Summary of the Document

Core Content

This document presents a systematic review and ecological analysis of the epidemiology of HIV and selected STIs (chlamydia, syphilis, gonorrhoea) among female sex workers (FSWs) in WHO-defined Europe. The study aims to understand the prevalence of HIV and STIs, the risk factors at both individual and structural levels, and the relationship between structural factors and national HIV prevalence estimates among FSWs.

Main Objectives

1. To assess the prevalence and incidence of HIV and STIs among FSWs.
2. To describe structural and individual-level risk factors associated with HIV and STI prevalence.
3. To examine the relationship between structural-level factors and national HIV prevalence among FSWs.

Key Findings

HIV Prevalence

• HIV remains low among FSWs who do not inject drugs in Western Europe (<1%).
• Syphilis and gonorrhoea are more prevalent than HIV in most regions.
• In Eastern Europe, HIV prevalence is higher, ranging from 2.5% to 8% in countries like Azerbaijan, Moldova, and Estonia.
• Injecting drug use is a major individual-level risk factor for HIV among FSWs.
• HIV prevalence is significantly linked to imprisonment in ecological analysis.
• In some Eastern European countries, HIV prevalence among FSWs is high despite relatively low levels of drug injecting, indicating other risk factors at play.

Structural and Individual-Level Risk Factors

• Structural factors include lack of access to services, working on the street, migration, and criminalisation of sex work.
• Individual-level factors include drug injecting, exposure to violence, and low condom use with non-paying partners.
• Violence is a common experience among FSWs, including physical and sexual violence from clients and police.
• Condom use is generally low, particularly with non-paying partners, increasing the risk of STIs.

Ecological Analysis

• Linear regression models were used to examine the relationship between HIV prevalence and structural-level indicators such as GINI coefficient, female-to-male pay differential, and number of people imprisoned per 100,000 population.
• The analysis suggests that HIV prevalence among FSWs is influenced by structural factors, such as injecting drug use and imprisonment rates.
• Microenvironmental and macroenvironmental factors interact to influence HIV/STI risk, highlighting the need for multilevel approaches in prevention strategies.

Key Messages

• HIV prevention among FSWs must be integrated with broader social welfare and structural interventions.
• Social determinants such as access to services, violence, and migration are critical in shaping HIV risk.
• Future studies should better delineate how micro and macro factors interact to influence HIV and STI risk.
• Structural-level factors have a significant impact on HIV prevalence among FSWs, especially in Eastern Europe.

Limitations

• Limited data on FSWs in some countries.
• Small sample sizes in certain studies.
• Inconsistent definitions and sampling methods across studies.
• Difficulty in comparing studies due to diverse confounders.
• Ecological analysis has limited capacity to capture complex relationships due to small number of country reports and descriptive linear associations.

Conclusion

The study underscores the importance of addressing structural determinants in HIV prevention among FSWs. It highlights the need for comprehensive policies that tackle social inequality, violence, and access to health services. The findings support the idea that HIV prevention among vulnerable populations requires multilevel strategies that go beyond individual-level interventions.
