Survey on STI among female sex
workers in 5 border provinces of Vietnam
BACKGROUND: Little is known about the true magnitude of STIs
sex workers (FSWs) in Vietnam. This study was conducted to
prevalence of selected STIs including HIV among FSWs in five
provinces of Vietnam.
METHODS: A total of 911 FSWs in 5 border provinces of Vietnam
Quangtri, Dongthap, Angiang and Kiengiang) participated in a
sectional study between December 2002 and January 2003. The
were interviewed about selected socio-demographic and
characteristics, history of STIs and selected features
spouses (husbands or live-in partners) or lovers by a standard
schedule. Serum was tested for HIV (1SFD+2ELISA) and syphilis
and urine tested for gonorrhea and chlamydia using the Roche
technique. Univariate and multivariate logistic regression
used to explore the association between STI/HIV and other
FSWs and their spouses or lovers.
RESRULT: Overall, the prevalences of HIV, syphilis, gonorrhoea,
and gonorrhoea and or chlamydia among FSWs in the 5 border
Vietnam were 4.5%, 10.7%, 10.7%, 11.9% and 19.9%,
respective prevalences of HIV, syphilis and either gonorrhoea
in the five provinces was as follows: LaiChau 2.0%, 1.0%,
1.0%, 12.9%, 32.7%; Dongthap 4.7%, 11.4%, 16.0%; Angiang 7.0%,
11.3% and Kiengiang 4.0%, 13.4%, 24.4%. The prevalence of HIV
in the southern border region (>4.0%) while that of NG/CT
predominant in the northern and central regions (>27%). The
syphilis was low in Laichau but higher than 10% in the other
provinces. Factors associated with NG/CT included, income
500,000VND/month, spouse's age <30 and spouse's complaint
of burning or
pain during sex with OR of 2.98, 3.78 and 10.62, respectively.
associated with HIV included age at first sex 15 (OR=11.13),
(OR=5.27) and spouse's age < 30 (OR=7.55).
CONCLUSIONS: STIs and HIV among FSWs are important public
in the border provinces of Vietnam although epidemic patterns
different between northern, central and southern regions.
treatment for cervicitis among FSWs should be applied to areas
prevalence of NG/CT is greater than 20%. Interventions
involving IEC, VCT,
100% condom use programme and management of STIs should be
strengthened and expanded.
