“…The comparatively higher levels of risk behaviours and HIV prevalence observed among SSWs are in line with previous studies and reinforce the idea that prevention interventions should take into consideration the structure of commercial sex work with regard to different subpopulations of FSWs. [9][10][11][12][13][14][15][16][17][18] Among various risk behaviours, injecting drug use was found in this study to be most strongly associated with HIV infection among FSWs, regardless of sex work venue, as has been reported previously in multiple settings. 15,17,[24][25][26][27][28][29][30] The finding is worrisome and highlights the importance of strategies to address this behaviour in HIV prevention activities targeting FSWs.…”

Commercial sex work is one of the driving forces of the HIV epidemic across the world. In Vietnam, although female sex workers (FSWs) carry a disproportionate burden of HIV, little is known about the risk profile and associated factors for HIV infection among this population. There is a need for large-scale research to obtain reliable and representative estimates of the measures of association. This study involved secondary data analysis of the 'HIV/STI Integrated Biological and Behavioral Surveillance' study in Vietnam in 2009-2010 to examine the correlates of HIV among FSWs. Data collected from 5298 FSWs, including 2530 street-based sex workers and 2768 venue-based sex workers from 10 provinces in Vietnam, were analyzed using descriptive statistics and bivariate and multivariate logistic regression analyses. HIV prevalence among the overall FSW population was 8.6% (n = 453). However, when stratified by FSW subpopulations, HIV prevalence was 10.6% (n = 267) for street-based sex workers and 6.7% (n = 186) for venue-based sex workers. Factors independently associated with HIV infection in the multivariate analysis, regardless of sex work types, were injecting drug use, high self-perceived HIV risk, and age ≥ 25 years. Additional factors independently associated with HIV risk within each FSW subpopulation included having ever been married among street-based sex workers and inconsistent condom use with clients and having sex partners who injected drugs among venue-based sex workers. Apart from strategies addressing modifiable risk behaviours among all FSWs, targeted strategies to address specific risk behaviours within each FSW subpopulation should be adopted.

“…Although the proportion of IDUs with higher education was even lower, selective sampling (low homophily) within this IDU subset may be explained by the substantially larger size of the target population in the region (estimated 2,000 FSWs and 10,000 IDUs in Tallinn area). 11,12 These studies were limited in that the full network-size question was not asked (the definition of the population, age range, and geographical regions were missing). The network size-question sets up the probability of inclusion into the sample, and omission of eligibility criterion results in the possible overestimation of participants' network sizes.…”

“…FSWs, mostly concentrated in the capital, Tallinn, have an estimated HIV prevalence of 7.6% 11 and tend to work in a hierarchy of locations ranging from elite brothels and "love flats" to truck stops. Cellular phone and internet technology enables sex work to be highly dispersed and spatially mobile.…”

Evaluating Recruitment among Female Sex Workers and Injecting Drug Users at Risk for HIV Using Respondent-driven Sampling in Estonia

et al. 2010

Few recent publications have highlighted theoretical and methodological challenges using respondent-driven sampling (RDS). To explore why recruitment with RDS may work in some populations and not in others, we assess the implementation of RDS to recruit female sex workers (FSWs) and injection drug users (IDUs) into a human immunodeficiency virus biological and risk behavior survey in Tallinn, Estonia. Recruitment of FSWs was slower and more challenging than that of IDUs. The IDU study recruited 350 participants within 7 weeks, while the FSW study recruited 227 participants over 28 weeks. Implementation modifications that did not negatively impact key RDS theoretical and methodological requirements were used to improve recruitment during the FSW study. We recommend that all RDS studies include a formative research process to involve the participation of target populations and key persons associated with these populations in the study planning and throughout the implementation processes to improve recruitment from the outset and to respond to poor recruitment during data collection.

“…Three studies that utilized probabilistic sampling methods, by using RDS, were the result of this process. [28][29][30] In Vietnam, this method showed to be effi cient to recruit different types of SW. 28 It is worth mentioning, however, that probabilistic sampling methods also present important limitations. In cases of conglomerate sampling, it is diffi cult to have a complete list of all prostitution locations and the selection probabilities are, in general, unknown, and approximations are considered at the data analysis.…”

Introduction:We investigated sampling methods being used to estimate the HIV prevalence rate among female commercial sex workers. Methods: The studies were classifi ed according to the adequacy or not of the sample size to estimate HIV prevalence rate and according to the sampling method (probabilistic or convenience). Results: We identifi ed 75 studies that estimated the HIV prevalence rate among female sex workers. Most of the studies employed convenience samples. The sample size was not adequate to estimate HIV prevalence rate in 35 studies. Discussion: The use of convenience sample limits statistical inference for the whole group. It was observed that there was an increase in the number of published studies since 2005, as well as in the number of studies that used probabilistic samples. This represents a large advance in the monitoring of risk behavior practices and HIV prevalence rate in this group.

Abstract: Prevention needs of FSW in this area include increasing rates of HIV testing and putting in place effective programmes that can help extend HIV prevention behaviours across a range of sexual and drug use risk behaviours.
