Ethnic identity and social support as mediators between childhood sexual abuse and depression among black men who have sex with men

BACKGROUND

Survivors of childhood sexual abuse (CSA) often experience long-term adverse mental health effects, a trend that has been observed in research focusing on men who have sex with men (MSM), especially Black MSM.

OBJECTIVE

The aim of this study was to investigate the direct and indirect effects of childhood sexual abuse on depression symptoms among Black MSM through early sexual debut, histories of incarceration, ethnic identity, and social support. In addition, we examine the role of social support and ethnic identity as mediators of depression symptoms.

PARTICIPANTS AND SETTING

The HPTN 073 study enrolled and followed 226 HIV-uninfected Black MSM in three US cities (Los Angeles; Washington, DC; and Chapel Hill, North Carolina) from February 2013 to September 2015. Study participants were offered once-daily oral emtricitabine/tenofovir preexposure prophylaxis combined with counseling and followed for 52 weeks.

METHODS

A path analysis was used to examine direct and indirect effects of CSA experiences on depression symptoms through incarceration, early sexual debut ethnic identity, and social support, and to see whether social support and ethnic identity mediated the relationship between incarceration and depression symptoms.

RESULTS

Our results indicate that childhood sexual abuse was direct and positively associated with early sexual debut (β = 0.21, p < .001). Both ethnic identity (β = -0.14, p < .001) and social support (β = -0.82, p < .001) were direct and negatively associated with depressive symptoms.

CONCLUSION

Our research underscores the significant impact of CSA factors on the life trajectories of some Black MSM, including experiences such as incarceration, sexual debut, and depression symptoms.

Barriers and Facilitators to Long-Acting Injectable HIV Pre-Exposure Prophylaxis Implementation in Primary Care Since Its Approval in the United States

BACKGROUND

HIV pre-exposure prophylaxis (PrEP) is a highly effective method to mitigate the HIV epidemic, but uptake of PrEP has been slow and is associated with racial and gender disparities. Oral PrEP requires high levels of adherence to be effective, which may disadvantage certain high-risk groups. The first injectable HIV PrEP, a drug given every 2 months rather than as a daily pill, was approved by the US Food & Drug Administration in December 2021.

SETTING

A Family Medicine practice in a single health organization in the United States (November 2022 to February 2023).

METHODS

We conducted interviews with patients and key stakeholders to characterize factors affecting long-acting injectable (LAI) PrEP implementation. Data collection and analysis were guided by the Consolidated Framework for Implementation Research. Interviews were transcribed and analyzed using guided content analysis.

RESULTS

Twenty-five patients (n = 13) and practice stakeholders (n = 12) were interviewed. Overall, stakeholders described a very low uptake of LAI PrEP. Barriers to LAI PrEP included a lack of awareness, insurance and access issues, a lack of streamlined workflow, and a trust in pills over injectables. Facilitators to LAI PrEP implementation included the absence of a pill burden, a culture of shared decision making, and pharmacy support.

CONCLUSIONS

Although uptake has been slow, we have identified several promising strategies for improving rollout and implementation of LAI PrEP. Approaches that can bolster rollout of LAI PrEP include having an interdisciplinary care team that is supported by PrEP navigators and pharmacists and are informed by a patient-centered model of care to increase patient engagement and trust.

Latent Profile Patterns of Network-Level Norms and Associations with Individual-Level Sexual Behaviors: The N2 Cohort Study in Chicago

Individual-level behavior can be influenced by injunctive and descriptive social network norms surrounding that behavior. There is a need to understand how the influence of social norms within an individual's social networks may influence individual-level sexual behavior. We aimed to typologize the network-level norms of sexual behaviors within the social networks of Black sexual and gender minoritized groups (SGM) assigned male at birth. Survey data were collected in Chicago, Illinois, USA, between 2018 and 2019 from Black SGM. A total of 371 participants provided individual-level information about sociodemographic characteristics and HIV vulnerability from sex (i.e., condomless sex, group sex, use of alcohol/drugs to enhance sex) and completed an egocentric network inventory assessing perceptions of their social network members' (alters') injunctive and descriptive norms surrounding sexual behaviors with increased HIV vulnerability. We used Latent Profile Analysis (LPA) to identify network-level norms based on the proportion of alters' approval of the participant engaging in condomless sex, group sex, and use of drugs to enhance sex (i.e., injunctive norms) and alters' engagement in these behaviors (i.e., descriptive norms). We then used binomial regression analyses to examine associations between network-level norm profiles and individual-level HIV vulnerability from sex. The results of our LPA indicated that our sample experienced five distinct latent profiles of network-level norms: (1) low HIV vulnerability network norm, (2) moderately high HIV vulnerability network norm, (3) high HIV vulnerability network norm, (4) condomless sex dominant network norm, and (5) approval of drug use during sex dominant network norm. Condomless anal sex, group sex, and using drugs to enhance sex were positively and significantly associated with higher HIV vulnerability social network norm profiles, relative to low HIV vulnerability norm profiles. To mitigate Black SGM's HIV vulnerability, future HIV risk reduction strategies can consider using network-level intervention approaches such as opinion leaders, segmentation, induction, or alteration, through an intersectionality framework.

