Abstract: The annual trends in blood pressure levels and prevalence of hypertension classified by JNC-5 were investigated. This survey was conducted retrospectively in a large cohort of Nagasaki atomic bomb survivors (78, 323 persons in 1971) over 20 years. In the age-sex specific groups from the 30's to the 90's, the levels of mean SBP decreased in the latter 10 years compared to the former 10 years except in males in the 30's and the mean DBP decreased except in both sexes in the 30's. The annual trends in age-sex specific mean SBP and DBP were observed in a significant downward fashion and the most conspicuous depletion was shown at the age 80's in males, 8.3 mmHg per 10 years for SBP and 3.0 mmHg per 10 years for DBP. The prevalence of high blood pressure has decreased. The depletion was most striking in the severe (stage 3) and very severe (stage 4) groups of JNC-5 classification. In all sex-age groups, the proportion of stage 3 decreased to the level below one-third or even one quarter compared to the maximum rate in the study period. The depletion of the stage 4 group was most conspicuous, for example, from 3 % in 1975 to 0.38 % in 1989 in the 80's male group.
