HIV-Related Wasting in HIV-Infected Drug Users in the Era of Highly Active Antiretroviral Therapy

BACKGROUND A decrease in the rate of human immunodeficiency virus (HIV) infection-related wasting has been reported in the era of highly active antiretroviral therapy (HAART). We investigated this concern in a hard-to-reach population of HIV-infected drug users in Miami, Florida. METHODS After informed consent was obtained, 119 HIV-infected drug users were administered questionnaires involving demographic, medical history, and food-security information. Blood samples were drawn for immunological and viral studies. HIV-related wasting over a period of > or =6 months was defined as a body mass index of <18.5 kg/m2, unintentional weight loss of > or =10% over 6 months, or a weight of <90% of the ideal body weight. RESULTS The prevalence of HIV-related wasting was 17.6%. A significantly higher proportion of those who experienced wasting (81%) reported that there were periods during the previous month when they went for > or =1 day without eating (i.e., food insecurity), compared with those who did not experience wasting (57%). Although a greater percentage of patients who experienced wasting were receiving HAART, their HIV RNA levels were more than twice as high (mean+/-standard deviation [SD], 166,689+/-238,002 copies/mL; median log HIV RNA level +/- SD, 10.2+/-2.7 log10 copies/mL) as those for the group that did not experience wasting (mean+/-SD, 72,156 +/- 149,080; median log HIV RNA level+/-SD, 9.2+/-2.3 log10 copies/mL). Participants who experienced wasting were more likely to be heavy alcohol drinkers and users of cocaine. In multivariate analysis that included age, sex, food security, alcohol use, cocaine use, viral load, and receipt of antiretroviral therapy, the only significant predictors of wasting were > or =1 day without eating during the previous month (odds ratio [OR], 1.96; 95% confidence interval [CI], 1.18-3.26; P=.01) and viral load (OR, 1.64; 95% CI, 1.00-2.69; P=.05). CONCLUSIONS HIV-related wasting continues to be common among HIV-infected drug users, even among HAART recipients. Food insecurity and viral load were the only independent predictors of wasting. The social and economic conditions affecting the lifestyle of HIV-infected drug users constitute a challenge for prevention and treatment of wasting.

Focus on Increasing Treatment Self-Efficacy to Improve Human Immunodeficiency Virus Treatment Adherence

PURPOSE Human immunodeficiency virus (HIV) treatment self-efficacy is the confidence held by an individual in her or his ability to follow treatment recommendations, including specific HIV care such as initiating and adhering to antiretroviral therapy (ART). The purpose of this study was to explore the potential mediating role of treatment adherence self-efficacy in the relationships between Social Cognitive Theory constructs and self- reported ART adherence. DESIGN Cross-sectional and descriptive. The study was conducted between 2009 and 2011 and included 1,414 participants who lived in the United States or Puerto Rico and were taking antiretroviral medications. METHODS Social cognitive constructs were tested specifically: behaviors (three adherence measures each consisting of one item about adherence at 3-day and 30-day along with the adherence rating scale), cognitive or personal factors (the Center for Epidemiology Studies Depression Scale to assess for depressive symptoms, the 12-Item Short Form Health Survey (SF-12) to assess physical functioning, one item about physical condition, one item about comorbidity), environmental influences (the Social Capital Scale, one item about social support), and treatment self-efficacy (HIV Adherence Self-Efficacy Scale). Analysis included descriptive statistics and regression. RESULTS The average participant was 47 years old, male, and a racial or ethnic minority, had an education of high school or less, had barely adequate or totally inadequate income, did not work, had health insurance, and was living with HIV/acquired immunodeficiency syndrome for 15 years. The model provided support for adherence self-efficacy as a robust predictor of ART adherence behavior, serving a partial mediating role between environmental influences and cognitive or personal factors. CONCLUSIONS Although other factors such as depressive symptoms and lack of social capital impact adherence to ART, nurses can focus on increasing treatment self-efficacy through diverse interactional strategies using principles of adult learning and strategies to improve health literacy. CLINICAL RELEVANCE Adherence to ART reduces the viral load thereby decreasing morbidity and mortality and risk of transmission to uninfected persons. Nurses need to use a variety of strategies to increase treatment self-efficacy.

Suicide From the Perspectives of Older Men Who Experience Depression: A Gender Analysis

Depression can be a pathway to older men’s suicide, yet the mechanisms by which this can occur are poorly understood. A qualitative study of 22 older men who self-identified or were formally diagnosed with depression was conducted to describe the connections between masculinity, depression, and suicide. Analyses of individual interviews revealed that cumulative losses around social bonds were central to older men’s depression, apathy for living, and thoughts about suicide. Prominent were men’s self-assessments of failing to fulfill breadwinner roles, judgments that led participants to ruminate on their shortcomings amid recognizing their older age as limiting opportunities for redemption. Stigma featured as a barrier for men acting on their suicidal thoughts, and guilt about the pain their suicide would evoke on family and friends was a strong deterrent for men’s self-harm. Overall, participants’ alignment to masculine ideals influenced both the connectedness and detachment between older men’s depression and suicide.