Examining the Role of Autonomy Support, Goal Setting, and Care Coordination Quality on HIV PrEP Adherence in Black Men Who Have Sex with Men: HPTN 073

Autonomy support is a concept that is derived from self-determination theory. Autonomy refers to the freedom to act as one chooses. The current study aimed to examine if autonomy support was associated with dried blood spot validated pre-exposure prophylaxis (PrEP) adherence, and whether the association was mediated by PrEP adherence goal setting and progress toward PrEP adherence goals. Our sample was drawn from Black men who have sex with men (MSM) from across three cities (Chapel Hill, NC; Los Angeles, CA; and Washington, DC) in the United States between February 2013 and September 2014. We used logistic regression to evaluate associations between study variables and path analysis to test mediation effects. Participants were, on average, 28 [standard deviation (SD) = 1.12] years old and 25% were unemployed. We found that MSM who experienced high autonomy support were more likely to adhere to PrEP [odds ratio (OR) = 1.17; 95% confidence interval: 1.00-1.38]. MSM who set PrEP adherence goals were more likely to adhere to PrEP. Moreover, MSM who reported making progress toward their goals were also more likely to adhere to PrEP. Finally, client perception of coordination quality enhanced the magnitude of the association between goal setting and goal progress and the effect size of goal progress on PrEP adherence. Autonomy support, goal setting, goal monitoring/evaluation, and care coordination quality influenced PrEP adherence among Black MSM. Our findings indicate that while it is important to set goals for PrEP adherence, goal setting may need to be accompanied by progress monitoring to achieve the maximal effect.

Freedom as Prevention: Mechanisms of Autonomy Support for Promoting HIV Pre-Exposure Prophylaxis Use and Condom Use among Black MSM in 3 US Cities-HPTN 073

Healthcare providers who use controlling or coercive strategies may compel short-term enactment of HIV and sexually transmitted infection prevention behaviors but may inadvertently undermine their client's motivation to maintain those behaviors in the absence of external pressure. Autonomous motivation refers to the self-emanating and self-determined drive for engaging in health behaviors. It is associated with long-term maintenance of health behaviors. We used structural equation modeling to investigate whether autonomy support was associated with increased odds of therapeutic serum levels of pre-exposure prophylaxis, through a pathway that satisfies basic psychological needs for autonomous self-regulation and competence regarding pre-exposure prophylaxis use. We also investigated whether autonomy support was associated with decreased odds of condomless anal intercourse via the same psychological needs-satisfaction pathway of autonomous self-regulation and competence regarding condom use. We tested these two theorized pathways using secondary data from a longitudinal sample of Black men who have sex with men from across three cities in the US (N = 226). Data from the sample fit the theorized models regarding the pathways by which autonomy support leads to the presence of therapeutic PrEP levels in serum (χ2 = 0.56; RMSEA = 0.04; CFI = .99, TLI = 0.98) and how it also leads to decreased odds of condomless anal intercourse (χ2 = 0.58; RMSEA = 0.03; CFI = 0.99; TLI = 0.98). These findings provide scientific evidence for the utility of self-determination theory as a model to guide intervention approaches to optimize the implementation and impact of PrEP for Black men who have sex with men.

Optimizing PrEP Continuance: A Secondary Analysis Examining Perceived Autonomy Support and Care Coordination Quality among Black MSM in HPTN 073

At the end of year 2018, it was estimated that in the United States over 1 million people were living with HIV. Although Black/African American individuals comprise an estimated 13.4% of the US population, as of 2019, they represented an estimated 42% of all new HIV diagnoses in 2018. PrEP use among Black men who have sex with men has not reached levels sufficient to have a population impact on HIV incidence. The purpose of this study was to examine whether high perceived autonomy support and care coordination quality were associated with PrEP continuation. Secondary analyses were conducted on data with 226 Black MSM in three US cities. Participants who were PrEP users and scored higher on autonomy support at week 8 were significantly more likely to continue PrEP (OR 1.48; 95% CI 1.04-2.11). Perception of coordination quality did not differ between PrEP users and non-users at any of the visits. Although coordination quality was not statistically significant, greater than half of PrEP users and non-PrEP users utilized the C4 services. Addressing social, individual, and structural barriers to PrEP may benefit Black MSM irrespective of their PrEP use.
