Aim: To estimate the prevalence of self-reported sexually transmitted infections (STIs) and examine the associations between self-reported STIs and sociodemographic and behavioral factors among sexually active Slovenians aged 18-49 years.
Methods: Data were collected during 1999-2001 from a probability sample of the general population at respondents' homes by a combination of face-to-face interviews and anonymous self-administered questionnaires. Statistical methods for complex survey data were used to account for stratification, clustered sampling, and weighing.
Results: The proportion of sexually active Slovenian population that reported ever being diagnosed with an STI, excluding pelvic inflammatory disease and vaginal discharge for women, was 5.5% for men and 5.1% for women. Gonorrhea was the most commonly self-reported STI among men (3.7%) and hepatitis B among women (1.7%). Independent risk factors associated with self-reported STIs included having concurrent heterosexual relationships during lifetime [adjusted odds ratio (AOR) for men 3.3 (CI 1.3-8.6) and for women 2.3 (CI 1.0-5.3)], ever having paid for sex for men (AOR 4.0, CI 1.5-10.7), and having at least 10 lifetime heterosexual partners for women (AOR 4.7, CI 1.7-13.0).
Conclusion: Our estimates of lifetime prevalence of self-reported STIs in a probability sample of Slovenian men and women aged 18 to 49 indicate a substantial national burden of STIs. The results could be used in shaping national STI prevention and control policies and strategies. Identification of risk factors associated with self-reported STIs provide a basis for targeting prevention and control efforts to individuals at higher risk.
