目的研究寻常型银屑病患者的睡眠质量及影响因素。方法对2007年12月-2008年8月在空军总医院皮肤科门诊就诊的126例寻常型银屑病患者进行匹兹堡睡眠质量指数(PSQI)问卷和自编睡眠质量影响因素问卷调查。PSQI统计结果与国内刘贤臣等报道的112例正常成人和45例失眠患者进行对照研究。结果126例寻常型银屑病患者中有75例(59.5%)存在睡眠障碍,69例(54.8%)认为自己的睡眠质量较差,89例(70.6%)认为睡眠质量与银屑病的病情相关。PSQI均值7.35±2.29,在评分≥2分的评测项目中,入睡时间延迟得分最高,其次为日间功能障碍,再次为睡眠障碍。银屑病患者组PSQI总分及各评测项目得分与正常成人组比较均有统计学差异(P<0.01);银屑病患者组与失眠症患者组在PSQI入睡时间和睡眠障碍两个项目上无统计学差异(P>0.05)。结论银屑病患者的睡眠质量较差,应有针对性地对银屑病患者进行心理健康教育,以舒缓压力,改善其睡眠质量。

Objective To investigate the sleep quality of patients with psoriasis vulgaris and related influencing factors. Methods During the period from Dec. 2007 to Aug. 2008, 126 patients with psoriasis vulgaris, who visited the clinics, were investigated with the Pittsburgh sleep quality index （PSQI）. At the same time, a self-designed questionnaire was utilized in order to survey the factors that affect the sleep quality of patients with psoriasis vulgaris. The results of PSQI survey were compared with that reported by Liu Xian-chen＇s in 1996 on 112 cases of normal adults and 45 insomnia patients. Results Seventy-five （59. 5%） out of 126 patients with psoriasis vulgaris were found to have sleep disorder. Sixty-nine patients （54.8%） were self-considered themselves to have poor sleep quality. Eighty-nine patients （70.6%） believed that psoriasis was one of the inducing factors of poor sleep. The mean score of PSQI was 7. 35±2. 29. Among the component items with a score ≥2, delayed sleepiness got the maximum score, followed by shortness of ability in day time and sleep disturbances. The global PSQI score and component scale scores were significantly different between psoriasis patients and normal adults. No significant difference was found between psoriasis patients and insomnia patients in delayed sleepiness and sleep disturbances. Condusions Poor sleep quality does exist in the patients with psoriasis vulgaris. Therefore, comprehensive measures should be taken to improve sleep quality of psoriasis patient. Meanwhile, it is necessary to promote mental health education, easing the patients＇ mental pressure to improve the quality of sleep.
