Population attributable fraction of pelvic inflammatory disease associated with chlamydia and gonorrhoea: A cross-sectional analysis of Australian sexual health clinic data

Abstract

Objectives Pelvic inflammatory disease (PID) is an important cause of female infertility and can occur when micro-organisms such as chlamydia or gonorrhoea ascend to the upper genital tract. PID has been used as an outcome measure in chlamydia screening trials; however, few data have quantified the PID burden that could be avoided by preventing chlamydia. We estimated the population attributable fraction (PAF) of PID associated with a current chlamydia or gonorrhoea infection among females 16-49years attending an Australian sexual health clinic (SHC) (2006-2013). Methods Using multivariable logistic regression, PAF estimates were adjusted for age and behavioural factors. Two separate analyse..
