Structural and Environmental Barriers to Condom Use Negotiation With Clients Among Female Sex Workers: Implications for HIV-Prevention Strategies and Policy

摘要

Objectives. We investigated the relationship between environmental-structural factors and condom-use negotiation with clients among female sex workers.Methods. We used baseline data from a 2006 Vancouver, British Columbia, community-based cohort of female sex workers, to map the clustering of "hot spots" for being pressured into unprotected sexual intercourse by a client and assess sexual HIV risk. We used multivariate logistic modeling to estimate the relationship between environmental-structural factors and being pressured by a client into unprotected sexual intercourse.Results. In multivariate analyses, being pressured into having unprotected sexual intercourse was independently associated with having an individual zoning restriction (odds ratio [OR] =3.39; 95% confidence interval [Cl] = 1.00, 9.36), working away from main streets because of policing (OR = 3.01; 95% Cl = 1.39,7.44), borrowing a used crack pipe (OR = 2.51; 95% Cl = 1.06,2.49), client-perpetrated violence (OR = 2.08; 95% Cl = 1.06, 4.49), and servicing clients in cars or in public spaces (OR=2.00; 95% Cl = 1.65, 5.73).Conclusions. Given growing global concern surrounding the failings of prohibitive sex-work legislation on sex workers' health and safety, there is urgent need for environmental-structural HIV-prevention efforts that facilitate sex workers' ability to negotiate condom use in safer sex-work environments and criminalize abuse by clients and third parties.
