本研究旨在调查基于正念的乳腺癌康复疗法（MBSR(BC)）对乳腺癌幸存者（BCS）客观和主观睡眠参数的多种测量指标的影响。
采用双臂随机对照设计收集数据，研究对象为参与为期六周的MBSR(BC)项目或常规护理（UC）组的乳腺癌幸存者，并进行为期12周的随访。本次分析是更大规模的母试验（ClinicalTrials.gov标识符：NCT01177124）的一个子集。79名乳腺癌幸存者参与者（平均年龄57岁，分期为0 - III期）被随机分配到正式的（课堂式）为期六周的MBSR(BC)项目组或常规护理组。在基线、完成MBSR(BC)或UC项目后的六周和12周时，对主观睡眠参数（SSP）（即睡眠日记和匹兹堡睡眠质量指数（PSQI））和客观睡眠参数（OSP）（即活动记录仪数据）进行测量。
结果显示，在12周时，MBSR(BC)对客观睡眠参数有积极影响的迹象，表现为睡眠效率（MBSR(BC)组为78.2%，UC组为74.6%，p = 0.04）、睡眠时间百分比（MBSR(BC)组为81.0%，UC组为77.4%，p = 0.02）以及觉醒次数更少（MBSR(BC)组为93.5次，UC组为118.6次，p < 0.01）。从基线到6周，MBSR(BC)组的主观睡眠参数有小幅非显著改善（PSQI总分，p = 0.09）。MBSR(BC)练习的时长与主观睡眠参数或客观睡眠参数之间未观察到显著关系。
这些数据表明，MBSR(BC)可能是一种改善乳腺癌幸存者客观和主观睡眠参数的有效治疗方法。
The purpose of this study was to investigate the effects of MBSR(BC) on multiple measures of objective and subjective sleep parameters among breast cancer survivors (BCS). Data were collected using a two-armed randomized controlled design among BCS enrolled in either a six week MBSR(BC) program or a Usual Care (UC) group with a 12-week follow-up. The present analysis is a subset of the larger parent trial (ClinicalTrials.gov Identifier: NCT01177124). Seventy-nine BCS participants (mean age 57 years), stages 0-III, were randomly assigned to either the formal (in-class) six week MBSR(BC) program or UC. Subjective sleep parameters (SSP) (i.e., sleep diaries and the Pittsburg Sleep Quality Index (PSQI)) and objective sleep parameters (OSP) (i.e., actigraphy) were measured at baseline, six weeks and 12 weeks after completing the MBSR(BC) or UC program. Results showed indications of a positive effect of MBSR(BC) on OSP at 12 weeks on sleep efficiency (78.2% MBSR(BC) group vs. 74.6% UC group, p=0.04), percent of sleep time (81.0% MBSR(BC) vs. 77.4% UC, p=0.02) and less number waking bouts (93.5 in MBSR(BC) vs. 118.6 in the UC group, p<0.01). Small non-significant improvements were found in SSP in the MBSR(BC) group from baseline to 6 weeks (PSQI total score, p=0.09). No significant relationship was observed between minutes of MBSR(BC) practice and SSP or OSP. These data suggest that MBSR(BC) may be an efficacious treatment to improve objective and subjective sleep parameters in BCS.
