Trends in ectopic pregnancy in Canada.
The incidence in Canada of one complication of sexually transmitted disease, ectopic pregnancy, was examined by age group for the years 1971 through 1980 by means of hospital statistics provided by Statistics Canada. The denominator was "reported pregnancies"--the total of live births, stillbirths, legal abortions and ectopic pregnancies in a given year. In 1980, 4123 ectopic pregnancies (9.3/1000 reported pregnancies) were reported, a 63% increase from 1970. The incidence had increased in each age stratum. This trend may be related to increasing rates of gonococcal infection and of hospitalization for pelvic inflammatory disease and lends confirmation to data from other countries that relate the increase in the rate of ectopic pregnancy to rising rates of sexually transmitted disease.
