摘要
目的:探讨失眠症患者睡眠结构改变与状态焦虑和特质焦虑的关系。方法:对31例失眠症患者和20例正常对照者进行状态-特质焦虑问卷调查和整夜多导睡眠图描记,失眠症组于症状缓解出院后3～4月回访时重复检查。结果:(1)在睡眠结构上,与对照组相比,失眠症组呈现睡眠时间减少[(333.71±84.33)min vs.(403.65±19.29)min]、睡眠效率下降[(70.41±17.35)%vs.(83.45±4.42)%]、睡眠潜伏期[(39.48±24.24)min vs.(19.65±8.57)min]和快速眼动睡眠潜伏期延长[(106.60±42.89)min vs.(86.80±12.25)min],S_1睡眠时间比例增加[(25.36±14.22)%vs.(8.86±1.77)%]、觉醒次数增多[(4.45±2.51)vs.(1.75±1.07)]。S_(3+4)睡眠[(7.38±9.70)%vs.(13.78±4.24)%]和快速眼动睡眠时间比例[(14.54±5.61)%vs.(19.18±2.14)%]减少(Ps<0.05)。(2)在状态-特质焦虑问卷评分上,失眠症组状态焦虑[(47.94±8.96)vs.(39.15±4.51)]和特质焦虑[(49.94±8.90)vs.(42.05±7.13)]得分均高于对照组(Ps<0.05)。状态焦虑与睡眠潜伏期、快眼动睡眠潜伏期、觉醒次数和S_1睡眠时间比例均呈正相关(r=0.25～0.44,Ps<0.05),而与快眼动睡眠时间比例呈负相关(r=-0.41,P<0.01);特质焦虑与睡眠潜伏期和觉醒次数正相关(r=0.37,0.29;均Ps<0.05)。(3)回访时患者睡眠结构改善,状态焦虑得分下降,特质焦虑无明显变化。结论:失眠症患者有明显的睡眠结构改变和较高的状态焦虑和特质焦虑,其睡眠结构改变与状态焦虑和特质焦虑相关。
Objective： To explore the relationship between sleep structure changes and state or trait anxiety in patients with insomnia. Methods： Investigations were conducted with the State-trait Anxiety Inventory （STAI） and whole-night ploysomnography （PSG） recorded in 31 patients with insomnia and 20 normal controls. Repeated examinations were conducted in return visits 3 -4 months after discharge. Results： Compared to control group, the patients with insomnia had decreased sleep time [ （ 333.71 ± 84. 33 ） min vs. （403.65 ± 19. 29 ） min ] and sleep efficiency [ （70. 41 ± 17. 35 ） % vs. （83.45 ± 4. 42） % ], and increased sleep latency [ （39. 48 ± 24. 24） min vs. （ 19.65 ± 8.57 ） min], REM sleep latency [ （ 106. 60 ± 42. 89 ） min vs. （ 86. 80 ± 12. 25 ） min], proportion of S1 sleep time [ （25.36±14.22） % vs. （8.86±1.77） %] and awakening times [ （4.45±2.51） vs. （1.75± 1.07） ] . The proportions of S3±4 time [ （7.38 ±9.70） % vs. （ 13.78 ±4.24） % ] and REM sleep time reduced [ 114. 54 ± 5. 61 ） % vs. （ 19. 18 ± 2. 14） % ] （Ps 〈 0. 05 ） . According to the STAI, scores of both state anxiety [ （47.94 ± 8.96） vs. （ 39. 15 ± 4. 51 ） ] and trait anxiety [ （49.94 ± 8.90） vs. （42. 05 ± 7. 13 ） ] were significantly higher in insomnia group than in control group （ Ps 〈 0. 05 ） . State anxiety was positively correlated with sleep latency （ r =0. 42）, REM sleep latency （ r =0. 25 ）, awakening times （ r =0. 44 ） and proportion of S1 sleep time （ r =0. 34） （ Ps 〈 0. 05 ）, and negatively correlated with proportion of REM sleep time （ r = - 0. 41, P 〈 0. 01 ） . Trait anxiety was positively correlated with sleep latency （ r = 0. 37, P 〈 0. 01 ） and wakefulness frequency （ r = 0. 29, P 〈0. 05） . In return visits, the sleep structure improved, state anxiety score reduced, and trait anxiety had no significant changes. Conclusion： Patients with insomnia have significant sleep structural changes and higher state and trait anxiety. Their sleep structural changes are possilly related to state and trait anxiety.
