Risk of HIV infection among indoor and street sex workers and their use of health services in Belgrade, Serbia

Factors mediating HIV risk among female sex workers in Europe: a systematic review and ecological analysis

OBJECTIVES

We reviewed the epidemiology of HIV and selected sexually transmitted infections (STIs) among female sex workers (FSWs) in WHO-defined Europe. There were three objectives: (1) to assess the prevalence of HIV and STIs (chlamydia, syphilis and gonorrhoea); (2) to describe structural and individual-level risk factors associated with prevalence and (3) to examine the relationship between structural-level factors and national estimates of HIV prevalence among FSWs.

DESIGN

A systematic search of published and unpublished literature measuring HIV/STIs and risk factors among FSWs, identified through electronic databases published since 2005. 'Best' estimates of HIV prevalence were calculated from the systematic review to provide national level estimates of HIV. Associations between HIV prevalence and selected structural-level indicators were assessed using linear regression models.

STUDIES REVIEWED

Of the 1993 papers identified in the search, 73 peer-reviewed and grey literature documents were identified as meeting our criteria of which 63 papers provided unique estimates of HIV and STI prevalence and nine reported multivariate risk factors for HIV/STI among FSWs.

RESULTS

HIV in Europe remains low among FSWs who do not inject drugs (<1%), but STIs are high, particularly syphilis in the East and gonorrhoea. FSWs experience high levels of violence and structural risk factors associated with HIV, including lack of access to services and working on the street. Linear regression models showed HIV among FSWs to link with injecting drug use and imprisonment.

CONCLUSIONS

Findings show that HIV prevention interventions should be nested inside strategies that address the social welfare of sex workers, highlighting in turn the need to target the social determinants of health and inequality, including regarding access to services, experience of violence and migration. Future epidemiological and intervention studies of HIV among vulnerable populations need to better systematically delineate how microenvironmental and macroenvironmental factors combine to increase or reduce HIV/STI risk.

Review of HIV vulnerability and condom use in central and eastern Europe

The epidemiological trend of increasing HIV incidence rates due to sexual transmission in central and eastern Europe has been documented. The current review analysed research articles that report on a wide spectrum of vulnerable populations from this world region. Studies of injection drug users, commercial sex workers, men who have sex with men, adolescents and young adults all reported inconsistent condom use. However, these patterns varied across populations and geographic areas. Populations in former Soviet countries - the most affected by HIV - also often appeared to have lower condom use rates. Intensified, comprehensive and locally tailored measures to curb sexual HIV transmission are urgently needed. Social development programs need to incorporate HIV prevention.
