Mindfulness instruction for medication adherence among adolescents and young adults living with HIV
Adolescents and young adults (AYA) 13–24 years old make up a disproportionate 21% of new HIV diagnoses. Unfortunately, they are less likely to treat HIV effectively, with only 30% achieving viral suppression, limiting efforts to interrupt HIV transmission. Previous work with mindfulness-based stress reduction (MBSR) has shown promise for improving treatment in AYA living with HIV (AYALH). This randomized controlled trial compared MBSR with genera…
Gendered powerlessness in at-risk adolescent and young women
In the United States, youth aged 13–24 comprised approximately 21% of new HIV infections in 2017; 13% of these infections occurred among women, the majority of whom (86%) acquired HIV through heterosexual contact (Centers for Disease Control and Prevention. 2019a Centers for Disease Control and Prevention. (2019a). HIV and youth. Retrieved from https://www.cdc.gov/hiv/group/age/youth/index.html [Google Scholar]. HIV and youth. Retrieved from http…
Giving syphilis and gonorrhea to friends
Eliciting friendship networks of people diagnosed with syphilis and gonorrhea may find members of their sexual networks, drug use networks, or people of similar STI risk. Friendship networks include more diagnosed cases of syphilis and gonorrhea than sexual networks alone, especially among populations with many non-disclosing men who have sex with men (MSM) and women who have sex with women (WSW). Future research should evaluate whether this frie…
Exploratory and confirmatory factor analyses and invariance assessment of the perceived powerlessness scale among youth in Baltimore
Generalized perceived powerlessness is an important psychosocial construct that determines a wide range of health behaviors and outcomes. This study has two aims: (1) examine the structure of the newly developed perceived powerlessness scale using exploratory and confirmatory factor analyses and (2) assess the scale’s invariance across key demographic variables using multi-group confirmatory factor analysis among a random household sample of Afri…
The Longitudinal Association between Perceived Powerlessness and Sexual Risk Behaviors among Urban Youth
Does Venue Type Matter for HIV-Related Risk Behavior in Urban Adolescent and Young Adult Men Who Have Sex With Men
Venue-based strategies offer effective means of targeting men who have sex with men. Few studies have sought to focus on where younger men congregate and understand risk behaviors that may occur at lower (i.e., community centers) versus higher risk venues. Data from 1,311 young men who have sex with men (YMSM) aged 12- to 24-years-old recruited from publicly accessible venues was used to examine the association between venue type (bar/club, commu…
Sexual Partner Characteristics, Relationship Type, and HIV Risk Among a Community Venue-Based Sample of Urban Adolescent and Young Adult Men Who Have Sex With Men
Few studies have examined sexual partnerships and HIV risk in diverse samples of African American/Black and Hispanic/Latino adolescent and young adult men who have sex with men (YMSM), a group that have a high burden of HIV in the United States. A community-venue recruitment approach was used, which identified significant differences in HIV risk by sexual partner type among 1,215 YMSM. Those with casual partners had a higher number of sexual part…
Exploring the dynamics of ART adherence in the context of a mindfulness instruction intervention among youth living with HIV in Baltimore, Maryland
Youth living with HIV have sub-optimal rates of adherence to antiretroviral therapy (ART). Mindfulness instruction interventions have shown promise for improving medication adherence, but the effects and mechanisms of these interventions are still being explored among people living with HIV, including youth. In the context of a randomized controlled trial of the efficacy of a Mindfulness-Based Stress Reduction (MBSR) program on ART adherence and …
Mindfulness instruction for HIV-infected youth
HIV-infected youth experience many stressors, including stress related to their illness, which can negatively impact their mental and physical health. Therefore, there is a significant need to identify potentially effective interventions to improve stress management, coping, and self-regulation. The object of the study was to assess the effect of a mindfulness-based stress reduction (MBSR) program compared to an active control group on psychologi…

A cluster randomized trial of community mobilization to reduce methamphetamine use and HIV risk among youth in Thailand
Young African American male–male relationships
HIV disproportionately impacts young African American men who have sex with men (MSM). In this study, we sought to understand how previous relationship experiences and expectations for romantic relationships influence condom use among young African American MSM. Twenty African American MSM age 16 to 24 years completed a semi-structured interview and questionnaire on sexual experiences, romantic relationships, and sexual behavior. We identified th…
Youth health outcomes from the Connect-to-Protect coalitions to prevent adolescent HIV infections
We assessed the relationships among HIV-related social and behavioral outcomes resulting from an adolescent-focused HIV structural change initiative in eight urban sites operating Connect to Protect (C2P) coalitions. Over a 4-year period, annual cross-sectional panels of adolescents (N = 2,248) completed an audio-computer-assisted interview, providing data on satisfaction with their communities as adolescent-supportive environments, internalized …
Structural and Community Change Outcomes of the Connect‐to‐Protect Coalitions
Highlights Coalition mobilization can contribute to the creation of AIDS‐competent communities. HIV coalitions benefit from leaders who can confront political opposition to structural changes. Coalitions can contribute to addressing the structural factors that promote HIV‐risk among youth

