Risk factors for ectopic pregnancy in a sub-Saharan African country.

Our case-control study aimed at identifying the risk factors (RFs) for ectopic pregnancy (EP), and was carried out between 1st February and 31st May, 2019. Women who had EP were compared to those without EP. Out of 3421 pregnancies, 93 (2.7%) had EP. Independent RFs were previous EP, past history of infertility, first sexual encounter <15 years, past history of chlamydia infection,  ≥ 3 sexual partners, use of levonorgestrel based emergency contraceptive pill, and unemployment. Girls should be counselled concerning these RFs and specifically against early sexual intercourse and multiple sexual partnership.