A cross-sectional description of social capital in an international sample of persons living with HIV/AIDS (PLWH)

BackgroundSocial capital refers to the resources linked to having a strong social network. This concept plays into health outcomes among People Living with HIV/AIDS because, globally, this is a highly marginalized population. Case studies show that modifying social capital can lead to improvements in HIV transmission and management; however, there remains a lack of description or definition of social capital in international settings. The purpose of our paper was to describe the degree of social capital in an international sample of adults living with HIV/AIDS.MethodsWe recruited PLWH at 16 sites from five countries including Canada, China, Namibia, Thailand, and the United States. Participants (n = 1,963) completed a cross-sectional survey and data were collected between August, 2009 and December, 2010. Data analyses included descriptive statistics, factor analysis, and correlational analysis.ResultsParticipants mean age was 45.2 years, most (69%) identified as male, African American/Black (39.9%), and unemployed (69.5%). Total mean social capital was 2.68 points, a higher than average total social capital score. Moderate correlations were observed between self-reported physical (r = 0.25) and psychological condition (r = 0.36), social support (r = 0.31), and total social capital. No relationships between mental health factors, including substance use, and social capital were detected.ConclusionsThis is the first report to describe levels of total social capital in an international sample of PLWH and to describe its relationship to self-reported health in this population.

Engagement with health care providers affects self- efficacy, self-esteem, medication adherence and quality of life in people living with HIV

The engagement of patients with their health care providers (HCP) improves patients’ quality of life (QOL), adherence to antiretroviral therapy, and life satisfaction. Engagement with HCP includes access to HCP as needed, information sharing, involvement of client in decision making and self-care activities, respect and support of the HCP for the client’s choices, and management of client concerns. This study compares country-level differences in patients’ engagement with HCP and assesses statistical associations relative to adherence rates, self-efficacy, self-esteem, QOL, and symptom self-reporting by people living with HIV (PLHIV). A convenience sample of 2,182 PLHIV was enrolled in the United States, Canada, Puerto Rico, Namibia, and China. Cross-sectional data were collected between September 2009 and January 2011. Inclusion criteria were being at least 18 years of age, diagnosed with HIV, able to provide informed consent, and able to communicate in the local language with site researchers. In the HCP scale, a low score indicated greater provider engagement. Country comparisons showed that PLHIV in Namibia had the most HCP engagement (OR 2.80, p < 0.001) and that PLHIV in China had the least engagement (OR −7.03, p < 0.0001) compared to the PLHIV in the Western countries. Individuals having better HCP engagement showed better self-efficacy for adherence (t = −5.22, p < 0.0001), missed fewer medication doses (t = 1.92, p ≤ 0.05), had lower self-esteem ratings (t = 2.67, p < 0.01), fewer self-reported symptoms (t = 3.25, p < 0.0001), and better overall QOL physical condition (t = −3.39, p < 0.001). This study suggests that promoting engagement with the HCP is necessary to facilitate skills that help PLHIV manage their HIV. To improve ART adherence, HCPs should work on strategies to enhance self-efficacy and self-esteem, therefore, exhibiting fewer HIV-related symptoms and missing less medication doses to achieve better QOL.

Associations between the legal context of HIV, perceived social capital, and HIV antiretroviral adherence in North America

BackgroundHuman rights approaches to manage HIV and efforts to decriminalize HIV exposure/transmission globally offer hope to persons living with HIV (PLWH). However, among vulnerable populations of PLWH, substantial human rights and structural challenges (disadvantage and injustice that results from everyday practices of a well-intentioned liberal society) must be addressed. These challenges span all ecosocial context levels and in North America (Canada and the United States) can include prosecution for HIV nondisclosure and HIV exposure/transmission. Our aims were to: 1) Determine if there were associations between the social structural factor of criminalization of HIV exposure/transmission, the individual factor of perceived social capital (resources to support one’s life chances and overcome life’s challenges), and HIV antiretroviral therapy (ART) adherence among PLWH and 2) describe the nature of associations between the social structural factor of criminalization of HIV exposure/transmission, the individual factor of perceived social capital, and HIV ART adherence among PLWH.MethodsWe used ecosocial theory and social epidemiology to guide our study. HIV related criminal law data were obtained from published literature. Perceived social capital and HIV ART adherence data were collected from adult PLWH. Correlation and logistic regression were used to identify and characterize observed associations.ResultsAmong a sample of adult PLWH (n = 1873), significant positive associations were observed between perceived social capital, HIV disclosure required by law, and self-reported HIV ART adherence. We observed that PLWH who have higher levels of perceived social capital and who live in areas where HIV disclosure is required by law reported better average adherence. In contrast, PLWH who live in areas where HIV transmission/exposure is a crime reported lower 30-day medication adherence. Among our North American participants, being of older age, of White or Hispanic ancestry, and having higher perceived social capital, were significant predictors of better HIV ART adherence.ConclusionsTreatment approaches offer clear advantages in controlling HIV and reducing HIV transmission at the population level. These advantages, however, will have limited benefit for adherence to treatments without also addressing the social and structural challenges that allow HIV to continue to spread among society’s most vulnerable populations.

