Social determinants of health associated with hepatitis C co-infection among people living with HIV: results from the Positive Spaces, Healthy Places study.
Bibliographic record
Abstract
BACKGROUND: Social determinants of health (SDOH) may influence the probability of people living with HIV also being infected with hepatitis C virus (HCV). We compared the SDOH of adults co-infected with HCV/HIV with that of HIV mono-infected adults to identify factors independently associated with HCV infection. METHODS: In this cross-sectional study, face-to-face interviews were conducted with 509 HIV-infected adults affiliated with or receiving services from community-based AIDS service organizations (CBAOs). The primary outcome measure was self-reported HCV infection status. Chi-square, Student's t tests, and Wilcoxon rank-sum tests were performed to compare SDOH of HCV/HIV co-infected participants with that of HIV mono-infected participants. Multivariable hierarchical logistic regression was used to identify factors independently associated with HCV co-infection. RESULTS: Data on 482 (95 HCV/HIV co-infected and 387 HIV mono-infected) adults were analyzed. Compared with participants infected with HIV only, those who were co-infected with HIV and HCV were more likely to be heterosexual, Aboriginal, less educated and unemployed. They were more likely to have a low income, to not be receiving antiretroviral treatment, to live outside the Greater Toronto Area (GTA), to use/abuse substances, experience significant depression, and utilize addiction counselling and needle-exchange services. They also were more likely to report a history of homelessness and perceived housing-related discrimination and to have moved twice or more in the previous 12 months. Factors independently associated with HCV/HIV co-infection were history of incarceration (odds ratio [OR] 8.81, 95% CI 4.43-17.54), history of homelessness (OR 3.15, 95% CI 1.59-6.26), living outside of the GTA (OR 3.13, 95% CI 1.59-6.15), and using/abusing substances in the past 12 months (OR 2.05, 95% CI 1.07-3.91). CONCLUSION: Differences in SDOH exist between HIV/HCV co-infected and HIV mono-infected adults. History of incarceration, history of homelessness, substance use, and living outside the GTA were independently associated with HCV/HIV co-infection. Interventions that reduce homelessness and incarceration may help prevent HCV infection in people living with HIV.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
