OBJECTIVES
To compare health risks in 84 healthy African American and 45 white men and women after calculating allostatic load (AL) from biologic, psychosocial, and behavioral measures.
METHODS
Participants (18-45 years) ranging in weight from normal to obese and without hypertension or diabetes. Fitness, body fat, CRP, mood, social support, blood pressure, sleep and exercise habits, coping, and insulin responses were dichotomized as low/high risk and summed for AL.
RESULTS
African Americans (3.4±1.9) had significantly higher AL than that of whites (2.4±1.9; P<0.05). Significantly more African Americans had AL≥3 (67.9%) than did whites (48.9%).
CONCLUSIONS
Identifying cumulative AL may help identify and address the underpinnings of health disparities in African Americans.
目的
通过从生物学、心理社会和行为指标计算应激负荷（AL），比较84名健康非裔美国人和45名白人男性及女性的健康风险。
方法
参与者年龄在18至45岁之间，体重范围从正常到肥胖，且无高血压或糖尿病。将身体适应性、体脂、C反应蛋白、情绪、社会支持、血压、睡眠和运动习惯、应对方式以及胰岛素反应分为低/高风险，并汇总计算AL。
结果
非裔美国人的AL（3.4±1.9）显著高于白人（2.4±1.9；P<0.05）。AL≥3的非裔美国人（67.9%）明显多于白人（48.9%）。
结论
识别累积的AL可能有助于识别和解决非裔美国人健康差异的潜在因素。
