Can a 5-Hour class cut teen pregnancies in rural areas?
NCT ID NCT06574321
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a program called Wrap It Up (WIU) for 11th and 12th graders in rural California. The program is a short booster course (4-5 hours) that builds on earlier sex ed to help teens make informed decisions about sex, contraception, and STDs. Researchers will compare students who get WIU to those who don't, tracking whether they avoid unprotected sex over 6 and 12 months. The goal is to see if this low-cost approach can lower high unintended pregnancy rates in rural communities.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Wrap It Up (WIU) sexual health education booster program
- What this could lead to
- If effective, this program could reduce unintended pregnancies and STDs among rural teens, providing a scalable school-based prevention tool.
- What could go wrong
- This is a first rigorous trial; earlier evidence was preliminary. Results rely on self-reported behavior, which may be biased, and the program's impact may vary across schools.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Since the study is a cluster RCT, we will identify partner schools before determining eligibility at the individual student level. Each school will participate for 2 years and be randomly assigned to an "intervention first" or "control first" arm. Schools will select a class or other group comprising mostly or solely 11th and 12th graders (e.g., a science class, the 11th grade annual retreat) for us to carry out the study with, and commit to providing a similar class or group for participation in their second year of the study. Inclusion Criteria: * part of the class or group identified by their school * 16 to 19 years old * sufficient English language skills (as assessed by data collector) to take part in the TTHSR intervention Exclusion Criteria: * Under 16 years old * 20 years old or over * Insufficient English language skills (as assessed by data collector) to take part in the Wrap It Up intervention
