Substance Use Patterns Among Women Living with HIV Compared with the General Female Population of Canada

BACKGROUND: HIV infection and substance use synergistically impact health outcomes of people with HIV. In this study, we assessed the prevalence of substance use among women living with HIV (WLWH) and compared them with expected values from general data. METHODS: Cigarette smoking, frequency of alcohol consumption, last-month non-prescribed cannabis use (vs. last-year use), and last 3 months regular (≥once/week) and occasional ( RESULTS: Compared to expected estimates from general population women, a higher proportion of WLWH reported daily cigarette smoking (SPD: 26.8% [95% CI: 23.9, 29.7]), smoking ≥20 cigarettes/day (SPD: 11.6% [9.8, 13.6]), regular non-prescribed cannabis use (SPD: 8.0% [4.1, 8.6]), regular crack/cocaine use (SPD: 16.7% [13.1, 20.9]), regular/occasional speed use (SPD: 2.4% [1.2, 4.7]), and heroin use (SPD: 11.2% [8.3, 15.0]). However, WLWH reported lower frequencies of alcohol consumption and binge drinking than their counterparts in the general population. CONCLUSIONS: Cigarette smoking and illicit drug use, but not alcohol use or binge drinking, were more prevalent in WLWH than would be expected for Canadian women with a similar age and ethnoracial group profile. These findings may indicate the need for women-centered harm reduction programs to improve health outcomes of WLWH in Canada

Patterns of social determinants of health associated with drug use among women living with HIV in Canada: a latent class analysis

Background and AimsIdentifying typologies of social determinants of health (SDoH) vulnerability influencing drug use practices among women living with HIV (WLWH) can help to address associated harms. This research aimed to explore the association of SDoH clusters with drug use among WLWH.DesignLatent class analysis (LCA) was used to identify the distinct clusters of SDoH. Inverse probability weighting (IPW) was employed to account for confounding and potential selection bias. Associations were analyzed using generalized linear model with log link and Poisson distribution, and then weighted risk ratio (RR) and 95% confidence intervals (CI) were reported.Setting and ParticipantsData from 1422 WLWH recruited at timeâ point 1 of the Canadian HIV Women’s Sexual and Reproductive Health Cohort Study (CHIWOS, 2013â 15), with 1252 participants at 18 months followâ up (timeâ point 2).MeasurementsDrug use was defined as use of illicit/nonâ prescribed opioids/stimulants in the past 6 months. SDoH indicators included: race discrimination, gender discrimination, HIV stigma, social support, access to care, food security, income level, employment status, education, housing status and histories of recent sex work and incarceration.FindingsLCA identified four SDoH classes: no/least SDoH adversities (6.6%), discrimination/stigma (17.7%), economic hardship (30.8%) and most SDoH adversities (45.0%). Drug use was reported by 17.5% and 17.2% at timeâ points 1 and 2, respectively. WLWH with no/least SDoH adversities were less likely to report drug use than those in economic hardship class (weighted RR = 0.13; 95% CIs = 0.03, 0.63), discrimination/stigma class (weighted RR = 0.15; 95% CIs = 0.03, 0.78), and most SDoH adversities class (weighted RR = 0.13; 95% CIs = 0.03, 0.58).ConclusionsSocial determinants of health vulnerabilities are associated with greater likelihood of drug use, underscoring the significance of addressing interlinked social determinants and drug use through the course of HIV care and treatment.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/149504/1/add14566_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/149504/2/add14566.pd

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

Understanding access to HIV-related and gender-affirming healthcare for trans women with HIV in Canada: A mixed methods study

Background: Trans women living with HIV (WLWH) have lower access to HIV care compared to cisgender (cis) people living with HIV. US-based research describes barriers (e.g., trans stigma) and facilitators (e.g., integration of gender-affirming and HIV care) to HIV care engagement among trans WLWH. Scant research has explored factors associated with HIV or gender-affirming care access among trans WLWH in Canada. This three-paper dissertation aims to expand an intersectional and social ecological understanding of the experiences of trans WLWH in Canada accessing HIV, gender-affirming, and other types of healthcare. Methods: A transformative, convergent parallel, mixed methods design was used whereby quantitative and qualitative data were rigorously collected and analyzed, then purposefully merged. Quantitative data was drawn from baseline cross-sectional survey data collected 2013-2015 from the Canadian HIV Women’s Sexual and Reproductive Health Cohort Study (CHIWOS) (n=54 trans WLWH/n=1422 participants) and analyzed using descriptive statistics and bivariate analyses. In-depth semi-structured individual interviews (25-100 minutes) were conducted with a purposive sub-set of trans WLWH (n=11) 2017-2018 who completed the baseline CHIWOS survey, analyzed using framework analysis. Qualitative and quantitative results were merged by comparing data and considering how results converged, diverged, or expanded understanding. Inequities were highlighted and recommendations made, consistent with a transformative design. Results: Three empirically-based chapters report on: (1) the HIV care cascade and factors associated with HIV care cascade outcomes (ever accessed HIV care, received any HIV care in the past year, currently use antiretroviral treatment (ART), ART adherence, and virological suppression); (2) transition and gender-affirming healthcare experiences of trans WLWH; and (3) resilience and empowerment exhibited by trans WLWH as they navigate intersecting stigmas in healthcare settings. Conclusions: Findings suggest a need for multi-level interventions to address barriers to accessing care. Intersecting stigmas were a pervasive barrier to accessing multiple types of healthcare. Trans WLWH resist and reduce stigma in healthcare settings; however, widespread stigma-reduction training for providers, administrators, and students is recommended. These findings inform a trajectory of social work research, theory development, and practice at policy, organizational, and individual levels, all of which may further contribute to health equity for trans WLWH in Canada.Ph.D.2020-11-19 00:00:0

