白噪音干预对改善高原军人主观睡眠质量和焦虑情绪的效果

  目的   探讨白噪音对改善高原军人主观睡眠质量和焦虑情绪的疗效和安全性。  方法   在海拔3 800 m的驻军某部，采用匹兹堡睡眠测评量表（PSQI量表）、焦虑自评量表（SAS）、Epworth嗜睡量表（ESS）对驻高原官兵进行问卷调查。对符合纳入标准的受试者按1∶1随机分为试验组和对照组进行开放性对照试验。试验组进行每天2次，每次30 min的白噪音干预，对照组不采用任何干预措施。连续3个月后再次进行PSQI、SAS、ESS评分。  结果   共获取423份有效筛查问卷，睡眠障碍（PSQI≥5分）者占比59.21%，焦虑（SAS≥50分）检出率43.97%，嗜睡（ESS≥7分）者占比68.88%。共有40人参加对照试验。完成3个月的白噪音干预后，两组PSQI评分和SAS（P = 0.026）有显著性差异，但ESS评分差异无统计学意义（P = 0.055）。  结论   白噪音干预对提高高原官兵主观睡眠质量和缓解焦虑情绪有积极作用。

The Effectiveness of White Noise Intervention for Improving Subjective Sleep Quality and Anxiety of Militaries Living at the High Altitude

  Objective  To explore the efficacy and safety of white noise on improving the subjective sleep quality of soldiers in plateaus.   Methods  At a garrison of 3,800 meters, the Pittsburgh Sleep Assessment Scale （PSQI scale）, anxiety self-assessment scale （SAS）, and Epworth sleepiness scale （ESS scale） were used. Subjects meeting the inclusion criteria were randomized by 1∶1 into the trial and control groups for an open control trial.The trial group had a 30-min white noise intervention twice daily, while no intervention was used in the control group. The PSQI, SAS, and ESS scores were performed again after 3 consecutive months.   Results  A total of 423 valid screening questionnaires were obtained, with 59.21% of dyssomnia （PSQI≥5）, anxiety （SAS≥50） detected at 43.97%, and 68.88% of drowsiness （ESS≥7） detected. A total of 40 participants participated in the controlled trial. After the completion of the 3-month white noise intervention, the PSQI scores （P = 0.001） and SAS scores （P = 0.026） were significantly different, but there was no significant difference in the ESS scores.   Conclusion  White noise intervention has a positive effect on improving the subjective sleep quality and relieving the anxiety of soldiers in plateaus.
