N2 - Background Chlamydia is the most commonly notified infection in Australia. Prevention strategies should be informed by routine data on at-risk populations. Methods: We calculated chlamydia positivity and correlates of infection using multivariable logistic regression for data collected between April 2006 and June 2009. Results: Chlamydia positivity was 5.6% in 12233 females, 7.7% in 10316 heterosexual males and 6.2% in 7872 men who have sex with men (MSM). Correlates of chlamydia positivity among females included younger age (odds ratio (OR) 2.27, 95% confidence interval (CI) 1.922.69), being born overseas (OR 1.50, 95% CI 1.251.82), multiple sex partners in the past year (OR 1.72, 95% CI 1.402.11) and inconsistent condom use with regular sex partners (OR 3.44 ,95% CI 1.657.20). Sex work was protective for females (OR 0.68, 95% CI 0.530.86). Among heterosexual males, correlates of positivity were younger age (OR 1.87, 95% CI 1.622.17), being born overseas (OR 1.35, 95% CI 1.161.58), symptoms at the time of testing (OR 1.64, 95% CI 1.401.92) and multiple sex partners in the past year (OR 1.83, 95% CI 1.462.30). Correlates of positivity among MSM were being born overseas (OR 1.23, 95% CI 1.001.51), being HIV-positive (OR 1.80, 95%CI 1.322.47), and reporting six or more anal sex partners in the past 6 months (OR 4.45, 95% CI 1.3714.5). Conclusions: Our analysis identified subgroups at the highest risk of chlamydia in VICtoria. These estimates will provide important baseline information to measure the impact of chlamydia control strategies.
