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.
H omeless and vulnerably housed populations are heterogeneous 1 and continue to grow in numbers in urban and rural settings as forces of urbanization collide with gentrification and austerity policies. 2 Collectively, they face dangerous living conditions and marginalization within health care systems. 3 However, providers can improve the health of people who are homeless or vulnerably housed, most powerfully by following evidence-based initial steps, and working with communities and adopting anti-oppressive practices. 1,4,5 Broadly speaking, "homelessness" encompasses all individuals without stable, permanent and acceptable housing, or lacking the immediate prospect, means and ability of acquiring it. 6 Under such conditions, individuals and families face intersecting social, mental and physical health risks that significantly increase morbidity and mortality. 7,8 For example, people who are homeless and vulnerably housed experience a significantly higher prevalence of trauma, mental health conditions and substance use disorders than the general population. 7,9 Canadian research reports that people who experience homelessness face life expectancies as low as 42 years for men and 52 years for women. 7 A generation ago, homeless Canadians were largely middleaged, single men in large urban settings. 10 Today, the epidemiology has shifted to include higher proportions of women, youth, Indigenous people (Box 1), immigrants, older adults and people from rural communities. 13,14 For example, family homelessness (and therefore homelessness among dependent children and youth) is a substantial, yet hidden, part of the crisis. 15 In 2014, of the estimated 235 000 homeless people in Canada, 27.3% were women, 18.7% were youth, 6% were recent immigrants or migrants, and a growing number were veterans and seniors. 10
Our goal was to determine whether introducing rapid point-of-care (POC) whole-blood HIV testing as alternative to standard laboratory-based testing is acceptable and changes the rate of receiving test results at an anonymous testing program. From December 2001 through April 2002 all patients requesting HIV testing at Hassle Free Clinic in Toronto were offered rapid POC or standard testing. Routine clinical data was collected. All patients were invited to complete a questionnaire evaluating testing procedure. Test counselors also completed evaluation questionnaires. HIV-positive patients were invited to an in-depth interview. There were 1610 patients, 91% chose the rapid POC test. Overall 98.9% of patients received final results, compared with 93% in the previous year. Among the rapid testers, 100% received an initial result, and 18 of 22 testing positive returned for confirmatory results. Among standard testers 90.8% returned for results (p < 0.001 compared to rapid testers) including all of the 4 with positive tests. There were 1257 (79%) patients who completed questionnaires, 4 with positive tests agreed to interviews, and test counselors evaluated every visit. Standard testers indicated significantly greater difficulty than rapid testers with the testing procedure. Test counselors also indicated that standard testers had greater difficulty. HIV-positive patients coped well with the testing procedure and indicated high quality counseling was important. Rapid HIV testing was acceptable to patients and test counselors, provided more patients with test results and reduced total time and number of visits. High-quality pretest and posttest counseling is particularly important for rapid testers with positive results. The impact of false-positive results requires further study.
We tested 104 residents and 141 staff for COVID-19 who failed daily symptom screening in homeless shelters in Hamilton, Canada. We detected one resident (1%), seven staff (5%) and one case of secondary spread. Shelter restructuring to allow physical distancing, testing and isolation can decrease outbreaks in shelters.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
