The impact of a stress management intervention including cultural components on stress biomarker levels and mental health indicators among indigenous women.

We examined the effectiveness of a 26-week culture-inclusive intervention on reducing salivary stress biomarker levels, and perceived stress, depressive, and post-traumatic stress disorder (PTSD) symptoms measured using scales in 53 Indigenous women in Ontario, Canada. Statistical analyses compared the average biomarker levels, and the area under the curve (AUC) of biomarkers. Differences in biomarkers and mental health scale scores pre- and post-intervention were compared using mixed models with a random intercept. Interaction terms were included between the intervention and age, education, disability, and HIV status, individually, to test for sub-group differences. Cortisol AUC post-intervention was decreased compared to pre-intervention (ß -1.29 µg/dL; 95%CI -2.35, -0.23). There was a slight decrease in perceived stress levels (aOR: -2.80; 95%CI -5.09, -0.50). The associations were stronger among women of younger age, higher education, and no disabilities. These interventions can be effective, but future interventions should target Indigenous population sub-groups to address individual needs.

Low human papillomavirus vaccine uptake among women engaged in HIV care in Ontario, Canada.

Women living with HIV are at higher risk for human papillomavirus (HPV)-related dysplasia and cancers and thus are prioritized for HPV vaccination. We measured HPV vaccine uptake among women engaged in HIV care in Ontario, Canada, and identified socio-demographic, behavioural, and clinical characteristics associated with HPV vaccination. During annual interviews from 2017 to 2020, women participating in a multi-site, clinical HIV cohort responded to a cross-sectional survey on HPV vaccine knowledge and receipt. We used logistic regression to derive age-adjusted odds ratios and 95% confidence intervals (CI) for factors associated with self-reported vaccine initiation (≥1 dose) or series completion (3 doses). Among 591 women (median age = 48 years; interquartile range = 40-56 years), 13.2% (95%CI = 10.5-15.9%) had received ≥1 dose. Of those vaccinated, 64.6% had received 3 doses. Vaccine initiation (≥1 dose) was significantly higher among women aged 20-29 years at 31.0% but fell to 13.9% in those aged 30-49 years and < 10% in those aged ≥50 years. After age adjustment, vaccine initiation was significantly associated with being employed (vs. unemployed but seeking work), income $40,000-$59,999 (vs. <$20,000), being married/common-law (vs. single), living with children, immigrating to Canada >5 years ago (vs. immigrating ≤5 years ago), never smoking (vs. currently smoking), and being in HIV care longer (per 10 years). Similar factors were identified for series completion (3 doses). HPV vaccine uptake remains low among women living with HIV in our cohort despite regular engagement in care. Recommendations for improving uptake include education of healthcare providers, targeted community outreach, and public funding of HPV vaccination.

Systematic review of Indigenous involvement and content in mental health interventions and their effectiveness for Indigenous populations.

OBJECTIVE: To assess the effects of psychological, psychosocial, educational and alternative interventions on mental health outcomes of Indigenous adult populations in Australia, Canada, New Zealand and the United States and the Indigenous involvement and content in each study. METHODS: We systematically searched databases, key journals and gray literature, for records until June 2020. Eligible studies were in English or French and examined the impact of interventions on mental health outcomes including anxiety disorders, posttraumatic stress disorder, depression, psychological distress or stress for Indigenous adults (⩾16 years). Data were extracted using a modified Cochrane Data Extraction Form and the Template for Intervention Description and Replication. Quality was evaluated using the Effective Public Health Practice Project quality assessment form. RESULTS: In total, 21 studies were eligible, comprising 8 randomized controlled trials, 10 single-group pre-post studies and 3 pre-post studies with comparison groups. Twenty studies had Indigenous individuals or organizations involved in some decision-making capacity, though extent of involvement varied widely. In total, 9 studies were rated moderate and 12 weak in the Effective Public Health Practice Project quality assessment. Eight studies measuring depression, three measuring posttraumatic stress disorder, three measuring psychological distress and two measuring stress showed statistically significant improvements following the intervention. CONCLUSION: A wide range of interventions demonstrated mental health improvements. However, it is difficult to draw generalizable conclusions on intervention effectiveness, given heterogeneity among studies. Studies should employ a thorough assessment of the Indigenous involvement and content of their interventions for reporting and for critical consideration of the implications of their research and whether they address Indigenous determinants of mental health.

