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

A survey of condom use among female sex workers in Northern Sydney; declining condom use for fellatio

Condom use among female sex workers (FSWs) is dynamic. We conducted a survey, by anonymous questionnaire, of condom use among FSWs routinely attending our clinical service in Northern Sydney. Logistic regression models determined associations with inconsistent condom use. All 201 women approached completed a questionnaire. Chinese-born women comprised 67% of participants. The median age was 35 years. Clients requesting unprotected fellatio was reported by 95% of participants, and approximately two-thirds felt pressure to have unprotected fellatio and vaginal sex (VSI). Inconsistent condom use at work was reported by 74% for fellatio and by 24% for VSI. The strongest adjusted association with inconsistent condom use for fellatio was monetary inducement by clients (aOR = 40.7, 95% CI 4.87-340, p = 0.001). The only other significant adjusted association was age ≥ 30 years (p = 0.02). The strongest adjusted association with inconsistent condom use for VSI was also monetary inducement by clients (aOR = 56.1, 95% CI 9.26-340, p < 0.001). Other significant adjusted associations were Chinese-speaking participants (p = 0.03) and clients requesting unprotected VSI (p = 0.02). We report high levels of inconsistent condom use. Health promotion should assist FSWs, particularly those of Chinese ethnicity, develop skills in dealing with pressure for unprotected sex, particularly fellatio.

Sex Worker Health Outcomes in High-Income Countries of Varied Regulatory Environments: A Systematic Review

There is significant debate regarding the regulation of the sex industry, with a complex range of cultural, political and social factors influencing regulatory models which vary considerably between and within countries. This systematic review examined the available evidence on the relationship between different approaches to sex industry regulation in high-income countries, and associated effects on sex worker health status. Objectives included identification of sex worker health outcomes, including sexual health, substance use and experience of stigma and violence. A search was performed electronically in eight scholarly databases which yielded 95 articles which met the criteria for inclusion. Findings suggested that sex workers in legalised and decriminalized countries demonstrated greater health outcomes, including awareness of health conditions and risk factors.

The prevalence and correlates of oral sex among low-tier female sex workers in Zhejiang province, China

Objectives

Oral sex and its associated factors among low-tier female sex workers (FSWs) have not been documented in the Chinese literature. Here, we report this perspective in this group.

Methods

The data were derived from a large cross-sectional study conducted among low-tier FSWs using a structured questionnaire in 21 counties in Zhejiang province, China. The prevalence of oral sex and its associated factors among 2645 low-tier FSWs were analyzed using bivariate and multivariate analysis.

Results

Of all participants, 579 (21.9%) had performed oral sex with clients over the previous month. Multivariate analysis revealed that oral sex is related to being unmarried, low income, early initiation of commercial sex, having conducted commercial sex in more counties, longer duration of commercial sex, larger number of clients, ever having engaged in anal sex, less use of condoms and oral contraceptives during the previous month, low rate of adoption for contraception at the present time, and STI-related symptoms during the previous half year.

Conclusion

Oral sex practitioners among low-tier FSWs in China are at a higher risk of STI, HIV, and unwanted pregnancy compared to those who did not engage in oral sex. Behavioral interventions carried out among low-tier FSWs should specifically target low-tier FSWs who practice oral sex, should carefully take into account the characteristics of these FSWs, provide risk awareness education and training for condom use negotiation, and promote the availability of condom and reproductive health care, timely diagnosis, and treatment of STIs.

Oral sex practices, oral human papillomavirus and correlations between oral and cervical human papillomavirus prevalence among female sex workers in Lima, Peru

Few data exist on oral human papillomavirus (HPV) prevalence in female sex workers (FSWs). Information regarding oral sex practices of 185 Peruvian FSWs, 18-26 years of age, was obtained via survey and compared with HPV testing results of oral rinse samples. Oral HPV prevalence was 14/185 (7.6%); four (28.9%) HPV genotypes were carcinogenic. One hundred and eighty-two participants reported having had oral sex; 95% reported condom use during oral sex with clients and 9.5% with partners. Women who had oral sex more than three times with their partners in the past month were more likely to have oral HPV than women who had oral sex three times or less (P = 0.06). Ten (71.4%) women with oral HPV were HPV-positive at the cervix; conversely 8.3% of women with cervical HPV were HPV-positive in the oral cavity. The prevalence of oral HPV was relatively low, considering the high rates of oral sex practiced by these women.

