气郁质与失眠相关性的病例对照研究

目的：通过对睡眠质量以及中医体质的调查探索失眠与气郁质之间的关系。方法：对168名16~80岁的志愿者用中医体质量表、匹兹堡睡眠质量量表（Pittsburgh Sleep Quality Index, PSQI）、爱波沃斯嗜睡量表（Epworth Sleepiness Scale, ESS）以及深睡眠量表（Deep Sleep Scale, DSS）进行问卷调查。采用病例对照的方法分析气郁质和其他体质的睡眠质量和主要失眠症状。结果：分析结果显示气郁质患者睡眠障碍的症状主要表现为入睡困难（PSQI： OR=3.012, 95% CI=1.310~6.923; DSS： OR=3.016, 95% CI=1.358~6.709）以及早醒（PSQI： OR=3.545, 95% CI=1.229~10.232; DSS： OR=2.742, 95% CI=1.072~7.014）;而其他体质的人群主要表现为多梦（PSQI： OR=2.419, 95% CI=1.154~5.072; DSS： OR=2.561, 95% CI=1.116~5.880）。失眠症状与气郁质的程度之间存在相关关系,分析结果显示气郁质越严重,其发生入睡困难、早醒的危险系数越高。结论：本研究结果显示气郁质与失眠之间存在显著的相关性,对失眠的治疗与康复可以从调节中医体质的角度做进一步的研究。

Case-control study on the association between qi-stagnation and insomnia

OBJECTIVE： To investigate the relationship between insomnia and qi-stagnation by using the international standardized measurement of sleep quality and the Traditional Chinese Medicine （TCM） Constitution Scales.
METHODS： A survey by means of the TCM Constitution Scales, the Pittsburgh Sleep Quality Index （PSQI）, Epworth Sleepiness Scale （ESS） and the Deep Sleep Scale （DSS） in 169 participants aged between 16 and 80 years old was conducted. Comparison was made to examine the sleep quality and insomnia symptoms in the qi-stagnation group and other-constitution group.
RESULTS： Univariate analysis found that the qi-stagnation group had a significantly increased risk of difficulty in falling asleep （OR=3.012, and 95% CI 1.310 to 6.923 for PSQI; OR=3.016, and 95% CI 1.358 to 6.709 for DSS） and early waking （OR=3.545, and 95% CI 1.229 to 10.232 for PSQI; OR=2.742, and 95% CI 1.072 to 7.014 for DSS）, while the other-constitution group had a significant risk of dreaminess （OR=2.419, and 95% CI 1.154 to 5.072 for PSQI; OR=2.561, and 95% CI 1.116 to 5.880 for DSS）. A dose-effect relationship existed between insomnia symptoms and qi-stagnation. Qi-stagnation significantly increased the risk of difficulty in falling asleep and early waking.
CONCLUSION： This case-control study revealed that there is a statistically significant association between qi-stagnation and insomnia. Based on this study, we recommend that further research should be conducted for the rehabilitative care and cure of insomnia from the perspective of TCM constitution.