Hiring, training, and supporting Peer Research Associates: Operationalizing community-based research principles within epidemiological studies by, with, and for women living with HIV.

BACKGROUND: A community-based research (CBR) approach is critical to redressing the exclusion of women-particularly, traditionally marginalized women including those who use substances-from HIV research participation and benefit. However, few studies have articulated their process of involving and engaging peers, particularly within large-scale cohort studies of women living with HIV where gender, cultural and linguistic diversity, HIV stigma, substance use experience, and power inequities must be navigated. METHODS: Through our work on the Canadian HIV Women's Sexual and Reproductive Health Cohort Study (CHIWOS), Canada's largest community-collaborative longitudinal cohort of women living with HIV (n = 1422), we developed a comprehensive, regionally tailored approach for hiring, training, and supporting women living with HIV as Peer Research Associates (PRAs). To reflect the diversity of women with HIV in Canada, we initially hired 37 PRAs from British Columbia, Ontario, and Quebec, prioritizing women historically under-represented in research, including women who use or have used illicit drugs, and women living with HIV of other social identities including Indigenous, racialized, LGBTQ2S, and sex work communities, noting important points of intersection between these groups. RESULTS: Building on PRAs' lived experience, research capacity was supported through a comprehensive, multi-phase, and evidence-based experiential training curriculum, with mentorship and support opportunities provided at various stages of the study. Challenges included the following: being responsive to PRAs' diversity; ensuring PRAs' health, well-being, safety, and confidentiality; supporting PRAs to navigate shifting roles in their community; and ensuring sufficient time and resources for the translation of materials between English and French. Opportunities included the following: mutual capacity building of PRAs and researchers; community-informed approaches to study the processes and challenges; enhanced recruitment of harder-to-reach populations; and stronger community partnerships facilitating advocacy and action on findings. CONCLUSIONS: Community-collaborative studies are key to increasing the relevance and impact potential of research. For women living with HIV to participate in and benefit from HIV research, studies must foster inclusive, flexible, safe, and reciprocal approaches to PRA engagement, employment, and training tailored to regional contexts and women's lives. Recommendations for best practice are offered.

Teenage pregnancy and long-term mental health outcomes among Indigenous women in Canada.

Our objectives were to (1) compare the risks for poor long-term mental health outcomes among indigenous women with and without a teenage pregnancy and (2) determine if community and cultural factors modify this risk. We conducted a secondary analysis of the 2012 Aboriginal Peoples Survey. Respondents were women aged 25 to 49 years who had given birth to at least one child. Teenage mothers (age at first birth 13 to 19 years; n = 1330) were compared to adult mothers (age at first birth 20 years or older; n = 2630). Mental health outcomes were psychological distress, mental health status, suicide ideation/attempt, and alcohol consumption. To address objective 1, we used binary logistic regression analyses before and after controlling for covariates. To address objective 2, we tested the significance of interaction terms between teenage pregnancy status and effect measure modifiers. In unadjusted analyses, teenage pregnancy was associated with increased risk for poor/fair mental health [odds ratio (OR) 1.77, 95% confidence interval (CI) 1.24-2.53] and suicide attempt/ideation (OR 1.95, 95% CI 1.07-3.54). However, the associations were not statistically significant after adjusting for demographic, socioeconomic, environmental, and health covariates. Teenage pregnancy was not associated with increased risk for high psychological distress or heavy alcohol consumption in unadjusted or adjusted analyses. The interaction term for involvement in cultural activities was statistically significant for poor/fair mental health; however, after stratification, ORs were non-significant. Among indigenous mothers, teenage pregnancy was less important than broader social and health circumstances in predicting long-term mental health.

Social determinants of health and retention in HIV care in a clinical cohort in Ontario, Canada.

Continuous HIV care supports antiretroviral therapy initiation and adherence, and prolongs survival. We investigated the association of social determinants of health (SDH) and subsequent retention in HIV care in a clinical cohort in Ontario, Canada. The Ontario HIV Treatment Network Cohort Study is a multi-site cohort of patients at 10 HIV clinics. Data were collected from medical charts, interviews, and via record linkage with the provincial public health laboratory for viral load tests. For participants interviewed in 2009, we used three-category multinomial logistic regression to identify predictors of retention in 2010-2012, defined as (1) continuous care (≥2 viral loads ≥90 days in all years; reference category); (2) discontinuous care (only 1 viral load/year in ≥1 year); and (3) a gap in care (≥1 year in 2010-2012 with no viral load). In total, 1838 participants were included. In 2010-2012, 71.7% had continuous care, 20.9% had discontinuous care, and 7.5% had a gap in care. Discontinuous care in 2009 was predictive (p < .0001) of future retention. SDH associated with discontinuous care were Indigenous ethnicity, being born in Canada, being employed, reporting hazardous drinking, and non-injection drug use. Being a heterosexual male was associated with having a gap in care, and being single and younger were associated with discontinuous care and a gap in care. Various SDH were associated with retention. Care discontinuity was highly predictive of future gaps. Targeted strategic interventions that better engage those at risk of suboptimal retention merit exploration.

