Exploring the Interrelationships Between Physical Function, Functional Exercise Capacity, and Exercise Self-Efficacy in Persons Living with HIV.

PURPOSE: To determine if there were differences between the subjective and objective assessments of physical activity while controlling for sociodemographic, anthropometric, and clinical characteristics. SETTING/SAMPLE: A total of 810 participants across eight sites located in three countries. MEASURES: Subjective instruments were the two subscales of Self-efficacy for Exercise Behaviors Scale: Making Time for Exercise and Resisting Relapse and Patient-Reported Outcomes Measurement Information System, which measured physical function. The objective measure of functional exercise capacity was the 6-minute Walk Test. ANALYSIS: Both univariate and multivariant analyses were used. RESULTS: Physical function was significantly associated with Making Time for Exercise (ß = 1.76, p = .039) but not with Resisting Relapse (ß = 1.16, p = .168). Age (ß = -1.88, p = .001), being employed (ß = 16.19, p < .001) and race (ßs = 13.84-31.98, p < .001), hip-waist ratio (ß = -2.18, p < .001), and comorbidities (ß = 7.31, p < .001) were significant predictors of physical functioning. The model predicting physical function accounted for a large amount of variance (adjusted R2 = .938). The patterns of results predicting functional exercise capacity were similar. Making Time for Exercise self-efficacy scores significantly predicted functional exercise capacity (ß = 0.14, p = .029), and Resisting Relapse scores again did not (ß = -0.10, p = .120). Among the covariates, age (ß = -0.16, p < .001), gender (ß = -0.43, p < .001), education (ß = 0.08, p = .026), and hip-waist ratio (ß = 0.09, p = .034) were significant. This model did not account for much of the overall variance in the data (adjusted R2 = .081). We found a modest significant relationship between physical function and functional exercise capacity (r = 0.27). CONCLUSIONS: Making Time for Exercise Self-efficacy was more significant than Resisting Relapse for both physical function and functional exercise capacity. Interventions to promote achievement of physical activity need to use multiple measurement strategies.

Factors related to functional exercise capacity amongst people with HIV in Durban, South Africa.

BACKGROUND: People with HIV (PWH), who engage in regular physical activity, have improved fitness, muscular strength, body composition, health-related quality of life and mental health symptoms, but PWH have amongst the lowest physical activity levels of those with any chronic health condition. Furthermore, there is scant evidence examining these relationships in PWH in Africa. AIM: To address these critical gaps, this cross-sectional descriptive research study examined the relationships between demographic, HIV-related, anthropometric factors, neighbourhood walkability and physical activity, amongst PWH in Durban, South Africa. SETTING: Respondents (N = 100) were receiving primary healthcare in six eThekwini nurse-run municipal clinics. METHODS: Self-reported socio-demographic data were collected, and HIV-related medical data were extracted from respondent's medical charts. Height and weight were measured to calculate the body mass index (BMI, kg/m2); neighbourhood walkability was measured on the Neighbourhood Environment scale; and physical activity, specifically functional exercise capacity, was measured by the 6-min walk test (6MWT). RESULTS: On average, respondents were black African, female, approximately 38 years old and unemployed; men were of normal weight whilst women were overweight. Only 65% of the respondents reached the age- and sex-predicted distance during the 6MWT. Correlational analyses did not reveal any significant relationships between the functional exercise capacity and socio-demographic, HIV-related factors or anthropometric measures. CONCLUSION: South African PWH do not reach their predicated walking distance on the 6MWT. Engaging community agencies to promote walking as both a means of transportation and leisure physical activity may decrease the risks of a sedentary lifestyle and improve progression towards recommended physical activity targets.

Depression and social capital in people living with HIV.

