Numerous studies have found evidence of a link between perceived discrimination and unhealthy behavior, especially substance use. Within this body of literature, 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.
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 (Mage = 10.5 at Wave 1), the adolescent's primary caregiver (Mage = 37), and, in some cases, an older sibling of that adolescent (Mage = 13). Wave 1 Ns were 889, 889, and 295, respectively. Healthy behavior was defined as diet and exercise.
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.
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. (PsycInfo Database Record (c) 2021 APA, all rights reserved).
许多研究发现,感知歧视与不健康行为之间存在关联,尤其是物质使用。然而,在这一文献中,有几项研究出人意料地发现,非裔美国人(主要是女性)感知到的种族歧视与某些类型的健康行为之间存在正相关,主要是锻炼和健康饮食。本研究进一步探讨了这种正相关关系,包括一个预期的调节变量:乐观主义。它还研究了感知种族歧视与不健康行为的一个相关因素:身体质量指数(BMI)之间的关系。
在三个相关的非裔美国人样本中,从参与家庭和社区健康研究的家庭中收集了 14 年来的 6 波数据。每个家庭都包括一个青少年(第 1 波时龄为 10.5 岁)、青少年的主要照顾者(时龄为 37 岁),以及在某些情况下,该青少年的一位年长的兄弟姐妹(时龄为 13 岁)。第 1 波的 N 分别为 889、889 和 295。健康行为的定义是饮食和锻炼。
在任何一个样本中,感知种族歧视与 BMI 之间几乎没有长期关系的证据,而且在男性中也没有歧视与健康行为之间的关系。然而,相关分析显示,在所有三组女性中,歧视与健康行为之间存在正向的前瞻性关系;结构方程模型表明,在乐观程度较高的女性中,这种关系更为强烈。
感知种族歧视似乎与非裔美国人的 BMI 无关,但与高特质性乐观的黑人女性的健康行为有关。
