BackgroundPeople with HIV are living longer with the health-related consequences of HIV, multi-morbidity, and aging. Exercise is a key strategy that may improve or sustain health for people living with HIV. Our aim was to examine the safety and effectiveness of aerobic exercise interventions on immunological, virological, cardiorespiratory, strength, weight, body composition, and psychological outcomes in adults living with HIV.MethodsWe conducted a systematic review using the Cochrane Collaboration protocol. We searched databases up to April 2013. We included randomized controlled trials comparing aerobic exercise with no exercise or another intervention performed at least three times per week for at least four weeks among adults living with HIV. Two reviewers independently determined study eligibility. Data were extracted from studies that met inclusion criteria using standardized forms. We assessed risk of bias using the Cochrane Collaboration’s tool for assessing risk of bias. Outcomes were analyzed as continuous and meta-analyses conducted using random effects models with Review Manager (RevMan) computer software.ResultsTwenty-four studies met inclusion criteria (n = 936 participants at study completion); the majority of participants were men (73 %) and the majority were taking antiretroviral therapy (19/24 included studies). The exercise intervention included aerobic exercise alone (11 studies) or a combination of aerobic and resistive exercise (13 studies) ranging from 5 to 52 weeks. Fifty-eight meta-analyses were performed. Main results indicated statistically significant improvements in selected outcomes of cardiorespiratory status (maximum oxygen consumption, exercise time), strength (chest press, knee flexion), body composition (lean body mass, percent body fat, leg muscle area), depression symptoms, and quality of life (SF-36 questionnaire) among exercisers compared with non-exercisers. No significant differences in change in CD4 count and viral load were found.ConclusionsPerforming aerobic exercise or a combination of aerobic and resistive exercise at least three times per week for at least five weeks is safe and can lead to improvements in cardiorespiratory fitness, strength, body composition and quality of life for adults with HIV. Aerobic exercise is safe and beneficial for adults living with HIV who are medically stable.Electronic supplementary materialThe online version of this article (doi:10.1186/s12879-016-1478-2) contains supplementary material, which is available to authorized users.

Health inequities are widespread and persistent, and the root causes are social, political and economic as opposed to exclusively behavioural or genetic. A barrier to transformative change is the tendency to frame these inequities as unfair consequences of social structures that result in disadvantage, without also considering how these same structures give unearned advantage, or privilege, to others. Eclipsing privilege in discussions of health equity is a crucial shortcoming, because how one frames the problem sets the range of possible solutions that will follow. If inequity is framed exclusively as a problem facing people who are disadvantaged, then responses will only ever target the needs of these groups without redressing the social structures causing disadvantages. Furthermore, responses will ignore the complicity of the corollary groups who receive unearned and unfair advantage from these same structures. In other words, we are missing the bigger picture. In this conceptualization of health inequity, we have limited the potential for disruptive action to end these enduring patterns.The goal of this article is to advance understanding and action on health inequities and the social determinants of health by introducing a framework for transformative change: the Coin Model of Privilege and Critical Allyship. First, I introduce the model, which explains how social structures produce both unearned advantage and disadvantage. The model embraces an intersectional approach to understand how systems of inequality, such as sexism, racism and ableism, interact with each other to produce complex patterns of privilege and oppression. Second, I describe principles for practicing critical allyship to guide the actions of people in positions of privilege for resisting the unjust structures that produce health inequities. The article is a call to action for all working in health to (1) recognize their positions of privilege, and (2) use this understanding to reorient their approach from saving unfortunate people to working in solidarity and collective action on systems of inequality.

This systematic review examined the effectiveness and safety of progressive resistive exercise (PRE) interventions on immunological/virological, cardiopulmonary, weight, and body composition, strength and psychological outcomes in adults living with HIV. Using Cochrane Collaboration protocol, we included randomized controlled trials from 1980-2006 comparing PRE interventions with no PRE or another intervention. Ten studies met inclusion criteria. Seventeen meta-analyses were performed. Results indicated that PRE or a combination of PRE and aerobic exercise may lead to statistically significant increases in weight (WMD: 2.68 kg; 95%CI: 0.40, 4.97) and arm and thigh girth (WMD: 7.91 cm; 95%CI: 2.18, 13.65) among exercisers versus non-exercisers. Trends toward improvement in submaximum heart rate and exercise time also were found. Individual studies suggested that PRE contributed to improved strength and psychological status. Findings are limited to participants who continued to exercise. Progressive resistive exercise appears to be safe and may be beneficial for medically-stable adults living with HIV.

