We assessed cross-sectional differences in sleep quality and risk factors among Asian, Black, Latino, and White participants in the Kaiser Healthy Aging and Diverse Life Experiences (KHANDLE) Study.
KHANDLE enrolled community-dwelling adults aged ≥65 years living in northern California. Participants completed a modified Pittsburgh Sleep Quality Index to measure six sleep components and a global sleep score (scored 0-24). Covariates included age, sex, central adiposity, education, income, alcohol consumption, ever smoking, physical activity, and depression. Ordinal logistic regression was used to model sleep component scores across race/ethnic groups. Linear regression was used to assess racial/ethnic differences in global sleep score and the association between risk factors and global sleep score.
1,664 participants with a mean age of 76 (SD=7) and mean global sleep score of 6 (SD=4) were analyzed. Using Latinos as reference (highest average sleep score), Blacks had an average .96 (.37, 1.54) unit higher global sleep score (worse sleep) while Asians [: .04 (-.56, .63)] and Whites [: .28 (-.29, .84)] did not significantly differ. Compared with Latinos, Blacks and Asians had greater odds of a worse score on the sleep duration component; Blacks and Whites had greater odds of a worse score on the sleep disturbances component; and, Whites had greater odds of a worse score on the medication component. Risk factors for poor sleep did not differ by race/ethnicity except alcohol consumption (interaction P=.04), which was associated with poor sleep in Blacks only.
In this cohort, racial/ethnic differences in sleep quality were common.
我们评估了 Kaiser 健康老龄化和多样化生活体验（KHANDLE）研究中亚洲人、黑种人、拉丁裔和白种人参与者的睡眠质量和风险因素的横断面差异。
KHANDLE 招募了居住在加利福尼亚州北部的 65 岁及以上的社区居民。参与者完成了改良的匹兹堡睡眠质量指数，以测量六个睡眠成分和一个整体睡眠评分（评分 0-24 分）。协变量包括年龄、性别、中心性肥胖、教育程度、收入、饮酒、吸烟史、身体活动和抑郁。有序逻辑回归用于对种族/族裔群体的睡眠成分评分进行建模。线性回归用于评估整体睡眠评分的种族/族裔差异以及风险因素与整体睡眠评分之间的关联。
分析了 1664 名参与者，平均年龄为 76（SD=7）岁，平均整体睡眠评分为 6（SD=4）。以拉丁裔为参考（平均睡眠评分最高），黑种人整体睡眠评分平均高出.96（37，1.54）分（睡眠质量更差），而亚洲人[：.04（-56，63）]和白人[：.28（-29，84）]差异无统计学意义。与拉丁裔相比，黑人和亚洲人在睡眠持续时间成分上更有可能获得较差的评分；黑人和白人在睡眠障碍成分上更有可能获得较差的评分；而白人在药物成分上更有可能获得较差的评分。除了饮酒（交互 P=.04），风险因素与种族/族裔差异对睡眠质量的影响不同，饮酒与黑人的睡眠质量差有关。
在本队列中，睡眠质量的种族/族裔差异很常见。