Time to Viremia for Patients Taking their First Antiretroviral Regimen and the Subsequent Resistance Profiles.

BACKGROUND: The resistance profiles for patients on first-line antiretroviral therapy (ART) regimens after viremia have not been well studied in community clinic settings in the modern treatment era. OBJECTIVE: To determine time to viremia and the ART resistance profiles of viremic patients. METHODS: HIV-positive patients aged ≥16 years initiating a three-drug regimen were retrospectively identified from 01/01/06 to 12/31/12. The regimens were a backbone of two nucleoside reverse transcriptase inhibitors (NRTIs) and a third agent: a protease inhibitor (PI), non-nucleoside reverse transcriptase inhibitor (NNRTI), or an integrase inhibitor (II). Time to viremia was compared using a proportional hazards model, adjusting for demographic and clinical factors. Resistance profiles were described in those with baseline and follow-up genotypes. RESULTS: For 653 patients, distribution of third-agent use and viremia was: 244 (37%) on PIs with 80 viremia, 364 (56%) on NNRTIs with 84 viremia, and 45 (7%) on II with 11 viremia. Only for NNRTIs, time to viremia was longer than PIs (p = 0.04) for patients with a CD4 count ≥200 cells/mm(3). Of the 175 with viremia, 143 (82%) had baseline and 37 (21%) had follow-up genotype. Upon viremia, emerging ART resistance was rare. One new NNRTI (Y181C) mutation was identified and three patients taking PI-based regimens developed NRTI mutations (M184 V, M184I, and T215Y). CONCLUSIONS: Time to viremia for NNRTIs was longer than PIs. With viremia, ART resistance rarely developed without PI or II mutations, but with a few NRTI mutations in those taking PI-based regimens, and NNRTI mutations in those taking NNRTI-based regimens.

Comparison of coping strategies and supports between aboriginal and non-aboriginal people living with HIV in Ontario.

Complex historical and cultural factors have contributed to the HIV epidemic among Aboriginal populations in Canada. This study assesses social supports, adaptive and maladaptive coping mechanisms, stress, and mastery of Canadian-born Aboriginal and Canadian-born Caucasian people living with HIV in Ontario and posits that coping and social support are important micro- and meso-level factors associated with the epidemic. This cross-sectional analysis included questionnaire data collected from 2007 to 2011 at HIV clinics in Toronto. Categorical and continuous variables were compared using chi-square and Wilcoxon rank sum tests, respectively. Correlates of social support and coping were determined using univariate and multivariable linear regression. The analysis included 70 Aboriginal and 665 Caucasian participants. Aboriginal participants had lower levels of employment, education, and annual household income. Aboriginal participants reported more overall (7 vs. 4, p = 0.0003), ongoing (4 vs. 2, p = 0.0004), and early childhood (2 vs. 1, p = 0.02) stressors. Maladaptive coping, adaptive coping, and mastery scores were similar between Aboriginal and Caucasian participants. In multivariable analysis, injection drug use and lower education levels were significant correlates of higher maladaptive coping and lower overall support scores. Despite numerous socioeconomic challenges and personal stressors, Aboriginal people living with HIV who are accessing care exhibited comparable coping and mastery scores to Canadian-born Caucasian people living with HIV, suggesting remarkable strengths within Aboriginal people living with HIV and their communities.

Experiences of chronic stress and mental health concerns among urban Indigenous women.

