The role of social support in the association between childhood trauma and depression among HIV-infected and HIV-uninfected individuals

Depression-Mediating Pathways From Household Adversity to Antiretroviral Therapy Nonadherence Among Children and Adolescents Living With HIV in Zambia: A Structural Equation Modeling Approach

BACKGROUND

In Zambia, half of children and adolescents living with HIV (CALWH) on antiretroviral therapy (ART) are virologically unsuppressed. Depressive symptoms are associated with ART nonadherence but have received insufficient attention as mediating factors in the relationship between HIV self-management and household-level adversities. We aimed to quantify theorized pathways from indicators of household adversity to ART adherence, partially mediated by depressive symptoms, among CALWH in 2 Zambian provinces.

SETTING

In July-September 2017, we enrolled 544 CALWH aged 5-17 years and their adult caregivers into a year-long prospective cohort study.

METHODS

At baseline, CALWH-caregiver dyads completed an interviewer-administered questionnaire, which included validated measures of recent (past 6 months) depressive symptomatology and self-reported past-month ART adherence (never versus sometimes or often missing medication doses). We used structural equation modeling with theta parameterization to identify statistically significant ( P < 0.05) pathways from household adversities (past-month food insecurity and caregiver self-reported health) to depression (modeled latently), ART adherence, and poor physical health in the past 2 weeks.

RESULTS

Most CALWH (mean age: 11 years, 59% female) exhibited depressive symptomatology (81%). In our structural equation model, food insecurity significantly predicted elevated depressive symptomatology ( ß = 0.128), which was associated inversely with daily ART adherence ( ß = -0.249) and positively with poor physical health ( ß = 0.359). Neither food insecurity nor poor caregiver health was directly associated with ART nonadherence or poor physical health.

CONCLUSIONS

Using structural equation modeling, we found that depressive symptomatology fully mediated the relationship between food insecurity, ART nonadherence, and poor health among CALWH.

Global Systematic Review of Common Mental Health Disorders in Adults Living with HIV

PURPOSE OF THE REVIEW

By reviewing the most recent common mental health disorders (CMHD) studies in people living with HIV (PLWH) (2018-2020), this review discusses the prevalence of CMHD, factors associated with CMHD in PLWH, mental health in PLWH from vulnerable groups, the impact of CMHD on HIV disease progression and adherence to antiretroviral therapy and the efficacy of different treatment approaches.

RECENT FINDINGS

After screening for eligibility 142 studies were included in the final systematic review. Only 27% of studies were conducted in Sub-Saharan Africa, which carries the highest burn of HIV disease globally. Despite the well-established increased risk of CMHD in PLWH, the current prevalence remains high, with studies reporting 28%-62% of PLWH having mental health symptoms.

CONCLUSION

Despite the significant challenges that CMHDs present to successful HIV treatment, there are many mental health treatments and interventions which can improve outcomes in PLWH and opportunities to task-shift and integrate mental health care with HIV care.

Profiles of trauma histories as predictors of depression among women living with HIV

This study examined co-occurring psychosocial problems among 120 women living with HIV (WLWH) in Washington, DC, USA. Participants completed a demographic survey, PHQ-9 (depressive symptoms), the Life Stressor Checklist (stressful events) and the PCL-C (PTSD symptoms in civilian populations). We calculated descriptive statistics and chi-square solutions for participant demographics. Classes of trauma history were established using latent class analysis (LCA). Latent indicators were extracted from participant self-reported traumatic histories on the LSC-R. Traumatic events have been found to be predictive of both depression. Latent class solution selection was guided by utility in evaluating and discriminating between classes as predictors of scales measuring depression or trauma exposure. Three distinct classes of trauma histories were identified: a high trauma (HT) class, an abuse/neglect (AN) class and a childhood trauma (CT) class. Binary logistic regression analyses determined whether trauma profiles predicted depression or PTSD after controlling for age, marital status, race and education. Participants in both the AN and CT class were over five times more likely than those in the HT class to endorse depressive symptoms. Classes differed significantly on whether they endorse depressive symptoms (p = .008) and marital status (p = .009), while PTSD appeared to trend toward significance (p = .085).

"I just keep quiet about it and act as if everything is alright" - The cascade from trauma to disengagement among adolescents living with HIV in western Kenya

INTRODUCTION

There are approximately 1.7 million adolescents living with HIV (ALHIV, ages 10 to 19) globally, including 110,000 in Kenya. While ALHIV experience poor retention in care, limited data exist on factors underlying disengagement. We investigated the burden of trauma among disengaged ALHIV in western Kenya, and its potential role in HIV care disengagement.