WHAT IS KNOWN ON THE SUBJECT?: Depression affects 1 in 20 Americans, and people living with HIV experience depression at 2-3 times the rate of the general population. Recent research has shown that a person's level of social connectedness (e.g., social networks) is important to understanding their health and ability to get help when they need it. The scientific rationale of this work is to determine whether there is a direct relationship between levels of depression and a measure of social connectedness in people with HIV who are at higher than normal risk of depression and depressive symptoms. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: We examined the relationship between levels of depression and social capital in people living with HIV to determine whether depression may influence their beliefs about their social connectedness and available resources. We found that as depression increases, self-reported social capital decreases, suggesting that people living with HIV who are depressed may feel less socially connected and/or not be confident they can access resources when they need them. WHAT ARE THE IMPLICATIONS FOR PRACTICE: Mental health nurses are particularly well-positioned to help people living with HIV who are living with depression by helping them build skills for building and maintaining relationships, adhering to co-administered HIV and mental health medical treatments, and helping these individuals to identify and address barriers to social connectedness. Helping people living with HIV to address depression and promoting social connectedness can not only improve quality of life, but have major long-term health benefits. Abstract Introduction People living with HIV (PLWH) are disproportionately burdened by depression, with estimates as high as 80% of PLWH reporting depressive symptoms. Depression in PLWH is complex, and has been linked with biological and psychosocial causes, including low social capital. Few studies have examined the relationship between social capital and depression in PLWH. Aim/Question We conducted a secondary analysis of the relationship between social capital (Social Capital Scale score) and depression (Beck Depression Inventory-II scores) to determine whether depression predicted levels of social capital in a sample of 108 PLWH. Results Depression was significantly associated with lower social capital r(105) = -.465 p < .001. Depression remained a significant predictor of social capital in the linear regression model, F(5,101) = 8.508, p < .000, R2  = 0.296, when controlling for age and education level. Discussion Our results suggest that depression may be a significant predictor of low social capital, and these factors may have cyclical relationships that explain persistent depression in this population. Implications for practice Mental health nurses are particularly well-positioned to help PLWH who are living with depression by helping them build skills for building and maintaining relationships, adhering to co-administered HIV and mental health medical treatments, and helping these individuals to identify and address barriers to social connectedness.

The relationship of cardiorespiratory function, fatigue and depressive symptoms in PLHIV.

Fatigue and depressive symptoms are prevalent and associated with poor clinical outcomes, though the underlying physiological mechanisms of fatigue and depression are poorly understood. We examined the impact of cardiorespiratory fitness (CRF) on fatigue and depressive symptoms in one-hundred and nine PLHIV. CRF was examined by maximal cardiorespiratory stress test and determined by peak oxygen uptake. Patient-reported fatigue was examined utilizing the HIV-Related Fatigue Scale. Depressive symptoms were examined with the Beck Depression Inventory and PROMISE 29. Data was collected at baseline and six months. Generalized estimating equations were used to determine the effect of CRF on fatigue and depressive symptoms over time. Participants were approximately 53 years old, 86% African American (n = 93), and 65% male (n = 70). After controlling for age and sex, fatigue was inversely associated with CRF (ß = -0.163; p = .005). Depressive symptoms were not associated with CRF as measured by the BeckDepression Inventory (p = .587) nor PROMIS 29 (p = .290), but over time, depressive symptoms decreased (p = .051). Increased CRF was associated with decreased fatigue levels, but was not associated with depressive symptoms. These results should guide future research aimed at how CRF might inform interventions to improve fatigue in PLHIV.

Exploring Current Stereotypes and Norms Impacting Sexual Partner HIV-Status Communication.

This study sought to explore HIV-related stereotypes and norms that impact HIV-status communication with potential sexual partners. A series of focus groups and in-depth interviews were conducted (N = 59) with HIV-positive and HIV-negative MSM (75%) and Heterosexuals (25%). Findings indicate that HIV stereotypes and stigma remain as barriers to HIV-status discussion. Differences also emerged across groups: 1) HIV-negative MSM were more likely to report engaging in HIV-status communication, 2) HIV-positive MSM described inconsistent HIV-status communication and reported concealing their status at times, and 3) Heterosexuals reported being least likely to engage in HIV-status communication; often using the blanket question "Are you clean?" to encompass all STIs and avoiding direct HIV-status discussion. Overall, findings indicate that many HIV stereotypes and stigma-related communication norms persist that discourage discussion of sexual partners' HIV-status prior to sexual activity.

Relationships Between Physical Activity and Bone Density in People Living with HIV: Results from the SATURN-HIV Study.

We conducted a cross-sectional secondary analysis of baseline data from the SATURN-HIV study (N = 147; 78% male, 68% Black, median body mass index [BMI] 26.72 kg/m2, 13% with osteopenia, HIV-1 RNA < 1,000 copies/mL, stable antiretroviral therapy [ART]) to explore the relationship between physical activity (PA) and bone mineral density (BMD). We measured self-reported minutes of PA and BMD in the overall sample and subgroups based on national recommendations (≥150 minutes/week). Forty-one (28%) participants met recommended PA levels. Higher intensity PA was associated with higher BMD at the total hip (r = 0.27, p = .09; n = 41; 28%) and lumbar spine (r = 0.32, p < .05), and predicted higher BMD at the hip (p < .01; controlling for age, BMI, ART). Lumbar spine BMD did not retain significance in the regression model. Moderate-to-high intensity PA could prevent or mitigate excessive bone loss in people living with HIV.

People Living With HIV: Implications for Rehabilitation Nurses.

