Background. Limited research has been conducted on the moderating effect of race/ethnicity on objective sleep disturbances in breast cancer survivors (BCSs). Objective. To explore racial/ethnic differences in objective sleep disturbances among BCSs and their relationship with self-reported symptoms. Intervention/Methods. Sleep disturbance and symptoms were measured using actigraphy for 72 hours and self-reported questionnaires, respectively, among 79 BCSs. Analysis of covariance, Pearson's correlation, and multivariate regression were used to analyze data. Results. Sixty (75.9%) participants listed their ethnicity as white, non-Hispanic and 19 (24.1%) as minority. Total sleep time was 395.9 minutes for white BCSs compared to 330.4 minutes for minority BCSs. Significant correlations were seen between sleep onset latency (SOL) and depression, SOL and fatigue, and sleep efficiency (SE) and fatigue among minority BCSs. Among white BCSs, significant correlations were seen between SE and pain and wake after sleep onset (WASO) and pain. The association between depression and SOL and fatigue and SOL appeared to be stronger in minority BCSs than white BCSs. Conclusions. Results indicate that white BCSs slept longer than minority BCSs, and race/ethnicity modified the effect of depression and fatigue on SOL, respectively. Implications for Practice. As part of survivorship care, race/ethnicity should be included as an essential component of comprehensive symptom assessments.
背景。关于种族/族裔对乳腺癌幸存者（BCS）客观睡眠障碍的调节作用的研究有限。目的。探讨BCS中客观睡眠障碍的种族/族裔差异及其与自我报告症状的关系。干预/方法。分别使用活动记录仪测量79名BCS的72小时睡眠障碍情况，并通过自我报告问卷收集症状信息。采用协方差分析、Pearson相关性分析和多元回归分析数据。结果。60名（75.9%）参与者将其种族列为非西班牙裔白人，19名（24.1%）为少数族裔。白人BCS的总睡眠时间为395.9分钟，而少数族裔BCS为330.4分钟。少数族裔BCS的睡眠起始潜伏期（SOL）与抑郁、SOL与疲劳以及睡眠效率（SE）与疲劳之间存在显著相关性。在白人BCS中，SE与疼痛以及睡眠后觉醒（WASO）与疼痛之间存在显著相关性。少数族裔BCS中抑郁与SOL以及疲劳与SOL之间的关联似乎比白人BCS更强。结论。结果表明白人BCS的睡眠时间比少数族裔BCS长，并且种族/族裔分别改变了抑郁和疲劳对SOL的影响。对实践的启示。作为幸存者护理的一部分，种族/族裔应作为综合症状评估的重要组成部分。
