Factors associated with condom use for oral sex among female brothel-based sex workers in Singapore.

ABSTRACT

PIP: Oral sex, which was once considered an uncommon sexual behavior, has become a relatively common practice. Its prevalence increased from 27.1% in 1992 to 81.1% in 1997, with a concomitant increase in pharyngeal gonorrhea among female sex workers in Singapore. The extent of condom use for oral sex among them is unknown. This cross-sectional study determined the prevalence of, and factors associated with, consistent condom use for oral sex among 225 female brothel-based sex workers, with paying clients in Singapore. Results indicated that slightly more than half (56.9%) consistently used condoms for oral sex compared to 97% for vaginal sex. Condom use was significantly associated with class of sex workers and negotiation skills. Significantly higher rates of condom use were found among high-class sex workers (adjusted rate ratio: 1.52; 95% CI: 1.01-2.29) and those with negotiation skills (adjusted rate ratio: 1.95; 95% CI: 1.32-2.07). In light of these findings, it is suggested that future interventions provide training to sex workers, particularly high-class ones, on negotiation concerning oral sex.
