Recruitment & Eligibility

• Status: Recruiting
• Sex: Not specified
• Target Recruitment: 315

Inclusion Criteria

All young persons from 16 to 29 years old, registered in the municipal register in Amsterdam, Rotterdam and part of South Limburg (Parkstad, around Heerlen). In Amsterdam and Rotterdam where the population is dense, all sexually active people are encouraged to participate, but in South Limburg where the population is less dense, eligibility for screening depends on the individual’s score on a questionnaire (including e.g. sexual history, residence area, ethnic background, and symptoms) related to the expected Chlamydia risk.

Exclusion Criteria

Excluded are persons younger than 16 years or older than 29 years and persons living outside the 3 trial regions. In South Limburg individuals with a low score on the selection questionnaire can not proceed further with participation (i.e. requesting a chlamydia test kit).

Study & Design

• Study Type: Interventional
• Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
Participation rate and positivity rate, per block of clusters in the three regions, comparing the intervention and control blocks per region, after multiple screening invitations. Estimated population prevalence based on positivity rates and participant profile.

Secondary Outcome Measures

Name	Time	Method
Acceptability and reasons for non-response; reinfection rates at 6 months after initial Chlamydia infections. Process indicators, such as time to participation, response after reminders.
