The pattern of notification and testing for genital Chlamydia trachomatis infection in Victoria, 1998–2000: an ecological analysis

Abstract Objective:This ecological study analyses routinely collected chlamydia notification and testing data to investigate any patterns. Methods:Age and sex‐specific chlamydia notification and testing rates for Victoria were calculated for the period 1998 to 2000. Results:Chlamydia notification and testing rates rose between 1998 and 2000. Notification rates were higher among women aged 15 to 24 years than men of the same age (p<0.01) and higher among 25 to 44‐year‐olds living in metropolitan rather than rural/regional Victoria (p<0.01). Testing rates were higher for women than men (p<0.01) and higher in metropolitan rather than rural/regional areas (p<0.01) in all groups except women aged 15–24 years. Conclusions:These increasing rates highlight that chlamydia infection represents a substantial public health problem. Implications:Although these data provide useful information showing these rates vary with age and sex, formal epidemiological prevalence and risk factor studies are required
