March 20, 2025 updated by: HIV Prevention Trials Network
Cash transfers to young women for staying in school and its effect on acquiring HIV

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The overall purpose of this study is to determine whether providing cash transfers to young women and their household, conditional on school attendance, reduces young women's risk of acquiring Human Immunodeficiency Virus (HIV). The overall goal of the Conditional Cash Transfer (CCT) intervention is to reduce structural barriers to education with the goal of increasing school attendance of young women, thereby decreasing their HIV risk.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

13 years to 20 years (Child, Adult)

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • Female aged 13 to 20 years.
  • Enrolled in grades 8, 9, 10 or 11 at the beginning of the study at schools in the AHDSS study site
  • Intending to continue to live in the study site until the end of the follow-up period.
  • Be willing and able to consent/assent to all study procedures including HIV and HSV-2 testing.
  • Able to read sufficiently to use ACASI.
  • Have a bank or post office account or have documentation to be able to open a bank or post office account (i.e., birth certificate, South African National Identification Book, or passport and proof of residence). Post Office accounts will only be required for participants in the Intervention arm.
  • Parent/Legal Guardian who lives with young woman, willing and able to consent to all study procedures including HIV and HSV-2 testing.
  • Parent/Legal Guardian has a bank or post office account or has documentation to be able to open a bank or post office account (i.e. South African National Identification Book, or passport and proof of residence). Note that the account may be opened in the name of any adult who resides in the household with the young woman.

Exclusion Criteria:

  • Pregnant by self-report at baseline.
  • Married at baseline.
  • No parent or legal guardian living in household.
  • Any other reason that the staff feels would jeopardize the health or well-being of the participant or staff or would prevent proper conduct of the study.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Other: A--Monthly cash transfers
Monthly cash transfer payments
Behavioral: monthly cash transfer payments for attending school
In the intervention, young women and their households will be randomized in 1:1 ratio to receive monthly cash transfer payments, conditional on the young woman attending school, or to the control arm. Young women will be recruited at the beginning of grades 8 through 11 in the first year of the study.
Other: B--No cash transfers
No cash transfers.
Behavioral: monthly cash transfer payments for attending school
In the intervention, young women and their households will be randomized in 1:1 ratio to receive monthly cash transfer payments, conditional on the young woman attending school, or to the control arm. Young women will be recruited at the beginning of grades 8 through 11 in the first year of the study.
Behavioral: B--No cash transfers
No monthly cash transfers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
HIV Incidence
Time Frame: 4 years
To determine whether young women who are randomized to receive CCTs conditional on school attendance have a lower incidence of HIV infection over time compared to young women who are not randomized to receive cash transfers.
4 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
HSV-2 incidence
Time Frame: 4 years
To determine whether young women who are randomized to receive CCTs conditional on school attendance have a lower incidence of Herpes Simplex Virus type 2 (HSV-2) infections over time compared to young women who are not randomized to receive cash transfers.
4 years
HSV Incidence
Time Frame: 4 years
To determine whether young women who receive the CCTs report less unprotected sex, fewer number of sexual partners, younger male partners, an older age of coital debut, a lower incidence of self-reported pregnancy, and greater school attendance compared to young women who do not receive the cash transfers.
