Chlamydia screening in Sweden reduces the risk of ectopic pregnancy

Genital chlamydial infections cause pelvic inflammatory disease and may lead to ectopic pregnancy and infertility. In Sweden screening for chlamydial infections, contact tracing, and free treatment were introduced in the 1980s. On p 1776 Egger et al examine the impact of these measures on the risk of ectopic pregnancy in Uppsala. Between 1985 and 1995 the rates of chlamydial infections and of ectopic pregnancy declined. There was a strong correlation between the rate of ectopic pregnancy and the rate of chlamydial infection in the same year for women aged 20-24 years. Regression analyses suggest that among young women chlamydial infections are the main cause of ectopic pregnancy.