PURPOSE: The aim of this study was to present a brief overview of challenges faced by people living with HIV (PLHIV) as they age, to discuss the relevance of HIV to rehabilitation nurses, and to provide evidence-based recommendations for rehabilitation professionals working with PLHIV. DESIGN: Current issues article. METHODS: Literature review related to age-related comorbidities in PLHIV with implications for rehabilitation nurses. FINDINGS: Rehabilitation nurses must be prepared to address issues specific to people living with HIV including sensitivity and privacy regarding HIV status and increased risk of delayed or complicated healing. Rehabilitation nurses should also promote self-management behavior to optimize health in people living with HIV. CONCLUSIONS: Understanding unique characteristics of PLHIV as well as applying focused assessment and tailored interventions in PLHIV will give rehabilitation nurses the tools to successfully guide PLHIV through the rehabilitation process and optimize clinical outcomes. CLINICAL RELEVANCE: As people with HIV age and experience acute and chronic comorbidities, they will require the clinical expertise of rehabilitation nurses in the process to successfully transition through acute and subacute health care and regain function.

The Know∗Now Project: Facilitated Serosorting in HIV-Status Sexual Partner Communication.

An intervention was conducted providing access to clinic-verified HIV test results via a secure, web-based informatics platform to facilitate sexual partner HIV-status communication. Participants (N = 28) were men who have sex with men (MSM; HIV- n = 8, HIV+ n = 8) and heterosexuals (Non-MSM, n = 12). Focus groups with same-group members explored interest in using the intervention and baseline attitudes and practices relevant to serosorting. HIV-negative participants overwhelmingly expressed interest, regardless of MSM status. Interest among HIV-positive MSM was mixed. Six month follow-up interviews (n = 16) indicated 94% of all groups accessed the website, 69% had shown documented results to a sexual partner to initiate HIV-status discussion, and 88% reported future interest in using the 24/7 web-based tool with prospective sexual partners. Implications for future interventions facilitating HIV serosorting and sexual partner communication are discussed.

A multinational qualitative investigation of the perspectives and drivers of exercise and dietary behaviors in people living with HIV.

Globally, people living with HIV (PLWH) are at remarkably high risk for developing chronic comorbidities. While exercise and healthy eating reduce and mitigate chronic comorbidites, PLWH like many others, often fail to engage in recommended levels. We qualitatively examined the perspectives and contextual drivers of diet and exercise reported by PLWH and their health care providers. Two hundred and six participants across eight sites in the United States, Puerto Rico and Botswana described one overarching theme, Arranging Priorities, and four subthemes Defining Health, Perceived Importance of Diet and Exercise, Competing Needs, and Provider Influence. People living with HIV and their health care providers recognize the importance of eating a healthy diet and engaging in regular exercise. Yet there are HIV-specific factors limiting these behaviors that should be addressed. Health care providers have an important, and often underutilized opportunity to support PLWH to make improvements to their exercise and diet behavior.

Transitioning newly diagnosed patients with HIV into care.

Fewer than half of the individuals in the United States with HIV are receiving the full benefit of treatment. Primary care providers play a pivotal role in creating a pipeline into HIV care following diagnosis. Using interview data and current literature, this article provides recommendations for promoting care initiation for individuals newly diagnosed with HIV.

Fatigue Symptom Management in People Living With Human Immunodeficiency Virus.

Fatigue is a subjective, unpleasant, potentially disabling symptom rooted in physiological, psychological, and behavioral causes. People living with HIV are a population highly affected by fatigue due to risk factors associated with HIV-infection, treatment, and psychosocial disease burden. People with HIV are living longer, and are facing the challenge of a longer disease trajectory. Palliative nurses with expertise in symptom management can play a crucial role in helping people with HIV to engage in health behaviors that prevent or mitigate fatigue. In this paper we present a definition and overview of fatigue, describe the problem of fatigue in people living with HIV, and present a case study that illustrates the role of the palliative nurse in helping a person with HIV to cope with fatigue.

Evaluation of a Summer Bridge: Critical Component of the Leadership 2.0 Program.

BACKGROUND: Summer bridges facilitate the transition from high school to college. Although many schools employ summer bridges, few have published outcomes. This article's purpose is to share preconceptions of college by underrepresented and disadvantaged nursing students and describe important elements and long-term impact of a summer bridge, a component of the Leadership 2.0 program. METHOD: A longitudinal study design was used to collect baseline, short-term, and long-term post-summer bridge data. Methods included pre- and postsurveys, interviews, and focus groups. RESULTS: After bridge completion, students felt more prepared for the nursing program. Students ranked socialization components as most important. The summer bridge had lasting impact through the first year, where grade point average and retention of underrepresented and disadvantaged bridge students was comparable to the majority first-year students. CONCLUSION: The summer bridge was effective in preparing nursing students for the first year of college. Through holistic evaluation, unique aspects of socialization critical to student success were uncovered.