METHODS

We performed in-depth qualitative interviews with ALHIV who had disengaged from care at two sites, their caregivers and healthcare workers (HCW) at 10 sites, from 2018 to 2020. Disengagement was defined as not attending clinic ≥60 days past a missed scheduled visit. ALHIV and their caregivers were traced through phone calls and home visits. Interviews ascertained barriers and facilitators to adolescent retention in HIV care. Dedicated questions elicited narratives surrounding traumatic experiences, and the ways in which these did or did not impact retention in care. Through thematic analysis, a conceptual model emerged for a cascade from adolescent experience of trauma to disengagement from HIV care.

RESULTS

Interviews were conducted with 42 disengaged ALHIV, 34 caregivers and 28 HCW. ALHIV experienced a high burden of trauma from a range of stressors, including experiences at HIV disclosure or diagnosis, the loss of parents, enacted stigma and physical or sexual violence. A confluence of factors - trauma, stigma and isolation, and lack of social support - led to hopelessness and depression. These factors compounded each other, and resulted in complex mental health burdens, poor antiretroviral adherence and care disengagement. HCW approaches aligned with the factors in this model, suggesting that these areas represent targets for intervention and provision of trauma-informed care.

CONCLUSIONS

Trauma is a major factor underlying disengagement from HIV care among Kenyan adolescents. We describe a cascade of factors representing areas for intervention to support mental health and retention in HIV care. These include not only the provision of mental healthcare, but also preventing or addressing violence, trauma and stigma, and reinforcing social and familial support surrounding vulnerable adolescents. In this conceptualization, supporting retention in HIV care requires a trauma-informed approach, both in the individualized care of ALHIV and in the development of strategies and policies to support adolescent health outcomes.

Differential Item Functioning by HIV Status and Sexual Orientation of the Center for Epidemiological Studies-Depression Scale: An Item Response Theory Analysis

The Center for Epidemiological Studies-Depression Scale (CES-D) is the most widely used instrument to assess depressive symptoms in people living with HIV. However, its differential item functioning (DIF) by HIV status and sexual orientation has yet to be explored. This study examined DIF and measurement invariance of the CES-D using an item response theory (IRT) framework, and a more traditional factor analytic approach. Data from 841 HIV-infected and HIV-uninfected individuals, from Miami, Florida, were analyzed. Uniform DIF by HIV status was detected in Items 4, 12, and 16 from the Positive Affect factor. Nonuniform DIF was detected in Items 13 and 17. Uniform DIF by sexual orientation was detected in Items 2, 15, and 19, two of them from the Interpersonal factor. Nonuniform DIF was detected in Item 2. Using a factor analytic approach, the CES-D was invariant at the configural and metric levels by HIV and sexual orientation. These findings indicate that overall, however, using IRT, the magnitudes of DIF were negligible, the CED-D was somewhat invariant using factor analytic methods; the CES-D may be reliably used to compare by HIV status or sexual orientation.

Mediating Effects of Depressive Symptoms on Perceived Social Support and HIV Disclosure: Assessing Moderation by Sex

People living with HIV may decide to disclose their HIV-positive status after considering the benefits and costs. Studies have shown associations between perceived social support, depressive symptoms and HIV disclosure among men and women; however, research assessing the mediating pathway among these variables and the associated disparities by sex are lacking. Therefore, the aims of this study were to determine the association between perceived social support from family and friends and HIV disclosure to sexual partners; assess the mediating effects of depressive symptoms; and examine the disparities by sex. Participants included 147 men and 115 women living with HIV who took part in a disclosure intervention study. Mediation analyses were conducted to determine the direct and indirect associations between perceived social support from family and friends, depressive symptoms, and disclosure behavior. Depressive symptoms mediated the association between perceived social support (from family: β = 0.103, p = 0.019; and from friends: β = 0.111, p = 0.009) and HIV disclosure to sexual partners, specifically among women. However, these pathways were not statistically significant among men. Women living with HIV may benefit from two types of interventions: (1) Disclosure to sexual partners interventions, which aim to accentuate perceived social support from family and friends through attenuating depressive symptoms; and (2) Social support interventions, which may increase disclosure to sexual partners via reducing depressive symptoms.
