放疗科护士睡眠障碍及与孤独感的关系

Relationship between sleep disturbance and loneliness in radiotherapy nurses

目的了解放疗科护士睡眠障碍及与孤独感的关系。方法随机选取放疗科护士191例为调查对象,使用匹兹堡睡眠质量指数量表(PSQI)和UCLA孤独量表进行调查,采用多元线性回归分析孤独感对睡眠状况的影响。结果 58.64%(112例)的护士有睡眠障碍。已婚护士PSQI总分及睡眠效率得分(8.55±1.92,1.52±0.99)高于未婚护士(7.81±2.28,1.10±1.06),差异有统计学意义(t=2.435,2.843,均P<0.05)。集体住宿护士PSQI总分及主观睡眠质量和睡眠障碍得分高于在家居住护士,每周夜班≥2次护士主观睡眠质量得分(1.68±0.81)高于≤1次护士(1.36±0.77),大专文化程度护士PSQI总分及日间功能障碍得分(8.43±1.98,1.43±0.86)高于本科及以上护士(7.36±2.41,1.18±0.72),家庭关系较融洽护士PSQI总分及睡眠障碍得分低于家庭关系一般及隔阂多护士。自评压力较轻护士PSQI总分及主观睡眠质量、入睡时间、睡眠时间及日间功能障碍得分低于压力较大护士。年龄30~34岁护士PSQI总分及睡眠障碍和日间功能障碍得分高于<25和25～29岁护士,差异均有统计学意义(P<0.05或P<0.01)。孤独感得分进入PSQI总分的回归方程(β=0.295,P<0.05)。结论放疗科护士睡眠障碍发生率高,其睡眠状况因不同人口学特征而存在差异,孤独感对放疗科护士睡眠状况具有预测关系。

[Objective] To investigate the relationship between sleep disturbance and loneliness in radiotherapy nurses.[Methods ] Using Pittsburgh sleep quality index（PSQI） and UCLA loneliness scale,191 radiotherapy nurses were investigated with random sampling. The effects of loneliness on sleep disturbance were analyzed by multiple linear regression analysis.[Results] 58.64%（112 cases） of participants exhibited clinically relevant sleep disturbances. The total PSQI score and sleep quality score of married nurses（8.55±1.92,1.52±0.99） were higher than those of single nurses（7.81±2.28,1.10±1.06）,and the difference was statistlcally significant（t=2.435,2.843,both P〈0.05）. The total PSQI score and scores of subjective sleep quality and sleep disorders of collective accommodation nurses were significantly higher than those of nurses living at home. The subjective sleep quality score of nurses with night shift frequency more than two times a week（1.68±0.81） was significantly higher than those of nurses with night shift frequency less than one time a week（1.36±0.77）. The total PSQI score and daytime dysfunction score of nurses with university cultural degree（8.43±1.98,1.43±0.86） were significantly higher than nurses with bachelor degree or above（7.36±2.41,1.18±0.72）. The total PSQI scores and sleep disturbance score of the nurses with harmonious family relationship were significantly lower than those of the nurses with disharmony family relationship. The total PSQI scores,and the scores of subjective sleep quality,sleep latency,sleep time and daytime dysfunction of the nurses with lighter self-evaluation pressure were significantly lower than those of the nurses with larger self-evaluation pressure. The total scores of PSQI and the scores of sleep disorders and daytime dysfunction of the nurses aged 30-34 years old were significantly higher than those of the nurses in age groups of 〈25 and 25-29 years old（P〈0.05 or P〈0.01）. Loneliness entered the regression equation of PSQI total score（β=0.295,P〈0.05）.[Conclusion] The incidence of sleep disorders among nurses in radiotherapy department is high,and their sleep quality varies with different demographic characteristics. Loneliness has a positive predictive effect on the sleep quality of the radiotherapy nurses.
