背景:解释痴呆风险中种族/民族差异的途径被低估。 研究方法:我们使用一系列考克斯比例风险和广义结构方程模型(GSEM)研究了英国生物银行研究受访者(50-74岁,N = 323,483; 3.6%非白人少数民族)中的这些差异及其相关途径。结果:在≤15年后,诊断出5,491例全因痴呆病例。少数种族状态(RACE_ETHN,非白色vs.白色)使痴呆风险增加24%(HR = 1.24,95% CI:1.07-1.45,P = 0.005),社会经济地位(SES)减弱了这种关联(HR = 1.12,95% CI:0.96-1.31)。总的种族痴呆效应通过SES和生活必需8生活方式分项评分(LE 8LIFESTYLE)介导,结合饮食,吸烟,体力活动和睡眠因素。SES与痴呆风险呈负相关(HR = 0.69,95% CI:0.67,0.72,P < 0.001)。解释少数民族中痴呆症风险过高的途径包括“种族_民族(−)→社会经济地位(−)→痴呆”,“种族_民族(−)→社会经济地位(−)→认知能力差,认知能力(+)→痴呆”和“种族_民族(−)→社会经济地位(+)→生活方式(−)→痴呆”。结论:在未来的干预措施之前,生活方式因素,包括饮食,吸烟,体育活动和睡眠,对于减少痴呆症的种族和社会经济差异至关重要。
Background: Pathways explaining racial/ethnic disparities in dementia risk are under-evaluated. Methods: We examine those disparities and their related pathways among UK Biobank study respondents (50–74 y, N = 323,483; 3.6% non-White minorities) using a series of Cox proportional hazards and generalized structural equations models (GSEM). Results: After ≤15 years, 5,491 all-cause dementia cases were diagnosed. Racial minority status (RACE_ETHN, Non-White vs. White) increased dementia risk by 24% (HR = 1.24, 95% CI: 1.07–1.45, P = 0.005), an association attenuated by socio-economic status (SES), (HR = 1.12, 95% CI: 0.96–1.31). Total race-dementia effect was mediated through both SES and Life’s Essential 8 lifestyle sub-score (LE8LIFESTYLE), combining diet, smoking, physical activity, and sleep factors. SES was inversely related to dementia risk (HR = 0.69, 95% CI: 0.67, 0.72, P < 0.001). Pathways explaining excess dementia risk among racial minorities included ‘RACE_ETHN(−) → SES(−) → DEMENTIA’, ‘RACE_ETHN(−) → SES(−) → Poor cognitive performance, COGN(+) → DEMENTIA’ and ‘RACE_ETHN(−) → SES(+) → LE8LIFESTYLE(−) → DEMENTIA’. Conclusions: Pending future interventions, lifestyle factors including diet, smoking, physical activity, and sleep are crucial for reducing racial and socio-economic disparities in dementia.
