Numerous studies have identified a link between perceived discrimination and unhealthy behavior, although some unexpected evidence of a positive relationship was found between perceived racial discrimination and healthy behavior, especially among Black females, and this relationship was further strengthened by optimism as a moderator. The study showed that perceived racial discrimination is not related to BMI among African Americans, but it does impact healthy behavior among Black females who are high in dispositional optimism.
Objective: Numerous studies have found evidence of a link between perceived discrimination and unhealthy behavior, especially substance use. Within this body of literaiure, however, several studies have found unexpected evidence of a positive relation between perceived racial discrimination among African Americans-mostly women-and certain types of healthy behavior, primarily exercise and healthy eating. The current study further examined this positive relation, including an anticipated moderator: optimism. It also examined the relation between perceived racial discrimination and a correlate of unhealthy behavior: BMI. Method: Six waves of data were collected over 14 years in three related samples of African Americans from families participating in the Family and Community Health Study. Each family included an adolescent (M-age = 10.5 at Wave I), the adolescent's primary caregiver (M-age = 37), and, in some cases, an older sibling of that adolescent (M-age = 13). Wave 1 Ns were 889. 889. and 295, respectively. Healthy behavior was defined as diet and exercise. Results: There was very little evidence of a long-term relation between perceived racial discrimination and BMI in any sample, and no evidence of a relation between discrimination and healthy behavior among the males. However, correlational analyses revealed a positive prospective relation between discrimination and healthy behavior among all three groups of females; structural equation modeling indicated that this relation was stronger among women who were high in optimism. Conclusions: Perceived racial discrimination does not appear to be related to BMI among African Americans. but it is related to healthy behavior among Black females who are high in dispositional optimism.
