Project for Reproductive Equity Through Volunteers and Entrepreneurship, Networks and Technology (PREVENT)

March 17, 2025 updated by: Dr. Karen Yeates

Project for Reproductive Equity Through Volunteers and Entrepreneurship, Networks and Technology: the PREVENT Project Protocol

The PREVENT Project is a multifaceted, adolescent friendly, culturally competent program aimed to address the issues surrounding unplanned pregnancies and lack of access and uptake of contraceptive services among adolescent girls. The intervention uses a mobile platform that provides educational SMS (Short Message Service) messaging, interactive voice response, and connects adolescent girls to community based AFSRH (Adolescent Friendly Sexual Reproductive Health) counselling services, as well as discreet contraceptive access points headed by female entrepreneurs. The program will be piloted for 12 months in various wards and villages in rural and urban Kilimanjaro, Tanzania.The acceptability and practicality of the intervention will be assessed using mixed methods. Questionnaires and focus groups will be conducted with the study participants, as well as the medical and non-medical volunteers at the start and end of the pilot. The study will be heavily supported by all-female non-medical social entrepreneurs and sexual reproductive health community mentors (volunteers), and, all-female medical reproductive health team. Recruitment will also take place in hair saloons (local hair braiding and styling establishments) and other female run business such as tailors and female clothing stores that have enlisted to become contraceptive access points in the study. There will be 2 intervention groups, control and case group. Both groups will receive educational SMS (text) messages on SRH (Sexual Reproductive Health) and access individually tailored educational resources through interactive voice response (IVR) services/system via PREVENT mobile platform. In addition to personal support to be able to contact with a SRH community peer mentor in the community for AFSRH counselling and support. The case group will then have access to contraception provided with detailed and discreet information on accessing PREVENT contraceptive access points in all communities included in the study.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Not yet recruiting

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 PREVENT study seeks to impact knowledge, perceptions, and behavioural changes regarding SRH among adolescent girls. As a result, the data collected in the PREVENT study will be grouped into two main themes: SRH knowledge and attitudes, as well as family planning (pregnancy avoidance) and contraceptive services uptake and outcomes. All data collected during the study will be directly entered and stored into the secure PREVENT mobile platform and related secure storage functions within the platform.

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

15 years to 19 years (Child, Adult)

Accepts Healthy Volunteers

Yes

  • Report being SMS literate (ie. able to read text messages in English or Swahili)
  • Be able and willing to return for follow-up after 12 months
  • Be able and willing to give written informed consent for enrollment in the study

Exclusion Criteria:

  • Be pregnant or planning pregnancy within 12 months (assessed when obtaining consent using HCG (human chorionic gonadotropin) urine dipstick).
