We read with interest the article by Mary Travis Bassett who reviewed
the barriers to voluntary counseling and testing (VCT). The author points
out that the main barriers to VCT are the lack of counselors, delays in
offering test results, lack of treatment availability and social factors
(1).
We conducted a case-control study to identify factors associated with
refusal for HIV VCT in sex workers (SWs) in Bobo-Dioulasso (Burkina Faso).
Between December 1997 and September 1998, 748 female SWs were included in
a cross sectional study, which aimed at analyzing their social and
anthropological characteristics. According to their practices
characteristics, SWs were classified into six different categories and
each group was organized with recognized leaders (2). Data regarding socio
-demographic characteristics, medical histories of STI, knowledge
regarding the transmission of HIV and prostitution practices were recorded
by the six leaders. Each SW included in the cross sectional study was
systematically offered an HIV screening test (free of charge), after a
face-to-face pre-counseling. A case, defined as a SW who accepted the VCT
(VCT+) was matched by age and leader to two controls SWs, who refused the
VCT (VCT-).
In the 748 SW included in the cross-sectional study, 135 women were
tested (18.0%). A total of 116 VCT+ and 232 VCT- were included in the case
-control study. There was no significant difference between the two groups
for the level of education, the duration of prostitution, at least a
history of treated STI in the past year, the level of knowledge regarding
the transmission of HIV, the number of clients and the report at least a
sexual act without using a condom during the last week. The fear of a non-
respect of the HIV test confidentiality result was the only variable
significantly associated with the refusal of VCT (odds ratio=2.08, 95%
confidence interval=1.10-4.07; p=0.02).
Despite the encouragement of the peers-counselors and the
infrastructure available, only 18.0% of the SWs were tested. Provision
factor such as confidentiality of health workers contributed to this low
acceptance rate (3, 4). The lack of confidentiality is one of the factors
responsible for the stigma, which are acknowledged as being major barriers
to HIV prevention and care (5). Our results suggest that urgent reflection
is required about the adaptation of VCT and health care services to
maximize their behavioral impact and to target confidential supportive VCT
for the SWs, a high risk group of population for HIV in sub-Saharan
Africa.
