J Womens Health (Larchmt) 2011 20 (5) 733-8 BACKGROUND: We evaluated predictors of consistent condom use among female sex workers (FSWs), a core group for controlling the spread of HIV. METHODS: In an analysis of data collected in 2004-2005 from 140 Kenyan FSWs who completed questionnaires administered during a baseline study visit and three bimonthly follow-up visits, we used a case-crossover design to identify predictors of consistent condom use during all coital acts in the preceding 2 weeks, overall and by partner type. RESULTS: Participants (n=140) completed the baseline visit and 390 bimonthly follow-up visits. Alcohol use during sex was negatively associated with consistent condom use with helping partners (defined as regular sex partners to whom the woman could go for help or support if needed) (adjusted odds ratio [AOR], 2.6, 95% confidence interval [CI] 1.0-6.5) but not associated with condom use with other partners. Coital frequency was associated with condom use with other partners only. Women who reported 1-5 (AOR 11.0, 95% CI 4.3-28.3) or 6-9 recent coital acts (AOR 3.8, 95% CI 1.7-8.8) with other partners were more likely to report consistent condom use with those partners than were women who reported ≥10 acts. Having a recent partner delay payment was inversely associated with consistent condom use with helping, other, or all partners. CONCLUSIONS: Correlates of consistent condom use differed by partner type. By using a case-crossover design, we were able to identify potentially modifiable factors associated with consistent condom use by FSWs who used condoms consistently with a given partner type during some periods but not others. |
Intravaginal practices among female sex workers in Kibera, Kenya
Gallo MF , Sharma A , Bukusi EA , Njoroge B , Nguti R , Jamieson DJ , Bell AJ , Eschenbach DA . Sex Transm Infect 2010 86 (4) 318-22 OBJECTIVES: To assess vaginal cleansing and lubricant use among female sex workers (FSW) in Kenya participating in a 6-month, prospective study of the acceptability of the use of the diaphragm. METHODS: The study is based on 140 FSW in Nairobi, who completed 140 baseline visits and 390 bi-monthly follow-up visits. Participants were instructed to wear the diaphragm for all coital acts during follow-up and to refrain from vaginal cleansing while wearing the diaphragm. Logistic regression was used to identify predictors of recent vaginal cleansing to 'tighten' the vagina reported at baseline; recent vaginal cleansing to prevent infection reported at baseline; recent vaginal cleansing with the diaphragm in place reported during follow-up; and recent use of oil-based lubricant during coitus reported at baseline. RESULTS: At baseline, 99% of women reported vaginal cleansing in the previous 2 weeks for purposes of hygiene or to remove evidence of past coitus. Approximately 41% of women also reported cleansing in the past 2 weeks to 'tighten' the vagina. Women reported vaginal cleansing with the diaphragm in place in the past 2 weeks at 14% of follow-up visits in which the diaphragm was used. Predictors of such cleansing included young age, 6-month study visit, being divorced or widowed and higher educational level. CONCLUSIONS: While vaginal cleansing is a modifiable behaviour, given that cleansing for hygiene was almost universal among this study population at baseline and that more women reported cleansing while wearing the diaphragm as the study progressed, the complete eradication of the practice would probably be difficult. |
Diaphragm for STI and HIV prevention: is it a safe method for women at high risk?
Njoroge B , Gallo MF , Sharma A , Bukusi EA , Nguti R , Bell AJ , Jamieson DJ , Williams D , Eschenbach DA . Sex Transm Dis 2010 37 (6) 382-5 Female sex workers (n = 140) were enrolled in a 6-month acceptability trial of the diaphragm. We randomized a subset (n = 40) to receive colposcopies after 1 month of diaphragm use or after 1 month of observation before commencing diaphragm use. Adverse events were mild in nature. Frequency of colposcopic findings did not differ between women randomized to immediate versus delayed diaphragm use (P = 0.25). |
Promoting continuous use as a strategy for achieving adherence in a trial of the diaphragm with candidate microbicide
Penman-Aguilar A , Swezey T , Turner AN , Bell AJ , Ramiandrisoa FN , Legardy-Williams J , Randrianasolo B , Van Damme K , Dulyx J , Behets F , Jamieson DJ . AIDS Educ Prev 2009 21 (6) 512-25 Women need more choices for protection from HIV and other sexually transmitted infections (STIs). We conducted a randomized 4-week study in Madagascar in preparation for a Phase III randomized controlled trial (RCT) of the diaphragm with a candidate microbicide for STI prevention. All participants completed quantitative surveys; half participated in a qualitative interview. We advised women to wear the diaphragm at all times except for daily cleaning (rather than inserting it before intercourse). The objective of this analysis was to determine whether women who followed this "continuous use" approach more often used the diaphragm for 100% of sex acts as compared with other women. If so, this would support advising continuous diaphragm use in the upcoming RCT. To meet our objective, we analyzed qualitative data thematically, developed a measure of continuous diaphragm use based on qualitative data, and used multiple regression to evaluate the measure's association with adherence to diaphragm use during 100% of sex acts. Women who wore the diaphragm continuously had 4 times higher odds of reporting diaphragm use during 100% of sex acts (OR: 4.6, 95% CI: 1.2, 24.0). If the diaphragm proves effective against STI, continuous use may help women achieve high levels of protection. |
