Emerging evidence suggests Chinese breast cancer survivors, a largely understudied population, are at increased risk of sleep disturbance which can have significant impacts on quality of life and other important outcomes. This study aims to describe sleep disturbance among Chinese breast cancer survivors and to examine demographic and clinical correlates as well as psychosocial correlates of sleep disturbance.
Data from 80 Chinese breast cancer survivors in the USA completed the Chinese version of the Pittsburgh Sleep Quality Index as well as measures of quality of life, depressive symptoms, and perceived stress. Participants also completed measures of demographic factors and acculturation.
Two thirds (66%) of survivors experienced elevated sleep disturbance. Approximately half (49%) reported sleep efficiency, the percentage of time in bed that is spent asleep, that was below the recommended cutoff. Compared to those without sleep disturbance, those with sleep disturbance had worse quality of life, more depressive symptoms, and more perceived stress (ps ≤ .01).
This study is among the first to examine sleep disturbance among any Asian cancer population in the USA. Findings indicate Chinese breast cancer survivors may experience significant disparities in sleep disturbance relative to non-Hispanic Whites and suggest an urgent need for interventions to address sleep disturbance among Chinese breast cancer survivors.
越来越多的证据表明，中国乳腺癌幸存者这一人群在很大程度上尚未得到充分研究，他们存在睡眠障碍的风险增加，这可能对生活质量和其他重要结果产生重大影响。本研究旨在描述中国乳腺癌幸存者的睡眠障碍，并探讨睡眠障碍与人口统计学和临床相关因素以及心理社会相关因素的关系。
来自美国的 80 名中国乳腺癌幸存者完成了匹兹堡睡眠质量指数的中文版本以及生活质量、抑郁症状和感知压力的测量。参与者还完成了人口统计学因素和文化适应的测量。
三分之二（66%）的幸存者经历了睡眠障碍。大约一半（49%）的人报告说，他们的睡眠效率，即在床上入睡的时间百分比，低于建议的截止值。与没有睡眠障碍的人相比，有睡眠障碍的人生活质量更差，抑郁症状更多，感知压力更大（p≤0.01）。
这项研究是在美国首次对任何亚洲癌症人群的睡眠障碍进行的研究之一。研究结果表明，中国乳腺癌幸存者在睡眠障碍方面可能与非西班牙裔白人存在显著差异，这表明迫切需要采取干预措施来解决中国乳腺癌幸存者的睡眠障碍问题。
