficulties in FQHCs or to characteristics of FQHC users. Zero-inflated Poisson models were used to estimate how FQHC use related to the odds of being an ED user an…
Adherence to self-monitoring healthy lifestyle behaviours through mobile phone-based ecological momentary assessments and photographic food records over 6 months in mostly ethnic minority mothers
Objective Mobile phones can replace traditional self-monitoring tools through cell phone-based ecological momentary assessment (CEMA) of lifestyle behaviours and camera phone-based images of meals, i.e. photographic food records (PFR). Adherence to mobile self-monitoring needs to be evaluated in real-world treatment settings. Towards this goal, we examine CEMA and PFR adherence to the use of a mobile app designed to help mothers self-monitor life…
Trauma, Family Factors and the Mental Health of Homeless Adolescents
Risky Sex and HIV Acquisition Among HIV Serodiscordant Couples in Zambia, 2002–2012
In this paper we evaluate the effects of heavy alcohol consumption on sexual behavior, HIV acquisition, and antiretroviral treatment (ART) initiation in a longitudinal open cohort of 1929 serodiscordant couples in Lusaka, Zambia from 2002 to 2012. We evaluated factors associated with baseline heavy alcohol consumption and its association with condomless sex with the study partner, sex outside of the partnership, and ART initiation using multivari…
Perceived mHealth barriers and benefits for home-based HIV testing and counseling and other care
Drug use and emotional distress differentiate unstably- versus stably-housed adults living with HIV who engage in unprotected sex
Among adults living with HIV, unstable housing is a barrier to health. Stably- and unstably-housed adults living with HIV were assessed for over 25 months. At baseline, unstably-housed adults living with HIV had a more recent HIV diagnosis, higher viral loads, worse physical and mental health, lower rates of antiretroviral therapy use and insurance coverage, and higher rates of hard drug use than stably-housed adults living with HIV. At follow-up…

A randomized controlled trial of home visits by neighborhood mentor mothers to improve children's nutrition in South Africa
Malnourished children and babies with birth weights under 2500 g are at high risk for negative outcomes over their lifespans. Philani, a paraprofessional home visiting program, was developed to improve nutritional outcomes for young children in South Africa. One "mentor mother" was recruited from each of 37 neighborhoods in Cape Town, South Africa. Mentor mothers were trained to conduct home visits to weigh children under six years old and to sup…
Perceived mHealth barriers and benefits for home-based HIV testing and counseling and other care
Reducing Risky Sexual Behavior and Substance Use Among Currently and Formerly Homeless Adults Living With HIV
Objectives. We examined the efficacy of the Healthy Living Program in reducing risky sexual behavior and substance use among adults with HIV infection who were marginally housed (i.e., homeless at some point over a 37-month period). Methods. We had previously conducted a randomized controlled trial with 936 adults living with HIV infection. In that study, 3 intervention modules of 5 sessions each addressed different goals: reducing risky sexual a…

Who Benefited from an Efficacious Intervention for Youth Living with HIV
Computerized HIV Preventive Intervention for Adolescents
We tested the hypothesis that a computerized intervention would be as efficacious as an in-person, small-group intervention in reducing sexual risk behaviors. The sexual behavior of high-risk adolescents in 3 intervention conditions was examined: (1) computer based, (2) small groups, and (3) control. Adolescents in the computerized intervention were significantly less likely to engage in sexual activity and reported significantly fewer partners. …

The longitudinal impact of HIV+ parents' drug use on their adolescent children
The impact of parental substance use on the emotional and behavioral adjustment of their adolescent children was examined over 5 years. A representative sample of 220 parents with HIV (PWH) and 330 adolescent children in New York City were repeatedly assessed. Some parents never used marijuana or hard drugs over the 5 years (nonusers). Among those who were users, substance use varied over time. PWH who used substances during a specific 3-month pe…
Mamekhaya
Nearly 30% of pregnant women in South Africa are estimated to be HIV seropositive, yet adherence to guidelines for the prevention of mother-to-child transmission of HIV (PMTCT) is often low. A pilot study was developed to see whether PMTCT services provided by the South African Government could be enhanced by the Mamekhaya program, a combination of the mothers2mothers peer-mentoring program and a culturally adapted cognitive-behavioral interventi…
Intervention Outcomes Among HIV-Affected Families Over 18 Months
Adjustment of trendy, gaming and less assimilated tweens in the United States
Youth transitioning from childhood to adolescence (tweens) are exposed to increasing amounts of media and advertisement. Tweens have also emerged as a major marketing segment for corporate America with increasing buying power.We examine how tweens relate to popular culture messages and the association of different orientations to popular culture on adjustment. A secondary data analysis was conducted on a marketing survey of 3527 tweens, aged 10-1…

Compliance to Cell Phone-Based EMA Among Latino Youth in Outpatient Treatment
Outpatient treatment practices for adolescent substance users utilize retrospective self-report to monitor drug use. Cell phone-based ecological momentary assessment (CEMA) overcomes retrospective self-report biases and can enhance outpatient treatment, particularly among Latino adolescents, who have been understudied with regard to CEMA. This study explores compliance to text message-based CEMA with youth (n = 28; 93% Latino) in outpatient treat…
