Abstract

Higher levels of positive affect have been associated with better physical health. While positive affect is seen as highly desirable among Westerners, East Asians tend to deemphasize positive affect. Using large probability samples of Japanese and U.S. adult populations, the present study examined the relations of positive affect with serum lipid profiles, known to be strongly predictive of risk for cardiovascular disease, and tested whether their associations depend on cultural contexts. As predicted, positive affect was associated with healthier lipid profiles for Americans but not for Japanese. Further analyses showed that this cultural moderation was mediated by body mass index. This study highlights the role of culture in the link between positive emotions and key biological risk factors of cardiovascular disease.
