A Savings Intervention to Reduce Men's Engagement in HIV Risk Behaviors
Study Details
Study Description
Brief Summary
This randomized control trial will test an economic intervention to reduce Kenyan men's engagement in behaviors that increase the risk of HIV/STIs. Participants randomized to the intervention group will be able to open accounts with a partner bank and will be incentivized to save with lottery-based rewards.

Detailed Description
This project will evaluate an innovative, theoretically-motivated economic intervention to reduce men's engagement in transactional sex and other risky behaviors. Leveraging innovations in mobile financial services and research on savings behavior in low-income countries, the investigators propose to test an intervention that seeks to motivate high-risk, income-earning men in western Kenya to reduce their spending on risky behaviors and instead save their disposable income in local bank accounts. These bank accounts will include additional incentives to save in the form of lottery-based rewards linked to amounts saved. The intervention will also encourage participants to develop savings goals and strategies, and provide periodic reminders about saving regularly. Through a direct economic mechanism (incentives to shift expenditures from the present to the future) and a psychological mechanism (increasing future orientation), the investigators hypothesize that the intervention will result in increased savings, reduced spending on transactional sex and alcohol, less risky sexual behavior, and reduced risk of HIV and sexually transmitted infections (STIs).
The investigators will conduct a randomized controlled trial among men who are at high risk of HIV and STI infection and determine the effects of a savings intervention on health and economic outcomes. Specific aims of the project are as follows. Aim 1: Determine the impact of the intervention on savings and investment behavior, self-reported sexual behavior, and incidence of HIV/STIs. Aim 2: Quantitatively and qualitatively assess mechanisms of behavior change among participants and a sample of their female partners.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: Mobile banking account with incentives to save Participants in the savings intervention group will be provided with basic information on the importance of saving for the future, as well as (a) lottery-based incentives to save, (b) opportunities to develop savings goals, and (c) periodic reminders about the savings incentives and goals. Participants will receive assistance in opening and using a mobile savings account and will receive an education session that emphasizes the importance of saving for the future. Participants will be told about lottery-based incentives for saving money in their account. |
Behavioral: Receives mobile banking account with incentives to save
Participants will receive assistance in opening and using a mobile savings account, will be given education emphasizing saving practices and will be told about lottery-based incentives opportunities.
|
No Intervention: Basic health and financial education Participants in the control group will be given basic information on the importance of saving for the future. In addition, health education curriculum developed by Impact Research & Development Organization (IRDO) will be provided to participants with standard health education on places to seek services for HIV and STI prevention and treatment, including information on alcohol and transactional sex as risk factors for HIV transmission. |
Outcome Measures
Primary Outcome Measures
- Incidence of HIV and other STIs [24 months]
Composite incidence of at least one of HIV or other STIs (herpes simplex virus type 2 (HSV-2), Neisseria gonorrhoeae (NG), and Chlamydia trachomatis (CT)) over 24 months. The investigators will combine all STIs (including HIV) into a composite variable, with each participant counting once. For participants who are HIV-positive at baseline or HSV-2-positive, the outcome will be defined over all STIs other than HIV.
Secondary Outcome Measures
- Expenditures on alcohol [6 month intervals]
Money spent on alcohol.
- Expenditures on transactional sex [6 month intervals]
Money, goods, and services spent on transactional sex (defined broadly to include financial and non-financial transfers to commercial and non-commercial sexual partners).
- Expenditures on gambling [6 month intervals]
Money spent on gambling.
- Number of sexual partners [6 month intervals]
Number of sexual partners participant had in the past 3 months.
- Recent engagement in transactional sex [6 month intervals]
Whether participant engaged in transactional sex (defined broadly to include financial and non-financial transfers to commercial and non-commercial sexual partners), or not in the past 3 months.
- Number of transactional sex partners [6 month intervals]
Total number of transactional sex partners participant had in the past 3 months.
- Number of transactional sex encounters [6 month intervals]
Number of transactional sex encounters participant engaged in during the past 3 months.
- Condom use at most recent sexual encounter [6 month intervals]
Whether participant used a condom or not at most recent sexual encounter in the past 3 months.
- Alcohol use [6 month intervals]
As measured by the Alcohol Use Disorders Identification Test-Concise (AUDIT-C) scale. The AUDIT-C is scored on a scale of 0-12, and higher values mean worse outcomes
- HIV, CT, and NG incidence between 0-12 months and 12-24 months [Up to 24 months]
More temporally granular measures of incidence for HIV, CT, and NG.
- Engagement in care among those who are HIV-positive [6 month intervals]
Whether or not participants who are HIV-positive are currently engaged in care for their HIV.
- Expenditures on food [6 month intervals]
Money spent on food items.
- Expenditures on household needs [6 month intervals]
Money spent on household needs (e.g., utilities).
- Savings and investment [6 month intervals]
Total savings and investment, defined as the money value of formal and informal savings as well as investments in physical and human capital.
- Total formal savings [6 month intervals]
The sum of savings balances in all formal bank accounts.
- Total household assets [6 month intervals]
Value of all assets.
- Expenditure on human capital investment [6 month intervals]
Money spent on human capital investment (e.g., spending on children's education).
- Expenditure on productive assets [6 month intervals]
Money spent on productive assets (e.g., spending on agricultural equipment).
- Expenditure on housing improvement [6 month intervals]
Money spent on structure of dwelling.
