J. Makinen et al., A LINK BETWEEN THE EPIDEMIC OF ECTOPIC PREGNANCY AND THE BABY-BOOM COHORT, American journal of epidemiology, 148(4), 1998, pp. 369-374
In order to demonstrate the detailed profile of the recent epidemic of
ectopic pregnancy and the subsequent decrease of the disease, the aut
hors analyzed the changes in 5-year age groups and by 5-year age cohor
ts in Finland. The results describe a link between the epidemic of ect
opic pregnancy and the so-called ''baby boom'' cohort (from 1945 to 19
54) in the 1970s and 1980s, when these large age groups were in their
most fertile period. The authors conclude, through its risk factors, t
hat ectopic pregnancy is strongly correlated with age and that it exem
plifies how the changes caused by large age groups play a role in the
rise and fall in occurrence of certain diseases.
