This cluster randomized trial will assess whether the provision of multiple oral-fluid based HIV self-test kits to HIV-negative women at high risk of acquiring HIV in western Kenya is an approach that promotes HIV testing among women's sexual partners, facilitates better sexual decision making, and reduces women's risk of acquiring HIV.
The study will recruit HIV-negative adult women who had two or more sexual partners within the past four weeks in the Nyanza region of Kenya. Beach communities and female sex worker hotspots will be randomized to an intervention group or a control group. In intervention clusters, participants will receive multiple oral fluid-based HIV test kits over a period of up to 24 months, training on how to use the tests, and encouragement to offer tests to current and potential sexual partners with whom sex without condoms is likely. In the comparison clusters, participants will be given referral vouchers for clinic-based HIV testing over a period of up to 24-months and encouraged to distribute these vouchers to sexual partners. Data will be collected from study participants at baseline on demographic and socio-economic characteristics, self-reported sexual behavior, HIV testing history, intimate partner violence history, and mental health outcomes. Follow-up data collection will occur every 6 months. Each month, participants will be sent an invitation to participate in short mobile phone based text message surveys. HIV testing of participants will occur at baseline and at 6 monthly intervals. Based on their reported use of the HIV self-tests, participants will be invited for qualitative interviews to learn more about their interactions with partners with regard to the distribution of self-tests and referral vouchers. Participants will also be given information to distribute to some of their male partners so that those partners can contact study staff to participate in qualitative interviews that will inquired about their perceptions of self-tests. The study has 3 specific aims. Aim 1 will determine the intervention's effect on uptake of HIV testing and identification of HIV infection among participants' sexual partners, self-reported sexual behavior of participants with partners whose HIV status was HIV-positive or not known, and HIV incidence among participants. Aim 2 will use a mixed methods approach to assessing safety and perceptions of the intervention by participants and their sexual partners. Aim 3 will assess the cost-effectiveness of the intervention and obtain information necessary to inform scale-up of the intervention in Kenya and other countries.

Participants will be given multiple Oraquick Advance HIV-1/2 test kits for testing themselves more frequently and for offering to selected sexual partners.

The intervention is designed to facilitate partner and couples testing, with resulting reduction in risky sexual behavior and HIV incidence among participants.

HIV Incidence Per 100 Person Years
HIV incidence over an average follow-up period of 18 months, and up to 24 months, per 100 person years
Time frame: up to 24 months
Identification of HIV-positive Male Partners
Average number of sexual partners per participant that the participant reported as HIV positive over the course of the study (Total reported positive sexual partners divided by number of participants who completed at least one 6-month follow-up survey); the intent of this measure is to see if participants given HIV self-tests are more likely to identify HIV positive sexual partners.
Time frame: up to 24 months
Used Condom With at Least One Partner After Partner Refused Self-test or HIV Testing Services Referral Card, or Tested HIV-positive
Percentage of participants who used a condom with at least one sexual partner after partner refused self-test or HIV testing services referral card, or tested HIV-positive; Note that percentages are rounded to one decimal place.
Time frame: Data was measured longitudinally up to 24 months for some subjects; all participants were measured through 18 months. Measures reported are from 18 month follow-up for behavior occurring in the past 6 months.
Couples Testing With Primary Partner
Percentage of participants who report testing together with their primary partner; Note that percentages are rounded to one decimal place.
Time frame: Data was measured longitudinally up to 24 months for some subjects; all participants were measured through 18 months. Measures reported are from 18 month follow-up for behavior occurring in the past 6 months.
Primary Partner Tested for HIV
Percentage of participants who report that their primary partner tested for HIV since enrollment; Note that percentages are rounded to one decimal place.