We measured stress, depression and post-traumatic stress disorder (PTSD) levels of urban Indigenous women living with and without HIV in Ontario, Canada, and identified correlates of depression. We recruited 30 Indigenous women living with HIV and 60 without HIV aged 18 years or older who completed socio-demographic and health questionnaires and validated scales assessing stress, depression and PTSD. Descriptive statistics were conducted to summarize variables and linear regression to identify correlates of depression. 85.6 % of Indigenous women self-identified as First Nation. Co-morbidities other than HIV were self-reported by 82.2 % (n = 74) of the sample. High levels of perceived stress were reported by 57.8 % (n = 52) of the sample and 84.2 % (n = 75) had moderate to high levels of urban stress. High median levels of race-related (51/88, IQR 42-68.5) and parental-related stress (40.5/90, IQR 35-49) scores were reported. 82.2 % (n = 74) reported severe depressive symptoms and 83.2 % (n = 74) severe PTSD. High levels of perceived stress was correlated with high depressive symptoms (estimate 1.28 (95 % CI 0.97-1.58), p < 0.001). Indigenous women living with and without HIV reported elevated levels of stress and physical and mental health concerns. Interventions cutting across diverse health care settings are required for improving and preventing adverse health outcomes.

Demographic and clinical factors correlating with high levels of psychological distress in HIV-positive women living in Ontario, Canada.

The concept of psychological distress includes a range of emotional states with symptoms of depression and anxiety and has yet to be reported in HIV-positive women living in Ontario, Canada, who are known to live with contributing factors. This study aimed to determine the prevalence, severity, and correlates of psychological distress among women accessing HIV care participating in the Ontario HIV Treatment Network Cohort Study using the Kessler Psychological Distress Scale (K10). The K10 is a 10-item, five-level response scale. K10 values range from 10 to 50 with values less than or equal to 19 categorized as not clinically significant, scores between 20 and 24 as moderate levels, 25-29 as high, and 30-50 as very high psychological distress. Correlates of psychological distress were assessed using the Pearson's chi-square test and univariate and multivariate logistic regression analysis. Moderate, high, and very high levels of psychological distress were experienced by 16.9, 10.4, and 15.1% of the 337 women in our cohort, respectively, with 57.6% reporting none. Psychological distress levels greater than 19, correlated with being unemployed (vs. employed/student/retired; AOR = 0.33, 95% CI: 0.13-0.83), living in a household without their child/children (AOR = 2.45, 95% CI: 1.33-4.52), CD4 counts < 200 cells/mm(3) (AOR = 2.07, 95% CI: 0.89-4.80), and to a lesser degree an education of some college or less (vs. completed college or higher; AOR=1.71, 95% CI: 0.99-2.95). Age and ethnicity, a priori variables of interest, did not correlate with psychological distress. Findings suggest that socioeconomic factors which shape the demography of women living with HIV in Ontario, low CD4 counts, and losing the opportunity to care for their child/children has a significant relationship with psychological distress. Approaches to manage psychological distress should address and make considerations for the lived experiences of women since they can act as potential barriers to improving psychological well-being.

Looking beyond the individual-The importance of accessing health and cultural services for Indigenous women in Thunder Bay, Ontario.

Access to cultural activities and culturally relevant healthcare has always been significant for achieving holistic Indigenous health and continues to be a key factor in shaping the health journey of Indigenous individuals and communities. Previous research has indicated the importance of cultural practices and services in sustaining cultural identity for Indigenous peoples, which is a major influence on their wellbeing. This study marks the first phase in a project aimed at establishing an Indigenous healing program and uses a qualitative research approach to understand the health and cultural services that Indigenous women want and require in Thunder Bay, Ontario. During interviews, participants (n = 22) answered questions around their understandings of health and wellbeing, and how they are able to incorporate cultural practices into their circle of care. Thematic analysis was performed on interview transcripts, and 4 key themes were identified: 'independence and self-care', 'external barriers to accessing services', 'finding comfort in the familiar' and 'sense of community'. Together these themes illustrate how Indigenous women feel a strong sense of personal responsibility for maintaining their health despite the multiple environmental factors that may act as barriers or supports. Furthermore, the necessity of embedding cultural practices into Indigenous women's circle of care is highlighted by the participants as they describe the mental, spiritual, social, and emotional health benefits of engaging in cultural activities within their community. The findings demonstrate the need for current modes of care to look beyond the individual and consider the impacts that socio-environmental factors have on Indigenous women. To accomplish this, we hope to increase access to health and cultural services through the creation of an Indigenous healing program that can be adequately incorporated into Indigenous women's circle of care if they wish to do so.

'I don't chase drugs as much anymore, and I'm not dead': Client reported outcomes associated with safer opioid supply programs in Ontario, Canada.

