Population based study of genital Chlamydia trachomatis prevalence and associated factors in Norway: A cross sectional study

Abstract

BackgroundThe number of diagnosed cases of Chlamydia trachomatis infection has been increasing in the past years in Norway although the testing rate has been relatively stable. The aim of this study was to measure the prevalence of genital Chlamydia trachomatis in young men and women in one county in Norway and determine associated factors in order to better target preventive measures.MethodsWe mailed to a random sample of 10 000 persons aged 18–25 in Rogaland county a mail-back urine sample kit and a self-administered questionnaire with questions on socio-demographic details, health seeking behaviour and symptoms of and history of sexually transmitted diseases. Associations between current Clamydia trachomatis infection and the above mentioned factors were studied by multiple logistic regression.ResultsThe response rate among women was 18.9% (930/4923) and 11.9% (605/5077) among men. The prevalence of Chlamydia trachomatis infection was 5.8% (95% CI 4.5-6.8) among women and 5.1% (95% CI 3.8-6.8) among men. For men a greater number of partners during the last year (p for trend < 0.001), and living in a municipality without a local youth clinic increased the odds of infection (OR 8.6, 95% CI 2.2-33.9). For women a greater number of partners during the last year (p < 0.001) and not having consulted a family doctor for STIs (OR 2.1 95% CI 1.1-4.2) were positively associated with infection while not having a previous Chlamydia trachomatis diagnosis decreased the odds of having this infection (OR 0.3, 95% CI 0.2-0.7).ConclusionOur results indicate the importance of having a visible youth clinic in each municipality. It also suggests targeting women who have had a previous Chlamydia trachomatis infection diagnosed before.

Sexual and testing behaviour associated withChlamydia trachomatisinfection: a cohort study in an STI clinic in Sweden

“…7 9 10 12 22 Younger individuals (20–24 years) had a significant two times higher risk to be diagnosed with chlamydia compared with those 35–40 years, and this was consistent with earlier reports on higher chlamydia risk among younger individuals, which might be attributed to the higher number of sexual partners and lower condom use in the younger individuals, which was supported by descriptive results in our study 67 9 10 Furthermore, study participants who reported contact with a chlamydia case (having a partner with chlamydia or receiving a contact tracing letter) were strongly associated with increased risk of chlamydia. In Sweden, patients with chlamydia are required by the Communicable Disease Act to notify their sexual contacts in order for them to be laboratory tested and thus interrupt further the transmission chain.…”

“…Risk factors for acquiring a CT infection include young age,8 multiple sex partners within the last year,9 not using a condom consistently,10 high alcohol consumption11 and previous CT infection 12. While there is much knowledge about CT risk factors and complications, whether the diagnosis has any impact on patients’ psychological and sexual health is less studied.…”
