Abstract
In order to investigate the indices of aging, a mass examination was undertaken in 1963 on subjects (724 males, 1239 females, more than 65 years of age, who live in the Tokyo Metropolitan Home for the aged).
The results obtained were as follows:
1) Arcus senilis which was found more frequently according to age was considered to be a good index of aging.
2) Nocturnal frequency of micturition also increased in the advanced aged of both sexes, and this tendency was more marked in females than males.
3) Modified Broca's index become lower with aging in females, while no remarkable change was observed in males. Skin fold also showed some tendencies, and it was considered to be a better indicator than the modified Broca's index.
4) Systolic blood pressure tended to rise with increasing age, while diastolic blood pressure did fall. These tendencies were significant in females.
5) Electrocardiographic findings which reflected aging process were ST-T abnormalities, right bundle branch block, P-Q prolongation, atrial fibrillation, and left axis deviation. ST-T abnormality was the best index of all findings.