INTRODUCTION: The ongoing opioid overdose crisis, which has killed over 30,000 people in Canada since 2016, is driven by the volatility of an unregulated opioid drug supply comprised primarily of fentanyl. The Canadian government has recently funded safer opioid supply (SOS) programs, which include off-label prescriptions of pharmaceutical-grade opioids to high risk individuals with the goal of reducing overdose deaths. METHODS: In 2021, we examined the implementation and adaption of four SOS programs in Ontario. These programs use a primary care model and serve communities experiencing marginalisation. We conducted semi-structured interviews with program clients. We present the results of a thematic analysis with the aim of describing clients' self-reported impact of these programs on their health and well-being. RESULTS: We interviewed 52 clients between June and October 2021 (mean age 47 years, 56% men, 17% self-identified Indigenous, 14% living with HIV). Our results indicate multifaceted pathways to improved self-reported health and well-being among clients including changes to drug use practices, fewer overdoses, reduced criminalised activity, improved trust and engagement in health care, and increased social stability (e.g., housing). DISCUSSION AND CONCLUSION: Most clients reported that the intervention saved their life because of the reduced frequency of overdoses. Findings suggest that SOS programs improved clients' health outcomes and increase opportunities for engagement in health services. Our results provide insight into the mechanisms behind some of the emergent evidence on the impact of safer supply prescribing.

Proximity and density of unconventional natural gas wells and mental illness and substance use among pregnant individuals: An exploratory study in Canada.

BACKGROUND: Hydraulic fracturing (fracking) is a method used to extract unconventional natural gas (UNG). Living near UNG operations has been associated with various health outcomes, but few have explored the association between UNG and mental health and substance use. Our objective was to evaluate the association between metrics of residential UNG well density/proximity and mental illness and substance use among pregnant individuals in Northeastern British Columbia, Canada. METHODS: Individuals who gave birth at the Fort St John hospital between December 30, 2006 and December 29, 2016 (n = 6278) were included in the study. Exposure was determined using inverse distance weighting (IDW) to calculate the density and proximity of UNG wells to the postal code centroid ofindividual's residential address at delivery. Four exposure metrics, categorized by quartiles, were calculated based on 50, 10, 5 and 2.5 km buffer zones around each postal code centroid. Logistic regression was used to separately evaluate associations between IDW quartiles of each metric and diagnosis of depression and anxiety prior to or during pregnancy, and self-reported substance use during pregnancy, controlling for relevant and available confounders. RESULTS: The second and third quartile (Q) of the 10 km IDW were associated with greater odds of depression (Q2: adjusted (aOR) 1.30, 95% (confidence interval) CI 1.03-1.64; Q3: aOR 1.35, 95% CI 1.07-1.70) compared to the first quartile, but not the fourth. Using the 5 km IDW, we observed a suggestive positive association with depression in the second and third quartile (aOR Q2: 1.21, 95% CI 0.96-1.53; aOR Q3: 1.24, 95% CI 0.98-1.57) compared to the first quartile. No statistically significant association was observed using the 2.5 km IDW exposure metric. CONCLUSION: We observed some evidence of greater odds of mental illness prior to or during pregnancy, and substance use during pregnancy in pregnant individuals living in postal codes with increased UNG well density/proximity, although associations were not observed in smaller buffer zones. This study adds to the growing literature on the adverse health outcomes surrounding living in proximity to UNG operations.

Coronavirus disease 2019 vaccine effectiveness among a population-based cohort of people living with HIV.

