与非西班牙裔白人成年人相比，美国印第安人患心血管疾病的风险更高。很少有研究检查与这些风险相关的潜在生理和心理机制。本研究旨在探讨健康的美国印第安人和非西班牙裔白人成人心血管疾病风险可能的心理和生理应激相关机制。40名美国印第安人（60%为女性，平均年龄19.93岁，SD = 2.08岁）和45名非西班牙裔白人（70%为女性，平均年龄20.18岁，SD = 2.22岁）参与者参加了面对面的实验室会议。唾液皮质醇和心血管活动在进行10分钟的心算任务之前（基线）、期间和之后进行了测量。与非西班牙裔白人受试者相比，美洲印第安人唾液皮质醇水平降低
American Indian adults are at an increased risk for cardiovascular disease compared with non-Hispanic white adults. Scant research exists examining the underlying physiological and psychological mechanisms associated with these risks. This study aimed to examine possible psychological and physiological stress-related mechanisms related to cardiovascular disease risk in healthy American Indian and non-Hispanic white adults. Forty American Indian (60% female, Mean age = 19.93, SD = 2.08 years) and 45 non-Hispanic white (70% female, Mean age = 20.18, SD = 2.22 years) participants attended an in-person laboratory session. Salivary cortisol and cardiovascular activity were measured before (baseline), during, and after exposure to a 10-minute mental arithmetic task. Compared to non-Hispanic white participants, American Indian had diminished salivary cortisol (p
