Objective: To evaluate the effectiveness of a structured information campaign aiming to recruit young adults for a Chlamydia trachomatis test by use of a non-invasive, home obtained and mailed sample.
Methods: All individuals aged 21-23 living in Aarhus county, Denmark (30 000 young adults) were offered a mailed home sampling test for C trachomatis as part of a structured 14 week information campaign on chlamydia. The kit for home sampling could be requested by leaving a message on an answering machine or through a website on the internet.
Results: During the campaign 119 of 15 000 women (0.8%) and 64 of 15 000 men (0.4%) were tested. Prevalence of infection was 8.4% (10/119) and 7.8% (5/64) in females and males, respectively. Four infections in women (4/10=40%) and three infections in men (3/5=60%) were asymptomatic.
Conclusions: The mass media campaign had only a limited effect, and there is a need for more effective outreach programmes to recruit young asymptomatic individuals for C trachomatis testing.