OBJECTIVE: People with HIV were underrepresented in coronavirus disease 2019 (COVID-19) vaccine clinical trials. We estimated vaccine effectiveness (VE) against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection for the BNT162b2, mRNA-1273, and ChAdOx1 vaccines among a population-based cohort of people with HIV in Ontario, Canada. DESIGN: Test-negative design. METHODS: We identified people with HIV aged ≥19 years who were tested for SARS-CoV-2 by RT-PCR between December 14, 2020 (first availability of COVID-19 vaccines) and November 21, 2021 (pre-Omicron circulation). Outcomes included any infection, symptomatic infection, and COVID-19-related hospitalization/death. We compared the odds of vaccination between test-positive cases and test-negative controls using multivariable logistic regression with adjustment for age, sex, region, calendar time, SARS-CoV-2 test histories, influenza vaccination, comorbidities, and neighborhood-level socio-economic status. VE was derived as (1 - adjusted odds ratio) × 100%. RESULTS: Among 21 023 adults living with HIV, there were 801 (8.3%) test-positive cases and 8,879 (91.7%) test-negative controls. 20.1% cases and 47.8% of controls received ≥1 COVID-19 vaccine dose; among two-dose recipients, 93.4% received ≥1 mRNA dose. Two-dose VE ≥7 days before specimen collection was 82% (95% confidence interval [CI] = 74-87%) against any infection, 94% (95% CI = 82-98%) against symptomatic infection, and 97% (95% CI = 85-100%) against hospitalization/death. Against any infection, VE declined from 86% (95% CI = 77-92%) within 7-59 days after the second dose to 66% (95% CI = -15-90%) after ≥180 days; we did not observe evidence of waning protection for other outcomes. CONCLUSION: Two doses of COVID-19 vaccine offered substantial protection against symptomatic illness and hospitalization/death in people with HIV prior to the emergence of the Omicron variant. Our findings do not support a broad conclusion that COVID-19 VE is lower among people with HIV in populations that, for the most part, are attending HIV care, taking antiretroviral medication, and are virally suppressed.

How is Etuaptmumk/Two-Eyed Seeing characterized in Indigenous health research? A scoping review.

Our scoping review sought to consider how Etuaptmumk or Two-Eyed Seeing is described in Indigenous health research and to compare descriptions of Two-Eyed Seeing between original authors (Elders Albert and Murdena Marshall, and Dr. Cheryl Bartlett) and new authors. Using the JBI scoping review methodology and qualitative thematic coding, we identified seven categories describing the meaning of Two-Eyed Seeing from 80 articles: guide for life, responsibility for the greater good and future generations, co-learning journey, multiple or diverse perspectives, spirit, decolonization and self-determination, and humans being part of ecosystems. We discuss inconsistencies between the original and new authors, important observations across the thematic categories, and our reflections from the review process. We intend to contribute to a wider dialogue about how Two-Eyed Seeing is understood in Indigenous health research and to encourage thoughtful and rich descriptions of the guiding principle.

Indigenizing our research: indigenous community leadership in HIV epidemiology research.

The use of data intensive health research has allowed for greater understandings of population health. When conducting data intensive health research, engaging and involving the community is essential for conducting meaningful research that is responsive to the public's needs. Particularly, when engaging Indigenous communities in research, there is a need to understand historical and ongoing impacts of colonialism and recognize the strengths in Indigenous Peoples' knowledges and experiences while supporting Indigenous leadership and self-determination in research. This article describes the approach our research team/organization used to engage and involve Indigenous people living with HIV in three research projects using large, linked datasets and looking at HIV outcomes of Indigenous populations in Canada. The foundation of these projects was simultaneously: 1) supporting Indigenous people living with HIV to be involved as research team members, 2) developing research questions to answer with available datasets, and 3) integrating Indigenous and Western ways of knowing. We have identified important considerations and suggestions for engaging and involving Indigenous communities and individuals in the generation of research ideas and analysis of linked data using community-based participatory research approaches through our work. These include engaging stakeholders at the start of the project and involving them throughout the research process, honouring Indigenous ways of knowing, the land, and local protocols and traditions, prioritizing Indigenous voices, promoting co-learning and building capacity, and focusing on developing longitudinal relationships. We describe keys to success and learnings that emerged. Importantly, the methodology practiced and presented in this manuscript is not a qualitative study design whereby research subjects are surveyed about their experiences or beliefs. Rather, the study approach described herein is about engaging people with living experience to co-lead as researchers. Our approach supported Indigenous people to share research that addresses their research priorities and responds to issues relevant to Indigenous Peoples and communities.

Overview of systematic reviews on strategies to improve treatment initiation, adherence to antiretroviral therapy and retention in care for people living with HIV: part 1.