Antiretroviral Therapy Adherence: Testing a Social Context Model Among Black Men Who Use Illicit Drugs

&NA; Individuals living with HIV who receive treatment and optimal care live longer and healthier lives. The purpose of this study was to develop a theoretical model to understand the effects of social context factors (individual, interpersonal, and social capital) that influence antiretroviral therapy (ART) adherence among a sample of HIV‐infected Black men who use illicit drugs (N = 160). Ecosocial theory and social epidemiology provided the theoretical framework for this study. Multiple regression techniques and path analysis were used to test the model for these subjects. Homelessness among the subjects significantly affected adherence to ART. Tolerability of ART was observed to have a greater indirect effect on ART adherence than a direct effect. A positive state of mind and current illicit drug use indirectly affected ART adherence; however, significance was not achieved. Implications for the use of this theoretical model to guide research, clinical practice, and policy as part of a human rights approach to HIV disease is articulated.

The Process of Safer Crack Use Among Women in Vancouver’s Downtown Eastside

In this article we discuss the findings from a grounded theory study in which we explored how women residing in Vancouver’s Downtown Eastside (DTES) minimized some of the physical, psychological, and interpersonal harms associated with crack cocaine use, and identify the social, economic, and political factors that influence safer use. Data were collected over a 3-month period and involved group interviews with 27 women at an agency run by drug users in the DTES. A preliminary theory of safer crack use is discussed, consisting of the central phenomenon of caring for self and others. In addition, four thematic processes are described: (a) establishing a safe physical space, (b) building trusting relationships, (c) learning about safer crack use, and (d) accessing safer equipment. Implications of the findings are discussed in relation to supporting women’s efforts and improving health outcomes.

Use of a brief version of the self-compassion inventory with an international sample of people with HIV/AIDS

The objective of this study was to extend the psychometric evaluation of a brief version of the Self-Compassion Scale (SCS). A secondary analysis of data from an international sample of 1967 English-speaking persons living with HIV disease was used to examine the factor structure, and reliability of the 12-item Brief Version Self-Compassion Inventory (BVSCI). A Maximum Likelihood factor analysis and Oblimin with Kaiser Normalization confirmed a two-factor solution, accounting for 42.58% of the variance. The BVSCI supported acceptable internal consistencies, with 0.714 for the total scale and 0.822 for Factor I and 0.774 for Factor II. Factor I (lower self-compassion) demonstrated strongly positive correlations with measures of anxiety and depression, while Factor II (high self-compassion) was inversely correlated with the measures. No significant differences were found in the BVSCI scores for gender, age, or having children. Levels of self-compassion were significantly higher in persons with HIV disease and other physical and psychological health conditions. The scale shows promise for the assessment of self-compassion in persons with HIV without taxing participants, and may prove essential in investigating future research aimed at examining correlates of self-compassion, as well as providing data for tailoring self-compassion interventions for persons with HIV.

Personas to Guide Understanding Traditions of Gay Men Living With HIV Who Smoke

Gay men living with HIV (GMLWH) who smoke are less responsive to generalized smoking reduction and cessation (SRC) programs than heterosexual persons. This study explored perspectives of GMLWH during the design of a web-based SRC intervention. Participatory design techniques were used to guide the creation of personas that are composite representations of a person who would use the web-based SRC intervention. Researcher-participants (n = 13) created all data. Data analysis involved thematic coding drawing from an ethnographic perspective. Thematic analysis revealed seven intersecting themes related to SRC among participants, and an overarching theme navigating life. Concepts drawn from our ethnographic approach highlight cultural differences between GMLWH and mainstream society. Personas offer a mechanism for interpreting experiences and traditions of GMLWH. SRC interventions with GMLWH must address their social realities that include tools for navigating life, disease, and social identity.
