Behavioral and social interventions to promote optimal HIV prevention and care continua outcomes in the United States

PURPOSE OF REVIEW

This review reports on trends in behavioral and social intervention research in the United States published over the past year (2020-2021) investigating HIV prevention and care outcomes, organized by the level of intervention focus - individual, dyadic, and organizational.

RECENT FINDINGS

Researchers have continued to develop and evaluate behavioral and social interventions to reduce HIV acquisition risk and disease progression. With few exceptions, social and behavioral interventions have primarily focused on individuals as the unit of behavior change. Interventions operating at the individual-, dyadic-, and organizational-level have made strides to reduce HIV transmission risk and disease progressing by addressing mental health, substance use, stigma, peer and romantic relationships, and, to some extent, structural vulnerabilities.

SUMMARY

Social and behavioral interventions continue to be critical in addressing HIV inequities in the United States. An important gap in the literature is the need for multilevel interventions designed and implemented within existing community-based organizations and local healthcare settings. We call on researchers to continue to attend to the structural, environmental, and economic vulnerabilities that shape HIV inequities in the development of multilevel approaches necessary to realize the full potential of existing and emerging HIV prevention and care strategies.

Projecting the number of new HIV infections to formulate the "Getting to Zero" strategy in Illinois, USA

OBJECTIVES

Getting to Zero (GTZ) initiatives focus on expanding use of antiretroviral treatment (ART) and pre-exposure prophylaxis (PrEP) to eliminate new HIV infections. Computational models help inform policies for implementation of ART and PrEP continuums. Such models, however, vary in their design, and may yield inconsistent predictions. Using multiple approaches can help assess the consistency in results obtained from varied modeling frameworks, and can inform optimal implementation strategies.

METHODS

A study using three different modeling approaches is conducted. Two approaches use statistical time series analysis techniques that incorporate temporal HIV incidence data. A third approach uses stochastic stimulation, conducted using an agent-based network model (ABNM). All three approaches are used to project HIV incidence among a key population, young Black MSM (YBMSM), over the course of the GTZ implementation period (2016-2030).

RESULTS

All three approaches suggest that simultaneously increasing PrEP and ART uptake is likely to be more effective than increasing only one, but increasing ART and PrEP by 20% points may not eliminate new HIV infections among YBMSM. The results further suggest that a 20% increase in ART is likely to be more effective than a 20% increase in PrEP. All three methods consistently project that increasing ART and PrEP by 30% simultaneously can help reach GTZ goals.

CONCLUSIONS

Increasing PrEP and ART uptake by about 30% might be necessary to accomplish GTZ goals. Such scale-up may require addressing psychosocial and structural barriers to engagement in HIV and PrEP care continuums. ABNMs and other flexible modeling approaches can be extended to examine specific interventions that address these barriers and may provide important data to guide the successful intervention implementation.

'I want the heart of fierceness to arise within us': maintaining public space to promote HIV-related health with House Ball Community members in an era of gentrification

The House Ball Community consists of sexual, gender and ethnic minority youth who form family-like houses and compete in balls. Many rely on community-based organisations as venues for socialising and accessing health-related resources. In recent years, urban gentrification has challenged the economic survival of the organisations that serve this community and its members. Between 2016 and 2017, we conducted 45 in-depth interviews with houses and gay families in the San Francisco Bay Area and regular participant observation at community events, including balls. In addition to forcing community organisations to close or move, rising rents have increased housing instability among Ballroom Community members, with some moving to distal locations. Participants felt nostalgia for organisations that provided HIV-related services and hosted balls in previous years, feeling the loss of space keenly. To maintain community and generate employment, the San Francisco Ballroom Community now offers Vogue classes at private dance studios. This allows participants to recruit new house members, welcoming a broader array of individuals into the community than those who have historically participated. However, accessing culturally appropriate sexual health services remains difficult. Health advocates should recognise that community organisations are necessary for diverse youth to build community and access sexual health services.
