Trends of the incidence and mortality associated with ectopic pregnancy (EP) in the United States were examined for 1970 through 1978. The estimated number of EPs rose from 17,800 in 1970 to 42,400 in 1978, and the EP incidence rate rose from 4.5 per 1,000 reported pregnancies to 9.4 during the same time period. ⋯ Over 2.5% of all reported pregnancies among nonwhite women aged 35 to 44 years were ectopic. The death-to-case rate for EP declined almost 75% during the study period but remained consistently higher for nonwhite women as compared with white women.

Data on ectopic pregnancies reported to the New York State Department of Health for upstate residents for the years 1971 through 1979 were analyzed by maternal age, race, and gravidity. Trends in the rate of ectopic pregnancies were also examined for this time period. The rate of ectopic pregnancies per 1,000 conceptions increased with increasing maternal age and was higher for nonwhite women compared with white women. ⋯ The rate of ectopic pregnancies per 1,000 conceptions increased by 217% from 1971 to 1979. This trend differed within subgroups of maternal age, race, and gravidity. The percentage of increase was greater for women 30 years of age or older compared with women 30 years of age or younger, greater for white women compared with nonwhite women, and greater for women with three or more previous pregnancies compared with women with fewer previous pregnancies.