In industrialized countries where HIV infection is becoming a chronic, episodic condition, rehabilitation services have the potential to play an expanded role for people living with HIV/AIDS (PLHAs). However, little is known about rehabilitation in the context of HIV. This paper documents the development of an enhanced, multidisciplinary conceptual framework of rehabilitation in the context of HIV, using the perceptions of PLHAs and rehabilitation professionals. Rehabilitation, broadly defined, is a dynamic process that includes all prevention and/or treatment activities and/or services that address body impairments, activity limitations and participation restrictions for an individual. The framework was developed through broad consultation and interviews with thirteen key informants. Themes that emerged from analysis of interviews related to concepts of rehabilitation in the context of HIV, rehabilitation professionals' roles in the context of HIV, and barriers to access and delivery of rehabilitation services. While there was some variation, key informants generally viewed rehabilitation as a goal-oriented and client-centered process with the potential to impact a range of life domains. Themes were presented to members of a national advisory committee (including PLHAs and health care providers), who produced the foundation of the HIV rehabilitation framework. The framework uses the perspective of the person living with HIV/AIDS, and includes individual life domains that may be affected by HIV, drawing and expanding upon the World Health Organization's (WHO's) International Classification of Functioning, Disability and Health.

Health promotion researchers are increasingly conducting Community-Based Participatory Research in an effort to reduce health disparities. Despite efforts towards greater inclusion, research teams continue to regularly exclude diverse representation from data analysis efforts. The DEPICT model for collaborative qualitative analysis is a democratic approach to enhancing rigour through inclusion of diverse stakeholders. It is broken down into six sequential steps. Strong leadership, coordination and facilitation skills are needed; however, the process is flexible enough to adapt to most environments and varying levels of expertise. Including diverse stakeholders on an analysis team can enrich data analysis and provide more nuanced understandings of complicated health problems.

BackgroundThe ongoing role of colonialism in producing health inequities is well-known. Postcolonialism is a theoretical approach that enables healthcare providers to better understand and address health inequities in society. While the importance of postcolonialism and health (PCH) in the education of clinicians has been recognized, the literature lacks guidance on how to incorporate PCH into healthcare training programs. This study explores the perspectives of key informants regarding content related to PCH that should be included in Canadian healthcare training programs, and how this content should be delivered.MethodsThis qualitative study involved in-depth, semi-structured interviews with nineteen individuals with insight into PCH in Canada. Data were analyzed collaboratively to identify, code and translate key emergent themes according to the six phases of the DEPICT method.ResultsThree themes emerged related to incorporating PCH into Canadian healthcare training programs: (1) content related to PCH that should be taught; (2) how this content should be delivered, including teaching strategies, who should teach this content and when content should be taught, and; (3) why this content should be taught. For the Canadian context, participants advised that PCH content should include a foundational history of colonization of Aboriginal Peoples in Canada, how structures rooted in colonialism continue to produce health inequities, and how Canadian clinicians’ own experiences of privilege and oppression affect their practice. Participants also advised that this content should be integrated longitudinally through a variety of interactive teaching strategies and developed in collaboration with Aboriginal partners to address health inequities.ConclusionsThese findings reinforce that clinicians and educators must understand health and healthcare as situated in social, political and historical contexts rooted in colonialism. Postcolonialism enables learners to understand and respond to how colonialism creates and sustains health inequities. This empirical study provides educators with guidance regarding PCH content and delivery strategies for healthcare training programs. More broadly, this study joins the chorus of voices calling for critical reflection on the limits and harms of an exclusively Western worldview, and the need for action to name and correct past wrongs in the spirit of reconciliation and justice for all.

BackgroundHIV is increasingly considered a chronic illness. More individuals are living longer and aging with the health-related consequences associated with HIV and multi-morbidity. Exercise is a self-management approach that can promote health for people aging with HIV. We examined the safety and effectiveness of progressive resistive exercise (PRE) interventions on immunological, virological, cardiorespiratory, strength, weight, body composition, and psychological outcomes in adults living with HIV.MethodsWe conducted a systematic review using the Cochrane Collaboration protocol. Searching databases up to April 2013, we included randomized controlled trials that compared PRE with no exercise or another intervention performed at least three times per week for at least four weeks with adults living with HIV. Two reviewers independently determined study eligibility. We extracted data from included studies and assessed risk of bias using the Cochrane Collaboration risk of bias tool. Meta-analyses were conducted using random effects models with Review Manager (RevMan) computer software.ResultsTwenty studies met inclusion criteria (n = 764 participants at study completion); the majority of participants were men (77%) taking antiretroviral therapy (14/20 included studies). Exercise interventions included PRE alone (8 studies) or a combination of resistive and aerobic exercise (12 studies) ranging from 6 to 52 weeks in duration. Thirty-four meta-analyses were performed. Results demonstrated statistically significant improvements in cardiorespiratory status (maximum oxygen consumption, exercise time), strength (chest press, knee flexion), weight, and body composition (arm and thigh girth, leg muscle area) among exercisers versus non-exercisers. We found no significant differences in change in CD4 count and viral load. We were unable to perform meta-analyses for psychological outcomes however results from individual studies demonstrated improvements in health-related quality of life with exercisers compared with non-exercisers.ConclusionsPerforming progressive resistive exercise (PRE) or a combination of resistive and aerobic exercise at least three times per week for at least six weeks is safe and can lead to improvements in cardiorespiratory fitness, strength, weight, and body composition for adults with HIV. Exercise may be considered a safe and beneficial for enhancing the health of medically stable adults aging with HIV.Electronic supplementary materialThe online version of this article (doi:10.1186/s12879-017-2342-8) contains supplementary material, which is available to authorized users.
