Direct and indirect effects of perceived social support on health-related quality of life in persons living with HIV/AIDS

Abstract Research has established a link between perceived social support and health-related quality of life (HRQOL) among persons living with HIV/AIDS. However, little is known about the ways through which social support influences HRQOL. This study examined the direct and indirect effects of perceived social support on physical and mental HRQOL in a sample of 602 adults living with HIV in Ontario, Canada. Participants completed the Medical Outcomes Study-HIV (MOS-HIV) health survey, the MOS-HIV Social Support Scale (MOS-HIV-SSS), and the Center for Epidemiological Studies Depression-Revised scale. Data on demographic and clinical characteristics were also collected. The direct and indirect effects of social support on the two MOS-HIV HRQOL summary measures, that is, physical health summary (PHS) and mental health summary (MHS), were estimated in multiple linear regression analyses. Perceived social support had significant direct effects on PHS (B=0.04, p<0.01) and MHS (B=0.05, p<0.01). It also had significant indirect effect on both PHS (B=0.04, p<0.01) and MHS (B=0.11, p<0.01), mediated by depressive symptoms. Interventions that enhance social support have the potential to contribute to better HRQOL either directly or indirectly by decreasing the deleterious effect of depressive symptoms on HRQOL.

Between skepticism and empowerment: the experiences of peer research assistants in HIV/AIDS, housing and homelessness community‐based research

People living with HIV/AIDS (PHAs) in Canada are a highly researched population, yet their inclusion in the research process is minimal. Community‐based research (CBR) has become a recognized tool for addressing issues of power and exclusion within researcher/community relationships by inviting the communitys equitable involvement as research partners. Within the context of HIV/AIDS research, this includes a commitment to the Greater Involvement of People Living with HIV/AIDS (GIPA) at all stages of the research process. One way of adopting GIPA principles within CBR is through providing employment, research training, and capacity building opportunities for PHAs as peer research assistants (PRAs). Drawing on data from two in‐depth focus groups with seven PRAs from the Positive Spaces, Healthy Places: Community‐based Research Study, this paper will highlight important methodological practices for academic and community‐based researchers who are working with and supporting PRAs.

Under My Umbrella: the housing experiences of HIV positive parents who live with and care for their children in Ontario.

Positive Spaces, Healthy Places (PSHP) is the first longitudinal community-based research (CBR) initiative in Canada to examine housing stability and its relationship to health related quality of life (HRQOL) for people living with of HIV/AIDS (PHAs). As part of our mixed method data collection strategy in-depth, semi-structured interviews were conducted with 50 PHAs across Ontario to provide a deeper understanding of the impact that housing instability has on their mental and physical health. Emerging from the qualitative interviews were the unique issues and concerns that were reported by parents who live with and care for their children. These parents face dire housing, economic and social challenges that are associated with significant risks for poor health outcomes. Poor housing conditions, unsafe neighborhoods, barriers to supports for themselves and their children, HIV related stigma, discrimination, racism, and poverty have been identified by these families as being among their most pressing concerns. This results in increased stress and anxiety that has a negative impact on the mental health of HIV positive parents. In order to more effectively support HIV positive parents and their children, health and social service practices and policies must respond to the unique challenges that face these families.

Housing characteristics and their influence on health-related quality of life in persons living with HIV in Ontario, Canada: results from the positive spaces, healthy places study.

Although lack of housing is linked with adverse health outcomes, little is known about the impacts of the qualitative aspects of housing on health. This study examined the association between structural elements of housing, housing affordability, housing satisfaction and health-related quality of life over a 1-year period. Participants were 509 individuals living with HIV in Ontario, Canada. Regression analyses were conducted to examine relationships between housing variables and physical and mental health-related quality of life. We found significant cross-sectional associations between housing and neighborhood variables—including place of residence, housing affordability, housing stability, and satisfaction with material, meaningful and spatial dimensions of housing—and both physical and mental health-related quality of life. Our analyses also revealed longitudinal associations between housing and neighborhood variables and health-related quality of life. Interventions that enhance housing affordability and housing satisfaction may help improve health-related quality of life of people living with HIV.ResumenA pesar de que la falta de vivienda está vinculada a consecuencias adversas para la salud, conocemos poco sobre el impacto de los aspectos cualitativos de la vivienda sobre la salud. Este estudio examinó la asociación entre elementos estructurales de la vivienda, accesibilidad a la vivienda, satisfacción con la vivienda y la calidad de vida relacionada con la salud (CVRS) por un período de un año. Los participantes fueron 509 personas que viven con el VIH en Ontario, Canada. Análisis de regresión lineal multivariado se llevaron a cabo para examinar la relación entre las variables de vivienda y la calidad de vida relacionada a la salud física y mental. Los resultados de los análisis transversales mostraron una asociación significativa entre las variables de la vivienda y del vecindario - incluyendo lugar de residencia, accesibilidad de precio, la estabilidad de la vivienda y la satisfacción con las dimensiones materiales, de significado y espaciales de la vivienda - y la calidad de vida tanto física como mental. Nuestros análisis también revelaron asociaciones longitudinales entre las variables de vivienda y del vecindario con la CVRS a traves del tiempo. Las intervenciones que mejoran el acceso y la satisfacción con la vivienda pueden ayudar a mejorar la CVRS de las personas que viven con el VIH.

