Relationship between personality traits and health behavior among working women in Japan

Abstract

Considering personality traits is effective for cultivating health promotion habits. Therefore, individualized interventions that account for personality traits would be more beneficial for modifying health behaviors. The present study describes the relationship between personality traits and health behaviors among working women compared with non-working women in Japan. Secondary analysis was conducted using nationally representative data from the Japanese Household Panel Survey (JHPS/KHPS). In the 2019 wave, data were gathered from 1,141 women (939 who were working and 202 who were not) between the ages of 28 and 65. Associations among health behaviors, personality traits, and employment status were confirmed by phi coefficient and coefficient ratio. Logistic regression analysis was conducted to examine the association between health behaviors and personality traits. As for working women, daily fruit consumption was associated with extraversion (odds ratio [OR], 1.197; p = 0.003) and conscientiousness (OR, 1.238; p = 0.032). Conscientiousness has been found to significantly contribute to low-risk alcohol consumption (OR, 1.213; p = 0.035). Desirable physical activity habit was associated with extraversion (OR, 1.312; p = 0.000). In contrast, among non-working women, desirable physical activity habits was associated with extraversion (OR, 1.573; p = 0.007) and neuroticism (OR, 0.390; p = 0.001). Further research is needed to clarify the mechanisms underlying differences between working women and non-working women in the association between health behaviors and personality.