Women's reports of condom use in Thai couples under intensive and regular STI/HIV risk reduction counseling

The objective of this study was to determine factors affecting condom use and condom use rates among Thai couples. A cohort of 1,391 reproductive aged women who attended seven family planning clinics in all regions of Thailand and met study eligibility were followed at 3-month intervals for 15-24 months. At each visit, the woman was interviewed about sexual risk behaviors and counseled for sexual risk reduction and condom use. Condoms were provided free of charge. The women were classified into 3 groups according to contraceptive use at baseline: single contraceptive method group, dual methods consisting of contraceptives with condoms, and condoms only. We found that condom use rates were generally low in all contraceptive groups. Significant factors affecting condom use in multivariate analyses included, contraceptive method at baseline, polygynous marriage, higher education, engaging in commercial sex work, multiple sex partners, sex during menses, more frequent sex, laboratory confirmed STIs, husbands spending nights away from home, husbands having sex with other women, and penile ulcers or sores.

Long-term effects of condom promotion programmes for vaginal and oral sex on sexually transmitted infections among sex workers in Singapore

OBJECTIVES

To evaluate the long-term impact of condom promotion programmes for vaginal and oral sex among female brothel-based sex workers in Singapore.

DESIGN

A pre-test/post-test comparison group followed by a time series design was used to compare trends in condom use for vaginal sex and cervical gonorrhoea incidence from 1990 to 2002 across cross-sectional samples of sex workers before and after programme implementation in 1995. The subsequent condom promotion programme for oral sex was evaluated using the interrupted time series with a retrospective pre-test to post-test matched control group design.

METHODS

Sex workers completed a questionnaire before and 6 months after participation in educational sessions. Cervical and pharyngeal swabs were taken monthly for cultures for Neisseria gonorrhoeae.

RESULTS

Consistent condom use for vaginal sex increased significantly from < 45.0% before 1995 (pre-intervention period) to 95.1% in 2002, with a corresponding decline in cervical gonorrhoea incidence from > 30 to 2/1000 person-months. Adjustment for temporal changes in sociodemographic characteristics did not materially alter the trends. Consistent oral condom use increased significantly from < 50% before 1996 to 97.2% in 2002, with a corresponding decline in pharyngeal gonorrhoea from > 12 to 4.7/1000 person-months.

CONCLUSION

The interventions produced sustained high levels of condom use for vaginal and oral sex with corresponding declines in cervical and pharyngeal gonorrhoea incidence.

Promoting condoms for oral sex: impact on pharyngeal gonorrhea among female brothel-based sex workers

BACKGROUND

Low condom use for oral sex among female brothel-based sex workers in Singapore has led to a rise in pharyngeal gonorrhea.

GOAL

The goal of the study was to evaluate a program promoting the use of condoms for oral sex.

STUDY DESIGN

We used the time-series design to compare condom use and pharyngeal gonorrhea trends before and after program intervention in 1996 and the pretest-posttest matched control group design to determine the impact of brothel interventions on sex workers.

RESULTS

Consistent oral condom use increased significantly from 42.2% in 1996 to 89.9% in 2000, with a corresponding decline in pharyngeal gonorrhea (in comparison with no significant changes before intervention). Among sex workers in brothels with interventions there was a 10.8% absolute increase in condom use, compared with an 11.7% decrease in condom use in the control group. The gonorrhea incidence rate was also significantly much lower in the intervention group than in the control group (adjusted risk ratio: 0.22; 95% CI: 0.06-0.78).

CONCLUSION

The intervention increased oral condom use, with a decline in the incidence of pharyngeal gonorrhea.

Designing an Oral Sex Condom Promotion Program for Female Sex Workers in Singapore

In 1996, a health promotion program began to increase condom use for oral sex among female brothel-based sex workers in Singapore. It was initiated based upon increasing evidence of HIV transmission through oral sex as well as increased oral sex among these workers and their clients. Condom use for oral sex increased from 42.2 percent in 1996 prior to the program to 91.7 percent in mid-2000, with a corresponding decline in pharyngeal gonorrhea from its peak of 10.7 percent to 3.6 percent (compared to no significant changes in the two-year period before intervention). A significant increase in oral condom use with decreased pharyngeal gonorrhea incidence was observed among sex workers where brothel educational interventions took place compared with matched controls without brothel interventions. This case study describes the application of a health promotion framework to effect behavior change. Major differences in the behavioral risk-education strategies and message contents between this program and our earlier program on condom use for vaginal sex also are highlighted.