Food insufficiency, housing and health-related quality of life: results from the Positive Spaces, Healthy Places study

Studies of people living with HIV who are homeless or unstably housed show a high prevalence of food insufficiency (>50%) and associated poor health outcomes; however, most evidence is in the form of cross-sectional studies. To better understand this issue, we conducted a longitudinal study to examine the impact of food insufficiency and housing instability on overall physical and mental health-related quality of life (HRQoL) among people living with HIV in Ontario. Six hundred and two adults living with HIV were enrolled in the Positive Spaces, Healthy Places study and followed from 2006 to 2009. Interviewer-administered questionnaires were used, and generalized linear mixed-effects models constructed to examine longitudinal associations between food insufficiency, housing instability and physical and mental HRQoL. At baseline, 57% of participants were classified as food insufficient. After adjusting for potential confounders, longitudinal analyses revealed a significant, negative association between food insufficiency and physical and mental HRQoL outcomes, respectively [effect size (ES) with 95% confidence interval (CI): (ES = −2.1, CI = −3.9,−0.3); (ES = −3.5, CI = −6.1,−1.5)]. Furthermore, difficulties meeting housing costs were shown to have additional negative impacts on mental HRQoL. Food insufficiency is highly prevalent among people living with HIV in Ontario, particularly for those with unstable housing. This vulnerable group of individuals is in urgent need of changes to current housing programmes, services and policies, as well as careful consideration of their unmet nutritional needs.

Not Just “A Roof over Your Head”: The Meaning of Healthy Housing for People Living with HIV

Abstract The literature has identified housing as a fundamental unmet need for people living with HIV; yet there has been little qualitative evidence exploring housing and HIV, particularly from a Canadian context. This paper focuses on our qualitative analyses of the housing experiences of 48 HIV-positive people living in Ontario. Findings from our interviews illustrate healthy housing as a dynamic interconnection between health, housing and other social factors that are influential to the health and well-being of people with HIV. Four salient themes have emerged from our qualitative findings: the interplay between healthy housing and economic security; the relationship between HIV, health and housing precariousness; the interconnection between housing, HIV, safety, stigma, social isolation and social exclusion; and the meaning of healthy housing for people living with HIV. These findings re-emphasize the importance of housing policies that consider housing as more than just a roof over one’s head, but also as something that supports the physical, mental, emotional and social well-being of people living with HIV.

Unmet basic needs negatively affect health-related quality of life in people aging with HIV: results from the Positive Spaces, Healthy Places study

BackgroundBasic needs (e.g., food security and stable housing) are important determinants of health and well-being, yet their impact on health-related quality of life (HRQoL) in the context of HIV and aging has not been systematically investigated.MethodsMultiple linear regression models examined the relationship between unmet basic needs, and physical and mental HRQoL by age strata (20-34, 35-49 and 50+) in a cross-sectional sample of 496 people living with HIV in Ontario, Canada.ResultsAn overwhelming majority of participants (87%) reported unmet needs related to food, clothing or housing. The prevalence of unmet basic needs in the two older groups appeared to be lower than among younger participants, but the difference did not reach statistical significance. The presence of unmet basic needs predicted substantially lower mean physical health and mental health summary scores in the two oldest groups. Notably, age moderated the influence of unmet basic needs on HRQoL.ConclusionsThe availability and accessibility of food security, appropriate clothing and stable housing for people living with HIV who are aging need to become a higher priority for program planners and decision makers.

Elevated Mortality and Associated Social Determinants of Health in a Community-Based Sample of People Living with HIV in Ontario, Canada: Findings from the Positive Spaces, Healthy Places (PSHP) Study

We examined social determinants of health associated with all-cause mortality among 602 people living with HIV/AIDS in Ontario, Canada. Mortality status was verified at 1-, 3-, and 5-year follow-up visits with information obtained from proxies (family members, partners, and friends), obituaries, and local AIDS memorial lists. Of the 454 people for whom mortality information was available, 53 individuals died yielding a crude mortality rate of 22.3 deaths per 1000 person-years, a rate substantially higher than the rate in the general population (6.8 per 1000 population). Experiencing both homelessness and incarceration independently predicted high risk of mortality among men who have sex with men (MSM) while suboptimal self-rated general health at previous visit predicted higher greater risk of mortality in both MSM and women and heterosexual men. Homelessness and incarceration may contribute to HIV disease progression and mortality. Intensive case management that increases retention in care and facilitates linkage to housing services may help to reduce excess deaths among people with HIV.

Needs and Supports in Transitional Housing for People Living with HIV/AIDS in Ontario, Canada

ABSTRACT There is a paucity of research on transitional housing for people living with HIV/AIDS (PHA) and even less so within the Canadian context. The present work addresses that gap and reports on the results from the Transitional Housing Study, a province wide community-based research collaboration involving PHA, service providers, and university researchers in Ontario Canada. This article answers the following research questions: What supports do residents in transitional housing for PHA access and what needs do these supports address? Developing from a thematic analysis of in-depth qualitative interviews with 25 residents in one of three transitional housing agencies in Ontario for PHA, the findings reveal that participants benefited from four key supports while in transitional housing: the provision of a safe environment, co-coordination and management of HIV (and other) drug therapies, assistance with appointments, and referrals to health and social services. Until more resources are available to increase availability of transitional housing for PHA, the nonprofit housing sector must fill the gap that exists by offering the types of supports identified in this study in order to address the needs of PHA. Future research may link these supports efficiently with concrete health improvements and permanent housing stability among PHA.