OBJECTIVES: We sought to map the evidence and identify interventions that increase initiation of antiretroviral therapy, adherence to antiretroviral therapy and retention in care for people living with HIV at high risk for poor engagement in care. METHODS: We conducted an overview of systematic reviews and sought for evidence on vulnerable populations (men who have sex with men (MSM), African, Caribbean and Black (ACB) people, sex workers (SWs), people who inject drugs (PWID) and indigenous people). We searched PubMed, Excerpta Medica dataBASE, Cumulative Index to Nursing and Allied Health Literature, PsycINFO, Web of Science and the Cochrane Library in November 2018. We screened, extracted data and assessed methodological quality in duplicate and present a narrative synthesis. RESULTS: We identified 2420 records of which only 98 systematic reviews were eligible. Overall, 65/98 (66.3%) were at low risk of bias. Systematic reviews focused on ACB (66/98; 67.3%), MSM (32/98; 32.7%), PWID (6/98; 6.1%), SWs and prisoners (both 4/98; 4.1%). Interventions were: mixed (37/98; 37.8%), digital (22/98; 22.4%), behavioural or educational (9/98; 9.2%), peer or community based (8/98; 8.2%), health system (7/98; 7.1%), medication modification (6/98; 6.1%), economic (4/98; 4.1%), pharmacy based (3/98; 3.1%) or task-shifting (2/98; 2.0%). Most of the reviews concluded that the interventions effective (69/98; 70.4%), 17.3% (17/98) were neutral or were indeterminate 12.2% (12/98). Knowledge gaps were the types of participants included in primary studies (vulnerable populations not included), poor research quality of primary studies and poorly tailored interventions (not designed for vulnerable populations). Digital, mixed and peer/community-based interventions were reported to be effective across the continuum of care. CONCLUSIONS: Interventions along the care cascade are mostly focused on adherence and do not sufficiently address all vulnerable populations.

Examining the association between stress and antiretroviral therapy adherence among women living with HIV in Toronto, Ontario.

BACKGROUND: We aimed to identify the association between stress and antiretroviral therapy (ART) adherence among women in HIV care in Toronto, Ontario participating in the Ontario HIV Treatment Network Cohort Study (OCS) between 2007 and 2012. MATERIALS AND METHODS: We conducted cross-sectional analyses with women on ART completing the AIDS Clinical Trial Group (ACTG) Adherence Questionnaire. Data closest to, or at the last completed interview, were collected from medical charts, through record linkage with Public Health Ontario Laboratories, and from a standardized self-reported questionnaire comprised of socio-demographic and psycho-socio-behavioral measures (Center for Epidemiologic Studies Depression Scale (CES-D), Alcohol Use Disorders Identification Test (AUDIT)), and stress measures (National Population Health Survey). Logistic regression was used to quantify associations with optimal adherence (≥95% adherence defined as missing ≤ one dose of ART in the past 4 weeks). RESULTS: Among 307 women, 65.5% had optimal adherence. Women with suboptimal compared to optimal adherence had higher median total stress scores (6.0 [interquartile range (IQR): 3.0-8.1] vs. 4.1 [IQR: 2.0-7.1], p = 0.001), CES-D scores (16 [IQR: 6-28] vs. 12 [IQR: 3-22], p = 0.008) and reports of hazardous and harmful alcohol use (31.1% vs. 17.9%, p = 0.008). In our multivariable model, we found an increased likelihood of optimal adherence with the absence of hazardous and harmful alcohol use (Adjusted Odds Ratio (AOR)=2.20, 95% confidence interval (CI): 1.12-4.32) and a decreased likelihood of optimal adherence with more self-reported stress (AOR = 0.56, 95% CI: 0.33-0.94). CONCLUSIONS: Interventions supporting optimal ART adherence should address stress and include strategies to reduce or eliminate hazardous and harmful alcohol use for women living with HIV.

Building Bridges: Describing a Process for Indigenous Engagement in Epidemiology.

BACKGROUND: Processes for epidemiology embedded with Indigenous methodology are needed. Building Bridges was developed to engage Indigenous peoples in epidemiology to address health issues relevant to them. OBJECTIVES: We describe our process for meaningfully engaging Indigenous leaders and peoples living with human immunodeficiency virus (HIV) in epidemiology research. METHODS: As a community-based research (CBR) project, Indigenous methodologies and leadership ensured the quality and relevance of findings. Study phases included 1) advisory board formation, 2) recruitment, 3) research question identification, 4) data analysis from the Canadian HIV Observational Cohort (CANOC) collaboration, 5) data interpretation and contextualization, and 6) knowledge translation and exchange. LESSONS LEARNED: Support and guidance from Indigenous team members, Spiritual Leaders and Elders along with meaningful relationships with allied academic researchers were pivotal. Expertise and lived experiences in Indigenous culture, HIV, epidemiology and services enabled multidirectional learning. CONCLUSIONS: Building Bridges' success hinged on ongoing co-learning and engagement of Indigenous peoples, service providers and researchers.
