Risk-taking in sex work is related to financial gains from condom-protected and condomless-acts alongside vulnerabilities, including socio-economic factors, which influence the safety of sex workers. Large international sporting events have been shown to significantly impact the economies of host countries, but there is a dearth of studies that examine how major sporting events may affect the economics of sex work and the risks taken by sex workers and clients. This study examines the determinants of the price of commercial sex alongside the price premium for and correlates of, condomless sex before, during and after the 2010 world cup in South Africa. We analysed data from three phases of repeated cross-sectional surveys with sex workers. Bivariate and multivariable logistic regression models were fitted to examine the predictors of condomless sex. We also fitted fixed-effect regression models to examine the determinants of the price of commercial sex across each survey phase. Findings suggest that the price of sex was higher during the world cup compared to before and after, whilst the price premium for condomless-sex increased from 36% before the world cup to 40% (p-value<0.001) and 57% (p-value<0.001) during and after the world cup, respectively. Across the survey phases, anal, oral or masturbation sex were more likely to be supplied without a condom compared to vaginal sex. The type of sex was the primary determinant of the price of sex across all phases. We show indicative evidence that the 2010 world cup was associated with an increase in the price of sex and supply of condomless-sex. Although these findings should be interpreted as associations rather than causal relationships, we recommend that countries with substantial sex-worker populations that host major events shouldexplicitly consider the context and structures of sex work, and promote client-focused safe-sex-interventions that explicitly consider the economic pressures faced by sexworkers to provide riskier acts, to minimise health impacts.
性工作中的冒险行为与有安全套保护和无安全套性行为所带来的经济收益以及包括社会经济因素在内的各种脆弱性相关,这些因素会影响性工作者的安全。大型国际体育赛事已被证明会对主办国的经济产生重大影响,但缺乏研究来探讨重大体育赛事如何影响性工作的经济状况以及性工作者和客户所承担的风险。本研究考察了南非2010年世界杯之前、期间和之后商业性行为价格的决定因素,以及无安全套性行为的价格溢价及其相关因素。我们分析了对性工作者进行的三个阶段重复横断面调查的数据。采用双变量和多变量逻辑回归模型来检验无安全套性行为的预测因素。我们还采用固定效应回归模型来考察每个调查阶段商业性行为价格的决定因素。研究结果表明,与世界杯之前和之后相比,世界杯期间性行为的价格更高,而无安全套性行为的价格溢价从世界杯之前的36%分别升至世界杯期间的40%(p值<0.001)和世界杯之后的57%(p值<0.001)。在整个调查阶段,与阴道性行为相比,肛交、口交或手淫性行为更有可能在无安全套的情况下进行。性行为类型是所有阶段性行为价格的主要决定因素。我们展示了表明性证据,即2010年世界杯与性行为价格上涨和无安全套性行为供应增加有关。尽管这些发现应被解释为关联而非因果关系,但我们建议,主办重大活动且有大量性工作者人口的国家应明确考虑性工作的背景和结构,并推广以客户为中心的安全性行为干预措施,明确考虑性工作者为提供风险更高的行为所面临的经济压力,以尽量减少对健康的影响。
