The Effect of HIV Self-Testing Delivery Models on Female Sex Workers' Sexual Behaviors: A Randomized Controlled Trial in Urban Uganda.

ABSTRACT: HIV self-testing increases recent and frequent HIV testing among female sex workers (FSWs) in urban Uganda. Using results from a randomized controlled trial, we aim to establish the effect of HIV self-testing delivery models on FSWs' sexual behaviors in this setting. Clusters of one peer educator and eight participants were 1:1:1 randomized to: (1) direct provision of an HIV self-test, (2) provision of a coupon for facility collection of an HIV self-test, or (3) referral to standard-of-care HIV testing services. Sexual behaviors were self-reported at 1 and 4 months. From October to November 2016, 960 participants were enrolled and randomized. At 4 months, there were no statistically significant differences in participants' sexual behaviors, including inconsistent condom use, across study arms. We do not find any changes in sexual risk-taking among FSWs in response to the delivery of HIV self-tests. Routine policies for HIV self-testing are likely a behaviorally safe component of comprehensive HIV prevention strategies.

Project description:BackgroundGlobally, female sex workers (FSW) are disproportionately affected by HIV and other sexually transmitted infections (STIs). However, uptake of STI and HIV testing services among FSW in sub-Saharan Africa remains low. We aimed to assess the effect of FSW-led peer education and text message reminders on 3-monthly syphilis and HIV testing among FSW in Uganda.MethodsBetween September 2019 and February 2020, we implemented weekly peer education sessions and bi-monthly SMS reminders for FSW in Mbarara (intervention city). Peer education sessions were implemented by 20 FSW, who received five days of basic training as peer educators. We held monthly meetings with peer educators throughout the six-month implementation period. FSW in Mbale (control city) continued to receive standard of care consisting of HIV testing outreach campaigns, and facility-based testing. Using a quasi-experimental design in one intervention city, and one control city, we conducted pre- and post- questionnaire-based surveys on recent syphilis and HIV testing behavior among FSW in July-October 2018, and March 2020. We compared proportions and prevalence ratios at baseline and follow-up using chi-square tests and negative binomial regression.ResultsWe conducted 436 interviews (200 before/236 after) with FSW. At baseline similar proportions reported taking an HIV test (57 % vs. 54 %; p = 0.72), and a syphilis serology test (35 % vs. 39 %; p = 0.67) in the intervention and control cities, respectively, in the prior three months. After the intervention, this proportion increased to 82 % (95 % confidence interval [CI] 74.0-88.2) for HIV, and 81 % (95 % CI: 73.0-87.0) for syphilis in the intervention city. Relative to baseline in the control city, the proportion testing for HIV was unchanged (52 %) but decreased for syphilis (26 %).ConclusionsBi-monthly text message reminders with weekly peer education sessions increased uptake of 3-monthly syphilis and HIV testing in a Ugandan female sex work population and could help increase sex worker engagement in HIV/STI services in line with World Health Organization recommendations.

Project description:Highly Exposed-Seronegatives (HESN) individuals do not contract HIV-1 infection despite long-term exposure; few comprehensive studies examining behavior, mucosal tissue, and peripheral immune parameters in sexually-exposed HESN have been completed. To this end, we assessed rate of condomless vaginal sex, the immune activation status (peripheral blood) and gene expression (ectocervical biopsies) in female cohort of high-risk female sex workers [FSW] (n=50) and non-sex worker women [CG] (n=32) in San Juan, Puerto Rico, USA. Of the 50 FSWs examined only 5 had detectable anti-HIV responses by either HIV gag-specific CD8+ T-Cell responses or mucosal anti-HIV envelope IgG/IgA. FSW had a uniform lower CD38 expression on circulating CD4+ or CD8+ T-Cells (both: p<0.0001:Wilcoxon Rank Sum). Cervical tissue from FSWs had greater levels of CD4+ T-Cell (p=0.040), CD123+ plasmacytoid Dendritic Cells (p=0.013) and CD68+ macrophage infiltrates (p=0.038). Cervical gene expression by RNA microarray indicated that FSW had a gene signature characterized by lower expression of genes associated with leukocyte homing and chemotaxis; partial interferon regulated gene signature; and lower gene expression of genes required for HIV infection such as CD4 and NUP153 indicating a lower mucosal immune activation state and reduced susceptibility to HIV-1 infection within mucosal tissue. Notably, Interferon (IFN)-ε expression was higher in FSW than CG women, as detected by RNA (microarray) and protein (IHC) expression in cervical epithelium. The observed levels of IFNε were associated with the reported frequency of unprotected intercourse. Finally, IFNε was induced by treatment of the ECT1 cell line with seminal fluid, suggesting that semen exposure may contribute to long-term protection. Decreased levels of immune activation and gene expression required for HIV infection along with semen-induced epithelial Interferon ε production within the reproductive tract of FSWs highlight distinct host intrinsic resistance mechanisms that may contribute to long-term HIV seronegative status in spite of high-risk condomless sex.

Project description:Lifestyle behaviors significantly impact health, yet remain poorly defined in Chinese rural-to-urban migrants.In a cross-sectional study of health-related behaviors of 5484 rural-to-urban migrants who had worked in Shanghai for at least six months, we assessed the contribution of demographics and physical and mental health to lifestyle behaviors in male and female participants by multiple stepwise cumulative odds logistic regression.Respondents were 51.3% male. 9.9% exhibited abnormal blood pressure; 27.0% were overweight or obese; 11.2% reported abnormal mental health; 36.9% reported healthy lifestyle. Multiple stepwise cumulative odds logistic regression indicated that men working in manufacturing reported less unhealthy lifestyle than those in hospitality (cumulative odds ratio (COR) = 1.806, 95%CI 1.275-2.559) or recreation/leisure (COR = 3.248, 95%CI 2.379-4.435); and women working in manufacturing and construction reported less unhealthy lifestyle than those in all other sectors. Unhealthy lifestyle was associated with small workplaces for men (COR = 1.422, 95%CI 1.154-1.752), working more than 8 or 11 hours per day for women and men, respectively, and earning over 3500 RMB in women (COR = 1.618, 95%CI 1.137-2.303). Single women and women who had previously resided in three or more cities were more likely to report unhealthy lifestyle (COR = 2.023, 95%CI 1.664-2.461, and COR = 1.311, 95%CI 1.072-1.602, respectively). Abnormal mental status was also correlated with unhealthy lifestyle in men (COR = 3.105, 95%CI 2.454-3.930) and women (COR = 2.566, 95%CI 2.024-3.252).There were different risk factors of unhealthy lifestyle score in male and female rural-to-urban migrants, especially in number of cities experienced, salary, marital status, work place scale. Several demographic groups: employment sectors (e.g. hospitality and recreation/leisure), working conditions (e.g. long hours) and abnormal mental status were associated with unhealthy lifestyle behaviors in Chinese rural-to-urban migrants, and health interventions should be targeted to these groups.