Coalition formation to address structural determinants of methamphetamine use in Thailand
Despite two recent government-sponsored 'wars on drugs', methamphetamine use continues to be a pervasive problem in Thailand. Out of concern for reported human rights abuses, there has been a call from the international community to take a different approach from the government's 'zero tolerance'. This paper describes the adaptation of the Connect to Protect® coalition formation process from urban U.S. cities to three districts in northern Thaila…

Objectives. We explored gender role strain (GRS) arising from conflict between homosexuality and cultural conceptions of masculinity among young Black men who have sex with men (MSM). Methods. We conducted a categorical analysis (a qualitative, 3-stage, iterative analysis) of data from studies conducted in 2001 to 2006, which interviewed 35 men aged 18 to 24 years in 3 New York cities and Atlanta, Georgia. Results. Participants described rigid, o…
“Youth friendly” clinics
Linkage and engagement in care are critical corollaries to the health of HIV-infected adolescents. The adolescent HIV epidemic and adolescents' unique barriers to care necessitates innovation in the provision of care, including the consideration of the clinical experience. Little research has addressed how "youth friendly" clinics may influence care retention for HIV-infected youth. We conducted 124 interviews with providers, outreach workers, an…
Linking HIV-positive adolescents to care in 15 different clinics across the United States
Linkage to care is a critical corollary to expanded HIV testing, but many adolescents are not successfully linked to care, in part due to fragmented care systems. Through a collaboration of the National Institutes of Health (NIH), Centers for Disease Control and Prevention (CDC) and the Adolescent Trials Network (ATN), a linkage to care outreach worker was provided to ATN clinics. Factors related to linkage were explored to better understand how …
Identifying and Characterizing Places for the Targeted Control of Heterosexual HIV Transmission in Urban Areas
Are social organizational factors independently associated with a current bacterial sexually transmitted infection among urban adolescents and young adults
On the Modalities of the Domestic
This article focuses on experiences of the domestic-of houses, of intimacy and privacy-and what relation these bear to the kinds of sentiments about life which are given expression as fragile, endangered or fleeting. We think of singularity as lying in the potential for multiple domesticities that emerge at different times and are neither coterminous with family nor indeed with household. Based on fieldwork with African-American and Caribbean fam…
Staying Strong
This paper explores adolescents' definitions of what it means to be a man and a woman, the psycho-social context surrounding the formation of gender ideologies and their relationship to HIV/STI prevention. Semi-structured, in-depth interviews were conducted with fifty African-American adolescents living in Baltimore, Maryland. Female gender ideologies included economic independence, emotional strength and caretaking. Male gender ideologies emphas…

The Trade-Off between Hormonal Contraceptives and Condoms among Adolescents
Adolescents trade off between hormonal contraceptives and condoms according to partner type and perceived risks. Adolescents' dual-method use may improve if providers tailor counseling to adolescents' perceived risk of STDs and pregnancy, and if they address prevention of both as a related decision
Individuals' perceptions about their sex partners' risk behaviors
Individuals' perceptions about their sex partners' sexually transmitted disease (STD)‐ and human immunodeficiency virus (HIV)‐related risk behaviors may affect their sexual behavior. The objective of this study was to determine the agreement between individuals' perceptions about their main sex partners' risk behaviors and their main sex partners' self‐reported risk behaviors. One hundred individuals and their current main heterosexual partner we…

Socioeconomic differences in sexually transmitted disease rates among black and white adolescents, San Francisco, 1990 to 1992
This paper examines the effect of socioeconomic position on the differences in the 3-year rates (1990 to 1992) of reported cases of gonorrhea and chlamydia between Black and White adolescents, aged 12 to 20 years, residing in San Francisco. The crude relative risks for Blacks were 23.4 (95% confidence interval [CI] = 20.4, 27.8) for gonorrhea and 9.3 (95% CI = 8.3, 10.3) for chlamydia. Adjusting for poverty and occupational status, the relative r…
Relationships Between Perceived STD‐Related Stigma, STD‐Related Shame and STD Screening Among a Household Sample of Adolescents
Adolescents who view STDs as stigmatizing have a reduced likelihood of being screened, but it is unclear whether this relationship reflects their care seeking or providers' practice of offering STD screening at a routine health visit
Understanding Sex Partner Selection From the Perspective of Inner‐City Black Adolescents
CONTEXT: Black adolescents in inner‐city settings are at increased risk for HIV and other STDs. Sex partner characteristics, as well as individual behavior, influence individuals' STD risk, yet little is known about the process of sex partner selection for adolescents in this setting. METHODS: Semistructured in‐depth interviews were conducted during the summer and fall of 2002 with 50 inner‐city black adolescents (26 females and 24 males) who had…
Conflict Transformation, Stigma, and HIV‐Preventive Structural Change
Over the prior decade, structural change efforts have become an important component of community‐based HIV prevention initiatives. However, these efforts may not succeed when structural change initiatives encounter political resistance or invoke conflicting values, which may be likely when changes are intended to benefit a stigmatized population. The current study sought to examine the impact of target population stigma on the ability of 13 commu…
