Association Between Anger and Mortality in Women and Men: A Prospective Cohort Study in a Japanese Community

Abstract

Background:

Anger is a common problem in society, and anger's relationship with mortality, in particular with cardiovascular mortality, has been studied mainly in male western population. There are no prospective studies in Japan, about the association between anger and mortality.

Materials and Methods:

This study examined the association of anger with all-cause and cause-specific mortality in a Japanese community. Data came from the Takayama Study, which recruited residents aged ≥35 years in 1992 from Takayama City in Gifu, Japan. The current study used information on anger that was obtained from the second survey in 2002. A total of 11,902 healthy participants aged ≥45 years completed a self-administered questionnaire. Anger was assessed using the Spielberger Trait Anger Scale.

Results:

The main causes of deaths during the follow-up period from 2002 to 2013 were 460 for neoplasm, 254 for cardiovascular, and 435 for other causes. After adjusting for potential confounders, we found a significant positive association between the trait anger score and the risk of cardiovascular mortality for women, with a hazard ratio for high versus low score of trait anger of 1.81 (95% confidence interval 0.91–3.63, p for trend = 0.04), but not for men.

Conclusions:

Data suggest that for Japanese women, high trait anger score may be associated with an increased risk of cardiovascular mortality. Potential gender differences in the association between trait anger and mortality should be further studied from the cultural context.
