The relationships of a rationality/antiemotionality personality scale to mortalities of cancer and cardiovascular disease in a community population in Japan

J Psychosom Res. 2004 Jan;56(1):103-11. doi: 10.1016/S0022-3999(03)00046-1.


Objective: Grossarth-Maticek et al. reported that an individual's level on a rationality/antiemotionality (R/A) personality was strongly predictive of cancer, ischemic heart disease and stroke mortality. To investigate the relationships of an individual's level on the R/A personality to cancer and cardiovascular disease mortality in Japan, we conducted a population-based cohort study.

Method: A self-administered questionnaire was distributed to 36990 Japanese residents in September 1992. The response rate was 90.3%. Data from 13226 males and 14880 females were analyzed. Dates and causes of death through December 31, 1999 were obtained for deceased participants.

Results: The results from multivariate hazard ratios (HRs) revealed that males scoring in the middle level compared to those scoring in the lower level of the R/A personality scale decreased their risk of death from cancer and cardiovascular diseases after controlling for covariates.

Conclusions: The level on the R/A personality scale may affect mortality from cancer and cardiovascular diseases differently in Japan.
