The purpose of this study was to determine the incidence and some risk factors of ectopic pregnancy in Hamadan province during 2000-2010. METHODS: This was a retrospective descriptive study carried out at hospitals in Hamadan provience, Iran. A total of 872 women with the diagnosis of ectopic pregnancy between 2000 to 2010 were recruited. At initial assessment, 872 medical records were targeted for the assessment, while because of incompleteness of some recorded information, 521 files were finally assessed. RESULTS: The overall incidence of ectopic pregnancy was estimated to be 2.6 per 1000 recorded pregnancies. While, considerably increased from 1.5 per 1000 pregnancy in 2000 to 4.8 per 1000 pregnancies in 2010. More than half of the women aged 25 to 34 years. 48.2% of selected women were using contraception methods. 5.2%, 14.0% and 5.6% of women had pervious ectopic pregnancy, first or second infertility and pelvic inflammatory diseases, respectively. CONCLUSION: Increasing trend of the incidence of ectopic pregnancy is expected due to development and availability of minute diagnostic approaches and also some baseline amendable (contraceptive methods and surgical interventions) and unchangeable (age of pregnancy and residency) parameters.
