Abstract
To get information about secular trend of age-specific incidence rate, cumulative incidence up to 5 years of age, and whether there is a cohort effect of incidence rate of Kawasaki disease, we analyzed the data of nationwide incidence surveys of the disease in Japan from 1970 through 1990. The age-specific incidence rate increased gradually except for three nationwide epidemic years. Cumulative incidence from birth through 4 years of age also increased, and was about 0.5% for males and 0.4% for females who were born in early and middle 1980's. Although some birth cohort showed a high relative risk of incidence rate with statistical significance, there was no meaningful cohort effect on Kawasaki disease. J Epidemiol, 1994; 4 : 13-16.
