Here, we investigate how HIV VL self\u2010reported by women living with HIV enrolled in the British Columbia CARMA\u2010CHIWOS Collaboration Study relates to clinically measured HIV VL. Three HIV\u2010related stigma scales and associations with selected socio\u2010demographic characteristics, such as lifetime history of homelessness, history of substance use, ethnicity, and knowledge about \u2018Undetectable = Untransmittable\u2019, were also examined.<\/jats:p><\/jats:sec>Methods<\/jats:title>For 219 women enrolled between December 2020 and August 2023, self\u2010reported HIV VL<\/jats:styled-content> status (classified as undetectable \u226440 copies\/mL or detectable >40 copies\/mL) was compared with HIV VL<\/jats:styled-content> obtained from chart review closest to, but before the date of self\u2010report (SR). Sensitivity, specificity, predictive values, and likelihood ratios were calculated for the study sample overall and for socio\u2010demographically defined subgroups. Concordance between self\u2010reported HIV VL<\/jats:styled-content> and (CC) clinical chart\u2010derived values was examined by Cohen's kappa. Three HIV<\/jats:styled-content>\u2010related stigma scores were compared between women stratified by the concordance of their self\u2010reported and chart review\u2010based HIV VL<\/jats:styled-content>.<\/jats:p><\/jats:sec>Results<\/jats:title>Ninety\u2010five percent (208\/219) of women were able to estimate their most recent HIV VL<\/jats:styled-content> via self\u2010report, and among them, 96% (200\/208) were on antiretroviral therapy, 50% reported a history of homelessness, and 30% reported current substance use. Overall, the self\u2010reported HIV VL<\/jats:styled-content> was correctly estimated by 189 out of 219, and showed high overall concordance (86%) and moderate agreement (Cohen's kappa\u2009=\u20090.55) with HIV VL<\/jats:styled-content> values derived from CCs. Correctly self\u2010reported undetectable HIV VL<\/jats:styled-content> showed high sensitivity (97.2%) and positive likelihood ratio (1.92), low negative likelihood ratio (0.06), moderate specificity (50%), and performed similarly across socio\u2010demographic subgroups. HIV<\/jats:styled-content> stigma scores did not differ between women who estimated their HIV VL<\/jats:styled-content> correctly versus incorrectly. Of note, knowledge about \u2018Undetectable\u2009=\u2009Untransmittable\u2019 was lower (40%) among women who were not able to estimate their most recent VL<\/jats:styled-content> than among those who did (74%).<\/jats:p><\/jats:sec>Conclusions<\/jats:title>Our findings confirm previous reports of high awareness of HIV VL<\/jats:styled-content> by women in British Columbia, Canada, despite a high prevalence of adverse socio\u2010demographic experiences in this cohort. Our data further suggest that despite highly stigmatized life experiences, women living with HIV<\/jats:styled-content> in British Columbia have a strong awareness of their VL<\/jats:styled-content> status.<\/jats:p><\/jats:sec>","DOI":"10.1111\/hiv.70035","type":"journal-article","created":{"date-parts":[[2025,5,6]],"date-time":"2025-05-06T08:29:01Z","timestamp":1746520141000},"page":"1142-1149","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Self\u2010reported HIV<\/scp> viral load is reliable and not affected by adverse lived experiences of women living with HIV<\/scp> in British Columbia"],"prefix":"10.1111","volume":"26","author":[{"given":"Tetiana","family":"Povshedna","sequence":"first","affiliation":[{"name":"Department of Pathology and Laboratory Medicine University of British Columbia Vancouver British Columbia Canada"},{"name":"Centre for Blood Research University of British Columbia Vancouver British Columbia Canada"},{"name":"Edwin S.H.
