The explanation for the substantial decline in stroke death rates can be investigated only by measuring trends in stroke incidence and case-fatality.
Two community-based studies carried out in Auckland, New Zealand, in 1981 and 1991 used comparable methods and definitions, met criteria for well-designed studies, and had the power to detect small changes in incidence and case-fatality rates, 703 events (representing 50% of all strokes) were registered in 1981 and 1735 events in 1991. 521 (74.1%) and 1255 (72.3%) events in 1981 and 1991, respectively, were first-ever (in a lifetime) strokes.
Although there was no change in overall stroke incidence between 1981 and 1991, there were changes in age and sex groups.
