Abstract
Background: Due to structural marginalization, sex workers experience health inequities including a high prevalence of sexually transmitted and blood-borne infections, mental health disorders, trauma, and substance use, alongside a multitude of barriers to HIV and substance use services. Given limited evidence on sex workers’ broader primary healthcare access, we aimed to examine structural factors associated with primary care access among sex workers over a 7-year period.
Methods Data were derived from An Evaluation of Sex Workers Health Access (AESHA), a community-based open prospective cohort of women (cis and trans) sex workers in Metro Vancouver, from 2014 to 2021. Descriptive statistics were used to summarize the proportion of primary care use in the past six months and to assess primary care trends over time from 2014-2021. We used multivariate logistic regression with generalized estimating equations (GEE) to identify structural factors associated with primary care access (seeing a family doctor in the last six months), after adjusting for confounders.
Results: Amongst 646 participants, most (87.4%) accessed primary care at some point during the study period, and primary care use in the in the last 6 months was relatively stable (ranging from 60-78%) across each follow-up period. At first available observation, participants faced a high burden of sexually transmitted and blood-borne infections (STBBIs) (48.0%, 11.5%, and 10.4% were HCV, HIV, or STI seropositive, respectively), 56.8% were diagnosed with a mental health disorder, 8.1% had recently overdosed, and 14.7% were recently hospitalized. In multivariable GEE analysis, exposure to intimate partner violence was associated with reduced access to primary care (Adjusted odds ratios (AOR) 0.63, 95% Confidence interval (CI): 0.49 - 0.82), and limited English fluency was marginally associated (AOR 0.76 CI: 0.51 - 1.14).
Conclusions: This study characterized primary care access and its structural determinants among sex workers over 7-years. Participants faced a high burden of STBBIs and other health disparities, and a proportion faced gaps in primary care access. Scale-up of trauma-informed, culturally and linguistically tailored, sex worker-friendly primary care models are needed, alongside structural interventions to decriminalize and destigmatize sex work and substance use.
