Ectopic pregnancy (EP) is a rare adverse outcome in which a fertilized egg implants and develops outside of the uterus. Life-threatening cases of EP among deployed U.S. service members have been described. During 2002- 2011, among active component females younger than 49, 1,245 EPs were diagnosed and treated as indicated by diagnostic and procedure codes recorded in electronic medical records. Annual numbers of EPs ranged from 91 to 151. During the period EP affected 0.64 percent of all pregnancies, with higher proportions among servicewomen in their 30s and of black, non-Hispanic race/ ethnicity. As compared with civilians, service members had the same percentage of pregnancies that were ectopic but had lower proportions of EPs that were treated medically (with methotrexate) rather than surgically.
异位妊娠（EP）是一种罕见的不良结局，即受精卵在子宫外着床并发育。已报道过部署在美国的现役军人中出现危及生命的异位妊娠病例。在2002年至2011年期间，在49岁以下的现役女性中，根据电子病历中记录的诊断和程序代码，有1245例异位妊娠被诊断并接受了相应治疗。异位妊娠的年病例数在91至151例之间。在此期间，异位妊娠占所有妊娠的0.64%，30多岁的女性军人以及黑人、非西班牙裔种族/族裔的女性军人中异位妊娠的比例更高。与平民相比，军人中异位妊娠的比例相同，但药物治疗（使用甲氨蝶呤）而非手术治疗的异位妊娠比例较低。
