Since decades the incidence of ectopic pregnancy has risen in most western countries including four to five folded increased rates, suggesting an "epidemic". Increasing incidences of ectopic pregnancy was reported in Sweden until 1988 and 1989 when a peak of 17.3 cases of ectopic pregnancy/10,000 women in fertile age was registered. Between 1990 and 1991 the incidence decreased from 16.8 to 14.9 cases of ectopic pregnancy/10,000 women. The mortality in Sweden 1985-1991 was 0.15/1000 (3 deaths in 20,486 cases of ectopic pregnancy), the lowest case-fatality rate ever reported.
几十年来,包括发病率增长了四到五倍在内,大多数西方国家宫外孕的发病率都在上升,这表明宫外孕呈“流行”态势。瑞典报告称,直到1988年和1989年宫外孕发病率一直在上升,当时登记的育龄妇女宫外孕发病率达到峰值,为每10000名妇女中有17.3例。1990年至1991年期间,发病率从每10000名妇女中有16.8例降至14.9例。1985年至1991年瑞典的死亡率为每1000人中有0.15人(20486例宫外孕中有3例死亡),这是有史以来报告的最低病死率。
