  ABSTRACT: Although sex work is highly stigmatized throughout the world, a limited body of research has examined stigma among female sex workers (FSWs). We developed a Sex Worker Stigma (SWS) Index to measure perceived stigma among 150 FSWs in Chennai, India. These women were at a median age of 35 years and reported, on average, having engaged in sex work for nine out of the previous 12 months. The two-factor structure of the index was verified in both exploratory and confirmatory factor analyses with acceptable goodness of fit. The final 10-item index comprises of two domains of perceived stigma from the community and perceived stigma from one's family. Cronbach's α coefficients were 0.87 and 0.88 for each domain, respectively. In regression analysis, we found that income from jobs other than sex work was correlated with decreased levels of perceived stigma from both the community (β = - 0.16; 95% CI: -0.30 and -0.02) and the family (β = - 0.24; 95% CI: -0.40 and -0.07); prior experience of accessing health care system increased perceived stigma from the community while heavier financial responsibility for the family was associated with lower perceived stigma from women's family. With the proposed SWS Index, we have a valid and reliable metric to document and track levels of perceived stigma among FSWs to assess the impact of stigma reduction interventions.

  ABSTRACT: Female sex workers have been central in India's HIV epidemic since it was first diagnosed among them in 1989. Female sex workers' risk of HIV is primarily economically motivated. The Pi pilot study examined the feasibility and association of a microenterprise intervention, the tailoring of canvas bags, on sexual risk behaviors among female sex workers (N = 100) in Chennai. Women were randomized to an intervention or control arm. Between-group comparisons at baseline and at six-month follow-up were performed. Multivariate linear regression with bootstrapping was conducted to estimate the intervention effect. At baseline, women were a median of 35 years old, 61% were married and they had an average of two children. Intervention participants reported a significantly lower number of sex partners and significant increases in income at the 6-month follow-up compared to control participants. In a multivariate model, intervention participants had a significantly lower number of paying clients per month at follow-up compared to control participants. By graduation, 75% of intervention arm participants had made at least one sellable canvas bag and 6 months after the study's end, 60% have continued involvement in bag production. The pilot study demonstrated that microenterprise interventions are successful in both providing FSWs with licit income opportunities and was associated with reductions in HIV risk behaviors.
