Objectives
To better understand risk behaviours and factors associated with
low-fee female sex workers (FSW) and support HIV/sexually transmitted
infections (STI) epidemic control among this key population in China.
Methods
A cross-sectional study using convenience sampling to recruit 1487
eligible low-fee and medium-fee FSW was conducted in 2012 in three
provinces. The participants were interviewed using a structured
questionnaire and tested for HIV-1, herpes simplex virus (HSV)-2 and
syphilis antibody. Log-binomial modelling was used to estimate prevalence
ratios (PR) and examine factors associated with low-fee sex work.
Results
Prevalence of HIV-1, syphilis and HSV-2 antibody positive were
0.5%, 4.8% and 27.8%, respectively. Low-fee FSW were
more likely to have HSV-2 infection (adjusted prevalence ratio
(APR)=1.3, 95% CI 1.1 to 1.7), but not more likely to have
HIV-1 and syphilis infection compared with medium-fee FSW. Compared with
medium-fee FSW, low-fee FSW were more likely to be ≥35 years of age
(APR=2.1, 95% CI 1.3 to 3.6), engage in sex work ≥6
days/per week (APR=1.7, 95% CI 1.2 to 2.6), have ≥3
clients per day (APR=2.2, 95% CI 1.5 to 3.3), have clients
decide condom use (APR=1.6, 95% CI 1.1 to 2.3), fail to
persuade clients to use condoms (APR=1.6, 95% CI 1.1 to
2.6), express willingness to have unprotected sex in return for receipt of a
higher fee (APR=1.8, 95% CI 1.2 to 2.8), have had genital
symptoms in the past year (APR=1.4, 95% CI 1.1 to 1.8) and
have migrated from another city.
Conclusions
Low-fee FSW in China have unique risks for acquiring HIV/STI, in part
due to greater economic pressures. Tailored interventions targeting low-fee
FSW and incorporating their prevailing perception of HIV/STI risks and
condom use negotiation challenges that they face are urgently needed.