Correlates of clinical breast examination among lesbian, gay, bisexual, and queer women

OBJECTIVES: Lesbian, gay, bisexual, and queer (LGBQ) women have increased risk of breast cancer yet lower use of early detection screening than heterosexual women. This lower use may be due in part to sexual stigma. The study purpose was to explore correlates of past two-year clinical breast examination (CBE) among LGBQ women to better understand screening disparities, particularly among gender non-conforming LGBQ women. METHODS: A cross-sectional Internet-based survey was conducted with LGBQ women in 2011–2012. We conducted multivariate logistic regression to assess the associations between individual, social/structural and health care factors and past two-year CBE among LGBQ women (n = 414), including a subsample of gender non-conforming LGBQ women (n = 148). RESULTS: In multivariate analyses, significant correlates of past two-year CBE among the full sample included sexually transmitted infection knowledge (OR: 1.12, 95% CI: 1.05, 1.19), sexual risk practices (OR: 0.92, 95% CI: 0.87, 0.98), past two-year Papanicolaou test (OR: 8.36, 95% CI: 4.24, 16.45), having a regular source of health care (OR: 4.84, 95% CI: 2.60, 9.01), and health care provider knowing one’s sexual orientation (OR: 3.60, 95% CI: 2.29, 5.81). Among gender non-conforming LGBQ women, perceived gender non-conformity stigma (OR: 0.85, 95% CI: 0.74, 0.99) and belief that one’s health care provider is uncomfortable with one’s sexual orientation (OR: 0.33, 95% CI: 0.11, 1.00) were also associated with lower screening. CONCLUSION: These findings enhance understanding of individual, social/structural, and health care factors correlated with CBE among LGBQ women. More research is needed to understand the complex interplay of these factors to inform multi-level interventions to address screening disparities for diverse LGBQ women

Taking culture seriously in biomedical HIV prevention trials: a meta-synthesis of qualitative studies

This is an Accepted Manuscript of an article published by Taylor & Francis in the American Journal of Bioethics in 2016, available at http://www.tandfonline.com/doi/full/10.1586/14760584.2016.1118349From publisher: A substantial gap exists between widespread acknowledgement of the importance of incorporating cultural sensitivity in biomedical HIV prevention trials and empirical evidence to guide the operationalization of cultural sensitivity in these trials. We conducted a systematic literature search and qualitative meta-synthesis to explore how culture is conceptualized and operationalized in global biomedical HIV prevention trials. Across 29 studies, the majority (n = 17) were conducted in resource-limited settings. We identified four overarching themes: (1) semantic cultural sensitivity – challenges in communicating scientific terminology into local vernaculars; (2) instrumental cultural sensitivity – understanding historical experiences to guide tailoring of trial activities; (3) budgetary, logistical, and personnel implications of operationalizing cultural sensitivity; and (4) culture as an asset. Future investigations should address how sociocultural considerations are operationalized across the spectrum of trial preparedness, implementation, and dissemination in particular sociocultural contexts, including intervention studies and evaluations of the effectiveness of methods used to operationalize culturally sensitive practices.PA Newman is principal investigator on studies funded by the Canadian Institutes of Health Research (THA-118570), and receives funding from the Canada Research Chairs Program

Examining TikTok’s Potential for Community-Engaged Digital Knowledge Mobilization With Equity-Seeking Groups

Social media is increasingly being leveraged by researchers to engage in public debates and rapidly disseminate research results to health care providers, health care users, policy makers, educators, and the general public. This paper contributes to the growing literature on the use of social media for digital knowledge mobilization, drawing particular attention to TikTok and its unique potential for collaborative knowledge mobilization with underserved communities who experience barriers to health care and health inequities (eg, equity-seeking groups). Setting the TikTok platform apart from other social media are the unique audiovisual video editing tools, together with an impactful algorithm, that make knowledge dissemination and exchange with large global audiences possible. As an example, we will discuss digital knowledge mobilization with trans and nonbinary (trans) communities, a population that experiences barriers to health care and is engaged in significant peer-to-peer health information sharing on the web. To demonstrate, analytics data from 13 selected TikTok videos on the topic of research on gender-affirming medicine (eg, hormonal therapy and surgeries) are presented to illustrate how knowledge is disseminated within the trans community via TikTok. Considerations for researchers planning to use TikTok for digital knowledge mobilization and other related community engagement with equity-seeking groups are also discussed. These include the limitations of TikTok analytics data for measuring knowledge mobilization, population-specific concerns related to community safety on social media, the spread of disinformation, barriers to internet access, and commercialization and intellectual property issues. This paper concludes that TikTok is an innovative social media platform that presents possibilities for achieving transformative, community-engaged knowledge mobilization among researchers, underserved health care users, and their health care providers, all of whom are necessary to achieve better health care and population health outcomes
