Wang H, Chen RY, Sharp GB, Brown K, Smith K, Ding G, Jin X, Xu J, Dong R, Wang N - BMC Infect. Dis. (2010)

Bottom Line: This study describes FSW mobility patterns in a high risk area of China to identify factors associated with increased mobility, and to study the incidence and prevalence of HIV/STIs in this group. 270 FSWs recruited from a baseline cross-sectional study were invited to participate in a one-year monthly follow-up cohort study in Kaiyuan City, Yunnan Province, China from 2006 to 2007.The least mobile FSWs were from Kaiyuan, worked in higher risk venues, were more likely to use drugs and be HIV-infected.Because FSWs characteristics differ according to the venue at which they work, future prevention work should tailor programs according to venue with a particular focus on FSWs in higher risk venues.

ABSTRACT

Background: The mobility of female sex workers (FSWs) is a factor in the geographic spread of human immunodeficiency virus (HIV) and other sexually transmitted infections (STIs). This study describes FSW mobility patterns in a high risk area of China to identify factors associated with increased mobility, and to study the incidence and prevalence of HIV/STIs in this group.

Methods: 270 FSWs recruited from a baseline cross-sectional study were invited to participate in a one-year monthly follow-up cohort study in Kaiyuan City, Yunnan Province, China from 2006 to 2007. Laboratory tests were conducted for HIV/STIs at baseline, 6 and 12 months.

Results: A total of 117 (43.3%) FSWs moved to another city during the year. Risk factors for increased mobility included being from another city within Yunnan (adjusted hazard ratio [AHR] 1.67, 95% confidence interval [CI] 1.09-2.56), being from outside Yunnan (AHR 1.58, 95% CI 1.04-2.54), and working in lower risk entertainment establishments (AHR 1.55, 95% CI 1.03-2.35). HIV-positive subjects, drug users and FSWs in higher risk venue were less likely to change residence, less likely to use condoms with clients, and earned less per client, but had more working locations and more clients each month.

Conclusions: The least mobile FSWs were from Kaiyuan, worked in higher risk venues, were more likely to use drugs and be HIV-infected. Because FSWs characteristics differ according to the venue at which they work, future prevention work should tailor programs according to venue with a particular focus on FSWs in higher risk venues.

Overall follow-up rate by month and stratified by HIV sero-positivity and drug using for the 270 female sex workers included in the follow-up study. The follow-up rate of HIV-positive subjects was significant lower than that of HIV-negative subjects (P = 0.045), and the follow-up rate of illegal drug users was significant lower than that of non-drug users (P = 0.012).

Mentions: Figure 1 illustrates the follow-up retention rates for the entire cohort, stratified by subgroups. Overall, 159 (59%) of the 270 subjects enrolled completed the final follow-up visit. HIV-negative subjects (138 [62%]) were significantly more likely to be retained in the study than HIV-positive subjects (21 [45%], P = 0.04). FSWs who did not use drugs (132 [64%]) were also significantly more likely to be retained than drug users (27 [43%], P = 0.01). Twenty-two drug users, of whom 12 were HIV-positive, were arrested and sent to detoxification centers during the study.
